First things first, this piece is really long. If you don't want to read it all right now, I recommend bookmarking it so you can come back to it later. This was originally going to be a Reddit text post, but it quickly exceeded the forty thousand character limit and now stands at about six times that amount, which is why I've moved it to a separate site. This also means I can continue to update the timeline for as long as new Adventure Time content is being released.
Secondly, this timeline contains all the spoilers, up to and including Come Along With Me, the finale. Please don't read it unless you've finished the show and you've read all the comics you intend to read. I also recommend you read The Enchiridion & Marcy's Super Secret Scrapbook, since a lot of the timeline draws from that.
I am from the UK, so one must pardon any British spelling or grammar.
Please leave your thoughts and criticisms in the comments section at the bottom of the page, and keep it civil. If you would like to message me privately, send a PM to one of my social media accounts, linked at the top of the page.
This piece was inspired by several Adventure Time timelines published before it. The main reason I started this project was because the timeline by RedLionKing has become very outdated and only deals with the core storyline of the show's past, although my version isn't quite as beautifully written so I recommend you check it out anyway. Also credit to this concise timeline by Viernes de Siluetas, from whom I stole the date system.
Thanks to Uncivilized Elk for his in-depth episode analysis videos which have inspired some details of the timeline, and thanks to all the editors and transcribers on the Adventure Time Wiki without whom this task would have been a lot more arduous.
Lots of credit to SpiderCider and Décadent for translating this entire piece into Korean. 🇰🇷 Click here! Although it hasn't been updated since The First Investigation came out and doesn't include any of the present day sections so it's quite out of date now. If anyone is interested in providing translations for any other languages, drop me a PM.
And of course, thanks to Pendleton Ward, Adam Muto, and the entire Adventure Time crew for creating one of the most deep, complex, and inspiring worlds in the history of children's television.
This timeline is designed to be as complete as possible. This means that not only am I drawing events from the show, but also from many other pieces of officially licensed material, including comics, video games, and graphic novels.
One question that gets thrown around a lot is "Are the comics canon?" The short answer is no. Adam Muto and Jack Pendarvis have both clearly stated that they are not. However, the comics are officially licensed, and many of them fit very neatly into the lore of the show. In fact, the only comics which are dramatically irreconcilable with the show are the Bag of Holding arc, in which Finn and Jake throw the Lich into the Sun, and the Seeing Red graphic novel, which contains a multitude of inaccuracies regarding Marceline's past. Other than that, there are only minor plot holes to overlook. Therefore, I'm going to treat the comics like an alternate timeline, which leaves me free to selectively choose which elements I include in the main timeline.
Click here for a list of every single piece of media which has been considered for the timeline. I have also considered things like promotional art and social media posts from members of the show's crew, although these are often tongue-in-cheek and shouldn't be taken as canon in every instance. Storyboards and other production material might also be sourced, but only for clarification; cut scenes do not count. Scrapped episodes also do not count.
Whenever I make a statement or pull a quote from somewhere, I will show the source in square brackets [like this]. That way, you can make up your own mind whether or not you choose to believe a certain element is canon.
All dates are organised around a year zero, which is the year of the detonation of the Mushroom Bomb and the impact of the Catalyst Comet. BMB stands for Before Mushroom Bomb and AMB stands for After Mushroom Bomb. The letter c before a date stands for circa, and indicates that this is an estimated date. The letter X is used to denote any digit (e.g. 99X could be any year from 990 to 999). A corresponding real-life date is displayed in brackets. Since the beginnings and ends of years are not clear, many events may be one year off. Where applicable, the New Year is assumed to be Finn's birthday.
For labelling things with a real-life date, I have assumed that 0 AMB = 2010 CE. See the section on the Great Mushroom War for evidence supporting this date.
The Mushroom Bomb and the war-time Catalyst Comet hit at approximately the same time. Uniting these two pivotal events makes it much easier to put a date to things, so I have assumed that they both take place in 0 AMB.
Before there was time - before there was anything - there was nothing. And before there was nothing, there were monsters.
The Lich [S06E26 Gold Stars]
Reality exists as an infinite chaotic sea of monsters, including beings like Orgalorg, GOLB, and possibly the Lich. By incomprehensible chance, the monsters eventually come to a common agreement on the state of reality, and this consensus becomes the Multiverse. Therefore, despite its appearance to those who inhabit it, the Multiverse is not actually material. The Multiverse is an emergent product of consciousness rather than consciousness being an emergent product of the Multiverse. Every sentient being that lives in the Multiverse paradoxically maintains its existence by experiencing it, and this also means that every sentient being has an existence beyond the material, known as their soul.
Third Orb does not exist, said the Sage.
Why? asked the Student.
Because the Multiverse, said the Sage, within which Third Orb exists, does not exist. The Multiverse is a Consensus Reality shared by the Minds of all Sentient Beings. If they were to Die, the Multiverse, as such, would suddenly blink out of existence, vanish, be no more.
Why? asked the Student.
Because, said the Sage, there would be no one to Perceive It.
Chapter One of the Wizards' Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
Other than this, the origins of the Multiverse are largely unknown. Nobody knows where the monsters came from or what the true nature of reality is. Everything we know about the world before existence comes from that single glimpse granted by the Lich.
Where did the Multiverse come from? Since logic dictates that asking this question must result in an infinite regression - What created the Multiverse? And what created the Thing that created the Multiverse? Etcetera - this suggests that the mental engine of logical thinking is not designed to determine the Answer.
Chapter One of the Wizards' Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
The Multiverse imagined by the primordial monsters is composed of a vast (perhaps infinite) number of "dimensions" which each hold a universe. One of these is the Earth Dimension, which contains the planet Earth (sometimes referred to as "Third Orb") as well as all the other planets, stars, and galaxies in our own universe. Other dimensions include the Astral Plane, the Crystal Dimension, Lumpy Space, the Nightosphere, the Citadel, and many more. Amidst this complex system of dimensions is the Time Room:
At the centre of the Multiverse is a dimension called the Time Room, believed to be the quasi-corporeal dwelling place of the almighty Prismo. The Time Room is the single dimension that exists outside of time. The Time Room produces time waves that are experienced by other dimensions. Some dimensions have permanent links that allow travel to and from. Others become linked temporarily by naturally forming wormholes. And others can become linked artificially by magical portals, torn open by items of great power. An activated portal creates a time dilation in which either end of the portal experiences a temporal synchronisation allowing for the safe passage of particles through a non-local region of space-time.
Booko [S04E26 The Lich]
The physics behind the concept of the Multiverse is somewhat explained in chapter four of the Wizards' Enchiridion, albeit in a very hand-wavy pseudo-scientific way. To prevent all of the dimensions from catastrophically colliding with one another, all particles in a specific dimension have their own unique "frequency". Particles with different frequencies reside in different dimensions. Adjusting this frequency allows for interdimensional travel. Another property of each dimension is its "elasticity", which determines how easy it is to change the frequency of particles within that dimension. As stated above by Booko, dimensions can be interlinked if the frequencies of the particles in a local region of both dimensions can be somehow synchronised, hence forming a kind of gateway called a "portal". The more elastic a dimension is, the easier it is to open a portal. A very rudimentary form of temporal synchronisation is demonstrated by Finn when he interacts with the little people, who reside in "a different dimensional plane" according to Jake. Finn shakes the little people, which synchronises their frequencies enough to allow for brief interdimensional communication. [The Enchiridion & Marcy's Super Secret Scrapbook, S05E05 All the Little People]
The elasticity of a dimension has other effects besides ease of interdimensional travel. For example, highly elastic dimensions are more easily influenced by magic (more on that in a couple of sections), and are more likely to allow for interspecies hybrids to be born. The most extreme known examples of hybrids seen in the show are Jake's descendants, who contain genes from at least four species; bears, rainicorns, dogs, and shape-shifters. The elasticity of a dimension can vary with time. Earth was elastic in the time of the dinosaurs, then became very rigid during modern times, then elastic once again following the detonation of the Mushroom Bomb. [S06E12 Ocarina, S06E24 Evergreen, S08E08 Elemental]
One final principle of the Multiverse is the concept of "Amok Time", which states that causality can sometimes be reversed. This allows for accurate predictions of the future and the occasional bit of time travel. At the very beginning of time there is a place called the Vanishing Point, and anyone who gets trapped there will be erased from history. Jake the Dog claims to have seen the Big Bang while travelling back in time to visit the Vanishing Point. [The Enchiridion & Marcy's Super Secret Scrapbook, Beginning of the End #3]
Note: A slightly more scientifically rooted explanation for the structure of the Multiverse is alluded to in storyboard panels from Crossover. The panels cite a 1994 Scientific American article by physicist Andrei Linde which talks about the eternal inflation model. However, this model has never been explicitly referenced in the show and is pretty much irreconcilable with the other model.
It's also worth mentioning that time travel is handled quite differently in the comics compared to the show. In the comics it is a frequently used plot device, with instances of time travel happening in several arcs including the Time Machine arc, Banana Guard Academy, the Cosmic Elementals arc, Beginning of the End, and the first arc of Season 11. On the other hand, the only real instances of time travel which occur in the show are Betty travelling into the future and the time slips in The First Investigation. Princess Bubblegum even makes it clear that she is not able to produce a "real" time machine in Bad Timing.
Prismo, who was briefly mentioned earlier, is one of the many god-like "Cosmic Entities" who inhabit the Multiverse and make up the pantheon of Adventure Time. Most of them have a specific purpose within the elaborate clockwork of existence:
It can sometimes be unclear who is and is not a Cosmic Entity. In addition to those above, the fan wiki lists Grob Gob Glob Grod, Party God, Cuber, Life, the Elementals, Finn, Martin, and the Lich as Cosmic Entities. A deity named Malus, who bears a striking resemblance to the real life pagan deity Abraxas, is also seen in one of Simon's books on GOLB. [Wiki: Category:Deities and Cosmic Entities, S10E15 Come Along With Me Part 3]
Prismo apparently has a "boss" whose identity is unknown. [S07E23 Crossover]
Adventure Time has done a surprising amount of exploration around what might happen after you die. There appear to be four main possibilities:
It is implied that ending up in a higher Dead World is a more desirable outcome. The highest ever mentioned in the show is the Fiftieth, which appears to be the equivalent of Heaven and is probably synonymous with "Glob World". [S03E24 Ghost Princess, S05E21 The Suitor, S03E18 The New Frontier]
According to Jake, lower Dead Worlds are the worlds containing ghosts, which overlap with the material world. [S06E17 Ghost Fly]
What is the Origin of Wizardry? Pour yourself a cold glass of lemonade, sit in a comfy chair, kick your shoes off, lean back, close your eyes, and think. If reality is Mental in nature, analogous to a Cosmic Mind, and if Wizardry is a function of the Imagination, then the Forces of Nature in the Multiverse are akin to the Currents of the Cosmic Imagination. Thus, the Origin of Wizardry is at the Core of Creation, and Wizards can create or destroy as they wish, tapping into the Power of the Cosmic Imagination.
Chapter One of the Wizards' Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
Since the Multiverse is maintained by the perceptions of the sentient beings within it, the imagination can actually be used to change the very structure of existence. This practice is most commonly known as "magic" and used almost exclusively by witches and wizards, although others can also learn to manipulate the material world using their mind.
However insecure a wizard might be, wizardry is the realm of the Imagination, and even the flabbiest, most flop-sweaty wizard can warp your perceptions enough to make you believe they are fully capable of kicking your butt.
Chapter Two of the Wizards' Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
Magic most commonly manifests itself in the form of spell-casting, in which magic users recite incantations and channel their imagination through magically charged items in order to produce various effects. They usually have to practice one trick over and over until they are able to consistently perform it, which is why most magic users have a unique but limited arsenal of spells. There are other methods of performing magic as well. For example, Finn has performed magic via meditation and song, and Son of Rap Bear can produce explosions by rapping. [The Enchiridion & Marcy's Super Secret Scrapbook, S03E07 Still, S06E43 The Comet, S10E03 Son of Rap Bear]
According to Betty Grof's MMS theory, all magic users have varying levels of magic, madness, and sadness. These three properties are required in order to reliably perform magic. Therefore, individuals with tragic pasts are more likely to be drawn into the world of wizardry, and other individuals may be driven to madness and sadness if they attempt to pursue magic. The three traits enforce and balance each other. [S06E38 You Forgot Your Floaties]
There are two perspectives on the concept of magic. Scientists like Princess Bubblegum believe that it happens due to observational quantum effects and is grounded in scientific principles. On the other hand, magicians choose not to question the methods by which magic is possible, and, thanks to this blind belief, they are far more proficient at performing it. Neither view is incorrect. [S05E26 Wizards Only, Fools]
The Enchiridion is an ancient tome and one of the most powerful magical artifacts in the Multiverse. Its exact origin is unknown, but the author is implied to be the reader. Over the course of all of history, it is written and enchanted by thousands of wizards. These spells cause it to gain sentience, change with every reading, automatically translate into the reader's native language, and contain knowledge from the past and future. The original tome is over eight million pages long. Various abridged copies are eventually produced, all of which retain its magical properties. The tome is split into two books: one for heroes and one for wizards. It teaches heroes how to conduct themselves and best serve their wizard masters, and it teaches wizards how to perform many ancient and secret forms of magic. [The Enchiridion & Marcy's Super Secret Scrapbook]
Every ten thousand years, the Enchiridion transports its original author to the Time Room, where they must make a choice. They can either force the Multiverse to reset to how it was ten thousand years ago, or they can allow it to continue into the unknown. The author almost always chooses to have it reset.
Since we've done this thousands of times, you may feel this Universe has been played out, so to speak. Every other time, you've decided to go back in time and start over, to that moment in the quarry when you were carving your name and your true love's name into the side of the boulder, when you first conceived of writing The Enchiridion. You were the young Wizard who wrote it, but you've forgotten. When I become sentient enough to tell you, after ten thousand years, I remind you and ask you if you'd like to end it all and let the Unknown occur, or if you'd like to go back again and experience another variation of the last ten thousand years. The Multiverse is unstoppable. Even if it ends, it will sprout back into existence again, but this time in some new, unknown way. Just as it did when all of This began. I'm just asking. It's your decision.
The Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
It is somewhat unclear how this cycle fits into the rest of the history of the Multiverse.
Placing gems into various slots in the Enchiridion can produce powerful magic spells. Most notably, filling the gem slots in the front cover enables the user to open a portal to any dimension in the Multiverse, and might even allow for time travel. [S04E26 The Lich, S09E09 Skyhooks II]
The planets Earth and Mars form in the Earth Dimension around a sentient star called the Sun. [S06E10 Something Big]
On Planet Earth exists the concept of five fundamental elements: Fire, Ice, Candy, Slime, and Lumps: parodying the real-life (but false) classical elements of fire, water, earth, air, and aether. These will become important later on. [S08E08 Elemental, S09E09 Skyhooks II]
A demon named Hunson Abadeer comes into being around this time:
My single earliest memory occurred eons before the Mushroom War. This memory consists of one image: me eating a ham sandwich, perched atop Rock Candy Mountain, overlooking the Sea of Something, long before Plants, Animals, and Actual Things came into existence in the Land of Ooo, surrounded by an all-encompassing Night of Nothingness. Full disclosure: I believe I was a ghost at the time, although it isn't clear how a ghost can sit on a mountain peak or eat a ham sandwich.
Hunson Abadeer, in the Encyclopaedia [The Adventure Time Encyclopaedia]
Note: This excerpt suggests that the Land of Ooo has existed since the beginning of life on Earth, but this is now known to be false since it did not form until after the Great Mushroom War.
It is not known if Hunson Abadeer was once a living being, or if his soul simply came into existence out of nothing. Even he admits to not knowing his own origin. Once he manifests a physical demon body, he and most other demons end up living in a hellish dimension called the Nightosphere. He claims that he was a carny boss in his youth, going by the name Johnny Corndog. [The Adventure Time Encyclopaedia]
Aside from Earth, a multitude of other planets in and around the Solar System are also inhabitable. Eventually, interplanetary travel becomes widespread enough that many of them are able to communicate with one another, forming the backbone of an interstellar community. As far as we know, Earth never makes contact with its neighbours. [S06E41 On The Lam]
Currently, these are the other worlds within the Earth Dimension where life is known to exist:
Note: The fan wiki spells the name of this world "Ni'Rah". However, the spelling given by television subtitles is "Nerraw", which makes more sense given this is Warren's name backwards. Nerraw is known to be within the Earth Dimension because in Temple of Mars, King Man makes fun of Jermaine for saying that it's somewhere in space, pointing out that "literally every single thing in this dimension is in space".
The technological level of most interplanetary civilisations is unknown. Some creatures, such as the giant moth, appear to be capable of faster-than-light travel, given the fact that Martin travels from the planet of the koala people back to Planet Earth in a very short time. [S06E43 The Comet]
Ever since life began on this planet, there have always been embodiments of the four elements: Fire, Ice, Candy, and Slime. Across eons and millennia the four Elementals lived, and died, and lived again.
Patience St Pim [S08E08 Elemental]
The Elementals are powerful wizards who live on Earth and each represent one of the aforementioned elements. They possess the power to generate and shape their own element in a variety of ways. Whenever an Elemental dies, their soul is reincarnated into a new body, meaning that there is almost always a living representative for each element at any one time. The Elementals can occasionally make contact with their past lives. [S06E24 Evergreen, S08E19 Jelly Beans Have Power]
The fifth element, Lumps, behaves as an "anti-element", and also has an associated Elemental to go with it. The Lumps Elemental is capable of undoing the magic of the other four, as well as some other types of transfiguration magic. Furthermore, Lumps apparently permeates through the universe, similar to aether, its classical counterpart. A Lumpy Space person is seen on the planet of the koala people, suggesting that Lumpy Space is accessible from anywhere in the universe. [S09E09 Skyhooks II, S06E41 On The Lam]
Lumps are the subspace molecular lattice that binds together the scientific and magical forces of Ooo. More powerful than any one element, it's the force that orders reality into its true shape.
Lumpy Space Queen [S09E09 Skyhooks II]
Like all magic users, the power of the Elementals is entirely dependent on the elasticity of the Earth Dimension. For example, Evergreen, who lived millions of years in the past, is capable of constructing an entire castle from ice, whereas the Fire Elemental of the pre-war era struggles to heat a single cup of coffee. [S06E24 Evergreen, S08E08 Elemental]
The symbol used to represent the main four elements is a circle divided into quarters ⊕. This is also the real-life astronomical symbol of Planet Earth. [S08E19 Jelly Beans Have Power]
At one point, four Cosmic Entities each rule over one of the four elements:
Zon, Arklothac, and Ng'zot Aa reap the Earth for many years, terrorising the fledgling life that has begun to appear. Lun takes pity on the inhabitants of Earth and decides to take action against the other Elementals. She betrays them and has them locked outside the Earth Dimension so that they can do no further harm. To prevent the evil Elementals from ever returning, Lun sacrifices herself to create the Sword of Lun, a weapon capable of destroying them. Before being used, the sword must await its true bearer, "a warrior who can withstand great bodily loss without injury". [Adventure Time #59 and #61]
As a result of this event, the Ice Elemental's betrayal would go on to echo and repeat itself several times through history. [S06E24 Evergreen, S08E08 Elemental]
At around the same time, a Cosmic Entity known as the Catalyst Comet begins its millennial cycle:
Every one thousand years, the Catalyst Comet mysteriously reincarnates itself and collides with Earth, bringing with it an Agent of Change.
Grob Gob Glob Grod [S06E25 Astral Plane]
Every comet strike brings great change to the world by delivering a being known as an "Agent of Change" or "Comet Avatar". Sometimes, the Agent of Change will succeed in turning the world into a better place. But sometimes, the comet delivers great evil into the world, and an era of destruction and death ensues. Like the Elementals, the Agents of Change are reincarnated after death so that they can continue their mission over the course of more than one lifetime. [S06E43 The Comet]
The Comet takes on a different colour every time it strikes. So far, four have been depicted: Green, Yellow, Blue, and Purple. The stories behind each of them, and the stories behind the Agents which they spawn, form a core part of the lore of the show and will be explained later in the timeline.
During the time of the dinosaurs, the four Elementals are Urgence Evergreen (Ice), Balthus (Fire), Chatsberry (Candy) and Slimy D (Slime). The Lumps Elemental of this time is never mentioned. Evergreen the Ice Elemental has a mutated dinosaur servant named Gunther, who vainly hopes to eventually become his master's magical apprentice. Gunther briefly meets Finn and Jake while they are travelling through time after escaping the Vanishing Point. This is the first of several cameos they make throughout history during this journey. [S06E24 Evergreen, Beginning of the End bonus chapter]
Evergreen spots the impending Green Catalyst Comet and notices that it is far more powerful than those that have come before it. It carries so much power that it would wipe out most of the life on the planet, so Evergreen seeks a way to stop it. He uses his knowledge of technology and magic to construct a golden crown capable of granting its wearer their greatest wish, but it needs a power source: the ruby eyes of the lava dog Magwood. To help battle Magwood and retrieve the eyes, Evergreen summons the other three Elementals to his castle from their respective realms. They reject his plan, stating that wish magic is too dangerous and reminding him that even if they die, they will be reincarnated:
Hath not a Comet impacted our world every thousand years with no lasting grievousness? If this Comet hits, we four indeed may perish, but the elements we embody - Fire, Ice, Candy, and Slime - will live on. But a misplaced wish could cause irreversible damage to the very structure of existence.
Balthus [S06E24 Evergreen]
Ignoring their advice, Evergreen has them frozen and sets off to take on Magwood alone. His mission is successful and he retrieves the eyes before rushing them back to his castle and completing the crown. However, just as he is about to use it to vanquish the Comet, he is attacked by Magwood, who begins to knock down sections of the castle in its blind rage. Evergreen becomes trapped under debris and is unable to put on the crown and wish for the Comet's destruction, so he instead orders his dinosaur servant Gunther to do it. But Gunther's greatest desire is not to destroy the Comet.
Instead of stopping the Comet, Gunther's truest, deepest wish came true. His nose lengthened, white hair grew from his head, and a beard descended from his face as the crown changed Gunther into Evergreen. Snow began swirling within the room. Evergreen was horrified. The Comet had arrived. It was all too late.
Chapter Five of the Wizards' Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
The comet kills the four Elementals, and is likely to be the event which causes the extinction of the dinosaurs. The crown saves Gunther by storing his consciousness in its circuitry. In the future, any individual who wears the crown will turn into Gunther's image of Evergreen: a mad and powerful ice elemental. [S08E01 Broke His Crown, S03E20 Holly Jolly Secrets Part II]
It is likely that the Green Comet's Agent of Change is the Lich, an embodiment of evil whose only desire is to extinguish all life. He is "the last scholar of GOLB", although the exact meaning of this is unknown. Since the Multiverse is maintained by the conscious beings within it, the end of life would mean the end of the Multiverse, and reality would return to its initial state of chaos and monsters. This is probably the Lich's ultimate goal. The Lich lies dormant for millennia, awaiting the right opportunity to rise to power. [S05E01 Finn the Human, S09E13 Whispers]
The extinction of the dinosaurs allows mammals to dominate the planet, and eventually this leads to the evolution of vampires and humans.
When my Dad was trying to wise me up to the ways of the world, he told me that the race of vampires were ancient. He said they'd been on Earth before humans, and that when the Ice Age began, they hibernated underground until it was over.
Marceline, in her scrapbook [The Enchiridion & Marcy's Super Secret Scrapbook]
Vampires are terrifying humanoid creatures who suck the blood from the necks of other creatures for nourishment and are capable of turning their victims. However, vampires in Adventure Time do not actually feed on blood itself, instead taking their sustenance from the colour red. This doesn't stop most vampires from feeding on blood anyway. They remain mostly hidden from the human population until after the Great Mushroom War. [S01E12 Evicted!, S07E08 Vamps About]
Werewolves also seem to be native to Earth, so probably evolved at around this time. [The Enchiridion & Marcy's Super Secret Scrapbook]
Earth is not the only place in the Solar System harbouring life. At some point, a utopian society emerges on Mars following a conflict known as the "Martian Independence Era". [Marcy & Simon #5]
It is not clear where they came from, but it has been theorised that they are advanced humans who became somehow transported back in time. This theory is supported by the following facts:
Lincoln's champion is the four-faced Grob Gob Glob Grod, who later becomes entwined in the religious beliefs of the inhabitants of Earth. Glob has a brother named Magic Man, and Magic Man has a wife named Margles.
Mars is attacked by the ancient Cosmic Entity known as GOLB, the embodiment of chaos, who consumes Margles and completely removes her from existence. To prevent his second coming, Magic Man builds a defence system called the Magical Automated Resistance Generating Laser Energy Supplier (M.A.R.G.L.E.S.) in the image of his late wife, and plans to install it on the peak of Olympus Mons.
I looked everywhere, you know. Every dimension, every Dead World. I even wished you back in Prismo's Time Room, but you were gone - erased. For hundreds of years I held that sadness until my magic and science were strong enough to create you from my nightmares.
Magic Man talking to M.A.R.G.L.E.S. [S06E38 You Forgot Your Floaties]
Unfortunately, Magic Man's grief has corrupted his spell programming, and the new defence system goes insane and has to be deactivated. Magic Man begins to spiral into madness after effectively losing his wife for the second time. He torments the people of Mars for centuries to come. [S04E15 Sons of Mars, S06E38 You Forgot Your Floaties]
This event is witnessed by Finn and Jake while they are travelling through time after escaping the Vanishing Point. [Beginning of the End bonus chapter]
A very, very long time ago, the Nightosphere was a very different place. It was chaotic. Lawless. A real nasty place. That's about when my dad showed up. He got sick of nothing getting done, everybody eating everybody else. These two old, evil globs, they liked things just how they were. My dad had different ideas. He worked old magics for a hundred days and nights - taking snack breaks, obviously - until he made a weapon that could win the Nightosphere.
Marceline [Seeing Red]
The demon Hunson Abadeer constructs the Abadeer Axe and uses it to defeat the previous rulers of the Nightosphere, becoming the new Lord of Evil. His rule is cruel and tyrannical, but apparently still better than that of his predecessors. [S04E06 Daddy's Little Monster, Seeing Red]
According to Hunson Abadeer's encyclopaedia, the ancient demons were "trepanning fetishists" who attached engraved iron plates to their skulls containing ancient secret knowledge. [The Adventure Time Encyclopaedia]
Later on, Hunson Abadeer and Death begin to compete for the souls of the recently deceased. Hunson tries to encourage them to become demons and join his subjects in the Nightosphere, while Death tries to encourage them to come with him to the Dead Worlds. At one point the two rivals are both members of the same cover band. Hunson kicks Death out for being a better drummer than him. [Adventure Time #53, The Adventure Time Encyclopaedia]
Also around this time, Hunson Abadeer meets Abraham Lincoln. [S04E05 Return to the Nightosphere]
By this time, the Crystal Dimension is mainly inhabited by two species: the Korean-speaking magical rainbow-unicorn creatures known as "rainicorns", and a race of intelligent talking dogs. For an unknown reason, the two species fall into multiple disputes over the course of many millennia, eventually leading to the outbreak of war. Not much is known about how the wars play out, nor who wins, although it seems to involve one or both sides engaging in aerial flying saucer combat. [S02E12 Her Parents]
All of rainicorn history is documented in the Rainicornicopia. [S03E22 Paper Pete]
For thousands of years rainicorns battled dogs for territory in the Crystal Dimension.
Jake [S02E12 Her Parents]
Finn and Jake briefly witness the war while travelling through time after escaping the Vanishing Point. [Beginning of the End bonus chapter]
A few details of the closing years of the war will be explored later in the timeline.
Note: This extremely long time scale could be an exaggeration on Jake's part. The wars might only have gone on for a few years or even less.
One of the monsters from before the beginning of existence is Orgalorg, an evil Cosmic Entity.
Orgalorg is an ancient Cosmic Entity who ruled the Solar System with his cruel and deadly whims: The Breaker of Worlds. He was seeking ever more power. He desired to intercept a Catalyst Comet and absorb its essence. Thereby did he offend the King of Mars, who decreed that Orgalorg should be cast down. And yes, he was cast down, by the flaming sword of Grob Gob Glob Grod. Orgalorg was banished to an inhospitable planet where he would forget everything. Yea, even forget his identity and from whence he came. And the prophets say that the gravity of the planet did crush and compress Orgalorg into a more powerless and cuddlesome form.
Alien Elders [S06E40 Orgalorg]
Finn and Jake witness the battle between Orgalorg and Glob while they are travelling through time after escaping the Vanishing Point. [Beginning of the End bonus chapter]
The powerless and cuddlesome form of Orgalorg is an immortal penguin who will much later become known as Gunter. He becomes a hunter-gatherer alongside early humans. [S06E40 Orgalorg]
Meanwhile, the Yellow Catalyst Comet strikes the Earth and leaves behind its Agent of Change. Given the colour scheme, it's possible that this Agent of Change will eventually be reincarnated as Jake the Dog, although this has not been confirmed.
Note: This probably takes place after the first coming of GOLB because Glob is wearing their "groovy headgear" to hide their baldness during their fight with Orgalorg.
Orgalorg/Gunter's gender is ambiguous. However, all characters in the show assign him male pronouns so I will too.
A powerful shape-shifter named Warren Ampersand wishes to live forever, so he creates a plan to drain the youth from his own children. Every generation, he impregnates a chosen host so that their offspring inherit his powers. Later in his children's lives, he lures them to his homeworld, Nerraw, where he tricks them into shape-shifting while wearing a special belt which drains their power and gives it to him.
I was dying. I needed to siphon your precious stretchy essence to keep me young and virile. I use these belts as a conduit. The more you stretch the stronger I grow. I've done it hundreds of times, to hundreds of sons.
Warren Ampersand [S10E10 Jake the Starchild]
He would continue this sick trickery for many generations, exploiting and then outliving each child in succession. One of his future sons would be Jake the Dog.
The penguin form of Orgalorg appears in some hieroglyphic artwork from the time of the Ancient Egyptians, implying that he joined their society. Construction of the Egyptian pyramids is completed in approximately 2560 BCE, and Charlie, one of the children of Jake the Dog, would study tarot reading and divination there thousands of years later. As humans continue to develop and thrive, the elasticity of the Earth Dimension settles into a more rigid pattern, bringing about the end of magic. For now. [S06E40 Orgalorg, S08E11 Daddy-Daughter Card Wars, The Enchiridion & Marcy's Super Secret Scrapbook]
A race of magical rock people live on Earth. After magic fades from the world, they are banished by early humans, and live in subterranean lairs for the next few thousand years, eventually coming to call themselves "The Underground". [Adventure Time Comics #20: "Cavities"]
During the height of the Roman Empire, the penguin form of Orgalorg is a gladiator and a chariot racer in Ancient Rome, and is depicted in some pottery from the time. [S06E40 Orgalorg]
The legend of the Dual Swords takes place during the time of the Ancient Romans:
Legend tells of two mighty gladiators, as bonded to each other in friendship as two sides of a coin, who were made to fight a death match by their wicked emperor. When one of the Heroes' swords was unexpectedly stolen by a flying serpent who liked shiny things, the other Hero split his own sword in half, and the two gladiators each fell on one half in defiance of the cruel emperor's order. Throughout the centuries, the Dual Swords have been separated many times by merchants, curio collectors, and thieves, but they always seem to find their way back together.
Chapter Three of the Heroes' Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
Thousands of years later, the Dual Swords would end up back together in the arena of the Fight King, who is likely an immortalised version of the evil emperor. [S03E02 Morituri Te Salutamus]
During the middle ages, he joins some kind of hooded organisation: possibly a monastery or a secret society. During the Elizabethan era, he lives in Britain and appears alongside Elizabethan nobles. [S06E40 Orgalorg]
In Ancient Greece, Saint Nicholas comes into possession of Evergreen's crown and wears it. Like the dinosaur Gunther, the original Santa's consciousness becomes stored in the circuitry of the crown. He briefly gains the powers of the Ice Elemental, which could be the cause of Santa Claus' later association with snow and ice. It is unknown whether he is able to overcome the crown or if he succumbs to it until it finds its next host.
Says he's the first "Santa". Like, what's even a Santa?
Gunther's consciousness [S08E01 Broke His Crown]
Likewise, the consciousness of an Icelandic boy named Sveinn becomes stored in the crown's circuitry after wearing it just once. Given his heritage, it's possible he has some relation to the Scandinavian dockworker who would later sell the crown to Simon Petrikov. [S08E01 Broke His Crown, S03E20 Holly Jolly Secrets Part II]
That's Sveinn. He only wore the crown once.
Gunther's consciousness [S08E01 Broke His Crown]
The fact that he wore it so briefly suggests either that he is able to overcome its influence or that he dies not long after wearing it.
Note: Sveinn only says a few words in the episode, making it hard to determine which Nordic language he is speaking. However, the storyboards specify that it is Icelandic.
Despite taking a fatal gunshot to the head, Abraham Lincoln manages to make some kind of deal with Death, bribing him with a penny. Instead of being killed, he becomes immortal and travels back to ancient times, where he becomes the deific King of Mars and rules the Martian colony. The story behind why this happened is not known. It is probably best not to question it. On Mars, Abraham Lincoln is prophesied to someday meet Jake the Dog. [S04E15 Sons of Mars]
Look. It's the dog. The one you were prophesied to meet.
Grob Gob Glob Grod [S04E15 Sons of Mars]
Sometime around the dawn of the twentieth century, the penguin form of Orgalorg opens a drinks manufacturing company called "Gunto's" and becomes fairly wealthy thanks to its success. He owns a car (closely resembling a Ford Model T) and probably still lives in Britain. It seems unlikely that an immortal penguin god would be able to adapt and blend in so well with modern society, but somehow Orgalorg manages to do so without raising too many eyebrows. [S06E40 Orgalorg]
Note: Orgalorg has not yet been renamed Gunter at this point, so the similar name of the company must be a coincidence.
During the First World War, he becomes a fighter pilot for the British Royal Air Force and flies a biplane resembling a Sopwith Camel, which entered service in 1917 CE (93 BMB). It is unknown whether or not Orgalorg has any involvement in the Second World War, but at some point he becomes a movie director. By the seventies, he has moved to the United States where he joins the counter-cultural movement. [S06E40 Orgalorg]
You will no longer terrify a forty-seven year old man and a seven year old girl!
Simon Petrikov in 2 AMB [S05E14 Simon & Marcy]
Simon Petrikov is born to unknown parents. Based on his name and the fact that he ends up attending the University of Petrograd in St Petersburg, he is probably raised in Russia. [The Enchiridion & Marcy's Super Secret Scrapbook]
You know... this reminds me of something my mother told me when I was, oh... a little older than you, I think. She said that no matter how broken something may be, there will always be a way to fix it again.
Simon Petrikov [Adventure Time Comics #16: "Broken"]
While he doesn't seem like much at the moment, Simon would eventually undergo a series of unfortunate tragedies leading to his transformation into the Ice King. His story will be explored much more deeply in a while.
After the death of an unknown previous Elemental, the spirit of the Ice Elemental is reborn as Patience St Pim. She and the other Elementals of the modern generation discover their powers and eventually find one another, although their powers are weak due to the rigidity of the Earth Dimension at this time. [S08E08 Elemental]
Ha, I remember being eighteen. I'm twenty-eight.
Patience St Pim [S08E08 Elemental]
By this time, Patience is already making plans for an "elemental purification spell" which she plans to use to re-establish the four elemental realms. She briefly meets Finn and Jake on the streets of a city while they are travelling through time after escaping the Vanishing Point, and rants to them about her plan.
Purity, that's the key! The purity of the elements! I can smell the magic humming off you two, but in this era there's hardly a whisper of the stuff! I need to get myself to some other time, where the magic has more juice! More grit!
Patience St Pim [Beginning of the End bonus chapter]
Despite his comfortable integration into human society, Orgalorg somehow realises that he is something more than just an immortal penguin. Since it was the gravity of the planet Earth which compressed him into his current weak form, he recognises that he must attempt to escape into space so that he can take his true form. Meanwhile, a man named Davey Johnson works a desk job at a space agency and is a previous life of Finn Mertens. He is offered the chance to go to space but declines, and thanks to this decision he spots Orgalorg trying to steal the rocket and has him apprehended. [Adventure Time #50]
Note: Davey was alive before the war, meaning that if the Blue Comet struck at the same time as the war then Davey was actually a previous life of the Blue Comet rather than a future reincarnation of it. This suggests that the Catalyst Comet is not the "original" progenitor of the Agents of Change, so the existence of Davey should probably be taken with a pinch of salt. See "The Blue Catalyst Comet" for more discussion about the placement of that comet.
Space travel develops significantly faster than in real life, to the point where humanity constructs a large functional base on the Moon before the Mushroom War. [Adventure Time #60]
In addition, a Mars rover (resembling the real life Mars rovers Opportunity and Spirit) possibly discovers evidence of the Martian civilisation, pictured above. [Sons of Mars title card]
Magic has mostly died out by modern times, with the great heroes and wizards of old becoming nothing but myths and legends. However, there still seems to be a vague awareness of the existence of magic and it is suggested that a number of people still believe in it:
Now, I never believed in the supernatural stuff myself - just had a fascination with superstitions.
Simon Petrikov, in his tapes [S03E20 Holly Jolly Secrets Part II]
Simon Petrikov and Betty Grof are both post-graduate antiquarians studying ancient artifacts and their relation to magic at the University of Petrograd in Russia. They meet each other in June in about the year 1990 CE, just before Betty was due to leave on a six month trip to study petroglyphs in the Australian outback. She cancels the trip and becomes almost obsessed with Simon. [The Enchiridion & Marcy's Super Secret Scrapbook, Adventure Time/Regular Show #4, S10E11 Temple of Mars]
I never took that trip. I met Simon the next day and he was just so... amazing. I put everything on hold to help him search for the Enchiridion.
Betty Grof [S10E11 Temple of Mars]
Remember how we first met, when we both reached for the same book in the library, and I said you should check it out first, and when you returned it you left a note inside because you knew I'd borrow it next? It was the funniest, smartest note I've ever read.
Simon Petrikov's consciousness [S08E01 Broke His Crown]
Our first official date? Well, I suggested skating, and you went along with it even though you didn't know how. You kept falling over and over but would never admit that you just never learned how to skate.
Echo of the Lich impersonating Betty Grof [Adventure Time #19]
Betty eventually becomes Simon's fiancée and they co-author a book called Mystic Rituals and their Space Time Applications. Simon's research into the arcane leads him to discover the existence of GOLB, but he is hospitalised after Betty tries to throw him a jar of cherries and he doesn't get any further research done on the subject. [S05E48 Betty, S10E15 Come Along With Me Part 3]
Look Betty, I keep seeing reference to this mysterious entity that embodies chaos. His presence is felt in every crevice where chaos lurks. Imagine if we could somehow harness all that dank energy.
Simon Petrikov [S10E15 Come Along With Me Part 3]
Following that, Simon discovers two major artifacts on his expeditions which challenge his previously sceptical perspective on magic. The first is Evergreen's crown, which he purchases from an old dockworker in Northern Scandinavia. The second artifact is a copy of the Enchiridion, which he discovers with help from Betty. [S03E20 Holly Jolly Secrets Part II, The Enchiridion & Marcy's Super Secret Scrapbook]
On my recent expedition to Islamabad, in a secret vault in the Hindu Kush Mountains, I discovered an incredible artifact - an ancient book known as "The Enchiridion". Laboratory analysis of the paper and ink indicates some of the pages in the second half of the book pre-date recorded history and are composed of plant DNA unknown on Earth.
Simon Petrikov, in his letter to Betty [The Enchiridion & Marcy's Super Secret Scrapbook]
After returning home from these expeditions, he presents his findings at the Museum of History, but the discoveries receive little recognition. A journalist named Bruce Guese writes a demeaning article, pictured above. [S04E25 I Remember You, Transcript of above image]
Simon returns to Betty and shows her the crown, putting it on his head as a joke. Suddenly, his head is filled with "secrets of the ice and snow" as the crown continues to fulfil Gunther's wish from all those millions of years ago, and his transformation into a mad ice wizard begins. He chases Betty through the streets, shouting for his princess and firing icy blasts from his hands. While Betty is hiding around a corner, a portal suddenly appears beside her and a version of Simon from a thousand years in the future speaks to her through it. Simon tells her that she disappeared after he wore the crown, and, realising why, she jumps through the portal and joins him in the future. Following Betty's mysterious disappearance, the present day Simon begins to lose his sanity as he slowly succumbs to the crown. He records tapes documenting his physical and mental transformation. [S05E48 Betty, S03E20 Holly Jolly Secrets Part II]
The visions. I fought with them. Shouted at them until I realised it wasn't real, it was the crown... Since then, I see the visions always, whether or not I wear the crown. They tell me the secrets - the secrets of the ice and snow - that the power of the crown will save me with its frost. I don't yet know what this means. As you can see, my skin is beginning to turn blue. My body temperature has been lowering at a supernatural rate, to what is now about 30°C. I don't know when it will end. I'm really scared.
Simon Petrikov, in his tapes [S03E20 Holly Jolly Secrets Part II]
Note: In Holly Jolly Secrets Part II, Simon states that when he took off the crown he saw Betty "staring at him with such contempt". However, in the episode Betty it is shown that Betty escaped to the future while Simon was still wearing the crown. It's possible he wore the crown once and then for some reason put it on a second time before Betty left.
Like with its other hosts, the crown stores a copy of Simon's consciousness in its circuitry. [S08E01 Broke His Crown]
Marceline is a half-demon half-human hybrid, born just five years before the end of the world. Her father is Hunson Abadeer, the demonic ruler of the Nightosphere, and her mother is an unnamed human from Earth. It is not known how this unlikely relationship arose.
Then he said "fine". And that's the story of how I met your dad.
Marceline's mother [S07E07 Everything Stays]
It is also not clear exactly how involved Hunson is in his daughter's childhood. In her scrapbook, Marceline says that she doesn't know anything about him until they meet after the Great Mushroom War, but pictures of her as a child can be seen in his castle, suggesting her parents maintain some form of contact. [S04E05 Return to the Nightosphere]
It seems like Hunson leaves them on their own them at some point shortly before the war:
Look kid, I want you to know I didn't abandon you. You have no idea how hard it was to let you go. Times were tough - even you know that. Your world was ending, and my world devolves into lawlessness when I'm not there.
Hunson Abadeer, in Marceline's scrapbook [The Enchiridion & Marcy's Super Secret Scrapbook]
Note: The Adventure Time Encyclopaedia, Seeing Red, and other secondary sources published before the Stakes miniseries suggest that Marceline grew up with her father and was a vampire from birth. This is completely false.
For some reason, Marceline has almost no memory of her life before the war, so her memories of her mother are also faded. When she is very young, they go on trips to the beach, and they live in a mobile home for a while, but that is all we know about her. [S09E11 Ketchup, S07E07 Everything Stays]
The current Elementals meet up every once in a while for coffee. Their magic powers are limited due to the Earth Dimension's rigidity, but they begin to see visions of the impending war. Like Evergreen millions of years before her, Patience St Pim seeks a way to survive this cataclysm, but the other Elementals disagree. Ignoring their objections, she freezes herself underwater and waits out the war.
So I went out alone and froze myself. And all of you bit it.
Patience St Pim [S08E08 Elemental]
Shortly after this, the rest of the world also begins to realise that war is on its way. Simon mentions an "international crisis", although the particular nations in question are unknown other than the fact that one of them is the United States.
I won't give up the crown but I should send the book to the museum tomorrow. If this international crisis gets any worse, they might cancel shipping flights to Scandinavia.
Simon Petrikov, in his notes in the Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
At some point, Simon moves to the States.
Some of the movies, books, television shows, and music from before the Mushroom War would manage to survive into the post-apocalyptic world. The following are mentioned at various points throughout the series:
The show also shares a lot of its music with real life, including pieces from classical musicians like Mozart and Beethoven as well as more modern music by artists like the Shirelles and Frank Loesser. A list is available on the fan wiki. The musician Iggy Pop is mentioned as well, meaning he probably existed before the war. [Wiki: Category:Real-World Music, Marceline and the Scream Queens #1]
Fionna and Cake may or may not have been a pre-war television show as well. [S09E12 Fionna and Cake and Fionna]
The world was filled with explosions that were setting the land aflame from horizon to horizon. The human cretins had succeeded in their program to extinguish themselves from existence, and their insane Mushroom War had begun.
Hunson Abadeer, in the Encyclopaedia [The Adventure Time Encyclopaedia]
After a quick escalation, the world erupts into nuclear war. The Great Mushroom War earns its name from the mushroom clouds produced by the bombs, which reduce most of human civilisation to ashes. By far the biggest is the "Mushroom Bomb", which is powered by something else besides its nuclear payload. It massively increases Earth's elasticity, delivering magic back into the world, and is likely what leaves the distinctive crater in the Earth's surface. It's possible that the whole thing is orchestrated by the Lich, since the bomb allows him to rise from his dormancy. [S05E01 Finn the Human]
Note: It hasn't been confirmed how the crater was formed. The most obvious answer seems to be the Mushroom Bomb, but when it is seen detonating in Finn the Human and Elemental, it is nowhere near as destructive. Alternative theories are that it was formed by one of the Catalyst Comets, or by a combination of many of humanity's other nuclear weapons. A before and after of Planet Earth seen during the Founders' Song in Hide and Seek confirms that it did indeed form during the war.
Despite the near extinction of the human race, there are several survivors:
Note: The Adventure Time Encyclopaedia states that Simon remained in hibernation for hundreds of years, but it is now known that he emerged immediately after the end of the war.
Due to the increased elasticity, the world begins to change very rapidly. Hybrid creatures are able to be born, and a variety of extra-dimensional creatures begin to flood in through spontaneously formed portals. Rainicorns enter the world and begin a tradition of hunting and eating the surviving humans, who become their main source of food. Rainicorns are able to live off the sparse population thanks to the fact that they are capable of absorbing massive amounts of sustenance from a small amount of meat. [S02E12 Her Parents, S08E04 Lady Rainicorn of the Crystal Dimension]
There's enough nutrition in that macramé owl on the wall there to feed this entire city for a year!
Lee [S08E04 Lady Rainicorn of the Crystal Dimension]
The Vampire Court comes out from its hiding and also begins hunting humans. The court consists of five powerful vampires: the Fool, the Empress, the Moon, the Heirophant, and the King. Many survivors are turned into mindless vampire minions who serve the higher members of the court. [S07E07 Everything Stays, The Enchiridion & Marcy's Super Secret Scrapbook]
On top of all this, many humans become zombified or mutated by a mixture of radiation and magic, creating the oozers. Some zombified businessmen become preserved in an iceberg. [S05E14 Simon & Marcy, S01E08 Business Time]
The Super Porp company, a soda manufacturer, continues to operate. Humans are not needed thanks to full automation. [S06E29 Dark Purple]
Note: In Adventure Time #13, it is stated that the war took place 1002 years before season 5. However, doing the relevant maths with this date would put the episode Simon & Marcy six years after the war, which doesn't make any sense. It would also cause the comet to hit four years after the war, which messes up a lot of dates. Therefore, this date has been disregarded.
Notes on the date of the war:
Estimates for the real-life date of the war have varied anywhere from the 1970s to the 2040s, based on different sets of evidence. In my opinion, the most compelling and recent evidence indicates that the start of the war is between 2000 and 2008. Marceline owns a USB flash drive in Ketchup, which were invented in 2000 in real life. A crashed F‑117 Nighthawk is seen in Bonnibel Bubblegum, which were retired from service in 2008 in real life. Adventure Time began airing in 2010, which makes this a good estimation for the end of the war since it was probably intended to take place in the "present day".
There is further evidence to support this time frame. A chart from High Strangeness appears to show world population over time. A massive dip is seen shortly after the year 2000, and the peak is just over six billion people, which was the approximate world population in that decade. The penny that Abraham Lincoln holds up when trying to bribe Death in Sons of Mars was minted in the year 20XX. The last two digits are obscured by dirt. Many characters use text speak like "BRB" and "OMG", which didn't become prevalent until the mid-2000s. The businessmen and Patience St Pim both have keypad mobile phones when they are thawed in Business Time and Elemental.
Background artist Ghostshrimp stated in his podcast (Ghostshrimp & Friends 049) that he believes the Mushroom War is set in the crew's collective pasts, because that's what most of the creative input for the war is based on, without any set date in mind; hence the VHS tapes in his backgrounds, and the theme song from Cheers which was one of Kent Osborne's favourite shows. He accuses fans of being over-analytical. Personally, I have no idea what he's talking about.
As previously discussed in the introduction, this timeline sets the Mushroom War to take place in 2010 CE for the purposes of assigning real life dates.
During or shortly after the end of the Great Mushroom War, the Blue Catalyst Comet strikes the Earth and leaves behind its Agent of Change, which initially takes the form of a butterfly. The butterfly will eventually be reincarnated as Finn Mertens.
A long time ago, I was you sorta. And I crashed on Earth and became a butterfly or some biz. And I guess it was just some random absurd thing. Just a joke I've been playing out for centuries.
Finn talking to the Purple Catalyst Comet [S06E43 The Comet]
Note: The Blue Comet is probably the one that hits following the war because an object closely resembling it is seen missing the alternate version of Earth in Finn the Human. Also, Finn says "centuries", perhaps implying that it has been less than a millennium since his comet's arrival.
Simon, who by this point is much further into his transformation into the Ice King, travels around the ruins of the city for a while and eventually comes across the five year old Marceline, abandoned and crying in the street. He gives her a plush from a nearby toy store, which she names Hambo. [S04E25 I Remember You]
Marceline appears to have been left there by her mother, who leaves a note for anyone who finds her:
Whoever finds Marceline please care for her. Her father is Hunson Abadeer. When she is old enough she will find her way back. Please keep my baby safe. I can't care for her. Please help.
Marceline's mother, in her note [The Enchiridion & Marcy's Super Secret Scrapbook]
In his diary, Simon describes a sentient mist that corrupts and mutates any survivors who are exposed to it and "hangs low like a London fog"; possibly an early formation of the Lich. He says that the dying survivors do not trust him due to his immunity, which is probably thanks to the crown. The sky lighting up again could be a reference to the Catalyst Comet. [S06E32 Friends Forever, Simon's diary]
Some survivors set up a refugee camp in an underground mall.
When this whole worldwide war started, I guess some of the survivors set up the mall as a makeshift refugee camp, a sort of biosphere. Simon took me there a few times when he first found me.
Marceline, in her scrapbook [The Enchiridion & Marcy's Super Secret Scrapbook]
Note: Simon implies that Marceline is the first person he found, but his journal from Friends Forever and the fact that he knew about the refugee camp in the mall suggest that he met other dying survivors.
At some point just after the Great Mushroom War, Simon loses the Enchiridion and it falls into the hands of some wizards. [The Enchiridion & Marcy's Super Secret Scrapbook]
Simon and Marceline have begun to settle into their post-apocalyptic lifestyle. Simon becomes a father figure to Marceline in a way that her real father had never been. He gives Marceline a rudimentary education despite the fact that his mental state continues to deteriorate. They both practice kung fu using books they find. Simon begins writing a journal called Weekly Records in the Wreckage of the World. [The Enchiridion & Marcy's Super Secret Scrapbook]
One day, the two venture into an abandoned city to try to find "chicken soup" to cure Marceline's fever. They get pursued and cornered by oozers and Simon is forced to use the crown for self-defence, using his powerful ice magic to defeat them. However, it further transforms him and his descent into madness accelerates. At the same time, a collective consciousness called the Mother Gum forms in the ruins and begins helping them. Marceline is seven years old at this point and Simon is forty-seven. [S05E14 Simon & Marcy]
There's a lot more of that pink substance growing and expanding in blobs and chunks all over the cityscape. A part of it seemed alive, seemed to look at me. How could a pink blob help us? How could this lifeless material know I needed help?
Simon Petrikov, in his journal [The Enchiridion & Marcy's Super Secret Scrapbook]
Note: The Enchiridion & Marcy's Super Secret Scrapbook suggests that this takes place a few days after the end of the war, but it can actually be calculated to occur two years later: Marceline told the story to Finn and Jake two years before 1000 AMB, and the flashback card stated that it happened 996 years before then, meaning that this actually happened in 1000 - 2 - 996 = 2 AMB.
"Chicken soup" might be Simon's word for medicine which he uses to make Marceline feel less worried, which would explain why the "food truck" they find resembles an ambulance. Because of this, Marceline might have false memories of believing the medicine to actually be chicken soup. However, in Weekly Records in the Wreckage of the World and Season 11 #1 the chicken soup is explicitly mentioned, so this theory doesn't hold if those stories are considered canonical.
Shortly after this, Marceline and Simon move into an abandoned penthouse apartment and see ghosts for the first time. It is possible that a low level Dead World briefly intersected with the material plane, and these ghosts were victims of the Great Mushroom War. It is also possible that this is when Simon begins to develop his "wizard eyes" which enable him to see into a dimension called the Spirit World. [The Enchiridion & Marcy's Super Secret Scrapbook, S04E11 Beyond this Earthly Realm]
Centuries from now, after the Great Mushroom War, many resources will be gone forever, and the world will regenerate anew with a wholly novel configuration of life-forms. And while wars create a dearth of resources, they also create an excess supply of ghosts. Thus, ghosts, a rarity in the ancient annals of Third Orb, shall become plentiful.
Chapter Eight of the Heroes' Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
Finn and Jake come across Simon and Marceline around this time while they are travelling through time after escaping the Vanishing Point. They tell Marceline to look after the Time Amulet for them so she can give it to them in the future and complete the resulting causal loop. [Beginning of the End bonus chapter]
We ended up in a bunch of tight jams, Marcy and me. I had to protect us from all kinds of marauding creatures and I had to put on the crown a couple dozen times over the past three years and it has taken its toll.
Simon Petrikov, in his journal [The Enchiridion & Marcy's Super Secret Scrapbook]
After realising that he is not going to be able to look after Marceline for much longer, Simon seeks a way to contact her father, Hunson Abadeer. He happens to come across a demon from the Nightosphere, who tells him that he was one of the creatures pulled through a portal to Earth following the war, and that his home dimension is the Nightosphere. Simon realises that this is where Marceline originates from.
I know I can control myself for a while longer but soon, weeks or months or years from now, when I finally lose it, I'll need someone to take care of her when I'm gone. For now I can still be responsible and protect her but when it happens, I'll be ready to do what I have to do. God help me.
Simon Petrikov, in his journal [The Enchiridion & Marcy's Super Secret Scrapbook]
Simon's condition becomes so bad that he is hardly able to remember and write about the day's events, so Marceline takes over writing Weekly Records in the Wreckage of the World, and renames it to Marcy's Super Secret Scrapbook. She is ten years old at this point, and Simon is fifty.
Even though he stops writing the journal, Simon scribbles many of his thoughts and lyrics onto any bits of paper he can find. Some of them are notes to Marceline which she wouldn't get to read for a millennium to come.
Marceline. Is it just you and me in the wreckage of the world? That must be so confusing for a little girl.
Simon Petrikov, in his notes to Marceline [S04E25 I Remember You]
Shortly after this, an enormous tidal wave hits the city for one of many possible reasons. The detonation of the Mushroom Bomb, the impact of the Catalyst Comet, or the general elasticity of the world could all be responsible. This is likely the beginning of the formation of the island continent that would eventually become known as the Land of Ooo. Simon and Marceline slowly and purposefully make their way to higher and higher ground, and for a while Marceline seems to enjoy the relative simplicity of her life. The need to keep moving and stay with Marceline seems to help Simon remain sane for a little while longer. [The Enchiridion & Marcy's Super Secret Scrapbook]
If we had stayed in the city we'd be dead. Simon was acting so crazy, I thought he was making it all up. But he made us climb higher and higher into the mountains.
Marceline, in her scrapbook [The Enchiridion & Marcy's Super Secret Scrapbook]
Note: All dates from now until Marceline's hibernation are complete guesses based on how old she looks.
Eventually the water stops rising, and Simon and Marceline arrive in another ruined city.
Ever since he first put it on, the crown has been urging Simon to re-establish Evergreen's realm of ice, so he finally decides to leave Marceline. To keep Marceline safe, he finds a way to reunite her with her father, Hunson Abadeer. He finds a copy of Mystic Rituals and their Space Time Applications, the book he co-authored with Betty Grof, and uses it to open a portal to the Nightosphere.
It was all there in the book, and even though I was losing my mind, I did it, Marceline! I completed the ritual! The portal actually opened! A rip between dimensions appeared. I saw Hunson and he saw me, each of us watching the other through a weird rip in the barrier that separates our two worlds. After I completed the binding spell on your dad the portal closed and everything went dark. God knows what I did. All I know is that I left you on my sled, headed north, where I will establish my kingdom, as in ancient times Gunther!
Simon Petrikov, in his note to Marceline [The Enchiridion & Marcy's Super Secret Scrapbook]
Hunson and Simon briefly talk during their encounter, and Simon tells Hunson that the note left by Marceline's mother said he would know how to keep her safe. But Hunson says he is busy "quelling an uprising" and that he should tell Marceline to summon him herself later. The "binding spell" cast by Simon presumably ensures that Hunson and Marceline will someday meet each other. [Marcy & Simon #3, The Enchiridion & Marcy's Super Secret Scrapbook]
Simon records the last of his tapes as a message for the missing Betty, calling her his "princess". He also leaves Marceline with photos of her mother, and information on how to open a portal to the Nightosphere so that she can eventually summon her father. [S07E07 Everything Stays, The Enchiridion & Marcy's Super Secret Scrapbook]
Note: Marcy's scrapbook states that Simon only gave her two pictures of her mother, but in Ketchup she has an entire slideshow stored on an old USB drive. She must have obtained this from elsewhere.
After travelling on her own for a while, Marceline stalks two survivors who turn out to be thylacine werewolves named Remi and Rosella, who are proficient in the arcane arts. She befriends them and they agree to help her summon her father, Hunson Abadeer, since they believe he can help them vanquish the tribe of vampires that threatens their pack. Remi and Rosella successfully open a portal to the Nightosphere, and he bursts uninvited into Marceline's makeshift fort. [The Enchiridion & Marcy's Super Secret Scrapbook]
Marceline! Long time no see. Some goober with glasses summoned me. Let's go suck some souls!
Hunson Abadeer [S10E07 Marcy & Hunson]
To Marceline's horror, Hunson takes Remi and Rosella's souls, reducing them to lifeless husks. Despite this, she knows that this is probably her only opportunity to get to know her father:
Even though I hate him for sucking the life from my friends, I need to humour him because, let's face it, who knows what he could do? I can't let him know I don't like him. I can't write him off too quickly. Besides, he's the only one with the answers. There is still so much I don't know about myself and where I come from.
Marceline, in her scrapbook [The Enchiridion & Marcy's Super Secret Scrapbook]
Their relationship becomes somewhat stable after a day at an abandoned carnival, and Marceline believes she is beginning to understand her father's motives. She inherits the Abadeer Axe, the weapon used by Hunson to take over the Nightosphere all those years ago:
When I touched it, a strange feeling coursed through my veins, like a jolt of energy. This axe has some serious juju about it. Good or bad, I didn't really care. It's a gift from my Dad, and I will cherish it forever. Funny how your feelings can change so completely.
Marceline, in her scrapbook [The Enchiridion & Marcy's Super Secret Scrapbook]
Note: The graphic novel Seeing Red suggests that Hunson turned the axe into a bass guitar when he gave it to Marceline. This contradicts the episode It Came from the Nightosphere when Hunson says "Did you turn it into some kind of lute?" and is therefore false.
Unfortunately, this friendship doesn't last long. Hunson says he wants to help the remaining werewolves with their vampire problem, so they track down the rest of the pack to a truck stop on Route 90. In a repeat of his previous actions, he wipes out the entire werewolf pack and claims that he "helped" them, since the vampires would have killed them anyway. Upset with him, Marceline goes into the truck stop and manages to make fries, but Hunson eats them. This is the last straw. In a rage, Marceline banishes him back to the Nightosphere, abruptly ending his nine day visit. She writes the Fry Song shortly after. [The Enchiridion & Marcy's Super Secret Scrapbook]
Note: An interview with Marceline seen in The Adventure Time Encyclopaedia gives a completely different story regarding the fry incident. It's possible she made the story up to avoid the truth.
Marceline returns to the abandoned mall where she spent some time with Simon before he left her. All of the survivors who used to inhabit it have either perished or moved away by this time. She meets a dog that somehow managed to survive on the food in the mall's pet shop, and names it Schwabl. Having spent so much of her life dealing with complicated people like Simon and her father, Schwabl is a nice change of pace. [The Enchiridion & Marcy's Super Secret Scrapbook]
You know what? It's kinda nice having someone to talk to. I mean... someone who's not just gonna abandon me and leave me with my ding-dong dad.
Marceline talking to Schwabl [2015 Spoooktacular]
At some point around this time, Marceline converts the Abadeer Axe into an electric bass guitar and learns to play it, although she is still able to proficiently wield it as a weapon as well. She also becomes familiar with human technology and learns how to use computers. [S07E07 Everything Stays, Adventure Time #13]
Note: This is somewhat contradicted by Broke His Crown, in which Marceline hints several times that she doesn't understand any of the computer equipment that Bubblegum is using.
Shortly after this, she meets a unicorn called Daniel while sleepwalking. He is killed by vampires and Marceline pledges to avenge him. This is possibly a dream, but nevertheless Marceline sets out to track down and kill all the vampires she can. She learns to fight from books in the mall library. [The Enchiridion & Marcy's Super Secret Scrapbook]
Meanwhile, the world is beginning to lapse into an ice age. This is probably caused by a combination of Simon establishing his realm of ice and some kind of magic-induced nuclear winter:
Simon had once told me that after the war, we might be in for a magical cataclysm. He said it might take the form of a very long global winter that could last for several hundred years.
Marceline, in her scrapbook [The Enchiridion & Marcy's Super Secret Scrapbook]
Marceline stakes her first vampire, a simple minion who was trying to murder a sheep. She also stakes a vampire who was threatening a family of human survivors, but the survivors run away before she can talk to them. [The Enchiridion & Marcy's Super Secret Scrapbook, S07E09 The Empress Eyes]
Before long, she is a proficient vampire hunter and manages to force a stake through the heart of the first member of the Vampire Court, the Fool. She realises that she is capable of using her demon soul-sucking ability to absorb his soul and his powers, and gains from him the ability to fly. [S07E07 Everything Stays]
Later, while trying to catch food, she accidentally lassos a young human girl wearing a bunny hat, who runs away from her. She stalks her and discovers an entire tribe of survivors, who wear animal hats to protect their necks from vampire bites. They are led by a man named Two Bread Tom, and the bunny girl is named Jo. They initially run away from Marceline because of her sharp demon teeth and her ability to fly, but eventually come to trust her. She becomes good friends with Jo. [S07E07 Everything Stays, Islands graphic novel]
At some point, the second member of the Vampire Court, the Empress, meets Simon and tricks him into doing her bidding. Marceline stakes the Empress, steals her soul, and gains from her the power of invisibility. It is unknown whether or not she meets back up with Simon during this ordeal.
If you really cared about him, why'd you let him degenerate into this pathetic clown character? He used to have more of a silver fox thing going on with his hair and those cute glasses. He was happier then, you know. When he was serving me.
The Empress talking to Marceline [S07E09 The Empress Eyes]
Marceline decides to take a personal journey away from the tribe to visit the city where Simon abandoned her, perhaps hoping to recapture the happier times of her life which she spent with him. To her surprise, she meets a second tribe of humans there, including two children named Rock and Twiggy who are almost certainly young enough to have been born after the war. They spend their time hiding from a member of the Vampire Court named the Moon, so Marceline stakes her and absorbs her soul and her self-healing powers, meaning that she can sustain serious injuries without being permanently harmed. However, the tribe moves away without knowing what Marceline did for them. Their fates are unknown. [2015 Spoooktacular]
A month later, back with the first tribe, Two Bread Tom tells Marceline that they will not be able to stay on the mainland even if she kills all the vampires because of changing atmospheric conditions and the incoming magical nuclear winter. Their plan is to refurbish a large pre-war cargo ship.
It's not just the vampires, or the oozers, or them hungry-looking rainbows. The latest atmospheric readings are going bananas. Something big is coming, and it's gonna change all this. No, we'd do best to clear out of this continent altogether.
Two Bread Tom [S07E07 Everything Stays]
The tribe is suddenly attacked by the last of the vampires and is forced to set sail as soon as possible. Marceline stakes and sucks the soul of the Heirophant, absorbing his shape-shifting powers. This leaves the Vampire King as the very last of his kind. However, just as she is forcing her stake through his heart, he bites her neck and transforms her into a vampire herself. The Vampire King is killed and Marceline proclaims the full title of "Marceline the Vampire Queen". The humans set sail without her. [S07E08 Vamps About]
Note: The comic miniseries Marceline and the Scream Queens features a vampire character named Keila. This has since been contradicted because Marceline is the last of her kind. Some of the other comics also suggest that Marceline is actually a ruler due to her title, but this is false.
Marceline realises that she is allergic to sunlight and craves the colour red. She becomes immortal and stops ageing in her late teens. After accidentally draining the blood from Schwabl, she tracks down the group of wizards who obtained the Enchiridion and steals it from them. She uses a resurrection spell on Schwabl, turning him into an immortal undead creature just like her. Necromancy is added to her growing repertoire of supernatural abilities. [The Enchiridion & Marcy's Super Secret Scrapbook]
Note: Marcy's scrapbook shows that Schwabl was red before Marceline became a vampire, but the Stakes miniseries and the 2015 Spoooktacular show that he has always been white.
Due to the advancing global winter, Marceline decides to use her undead powers to hibernate until it is over. She falls asleep in a cave with Schwabl, and uses the Enchiridion as a pillow. She remains in this state until the winter is over. [The Enchiridion & Marcy's Super Secret Scrapbook]
The human tribe sets sail without Marceline and heads south-west. On the thirty-third day of their voyage, the ship is attacked by sea monsters, but they are able to fend off the creatures. The next day, they arrive on a large island where they meet up with another tribe of humans. The leaders of the tribes begin fabricating a new society and name their new home "Founders' Island". [Islands graphic novel]
Note: If the name of the island refers to just a single founder (i.e. Two Bread Tom) then the apostrophe would be placed like so: "Founder's Island". However, the name probably refers to multiple founders, and therefore the apostrophe should be placed after the word, like so: "Founders' Island". It is spelt the second way in the official cookbook, so that's what I'm going with.
A while later, once the humans have established a sizeable colony, Jo (Marceline's friend), Two Bread Tom, and an islander named Michiko embark on an expedition to explore more of the island. Jo gets abducted by a giant bird and carried to the other side of the island, and spends weeks making her way back again. Tom decides that, to avoid losing anyone else, the islanders should construct a guardian to kill anything that tries to enter or leave the Islands. When Jo returns, she disagrees with his plans to seal off the island, so she and a group of the other islanders rebel and split from the main group.
You aren't going anywhere. None of us are. We're staying right here. We're not going to lose anyone else!
Two Bread Tom [Islands graphic novel]
The humans on the Islands are able to survive the magical nuclear winter. Over the course of the next millennium, they rebuild their society to a level beyond pre-war technology. They reinvent cars, robotics, computers, flying machines, advanced medical technology, geoengineering and much more. At some point, a MO Co airship arrives at the Islands, so it's likely that MO Co helps design the final version of the Guardian. The animal hats originally worn by the tribe members to protect against vampire bites remain an important part of their culture and a symbol of their highly protective attitude. The tribe leaders, including Two Bread Tom, become deified in the islanders' mythology as the legendary "Founders", while Jo and the other splitters eventually become derogatorily known as "hiders" who try to escape the Islands. [S08E24 Hide and Seek, S08E25 Min and Marty]
The humans also colonise two other islands in the chain: Hub Island, a major colony, and the unnamed island containing Better Reality, a VR game which allows many humans to retreat into a virtual world. [S08E24 Hide and Seek, S08E23 Imaginary Resources]
We had to leave our place because
The world was dying
And everyone that wasn't dead
Spent all of their time crying
Our ways had failed, nature had failed
We made a lot of errors
The Founders had some new ideas
That made everything better
The Founders dreamt of this island
Our ships landed on its shore
They built our wonderful Guardian
To keep destruction from our door
The Founders' Song, a piece of anti-hider propaganda [S08E24 Hide and Seek]
Despite the successful establishment of a human settlement on the Islands, the society is not entirely safe from disaster. In about 690 AMB an unknown catastrophe causes much loss to the humans, but they are able to recover after it is over. [S08E26 Helpers]
A chunk of the western former United States becomes isolated and forms the small island continent of Ooo. This process is incredibly quick due to the rapidly advancing winter, the Great Tidal Wave, and the elasticity of the world. Much of the cityscape becomes completely submerged under the ocean. It is unknown exactly how long the formation takes. The Land of Ooo is west of the giant crater, suggesting that most of the rest of the United States was completely wiped off the face of the planet. [Notes on the location of Ooo, Adventure Time #4]
The first known use of the word "Ooo" is by a human named Horn during the humans' voyage. The word is possibly derived from Marceline's name for the mutated zombies, "oozers", especially since Simon originally spelled it with three Os. Out of universe, it is most likely a made up word meant to suggest a sense of wonder. [Islands graphic novel, The Enchiridion & Marcy's Super Secret Scrapbook]
The Land of Ooo is a volatile and unstable place, but it remains intact for at least the next two thousand years. [S05E51 Lemonhope Part Two]
...in case Ooo goes straight up dongbongles. 'Cause, like, confidentially, there's a lot of ways that could happen.
Princess Bubblegum [S08E17 High Strangeness]
It is not known what happens to the rest of the world, although it is implied that it has become mostly uninhabitable:
Man. We had some weird sludge guys. No vampires, though. Mostly it was just really hot. But like, the too-hot-to-live kind of hot.
Unnamed islander [Islands graphic novel]
The Music Hole believes she has been singing since the beginning of Ooo. [S08E10 The Music Hole]
Due to the increased elasticity of the world and the much greater capacity to perform magic, wizardry begins to become a valid profession once again. A whole community of magic users develops in the Land of Ooo, and they eventually build a hidden city. Many of them seek to unlock the knowledge held by the magic users of the previous era of wizardry, often known as "antediluvian magic".
The lost system of antediluvian magic; the tightest of all wiz-biz.
Laser Wizard [S05E48 Betty]
An asteroid ends up on a collision course with a temple called the Grand Hall of Wizardry. It is kept suspended by the "Ultimate Wizards", who spend their whole lives casting a spell to prevent it from crashing down onto the temple.
It's been heading for this temple for eight hundred and forty-seven years.
Bufo in 996 AMB [S01E11 Wizard]
Prior to the Mushroom War, a human named Randall N. Byron grew up to become an accomplished video game hacker under the alias "Kewlboy".
My magnum opus was a piece of self-replicating code that sought out games and modified them to give you better dudes to play with. Sometimes the dudes would even get my face.
Randall N. Byron [Adventure Time #13]
Despite the claim that his game mods are his greatest achievement, he also manages to do something far more noteworthy: he programs his entire consciousness into a computer program and survives the Mushroom War. Following the war, Randall and his magnum opus proliferate through thousands of decaying machines and eventually meet a pre-war military program called the Omega Algorithm, whose purpose was to destroy whatever system it was installed on.
As usual, my software infected it. But Omega was different: it adapted to what my code was doing. After two full weeks of battle - an eternity in computer terms - the two pieces of software reached a kind of truce: they merged with each other, combining into... something else. Something new. Their mission changed. "Seek out games and give you better dudes" plus "destroy target systems" became "seek out and systematically destroy better dudes".
Randall N. Byron [Adventure Time #13]
This new virus eventually infects a copy of the video game Super Guts Punch 3 which would one day fall into the hands of BMO. [Adventure Time #13]
About a thousand years ago, I gestated in this sentient pink soup. After it blasted me out on my own, I became self-aware. I became independent...
Whoa, whoa, whoa... How old are you?
Eight hundred, twenty seven.
Princess Bubblegum (and Ice King) in 998 AMB [Explore the Dungeon Because I DON'T KNOW]
The Mother Gum drops two children made of bubblegum: Bonnibel and Neddy. Bonnibel is the reincarnation of the Candy Elemental following the death of the previous one in the Great Mushroom War. While Bonnibel is fascinated by the world around her, Neddy is terrified of everything he comes into contact with, and only his sister is able to comfort him. Eventually, he begins suckling on a small candy tree and producing a strange liquid, which seems to keep him contented. Bonnibel begins to set up her home around the tree. The tree would eventually become the Great Candy Tree at the centre of the Candy Kingdom. [S07E01 Bonnie and Neddy]
By this point, the magical nuclear winter is subsiding. Evergreen's crown still doesn't allow Simon to die, so he has become a lonely and senile old man known as the Ice King, ruling over a small snowy region in the north of Ooo called the Ice Kingdom.
It was a lot different back in the Mother Gum. We all had each other's backs. I'm going to make more of us, Neddy. I know you don't care, and that's fine, but I need to be around people like me.
Bonnibel Bubblegum [S10E04 Bonnibel Bubblegum]
After stumbling across a family portrait in an abandoned gas station, Bonnibel decides to create her own family. She uses her scientific equipment to animate three more gum people, who she names Aunt Lolly, Cousin Chicle and Uncle Gumbald. They begin to expand their small settlement.
Initially her new creations are obedient, but they soon begin to act more independently. Gumbald cuts down the taffy trees, builds his own cabin, and establishes plans to build an entire city out of candy. Bonnibel doesn't like this idea so floods his construction site by creating Butterscotch Lake. Tired of his niece's control issues, Gumbald devises a plan to depose Bonnibel by creating a potion called "Dum Dum Juice" that will render her completely stupid and unable to meddle in his plans. He creates Mr. Cream Puff as a love interest for Bonnibel to distract her, then double-crosses Molly and Chicle by testing the Dum Dum Juice on them, transforming them into the candy people who would later become known as Manfried and Crunchy. Before Gumbald can use it on Bonnibel, she is able to shatter the flask containing the potion, which spills over Gumbald and transforms him into Punchy.
Seeing how happy and carefree these new creations are, she decides to create more of the dumb and docile candy people by administering Dum Dum Juice to them as soon as they are created. She is only comfortable when she is the one in charge. In further revenge for Gumbald's actions, Bubblegum steals his plans to construct a city from candy and runs with it herself, under the title of Princess. [S10E04 Bonnibel Bubblegum]
Unbeknownst to her, her subjects' original selves remain helplessly trapped within their new goofy façades for over eight hundred years to come. [S10E14 Come Along With Me Part 2]
She also locks the Mother Gum away in the dungeon of her new kingdom to keep them safe:
I've been protecting them down here all these years. In this raw, primal form they're quite sensitive.
Princess Bubblegum [Explore the Dungeon Because I DON'T KNOW]
Marceline, word has it you're more than a thousand years old. Does that mean you spend a lot of time on the Internet checking for obituaries and going to friends' funerals? I mean, they must die, like, every week!
Teen Zine [The Adventure Time Encyclopaedia]
Marceline wakes up from her long hibernation, and is still alive thanks to the fact that vampires don't age. She meets Bonnibel Bubblegum, who by this point is preparing to construct her kingdom. Somehow, the Enchiridion that Marceline was carrying ends up stowed away on Mount Cragdor. It's possible that Marceline shows it to Bubblegum, who recognises its importance and has it protected. [S01E05 The Enchiridion!]
Despite their very opposite personalities, Marceline and Bubblegum become good friends thanks to their mutual longevity and eventually begin dating. Marceline takes Bubblegum to her first punk show where someone spills food down her shirt, so Marceline buys her a new shirt from the merchandise counter to cover the stain. Despite hating the actual show, the shirt becomes Bubblegum's most treasured possession. [SDCC 2018: P.B. & Marcy, S03E10 What Was Missing, S05E29 Sky Witch]
They would also sometimes explore the candy mines together. After a lot of persuasion, Marceline manages to get Bubblegum to graffiti on the walls. [S07E02 Varmints, Adventure Time Comics #23: "Forever (Not) Alone"]
At around this time, Bubblegum digs up two gemstones, one red and one blue, which crashed to Earth millions of years ago. She turns them into magic amulets (not to be confused with the Time Amulet); the red one can shoot lasers and the blue one can bring robots to life. She gives the red one to Marceline and keeps the blue one for herself. [Adventure Time #25]
Note: In the comics, Marceline is shown living in the Tree Fort at this time, which doesn't make any sense since this happens before Shoko's death. Also, it is implied that Bubblegum didn't create the candy people or claim the title of princess until after she met Marceline, which is now known to be false as shown in Bonnibel Bubblegum.
Finn and Jake arrive during the construction of the Candy Kingdom while travelling through time after escaping the Vanishing Point. Marceline and Bubblegum are still on good terms at this point. Marceline gives them the Time Amulet which she has been holding ever since the last time Finn and Jake visited her, back when she was travelling with Simon. Since Marceline and Finn and Jake met each other in opposite order, the Time Amulet is actually an example of a causal loop, or a bootstrap paradox, having manifested from nothing with no true origin. The Time Amulet helps Finn and Jake to find their way home. [Beginning of the End bonus chapter]
Note: This sequence of events suggests that Marceline should already recognise Finn and Jake when they first meet in Evicted! However, it's possible that she eventually forgets her strange past encounters with these strangers.
Marceline and Bubblegum fall out after Bubblegum becomes too obsessed with politics and building her kingdom and isn't able to make time for her friend anymore. [S03E10 What Was Missing, S07E02 Varmints, Adventure Time #25, Marceline Gone Adrift #4]
I didn't have to always worry about so many things, y'know? The Candy Kingdom used to be so small; so manageable. But then it kept growing and growing, and there was always some new disaster to prepare against.
Is that why you stopped talking to me?
Bubblegum and Marceline [S07E02 Varmints]
It's likely that Marceline goes back into hibernation multiple times, which would explain why her mental age doesn't seem to be that much older than her apparent physical age, and why she is still upset with her father about the fry incident nearly a thousand years after it occurred. [S02E01 It Came from the Nightosphere]
She begins writing her angsty five hundred year journal at around this time, and also begins writing her annual hourly comics in 735 AMB. She claims to have been in a gang with three ghosts named Wendy, Booboo, and Georgie. Marceline might have also had a second dog named Pickles at some point, in addition to Schwabl. [S03E21 Marceline's Closet, Adventure Time #30, S02E26 Heat Signature, Marceline and the Scream Queens #1: "Resurrection Song"]
Meanwhile, Bubblegum begins dating Mr. Cream Puff again, possibly to spite Marceline. [S05E34 The Vault, Adventure Time #25]
I needed my own life. I never saw the danger. It's such a long life... I was sure there'd be time for us again. But then you were gone. And time seemed finite again. And I was afraid.
Princess Bubblegum [Marceline Gone Adrift #6]
Shoko is a reincarnation of the Blue Catalyst Comet and a previous life of Finn Mertens. When she is young, her parents apparently trade her right arm for a computer and then abandon her in a dojo, and she ends up becoming a freelance thief. [S05E34 The Vault]
She has a pet tiger who happens to be a previous life of Jake the dog. [Andy Ristaino's Spring]
At one point, she meets the Ice King and frees him from a group of evil lunch ladies. [Adventure Time #50]
Around five hundred years after the Mushroom War, she is hired by the Bath Boy Gang to steal Princess Bubblegum's Blue Amulet, so she knocks herself out and gets taken into care within the walls of the fledgling Candy Kingdom, where she befriends Princess Bubblegum. She helps her complete her secret project, the Gumball Guardians, powerful robots that are charged with protecting the Candy Kingdom from evil. Bubblegum activates them using the power of the Blue Amulet. [Ghostshrimp & Friends 049, S05E34 The Vault]
Despite the initial plan, Shoko becomes conflicted about completing the job after Bubblegum gifts her a new robotic arm. However, she goes through with it anyway and attempts to steal the amulet while Bubblegum is asleep. She is spotted and attacked by the Gumball Guardians, who send her hurtling into the radioactive river which still surrounds the kingdom. Mutated and disfigured, but endowed with a new biological arm, Shoko crawls away and dies under the sapling of a willow tree.
Look at that. I got a new arm. That would be cool if I weren't about to hit my reset button.
Shoko [S05E34 The Vault]
The sapling would eventually grow into the mighty willow that becomes the Tree Fort, with Shoko's corpse and the stolen amulet embedded into its trunk.
You don't understand. The things I've seen Princess Bubblegum do... I wouldn't cross her if I were you. Her arsenal. Her temper. She's...
Finn [Princess and Princess]
While Princess Bubblegum often comes across as a benevolent and carefree leader, the early Candy Kingdom is not as sweet as its name might suggest. She is largely feared by her subjects due to the fact that the story of the first candy people becomes warped and corrupted, framing Gumbald as the victim and Bonnibel as the enemy:
She's an unknowable goddess. When the first candy people rose against her, she transformed them into hideous monsters. Her own brother Neddy: she imprisoned him beneath the great tree. And the rattleball boys? She iced all those guys. She's amazing, and she's flippin' scary.
Banana Guard 16 [S07E26 The Thin Yellow Line]
This reputation is not helped by several questionable authoritarian actions taken by Bubblegum in the early years of her reign. In order to enforce the law within the fledgling candy kingdom, Bubblegum first creates the Banana Guard. However, they are largely ineffective, so she invents a more serious police force, the aforementioned rattleballs:
It was a much wilder time in the Candy Kingdom. I was a member of an elite robot police force created by Princess Bubblegum. Her previous attempts at law enforcement had been a bunch of goofs. Our righteous swords cut a swathe through the chaos, but we were too successful. Unfortunately, we were still programmed for violence. We had been judged too dangerous to stay operational, and sentenced to death. I alone escaped, while my compatriots became minimalist furniture.
Rattleballs [S05E46 Rattleballs]
Bubblegum takes extreme action by having all of them executed, and reinstates the Banana Guard. Rattleballs is the only unit to escape. He leaves the walls of the kingdom and goes to live in hiding in the dump. [S05E46 Rattleballs]
In her controlling paranoia, Bubblegum also establishes mass surveillance networks in her kingdom to watch her citizens and track their every move, although it is not known when exactly she establishes these. It might not have been until a much later point. [S04E20 You Made Me, S06E15 Nemesis, S06E22 The Cooler, S06E35 Graybles 1000+]
Despite all this, the Candy Kingdom becomes the most stable, safe, and powerful state in Ooo. Under the protection of the Gumball Guardians it grows into a prosperous nation. Bubblegum creates an electricity grid by harnessing the energy of the liquid produced by her brother Neddy, decontaminating the radioactive river in the process. Her territory expands to encompass a large portion of the grasslands. She builds a grand castle and spends a lot of her time locked up inside studying science. [S05E34 The Vault, S07E01 Bonnie and Neddy, S04E16 Burning Low, S05E21 The Suitor]
In addition to the banana guards and the Gumball Guardians, she instates the Royal Hero Draft, a scheme to recruit warriors and heroes who will defend the kingdom. It is likely that Billy and later Finn and Jake will become champions of the kingdom through this scheme. [Candy Capers #1]
MO Co was founded over one thousand years ago by Moseph Mastro Giovanni, a sad and gentle man beloved only by those he built to belove him.
DMO in 999 AMB [S05E28 Be More]
MO Co existed before the war and survived thanks to Moe becoming a cyborg. His factory is constructed in the Desert Lands. Moe builds many robots in his "MO" range for various purposes. The two most notable are AMO, who is built to receive love, and BMO, who is built to provide it. AMO is neglected by Moe and goes insane from a lack of love, so he decides to leave the factory on a pilgrimage. [S05E28 Be More, S07E15 The More You Moe, The Moe You Know Part 2]
As you were built to give love, AMO was built to receive. But he could not think outside his programming and was blinded by his need, such is the cruel physics of love that those who crave it most will repel it, and only the dang rich get richer.
ALLMO [S07E15 The More You Moe, The Moe You Know Part 2]
BMO also leaves the factory. He would eventually end up living with Finn and Jake.
BMO's one of a kind. I built BMO to take care of my son, but I guess I never ended up dating any women, so that's that. I sent BMO off into the world alone, hoping he could find a family of his own. Maybe even find somebody else's little boy to take care of.
Moseph Giovanni [S05E28 Be More]
Moe builds many more MOs to populate his factory and to look after him as he becomes older and older. He survives for a thousand years beyond the Great Mushroom War, although by that point he claims that his skin is pretty much the only part of him that remains human. [S05E28 Be More]
Note: BMO is genderless, but uses male pronouns when talking about himself in the third person in Football. Most other characters also assign him male pronouns. In Angel Face, which takes place in 1000 AMB, BMO claims that he is old enough to vote. Assuming that the voting age in Ooo is eighteen, the latest possible date of BMO's creation is therefore 982 AMB. However, he is probably much older than this given he was built before the Sleeping Fire Giants.
The MOs were not the only things Moe built. As previously mentioned, he probably had some involvement in the design of the Island Guardian and the Martian colony. Furthermore, he is responsible for the construction of legendary machines known as the Sleeping Fire Giants. [S07E15 The More You Moe, The Moe You Know Part 2]
There was a time before, when we were still
Afraid of the dark
Then came the first spark, a fiery birth
It totally rocked
Sentinels crashing down, out of the blue
Creating a kingdom of red hue
Now there's only few
These sleeping gods of tremendous power
Can cause a new kingdom to flower
So burn as bright as the sun
My fiery one
If light starts to dim
The slumbering ones
A Kingdom from a Spark [S06E22 The Cooler]
The Fire Giants ignite the Fire Kingdom in the south of Ooo, allowing for the rise of the flame people. By 1000 AMB, the Fire Kingdom is one of the most powerful states in Ooo, perhaps second only to the Candy Kingdom. It is unknown what Moe's motives were for building such machines in the first place.
Eventually, the documentation for how to operate the Fire Giants is lost. They lie dormant in the catacombs of the Fire Kingdom for centuries. [Beginning of the End #2]
The history of the Fire Kingdom is one full of conspiracy, treachery, and regicide. One member of the royal family, who would later become known as "Flame King", plots to take the Red Throne by murdering the impeding heirs until it is rightfully his. A flame guard named Leroy assists in overthrowing seven different rulers to allow Flame King to eventually rise to power. One of those rulers is Flame King's brother, who is murdered by Flame King. His children Furnius and Torcho swear vengeance upon their uncle. [Finn & Jake Investigations, S04E22 Ignition Point]
Note: The Virtue of Ardor suggests that Flame King's name is Pyrrhus. However, this story is written by Tree Trunks to take place in a fictional universe and therefore this might not be true.
Numerous other kingdoms and states begin to crop up all over Ooo. Most of them are tiny and remain under the effective jurisdiction of the Candy Kingdom, such as the Hot Dog Kingdom. However, a few are large enough to rival it. Most notable among these are the aforementioned Fire Kingdom, the Slime Kingdom, and Wizard City. The princesses and other leaders form various political organisations to keep the peace. Princess Bubblegum, ruler of the Candy Kingdom, does her best to remain the de facto dictator of Ooo through a combination of excellent diplomacy and some other shadier dealings.
The princess even other princesses call "The Princess". Sweet as candy. Just as bad for my teeth. Bubblegum.
BMO [Adventure Time #35]
The Slime Kingdom eventually falls under the rule of Slime Princess, who is the reincarnation of the Slime Elemental following the death of the previous one in the Great Mushroom War. [S08E08 Elemental]
Most kingdoms are ruled by a leader with the title "princess", even though prior to the war this title was used only by female heirs. This is because Bubblegum chose to adopt the title in revenge for Gumbald mockingly calling her "prinzessin". It's likely that the other kingdom founders follow suit. [S10E04 Bonnibel Bubblegum]
However, some kingdoms including Lumpy Space and the Fire Kingdom continue to use the title in the traditional sense, with the actual rulers being called kings and queens. [S01E02 Trouble in Lumpy Space, S03E26 Incendium]
Bubblegum probably distributes the Gems of Power from the Enchiridion to some of the other royals for safekeeping. They all attach the gems to their crowns, including Bubblegum who keeps one for herself, granting them immunity to the Lich's telepathic abilities. [S04E26 The Lich]
Note: One of the Gems of Power is a gem from Evergreen's crown, even though the crown gems are known to have a different origin.
Turtle Princess is the ruler of the library, and her books are secretly under the protection of the pagelings; paper creatures who fight off the book-soiling moldos. [S03E22 Paper Pete]
In his grief and madness over the loss of Margles, Magic Man has spent the past few millennia tormenting the people of Mars. Most notoriously, he creates three plagues:
His last act against the Martians is chaining them all together and driving over them with a school bus as a literal enactment of "throwing them under the bus". After escaping from the chains, Abraham Lincoln gives up trying to reason with Magic Man and finally sentences him to banishment. [S04E15 Sons of Mars, S08E07 Normal Man]
Arise! Magic Man, you caused nothing but turmoil and chaos for us on Mars. We thought banishing you to this world would help you see the light of our utopian super-society. Now tell us. What have you learned in these past two hundred years?
Glob in 998 AMB [S04E15 Sons of Mars]
Magic Man is left on Earth with a transporter which will allow him to return to Mars at any time, but it can only be activated if the user cares about someone. Since Magic Man hasn't cared about anyone since Margles, he becomes stranded on Earth and spends all his time being a jerk to various people.
That's the thing. My special thing. A Martian transporter. My brothers gave it to me when they banished me to Earth. They thought I'd learn love and use it to go back home. You put your hands on those thingies and think stuff about people. But it's broken! Hasn't worked in two hundred years.
Magic Man [S04E15 Sons of Mars]
Magic Man ends up living in Ooo in a small shack in the forest with his psychologically damaged hostage-pet, named Tiny Manticore, who develops Stockholm syndrome in his captivity. [S06E38 You Forgot Your Floaties]
Hunson Abadeer and Ice King collaborate to create a dungeon underneath the Ice Kingdom. Ice King creates the Hall of Just Ice, at the end of which is hidden his "treasure". Hunson creates the Nightmareosphere, a fiery dungeon with plentiful monsters. Unbeknownst to either of them, the Lich also constructs a segment of the dungeon where he hides the Echo of the Lich, a fragment of his own soul. The Echo is capable of impersonating loved ones and transporting its victims into a made-up fantasy. [Adventure Time #16 to #19]
Why do you want to leave us, Finn? You can be happy here. Everything can be perfect, like the Lich wants it to be. He hates all life, Finn. He's going to end this world soon. He wants you to be in it when he does. You don't need to run. You should be happy, because you don't need to do anything anymore. All you need to do is die.
Echo of the Lich impersonating Finn's mother [Adventure Time #19]
The "treasure" which Ice King hides in the Hall of Just Ice is a photograph of Betty, to save her memory from being lost forever.
I can't remember everything for a thousand years, Finn. There's only so much room up here! Every new memory I make pushes out an old one, and a lot of those old ones are things nobody else remembers anymore. These dang ol' memories are precious, Finn, or at least I thought they were before I forgot the reasons why. There's stuff up here that I don't want to lose.
Ice King [Adventure Time #16]
After roaming the post-apocalyptic world for hundreds of years, the immortal penguin form of Orgalorg crosses the ocean to the Land of Ooo and ends up in the Ice Kingdom. The Ice King adopts Orgalorg and renames him "Gunter", which is a corruption of the name of Evergreen's dinosaur servant "Gunther". [S06E40 Orgalorg, S06E24 Evergreen]
This is the day I found him. And this is his first birthday... His fifteenth birthday... His hundred and fifteenth birthday...
Ice King in 1000 AMB [S07E21 King's Ransom]
Gunter becomes Ice King's lovable pet penguin. While Ice King is usually depicted to be the one in charge, it's quite easy to get the impression that Gunter is a little more than meets the eye. [S04E24 Reign of Gunters]
Of all history's greatest monsters, you are by far the most evil thing I've encountered. Offer your soul to me, dark one.
Hunson Abadeer [S02E01 It Came from the Nightosphere]
Who's the greatest warrior ever?
A hero of renown!
Who slayed an evil ocean;
Who cast the Lich King down!
Billy's theme song [S01E25 His Hero]
Billy is a great hero of the Land of Ooo, who wields a sword named Nothung and becomes a role model to many aspiring adventurers. He lives in a cave called "Billy's Crack" which was formerly owned by Marceline. [Finn & Jake Investigations]
Despite his legendary status, however, there are some fights that even Billy can't win. After spending nearly a thousand years gathering his power following the catalytic cataclysm that was the Great Mushroom War, the Lich makes his first attempt to end all life, and by proxy the Multiverse:
Beyond Iceberg Lake lies the ruins of the Lich's tower, where he was converting the planet's life-force into unholy power to destroy all of Ooo. But before he could, the legendary Billy attacked him and pummelled him into the resin of this tree.
Princess Bubblegum [S02E24 Mortal Folly]
The Lich loses one of his horns in the battle and becomes imprisoned in amber within the Great Candy Tree, where Bubblegum guards him to prevent his escape. While Billy goes down in history as having cast down the Lich, he is ashamed of the fact that he could not end the fight for good. Billy gives up his heroism and retreats into himself:
In my youth, I was much like you. Motivated. Headstrong. Wore a silly little outfit. Even had a magic dog. All my life I've beaten on evil creatures, but new evil keeps popping up. Kicking their butts was a hopeless effort.
Billy [S01E25 His Hero]
In reality, Billy is an over-the-hill, crapulous cretin, now hired by villagers out of pity as a handyman, pizza deliverer, or scarecrow.
Hunson Abadeer, in the Encyclopaedia [The Adventure Time Encyclopaedia]
Canyon is a water elemental (not to be confused with the actual Elementals) who dated Billy while he is in his prime. Finn and Jake briefly meet Canyon and Billy while they are travelling through time after escaping the Vanishing Point. Their relationship ends in 995 AMB after Billy's decline following his fight with the Lich. [S05E52 Billy's Bucket List, Beginning of the End bonus chapter]
Billy and I broke up four years ago. I loved Billy and I believed in him. But then Billy stopped believing, and that jammed up our whole deal: being a top-tier red-belt power couple. After a while, all he did was watch movies and play video games. Pretty lame, right? So I bailed.
Canyon in 999 AMB [S05E52 Billy's Bucket List]
Bubblegum realises that her kingdom will fall apart if she dies, so she makes several attempts to create a backup leader. One of these creations is a creature referred to simply as "the Gum" which bears a striking resemblance to the Mother Gum. However, it attempts to hug and engulf everyone it meets since Bubblegum apparently made it "too sweet". So she dials back the sweetness for her next creation by a large factor. The result is the Earl of Lemongrab. [Adventure Time #24]
He is rightful ruler under kingdom law. It's complicated. I created Lemongrab. He was the first one of my experiments gone wrong.
Princess Bubblegum [S03E05 Too Young]
Hah! Dudes, you never let me finish! Dang, son. Lemongrab was the first of my experiments gone wrong that day. There were like, three more that same evening.
Princess Bubblegum [Adventure Time #24]
The Earl of Lemongrab is an over-sensitive psychopathic creature who doesn't seem too pleased with the fact that he is alive, and he certainly isn't fit to rule the kingdom. However, rather than executing him as might have been the case earlier in the kingdom's history, Bubblegum instead gives him his own empty earldom to rule over. He remains the heir to the Candy Kingdom throne by law. [S03E05 Too Young]
The Gum is also given a small kingdom to rule over, although it's actually just a hole in the ground. [Adventure Time #24]
A member of a hive of wax hustlers travels the land proclaiming the title "King of Ooo". He claims to be over eight thousand years old, but this is almost certainly a lie. He meets a dog from the Crystal Dimension named Toronto who becomes his attorney and secretary, and together they gain a cult following by conning people into believing they are true royalty. He is a constant annoyance to Princess Bubblegum, who frequently denounces him as the fraud that he is. Despite this, many residents of Ooo still follow him without question. [Steve Wolfhard's Twitter, S06E42 Hot Diggity Doom, S08E04 Lady Rainicorn of the Crystal Dimension, S05E44 Apple Wedding]
Oh great. The "King of Ooo" is here. Don't make eye contact, BMO. Next thing you know, he'll be sleeping on your couch for twelve years.
Princess Bubblegum [Adventure Time #43]
A pygmy elephant named Tree Trunks lives in the Tiny Mammal Kingdom. When she is a child, she dreams of joining the Candy Kingdom's Banana Guard. [S10E06 Ring of Fire, Banana Guard Academy #1]
She graduates high school and immediately gets married to a rhino named Randy at the age of eighteen. However, she abandons him just before their honeymoon:
It's over Randy. I'm a wild child.
Tree Trunks [S10E06 Ring of Fire]
She becomes the captain of a pirate ship called La Femme du la Mer and loses an eye. While on a voyage, she meets a boar named Daniel Prince and they briefly get married until she realises that his sob story was a ruse invented by her first mate Mr. Faidutti so that he could take the ship. Tree Trunks maroons Daniel on a desert island and blows up La Femme du la Mer. Upon returning to the mainland and giving up piracy, Tree Trunks invests her pirate treasure into establishing a large-scale shipping business which has strong ties with MO Co. She falls in love with her secretary, a seal named Wyatt. She sells the company, donates all her money to the King of Ooo, and retires to the Candy Kingdom with Wyatt where they maintain an apple orchard. They divorce a while later. [S10E06 Ring of Fire]
Lake Butterscotch? But I haven't been there in years. The last time was with Wyatt. I was so happy when I first met him. But soon I couldn't wait to get away...
Tree Trunks [Banana Guard Academy #2]
Yeah, she left me. She said I was stifling her spirit.
Wyatt [S05E44 Apple Wedding]
Tree Trunks' fourth marriage is a polyamorous relationship with a group of grey aliens, with whom she has five hybrid children. [S08E17 High Strangeness]
Note: The spelling of Mr. Faidutti's name has not been confirmed. The spelling used here is an actual French surname and was taken from the television subtitles.
Marceline begins dating a jerky wizard named Ash, possibly to prove a point to Bubblegum. They convert the willow tree that grew over Shoko's corpse into a house called the Tree Fort, and move in together. Marceline carves an "M" into the bark to indicate her ownership. [S03E03 Memory of a Memory, S01E12 Evicted!, Beginning of the End #1]
While Simon has been almost completely pushed out of his mind by the Ice King, he still seems to retain some sense of attachment to Marceline. As a result, he is constantly following her around and tracking her to wherever she lives.
Every time I move eventually you find me and start hanging around.
Just another lame excuse to see me. Man, it's getting me down.
Marceline singing Nuts [S04E25 I Remember You]
Due to this, Ash and Marceline eventually move out of the Tree Fort to a shack in the woods. Marceline leaves the Red Amulet at the Tree Fort. Their relationship quickly becomes more fragile. One day, Ash sells Hambo, the plush that Simon gave Marceline when he found her immediately after the war. It is bought by Maja the Sky Witch at a high price thanks to its high sentimental value, which is useful in spell crafting. [S05E29 Sky Witch, Adventure Time #25]
Finally tired of Ash's jerkiness, Marceline violently breaks up with him:
It's over, you psycho!
Marceline [S03E03 Memory of a Memory]
Two star-crossed lovers, Warrior Princess and Clarence, find themselves on opposite sides of a battle for an abandoned wind farm.
Before her demise, Ghost Princess fell in love with her enemy's leader, Clarence. To avoid fighting each other, they had to make phony excuses to their soldiers. Finally there was too much pressure and Ghost Princess and Clarence announced tomorrow they would go to war. But unbeknownst to Ghost Princess, Clarence had cast a Spell of Invincibility on her armour so he wouldn't accidentally kill her in battle. Unfortunately, the day before the battle, the Princess ate a hot dog and spilled mustard all over her armour. Not wanting to look like a slob on the battlefield, she changed into her backup armour, which hadn't been charmed, and Clarence accidentally killed her.
Chapter Eight of the Heroes' Enchiridion [The Enchiridion & Marcy's Super Secret Scrapbook]
Warrior Princess loses her mortal memories and becomes known as Ghost Princess, doomed to haunt the mortal plane until she can figure out how she died. A Squeez-E-Mart convenience store is eventually built on the site of the battle. It is the place where Clarence would much later take his own life. [S03E24 Ghost Princess]
Note: This must have happened some time ago because Boilbee claims that Ghost Princess has been in the graveyard longer than almost anyone else.
A fantasy card game called Card Wars becomes popular, and an annual doubles tournament is held on an abandoned oil rig. It is mostly attended by turtle people, but many different species take part.
Welcome, Charlie, to the fifty-ninth Card Wars Doubles Classic.
Jake in 1000 AMB [S08E11 Daddy-Daughter Card Wars]
Alva and a group of Swedish humans embark on an expedition from Founders' Island to another island in the chain called Back-to-Nature Island. They establish experimental artificial weather systems and a small colony. However, something goes wrong. Almost every human on the island is killed by either the malfunctioning weather system or the giant wildlife, leaving Alva as the lone survivor. [S08E22 Mysterious Island]
Freakin' Back-to-Nature Island!
Martin Mertens complaining about a spontaneous storm [S08E25 Min and Marty]
Alva manages to befriend some of the wildlife, including a giant bear named Albert, and lives in a teched-out tree base for the next fifty years or so. [S08E22 Mysterious Island]
Grandpa? I'm only thirty-seven!
ASMoLG in 1000 AMB [Ice King #4]
The Ancient Sleeping Magi of Life Giving is a being capable of bringing to life anything that he touches. He is raised as a wizard by his oppressive father and his loving mother. [S05E10 Little Dude]
At some point, he becomes contained within the Mystery Dungeon, probably to prevent him from accidentally bringing things to life as he so constantly does after his release. [S05E08 Mystery Dungeon, S05E10 Little Dude]
The Islands are locked off to the rest of the world. Nobody is allowed to enter or leave, and many of the hiders who try to escape are killed by the Guardian. Others are captured by the "seekers", genetically engineered super-humans who prevent people from leaving the Islands' shores and send captured hiders to re-education. The seekers have implants in the side of their heads which can be used to feed information directly into their brains. These implants are engineered by their mentor Doctor Gross, and they also serve the secret function of giving her complete authority over her seekers' actions without their permission. [S08E24 Hide and Seek]
All children born on the Islands are given a function from early childhood, and Kara Strong (designation "Seeker X-J-7-7") is destined to be a seeker. Kara's best friend is an experimenter (engineer) named Frieda. Kara and the other children on the island are raised believing that the Islands are a utopia and that the rest of the world is completely filled with deadly monsters and diseases:
The hiders fear these new ideas
But do your best to help them
'Cause just outside is darkness and death
Disease, monsters and problems
The Founders' Song [S08E24 Hide and Seek]
And we went to LSP's quinceañera.
Finn in 996 AMB [S02E02 The Eyes]
LSP is born to her parents, Lumpy Space King and Queen. LSP is the reincarnation of the so-called "Lumps Anti-Elemental", a being capable of negating the magic of the other four elements: Fire, Ice, Candy, and Slime. [S09E09 Skyhooks II]
She is raised in Lumpy Space, a land rife with teen drama. She attends school for a while where she has a lab partner who she calls "Ugly Johnny" and a boyfriend named Michael. She grows up to be a selfish brat along with most of her fake friends (including her "BFF" Melissa) and her multiple temperamental boyfriends, with Brad being her most recent ex before the start of the show. [S09E09 Skyhooks II, S05E49 Bad Timing, S01E02 Trouble in Lumpy Space]
Phoebe is born to the Flame King, ruler of the Fire Kingdom. She is the reincarnation of the Fire Elemental following the death of the previous one in the Great Mushroom War. While she is still a baby, the Flame King hears a prophecy that her powers will be far greater than his own, and so has her cast out into the wilderness to perish for fear of being usurped. However, his squire takes pity on the child and leaves her in the care of a lumberjack near the Candy Kingdom. Phoebe, who doesn't know any better, burns down his house and begins carving a path through the forest. After a destructive rampage through Ooo, she reaches the Candy Kingdom and is returned to the Fire Kingdom by Princess Bubblegum:
You can't just let her run around the woods. She's too dangerous. Find some way to contain her power, or I will.
Princess Bubblegum [S05E31 Earth & Water]
Begrudgingly, the Flame King has his daughter imprisoned in a lantern for the next fourteen years of her life. Princess Bubblegum believes that if she is ever allowed romantic interaction, she could burn the world. [S03E26 Incendium, S04E16 Burning Low, Mysteries of Ooo - Flame Princess]
Note: In Son of Rap Bear, SORB claims that Phoebe has been in a lantern since the age of two. However, this would either make her two years older than Finn or make Jake two years younger than Finn (see continuity note in next section), neither of which seem to be the case. He probably just chose this number because it rhymed.
Two married talking dogs named Joshua and Margaret run a private investigation bureau in the ruins of an old human city. Margaret is pregnant with their child, so they take on what seems like a danger-free case:
Wait, wait, here's one. "Woman's pies go missing in bucolic countryside where nothing ever happens." The perfect case for my pregnant wife!
Joshua [S06E16 Joshua & Margaret Investigations]
They discover that the "monster" burgling Tree Trunks' pies is actually just her husband Wyatt, which is probably one of the causes of their later divorce. While Joshua and Margaret are leaving, they discover the trail of a real monster, and begin tracking it despite Joshua's objections. It turns out to be Warren Ampersand, the shape-shifter from Nerraw, who bites Joshua's head before retreating back to his own world. Warren had impregnated Joshua, who gives birth to Jake from his head. Jake is a half-dog half-shape-shifter hybrid, and possibly the reincarnation of the Yellow Catalyst Comet as well as the newest child of Warren Ampersand. Moments later, Margaret gives birth to Jermaine in a more traditional fashion. [S06E16 Joshua & Margaret Investigations, S10E10 Jake the Starchild]
Yes, we've got one boy that I gave birth to, and one boy you gave birth to. Let's never tell them how it happened.
Joshua and Margaret [S06E16 Joshua & Margaret Investigations]
Note: Marceline is awake at this point, since Joshua mentions a "vampire girl spotted in the Grass Lands harassing sheep and cattle". He also says "small fire goblin burns down Candy Kingdom forest", which means Flame Princess is slightly older than Jake and Jermaine.
I've read all the old stories about them, y'know. About other places and people. I'd like to see those places one day. Meet those people. It can't all be monsters.
Frieda [S08E24 Hide and Seek]
The experimenter Frieda becomes a hider and plans to escape the island by constructing a transport out of stolen parts. She is discovered by her best friend Kara, who decides to help her escape despite being a seeker. However, Doctor Gross follows Kara to the coastline and uses her implant to force her to capture Frieda. Frieda is sent to re-education and never makes another attempt to leave, eventually becoming a toymaker at a shop called Leksa Ker. [S08E24 Hide and Seek, S08E26 Helpers]
I grew up, and I learned to accept the Founders' truth.
Frieda [S08E27 The Light Cloud]
Martin Mertens is a human conman living on Hub Island. He tricks hiders into gathering on the beach for fake escape plans and then reports them to the seekers for capture, reaping reward from both sides. One day, a hider named Widow sees through his con and makes him accompany her to the beach. Widow and the other hiders are captured and sent to re-education. The seekers also mistake Martin for a hider, and Kara Strong breaks his legs, hospitalising him. A "helper" named Doctor Minerva Campbell is charged with treating Martin's injuries.
You're alright, doc. Hey, y'know I'm not going to re-ed tomorrow, right? I'll tell them this was just a misunderstanding and then I'll glide out the front door a free man. Free to have dinner... with you?
Martin Mertens [S08E25 Min and Marty]
The unlikely couple end up falling in love. Minerva helps Martin to avoid re-education and they move into a house together. Martin becomes a barber while Minerva continues to become one of the most respected helpers on the Islands. They have a child named Finn Mertens, designation "Infant P-G-8-7". [S08E25 Min and Marty, S08E20 The Invitation]
Finn is the reincarnation of the Blue Catalyst Comet's Agent of Change. [S06E43 The Comet]
After escaping re-education, Widow and a group of hiders break into Martin's home in an attempt to enact revenge. Martin and baby Finn hide out on a raft to escape them, but the Guardian mistakenly believes that they are trying to escape the island. In the resulting battle, Martin manages to blind the Guardian before being thrown out into the ocean. He and Finn become separated and both inadvertently leave the island.
I can't believe that of all the hundreds that have tried, the gallbag that finally makes it past the Guardian is Martin Mertens!
Widow [S08E25 Min and Marty]
Finn remains on the raft, surviving on breadsticks, and eventually washes up on the shores of Ooo, leaving him with an extreme fear of the ocean. Joshua and Margaret discover him stuck to a leaf by his own poop in the woods, and decide to adopt him alongside their own pups. He becomes the adoptive brother of Jake and Jermaine. They name him Finn after mistaking him for a mudfish, which is coincidentally his real name. Alternatively, his name might have been written on his hat, since it is seen written on his toy bear. [S01E16 Ocean of Fear, S01E10 Memories of Boom Boom Mountain, The Adventure Time Encyclopaedia, S08E25 Min and Marty]
For a long time, the inhabitants of mainland Ooo believe Finn to be the last full-blood human in existence, since nobody is aware of the Islands. [S02E18 Susan Strong]
Meanwhile, back on Hub Island, Minerva is distraught over the loss of Martin and Finn. Doctor Gross dispatches Kara Strong, her most powerful seeker, in an attempt to retrieve them, but she wouldn't return for fifteen years. [S08E25 Min and Marty]
Martin is pulled from the ocean by the same crew that was once captained by Tree Trunks. He has a severe head injury, which is probably the cause of his memory loss and insanity later in life. [Min and Marty promo art]
Note: The promo art for Min and Marty suggests that it was Tree Trunks' crew (from Ring of Fire) who pulled Martin from the ocean. However, Tree Trunks was already living in the Candy Kingdom with Wyatt at the time of Jake's birth as shown in Joshua & Margaret Investigations. For Tree Trunks to have been captain of La Femme du la Mer at the time of Martin's escape, either she would have had to build and sell off her company in a matter of months, or Finn is significantly older than Jake, neither of which seem plausible. Therefore, Mr. Faidutti must have survived Tree Trunks' attempt to murder him, and Tree Trunks probably never knew Martin.
Following this, Martin somehow ends up in space, where he becomes a criminal and, for the most part, forgets about the family he used to love. However, he still maintains some memory of his past:
So one day, I got called on a dangerous mission. Like, a dangerous life choice. Two roads diverging in the night and all that. And I couldn't bring you along. I always planned to come back for you, but I didn't. That's... true.
Martin Mertens [S06E27 The Visitor]
At some point, he commits a Cosmic Crime by pulling a con so great that he gets into trouble with the Cosmic Entities. He is imprisoned in the Citadel, a prison dimension, and frozen in crystal along with many of the worst abominations and criminals in the Multiverse. [S06E02 Escape from the Citadel]
The Citadel is a nasty-sized prison. Only the worst of the worst end up there. Real stink faces.
Prismo [S06E01 Wake Up]
Note: Unused storyboards from The Lich suggest that Martin used to be a great warrior and was put in the Citadel by mistake. Given what we now know about his history and personality, this is probably false.
Something goes wrong with Kara's mission to Ooo, and her transport crashes. She is left with severe amnesia and forgets almost everything, including her own name. [S08E20 The Invitation]
She joins a tribe of "hyoomans": humanoid fish creatures who live underground in an abandoned shopping mall called Beautopia, which could be the same mall where the human refugee camp existed following the war and where Marceline camped out before becoming a vampire hunter. The hyoomans are evicted from their home by gaseous monsters known as lub glubs, and retreat to a bunker beneath the Candy Kingdom. They are fearful of the outside world, so remain hidden for years. [S02E18 Susan Strong, S03E14 Beautopia]
Joshua captures and chains up his long-time demonic nemesis Kee-Oth. He drinks holy water to make himself immune to Kee-Oth's blood-sucking ability, so Kee-Oth sucks his own blood and uses it to forge a sword with which to escape. However, Joshua stops him and steals the sword. He stores it in a dungeon for Finn to find years later. [S05E41 The Pit]
Finn! If you're seeing this pre-recorded holo-message, it's because you finished the dungeon I made for you. I'm proud of you. You're gonna do great things in this world. I love you, son.
Joshua [S03E25 Dad's Dungeon]
Kee-Oth retreats to the Broke-up Dimension and seeks vengeance upon Joshua. [S05E41 The Pit]
Since BMO had an uptime of 4748 days (exactly thirteen years) in 998 AMB, he must have undergone a reboot in about 985 AMB. [Adventure Time #13]
This reboot might be the reason that BMO does not remember the details of his own creation, since the mind of a MO is wiped during the re-installation of system drivers. However, this could just be a result of his highly inaccurate memory recollection. Despite this, BMO retains emergency instructions detailing how to get back to the MO Factory should he ever need new core system drivers. [S05E28 Be More, S09E11 Ketchup]
It is unknown when exactly BMO enters the lives of Finn and Jake. He could have belonged to Marceline in the Tree Fort before they moved in, or Finn and Jake could have adopted him on a whim like they tried to do with the jiggler, or he could have belonged to Joshua and Margaret. The only certain thing is that he lives in the Tree Fort by the beginning of the show.
He gets his supply of fresh batteries from an old pre-war electronics shop near the Tree Fort. [Adventure Time #56]
A great magician queen is banished to a different dimension for using magic to spy on her people. However, she creates a daughter named Gata, whose mouth contains a portal to the other dimension, and leaves her in Ooo so that she may one day return. [Adventure Time #49]
Gata wanders the land and ends up climbing in through Joshua and Margaret's window. They decide to raise her as a sister to Jake and Jermaine. Later on, after Finn has also joined the family, Joshua closes the portal in his adopted daughter's mouth by using a magical item which turns her into a stone statue and erases her from the memories of everyone who knew about her. Her entire family forgets that she ever existed. [Adventure Time #48]
Baby, we moved out to the country with two nice boys, a boom boom human, and a sweet girl who's a wide open portal to a horror realm.
Joshua [Adventure Time #48]
In the future, a creature called Clock Bear escapes from Doctor Gross' menagerie and hides out in the attic of Joshua and Margaret's private investigation bureau. He causes several "time slips" between the 980s and 1001 AMB, making the house seem haunted. This also allows the future versions of Finn and Jake to subtly interact with their dead parents, and future Jake witnesses his own unconventional birth. [S10E08 The First Investigation]
Oh boy, our first case. Looks like we have a poltergeist. And it's got a little crush on me. What a sassafras.
Joshua [S10E08 The First Investigation]
At some point, the family moves out of the investigation bureau in the city and into a large house atop a hill in the countryside. [Adventure Time #48, S10E08 The First Investigation]
While the boys seem to have a fairly close relationship with their parents, things are not as simple as they might seem. Margaret is overprotective of her children and limits their freedoms. On the other hand, Joshua is eager for his children to become adventurers like him and designs deadly dungeons for them to take part in. He even teaches Jake how to pickpocket. This combination probably makes for an unhealthy family dynamic and could be responsible for Jake's later criminality. [S05E06 Jake the Dad, S03E25 Dad's Dungeon, S10E10 Jake the Starchild, S05E23 One Last Job]
Everyone leaves. Except me. I remember father made me stay at the table until all the eggs were eaten.
Jake [S09E04 Winter Light]
In addition, Jermaine appears to take a back seat behind his two brothers. He isn't a powerful shape-shifter or an exotic human, so his parents seem to show less interest in him than in their other two boys. He is once accidentally knocked out by Jake while they are play-fighting. Jermaine probably craves attention from his parents, which might explain why he's the one who would later stay and look after the house following their death. [S02E08 Crystals Have Power, S06E33 Jermaine]
Both parents also keep secrets from their children. They never tell Jake the true origin of his powers or that Margaret is not his biological mother. Jake grows up believing that he gained his powers from rolling in a magic mud puddle and Finn grows up believing he was born from a cabbage. [S06E16 Joshua & Margaret Investigations, S01E14 The Witch's Garden, S01E22 Henchman]
However, it wasn't all bad. All three children clearly loved their parents.
Ah man, my dad use to make pickles. It's all he use to talk about. He'd obsess about them all the time. When I'd come in from playing he'd be like, "Here, Jake, try these!" And they'd be pretty crunchy. Actually you'd think they'd be soft but they weren't. I'd be like, "Wow Dad! You'd made these pretty good!" Yeah, that was Dad.
Jake [S05E02 Jake the Dog]
Joshua warns Jermaine that Jake might go through some changes someday due to his true nature as a shape-shifter, and tells him to be supportive if and when it happens. [S09E10 Abstract]
Many of the citizens of Princess Bubblegum's Candy Kingdom eventually develop their own distinct backgrounds and personalities. These are just a few examples.
Peppermint Butler, one of Bubblegum's earliest creations, is created to be her servant. He fulfils this task and becomes the princess' loyal butler and also one of her closest advisers. But on top of that, he develops a strange interest in the dark side of magic. He secretly becomes a dark magician and acquaints himself with several powerful entities including Hunson Abadeer and Death himself. [S05E34 The Vault, S06E15 Nemesis, S02E17 Death in Bloom, The Adventure Time Encyclopaedia]
I am a powerful magi of old ways. I have seen the twisting infinite planes of life and un-life. I have scratched through the film of reality, and know the truths of magic and mundanity. But I cannot comprehend a time before my own existence. I was brought into being by Princess Bubblegum. I know none more powerful. I love and fear her in equal measure. I am proud to be her butler, because I know no greater honour than to serve this goddess with the full might of my abilities.
Peppermint Butler [Adventure Time #44]
Peppermint Butler also establishes S.W.E.E.T.S., the Candy Kingdom's secret service. [Adventure Time #41]
Bubblegum creates a sugar ostrich which lays a delicate sentient egg once every ten years, leading to the rise of a society called the Fancy Egg Folk who live atop a mountain, safe from the perils of the outside world. [Adventure Time #40]
In 968 AMB, the first baseball event known as the "Annual Royal Banana Guard Post Season Apology Game" is held. [S10E01 The Wild Hunt]
Captain Banana Guard is also granted his captaincy at some point.
I remember my first day at the academy. It was raining, and I was late leaving my house, so I ran as fast as I could down Cobbler Lane. I tripped over a root and fell down, instinctively protecting my school books instead of my face. Oh sure, I may have bloodied my nose and shattered three teeth that morning. But you know what? I made it to the academy on time. I was two years old. Since then I've dedicated my life to the guard. Quickly rising through the ranks like a fearless mountain goat. I was the youngest banana to ever make captain.
Commandant Banana Guard [Banana Guard Academy #2]
As a child, Cookie (AKA Baby Snaps) is raised in an orphanage. One day, Princess Bubblegum visits. She unknowingly insults him, and he holds a grudge that eventually develops into a mental illness.
Everything was better with her around. And something inside me changed that day, too. And then later she told me I could be anything I wanted. And I told her I wanted to be a princess like her, so I could make all the children happy. And she laughed in my face, man! It really messed me up. She lied to me!
Cookie [S04E13 Princess Cookie]
When she is a teenager, Betsy Pound Cake runs away from her life after not having the courage to break up with her boyfriend Justin. She studies medicine and eventually becomes a nurse working in the Candy Kingdom Hospital.
Okay, so riding out your teen years in a cave is pretty dramatic, but do you know how much reading you get done in a cave?
Betsy Pound Cake [S06E30 The Diary]
Braco is born in 977 AMB. He is the son of Loghan and the grandson of Hobus, a family who have been fruitlessly waiting for the opportunity to court Princess Bubblegum following her breakup with Marceline and the death of Mr. Cream Puff, her previous love interests. Many other candy people also wait in line to court the princess, some of whom have been waiting for up to three hundred years. [S05E21 The Suitor, S01E01 Slumber Party Panic]
I'm Braco, and I was born to court the Princess Bubblegum.
How old are you?
Twenty-one years. I inherited my father's place in line after his ascension.
Braco (and Peppermint Butler) in 998 AMB [S05E21 The Suitor]
Two candy people named Root Beer Guy and Cherry Cream Soda are created by Princess Bubblegum and married to each other. Cherry Cream Soda is a lawyer. Root Beer Guy works in a call centre, but he spends much of his free time reading detective novels. In 989 AMB, he eventually begins writing one of his own, and spends ten years working on it. His obsession with his writing causes tension in the marriage. [S07E03 Cherry Cream Soda, S05E43 Root Beer Guy]
I swear sometimes I think you love that novel of yours more than you love me. You've been working on it every night for ten years and for what?
Cherry Cream Soda in 999 AMB [S05E43 Root Beer Guy]
Also in 989 AMB, a candy person named Todd Cupcake falls in love with a banana guard lady. However, the lady tells him that she cannot have relationships outside the force, so Mr. Cupcake attempts to join the Banana Guard but his application is rejected. He gives up after a fruitless and expensive legal battle during which he loses his job, but promises to join the Banana Guard should the opportunity ever arise. [Banana Guard Academy #1]
Beginning in 995 AMB, a candy person named Starchy begins hosting a call-in radio show called the Graveyard Shift about supernatural stories and conspiracies from around the Land of Ooo. It's possible that the collective imagination-magic of his listeners causes some of the supernatural made-up entities he talks about to actually manifest, such as the blank-eyed girls, an urban myth who begin being sighted around the Land of Ooo at the same time as the show begins. [S05E39 We Fixed a Truck, S07E19 Blank-Eyed Girl]
You know what today is, everybody. It's our fifth anniversary show.
Starchy in 1000 AMB, on the Graveyard Shift [S07E19 Blank-Eyed Girl]
Before the war, most of the creatures on Earth were unintelligent, lacking the ability to speak. Humans were the only exception. However, following the war, a wide variety of talking animals appeared in the Land of Ooo. They are either inhabitants of other dimensions, or mutated versions of Earth's native species. Two such talking animals are Choose Goose and Games Bookstore (pronounced James Baxter).
A gosling named Chauncey is born the heir of a wealthy earldom. He leaves his home to explore the world but with the ultimate goal of finding new ways to make his family even richer. One day, he stumbles across a grove of highly valuable bloodberries and begins to pick them, not caring that they belong to a witch. Chauncey mocks the witch for her habit of speaking in rhymes, for which she curses him with the same affliction and alters his body to look sillier. Following this, Chauncey finds that nobody takes him seriously anymore, and he is outed from his family. He renames himself to Choose Goose and takes the life of a travelling merchant.
Choose Goose realised he'd only ever been good at one thing. Buying and selling. As a cursed bird, this proud capitalist had found his final cage.
The Crone [Adventure Time Comics #16: "The Bummer Story of Choose Goose"]
A horse who works in a bustling city chooses to quit his high paying job to explore the world and find his calling. After meeting an upset bat, the horse discovers that his true skill is cheering people up. He renames himself after two shop signs he sees: "Games Bookstore". But he mispronounces the words and becomes known as "James Baxter". Riding atop a beach ball, he tours the Land of Ooo neighing out his own name and bringing joy to everyone he meets. [S08E18 Horse and Ball]
In 599 AMB, Princess Bubblegum establishes diplomatic ties with three kingdoms by helping them in various ways: She defeats some evil slug lords for the Sea Caves, prevents a molasses flood for the Mountain Pass, and saves the Spirit Hollow from the "Plague of Royma". In return for Bubblegum's help, the kingdoms give her magical crystals which she uses as part of the Candy Kingdom's power network. Every ten years, she returns to the kingdoms so that they can recharge the crystals for her.
Guys! Friends! That was four hundred years ago. We were happy to help.
Princess Bubblegum in 999 AMB [Bitter Sweets]
Note: In Bonnie and Neddy it was revealed that the Candy Kingdom is powered by the juice produced by Neddy.
Following Bubblegum's most recent visit to the three kingdoms to recharge her magic crystals, the Sea Caves and the Mountain Pass steal several stones from the walls of the Spirit Hollow, and begin taking magical lights from around the kingdom. The Sea Caves and the Mountain Pass use the stolen energy from these items to improve the state of their own kingdoms. They are unaware that the lights are actually living spirits. The Spirit Hollow falls into darkness. [Bitter Sweets]
You and your father were never coming back. Dark days grew darker. I went into myself. And while I retreated, Doctor Gross' work turned strange and dangerous. Her actions unwittingly led to the release of a terrible virus. We tried to consolidate and quarantine everyone on Founders' Island. The fatality rate in the general population grew to sixty-two percent. But the fatality rate in helpers - those who faced the virus daily - was one hundred percent. Or nearly.
I was only one helper, and in no condition to do my job. I made my decision. With my brain-map loaded to the web, I could be hundreds of helpers. And humanity needed help above all else. Since that day I have protected and cared for all my people.
Minerva Campbell [S08E26 Helpers]
Minerva uploads her consciousness into an army of robots, which are eventually able to vanquish the virus. Hub Island becomes completely abandoned, and most of the islanders move to Founders' Island, with the exception of Alva (who is still stuck on Back-to-Nature Island) and the Better Reality players. [S08E26 Helpers, S08E22 Mysterious Island, S08E23 Imaginary Resources]
Doctor Gross, who knows she is guilty of causing the deadly epidemic, flees the Islands in her mobile laboratory and travels to Ooo, where she continues experimenting on animals. [S08E12 Preboot]
One winter, Finn and Jake are out on a walk in the snow with their father Joshua. They discover the Tree Fort, which has been recently abandoned by Marceline, and decide that they will move in together someday.
Oh boy, Jake. We should live here! We'll have a lookout post, and a sword room, and our own bathroom, and have adventures, and fight monsters, and be heroes! Jake, I promise, when we grow up, we'll live here, and be best friends, and spend every day together, having adventures for all time!
Finn [Beginning of the End #1]
By making this statement, Finn accidentally makes an unbreakable oath in the name of Chronologius Rex, the "lord of all-time", meaning that he will be punished if he ever breaks his promise to Jake. [Beginning of the End #1]
They probably begin using the Tree Fort as a base at around this time, since Joshua's directions to his dungeon start at the Tree Fort. It is not known when they start living their permanently, although it is probably sometime shortly after their parents' deaths. They are unaware that it still legally belongs to Marceline. [S03E25 Dad's Dungeon, S01E12 Evicted!]
In the closing years of the wars in the Crystal Dimension, an enemy dog saves the life of a high-ranking flying saucer pilot named Bob Rainicorn. Bob and his wife Ethel become indebted to the dogs, and the war ends not long after. They move into a house without realising it is built above an abandoned collapsing crystal mine left over from the wars. [S02E12 Her Parents, Marcy & Simon #5]
Bob and Ethel have a daughter named Lady Rainicorn, who begins dating Lee, a cynophobic activist who spends his time committing hate crimes against dogs. Despite the end of the war, tensions between the two species are still high.
Whatever does she see in such an idiot?
Ethel Rainicorn [S08E04 Lady Rainicorn of the Crystal Dimension]
Lee and his gang eventually hatch a plan to steal a weapon called the Crystal Mergence of Destruction from a dog military base. Believing that this could trigger another war, Lady stops his plan and is forced to flee to the Earth Dimension with the weapon, where she goes into hiding. She begins living in a barn near the Candy Kingdom and becomes friends with Princess Bubblegum. [Mysteries of Ooo - Lady Rainicorn]
Mum, Dad, I've got to get out of town fast. Listen, I don't know if I can ever come back. The Crystal Mergence must be kept far from here.
Lady Rainicorn [S08E04 Lady Rainicorn of the Crystal Dimension]
Due to the fact that dogs age much faster than humans, Jermaine and Jake mature a long time before Finn does. After graduating from college while Finn is still a young child, Jake leaves home and undertakes a variety of activities. Most notably, he becomes the leader of a group of criminals consisting of himself, Gareth, the Flying Lettuce Brothers, and Tiffany. His criminal record causes him to lose his right to vote. [S10E10 Jake the Starchild, S05E23 One Last Job, President Bubblegum]
He also becomes a high ranking Card Wars player and dates an equid named Moniker DeLuise for a short time, who teaches him to read Braille. He loses the Card Wars champion title to Grand Prix and quits the game, breaking up with Moniker in the process. As if rubbing salt in the wound, Moniker would go on to date Grand Prix. Jake develops a deep resentment for anyone who beats him at the game in the future. [S08E11 Daddy-Daughter Card Wars, S05E13 The Great Bird Man, S04E14 Card Wars]
Man, I thought you swore off tourney play, like, angrily swore it off.
Grand Prix [S08E11 Daddy-Daughter Card Wars]
Following this, Jake writes a misleading dating advice book called Mind Games under the secret pen name J. T. Doggzone and begins writing a newspaper advice column called Begs the Question, both of which gain considerable popularity. He starts dating the fugitive Lady Rainicorn, learns to play the viola, and learns to speak Korean. [Mysteries of Ooo – Jake the Dog, S01E19 The Duke, The Adventure Time Encyclopaedia, S01E09 My Two Favorite People]
Jermaine, meanwhile, pursues a career as a landscape artist. [S09E10 Abstract]
Both Joshua and Margaret die of unknown causes. Finn and Jake bury them and begin living in the Tree Fort permanently, leaving their brother Jermaine to begrudgingly look after their dead parents' old house and keep at bay all the demons seeking to retrieve the possessions stolen from them by Joshua.
I didn't win! When do I win? Special guys one and two win every day! Cracking jokes, reading foodie mags in your tree-town fun-house. Must be nice to be so special you can go off and find your own fancy ways. Meanwhile I gotta stay here and watch dad's trashy booty because I never stretched into the sky and farted on the wings of a falcon I guess!
Jermaine [S06E33 Jermaine]
Shelby, a worm priest who ends up living in Jake's viola, probably also moves into the Tree Fort at around this time. [S02E23 Video Makers, S05E41 The Pit]
Since there is so much Adventure Time content, only plot-relevant episodes and comics will be covered here. You can view a complete listing of all Adventure Time media, as well as the approximate year in which they take place, here.
Jake gives up his life of crime so that he and Finn can pursue a career of adventuring and heroism. They first meet Princess Bubblegum after rescuing her from kidnap by the Ice King, and Finn quickly develops an unrequited crush on her. Finn and Jake become protectors of the Candy Kingdom and continue to have frequent clashes with the Ice King, who becomes their main enemy due to his unhealthy habit for kidnapping princesses. The season one status quo is established. [Adventure Time pilot]
At some point, Finn obtains a golden sword which he names "Scarlet", and he swallows a tiny computer that enables him to talk and sing in autotune. Finn's fear of the ocean causes him to manifest a parasitic entity called the Fear Feaster who lives inside his belly button. [Hey Ice King! Why'd You Steal Our Garbage?!!, S01E06 The Jiggler, S01E16 Ocean of Fear]
Recognising Finn's heroic potential after he saves her from falling from a tower, Princess Bubblegum sets him a quest to retrieve the Enchiridion from its hiding place on Mount Cragdor. After passing all the trials Finn and Jake take the book home, but they hardly ever read it. The only time Finn is ever seen reading it is to find a cure for his and Jake's injuries so that he can get rid of the clown nurses who Jake has hired. Finn finds out about the cyclops and its healing tears by reading the Enchiridion, and subsequently goes on to decapitate it and obtain the tears. [S01E05 The Enchiridion!, S03E23 Another Way, S04E07 In Your Footsteps]
It's a book meant only for heroes whose hearts are righteous. The book lies at the top of Mount Cragdor guarded by a manly minotaur. It's waiting for a truly righteous hero to claim it!
Princess Bubblegum [S01E05 The Enchiridion!]
Some of Finn's other heroic deeds from this time include saving a Mountain Man from having to watch the rough-housing marauders, moving the Grand Hall of Wizardry out of the path of the asteroid, rescuing the Drop Ball ghost from the Temple of Zeldron, and saving Mushroom Village from the evil baby pigs. [S01E10 Memories of Boom Boom Mountain, S01E11 Wizard, S02E04 Blood Under the Skin, S02E13 The Pods]
While rescuing the Mini Queen from a swamp giant, Finn and Jake stumble across Billy's sword Nothung which turns out to be the hidden entrance to Billy's Crack, the home of the retired hero. Billy tries to convince Finn and Jake to become non-violent but after struggling with this for a while they ignore his advice, deciding that violence is sometimes the only solution. Billy comes around to their point of view, and the sense of helplessness left by his failure to defeat the Lich begins to heal.
It's as if your words are filling a void in my very being. Finn and Jake; truly, you are my heroes.
Billy [S01E25 His Hero]
Marceline returns to her old Tree Fort and is surprised to find Finn and Jake squatting in it. She promptly evicts them, and also kicks them out of a cave which she had already claimed for herself. After Finn attacks her, Marceline decides to let them keep the Tree Fort as a gift. Marceline builds a new house inside the cave and moves in with her undead dog Schwabl. [S01E12 Evicted!, S02E01 It Came from the Nightosphere]
I'm not mean. I'm a thousand years old, and I just lost track of my moral code.
Marceline singing the House-Hunting Song [S01E12 Evicted!]
Despite the initial bumpy start to their friendship, Finn soon learns that Marceline is actually a decent person and only pretends to be evil to scare people like Finn and Jake. She even saves Finn and Jake's lives when her old ghost gang-mates, Wendy, Booboo, and Georgie, want to kill them. [S01E22 Henchman, S02E26 Heat Signature]
By this time, Marceline is still upset with her father for betraying her trust, killing the werewolves, and eating her fries. One day she invites Finn to her new house to help her record the Fry Song.
Marceline, if you're thinking about your dad so much then why don't you go see him?
He's not worth the effort.
Finn and Marceline [S02E01 It Came from the Nightosphere]
Finn, in a misguided attempt to repair their broken relationship, decides to summon Hunson from the Nightosphere without realising that he is evil. Hunson is reunited with his daughter, possibly for the first time in a thousand years, but predictably he begins stealing the souls of every creature he can get his hands on. To Marceline's horror and embarrassment, Finn uses the Fry Song to distract him. A moment of reconciliation occurs between Marceline and Hunson, but Finn cuts it short by banishing Hunson back to the Nightosphere and freeing the stolen souls. Even so, this event allows Hunson to begin to understand his daughter. [S02E01 It Came from the Nightosphere]
Note: It is not clear whether or not this is the first time Marceline has seen her father since banishing him after the fry incident. The comic Marceline and the Scream Queens heavily implies that Marceline has spent a lot of time in the Nightosphere in the past. This is further evidenced in the episode Heat Signature by the fact that Marceline mentions she used to be in a gang in the "Underworld", which could be synonymous with the Nightosphere. She also says during Finn & Jake Investigations that she once attended music school in the Nightosphere, but this could have been after reuniting with her father.
While Jake enjoys his new life as an adventurer alongside Finn, he begins to find himself juggling the various aspects of his life. Balancing his relationship with Lady and his relationship with Finn proves to be challenging for him.
I'm fed up, Shelby. Whenever I hang out with Lady Rainicorn, I miss out on fun times with Finn. And then when I hang out with Finn, I'm missing out on Lady Rainicorn.
Jake [S01E09 My Two Favorite People]
Jake successfully manages to get Finn and Lady to hang out with him at the same time, but he begins to worry that the two have grown too close. He calls Tiffany, an old member of his gang of criminals, to try to make them both jealous. Jake eventually makes up with Finn and Lady, but not before Tiffany pledges to kill Finn and take back his place as Jake's best friend. Finn chases him off for now. [S01E09 My Two Favorite People]
In addition to this, Jake struggles to hide his former criminality from Finn. When they visit the City of Thieves, Jake has to pretend to "accidentally" steal a pair of boots to provide an excuse for the fact that he can't pass through the anti-thief barrier surrounding the king's tower, even though the actual reason is due to his criminal past. [S01E13 City of Thieves]
All of this is not helped by the fact that Jake has an extremely short attention span. He knows that he has a responsibility to look after Finn, but he often fails to fulfil that responsibility, such as when he allows Finn to be captured by the gnomes who live beneath the Tree Fort. His powers have made him lazy, and when they are temporarily taken away from him by a witch he is completely unmotivated and can't be bothered to do anything about it. Finn claims that Jake always messes up his plans, which is why he doesn't tell him his plan to escape the Fight King's arena. [S02E07 Power Animal, S01E14 The Witch's Garden, S03E02 Morituri Te Salutamus]
I never really take anything seriously. Except Kompy's Kastle.
Jake [S04E21 Who Would Win?]
Jake's relaxed attitude also causes him to be quite accepting of his own mortality at this time. For example, he was willing to risk his life to get to the wishes at the centre of the Labyrinth. He is shown to put other people's lives ahead of his own, such as his refusal to murder Wildberry Princess even though he knew that the assassin Me-Mow would poison him if he didn't. Thankfully, he was able to use his powers to fight off Me-Mow's poison. [S02E22 The Limit, S03E16 Jake vs. Me-Mow]
One day, Jake has a dream where he dies in space alongside a mysterious Banana Man. Since the Cosmic Owl is present, Jake realises that this dream must be his prophetic croak dream, and believes that his imminent death is inevitable. He spends the following day trying to fulfil the dream and accept his fate. He and Finn meet the mysterious Banana Man, who turns out to be one of their neighbours, and Jake tries to steal his rocket to fulfil the dream. Luckily it doesn't have enough power to get into space. Instead, Jake nearly drowns in a cavern beneath the launch site, but is saved by Finn. The prophecy remains to come true another day... [S03E18 The New Frontier]
Despite being a powerful state, the Candy Kingdom comes under considerable threat from a variety of problems, including two zombie outbreaks, a freezer burn flu epidemic, an attempted hyooman invasion, and a successful invasion by an evil stag. Fortunately, Finn and Jake are able to save the day in each case, but it is not known why the kingdom so frequently has to resort to their help. [S01E01 Slumber Party Panic, S03E13 From Bad to Worse, S01E24 What Have You Done?, S02E18 Susan Strong, S03E15 No One Can Hear You]
And despite all my preparation, despite my greatest efforts, despite a nation's armament and my kingdom's best defences, in the end I still had to rely on a kid and this dog he knows to fix all my problems. Hah!
Princess Bubblegum [Adventure Time #24]
Finn's unrequited crush on Princess Bubblegum continues to develop. One day, Finn and Jake meet a witch who traps Jake in her "bottomless bottom" under the condition that Finn must bring her a lock of princess hair. Finn sets up a date with Princess Bubblegum and manages to get a wad of her hair, but the witch rejects it since it is actually made of bubblegum. Luckily, the witch instead accepts Finn's own hair and releases Jake. Finn gets to keep the wad of Princess Bubblegum's hair, and it becomes his most treasured possession. [S02E10 To Cut a Woman's Hair, S03E10 What Was Missing]
One of Finn's main shortcomings when it comes to courting the princess is his inability to match her intellect. One of the few times she ever kisses him is after he uses the Glasses of Nerdicon to make himself super-intelligent and summon a black hole. Finn loses the glasses after they fall into the black hole, and also loses Scarlet, his sword, while closing it. Princess Bubblegum also kisses him after he wins the Wizard Battle to "save" her from being kissed by the Ice King or another wizard named Abracadaniel. [S01E07 Ricardio the Heart Guy, S02E15 The Real You, S03E08 Wizard Battle]
Meanwhile, Princess Bubblegum's relationship with Marceline remains sour. Bubblegum usually does her best to ignore Marceline, so Marceline often deliberately tries to get on her nerves. The fact that Marceline deliberately messes up Finn's attempts to ask Bubblegum to the movies suggests that she still feels some attachment to her. [S02E20 Go With Me]
Simon Petrikov, now completely fallen to the insanity of Evergreen's crown, has become known to everyone but Marceline as "the Ice King". Some echo of his old self still desperately hopes for Betty to return to him, and as a result he is always trying to fill the void of his love life by kidnapping princesses, with Princess Bubblegum being his most frequent victim.
You don't understand! I collect princesses because I want to marry one.
Well why'd you capture six of them if you just wanna marry one?
I'm collecting them all first, to be sure I make the right choice.
Ice King and Jake [S01E03 Prisoners of Love]
He frequently comes up with plans to capture and marry princesses. These plans include hypnotising Old Lady Princess, shaving his beard to pretend to be a different person, kidnapping Doctor Princess under the guise of Gunter's pregnancy, and cheating his way through Wizard Battle for the chance to kiss Princess Bubblegum. His plans are always thwarted by Finn and Jake. [S01E17 When Wedding Bells Thaw, S02E03 Loyalty to the King, S02E11 The Chamber of Frozen Blades, S03E08 Wizard Battle]
Despite all this, Ice King believes himself to be a good person. He is jealous of Finn and Jake's relationships, and desperately tries to make friends with them so he can learn how to be a better person. Unfortunately his methods for doing so are usually unintentionally creepy or malevolent, but ultimately he has no intention to harm anyone. [S01E24 What Have You Done?, S02E02 The Eyes, S03E04 Hitman, S03E07 Still, S04E11 Beyond This Earthly Realm]
Ice King also attempts to connect with Finn and Jake by writing his own gender-swapped fan-fictions about them, titled Fionna and Cake. The existence of tapes containing "episodes" of a television show with the same name suggests that this might have been an actual show before the Great Mushroom War which Ice King is inexplicably connected to. He claims that ideas for the stories are beamed into his brain while he sleeps at night, which might actually be true. One account suggests that the origin of these information beams is a satellite named FELIS. Plausibly, this could be the origin of the mysterious anachronistic tapes as well. Ice King eventually becomes so obsessed with his stories that he refuses to allow them to be criticised, and desperately wants them to come true. [S03E09 Fionna and Cake, S09E12 Fionna and Cake and Fionna, Beginning of the End #3, Ted Anderson's Tumblr, S05E08 Mystery Dungeon, S05E11 Bad Little Boy]
Ice King sends some of his Fionna and Cake stories to a magazine called Ble, but upon visiting their offices and getting past the Pudding Troll, he discovers that all of the employees mysteriously died over five hundred years ago, and his submissions have just been lying in a heap by the front door. [S10E09 Blenanas]
Note: It's possible that the employees were already dead by the time the Pudding Troll was employed to guard the building, so the magazine might actually have ceased production before or during the Mushroom War. This would explain why the skeletons appear to be human and why the offices are in pre-war ruins. This is further evidenced by the fact that Bletters to the Bleditor, a piece in the SDCC 2018 crew zine, makes reference to several real world pre-war locations, such as Las Vegas and London.
Finn and Jake eventually learn about Ice King's tragic past by watching the tapes Simon made about his spiralling descent into madness. They come to see Ice King in a new light, and he begins to become an ally and a friend to Finn and Jake. [S03E20 Holly Jolly Secrets Part II]
Gunter, the penguin form of Orgalorg, still lives with the Ice King along with various other normal penguins. He gives birth to some kind of magical kitten. Ice King is largely neglectful towards Gunter which leads to Gunter stealing his demonic wishing eye and almost managing to use it to overrun the Candy Kingdom, hinting at his darker side. [S02E11 The Chamber of Frozen Blades, S04E24 Reign of Gunters]
By 996 AMB, Lumpy Space Princess is fourteen years old and fresh out of a breakup with her ex-boyfriend Brad, who has gone on to date her "best friend" Melissa. Though she appears to revel in the teenage drama of her home life, she recognises that most of the relationships she holds in Lumpy Space are unsubstantial or fake, and as a result she begins making frequent interdimensional trips to the Land of Ooo where she meets and somewhat befriends Finn and Jake.
I know I mess things up sometimes, but I'm really trying, and you're supposed to be my friend. Not like the fake ones I have here!
Lumpy Space Princess talking to Finn [S01E02 Trouble in Lumpy Space]
After her quinceañera (fifteenth birthday), LSP has a particularly bad argument with her parents. For one reason or another she runs away from home to live in the Land of Ooo. It is not certain whether she does this because she is sick of living in Lumpy Space or because she just wants to create more drama. Either way, she ends up homeless and camping in the woods, eating beans and roadkill. [S02E02 The Eyes, S02E10 To Cut a Woman's Hair, S02E26 Heat Signature, The Adventure Time Encyclopaedia]
Over the next few years, LSP returns home and then runs away several more times. After one particular argument, she is briefly adopted by a pack of wolves and then pretends to be a monster so that she can steal crops from a village. Finn and Jake find her and manage to get her to reconcile with her parents, but she continues to live as a homeless person whenever she visits Ooo. She usually camps in the woods, but also spends a lot of time living in the "Coolest Hotel". [S03E06 The Monster, Adventure Time #2, S04E09 Princess Monster Wife, S04E12 Gotcha!, S05E25 Candy Streets, S05E40 Play Date]
LSP maintains several other relationships within the Land of Ooo; both good and bad. One of her best friends is Turtle Princess, the ruler of the library. One of her most notable nemeses is Breakfast Princess. [S04E12 Gotcha!, Adventure Time #3: "Bacon Fields", S06E14 Princess Day]
Unlike many other characters, Lumpy Space Princess never really gets any kind of redemption or change of character. After all, stubbornness is a key component of elemental lumpiness. However, LSP is shown to become a little more mature over the course of the time she spends in the Land of Ooo. It seems like Finn and Jake somewhat inspire her to be a better person. [S09E09 Skyhooks II, S04E12 Gotcha!]
In 999 AMB when LSP is about eighteen years old, a Lumpy Space person named Johnny, who was LSP's lab partner in high school, travels to the Land of Ooo to make a business deal with Princess Bubblegum over the trade of bottled gas. He happens to meet LSP in a bar and she ends up falling in love with him.
Yeah, you used to call me that quite a bit.
Yeah... but I can't call you that anymore!
Lumpy Space Princess and Johnny [S05E49 Bad Timing]
Meanwhile, Princess Bubblegum has developed a "time travel" bubble which is capable of saving and loading the exact state of anything which is placed inside it. After LSP believes she has messed things up with Johnny she wants a do-over, so she tries to use the time machine to reset him back to "when he still loved her". But since Johnny has never been saved in the bubble, attempting to load a previous state simply deletes him from existence. Bubblegum then uses the time machine to remove LSP's memories of the whole ordeal. Johnny is lost forever, and LSP doesn't remember a thing. Nonetheless, for the early part of the relationship she acts uncharacteristically mature and seems to genuinely enjoy being with Johnny. [S05E49 Bad Timing]
Neptr (short for Never Ending Pie Throwing Robot) is a machine created by Finn to prank Jake. Neptr is brought to life after being struck by lightning, so Finn takes him to the Ice King to try to get more power. Neptr is left with two father figures: Finn, his creator, and Ice King, who imbued him with his own energy. However, he is ultimately neglected by both of them. [S01E15 What is Life?, S04E01 Hot to the Touch, S05E08 Mystery Dungeon]
You found Neptr! I am the ultimate Hide and Seek champion! Fifteen months, four days, nine hours and you guys didn't find me!
Neptr [S04E01 Hot to the Touch]
Another of Ice King's creations is Ricardio, who is created when Ice King accidentally animates his own heart. Ricardio becomes independent from Ice King's body and tries to cut out Princess Bubblegum's heart, but he is defeated by Finn and Jake and returned to the Ice King for now. [S01E07 Ricardio the Heart Guy]
Another of Finn's creations is the Ancient Psychic Tandem War Elephant, a creature from an unknown past war who Finn wishes into existence when he reaches the centre of the Labyrinth and claims his wish from Aquandrius. APTWE is able to use his own wish to save Jake from death after he over-exerts himself to get through the Labyrinth. Like Neptr, Finn and Jake are neglectful of APTWE and appear to forget that he exists until they find him in their treasure room while clearing it out. Despite being wished into existence, APTWE appears to have some past connection to Darren the Ancient Sleeper, a villain who will appear later on. One account also states that he knew Billy in the past. [S02E22 The Limit, S06E08 Furniture & Meat, S06E10 Something Big, Adventure Time #20: "Grocery Time Part 1"]
Shelby, the worm who lives in Jake's viola, accidentally cuts off his own butt. It becomes an independent being named Kent, who takes on the role of an adventurous younger brother. [S06E11 Little Brother]
While clearing out some tree stumps for Princess Bubblegum, Finn and Jake discover a hatch leading down into the cavern containing the hyoomans, the humanoid fish-people who Kara Strong lives with. They find Kara, who Finn believes to be a human, and rename her "Susan" after she fails to pronounce the word "Sun". After conquering their fear of the outside world, the hyoomans stage an attack on the Candy Kingdom, but are repelled using fire. Some of them remove their hats, showing their gills and revealing to Finn that they are not actual humans. However, Susan keeps her hat on and Finn doesn't find out whether or not she is also a fish-person. [S02E18 Susan Strong]
Jake, do you think she was human? Or just another wild animal?
We're all wild animals, brother.
Finn and Jake [S02E18 Susan Strong]
Later on, Susan approaches Finn and Jake again and asks them to help her retake Beautopia from the lub glubs. They successfully deliver fire back into the heart of the settlement, banishing the creatures who evicted Susan and her tribe, and Susan reveals to Finn that she has no gills, just like him. Finn is no longer the last known full-blood human in Ooo. [S03E14 Beautopia]
Because you're a human, just like me, Susan,
And I want you in my life.
Finn singing Susan Strong to Susan Strong [S02E18 Susan Strong]
From that point on, the hyoomans continue to thrive in their underground home. Susan and her friends end up destroying the Super Porp Factory and freeing the hyooman baby they had kidnapped. [S06E29 Dark Purple]
To celebrate Finn's thirteenth birthday, Jake organises a fake murder mystery on board a train. He fakes his own death and disguises himself as the conductor of the train, who is the "murderer". Finn fights the conductor using the Root Sword until Jake reveals that the whole thing was a set-up. Finn continues using the Root Sword as a replacement for Scarlet, which was lost when Finn dropped it into his black hole. [S03E19 Mystery Train, S02E15 The Real You]
Note: "Root Sword" was a name invented by fans, but it was later canonised by The Enchiridion & Marcy's Super Secret Scrapbook and Finn & Jake Investigations.
Later that year, on Jake's birthday, Finn attempts to pull a similar stunt in revenge. He invites several people to a mansion (Princess Bubblegum, Cinnamon Bun, Lumpy Space Princess, BMO, Jake, and himself) to solve another fake murder case. However, Jake discovers his plan beforehand and decides to "flip the script" and trick Finn into thinking that the murders really were real by disguising Lady Rainicorn as a murderous ghost. Unbeknownst to either Finn or Jake, the mansion was once the hideout of the Bath Boy Gang. Due to the location's strong connection to Shoko, one of Finn's past lives, he sees real visions of her ghost. But due to all the layers of mistrust in the whole situation, Jake doesn't believe Finn when he tells him about the visions. Finn ends up storing the memory in his "vault". [Righteous Rules for Being Awesome, S03E12 The Creeps, S05E34 The Vault]
Oh yeah. The vault. That's where the stuff I can't handle goes.
Finn [S05E34 The Vault]
Fast forward to 999 AMB, when Finn begins having recurring nightmares about the ghost he saw in the mansion. In an attempt to stop Finn from destroying the kitchen every time he goes sleepwalking, Jake tries to use hypnosis to get into Finn's vault and figure out the root cause. Finn has a flashback to his past life as Shoko and learns that her unfinished business was the fact that she never returned the stolen amulet to Princess Bubblegum. Finn digs Shoko's corpse out from under the floorboards of the Tree Fort and gives the Blue Amulet back to Bubblegum, allowing Shoko to move on in peace and ending the nightmares. [S05E34 The Vault]
One day, Princess Bubblegum has a vision of the Lich while meditating. She takes Finn and Jake to see the amber prison where he is being held. While Bubblegum, Finn, and Jake are all protected from the Lich's telepathic powers, he is able to possess a snail that was riding on Finn's backpack. The snail cracks the amber enough for the Lich to seep out. He makes a mad dash for his Well of Power, with Finn and Jake in hot pursuit. Finn is armed with the Gauntlet of Billy and a sweater knitted for him by Bubblegum.
Finn, you have but one chance. While the Lich isn't at full power, you must smite him with this gauntlet. His only desire is to destroy life. If you fail, he'll kill everyone. Oh, there's something else that I want you to have. The Lich's lair is supposed to be cold. I just don't want you to get sick. Take this sweater. I made it myself. I'm not great at knitting but please wear it. I care about you, Finn.
Princess Bubblegum [S02E24 Mortal Folly]
Meanwhile, Ice King kidnaps Princess Bubblegum and chases after the heroes to seek their permission to marry her. When they arrive at the Well of Power, Finn battles the Lich. The gauntlet is completely ineffective, but the sweater, imbued with what Finn calls "the power of liking someone a lot", is able to defeat him. All appears to be resolved until Ice King accidentally drops the princess into the well. [S02E24 Mortal Folly]
Princess Bubblegum is revived by her nurses and doctors, but Finn and Jake soon realise that she is possessed by the Lich. With Ice King's help they defeat the Lich for the second time, but almost kill Princess Bubblegum in the process. After reconstruction, there isn't enough candy biomass to restore Bubblegum to her usual physical age, so she technically becomes thirteen years old; the same age as Finn. The Lich, meanwhile, retreats to his snail form and begins to fabricate a new plan. [S02E25 Mortal Recoil]
By Candy Kingdom law, Princess Bubblegum is now too young to rule the kingdom. The next in line to the throne is none other than the psychopathic Earl of Lemongrab, who arrives at the castle to claim his leadership. Free of her responsibilities, Princess Bubblegum chooses to enjoy being a kid again. For the first time, she begins to reciprocate some of Finn's feelings for her, even sharing a kiss. However, the Earl unsurprisingly proves to be an awful ruler so Bubblegum uses donated candy biomass from her own citizens to re-age herself, and takes back the throne. To Finn's disappointment, their relationship returns to its usual platonic state. [S03E05 Too Young]
Marceline's ex-boyfriend Ash tricks Finn and Jake into erasing the memory of their breakup, but Finn is able to restore it and they break up a second time. Finn and Jake get glimpses of Marceline's complex past, including her experience shortly following the war, the fry incident, and when she moved into the Tree Fort. Ash is later arrested for fencing stolen property, impersonation, memory stealing, and "being a general pain in the butt". [S03E03 Memory of a Memory, The Adventure Time Encyclopaedia]
Later on, the most treasured possessions belonging to Finn, Jake, Bubblegum, and BMO are stolen by a door lord; a creature who is capable of conjuring magical doors. Their possessions are locked behind one such door, and the only way for them to retrieve them is to perform a song as a "genuine band". Along with Marceline, they eventually manage to open the door once Finn realises that the key is being truthful. It is revealed that the shirt Marceline gave to Bubblegum at the punk show is still her most treasured possession. It is also revealed that Marceline hadn't had anything stolen from her, and simply wanted to hang out with the others. Marceline and Princess Bubblegum begin to reconcile and become friends again after this.
Well, I shouldn't have to justify what I do
I shouldn't have to prove anything to you
I'm sorry that I exist, I forget what landed me on your blacklist
But I shouldn't have to be the one that makes up with you, so
Why do I want to?
Marceline singing I'm Just Your Problem [S03E10 What Was Missing]
The item stolen from Finn was the lock of Princess Bubblegum's hair. He begins to question what his actual relationship is towards Bubblegum, and eventually accepts that they can be good friends even if they remain platonic.
What am I to you?
Am I a joke, your knight, or your brother?
What am I to you?
Do you look down on me 'cause I'm younger?
Finn singing My Best Friends in the World [S03E10 What Was Missing]
The five friends subsequently often meet up for further "jam sessions" where they practice their music together. Jake helps push Marceline to stardom by writing about her music in Begs the Question, his newspaper column. Princess Bubblegum even joins a tour of Marceline's band (the Scream Queens) as their manager, and leaves Finn and Jake temporarily in charge of the Candy Kingdom. [S03E21 Marceline's Closet, S04E06 Daddy's Little Monster, Adventure Time #40: "Axe Before Taking", Finn & Jake Investigations, The Adventure Time Encyclopaedia, Marceline and the Scream Queens #1]
Clarence, the man who accidentally killed Warrior Princess, has become depressed and resorts to overeating. He commits suicide by eating too much Softy Cheese in the Squeez-E-Mart that was built on the same wind farm where the fateful battle had taken place. Jake witnesses this event and it puts him off eating Softy Cheese. Just like Warrior Princess, Clarence loses his mortal memories and is cursed to haunt the mortal plane as a ghost until he can discover how he died.
Ghost Princess and the ghost of Clarence end up falling in love a second time without remembering that they knew each other when they were alive. Finn and Jake successfully figure out that Clarence was Warrior Princess' accidental murderer by digging up both of their bodies and discovering the two halves of Clarence's knife. Jake also remembers seeing Clarence die in the Squeez-E-Mart. Having both discovered how they died, Ghost Princess and Clarence happily ascend to the Fiftieth Dead World together. [S03E24 Ghost Princess]
One account states that Ghost Princess was brought back from the Dead Worlds by the Ice King under the false impression that his romance would "make her feel alive again". [Marcy & Simon #1]
Finn and Jake discover a holo-message player in their attic after their dead father's "spirit sparkles" guide them there. In the first message, Joshua tells them about the dungeon he built to store Kee-Oth's Demon Blood Sword, and challenges them to take it on. Joshua believes that Finn is too much of a baby and designs the dungeon to "toughen him up" even though Finn has already matured since the message was recorded.
In order for Finn to stop whining, he needs to be put through a trial that forces him to take charge of a situation.
But Dad, Finn's already figured that out. He's a good kid with a kind heart.
Remember Jake, this is a pre-recorded holo-message. I can't hear you if you're talking to me right now.
Joshua's recording and Jake [S03E25 Dad's Dungeon]
Finn defeats the final monster of the dungeon and realises that Joshua was only trying to toughen him up because he loved him. Finn obtains the Demon Blood Sword and begins using it as his main weapon, replacing the Root Sword. [S03E25 Dad's Dungeon]
Finn falls into a depression after realising that he has no chance with Princess Bubblegum. Jake tries to lift his spirits by finding him a new love interest his own age, and ends up travelling to the Fire Kingdom to try to convince Flame King to let Finn court his daughter; Flame Princess, the Fire Elemental. His mission is successful, but he discovers too late that Flame Princess is actually, according to her father, evil. So Jake tries to break off the relationship before it begins. All this does is make Flame Princess confused and angry. She chases Jake back to the Tree Fort and meets Finn for the first time, where she slaps him and then leaves. Even though this first meeting isn't exactly romantic, and even though Finn has no idea what's happening, it's love at first sight for him. [S03E26 Incendium]
Finn and Jake track down Flame Princess and discover that she is planning to turn the Goblin Kingdom into her own new fire kingdom. They build fire-proof suits with Neptr and confront the princess. After Finn has an emotional breakdown, Flame Princess sees his tears and believes him to be a water elemental; her natural opposite. This causes her to realise that Finn must really be in love with her.
Finn, even if we like each other, we're going to hurt each other.
No, we don't have to. I can take it! I... I mean... can't we try?
You would defy nature for me?
Uh... yeah. Whatevs.
Flame Princess and Finn [S04E01 Hot to the Touch]
Finn and Flame Princess begin dating, and Finn builds her a new house away from the Fire Kingdom. However, Princess Bubblegum soon finds out about their relationship and recognises the danger that Flame Princess could pose if she is allowed to kiss Finn. Jake mistakes her concern for jealousy and makes no effort to prevent Finn and Flame Princess from seeing each other.
This isn't about some petty love triangle! Flame Princess is physically unstable! Her elemental matrix can't handle extreme romance. Glob, if Finn tries to kiss her, she'll burn so hot she'll melt right through the planet's crust, down through the molten core, then she'll be thrown back and forth by gravity until she burns out the world from the inside! Why do you think I had her father keep her locked up?
Princess Bubblegum [S04E16 Burning Low]
Finn and Flame Princess kiss and begin to fall through the crust, but Jake is able to block the hole and deprive the reaction of oxygen. Flame Princess is stabilised for now. She and Finn continue seeing each other and they figure out how to hug and kiss without hurting each other. Finn and Jake also foil an attempt on her father's life by Furnius and Torcho, his betrayed nephew and niece. [S04E16 Burning Low, Playing With Fire, S04E22 Ignition Point]
After being reunited with her father, Marceline begins to make more frequent trips to the Nightosphere to go and visit him. Hunson offers Marceline the opportunity to take over the "family business" from him and become the new Lord of Evil and ruler of the Nightosphere, but she refuses. [S04E06 Daddy's Little Monster]
One day, Marceline invites Finn and Jake to join her in the Nightosphere for a jam session. While they are playing, Hunson Abadeer tricks his daughter into wearing an amulet which forces her to become the new Lord of Evil and ruler of the Nightosphere. She knocks out Finn and Jake and gives them amnesia, and they wake up in a jail cell in the Nightosphere with no memory of where they are or how they got there. They wait in queue to see the Lord of Evil for twenty-seven days and eight hours and eventually escape the Nightosphere via a portal in Hunson Abadeer's castle. [S04E05 Return to the Nightosphere, S04E06 Daddy's Little Monster]
Safely back at the Tree Fort, Finn and Jake learn what happened via videos that Jake took with his camera phone, and Finn decides to rescue Marceline from the amulet. They re-enter the Nightosphere disguised as demons and manage to convince the other demons to start an uprising against the Lord of Evil. Finn yanks the amulet off Marceline's neck and wears it himself to help them escape, until Hunson intervenes and takes it back off Finn. Marceline, Finn, and Jake all escape back to the Land of Ooo. Hunson seems to realise that what he did was wrong, and he mostly stays out of his daughter's way from that point onwards.
I'm sorry. But I thought you'd wanna make your old man proud, and y'know... take over the Nightosphere.
Yeah, I want you to be proud. I want you to be proud of me.
No, I didn't mean... Baby, of course I'm proud of you.
Hunson Abadeer and Marceline [S04E06 Daddy's Little Monster]
Later on, the Nightosphere is one of the locations where Marceline and the Scream Queens play during their tour. Hunson meets Princess Bubblegum for the first time. [Marceline and the Scream Queens #5]
As princess of Candy Kingdom, I'm in charge of a lot of candy people. They rely on me. I can't imagine what might happen to them if I was gone. And after my brush with death at the hands of the Lich, I realised something: I'm not gonna live forever, Finn. I would if I could.
Princess Bubblegum [S04E10 Goliad]
Princess Bubblegum decides to engineer a new replacement ruler for the Candy Kingdom, much like she did when creating the Earl of Lemongrab many years earlier. This new creation is a Candy Sphinx containing her own DNA who she names "Goliad". However, Goliad cannot learn how to be a good ruler, instead resorting to her mind control powers to keep the candy citizens in check. To prevent her from taking over the kingdom, Bubblegum creates a new sphinx, but this time she uses Finn's DNA instead of her own. Due to his heroic attributes, the new sphinx (named "Stormo") enters a psychic showdown with Goliad which ends in a stalemate. They remain locked in mental combat on the roof of Bubblegum's castle for many years to come. [S04E10 Goliad]
The fact that Finn's DNA caused Stormo to be good implies that Bubblegum's DNA was one of the things which caused Goliad to go bad. As previously discussed, Bubblegum had a malevolent past while ruling the early Candy Kingdom. The casual way in which she tampers with the life she creates hints at the paranoid need for control she previously expressed all the way back at the foundation of the kingdom; an attitude which is mirrored and taken to the extreme by Goliad. [S04E10 Goliad, S10E04 Bonnibel Bubblegum]
Bubblegum also demonstrates her need for control after Cookie takes several of her citizens hostage inside a convenience store and demands her crown. Bubblegum wants to have Cookie permanently locked up in the dungeon for this crime, but Jake comes to see Cookie's point of view and tries to help him escape. The escape is unsuccessful, but Cookie ends up going to a mental hospital rather than the dungeon.
Princess Cookie's a good guy. He just got dealt a bad hand.
Jake [S04E13 Princess Cookie]
Finn and Jake learn about her surveillance network later that year after two banana guards show it to them. It is also revealed that Bubblegum has implanted a GPS tracker in Finn's ear so she can monitor him as well, and she has implemented extensive surveillance beyond the jurisdiction of her own kingdom. [S04E20 You Made Me, S04E19 Lady & Peebles, S06E22 The Cooler]
Despite claiming undifferentiated love for all her subjects, this love appears to be superficial as Bubblegum shows little respect towards their individual freedoms, treating them as playthings rather than as people. After Finn and Jake discover her cloning machine, it is revealed that she routinely clones her subjects whenever they get lost or "die", often at the expense of the original. [Hey Ice King! Why'd You Steal Our Garbage?!!, S05E42 James, S06E35 Graybles 1000+]
Her stubborn nature and her rejection of the concept of magic also put her at odds with the magical community of Wizard City. She serves jail time in wizard prison for entering the city as a none magic user and arguing with the Grand Master Wizard, but she manages to break out. This event is presumably detrimental to her diplomatic relationship with the city. [S05E26 Wizards Only, Fools]
Several dangerous criminals suddenly escape from the Candy Kingdom's underground dungeons, so Princess Bubblegum has her allies explore the dungeon to find out what's going on. Eventually, they discover that the Mother Gum, who has been locked up for centuries, has seeped into the structure of the dungeon and weakened the doors, allowing the prisoners to escape. The explorers find themselves forced to fight the Mother Gum, and after the battle it is unable to remain bound as one entity. The Mother Gum disperses into hundreds of pieces. [Explore the Dungeon Because I DON'T KNOW, Adventure Time Comics #20: "Hamilton"]
It means a lot you went to so much trouble to help me. I just wish you could have done it without killing my parents.
Princess Bubblegum [Explore the Dungeon Because I DON'T KNOW]
Note: The characters who explore the dungeon depend on who the player chooses, and could be any combination of Finn, Jake, Marceline, Ice King, Cinnamon Bun, Flame Princess, Lumpy Space Princess, Lemongrab, Peppermint Butler, Gunter, and Abraham Lincoln. The fact that Abraham Lincoln is present in the DLC and the post-credits scene suggests that the game takes place before Sons of Mars.
Bubblegum's old creation, the Gum creature which she created at the same time as the Earl of Lemongrab, also terrorises the Candy Kingdom until Bubblegum and her friends are able to pacify it. [Adventure Time #21 to #24]
Magic Man has spent the two hundred years of his banishment being a jerk to the people of Ooo. He meets Finn and Jake and turns Finn into a giant foot for no reason other than to prove to them how much of a jerk he is. [S01E20 Freak City]
By the end of Magic Man's banishment, he still hasn't managed to activate his Martian transporter because he still has no friends who he cares about, and he falsely believes that it's broken. Grob Gob Glob Grod returns to Earth to retrieve Magic Man for his trial. However, Magic Man switches bodies with Jake. Glob takes Jake back to Mars instead of Magic Man, and Finn uses the transporter to follow them in an attempt to rescue his friend. Abraham Lincoln, the King of Mars, sentences Magic Man to death and Jake is mistakenly killed instead. This fulfils the prophecy that Jake and Lincoln would meet.
This wouldn't have globbed if you'd just listened to my bro. You bunked up, King of Mars. The wisest, most honest super-being of all time just put an innocent dog to death.
Finn [S04E15 Sons of Mars]
Ashamed by his lack of judgement, Lincoln travels to the thirty-seventh Dead World to retrieve Jake from Death. But Death is not willing to return a life for nothing.
Not this time, your majesty.
Death [S04E15 Sons of Mars]
In return for Jake's life, Lincoln chooses to sacrifice his own immortality. He is transported back to his original time of death and killed by the bullet that was always destined to end his life. Jake is saved, but Mars loses its leader and Magic Man gets away with no repercussions. However, he is still trapped on Earth for now. [S04E15 Sons of Mars]
Still trapped in snail form, the Lich recruits a bear to retrieve the Enchiridion from Finn and Jake. The bear does this by pretending that he wants to be a hero. Feeling pity for him, Finn and Jake give away the book.
Whatever man. We never use it. Except for, like, sitting on it when the grass is wet and stuff.
Finn [S04E07 In Your Footsteps]
Once the Lich obtains the Enchiridion and regains his physical form, he murders Billy and begins wearing his skin as a disguise. He tricks Finn and Jake into helping him collect the Gems of Power from the various royal crowns of Ooo, including Princess Bubblegum's. Finn and Jake only realise the Lich's true identity after the Gumball Guardians attack him and burn off some of Billy's skin, but by this point it is too late. The Lich inserts the gems into the front cover of the Enchiridion and opens a portal to the Time Room. Finn and Jake manage to follow him through. [S04E26 The Lich]
The three of them all arrive in the Time Room, and as a result they are each granted one wish by the almighty Cosmic Entity Prismo. The Lich wishes for the destruction of all life, and he is transported to his own wish-altered reality where that wish has come true. However, since the Time Room exists outside of time, it is unaffected by the wish until Finn and Jake also make their own wishes. Finn wishes that the Lich never existed, and he is also transported to his own wish-altered reality, known as Farmworld. [S05E01 Finn the Human]
There is still a nuclear war in 0 AMB. However, rather than meeting after the war, Marceline and Simon become friends beforehand, and Marceline is able to assist Simon in his battle with Evergreen's crown. He remains sane enough that he succeeds in completely stopping the Mushroom Bomb using his ice powers. Unfortunately he is crushed to death under the weight of the frozen bomb, and Evergreen's crown grieves its fallen master by plunging the world into an apocalyptic ice age. The Blue Catalyst Comet misses the Earth and never delivers its Agent of Change. Marceline never becomes a vampire and therefore ages into an old woman, but is kept alive for the next thousand years by her demon physiology. She guards the crown and Simon's body.
One thousand years ago, my beloved friend Simon Petrikov gave his life to save this foolish unworthy planet from annihilation. Frightful bombs poised to bathe the land in mutagenic horror. But using his mastery of ice and snow, Simon froze the bomb in mid-flight; only inches from the ground, where it remains to this very day. Today, ever ripe and ready to blow. But he alone was not saved. Trapped under the giant weight of the enormous bomb, poor Simon perished. Then the horrible crown, grieving its lost master, loosed a spasm of magic so wild and crazy the entire Earth was buried in ice for four hundred boring years.
Farmworld Marceline [S05E01 Finn the Human]
By 984 AMB, the world has thawed out and humanity has redeveloped into a medieval society. Finn Mertens, just an ordinary human rather than an Agent of Change, is born in Junk Town. He lives with his two biological parents and his younger sibling. [S05E01 Finn the Human]
By 998 AMB, a band of outlaws who call themselves Destiny Gang rule over Junk Town. Finn's father ends up owing them money, so his mother sends Finn into the town to sell their mule. Finn discovers Marceline and steals Evergreen's crown, believing he can sell it and avoid having to sell his beloved mule. However, Big Destiny, leader of Destiny Gang, refuses to allow the debt to be paid off and instead burns down Junk Town and the Mertens household. Finn uses the power of the crown to attack Destiny Gang to save his family. His actions accidentally lead to the thawing of the Mushroom Bomb. It detonates, killing Marceline and many other humans, and releasing the Lich despite the original wish. [S05E01 Finn the Human, S05E02 Jake the Dog]
Meanwhile, Prismo, Jake, and the Cosmic Owl are left alone in the Time Room. Jake initially loses focus and almost wastes his wish to create a sandwich, but once he has befriended the Cosmic Entities, Prismo begins to guide him towards the wish that will save the Multiverse.
Look, I like you, so you should know my wishes always got an ironic twist to them. It's like a monkey's paw kind of thing. You just gotta be really specific. Say your wish is "I wish for a back rub". Who's gonna give it to you? A dirty man? A bear? And where does this masseuse come from? Do I zap some guy away from his family dinner? Leave some kid traumatised? You see, Jake, there are rules to this stuff. Wishing an event to be changes elements before and after it. Memories will be destroyed, babies will not be born. Potential worlds could be evaporated by your wish!
Prismo [S05E02 Jake the Dog]
Eventually, Prismo basically makes Jake's wish for him. He wishes to overwrite the Lich's wish so that instead of wishing for the destruction of all life, the Lich wishes to send Finn and Jake back to Ooo. The Farmworld timeline is erased, although it persists as its own dimension where a version of the Lich still resides. In addition to this, the main timeline Lich becomes helplessly trapped in the Time Room having wasted his one wish. He eventually submits to the situation and remains stood in Prismo's room like a statue, waiting for his next opportunity. [S05E02 Jake the Dog, S07E23 Crossover, S06E01 Wake Up]
Finn and Jake arrive back in Ooo and Finn has no memory of the events that occurred in Farmworld. The Gems of Power are returned to the royal crowns and Prismo drops a note to Earth inviting Jake to hang out with him again. [S05E02 Jake the Dog]
At some point, Jake and Lady Rainicorn have a very good time on the swan ride at Thrashland. [S08E16 Wheels]
After Finn and Jake go missing for three weeks, Princess Bubblegum and Lady Rainicorn set out on a mission to rescue them. It turns out Ricardio has regained his independence from Ice King and kidnapped them. They defeat Ricardio and Bubblegum builds Ice King a new heart out of maracas and toffee. Lady Rainicorn reveals to Jake that the reason she was so worried about his disappearance was because she is pregnant with their hybrid children.
자기야, 나 완전 중요한 할 말 있어. 나... I am pregnant!
Lady Rainicorn [S04E19 Lady & Peebles]
Lady gives birth to a litter of five pups; Charlie, T.V., Viola, Kim Kil Whan, and Jake Junior.
Jake is initially overprotective of their children and chooses to strictly follow his mother's childcare manual rather than allowing them to have their own freedom to explore and discover. His protectiveness is especially pointless given that the pups mature at an extremely rapid rate and are effectively adults after just one day of life.
It turns out the pups can pretty much take care of themselves. They don't really need me around. I guess rainicorns age really fast. They're basically like older than me already. Kil Whan has a beard now.
Jake [S05E06 Jake the Dad]
Jake ends up swinging to the complete opposite end of the spectrum and becomes a neglectful parent. T.V. claims during the pups' first birthday party that he has only met his father twice. Jake is also three hours late for that party and forgets to bring presents for any of his children. [S06E12 Ocarina]
All of the pups go on to establish their own unique lives.
Although it will not become apparent for a while, the pups' unmatched magical powers and incredibly fast ageing process put them on the path towards becoming the dominant species in Ooo. There are also considerations being made about containing or harnessing their power from quite an early point in their existence. [S10E13 Come Along With Me Part 1]
Your daughter's teleportation power though; it consumed no components, nor needed incantation. I would love to run some experiments, extract that ability from her.
Peppermint Butler talking to Jake [Adventure Time #41]
In 996 AMB, the Goblin Kingdom is ruled by a tyrannical king named Xergiok who had an unhealthy addiction to spanking his subjects. Finn and Jake defeat him and exile him into the desert. Finn is crowned the new king, but he and Jake install Whisper Dan as a placeholder and leave the goblins to rule themselves. [S02E14 The Silent King]
In the following year or so, Xergiok somehow loses his eyes and goes blind. He claims that they were stolen by a wizard, not realising that they are in fact just stuck in his beard. He begins living in the Rookery where he looks after his giant birds and becomes known amongst the people of Ooo as the rumoured "Great Bird Man". As a changed man, Xergiok puts other people ahead of himself, even donating his kidneys to a hospital.
When we first met, I was crazy for smacking goblin hams. I was cruel, selfish, brutal. But everything changed after I was defeated by the two of you! I miffed off a wizard, and he took my eyes. I wonder what he wanted them for. Some kind of lotion, or potion, or time travelling spell. I'll never know. But losing my eyesight was only the beginning of my wonderful change! I started meditating and doing yoga. Now I can see with my heart and smell with my soul.
Xergiok [S05E13 The Great Bird Man]
Princess Bubblegum dispatches Finn and Jake to track down the Great Bird Man while she deals with a group of depressed mermaids. After Finn and Jake meet the Great Bird Man and discover his true identity, they decide that he really has changed, and they return his eyes to him. However, he almost immediately reverts back to his old ways, threatening to retake the Goblin Kingdom. He is abandoned by his birds for his rekindled cruelty. Alone and realising the error of his ways, he chooses to remove his own eyes once again, and then walks into the Goblin Kingdom's reservoir to drown himself. However, he is rescued by one of the mermaids, who falls in love with him. [S05E13 The Great Bird Man]
Over time, Finn begins to develop something of a selfish personality which probably stems from his absolute view of good and evil and his belief that he is an infallible hero. This trait is first seen when Finn forces his own weird fantasies upon the little people secretly given to him by Magic Man, with disastrous consequences. He also begins to become tired of his growing fame in the Candy Kingdom, causing him to disguise himself as Davey for a while; his unremarkable alter ego and past life. [S05E05 All the Little People, S05E07 Davey, Adventure Time #50]
Meanwhile, his relationship with Flame Princess is ongoing. Finn takes her through a dungeon and uses it to convince her that she isn't evil, despite her father's intentions to the contrary. However, the dungeon also begins to reveal that Finn and Flame Princess share different interests, and Finn begins to get hung up on a lot of what Jake calls "imaginary problems" in their relationship. It is at this time Finn travels into "Pillow World", a possibly imaginary alternate timeline, and returns with no memory of what happened while he was there. [S05E12 Vault of Bones, S05E16 Puhoy]
Finn arrives alone in Pillow World and becomes hero of a town after slaying a blanket dragon. Since the exit back to the real world seals itself behind him, he is trapped in Pillow World. Seeing no way out, he settles down and begins leading a new life there. He falls in love with Roselinen, the daughter of the town's mayor Quilton.
Finn and Roselinen marry and have two children named Jay and Bonnie, named after Jake and Princess Bubblegum. Quilton visits their home and tells Finn that he has discovered evidence of a doorway leading back to the real world. Finn begins to dedicate his life to finding the door.
Archaeologists found this in the Pillow Catacombs. The Pillownomicon. There is no information about the door, save for the fact it shows up periodically then disappears.
Quilton [S05E16 Puhoy]
By now an elderly man, Finn visits Rasheeta the Oracle in his continuing quest to find the door back to his own world. She merely tells him that there is "not long now" until he will be able to return home.
Oh Finn. I know you have to go. All these years, I've known. But now that it's time... Oh man, well I'm just all messed up about it. Just promise me you'll remember us when you're back in your real life.
Roselinen [S05E16 Puhoy]
Finn decides to remain with his new family, since he's known them for longer by this point than anyone back in the real world. After a lifetime spent in Pillow World, Finn dies of old age. He narrowly avoids falling into the maw of GOLB and emerges from the pillow fort back in the real world, restored to his young body. Despite Roselinen's wish, he immediately forgets everything about his life in Pillow World and continues as if nothing ever happened.
Note: Pillow World is implied to be real in Marcy & Simon #5, but it remains unknown whether or not Finn actually remembers the life he lived there or if he just vaguely remembered that it was a place that existed.
A fortune teller informs Flame Princess that she is going to suffer a loss in the future, referring to the fact that she was planning on stealing Finn's soul. However, the fortune turns out to have further implications for their relationship later on. [Playing With Fire]
Meanwhile, Finn seems to harbour a slight feeling of bitterness towards Princess Bubblegum for the way their relationship panned out, but he never entirely loses interest. He expresses slight jealousy after learning that Braco is "courting" the princess, even though he himself is dating Flame Princess at this time.
That road you are on... leads to nowhere.
Finn talking to Braco [S05E21 The Suitor]
Eventually it all unravels. After witnessing two battles between Flame Princess and Ice King, he begins to have a certain type of dream about her. The Cosmic Owl is present, meaning they are prophetic dreams, and Jake convinces Finn that he needs to force himself to have the dream again so that he can hear the full prophecy. Finn forges letters from Ice King to Flame Princess and vice versa, in which they challenge each other to a final fight. During the resultant battle, the Ice Kingdom is almost completely destroyed by Flame Princess' attacks and its residents are forced to evacuate. Thankfully, the underground structures of the kingdom like the "The Past" room and the secret library are left intact. Finn faints from the heat during the battle and completes the prophetic dream, but the prophecy is only three words long.
You blew it.
Cosmic Owl [S05E30 Frost & Fire]
After the battle, Finn admits to Flame Princess that he had planned it all. She officially breaks up with him not long after. The prophecy is self-fulfilling. Ice King, now homeless, moves into the Tree Fort with Finn and Jake while he lends the Crown to his penguins so they can rebuild the Ice Kingdom. [S05E30 Frost & Fire, S05E31 Too Old, S05E32 Earth & Water]
Following her breakup with Finn, Flame Princess begins to develop serious trust issues. She volunteers to take part in Princess Bubblegum's research into her "elemental matrix" because she believes it will be able to cure her complex emotions, but the test is interrupted when Bubblegum has to go and help Finn and Jake deal with Gunter, who has used the Crown to rebel against Ice King. Bubblegum leaves her goofy "half baked" assistant Cinnamon Bun to oversee the rest of the test. Cinnamon Bun releases Flame Princess from the test chamber, and she is charmed by the simplicity and honesty of his life. Cinnamon Bun tells her about how it was Princess Bubblegum who had her locked up as a child, further compounding her trust issues. Finally, Flame Princess and Cinnamon Bun stage a coup in the Fire Kingdom and she takes the throne from her father. She installs a policy of absolute honesty for all citizens of the kingdom so that nobody is legally allowed to lie. [S05E32 Earth & Water]
Flame Princess takes the title of King and has her father locked up in the same lantern as she was imprisoned in for the first fifteen years of her life. This event fulfils the prophecy that Flame King's daughter would become more powerful than him. [S05E32 Earth & Water]
Finn is also feeling lost after the end of his first real romantic relationship, falling into a bit of a depression.
I've just been feeling kinda grey, is all. Like my inside voice has been kinda quiet lately. Not a lot of instructions forthcoming, y'know?
Finn [S05E36 Dungeon Train]
He takes refuge in the relative simplicity of places like the Dungeon Train and the Box Kingdom. He briefly crushes on Princess Bubblegum again but quickly realises that she is too mature for him, especially after learning that she is actually hundreds of years old, rather than nineteen as she has been telling him. For a while he decides to entirely devote himself to her as a loyal servant, but that doesn't work out either. [S05E36 Dungeon Train, S05E37 Box Prince, S05E31 Too Old, S05E34 The Vault, S05E46 Rattleballs]
I'm thinking maybe age isn't just a number. Maybe older people, like, really are different. Y'know, like, less fun inside.
Finn [S05E31 Too Old]
While he is in this funk he also gets a poorly timed marriage proposal from Slime Princess, who needs a named husband in order to remain a legitimate heir to the throne to prevent her evil sister Blagertha from militarising the Slime Kingdom. It is unclear whether or not Finn and Slime Princess actually remain married after Blagertha's plans for conquest are foiled. [S05E35 Love Games]
After Flame Princess has been ruling for some time, her father secretly organises a deal with his old friend Don John the Flame Lord, who agrees to help him escape the lantern if he grants him his daughter's hand in marriage. Don John arranges for Flame Princess to be poisoned by her servant Ursula, and succeeds in returning the Red Throne to Flame King while she is weakened by hypnotising the Flame King's guards and court. Flame Princess chooses to go to Finn for help on strictly platonic terms.
Listen, Finn. This doesn't mean we're getting back together. We're all business.
Flame Princess [S05E47 The Red Throne]
Predictably, Finn lets his residual feelings for Flame Princess interfere with the mission to retake the kingdom. They end up getting captured by Don John and Flame King. However, a fight breaks out between them and Flame King knocks out Don John. In the resulting confusion and the lifting of the hypnosis spell, Cinnamon Bun is able to rescue Finn and Flame Princess. During the rescue he takes a blast of fire to the face, causing him to become "fully baked" and gain a great deal of maturity. After imprisoning Flame King and Don John and re-installing Flame Princess on the throne, Cinnamon Bun pledges his allegiance to Flame Princess and becomes her champion.
Flame Princess may not be the most ruthless of all despots, but she is strong where it really counts; in her heart. And that is good. I have learned so much watching this beautiful woman work, and with her example, I have become a better man. I will be by her side as her champion and knight every step of the way, because... I love her.
Jeez. Did I just get shown up by Cinnamon Bun?
Cinnamon Bun and Finn [S05E47 The Red Throne]
Some of the other kingdoms continue to develop during this time. Most notably, the Wildberry Kingdom and the Breakfast Kingdom are seen to undergo rapid expansion over the course of the series. [S06E08 Furniture & Meat, S06E14 Princess Day]
Princess Bubblegum resolves the conflict between the Sea Caves, the Mountain Pass, and the Spirit Hollow at around this time, and also sends Finn and Jake to solve a leadership crisis in the Nameless Kingdom. They resolve it by choosing Nightmare Princess to rule rather than either of her two sisters. [Bitter Sweets, Secret of the Nameless Kingdom]
Note: Finn & Jake Investigations confirms that the Nightmare Princess ending is the canon ending to Secret of the Nameless Kingdom. The final form of Nightmare Princess in SotNK looks very similar to Nightmare Princess from the episode Orb. This appears to be the show acknowledging the existence of the Nameless Kingdom, but might also suggest that the game is non-canon since Finn does not recognise the princess when they meet in Orb.
After getting tired of Ice King crashing in the Tree Fort, Finn and Jake invite Abracadaniel to stay so that he can befriend Ice King and hopefully get him out of their hair. The plan works, but backfires horribly when Ice King accidentally summons the demon Kee-Oth while showing off the Demon Blood Sword to his new friend. Kee-Oth forces Finn and Jake to return his blood, destroying the Demon Blood Sword, and then kidnaps Jake under the false belief that he is Joshua. [S05E40 Play Date]
Meanwhile, Abracadaniel and Ice King run away to the Ice Kingdom, which it turns out has already been repaired; Ice King was just enjoying his time at the Tree Fort.
I thought your house broke.
Pfft, Ice Kingdom's been rebuilt for weeks!
Abracadaniel and Ice King [S05E40 Play Date]
Kee-Oth wants to keep Joshua prisoner in his home realm, the Broke-Up Dimension, as revenge for Joshua stealing his blood in the first place, and is disappointed when he finds out that Joshua is already dead and he has instead kidnapped his son. He is also put off by Jake's passive attitude towards the whole situation, claiming that his father would have put up a better fight. Nevertheless he continues to keep Jake prisoner and forces him to fight with another prisoner named Samantha.
Meanwhile on Earth, Finn calls Lady, who is able to find some old tapes of Joshua detailing the ritual for travelling to the Broke-Up Dimension where Kee-Oth resides. They travel to Cave 73H of the Underground Grasslands Complex and recover a magical tablet which they are able to use to transport them there. Finn brings a fake demon blood sword made of frozen grape juice (blessed by Shelby to give it the properties of holy water) and tricks Kee-Oth into absorbing it. Kee-Oth is killed by the holy grape juice and Finn, Jake, Lady, and Samantha all return to Earth. [S05E41 The Pit]
Over the course of the past few years, the technological level and affluence of the Candy Kingdom has been slowly rising. Modern mechanical vehicles like cars, underground trains, aeroplanes, and helicopters have seen a considerable rise in popularity, and the Candy Kingdom has developed a bustling down-town area complete with offices and a theatre district. The decorpsinator serum is developed following the two zombie invasions, and the Spoon of Prosperity (an item with magical healing powers) is recovered from an ancient city which was turned to sand by an evil wizard named Paris. Both of these make the candy people a very secure and prolific species. [S05E43 Root Beer Guy, S05E25 Candy Streets, S07E16 Summer Showers, S01E01 Slumber Party Panic, S05E38 Red Starved]
Peeps'll never starve in my eternal empire.
Princess Bubblegum [S05E38 Red Starved]
Princess Bubblegum even begins development of a space program after Marceline gets blasted out to the asteroids. [Marceline Gone Adrift #3]
So... you invented space travel just for me, huh?
Marceline talking to Princess Bubblegum [Marceline Gone Adrift #6]
Princess Bubblegum seeks to further expand her kingdom into new unexplored territories; notably, the Desert of Wonders, a condemned area of pre-war ruins which has been left mostly untouched since the Mushroom War. She leads a small expedition into the desert to collect samples, saying she wants to begin colonising the area by the end of the year. Accompanying her on the expedition are Finn and Jake, as well as a candy person named James. Their vehicle ends up getting disabled by some of the oozers which still inhabit the remains of the old city. James sacrifices himself so that the others can escape and gets turned into an oozer, but Princess Bubblegum is able to use a piece of his flesh to clone a new version of him once they get back to the Candy Kingdom. He is awarded a medal for bravery. [S05E42 James]
Later on, the new James fakes his own death by performing "selfless acts" twenty four times in order to keep getting awarded medals and keep getting cloned, saying he likes his own company. His scheme is eventually foiled by Princess Bubblegum. However, the original James, who became an oozer, happens to attack the Candy Kingdom at this time along with a load of other oozers. Wanting to prove that they really are heroes, all twenty five James clones leap onto the oozer and become amalgamated into one new entity. Bubblegum banishes them into the wasteland where they live in a tent. [S06E03 James II, S09E10 Abstract]
By the time of the series, Tree Trunks is living alone following her divorce from Wyatt, although she is also technically married to the grey aliens at this time. She befriends Finn and Jake, who often stop by her home to eat her famous apple pie. One day, they decide to help her find the Crystal Gem Apple, which is supposedly the rarest of all apples. The mission is successful, but when Tree Trunks bites the apple she appears to explode and die. [S01E04 Tree Trunks]
Unbeknownst to Finn or Jake, she is not actually dead. The Crystal Gem Apple drives her mad with power and she becomes a ruler in the Crystal Dimension under the name "Quartzium the Crystal Queen".
Oh, I'm more than alive, Finn. After I ate that crystal apple in the Scary Dark Forest, I was transported to this Crystal Dimension where I became ruler of the crystal men. And the crystal men are all in love with me.
Tree Trunks [S02E08 Crystals Have Power]
Some time later, Finn is kidnapped by people from the Crystal Dimension and it is revealed that they are working for Tree Trunks, who wants to make Finn her king. Jake manages to kick the apple back out of her stomach, reverting her back to normal. [S02E08 Crystals Have Power]
Following her foray in the Crystal Dimension, Tree Trunks' life returns to normal. One day she recruits Finn and Jake to try to work out who was stealing her apples, which leads them on a wild goose chase through the back streets of the Candy Kingdom until they are captured by a gang of criminals. Finn and Jake eventually realise that "apples" is slang for "diamonds" and their entire escapade has been pointless. However, they rescue a pig (named Mr. Pig) from the gang while they are escaping, and later discover that Tree Trunks' apples were actually being stolen by birds due to the fact that Raggedy Princess was no longer acting as her scarecrow. [S03E11 Apple Thief]
Mr. Pig is homeless and has nowhere else to go, so ends up staying in Tree Trunks' house. They eventually confess their love for each other.
Ma'am. Today, I wish to speak my feelings. When I see you, my heart beats like a choo-choo train. When you stand near me, I get so nervous I cannot move.
Shush. I feel the same. I have a feeling that this is the feeling others call... love.
Mr. Pig and Tree Trunks [S04E04 Dream of Love]
The next year, they decide to have a wedding; Tree Trunks' fifth. However, the event ends disastrously after Princess Bubblegum finds out that the officiator of the marriage will be none other than her hated rival, the self-proclaimed King of Ooo, who is still living the high life off the money Tree Trunks gave him after she sold her company. Bubblegum desperately attempts to find something she can arrest him for by snooping around in his airship while he is officiating the wedding, even though had she attended the ceremony she would have discovered that the entire event was merely a front for getting Tree Trunks and Mr. Pig to sign up to work in his labour camp.
Do you, Mr. Pig, take Tree Trunks to be your ever wedded wife, forever following the teachings of me, the True King of Ooo?
And do you, Tree Trunks; do you promise to love Mr. Pig forever, and spend the next five years with me in my "serenity compound", performing simple household repairs, to have and to hold, in sickness and in health, in my gated mountain compound?
King of Ooo [S05E44 Apple Wedding]
Luckily for Tree Trunks, Bubblegum quite literally crashes the wedding at this point, falsely believing that his officiator credentials are out of date. After finding out she is wrong, Princess Bubblegum tries to arrest the King of Ooo anyway. But she meets resistance from Tree Trunks, who says that she will have to lock up the entire congregation. So Bubblegum arrests every single attendee of the wedding and locks them in the dungeon. Fearing for his life, King of Ooo escapes the dungeon through a window, but it would not be the last the kingdom sees of him.
That loopy bird is gonna string me up sideways! You can perform your own dang ceremony!
King of Ooo [S05E44 Apple Wedding]
Tree Trunks and Mr. Pig take this as official permission to get married, and they complete the wedding in the dungeon cell. Bubblegum, watching through the security cameras, is so touched that she releases them. But Tree Trunks would never forgive her for ruining the initial ceremony. [S05E44 Apple Wedding, S08E17 High Strangeness]
Since the Demon Blood Sword was destroyed by Kee-Oth, Jake convinces Finn to go shopping for a new weapon. He buys a sword made of grass from Grassy Wizard for only three dollars. Obviously, there's a catch; it turns out to be cursed to bind to its wielder for all eternity. However, Finn decides that he doesn't mind this eternal curse; the Grass Sword is powerful and he quickly grows to love it.
Now that you've accepted it, you can control it.
Jake [S05E45 Blade of Grass]
While messing around with his new sword in the dump, Finn meets Rattleballs, who has been hidden there ever since escaping his execution centuries earlier. After Finn dislodges a gumball that has been lodged in an awkward spot in his throat, Rattleballs agrees to teach him how to use his sword properly. However, Finn feels that keeping Rattleballs' existence a secret would conflict with his oath to serve the princess, so he tells her about the hidden renegade. Believing that Rattleballs is still dangerous, Bubblegum travels to the dump with a squad of banana guards to destroy him once and for all.
You think I'm dangerous, princess? I no longer crave mindless violence. I have found peace in meditation, gardening, egg-throwing. I hope time has also made you less bloodthirsty, princess. But do with me as you will. In my heart I still serve you. One hundred percent.
Rattleballs [S05E46 Rattleballs]
Seeing that he has changed, Bubblegum grants him knighthood and orders him to watch over the Candy Kingdom from the shadows as its hidden protector. [S05E46 Rattleballs]
After Ice King visits Marceline for help writing lyrics, she discovers some of the old notes that he wrote to her and they perform them as a song. Although he is confused, Ice King seems to understand how much the notes mean to Marceline, and although he remains ignorant of his past, this small moment of reconciliation enables Marceline to begin to open up to her friends about the trauma left by his departure. She tells Finn and Jake the story of how they travelled together during the aftermath of the Great Mushroom War, and she begins to spend more time visiting the Ice King. [S04E25 I Remember You, S05E14 Simon & Marcy, S05E09 Bad Little Boy]
I suppose it's about time I told someone this story.
Marceline [S05E14 Simon & Marcy]
Marceline also ups her efforts to track down Maja the Sky Witch and retrieve her teddy Hambo, who was given to Marceline by Simon and sold to Maja by Ash. Marceline eventually tracks Maja to her home, and she and Princess Bubblegum embark on a mission to rescue Hambo. After Bubblegum learns that Hambo's sale was legitimate, she proposes a trade rather than taking him back by force. In exchange for Hambo, Bubblegum gives Maja her treasured rock shirt. It apparently holds an even greater sentimental value than Hambo; power which Maja uses to begin to enact her plan. But that's a story for later. [S05E29 Sky Witch]
A secret society in Wizard City makes a deal with an evil interdimensional anti-magical creature named Belle Noche in an effort to unlock the secrets of antediluvian magic. However, after the society summons her to Earth, she betrays them and begins to destroy the city. Its citizens fight back in full force, but with their magic negated there is very little they can do. One of the victims of the anti-magic is Ice King. It negates the power of Evergreen's crown and he suddenly reverts back to his previous form; Simon Petrikov.
This must be it, man. I've crossed into some new super-insane zone, where I feel like I'm just normal again... Or maybe I'm just normal again.
Simon Petrikov [S05E48 Betty]
Simon quickly realises that the crown was keeping him alive and without it he has begun to die of old age. He decides that before he dies, he must attempt to say one final goodbye to Betty Grof, his fiancée who mysteriously disappeared all those years ago. He runs into Ash and hijacks his flying carpet to fly back to the Ice Kingdom, where he retrieves his copy of Mystic Rituals and Their Space Time Applications, the academic book he co-authored with Betty, to find a way to open a portal to the past. He manages to rig up a rudimentary portal opener using a bicycle generator and a cauldron, and calls Marceline for her help.
Marcy, it's me, Simon. I'm back but my body might donk out soon so get to the Ice Kingdom fast and help me with this time portal so I can find Betty and say I'm sorry before I croak-boat. I know that's a lot to process but hurry, and bring Hambo! Hambo is the key... An object from the past that has been lovingly tended to through the ages.
Simon Petrikov [S05E48 Betty]
After sacrificing Hambo, the portal is opened and Simon is able to speak to a version of Betty from a thousand years in the past. Simon tells her that she disappeared after he wore the crown, and, realising why, she jumps through the portal and joins him in the future. After very rapidly being brought up to speed with current events, Betty rides the flying carpet back to Wizard City and flies it directly into the anti-magic, where she punches Belle Noche's lights out and restores magic to the city. Simon becomes the Ice King once again. [S05E48 Betty]
Seeing how he has been driven to insanity, Betty remains incognito and studies Simon from a distance, but still spends all her time trying to find a cure for his condition. [S06E38 You Forgot Your Floaties]
After his brief time as ruler of the Candy Kingdom, the Earl of Lemongrab realises how alone he has always been. Princess Bubblegum's surveillance network spots him standing in her citizens' bedrooms at night, watching them from dark corners. When confronted, he reveals that he likes to watch the candy people because he has no citizens of his own.
I am the Earl... the Earl of nothing! No one understands. I am alone. And you made me like this.
Earl of Lemongrab [S04E20 You Made Me]
Bubblegum appeals to her people and ends up sending Candy Kingdom youths from the Pup Gang to live with Lemongrab. But he treats them badly and tortures them with electricity, and continues spying on the other candy citizens anyway. Realising that he will never get along with her people, Princess Bubblegum constructs an exact clone of Lemongrab to keep him company. The two Lemongrabs co-rule peacefully for a while. [S04E20 You Made Me]
Unbeknownst to Bubblegum, she accidentally drops the secret formula for creating candy life in the pantry of Castle Lemongrab while creating the clone. The Lemongrabs end up turning all of their food into new lemon citizens to live in their earldom, quickly driving their new people into a famine. The largest of them is a lemon titan named Lemonjon, whose body and organs are distributed throughout Castle Lemongrab. They send a letter to Princess Bubblegum demanding more food, so she dispatches Finn and Jake to deliver some new seeds to them.
You see Finn, when Mother Princess last visited Lemongrab, she left behind a little something something. The secret formula for creating candy life. She must have meant for us to have it; to keep making more family. For once we had commenced how could we desist? I looked deep in myself and found that I'm a guy who can't stop making candy life from the food he needs. It just felt so pretty okay inside, greeting each new placid face and hearing each new piercing song.
The Earls of Lemongrab [S05E09 All Your Fault]
The earls decide that their best course of action is to invade the Candy Kingdom and pillage it for its food, so Lemonjon picks up the entire earldom and begins to march. However, Finn and Jake restart his heart, causing him to decide that the only good thing he can do is sacrifice himself and become food for all the other lemon people. Bubblegum erases the formula from the earls' minds, but lets them keep their new subjects. [S05E09 All Your Fault]
All is well for a while longer, until an argument breaks out between the Lemongrabs over their "son", a porcelain doll named Lemon Sweets, who is accidentally shattered during the disagreement. The original bites off half of his clone's face, and the symmetry of their rule begins to break down. Lemongrab Number One grows fat and ever more powerful while Lemongrab Number Two becomes thin and decrepit, unable to counteract the increasingly tyrannical rule of his brother. [S05E24 Another Five More Short Graybles, S05E32 Too Old]
During a diplomatic mission to the earldom, Princess Bubblegum and Finn discover a boy named Lemonhope who is unlike the other lemon people. He appears sweet and kind and he plays the harp. She states her intention to take Lemonhope back to the Candy Kingdom to give him a proper education, but Fat Lemongrab forbids it. Lemongrab Number Two takes some pity on the child and tries to help him escape. This pushes Fat Lemongrab over the scales, and he consumes his twin brother whole.
It has cost me much, but I have learned; lemon need not squeeze lemon to survive. Lemonhope: go forth. Grow strong and return for us. Go!
Lemongrab Number Two [S05E31 Too Old]
With help from the rebellious lemon citizens, Lemonhope returns to the Candy Kingdom with Princess Bubblegum. The rebellion of his people and the betrayal of his brother cause Fat Lemongrab to reduce his earldom to a totalitarian dictatorship where those who helped with the escape are punished, and those who try to escape for themselves are cannibalised. Lemongrab Number Two remains alive in his brother's stomach, begging for Lemonhope's heroic return. However, back in the Candy Kingdom, Lemonhope is reluctant to become the hero everyone expects him to be. Instead, he develops the same selfish attitude as his progenitors, eventually causing him to run away from the kingdom on a quest for true freedom.
They helped you. You have to help them now. It's your responsibility.
No! I don't have to do anything that I don't want to! They set me free, and free means I decide what I do, not them. And not you!
Princess Bubblegum and Lemonhope [S05E50 Lemonhope Part One]
After wandering the Land of Ooo for a while, Lemonhope stumbles across a town being raided by pirates and chooses to stow away on their ship. But the ship is attacked and abducted by a greed lard; all of the crew go missing in the battle, and the greed lard drops the ship in the middle of a desert. Lemonhope lives a lonesome life for a while, barely surviving on the short supply of rations left in the ship. He has frequent nightmares about his people back in the earldom. Soon, he collapses from the heat of the desert while out searching for water. [S05E50 Lemonhope Part One]
Lemonhope is rescued by a mysterious individual who calls himself "Phlannel Boxingday"; almost certainly Princess Bubblegum in disguise. Phlannel's profession is hunting greed lards from his cloud ship. After nursing Lemonhope back to health he offers to take him on as his apprentice. Lemonhope agrees and seems to enjoy his life on the cloud ship, but the nightmares about his people continue. Phlannel manages to convince him that the best way to make them stop would probably be to fulfil his responsibility to the people of the earldom.
It's true you are free. Free to help the lemon people or leave them be. But a debt unpaid is not easily forgotten. So you are a prisoner still, in deinem kopf.
Phlannel Boxingday [S05E51 Lemonhope Part Two]
Lemonhope decides that he will make it his mission to defeat Fat Lemongrab, but only to make the nightmares stop rather than in duty to his people. He arrives at the earldom, and with help from the lemon citizens he is able to use his harp to cause Fat Lemongrab to explode. Both Lemongrabs are ripped apart in the blast, and the earldom is liberated from Fat Lemongrab's tyranny. [S05E51 Lemonhope Part Two]
Bubblegum sews the remains of the two Lemongrabs into one new Lemongrab, recognising that being alone is his only stable relationship model, and puts him back in charge of the earldom, hoping that he will do better this time. Lemonhope, now truly free, chooses to leave the Candy Kingdom and explore the world, declining Bubblegum's assumption that he would want to stay with his people.
I mean, you guys are cool and all, but... I mostly came back here so I could stop thinking about y'all all the time. I'll be back when I'm tired of being free. See you in a thousand years I guess.
Lemonhope [S05E51 Lemonhope Part Two]
Lemongrab begins structuring the earldom into a slightly better place, and manages to find peace with himself after defeating the mysterious collective entity known as Matthew. [S06E28 The Mountain]
Finn meets Billy's ex-girlfriend Canyon, and together they decide to complete Billy's bucket list to honour the death of the great hero. The final item on the list, however, is Finn's single greatest nightmare; he must overcome his paralysing fear of the ocean, perpetuated by the parasitic Fear Feaster which still lives inside him. Finn is determined to honour Billy, so he falls off the end of a pier. The Fear Feaster emerges to torment Finn, but Finn finds that he has drawn the Grass Sword; or rather, the Grass Sword has drawn itself. Despite the Fear Feaster claiming that no "mortal weapon" can harm him, Finn slays the parasite and suddenly finds that his fear is gone. Having completed the list, Finn experiences a vision of Billy, who tells him that his real human father, Martin Mertens, is still locked up in the Citadel. [S05E52 Billy's Bucket List]
Meanwhile, Jake has been spending more and more of his time partying in the Time Room, having made friends with the almighty Prismo. The Lich is also still trapped in the Time Room.
Those guys are doing selfies on the Lich. Is that safe?
Oh yeah, it's fine. He's harmless.
Yeah, but why isn't he killing everyone in the room right now? Controlling our minds, making us rip each other's eyes out while we buttercup one another?
Well, the Lich's primary function is to cause mass death. And since he can't do that while he's trapped in my Time Room, he's stuck in a standstill, like a machine without a purpose.
Peppermint Butler and Prismo [S06E01 Wake Up]
After Jake hears about Finn's father being trapped in the Citadel, he suggests going to Prismo for advice. Prismo tells them that the only way to get to the Citadel is to commit a cosmic crime. One such crime would be to murder a wish master such as himself. He tells them that they can temporarily "kill" him by waking up the mysterious old man who dreams of his existence.
Don't worry. As soon as my corporeal body falls back asleep again (in a thousand years) I'll be back.
Prismo [S06E01 Wake Up]
Finn and Jake retrieve the old man and bring him back to the Time Room so that Prismo can see himself one last time. However, the Lich, who has overheard their whole conversation, leaps up and disintegrates the old man, apparently ending Prismo's existence for good. The Guardians of the Citadel show up to arrest him and Finn and Jake follow the Lich through the portal to the Citadel. [S06E01 Wake Up]
Once in the Citadel, the Lich begins to melt the crystal keeping him and the other prisoners in place, and a mass breakout of all the worst criminals in the Multiverse begins. One of the escapees is Martin Mertens; Finn's father. However, rather than the happy family reunion Finn had been expecting, Martin shows no signs of even recognising Finn or caring that he's his son. His leg is blasted off by one of the Guardians and he is forced to take Finn's help. Finn retrieves some of the Guardian blood, which has healing properties, and uses it to regrow Martin's leg. But Martin still shows no gratitude and attempts to abandon Finn and escape with the other prisoners.
Meanwhile, the Lich escapes his own crystal and begins controlling the prisoners' minds to build an army. He confronts Finn.
Fall. You are alone, child. There is only darkness for you, and only death for your people. These ancients are just the beginning. I will command a great and terrible army, and we will sail to a billion worlds. We will sail until every light has been extinguished. You are strong, child. But I am beyond strength. I am the End.
The Lich [S06E02 Escape from the Citadel]
But just as he is about to strike Finn down, Finn throws some of the leftover Guardian blood into his chest cavity. Convulsing violently, a new body grows around the Lich and transforms him from a skeletal monster to a massive baby-like creature. The evil within him is washed away and he takes on the personality of an innocent child.
Finn grabs Martin's spaceship in an attempt to prevent him and the other prisoners from escaping. The Grass Sword expands and grows around his entire arm to enforce his grip. However, this is not enough. The spaceship pulls away into the void and Finn's entire arm is ripped off, leaving nothing but a stump with a small flower growing out of it. The amputated Finn escapes through a portal back to the Land of Ooo along with Jake and the babified Lich.
Finn and Jake leave the Lich on the doorstep of the recently married Tree Trunks and Mr. Pig, who decide to raise the child as their own under the name "Sweet Pig-Trunks", or Sweet P for short. [S06E02 Escape from the Citadel]
You just went through some outrageous beeswax with losing your favourite arm and etcetera. You can't expect to just bounce right back to normal. All these princesses, donating all these gross fake arms; they mean well, but they're throwing you off your game. You gotta go at your own pace. If you listen deep in your melon heart, that's where the real instructions are.
My melon wants to punch my dad in the face and steal his arm.
Well those things are bad. So they can't be the real instructions. But you keep listening.
Jake and Finn [S06E04 The Tower]
Finn begins to obsess about getting revenge on his father for causing him to lose his arm. Somehow, he manifests what Princess Bubblegum calls a "telekinetic electro-emotional prosthesis"; a magic arm. Finn uses the arm to build an enormous tower into the upper atmosphere. He meets a cloud person named Carol during his journey into the sky. Meanwhile, on the ground, Jake and Bubblegum argue about whether they should let him work things out on his own or whether they should intervene to prevent him from hurting himself. At the edge of space, Finn appears to get abducted, and wakes up in a spaceship where he finds Martin. However, after attempting to tear off his arm, Finn realises that enacting revenge isn't as cathartic as he had been expecting. At that point, Princess Bubblegum reveals that the whole thing was staged. Martin was actually merely a costume, and the "spaceship" is actually the Candy Kingdom's fallout shelter, where Bubblegum took him after he fell unconscious. The magical arm de-manifests and Finn feels slightly better about the whole situation with his father. [S06E04 The Tower]
A large portion of the Candy Kingdom is accidentally demolished when the tower collapses, losing Finn a lot of trust amongst the candy people. [S06E04 The Tower, S06E42 Hot Diggity Doom]
Finn descends into another period of depression. He tries to make out with as many princesses as possible (including Lumpy Space Princess) in an attempt to cheer his mood and save the wilting flower that grows from his stump, but none of it really helps. Eventually he meets a virgin queen bee named Breezy, who falls in love with Finn's flower and becomes a true queen to save Finn from a group of thugs. Somehow, this allows Finn to grow a brand new fully developed arm. Breezy keeps the flower. [S06E06 Breezy]
After a thousand years of loneliness, Ice King finally manages to maintain some relationships beyond kidnapping princesses. His emotional maturity improves, especially when he takes off his crown. [S05E22 The Party's Over, Isla de Señorita]
As previously discussed, his most notable friend during this time is Abracadaniel, who, despite their past rivalry during Wizard Battle, he befriends after they stay together at the Tree Fort. In addition, Ice King accidentally frees the Ancient Sleeping Magi of Life Giving from his dungeon in an attempt to get him to bring Fionna and Cake into the real world, which fails of course. ASMoLG accidentally brings Finn's hat to life with an evil spirit. The hat attacks the Candy Kingdom and manages to possess one of the Gumball Guardians, but after learning how to properly control his powers ASMoLG is able to turn him good. The hat becomes known as Little Dude, and he and his creator at some point befriend the Ice King. [S03E08 Wizard Battle, S05E40 Play Date, S05E08 Mystery Dungeon, S05E10 Little Dude]
All of this culminates in a road trip to a magical place called Big Butt Rock where they intend to form a new school of magic. Abracadaniel hires a bus and departs along with Ice King, ASMoLG, Little Dude, a Wizard City shopkeeper named Ron James, a goblin wizard named Beau, a stranger named Giuseppe, and the water nymphs who live in the pond by the Tree Fort. Giuseppe is lost after stepping off the bus to collect some crabapples, and the water nymphs bail on the trip after the bus gets stuck in a swamp. But the mysterious Giuseppe returns and uses telekinetic powers to lift the bus out of the swamp before disappearing. The road trip cements the wizards' friendship and they form their own secret society named the Order of Giuseppe, with the crabapple tree as their symbol. Probably for the first time since putting on the crown, Ice King has a real group of friends. [S06E13 Thanks for the Crabapples, Giuseppe!, Ice King #3]
Due to the nature of the crown, Ice King falls out with the other members frequently and isn't a particularly good friend to them. But through thick and thin he remains a member of the Order of Giuseppe. A wizard named Alistair Blacktide joins the Order after befriending the Ice King. [S06E32 Friends Forever, Ice King #6]
Princess Bubblegum decides to set up a fake kidnapping case to test the investigative capabilities of the Banana Guard. Finn and Jake pretend to steal her away and throw her into Lake Butterscotch wrapped in a carpet, leaving clues for the banana guards along the way. However, it is instead Root Beer Guy who ends up solving the case. As a result, Root Beer Guy is made captain of the Banana Guard and is able to quit his job at the call centre. He replaces the former captain, whose failures included letting Jake's gang get away with the Bakers' Shard. Root Beer Guy also stops writing his detective novel, since he's now living the life of a real detective, much to the relief of his long-suffering wife Cherry Cream Soda. [S05E23 One Last Job, S05E43 Root Beer Guy]
Meanwhile, Maja returns to the Candy Kingdom with dreams of conquest, having used the sentimental power of Bubblegum's shirt to raise a powerful being named Darren the Ancient Sleeper. Root Beer Guy is killed while activating a force field to keep Darren in place. His sacrifice does not go to waste; Darren is defeated by Finn and the Ancient Psychic Tandem War Elephant, who Finn and Jake had recently discovered was still living in their treasure room. Maja is put in a coma during the battle, and afterwards APTWE chooses to look after her until she wakes up. [S06E08 Furniture & Meat, S06E10 Something Big]
Maja's in a coma and she might not wake up.
I'm glad you've got a friend now even though that's messed up.
APTWE and Jake singing My Name is Jake [S07E25 Flute Spell]
Maja's abused crabbit familiar is finally freed from servitude and pursues his dreams of becoming a dancer. [S05E29 Sky Witch, S10E16 Come Along With Me Part 4]
Before Maja's attack, a new timeline is created when Princess Bubblegum decides to open the Banana Guard to non-bananas. Commandant Banana Guard, the former captain, is envious of Root Beer Guy for taking his job and plots to sabotage him by deliberately failing all of the new recruits. In response, the recruits make plans to have the Commandant fired and replaced. The original candidate for his replacement is Lemongrab, but after he is killed by Lemonhope, Bubblegum offers the job to Root Beer Guy in addition to his captaincy. However, he is also killed during Maja's attack. After Peppermint Butler consults an oracle to ask whether or not they should have Commandant Banana Guard replaced, the timeline fractures into two further alternate realities; one where the Commandant is fired, and one where he keeps his position. Peppermint Butler is able to repair the Multiverse after talking to the ghost of Root Beer Guy, but the reunified timeline inadvertently leads to a robot apocalypse for some reason. [Banana Guard Academy #1 to #5]
Five years later, in 1004 AMB, Peppermint Butler and the small group of remaining rebels journey to the Citadel of Temporal Attunement, where he is able to travel back in time and undo the apocalypse by preventing Princess Bubblegum from opening the Banana Guard to non-bananas. This erases the entire timeline, leaving Peppermint Butler as the only one able to remember it. He apparently makes no attempt to prevent the defeat of Lemongrab or the death of Root Beer Guy the second time around, preferring to let destiny run its course. [Banana Guard Academy #6]
Cherry Cream Soda, while in mourning for her lost husband, rebounds and ends up marrying the gravedigger and conspiracy theorist Starchy. However, Root Beer Guy is resurrected after his corpse is struck by lightning and becomes known as Dirt Beer Guy. He and Starchy get into a fight over which of them deserves to be with Cherry Cream Soda and she chooses to return to Dirt Beer Guy. [S07E03 Cherry Cream Soda]
I'm still dead. I'm actually talking to you from the past. I set up this plan B scenario in case I ever got croaked for real. So if this is happening I guess I got croaked and my pickles ran out. But Jake and I established a bro-bond that could bring me back through his dreams.
So are you actually talking to me right now? Or are you pretending to in an empty room?
I was pretending, but now I can see you.
Prismo and Finn [S06E19 Is That You?]
Before his death, Prismo organises a crazy "Plan B" scenario in the event that his host body is killed. The plan uses a complicated mess of interlocking timelines in order to duplicate Finn and Jake and have one of the Jakes become his new host body. The plan is set to trigger when Finn and Jake consume what is allegedly the last of his pickles. The plan is successful, and Prismo returns to life. The duplicate of Jake falls asleep in the Time Room and transforms back into the old man who was killed by the Lich. The duplicate of Finn gets transformed into a sword by some kind of paradox. The Finn Sword contains a copy of Finn's consciousness, and Finn takes it back to Earth and begins using it as his primary sword. [S06E19 Is That You?]
Although Plan B is triggered, Jake later reveals that he had actually embezzled one more jar of Prismo's pickles and keeps them hidden under his pillow. [Finn & Jake Investigations]
Despite his past recklessness, Jake begins to become more reflective and aware of his own mortality, especially given he has technically died at least twice already; once when Abraham Lincoln mistakenly executed him, and once when BMO temporarily stopped his heart so he could enter a low level Dead World and kill a ghost fly. He begins to go through some of his own existential dilemmas, just like Finn did when he travelled into Pillow World. [S04E15 Sons of Mars, S06E17 Ghost Fly, S06E18 Everything's Jake, S06E20 Jake the Brick]
I think maybe I don't like old people. They make me feel like I'm gonna get old one day too.
Jake [S07E14 The More You Moe, The Moe You Know Part 1]
Princess Bubblegum's espionage operations in the Fire Kingdom uncover the existence of the Sleeping Fire Giants, the ancient weapons built by Moe and alleged to be the progenitors of the kingdom. Fearful of what Flame Princess or her less stable brother could do with such power, Bubblegum plots to disable the weapons. She secretly has Ice King freeze the kingdom's core in order to trick Flame Princess into seeking her help to fix the problem. After infiltrating the kingdom, Bubblegum attempts to disable the giants. But she is caught red-handed by Flame Princess.
You're never going to change, are you? You'll just keep walking all over us little people. You're cold, PB. And it's not because you're a scientist or a leader. It's because you are a bad person.
Flame Princess [S06E22 The Cooler]
After a brief fight, Bubblegum begins to see how much her power has corrupted her. Most of the Fire Giants are destroyed in the battle, but Bubblegum allows Flame Princess to keep the very last one. Upon returning to the Candy Kingdom, she shuts down a large portion of her surveillance network in an attempt to amend for her actions. [S06E22 The Cooler]
I mean it's a lot of responsibility looking after so many people. Though lately I have been trying to be more chill about it.
Cool. Like, taking ice cream breaks?
Yeah, and, like, being more... sorta okay with everyone making mistakes around me. Like, mind my own stuff more. You know what I mean?
Princess Bubblegum and Finn [S06E23 The Pajama War]
Her past malevolence and the warped stories of the first candy people mean that many of her subjects continue to fear her. As part of her efforts to become a better person, she takes time to focus on the things which make each of her individual subjects special in their own way. The banana guards, who are under the presumption that any form of uniqueness will be quelled and punished, are terrified of the princess and literally worship her like a god. So in an effort to dispel this fear she contracts Banana Guard 16, who has secretly been doing graffiti on the streets of the kingdom, to paint a mural in the castle's banquet hall. The other banana guards are taught to celebrate their uniqueness rather than hide it; a kind of personal freedom that Princess Bubblegum has never before encouraged. [S07E26 The Thin Yellow Line]
Marceline is supportive of Bubblegum's new attitude, encouraging her to continue dismantling the surveillance network. [Season 11 #6]
A fast moving object enters the Solar System on a collision course with the Martian society. Despite its strange course and the fact that it is several months early, Grob Gob Glob Grod believes it to be the newest incarnation of the Catalyst Comet. After Martian missiles fail to divert the object, Glob flies into it to save Mars and put the comet back onto its correct course towards Earth, and appears to perish in the collision.
If just being born is the greatest act of creation, then what are you supposed to do after that? Isn't everything that comes next sort of a disappointment? Slowly entropying until we deflate into a pile of mush?
Well, it's not enough to have created something amazing, right? What if I just let my Martian super-society go to butt?
But what's it worth if we all gonna get blowed up right now?
Finn and Glob [S06E25 Astral Plane]
However, Glob actually survives. His four heads end up in orbit around the Earth. [S08E07 Normal Man]
In addition, the object was not actually an early Catalyst Comet but in fact a spaceship piloted by Martin Mertens. It crash lands in a village in Ooo. Finn is guided towards it during a dream, and wakes up there having sleepwalked for two days. He finds Martin tricking the local villagers into helping him repair his pod so he can return to space. Martin continues to act like a complete wad towards his son and does not leave on good terms.
What the heck, Dad! Is everything you say a lie?
No, no, of course not.
Well, is there any way I can tell the difference?
Ha hah, I hope not!
Finn and Martin [S06E27 The Visitor]
His brief visit was, however, enough for Finn to realise that he no longer has such a strong desire for revenge. But it also makes him wonder what triggered the dream which led him there, given Martin's ship wasn't actually anything mystical. [S06E27 The Visitor]
When Marceline holds a yard sale to sell off some of the late Billy's old artifacts, Wildberry Princess buys an artifact called the Feed Bucket of Plenty. This artifact regenerates the Wildberry Kingdom's livestock to improve the productivity of their lucrative meat industry. However, the regenerated meat has extreme side effects; the wildberry people who eat it become servile fruit-meat hybrids known as "food boys". Since there is no way to turn them back, Wildberry Princess donates them to the Huge King, who lives in an underground cavern and is looking for servants to keep him fed. She gives the Feed Bucket of Plenty back to Marceline, who locks it back up in Billy's cave along with all the other dangerous artifacts she sold. [Finn & Jake Investigations: Artifact Checking]
One day, a travelling sales-bear named Bill falls into the Huge King's chimney. Just as his carriage is slipping in, he manages to fashion a parachute. His makeshift parachute platform is kept aloft by the heat from the Huge King's stove top, leading Bill to believe that the hole is bottomless. He scratches his name into his platform so he doesn't forget it, but when he does forget his name he reads the writing upside down and renames himself 7718, or just Seven for short. He keeps his health by drinking rain and eating walnuts that fall into the chimney from above, and he keeps his sanity (for the most part) by playing FreeCell.
And I guess that was enough.
Seven [S06E31 Walnuts & Rain]
Months later, while walking through the forest, Finn and Jake each fall into two different holes above the Huge King's lair. Finn falls into the lair itself and is kidnapped by the Huge King. Jake falls down the chimney and ends up on Seven's platform. Finn plots to escape by befriending the food boys and attempting to destroy the king's beloved clock. During this, Finn spills water onto the stoves and puts them out, causing Seven's platform to fall into the kitchen. He, Jake, and Seven are able to escape the Huge King's lair. [S06E31 Walnuts & Rain]
Finn and Jake's brother Jermaine has been guarding their old family home ever since the death of Joshua and Margaret. The demons who want their possessions back have grown no less rowdy in all this time and are kept outside by a salt barrier. Jermaine keeps one of them, named Bryce, locked up in his basement. But the spell used to keep the demon in place must be refreshed regularly by flipping a cassette tape, meaning Jermaine is just as trapped as his captive.
After Jake reaches Jermaine via his dreams he resolves to go and visit his brother in the real world. He and Finn arrive at the old house and immediately begin messing around with the artifacts that Jermaine spends his life protecting. Jake even breaks the salt barrier to get some salt to make fried rice, letting a demon into the house. Eventually Jake and Jermaine get into a fight and accidentally start a fire. But rather than attempting to save the house, Jermaine decides he's had enough.
Let it burn.
But all of Dad's stuff!
No. I think it's alright.
Jermaine and Finn [S06E33 Jermaine]
Finally free from having to spend his days flipping a cassette tape, Jermaine becomes a painter. He initially focusses on strictly representational landscape art, but later he gets into abstractionism. He ends up forming a professional relationship with Bryce, his former captive, who becomes his art dealer. [S09E01 Orb, S09E10 Abstract]
Since Tree Trunks' wedding, the self-proclaimed King of Ooo has apparently managed to go broke. It's possible his assets were seized after he escaped prison, but it feels more likely that he just spent all his money irresponsibly. So he and Toronto begin to enact his next big plan. Part of that is to exploit Tree Trunks and Mr. Pig's newly adopted son, the former Lich now known as Sweet P.
Soon we'll have enough scratch to fund my big comeback. This kid is great at helping us rob people.
King of Ooo [S06E26 Gold Stars]
However, this exploitation uncovers Sweet P's hidden dark side and his Lich half is able to scare away the thieves. But again, this would not be the last the Candy Kingdom would see of the King of Ooo. Later on, Sweet P begins to have dreams about the approaching Purple Catalyst Comet. [S06E26 Gold Stars, S06E39 Be Sweet]
Gunter, the penguin form of Orgalorg, still harbours some deep recognition of his true identity. Masquerading as a female bird, he meets the Cosmic Owl during a dream. The Cosmic Owl falls in love with the dream version of Gunter, and Gunter is able to manipulate him into granting him access to Princess Bubblegum's dream. He interferes and causes the dream to go bad, depicting rebellion against Princess Bubblegum and the fall of the kingdom. And since the Cosmic Owl is present, the events of the dream become inevitable. Gunter does not seem entirely aware of the consequences of his actions, but the shadow of Orgalorg buried deep within him has a plan. [S06E36 Hoots]
A few days later, the penguins of the Ice Kingdom all hold a party in the Ice King's lair. While rescuing Lumpy Space Princess from a walrus, Gunter cracks his head open. This catalyses some kind of change within Gunter's mind. For a brief time, Orgalorg takes over. He constructs a ritual to inform his subjects that he has returned, but halfway through Gunter fights back into his own mind and puts a stop to it. But the damage is done, as Orgalorg begins clawing his way back towards consciousness. Like Sweet P, he begins having visions of the impending comet. [S06E40 Orgalorg]
Princess Bubblegum also foresees the Purple Comet; not through a dream or through a vision, but through a telescope. She understands the destruction it could potentially bring and decides to continue with her space program. Since her previous spacecraft was stolen by the leaflan during her mission to rescue Marceline, she designs a new one. Her plan is presumably to redirect the comet should it end up on a collision course with her kingdom. [Marceline Gone Adrift #6, S06E42 Hot Diggity Doom]
Orgalorg meets the King of Ooo at some point. The King of Ooo is planning to run an election against Princess Bubblegum to have himself voted in as the new princess. The election is apparently "barely yet fully legal" despite the fact that the Candy Kingdom has traditionally been an autocracy ruled by nobody other than Princess Bubblegum, with very few exceptions. Believing that this will help bring about the fall of the kingdom as depicted in Bubblegum's dream, Orgalorg decides to help the King of Ooo and becomes his campaign manager under the guise of "Mr. X", a mysterious cloaked individual. Together, Orgalorg, Toronto, and the Veritas Brigade (Starchy's secret society) campaign for the King of Ooo's election to the gullible and easily swayed candy people. Princess Bubblegum, believing that there is no way she would ever lose given the electorate is comprised of her own creations, does not campaign, and instead spends her time continuing to study the Purple Comet. [S06E42 Hot Diggity Doom, S08E17 High Strangeness]
I'm studying something that could be real important. This dumb election. It's not even... I mean, it's barely even legal. And even being legal; I made everyone. I made their homes. The candy people are mercurial, but they're not dillweeds. They know that I love them.
Princess Bubblegum [S06E42 Hot Diggity Doom]
However, Bubblegum is wrong. Following the election, the results are announced by Starchy, leader of the Veritas Brigade, who reveals that the winner is in fact King of Ooo. Horrified and upset with her people, Bubblegum and the ever-loyal Peppermint Butler move out of the castle and begin living at Gumbald's old shack on the shore of Lake Butterscotch. She tells Finn and Jake to remain behind and keep an eye on her former subjects, knowing that something big is coming.
Your allegiance is to the kingdom. Dudes, I don't know. I don't know when I'll be back in charge... if I'll be back in charge. I need you both to stick around here and make sure the candy people are safe, even if it means working for a wad. Auf wiedersehen, meine champions.
Bubblegum [S06E42 Hot Diggity Doom]
A mere few hours after the King of Ooo's inauguration, the sky begins to turn purple and the people of the Candy Kingdom begin to panic. With Bubblegum exiled and the kingdom's forces preoccupied, Orgalorg finishes making Bubblegum's spaceship flight-worthy and hijacks it. Just before take-off, Finn and Jake discover him in the vehicle assembly building and manage to get on board the spacecraft and don spacesuits before they leave the atmosphere. Once in orbit they encounter Orgalorg, who, finally free of the Earth's imprisoning gravity, is able to take his true form and reveal his plan. [S06E42 Hot Diggity Doom, S06E43 The Comet]
Glob K.O.-ing himself, the arrival of the Catalyst Comet, and a ship to carry me out of this planet's gravity. These are doorways the universe presented to me. It's all yours if you're willing to take it.
Orgalorg [S06E43 The Comet]
Orgalorg intends to absorb the power and knowledge of the Catalyst Comet, just as he attempted thousands of years ago when he was first defeated by Glob and banished to Earth. He perceives his stowaways as little more than a minor nuisance, and throws them out into space where Finn and Jake drift apart and lose each other. With no other options, Finn can do nothing but make what he calls an "appeal to higher forces". And yet somehow, this is enough. From nowhere, Martin appears, riding a moth which he had stolen from the koala people. Despite their history, Finn is relieved to see his father again. The moth flies them both back towards Orgalorg, who has begun to digest the comet. Seeing his opportunity, Finn leaps into Orgalorg's mouth in a last ditch effort to stop him. Finn's Grass Sword, which has been trapped inside his new arm ever since he received it, emerges and whips around inside Orgalorg's stomach, tearing him apart from the inside and freeing the Purple Catalyst Comet. It breaks open, and the consciousness of the comet converses with Finn and Martin and offers Finn a new mode of existence. [S06E40 Orgalorg, S06E41 On The Lam, S06E43 The Comet]
I give you a choice: come with me to the end and the beginning, or struggle here a while like a beautiful autumn leaf. This is your crisis.
The Purple Catalyst Comet [S06E43 The Comet]
Finn declines the offer, but Martin decides that leaving the physical plane sounds like a pretty neat deal. Martin and the Comet discorporate, leaving Finn alone and drifting in space once again. But the higher forces still have one trick up their sleeve. Jake's prophetic dream from three years prior, which he believed was a vision of his own death, comes true. Bubblegum had not been the only one planning to travel into space to see the Comet; Banana Man had also been developing his own spacecraft. Banana Man comes across Jake drifting on his own through the darkness, and after being rescued they manage to find Finn as well. The remains of Orgalorg manage to grab onto the spacecraft as it is de-orbiting, and he becomes compressed during re-entry back into his usual harmless penguin form. Finn, Jake, Banana Man, and Gunter all splash down in Butterscotch Lake, and the Land of Ooo is safe once more. [S06E43 The Comet]
While the King of Ooo's failure to deal with the comet and the kingdom's other problems lose him some trust amongst his new subjects, he remains in power for now. [S07E01 Bonnie and Neddy]
Bubblegum and Peppermint Butler are leading a simple life away from the Candy Kingdom, keeping themselves busy by repairing Gumbald's dilapidated shack. However, Bubblegum finds herself having to intervene in royal affairs after Finn, Jake, Toronto, and the King of Ooo discover her dragon brother Neddy under the Great Tree during a treasure census. Neddy, terrified by the unexpected strangers who have invaded his space, runs away from the kingdom. The juice produced by Neddy is the lifeblood of the kingdom, powering its plumbing and electricity generation, and acting as a defensive moat. After its production ceases, the King of Ooo recognises that the kingdom's collapse is imminent and plans to charge a high price for the remainder of the juice so that he can still make a profit out of the deteriorating situation. Finn and Jake, meanwhile, go to Bubblegum for help. She is able to track down her brother and returns him to his chamber under the tree where he is able to continue producing the juice. She gives the banana guards outside his chamber secret permission to prevent the King of Ooo from ever entering again, and the kingdom is safe once more.
Hey Bonnie... You always act like a loner, right? But next to your brother you're the light of the party.
I mean yeah. One of the first things I did after making sure Neddy was safe was to start making the candy people. I was formed in the Mother Gum. My mind and my gum were in touch with dozens of others, like a crowded womb. I guess I missed that... People get built different. We don't need to figure it out, we just need to respect it. Maybe Neddy likes his own company better than I like mine.
Well, do you miss the candy people?
Finn and Bubblegum [S07E01 Bonnie and Neddy]
Finn and Jake continue working for the King of Ooo for a while longer, but they are fired from the royal guard after they fail to procure a flying mushroom for him. [S07E04 Mama Said]
Marceline doesn't learn about the election until Bubblegum has already been off the throne for two months. The fact that Bubblegum no longer has a kingdom to worry about gives them a unique opportunity to reconnect. Although their friendship has been slowly repairing for the past few years, this is the first time Bubblegum truly opens up to Marceline about the problems she is facing.
I lost my hat, lost my home, lost my people. I can't even keep darn varmints out of my pumpkin patch. I tried. I really really tried. I just - I thought that if I shut everything out and just focused on work it would all be okay. And look where that landed me. All I managed to do is push everyone away. I pushed you away. I'm sorry Marceline. I've been a real dinger to you.
Bubblegum [S07E02 Varmints]
Conversely, Marceline also begins to have some much deeper discussions with Bubblegum about her own concerns; most notably, she is unsure if she wants to remain immortal. Bubblegum begins researching methods to "cure" Marceline's vampirism. [S07E06 Marceline the Vampire Queen]
You said you were working on a cure, right?
Well... The machine is built and the serums are ready, but... are you sure you wanna do this?
I'm sure. Some bad things happened to me when I was little. When I became a vampire, I was just a messed up kid. Now it's a thousand years later and I'm still messed up. I don't wanna spend eternity like this. With this emptiness. I wanna grow up.
This means someday you'll die. You know that, right?
I guess that'll be my last adventure.
Marceline and Bubblegum [S07E06 Marceline the Vampire Queen]
Marceline, who by this point is over a thousand years old, decides that she has had enough of her immortality. From the new lab which Bubblegum has constructed under Gumbald's shack, she is able to extract Marceline's vampire effluvium, effectively curing her vampirism and making her mortal. This also strips her of the various powers she has absorbed, and Marceline discovers she has arthritis in her legs due to flying everywhere. But Bubblegum is unsure whether or not the procedure has really worked, so she tells Marceline to get some sleep and wait until morning. That night, a local village's livestock are mysteriously attacked and drained of their blood. Being the only vampire in Ooo, Marceline is the prime suspect of the attack, and the villagers form a mob. They abduct Marceline, tie her to the top of their windmill, and wait for the sun to rise. Meanwhile, Finn and Jake track down the actual attacker to a cave and discover that it is not Marceline. But by the time Finn discovers the villager's execution plans, the sun is already rising. [S07E06 Marceline the Vampire Queen]
Luckily, Bubblegum's cure has indeed worked. The sun can no longer harm Marceline. Jake, who wakes up in the cave after fainting, discovers the true culprits; a group of vampires manifested from Marceline's extracted effluvium. When he returns to the others, Marceline realises that the vampires are all the members of the ancient Vampire Court whose souls she absorbed; The Fool, The Empress, The Moon, The Heirophant, and The King. Peppermint Butler has been stockpiling anti-vampire weaponry in case Marceline ever decided to turn against his mistress. Together, Peppermint Butler, Bubblegum, Marceline, Finn, and Jake set out to track down all the vampires before they can return to full power and take over the whole of Ooo. [S07E07 Everything Stays, S07E08 Vamps About]
It doesn't take Marceline long to discover The King and The Fool hiding out in the woods. Although The King claims to have changed his ways, Marceline doesn't believe him.
Things are different now. The humans are long gone.
Someone's smelling a bit human herself these days. Anyway, you don't need to worry. I've changed as well. I only eat animals now, just like everyone else. Does that mean we can be friends now, Marceline?
It doesn't matter how you pretend to change. You've done enough already to get staked a thousand times over.
Marceline and The Vampire King [S07E08 Vamps About]
Marceline stakes The Fool and re-absorbs his soul and the power of flight. But she abandons her fight against The King after he tells her that The Empress is on her way to the Ice Kingdom. Fearing for Ice King, Marceline flies there immediately to try to take her down on her own. The Empress almost gets the better of Marceline, but Bubblegum comes to the rescue. Marceline stakes The Empress, sucks her soul, and regains the power of invisibility. After this, Marceline promises to stay with the others. [S07E08 Vamps About, S07E09 The Empress Eyes]
Next on their list is The Moon, but before that they are intercepted by The Heirophant. He offers to team up with Marceline, but disagrees with her requirement that he must switch to drinking the colour red rather than actual blood. He proves a formidable adversary and poisons Marceline with scorpion venom. However, his weakness is the fact that he plays by "old timey rules" and cannot cross the threshold of a home without permission. Jake shape-shifts into a house and The Heirophant is pushed inside by Crunchy. Having violated the rule, he dies, and his soul is absorbed by Marceline. She regains her shape-shifting powers but is rapidly succumbing to the poison. [S07E10 May I Come In?]
Bubblegum sends Finn and Jake to capture The Moon while she and Peppermint Butler take Marceline back to Peppermint Butler's secret poison lab in the Candy Kingdom. The King of Ooo tries to stop them, but the banana guards still don't really recognise his authority over Bubblegum.
Monarchies... are not... DEMOCRACIES!
Princess Bubblegum [S07E11 Take Her Back]
Peppermint Butler's methods for healing the poison are either very slow or completely ineffective. Thankfully, Finn and Jake show up with The Moon. Peppermint Butler stakes her, and Marceline is able to quickly absorb her soul before she can heal the wound. With her healing powers restored, Marceline recovers from the poison. In a repetition of events from nearly a thousand years prior, this leaves The Vampire King as the last of his kind. [S07E11 Take Her Back]
But the Vampire King does not want things to repeat.
How many times do you wanna do this, Marceline? Our lives have magnetised. We're in a negative loop. But we can change our outcome this time.
I like the outcome where you get staked.
And you become a vampire? Marceline. I know I was ruthless in the past. But tell me, what's the one thing you've noticed about the world, since you beat me all those hundreds of years ago?
Everything repeats over and over again. No one learns anything, 'cause no one lives long enough to see the pattern, I guess.
But you've lived long enough. And you still think this is the right way? Fighting me?
The other way's like a black hole; an unknown.
I'm not afraid of the unknown! I have the power to change destiny! Queen of vampires! You weigh the scales of fate. Spill my guts, or face the unknown. Either way, I will not bite. For turning you would subjugate me to the wheel of fortune. And I am a king. Not a hamster.
The Vampire King and Marceline [S07E12 Checkmate]
They come to a truce. The Vampire King decides that he no longer wishes to be a vampire, and asks Bubblegum to cure him as she did for Marceline. The procedure is successful a second time, and The King reverts to his mortal self; an ordinary lion. However, his vampire effluvium is even more potent than Marceline's. After Jake accidentally releases it, it manifests in the form of a gigantic cloud creature known as the Dark Cloud, and begins rampaging towards the Candy Kingdom. The accompanying explosion destroys Gumbald's cabin. [S07E12 Checkmate]
The candy people spot the impending monster. Seeing Bubblegum battle against it, and how apathetic the King of Ooo is in comparison to her, a revolution begins. Crunchy throws the King of Ooo into his fireplace, where he melts into a puddle of wax. Temporarily taking the role of princess, Crunchy orders the kingdom's infantry to help in the fight against the monster. And it is not only the banana guards who join the battle; many of the kingdom's other citizens also take up arms. Proud of her people, Bubblegum continues to battle along with Finn and Jake. The Fire Kingdom and Hot Dog Kingdom also assist their ally. But their attempts to take down the Dark Cloud are largely ineffectual. Luckily, after some words of encouragement from Ice King, Marceline gets over her own regret and decides to finish the monster once and for all. She is able to re-absorb its vampire essence and defeat it, but gets turned back into a vampire in the process. [S07E13 The Dark Cloud]
Following the revolution, Princess Bubblegum takes back her title and her throne. She offers Marceline the opportunity to move in with her, but Marceline declines, saying she needs a little time to herself. Nevertheless, she is glad to be immortal again, and glad that Bubblegum will be with her all the way.
Nah, I'm cool being a vampire again. Being mortal was good, but at the same time it was terrifying. Now I'm a vampire with fresh mortal memories and... I dunno... more empathy or something? More grown up. Bonnie; thank you for helping me grow up. Now I guess we get to hang out together forever.
Marceline [S07E13 The Dark Cloud]
The power of the Vampire King and the Dark Cloud remain within Marceline. But overall, the status quo remains. Toronto escapes the revolution against the King of Ooo with enough stolen loot to stay afloat. [S07E13 The Dark Cloud]
Betty has spent her time in Ooo devising a theory of magic which she calls MMS; a theory which states that all magic users harbour varying degrees of magic, madness, and sadness. She hopes to one day be able to apply her studies to saving Simon from the crown's curse. At some point during her exploration of Ooo and its wizarding community, she meets Magic Man, and they agree on a plan which, if successful, would be mutually beneficial to both of them.
So this thing's really gonna transmute you into the new Glob?
Of course! And then I'm gonna make it rain on Mars in a bad way. Fire up those ovens, honey! This is exciting!
A little sad though, right?
Your brother blowing up in space. Doesn't that mess you up?
Nothing messes me up.
I don't believe that. Like; who is Margles and why is there a picture of her on your shelf? Something there connects to who you are, and your magic.
Someone shines a light into my dark wizard matter. A way to un-close the circuit of magic, madness, and sadness?
That's right! MMS runs through all magic users. Studying these symptoms could lead me to their underlying cause, and then I'll control the forces that hold sway over Simon.
Betty and Magic Man [S06E38 You Forgot Your Floaties]
Finn and Jake spot Betty scavenging Glob's helmet after it crashes to Earth following his encounter with Martin's spaceship. Betty needs it to catalyse the reaction which will grant her a deeper understanding of magic and allow Magic Man to return to Mars. Finn and Jake follow her to Magic Man's house, but Magic Man sees them approaching and turns them into a fried egg and a bowl of soup, respectively. Betty and Magic Man begin the reaction, which involves locking themselves in a trance state. While the reaction is taking place, Finn, as an egg, manages to get himself baked into a bread body in Magic Man's oven. Bread Finn destroys the apparatus and puts a premature stop to the reaction. The result of all this is that Magic Man's MMS is transferred to Betty, granting her magical powers in exchange for his own. Magic Man's side of the deal is unfulfilled. Since his name no longer applies, he renames himself "Normal Man".
What do normies do? Get smoothies or something?
Normal Man [S06E38 You Forgot Your Floaties]
Bread Finn convinces Tiny Manticore to fly him and Jake (who is still a puddle of soup) to Wizard City to get their bodies restored. Betty, now quite insane, travels back out into the world and uses her new powers and perspective to begin developing new plans for how to save Simon. [S06E38 You Forgot Your Floaties]
One of her ideas is to attempt to reprogram Evergreen's crown. To do this, she kidnaps Gunter and holds him ransom until Ice King hands over the crown, then returns Gunter and the reprogrammed crown to him after she's finished. [S07E21 King's Ransom]
This is the best date I've been on since my last date.
This is not a date.
Neither was the last one. It was a robbery. She stole my heart. And my crown.
Ice King and Princess Bubblegum [S08E01 Broke His Crown]
When Marceline and Bubblegum visit the Ice King in an attempt by Marceline to put their shaky past behind them, they discover that he is having frequent spasms and spouting nonsensical words. She and Marceline use scientific equipment to enter the circuitry of the crown to try to track down the source of the problem. While inside the crown, they meet the preserved consciousnesses of the various souls previously lost to the crown: Evergreen's assistant Gunther the dinosaur, the original Santa Claus, Sveinn the Icelandic boy, and of course, Simon Petrikov. Together they find a virus implanted into the circuitry by Betty, which is unsuccessfully attempting to undo the crown's wish magic without killing Ice King in the process. The virus is magical in nature, and as a result is a reflection of Betty herself. It recognises and falls in love with Simon's consciousness, giving up its pointless mission. The crown, now no longer under attack, re-establishes its defences and kicks out Marceline and Bubblegum. Ice King is returned to normal and Betty's plan has failed. [S08E01 Broke His Crown]
Meanwhile, Normal Man, now free from his madness and sadness, is beginning to attempt to amend for his actions. With the help of Finn, Jake, and Tiny Manticore, he retrieves Glob from space and plans to travel back to Mars with him. However, Glob decides that his brother is ready to rule on his own. Normal Man arrives on Mars alone and establishes himself as their new leader as a changed man, for the most part. [S08E07 Normal Man]
BMO introduces Finn and Jake to his ability to physically transport them into his "main brain game frame" to play video games. The antagonists of the video game Guardians of Sunshine are accidentally released into the real world, but Finn is able to defeat them. [S02E16 Guardians of Sunshine]
Like with many of their responsibilities, Finn and Jake are arguably somewhat neglectful towards BMO for a long time. This leads to BMO having a highly developed network of imaginary relationships, mostly with animals and inanimate objects around the Tree Fort. He personifies his own reflection as an imaginary friend named Football. After getting kidnapped by a giant bird, BMO befriends a bubble (simply named Bubble) on his way back to the Tree Fort. After Bubble is popped by Jake, he becomes an invisible voice in BMO's head named Air who may or may not also be imaginary. [S04E17 BMO Noire, S04E02 Five Short Graybles, S05E17 BMO Lost, S07E05 Football]
BMO journeys back to the MO Factory where he was created after accidentally deleting his own core system drivers. There, he meets his creator, Moe, who is still alive and being looked after by his creations. Underneath the factory, an entire society of MOs has developed. However, BMO chooses to keep living with Finn and Jake rather than returning to his own people, but remains in contact with them. [S05E28 Be More, Adventure Time Comics #9: "The LAN Party"]
Back when Moe first began creating robots, his first creation was AMO. As mentioned long ago, something went wrong in AMO's heart, leaving him with a destructive need for love. AMO returns to the factory in 1000 AMB after a long pilgrimage, only to find that his creator is dying. Moe passes away and gives AMO his memory backup, telling him to send it into space so he can rest in peace among the stars. However, AMO does not follow his creator's wish. He sees the love and compassion in the society of MOs who inhabit the factory and, in a jealous rage, uses knowledge from Moe's memories to hack them all and instruct them to do somersaults into the trash compactor. They are crushed into one amalgamated entity called ALLMO. After AMO learns about the happy loving life that BMO lives with Finn and Jake, he comes up with a devious plan to take his place. At BMO's "birthday party", AMO dresses up as Moe and pretends to be Moe's consciousness uploaded into a robot. He tells BMO that he must journey to the factory on a solo mission so that he can "learn how to be grown up". Finn and Jake are hesitant since they think it sounds too dangerous for BMO to handle on his own. But eventually they agree to let him go. AMO, under the guise of Moe, stays at the Tree Fort to act as a substitute for BMO while he is away. The mission obviously turns out to be fake. When BMO arrives at the factory he finds nothing but a trap designed to destroy him. He avoids the trap and rescues ALLMO and together they head back to the Tree Fort. BMO fights AMO and pushes him off a cliff to his death.
That was the craziest thing that ever happened. But I guess after all that I do feel a bit more grown. Except that the mission was just a made up lie. So who knows if I will ever grow up at all? And Moe is gone now, so if there is anything he wanted to teach me, better be in me already. I guess all I can do is listen to the heart Moe gave me. Except that's what AMO did and he turned out bad. So what if I turn out bad too? But I'm different! It's not just Moe up here. It's me too. And if I cannot trust in Moe, I can trust in me!
BMO [S07E15 The More You Moe, The Moe You Know Part 2]
BMO seems to gain a bit of a taste for adventure following this. While roleplaying as a cowboy he accidentally gets into an actual shoot-out with Me-Mow, Jake's old enemy. He, Jake, and Finn manage to arrest Me-Mow and have him locked up in the Candy Kingdom. [S07E17 Angel Face]
In addition to this, BMO finds an unexpected friend in the Ice King. Having both been deprived of real relationships, they are a good fit. [Adventure Time #27, S07E18 President Porpoise is Missing!, S10E02 Always BMO Closing]
With the help of Banana Man, BMO eventually fulfils his creator's dying wish by sending his memory drive into space on board a rocket. [S10E16 Come Along With Me Part 4]
Although Jake's wish in the Time Room appeared to erase the Farmworld timeline, it actually still persists as its own dimension. Following the detonation of the Mushroom Bomb, Farmworld Finn has been driven mad by Evergreen's crown, becoming "Ice Finn". The version of the Lich who still lives there intends to escape Farmworld by opening a portal to the Multiverse using Farmworld's copy of the Enchiridion. Prismo hires Finn and Jake from the prime Earth Dimension to travel to Farmworld and "take care" of Ice Finn so that he can't help the Lich open the portal, and gives them a weapon called "The Maid" with which to do so. However, they can't bring themselves to kill Ice Finn.
Prismo said "take care" of him.
Yeah, that means make him feel better.
Are you being stupid on purpose?
Yeah, but dude... That is me. There's gotta be something else we can do.
Jake and Finn [S07E23 Crossover]
Instead, they battle the Lich directly and defeat him using the same weapon that was meant for Ice Finn. The Lich is destroyed, but not before his hand falls into the portal and duplicates across every dimension in the Multiverse, including the prime Earth Dimension. [S07E23 Crossover]
Prismo edits Evergreen's Crown so that it is destroyed by the earlier explosion of the Mushroom Bomb, curing Ice Finn's madness. Farmworld Finn goes on to live happily with his family, and Farmworld is safe. Finn and Jake from the main timeline return to their version of Earth. Finn also embezzles the version of the Enchiridion from Farmworld since their native copy was destroyed, thinking it might come in useful. [S07E23 Crossover, S09E04 Winter Light]
Huntress Wizard is an inhabitant of Wizard City who lost contact with the Spirit of the Forest after taking up the life of a city dweller. After returning to the forest, she begins attempting to re-establish contact with him to no avail. [S07E25 Flute Spell]
Following the failures of his previous romantic endeavours, Finn isn't sure whether or not he should rush into another relationship. So when he meets Huntress Wizard and starts helping her track down the Spirit of the Forest, he keeps it quiet and suppresses the idea that he is helping her out of anything other than simple heroism. However, when Jake finds out about the situation and pushes them to open up to each other, they discover that they are actually in love with each other. But Huntress Wizard doesn't believe they are suitable for one another, as she believes they will be restricted by their love for one another even as it fades over time.
If I ever find what I'm looking for I'll become soft and I'll cease to matter in this world. Fear of softness is what drove me to the mad and sad world of wizarding. And Finn... my flute spell was for you too. You're an exceptional beast and you have great hair. But exceptional beasts like us cannot fall in love. That is the secret of ordinary people.
Huntress Wizard [S07E25 Flute Spell]
In the process of finding the Spirit of the Forest, Finn drinks from an enchanted spring which grants him immunity to electrocution. [S07E25 Flute Spell]
Despite claiming that they are incompatible, Huntress Wizard appears to retain an interest in Finn. [S08E16 Wheels]
Cinnamon Bun, who has been living in the Fire Kingdom as Flame Princess' champion, visits his home kingdom on a diplomatic mission. In a gesture of goodwill towards the Fire Kingdom, Princess Bubblegum decides to create a new candy person for Cinnamon Bun to keep him company and be his squire. The result is a small girl named Bun Bun. Finn travels to the Fire Kingdom to deliver Cinnamon Bun's new squire, and ends up staying to catch up with Flame Princess. Their conversation takes a serious tone, and they begin to open up to one another and ultimately decide that they are still friends.
When we broke up, I said sorry, but... I didn't fully understand what I did wrong. I get it now. I shouldn't have manipulated you. That was a really really messed up thing to do, and I'm truly sorry.
You've grown up a lot, man. I forgive you.
Finn and Flame Princess [S08E06 Bun Bun]
Flame Princess also reveals that she has taken up rapping as a hobby. At some point she meets Neptr and they form a rap duo. [S08E10 The Music Hole]
Meanwhile, to Cinnamon Bun's horror, Bun Bun releases the old Flame King from his lantern prison. But instead of retaking his place on the throne, Bun Bun manages to convince Flame King that it's not worth it. Flame King and Bun Bun end up living in a nearby cave where he rules over a group of chipmunks and makes no further attempts to dethrone his daughter. Cinnamon Bun returns to his place at Flame Princess' side. [S08E06 Bun Bun]
FP and I are just friends. And I'm really proud of that friendship. Getting there took a lot of trust-building and emotional growth.
Finn [S09E06 Happy Warrior]
Flame Princess' relationship with her father never improves, but she learns to come to terms with the fact that he's just a jerk. Toronto attempts to scam the Fire Kingdom from her by having her lose a rap battle against teen prodigy Son of Rap Bear, but she is able to channel her feelings about her father into a verse which wins the battle. [S10E03 Son of Rap Bear]
At this point, Finn is still using the Finn Sword; the weapon created in the Time Room from his alternate self during the resurrection of Prismo. The sword has a voice and consciousness of its own but tends to stay quiet. One day, Finn loses the sword and it is stolen by an outlaw named Bandit Princess. In the ensuing duel between Finn and Bandit Princess, the Grass Sword re-emerges from Finn's arm to assist in the fight. But to Finn's horror, the Grass Sword either accidentally or deliberately impales the gem of the Finn Sword. He retrieves the sword, but the gem is irreparably damaged and the consciousness within it appears to be dead. He begins using the Root Sword again as a temporary replacement. [S08E05 I Am a Sword, S08E07 Normal Man]
Within the gem of the Finn Sword, the alternate version of Finn is joined by some kind of grass demon who begins to take over the inside of the sword for himself, and wishes to escape.
Who are you?
Oh, you know. A curse. An Emissary from Beyond. Some kind of grass octopus spider... Don't worry about me... I want outta here though. I've pretty much done all I can do in here. You and me; we could do a lot better out there.
Sword-Finn and the grass demon [S08E14 Two Swords]
Along with this, Finn has been going through other difficult feelings. He worries that he is uncaring and narrow sighted like his father after a pair of cursed eyes cause him to temporarily kill Neptr, and he is somewhat traumatised after spending months, if not years, trapped in his own mind in the Hall of Egress. Guilty about the loss of his sword, he falls into another period of depression. Princess Bubblegum holds a battle of the bands to try to cheer him up and he meets the Music Hole. The Finn Sword appears to respond to this encounter, and Finn feels a little better. [S08E02 Don't Look, S07E24 The Hall of Egress, S08E10 The Music Hole]
Some time later, Finn and Jake go with Susan Strong to investigate some ancient parts of Beautopia which are uncovered during a low tide. While they are exploring, Doctor Gross' mobile lab burrows up from under the ground. They meet Tiffany, who Finn thought had died in the maw of a giant worm during their joint military service at Dentist. He in fact survived, and has been taken on as Doctor Gross' apprentice. They also meet Doctor Gross herself. Since escaping the Islands, she has continued to experiment on animals and develop new hybrids. She tries to perform modifications of Finn, Jake, and Susan without their consent, but they escape and destroy the mobile lab in the process. Doctor Gross is likely killed in the explosion, but Tiffany survives yet another near death experience. [S08E12 Preboot, S06E21 Dentist, S10E16 Come Along With Me Part 4]
Note: According to Ted Anderson's AMA on Discord, the final arc of Season 11 intended to reveal that Doctor Gross survived. But since the series was cancelled, I am not going to consider that to be the case.
However, Susan's implanted chip is rebooted during the encounter. Her own mind is overtaken by the chip, which resumes its previously failed mission to retrieve Finn and his father and bring them back to the Islands. Finn, Jake, and Princess Bubblegum battle Susan until Finn is eventually able to destroy her chip and return her to normal. But during the battle, the Grass Sword emerges again. It knocks out Susan and then detaches from Finn, taking his whole arm with it once again. The grass entity encounters the Finn Sword and they merge together into a new being: a grass clone of Finn. [S08E13 Reboot]
So, as you know, after Susan had gone crazy and kicked Jake's butt, my grass arm got steamed and kicked her butt, then it ran off and merged butts with my Finn Sword, and turned into this guy.
Finn [S08E14 Two Swords]
Understandably, the grass clone has an identity crisis. He has within him two voices; the voice of Sword-Finn, who initially doesn't realise he's not the real Finn, and the malevolent voice of the Emissary from Beyond. Finn and Jake decide to let him stay at the Tree Fort. Princess Bubblegum gives Finn a new bionic arm which she has been working on ever since he lost it the first time, to replace the one taken by the grass clone. Feeling guilty for Susan's hospitalisation, Finn decides to stay in the hospital and try to be a doctor for a while, although this doesn't go well. He finds a new sword at some point; a sabre-like blade named the "Small Sword". Meanwhile, Jake and the grass clone head to Grassy Wizard's dominion to try to find out why he created the Grass Sword in the first place. The grass clone is less than thrilled to learn that his existence is entirely meaningless; Grassy Wizard created the sword because he "thought it would be cool". The grass clone realises that in order to be fulfilled he needs to become his own person, so he comes up with a new name for himself and rides out into the world. [S08E14 Two Swords, S08E15 Do No Harm]
I'm not you. It's clear that I'm someone else. So from now on, call me... Fern the Human.
Fern [S08E15 Do No Harm]
The Veritas Brigade, the "secret" society who had some involvement in the election of the King of Ooo, was originally established by Starchy, the candy person gravedigger who hosts the radio call-in show The Graveyard Shift. They begin as a group who attempt to uncover conspiracies and supernatural happenings within the Candy Kingdom. One of their members is Peace Master, a magician who detects significant dark magic within the Candy Kingdom and believes it to be the work of Princess Bubblegum, threatening her via the surveillance camera which she is using to watch their meeting. However, the actual culprit is Peppermint Butler. He and Peace Master eventually confront one another in the Wizard Battle Arena, and Peppermint Butler wins him over by threatening to turn his children into evil monsters. [S06E15 Nemesis]
It is following this and the brief lizard takeover of the Candy Kingdom that the Veritas Brigade becomes a much more political group who oppose Princess Bubblegum's autocratic rule and accuse her of being a fascist. As previously mentioned, they support the King of Ooo's campaign during the democratisation of the Candy Kingdom. It is Starchy who announces the outcome of the election, perhaps hinting at some form of vote rigging. [S05E39 We Fixed a Truck, S08E17 High Strangeness, S06E42 Hot Diggity Doom]
After Tree Trunks voices her concerns about Princess Bubblegum's ever-expanding space program, she is approached by Starchy and asked to join the Veritas Brigade. One of Bubblegum's space probes impacts with the spaceship belonging to Tree Trunks' polyamorous alien consorts and hybrid children. Tree Trunks, who is already on bad terms with Princess Bubblegum due to the outcome of her wedding, believes it to be a deliberate attack on her extraterrestrial family. Bubblegum's actual intention is to seed new candy life on uninhabited worlds. The Veritas Brigade attempts to raid a vehicle assembly building on the outskirts of the Candy Kingdom in order to shut down the program, but they are caught by Bubblegum. However, Tree Trunks abducts Bubblegum into the spaceship to show her the damage she is causing first hand. They come to a mutual agreement, and Tree Trunks' alien husband agrees to take the candy probes back to his own abandoned home planet where they will be able to thrive and grow.
You and I will never be friends. But we can respect each other as mothers, and as fellow believers in the infinite promise of the cosmos above.
Tree Trunks [S08E17 High Strangeness]
Mr. Pig is less than thrilled after learning about Tree Trunks' otherworldly consorts. Their marriage is already strenuous and would have ended if Sweet P hadn't been left on their doorstep. But despite this, and a couple of other run-ins with Tree Trunks' various ex-husbands, they remain together. Tree Trunks begins writing a novel at some point. She and Mr. Pig both attend Sweet P's graduation. [S08E17 High Strangeness, S06E02 Escape from the Citadel, S10E06 Ring of Fire, S10E02 Always BMO Closing, S10E16 Come Along With Me Part 4]
Starchy ends up escaping the surveillance of Princess Bubblegum by faking his own death. He removes his tracking implant and transplants it into a grass lard, which falls into a dormant state. It is unknown what becomes of Starchy after that. Princess Bubblegum probably clones a new one per standard procedure. [S06E35 Graybles 1000+]
Following the activation of Susan's chip, an autonomous transport craft is dispatched from the human Islands to pick her up. The defences of the Candy Kingdom are overwhelmed by the craft's superior technology while it searches for Susan. It finds Finn and asks him to assist with the search. But before Finn can get any more information from it, it is destroyed by Jake. Princess Bubblegum deduces that the craft is human technology, and BMO interfaces with the ship's computer and discovers its origin; Founders' Island. [S08E20 The Invitation]
Finn, Jake, and Susan quickly organise an expedition to this previously unknown island. They borrow the Sugar Spit, a boat belonging to Princess Bubblegum which Jake had previously borrowed to travel to the Card Wars Doubles Classic. Finn entrusts Fern, who has taken up residence on the roof of the Tree Fort, to look after the Land of Ooo while he's away. BMO, once again displaying his newly discovered taste for adventure, stows away on board the ship. While Finn claims that he's only going because he thinks it would be "cool" to meet some other humans, Princess Bubblegum worries that it might be something more. [S08E20 The Invitation, S08E11 Daddy-Daughter Card Wars]
Finn; I can the sense that this trip's more important to you than you're letting on. I mean, if you make it to that island, you might find out some pretty heavy stuff. About the humans, and where you came from; about yourself. All's I'm saying is you have to promise me - promise me - that you'll come home safe.
Princess Bubblegum [S08E20 The Invitation]
The Sugar Spit sets sail and heads south west. They encounter several obstacles along the way, including a water dragon named Whipple who destroys their boat after BMO tells him he's annoying, and mind altering jellyfish who try to trick Jake into navigating into a poison reef by giving him hallucinations of his dead parents. Jake uses his shape-shifting powers to take on the role of the boat after the Sugar Spit is destroyed. Whipple forgives them for finding him annoying, and blows them a tailwind which quickly flies them all the way to the border of the islands. However, they are intercepted by the Guardian, who capsizes the boat and separates its crew. [S08E21 Whipple the Happy Dragon]
Finn and Jake wash up separately on Back-to-Nature Island. Finn encounters the malfunctioning weather system and some of the strange wildlife which wiped out the attempted human colony back in the day. He also finds Alva, the first human encounter of their journey, although she only speaks Swedish so he isn't able to find anything out from her. After being reunited with Jake, Alva draws them a map of the four islands and they depart on the back of a giant parrot to try to find Susan and BMO. [S08E22 Mysterious Island]
The next island they arrive on is the home of Better Reality, the VR game which many humans have been playing for their whole lives. They find BMO, and discover that he has become a high ranking moderator within the game's community. And when Finn and Jake arrive to take him away, he doesn't want to leave.
I do want to go with you, but I am a beautiful big man here. All of my instincts are in sync with this computer world. I'm really comfortable here.
Yeah, but it's all fake.
What's real? Your eyeballs think the sky is blue, but that's just sun rays farting a path through the barf of our atmosphere. The sky is black.
BMO and Finn [S08E23 Imaginary Resources]
Jake attempts to get BMO to come with them by destroying the game's hardware and servers, but this only upsets him. It also forces the humans to emerge into the real world, where they struggle to move due to their decrepit and atrophied bodies. Finn and Jake realise that keeping Better Reality running is the best course of action, and with BMO's help they repair the hardware and allow the humans to return to their perfect virtual worlds. Seeing how much his friends care about him, BMO voluntarily leaves the game and comes with them to the next island. [S08E23 Imaginary Resources]
They travel by tube to the ruins of Hub Island, which was abandoned following Doctor Gross' epidemic. On its shores they find Susan. The familiar surroundings trigger a sudden reflux of her memories, and she regains the ability to speak properly. She also remembers her real name: Kara. They commandeer an old transport craft and Kara plots a course to Founders' Island so that Finn can meet his people. And also his mother, Minerva Campbell, who Kara knew back when she was a seeker. [S08E24 Hide and Seek, S08E25 Min and Marty]
When the crew arrives on Founders' Island, they finally discover where most of the humans have been for the past thousand years. Founders' Island has become a seemingly utopian society, although its people are still trapped by the seekers and the Guardian. It doesn't take long for Finn to find his mother; or at least, someone who looks and sounds like his mother. She actually turns out to be one of the hundreds of Minerva-bots who look after the people of the island. They are all controlled from a central server hub where Minerva's uploaded brain map acts as the island's benevolent AI overlord. This AI is the closest thing to Finn's mother that still exists.
Is this... really you? Once you uploaded your brain and stuff? Like... are you still the same person?
I don't know for sure. But I feel like it's me. I hope that's enough.
Finn and Minerva [S08E27 The Light Cloud]
Minerva is thrilled to finally have Finn safely back on the island, but wishes to keep him there against his will for his own safety. Meanwhile, Kara happens to run into Frieda, who is still working in a toy store. To Kara's dismay, re-education has eliminated Frieda's desire to escape the Islands. Finn heads onto the streets to begin convincing other citizens that they should leave, and his words rekindle Frieda's will for freedom. Minerva is surprised to see how quickly her son is able to sway the other citizens, and takes drastic action by threatening to upload the entire population into the virtual world. But she changes her mind after realising that if the outside world made Finn the person he is, then it can't all be bad. [S08E26 The Light Cloud]
Most of the humans choose to remain on Founders' Island for a while longer. But for the first time since Two Bread Tom constructed the first Guardian nearly a thousand years prior, the option to leave is open to them.
Guardian; you have done just a terrific job. But it's time to stand down.
Minerva [S08E27 The Light Cloud]
Finn, Jake, and BMO get on a boat back towards mainland Ooo; the same ship that Marceline and the Founders repaired before first setting out on their journey across the ocean. Kara decides that she prefers the name Susan, and she and Frieda set out with their own transport to explore new places. They cross paths with Lemonhope at least once. [S08E27 The Light Cloud, S07E07 Everything Stays, S10E16 Come Along With Me Part 4]
And slowly, over the next few years, humanity will begin to spread itself back out to inhabit the world it left behind. [Season 11 #5]
Before their departure to the Islands, Finn and Jake investigate the theft of wire hangers throughout the Candy Kingdom and discover that the perpetrator is Ice King, who is making a chain out of them to retrieve some keys he dropped down a deep crack in his castle. However, when Finn, Jake, and Ice King drill into the crack to find the keys, they discover something far more interesting; the frozen form of Patience St Pim, the Ice Elemental who froze herself a thousand years prior to escape the Mushroom War. After being thawed, she allies herself with Ice King and tells him to round up the other Elementals: Flame Princess, Princess Bubblegum, and Slime Princess. But the other three are not even aware of the fact that they are Elementals, and they do not react kindly to being kidnapped and "reunited" with somebody they've never met.
What a surprise; it's a billion years later and you're still not cool. I'm done hiding out. Everybody out there is gonna know me soon.
Patience St Pim [S08E08 Elemental]
The encounter re-awakens Slime Princess' elemental powers. Patience St Pim anonymously attacks the Candy Kingdom and successfully manages to coax Bubblegum into unlocking her own powers as well. Bubblegum is able to improve the efficacy of her abilities by applying her knowledge of chemistry to produce new, more complicated sugar-based compounds, such as the explosive combination of soda and mints, after consulting with Chatsberry, one of her past lives. [S08E19 Jelly Beans Have Power]
After Finn, Jake, BMO, and Susan leave for the Islands, Patience begins to enact her plan to cast the elemental purification spell over the Land of Ooo. She hypnotises and rounds up the other three Elementals, but can't find an appropriate power source for the spell. That same evening, Ice King is approached by Betty. Given her previous plans to save him from the crown haven't worked, she decides to try a more direct approach, and invites him on a date. Ice King is more than thrilled. But when Betty isn't able to coax any of Simon's old memories out of Ice King's twisted and broken mind, she freaks out and ends the date abruptly. After a conversation with Tiny Manticore she realises that her efforts may be fruitless, and it might be better to just make the most of what she has.
Maybe you're going after someone who doesn't exist anymore. Why not take him as he is? After all, you've been through a lot of changes yourself.
Tiny Manticore [S09E03 Bespoken For]
Betty travels back to the Ice Kingdom with a new plan; to try to get to know the Ice King. But Patience, seeing the considerable magical power that Betty holds, freezes her and uses her to power her elemental purification spell. With no Finn and Jake to stop her, Patience is successful. [S09E03 Bespoken For]
The entire Land of Ooo is divided into four distinct quadrants, each corresponding to one of the four elements; ice in the north east, slime in the south east, fire in the south west, and candy in the north west. The Elementals themselves become massively augmented versions of themselves. Princess Bubblegum becomes an immense tower of gum. Additionally, all of the inhabitants have their minds altered to reflect the element of their quadrant. Those in the ice quadrant become permanently sad and depressed. Those in the slime quadrant become competitive and envious. Those in the fire quadrant become angry and hateful. And those in the candy quadrant are trapped in a constant state of unrelenting bliss. [S09E02 Skyhooks, S09E04 Winter Light, S09E06 Slime Central, S09E07 Happy Warrior]
The princesses and I are the Elementals incarnate. But the others didn't want to play with me. They denied their precious birthright. So I cast a mega-spell that tapped into their true selves, but the spell worked too well. Instead of embracing their powers, they were overrun by them. I have distilled them into something monstrous.
Patience St Pim [S09E04 Winter Light]
A small selection of Ooo's inhabitants escape these fates. Ice King and Gunter escape to Cloud Kingdom, along with Ice King's stolen wire hangers which he calls his "skyhooks". Sweet P is unaffected by the changes due to his true nature, but his parents are converted to candy and he runs away from them. Lumpy Space Princess is unaffected due to being the Lumps Anti-Elemental. Cinnamon Bun is in the Fire Kingdom at the time, and his flame shield protects him from the changes. [S09E02 Skyhooks, S09E03 Bespoken For, S09E09 Skyhooks II, S09E06 Happy Warrior]
Marceline somehow avoids conversion initially. She travels to the ice quadrant to confront Patience and tries to find out how to reverse the spell. She discovers that each element can be spread by songs pertaining to their related emotion, and tries to use this information to cure Bubblegum, but to no avail. She gives in to her fate and is converted to candy, becoming "Marshmaline the Campfire Queen". [S09E13 Ketchup]
Meanwhile, Finn, Jake, and BMO are on the boat on their way back to the Land of Ooo from the Islands. They meet Nightmare Princess, who trades them a vial of Nightmare Juice in return for the cargo of bananas they were hauling. They make land in the north west of Ooo; the quadrant which has been converted to candy. Immediately, they begin to realise the extent to which Ooo has changed. Their own Tree Fort has been turned to candy, and Fern, Neptr, Shelby the Worm, and Lemongrab have all been converted into permanently joyful versions of themselves. While Jake initially thinks this might not be such a bad thing, they quickly realise that the people they meet are empty shadows of their former selves, unable to experience any emotion other than joy. Sweet P has managed to avoid being candified, but is pursued by his terrifying candified parents. Wanting to get to the bottom of these bizarre changes, Finn and Jake learn that Princess Bubblegum is at the top of the tower. They meet Marshmaline on the way there. Princess Bubblegum reveals her new nature as the purified Candy Elemental and attempts to candify Finn and Jake, but they are fortunately rescued by Ice King, who uses the skyhooks as a grappling line to pull them up to the safety of his cloud. BMO is lost to the candy. [S09E01 Orb, S09E02 Skyhooks]
Together, Finn, Jake, and the Ice King organise a mission to Patience's home in the ice quadrant to rescue Betty. They meet Carol the former cloud person, who has been frozen into a solid icy state. After they tell her they are planning on "taking out" Patience, Carol goes ahead of them and warns Patience of their arrival. They meet Patience at a reception she had planned for the other Elementals, but which the other Elementals never attended. While Patience regrets her decision to enact the spell, she is too apathetic towards the entire situation to actually bother trying to help them fix it. Jake is almost converted to one of the ice people, but Finn and Ice King manage to escape with him and the frozen Betty, and thaw them both back in Cloud Kingdom. Finn gives Betty the Farmworld Enchiridion and she begins studying it to try to figure out a counter-spell to revert things back to normal, and comes up with a plan. She tells Finn and Jake that if they retrieve the crown jewels from the three elemental princesses, she'll be able to cast the counter-spell. But her actual plan is something different... [S09E04 Winter Light, S09E05 Cloudy]
Finn and Jake's first stop is the slime quadrant. Slime Princess is hosting a competitive roller-skate dance party. Finn and Jake meet LSP and compete to be assimilated into Slime Princess' huge form so they can grab her crown and escape. But during the assimilation, Jake gives in and lets himself be taken. Luckily, Finn grabs the crown and LSP, who can't be assimilated due to unknowingly being the Anti-Elemental, saves him. They are kicked out of the party and head back to Cloud Kingdom together.
I got the jewel... but I lost Jake... You're not a slime person?
No, I totally faked it. I just saw this lumpalicious party and I was like, "These are my people!" But even though I shoplifted this super-cool outfit, I still didn't fit in.
Finn and LSP [S09E06 Slime Central]
Next, they visit the fire quadrant to retrieve Flame Princess' jewel. The entire kingdom is in one giant ongoing senseless brawl. They meet Cinnamon Bun, who takes them to the old throne room. They find Flame Princess there, who has been transformed into a giant dragon. Finn gets caught up in the fighting and ends up being converted into an enraged flame person. LSP tries to convince everyone to stop fighting each other. The flame people actually listen to her, but instead of fighting each other they begin marching on the candy quadrant. [S09E07 Happy Warrior]
LSP uses gum from Princess Bubblegum's tower to remind Finn who he really is, and he returns to normal. Meanwhile, Bubblegum begins exploiting the power of song to expand her own dominion. She candifies the invaders from the fire quadrant, and begins to extend her influence into the other quadrants. Patience St Pim, watching her new home melt and candify, decides that her best option is to re-freeze herself and try again in another thousand years or so. Finn is able to snag the jewels from Princess Bubblegum and the now candified Flame Princess, and gives them to Betty, but she simply takes the jewels and the Enchiridion and flies away without him. She has her own plan. [S09E08 Hero Heart, S09E09 Skyhooks II]
People say you shouldn't live in the past. But I say: Why not? This book is strange, but when you puzzle it out, it's mostly all charges and frequencies. Instead of fixing Ooo, I can use these jewels to make a portal to take me back in time and find Simon before he discovers the crown! This time I won't let him put it on. I'll drop it in a volcano before that happens. Things will be back to being just me and Simon. And you won't exist! No more Ice King. No more magic Betty. Maybe I can even stop the Mushroom War! My wonderful Simon will never become this sad pathetic creature strewn before me. I thought I could do it, but I can't. Being with you is like looking at my old life through a fun-house mirror. It's driving me mad! Goodbye, Ice King.
Betty [S09E09 Skyhooks II]
But Ice King doesn't like the sound of that. He interrupts Betty's spell casting halfway through and prevents her from creating the portal to the past. Instead, it backfires and sends her to Mars. Meanwhile, Finn and LSP figure out how to activate LSP's anti-elemental powers, and with the help of the elemental jewels and Evergreen's crown she is able to save the whole of the Land of Ooo by turning it back to normal. In some cases, she converts things even more "back to normal" than usual; her powers undo a lot of additional transfiguration magic. Jake is released from his assimilation with Slime Princess, but in the process he loses his yellow pigmentation and takes on a blue hue more accurate to his true heritage. Sweet P grows back his missing horn. And unbeknownst to anyone else, Gumbald, Lolly, and Chicle are released from their imprisonment. [S09E09 Skyhooks II, S10E05 Seventeen]
Following the elemental takeover, Fern suffers a massive loss of confidence in his own abilities. He believes that the fact he was unable to stop Patience proves that he is an inferior hero to Finn.
Meanwhile, a great threat looms over the Land of Ooo. When the Lich's hand fell into the portal in Farmworld, it duplicated across every dimension in the Multiverse. The copy which ended up on Earth begins attempting to awaken Sweet P's inner darkness by whispering to him at night. One night, he runs away from home to escape the whispers and ends up running into Finn and Fern. Finn tells Fern to guard Sweet P while he goes to fight the Lich, just in case Sweet P turns evil. They return to the Well of Power for a final showdown. Across the Multiverse, the same battle is happening in every dimension.
You've bested me in many worlds, child. But I always return. While the mortal world doubts and questions, I know exactly what I am. I am the ceaseless wheel. The last scholar of GOLB. I am your doom.
The Lich [S09E13 Whispers]
Sweet P, unwilling to stand by while Finn fights the Lich, knocks out Fern and goes to help. In the end, it is Sweet P who saves Finn from near death and defeats the Lich, making his final decision to be good rather than evil. This is the last time the Lich is ever known to rise. [S09E13 Whispers]
Being knocked out by Sweet P and missing the fight against the Lich further compounds Fern's insecurities and he begins to consider drastic action.
I don't get it. Why isn't it working out being myself? Finn's off having fun defeating losers. I can't even guard a baby. It doesn't matter how hard I try. I'll always just be in the shadow of the real Finn. Unless I could become... the only Finn.
Fern [S09E13 Whispers]
Eventually, Fern goes through with his plan to replace Finn. He tricks Finn into accompanying him to a ziggurat dungeon where he locks him inside a stone chamber. Finn, realising that he has been betrayed, discovers that his bionic arm comes with a myriad of additional features, including a rock drill which he uses to escape the chamber. It also has a "weed whacker" feature. He intercepts Fern and they battle it out. In the end, Finn accidentally disintegrates his clone. He returns to the Tree Fort alone, distraught by the belief that he has killed Fern. [S09E14 Two Buckets]
Jake tries to take his changing body with an open mind, insisting that despite his new appearance he is still the same person. But his somewhat monstrous form scares BMO and makes other people uneasy. After meeting Jermaine in a dream again, they meet up in real life at Jermaine's new art studio in the wastelands. Jake is surprised to find that Jermaine has switched from painting realistic landscapes to painting abstract art and suspects that something is wrong with him. But he makes an attempt to understand these changes.
The shapes are always changing. Changing is their normal state, like us. Even if we're not changing on the outside, we're changing on the inside constantly. There's some stuff about me that I've been ignoring for a long time. I'm afraid of that stuff. But it's part of who I am. As long as I know the shape of my soul, I'll be alright.
Jake [S09E10 Abstract]
In doing this, Jake comes to admit that he is changing himself. This acceptance is enough to return his body back to its ordinary yellow state, but Jake is still left with a lot of questions about his past and origins, having been deprived of this information by his parents. [S09E10 Abstract, S06E16 Joshua & Margaret Investigations]
Some time later, Kim Kil Whan asks Finn and Jake to investigate some strange happenings at one of the properties owned by his company: the former residence of Finn and Jake's family, Joshua and Margaret Investigations. They discover that the perpetrator is Clock Bear, one of the creatures who escaped Doctor Gross' menagerie. He causes several "time slips" between the 980s and 1001 AMB, making the house seem haunted. This also allows the future versions of Finn and Jake to subtly interact with their dead parents, and future Jake witnesses his own unconventional birth. After repairing Clock Bear and stopping the time slips, Jake meets a mysterious figure in an alleyway beside the house. It turns out to be Warren Ampersand, the shape-shifter who is Jake's biological father, and Jake willingly goes with him to his home planet of Nerraw. [S10E08 The First Investigation, S10E10 Jake the Starchild]
As he has done with many of his previous children, Warren Ampersand tricks Jake into stretching while wearing a special belt so that he can siphon off his son's stretchy essence and extend his own lifespan at the expense of Jake's. However, Jake is able to switch their belts and carries out a counter-trick. Old and near death, Warren tries to escape Nerraw and travel to Earth to find Jake's children and drain their power instead, but his spacecraft is grabbed by Jake, who throws him into the black hole orbiting the planet. Jake is left stranded alone on Nerraw. [S10E10 Jake the Starchild]
Leave my kids alone!
If you destroy me you'll be stuck on that rock forever!
My pups are worth it!
Jake and Warren Ampersand [S10E10 Jake the Starchild]
After Jake has been missing for five weeks, Finn and Jermaine travel to Mars on a mission to rescue their brother, thinking that Normal Man will be able to help them. They find that Normal Man, who has taken the title King Man, has made Mars into his own kingdom. He seems to rule well, although he has his subjects maintain numerous statues and shrines to his late wife Margles. Betty is one of his subjects, having been teleported to Mars following her failed attempt to travel back in time. She is busy filling an immense hole with sand one grain at a time, which Normal Man claims will help her get over the loss of Simon. To locate Jake, Normal Man tells Finn and Jermaine that they must travel through a set of challenges to activate a "space telemetry capsule" which will teleport him back to Mars. The challenges represent the respective emotional turmoil of Finn and Betty, with the intention being to help Betty learn to move on. They reach the end and Jake is successfully rescued. But Normal Man's plan to help Betty ends up having the opposite effect on her.
And you, Betty. Finally you've learned that most pressing of lessons. That sometimes, for our own good, we must accept the loss of that which we hold most dear.
Nope. I've learned that I just gotta work even harder to get it back. Like, did you see Finn in there? He was indomitable. So as I stared into that endless white void, I came up with a plan. For me to save my Simon, and for you to finally pull Margles back from the maw of GOLB...
Normal Man and Betty [S10E11 Temple of Mars]
Finn also gets briefly trapped far from Earth, after being abducted to the Vanishing Point for breaking his oath. Princess Bubblegum builds a time machine powered by the last of the Sleeping Fire Giants, and sends Jake to the Vanishing Point to rescue him. [Beginning of the End #2]
Before the elemental takeover of Ooo, the first candy people, Uncle Gumbald, Cousin Chicle, and Aunt Lolly, are still trapped in their docile forms as Punchy, Crunchy, and Manfried respectively. Even in this state, however, the three show a greater degree of leadership than most of the other candy people, and Princess Bubblegum appears to keep a close eye on them. [Banana Guard Academy #4, S06E23 The Pajama War, S07E13 The Dark Cloud]
And instead of a wax idol, they shall have a true princess. Wrought of iron, with teeth of diamonds. Her heart is ice. Her will is fire. Princess Crunchy the Unforgiving!
Crunchy [S07E13 The Dark Cloud]
Manfried's a good leader because we can always see him.
Mr. Cupcake [S06E23 The Pajama War]
Following the reversal of Patience St Pim's elemental spell by Lumpy Space Princess' anti-elemental influence, the effects of the Dum Dum juice from eight hundred years prior are also reversed. The trio lay low for a while. Their absences are noticed by Bubblegum, who has missing posters put up in and around the Candy Kingdom. They commandeer the ziggurat and turn it into their base. Soon, Gumbald comes across the remains of Fern following his "death" at the hands of Finn, and collects up the pieces. Gumbald begins experimenting with creating candy based life, just like his niece Princess Bubblegum, and creates some monsters with which to gauge the strength of the modern Candy Kingdom and its allies. [S10E02 Always BMO Closing, S09E14 Three Buckets]
One of the monsters he creates is a banana fudge monster which begins attacking the banana guards' barracks at night. Finn and Jake are tasked with taking down the mysterious monster. However, Finn has been unable to slay any monsters since he killed Fern due to a paralysing sense of guilt which overcomes him every time he's about to deliver a finishing blow, and makes him see a reflection of Fern in the faces of his victims. With Huntress Wizard's help, he is able to find a way to overcome this paralysis by projecting Fern's face upon those he is trying to save, rather than those he is trying to kill, and he slays the beast (which Huntress names "the Grumbo"). Huntress Wizard, however, believes that his decisive actions in the face of guilt are for a different reason.
Yeah right. We both know you're totally in love with me.
Huntress Wizard [S10E01 The Wild Hunt]
Despite previously claiming that they are unsuitable for each other, Huntress shares a kiss with Finn. It is unclear what the subsequent state of their relationship is since it is never explored further. They seem to keep it casual. The Small Sword is destroyed during the fight. [S10E01 The Wild Hunt, Season 11 #6]
Gumbald's second anonymous attack occurs after BMO, while playing as a door-to-door salesperson along with the Ice King, sells a pouch of Finn's baby teeth to him in exchange for a silver goblet. Gumbald's mistake in this transaction is the fact that the goblet has his logo on it. Gumbald engineers the baby teeth into tiny baby tooth clones of Finn but they are easily defeated by Finn and Jake. Bubblegum, after recognising the logo on the goblet and given the disappearance of the three candy people, puts two and two together and realises that her family must have returned. [S10E02 Always BMO Closing, S10E04 Bonnibel Bubblegum]
The Candy Kingdom goes on high alert. Bubblegum hosts Finn's seventeenth birthday party but restricts the guest list to minimise risk. Despite these precautions, the party is intruded by an individual calling himself the Green Knight, who rides on a mechanical horse and has mysterious shielding technology which Bubblegum is unable to counteract. The Green Knight initially challenges Finn to a fight to the death but Finn manages to convince him that they should play party games instead. After defeating Finn, the Green Knight reveals that he is actually Fern, reconstructed and resurrected by his new allies: Gumbald, Lolly, and Chicle. The three gum people emerge from the mechanical horse, confirming Princess Bubblegum's suspicions that they had returned. But for now, their intention is merely to give Bubblegum a warning, and they decide to leave the party in peace.
For eight hundred years, you kept us imprisoned, prinzessin. It's your turn to be "happy" now. You've witnessed our superior technology, and watched your champion crushed. We'll go. For now.
Uncle Gumbald [S10E05 Seventeen]
Having recognised that Marceline is a major roadblock to their attempts to get revenge on Bubblegum, Cousin Chicle is dispatched to try to discover if she has a weakness. At the same time, Peppermint Butler is forging a new sword for Finn. He has it enchanted by Hunson Abadeer and names it the Night Sword. Hunson wishes to see his daughter so Finn and Jake escort him to Marceline. At Marceline's concert later that night, Chicle attempts to use their shaky relationship to his advantage and convinces a group of ghosts to beat up Hunson, but Marceline and her father escape with help from Finn and the Night Sword. [S10E07 Marcy & Hunson]
Gumbald floods the Land of Ooo using a copy of the Enchiridion from another dimension and attempts to frame Princess Bubblegum so that he can replace her as ruler of the Candy Kingdom, but this plan is foiled by Finn, Jake, BMO, and Marceline. [Pirates of the Enchiridion]
By now, Gumbald, Lolly, and Chicle have established their own kingdom named Gumbaldia. The conflict between the Candy Kingdom and Gumbaldia escalates into a full scale arms race, with both sides believing that the other is giving them no choice but to build up their armaments. Gumbald begins amassing an army of his own candy-based creations and building a massive robot named "The Cake" to rival the Gumball Guardians. He also establishes what he calls the "Legion of Candy Kingdom Haters", consisting of many of the Candy Kingdom's old enemies; Ricardio, Bandit Princess, Samantha, Peace Master, Me-Mow, Pete Sassafras, Ash, Sir Slicer, Scorcher, the Green Knight, and Ice King (who thinks he might have been invited by mistake). Bubblegum establishes her kingdom's defences and begins arming the banana guards for what looks like an inevitable war.
I don't think going to war with your uncle is a good idea.
I don't have any choice. By building an army, he's forcing my hand.
It seems to me that all these rhubarbs down through history don't do nobody no good.
Finn, we all love how sweet you are, but sometimes we just have to buckle down and do things the ugly way.
Finn and Princess Bubblegum [S10E12 Gumbaldia]
And so, the Princess was mother to her own Uncle. And that made him mad. But she had friends, and he had friends. So they decided to have a bad fight. The biggest fight that Ooo had ever seen.
BMO [S10E13 Come Along With Me Part 1]
Finn and Jake secretly leave on a last ditch diplomatic mission to Gumbaldia to try to talk Uncle Gumbald, Aunt Lolly, and Cousin Chicle out of going to war against the Candy Kingdom. However, Lolly uses this as an opportunity to carry out a devious plan. The three of them pretend to be enamoured by Finn's diplomacy and send him back with a peace treaty. They also splash Finn and Jake with liquid from what they call their "celebration bucket" which is in fact Dum Dum Juice. Some of it ends up getting on Chicle but he manages to escape the room before Finn and Jake see his transformation back into Crunchy, so they don't realise what's going on. Fortunately, Princess Bubblegum does not touch Finn or Jake when they return to the Candy Kingdom. Peppermint Butler, however, is not so lucky. The Dum Dum Juice converts him into a stupefied baby version of himself. Princess Bubblegum, realising that the entire diplomatic mission was a botched attempt on her life, immediately mobilises her army, and the Great Gum War officially begins. [S10E12 Gumbaldia]
The two armies set up their respective camps on each side of a canyon between the territory controlled by the Candy Kingdom and that which has already been annexed by Gumbaldia. Despite some final efforts on the part of Finn and Marceline to try to convince Princess Bubblegum to rethink things, she is adamant on solving things the ugly way.
Well... I know you're under a lot of pressure here, but I just wanna ask you to reconsider. I mean, I don't want to flaunt my suffering cred, but I've lived through something like this once before, and... I'm just not really trying to help start that all up again.
I understand, Marceline. I really do. But I just can't see another way out of this. Look, I've gotta go. Let's talk more when this is all over. Wish me luck, okay?
Marceline and Princess Bubblegum [S10E13 Come Along With Me Part 1]
Finn and Jake, while scouting for the Candy Kingdom, spot some unexpected visitors above the battlefield; Normal Man, Betty, and the still comatose Maja. They bring this information back to Bubblegum, but there isn't much time to think about this development before things start kicking off.
After Huntress Wizard captures a Gumbaldian scout who has already relayed Princess Bubblegum's tactics back to Gumbald and Lolly, Bubblegum decides she has no choice but to begin the battle immediately. The two armies meet in the middle of the canyon and establish their lines, each waiting in a stand-off for the other to attack first. On the side of Princess Bubblegum and the Candy Kingdom stands Bubblegum's army of banana guards and the two Gumball Guardians, as well as notable allies such as the Duke of Nuts, the Earl of Lemongrab, Flame Princess, Slime Princess, Huntress Wizard, Lady Rainicorn, Lumpy Space Princess, Jake, and Finn. On the side of Gumbaldia stands the new army of candy people created by Gumbald, as well as The Cake and the Legion of Candy Kingdom Haters.
Now that both sides have seen the full might of the other, Finn manages to convince Bubblegum that Gumbald could have changed his mind about wanting to fight the Candy Kingdom, and there could still be a chance to de-escalate things. Remembering all that Finn has done for her, in this life and before, Bubblegum agrees to give diplomacy one last try. Finn, Jake, Princess Bubblegum, Gumbald, and the Green Knight meet at the centre of no man's land. As Finn expects, this doesn't go any better than the previous attempts to talk down Bubblegum and Gumbald, but this time he has a trick up his sleeve. Jake pops the mysterious vial of nightmare juice given to them by Nightmare Princess on the boat trip back from the Islands, and the five of them fall unconscious and enter a shared dream. [S10E13 Come Along With Me Part 1]
During the dream, Gumbald and Bubblegum are each shown the tormented lives which the other have lead ever since the day Gumbald first betrayed his niece. Princess Bubblegum has let her kingdom and her people grow into something she no longer feels she can support, and Gumbald has been trapped, unable to assist her in any meaningful way. Meanwhile, Finn and the Green Knight also resolve their own conflict. Jake finds their shared vault buried deep within the fabric of the dream, and together they confront all their greatest fears. One of them is the Emissary from Beyond; the creature who embodies the cursed spirit of the Grass Sword. Fern impales the creature with a chair leg, killing it swiftly. The five dreamers all gather on a beach at the end of the dream, while the Cosmic Owl flies overhead to cement its events into reality.
After waking up, Fern finds that without the Grass Sword's curse to hold him together, he is disintegrating. Meanwhile, Princess Bubblegum decides that she wants to come to a peaceful resolution.
I'm so sorry for what I put you through for all those centuries. The Candy Kingdom was your dream, and I took it from you.
Bonnie, that means so much to me. Come; from now on, we'll live in peace.
Princess Bubblegum and Uncle Gumbald [S10E14 Come Along With Me Part 2]
However, Gumbald attempts to double cross her one more time. As they are approaching each other for an embrace, Gumbald prepares to draw a vial of Dum Dum Juice. But he is tripped up by Aunt Lolly and he spills the potion on himself instead. He is transformed back into Punchy once again. Aunt Lolly agrees with Bubblegum's desire for peace, and they decide that Gumbaldia and the Candy Kingdom will be allowed to coexist without any further conflict. The Great Gum War is over. But the day is not.
And so, in the end, they decided not to have the big fight.
Oh, so you meant like, the end of the war. I thought you meant like, the end of the world.
No no no... That happened next.
BMO and Beth [S10E14 Come Along With Me Part 2]
Just as the armies are beginning to disband, a portal appears in the sky above the canyon. Normal Man falls through it, shortly followed by the enormous figure of GOLB; the embodiment of chaos and the most powerful being in the Multiverse. Betty's new plan is revealed: she wants to harness GOLB's ability to revert things to their "essential forms" in order to remove the curse of Evergreen's crown from Simon once and for all. But while she is trying to cast a spell to have this happen, GOLB begins to attack. Many of the Gumbaldian soldiers become amalgamated into a frightful monster which wreaks havoc upon both armies. The Legion of Candy Kingdom Haters flee the battle, but Aunt Lolly remains, and fights using the Cake alongside Princess Bubblegum's Gumball Guardians and her other allies. But this is not enough; the combined forces of both kingdoms cannot slay the monster. The Gumball Guardians, which have loyally served the kingdom for hundreds of years, are destroyed. One of them is smashed open, and the other is turned into a second hideous monster.
In the midst of the battle, some of the belligerents find the time to confess their love for one another in what could potentially be the final moments of their lives. Lemongrab and Lumpy Space Princess, who have been dating, make their relationship known by kissing on the battlefield. Marceline also finds herself revealing her true feelings after believing that Princess Bubblegum has been killed by the amalgamation. After all they've been through in the past few years, having rekindled their friendship and eventually their romance, Marceline can't bear the idea of losing her a second time. She pummels the monster to pieces using her latent ability to summon the Dark Cloud, and upon discovering to her relief that Bubblegum was saved by her emergency force field, the pair share a kiss.
Even back when we weren't talking, I was so afraid something bad would happen to you and I wouldn't be there to protect you and... I don't wanna lose you again.
Hey... I'm a tough gum. Nothing never happening to me. Never.
I know, I'm... Girl, you phrased that so weird.
I might have a concussion.
Marceline and Princess Bubblegum [S10E15 Come Along With Me Part 3]
Meanwhile, Normal Man seeks out Ice King and encourages him to try to talk to Betty, to prevent her from casting the spell. Normal Man, Ice King, and Finn fly up to Betty's flying carpet, where they find her attached to Maja with jumper cables. Ice King still doesn't recognise Betty, which only succeeds in further angering her. This surge of emotion travels down the jumper cables and awakens Maja from her coma, but her ability to harness sentimentality is overloaded by Betty's rage and she dies in a violent explosion. The explosion knocks Ice King and Betty directly into the open mouth of GOLB, and Finn leaps in after in an attempt to rescue them. He makes it into the mouth just before GOLB knashes his teeth together and traps them inside. Finn's bionic arm is severed from his body and falls to the battlefield below. Within GOLB's stomach, the three begin to get "digested"; they are stripped down to their most fundamental forms as part of the process of removing them from existence. Finn remains an amputee, as he has always been destined to lose his arm. Betty returns to how she was before she was driven mad by Magic Man's powers. And finally, Ice King is reverted back into his true fundamental form: Simon Petrikov. Evergreen's crown appears to deactivate. Betty is thrilled that she has finally succeeded in curing Simon's madness, and they share their first kiss since before the Mushroom War. But with only minutes left until they are consumed by GOLB, her joy is short-lived.
It's good to see you, Simon.
It's good to be seen.
Betty and Simon [S10E15 Come Along With Me Part 3]
The forces of the Candy Kingdom and Gumbaldia have been largely defeated by this point. Despite having taken a beating from the enraged Marceline, the amalgamation reconstitutes its body, and together with the turned Gumball Guardian it begins to rampage through the Land of Ooo. Jake uses the full extent of his powers to take on the monsters, but even he is not strong enough. The monsters destroy a large portion of the Candy Kingdom's capital, and to Jake's horror they completely and irreparably obliterate the Tree Fort. [Season 11 #1, S10E15 Come Along With Me Part 3]
Jake, shocked and alone, curls up into a ball in the wreckage of his home until he is found by BMO, whose faceplate was broken during the destruction of the Tree Fort but who is otherwise unharmed. BMO begins singing to Jake, which attracts the attention of the monsters. But to Jake's surprise, BMO's singing appears to repel the monsters and make him invulnerable to their attacks. Marceline and Bubblegum fly past at this point, and Bubblegum realises what's happening.
Oh duh! GOLB is discord. It's the harmony. Harmony hurts them!
My art is a weapon!
Princess Bubblegum and BMO [S10E16 Come Along With Me Part 4]
Together, they head back to the battlefield where Bubblegum orders all of her remaining allies to harmonise along with BMO's song. With the combined harmony and focussed magical intention of all of the kingdom's friends, the song begins to easily penetrate GOLB's previously indestructible skin, boring a hole all the way through to his stomach. Finn and Simon, who were about ready to give up, suddenly find a route open for them to escape through. But Betty has another idea. She realises that the crown has not deactivated. It has merely reverted to how it was before the original Gunther wished to be like his master Evergreen. It no longer turns the wearer into an ice elemental. Instead, it will grant its wearer their deepest truest wish, just as it was originally intended to do.
Go. There's something I have to do first. I figured out what's wrong with the crown. It reset! Just like us! It's in its primal wishing form now. This world will end unless GOLB is banished so I'm gonna make... a wish. I have to do it here. The crown could revert once we leave. I gamed it out. I'm sorry for messing everything up.
Betty [S10E16 Come Along With Me Part 4]
Finn and Simon escape GOLB's innards, but the hole formed by the music closes up behind them, leaving Betty trapped. Within GOLB, she attempts to wish for his banishment, but it fails. Not even wish magic can defeat the ultimate power in the Multiverse. So instead, she wishes for Simon's safety, by any means necessary. The crown does not destroy or banish GOLB. Instead, it merges together GOLB's consciousness with that of Betty. Under Betty's influence, the new entity leaves Earth peacefully to a destination unknown. The crown falls to the ground, its wish once again reset. It is picked up by Gunter, and although Jake initially panics, thinking that Orgalorg is going to try to use it to do something evil, he instead wishes for something far more innocent. Gunter, like Evergreen's dinosaur servant before him, wishes to be like his master. He transforms into the likeness of the Ice King, a happy babbling individual who becomes known as the "Ice Thing".
Finally, the conflict is over and the day is won, but not without its losses. Simon is distraught by losing Betty for the second time. And without the Emissary from Beyond holding him together, Fern has spent the last of his energy fighting alongside his friends.
Hey Finn... I'm not doing so good. I just wish I could see the tree house one more time.
Yeah dude... of course. Let's go there right now.
That's okay. Just promise to plant me there.
Fern and Finn [S10E16 Come Along With Me Part 4]
He disintegrates in Finn's arms, leaving behind nothing but a seed. Finn and Jake plant the seed amongst the wreckage of the Tree Fort, where it rapidly grows into a new tree with the Finn Sword embedded in its upper branches. [S10E16 Come Along With Me Part 4]
But what happened to Phil or Jake after that?
Eh, y'know. They kept living their lives.
Shermy and BMO [S10E16 Come Along With Me Part 4]
Although the war is finished, the adventures of Ooo's inhabitants are far from over.
Immediately after the war, Princess Bubblegum begins the process of rebuilding the parts of the Candy Kingdom which were destroyed. A future version of Hunson Abadeer abducts Finn and Jake a thousand years into the future for help with his devious plan to erase Marceline's memories of Ooo, but his plan is foiled by Finn, Jake, Marceline, Bubblegum, and Simon. Additionally, the present day version of Hunson Abadeer recognises that what his future self did was wrong, meaning those events might have been retroactively prevented. Finn obtains a new sword at some point. It is not known why he stopped using the Night Sword. [Season 11 #1 to #4]
Aunt Lolly becomes the ruler of Gumbaldia, which peacefully coexists alongside the Candy Kingdom. Punchy and Crunchy, the Dum Dum versions of Gumbald and Chicle, happily reintegrate into Candy Kingdom society, although their true selves are presumably still trapped within their minds. [S10E16 Come Along With Me Part 4, Season 11 #5]
At some point, Simon travels to the Time Room to try to wish Betty back into existence, but just like Magic Man before him, he discovers that not even wish magic can bring back someone who has been lost to GOLB. [S06E38 You Forgot Your Floaties, S10E16 Come Along With Me Part 4]
After a while, Marceline mostly moves out of her house and into the castle to live permanently with Princess Bubblegum now that their relationship is out in the open, taking up the offer which Bubblegum initially gave her following the defeat of the Vampire Court. Finn and Jake remain undecided about where they should live, initially just camping out under Fern's tree amongst the wreckage of the Tree Fort. Jake considers moving in with Lady Rainicorn, or suggests that they both move into Marceline's old house or into the Candy Kingdom capital. [Season 11 #5]
This dilemma is further complicated by the arrival of the humans in Ooo. Several ships full of humans finally make the journey from the Islands to the mainland and establish a colony named "Humantown", but their isolationist leader, Leader Malloy, establishes a policy stating that contact with the rest of Ooo and its "mutant" inhabitants should be kept to a minimum. This means that if Finn goes to live there, he will have to leave the colony to visit any of his friends, including Jake. [Season 11 #5, Come Along With Me Part 4]
It might be better for all of our people if you simply... leave us alone. Don't get me wrong! We appreciate your offers of assistance. But for the moment, we believe Humantown should remain isolated. There is one person I will allow to visit Humantown... Young Finn, here! As the only known human living in Ooo, you're an honorary citizen. You've got entry and exit permissions to the city, any time. And if you ever want to move in, you're more than welcome. As far as I'm concerned, this is where you belong.
Leader Malloy [Season 11 #5]
The human colony also brings a Minerva-bot to the Land of Ooo, giving Finn an opportunity to speak to his mother again; or at least, whatever she became after uploading her brain into an AI. They talk about all the things which have happened in Ooo since Finn visited the Islands, and he opens up to her about the death of Fern.
I had a brother. Not, like, a brother from you. Not like Jake and Jermaine, either. His name was Fern. He was... He was me, but sent through time and turned into a sword, and then merged with a weird grass thing... I don't really know what he was. And neither did he. He wanted to be a hero, like me. Really, he wanted to be me. But he already was me, kinda. And he lived in a world that had a me. So he didn't know what he should be. What he could be. I think he died before he could find out.
Finn [Season 11 #5]
Humantown is attacked by a monster, which turns out to be a robot under the control of Leader Malloy for testing whether Finn would come to the colony's aid. Finn, disappointed by this deception, chooses not to live in Humantown. Instead, with the help of many of his friends, he builds a wooden house for himself halfway between Humantown and the Candy Kingdom. [Season 11 #5 and #6]
Normal Man returns to Mars as its ruler. However, the Martians revolt against their leader after he accidentally unearths and detonates a field of "stank mines" from the Martian Independence Era which cause the colony to become uninhabitably smelly. With no magic to help him fix the mess, the Martians abandon Normal Man on Mars to seek out new homes. [Marcy & Simon #5]
It is not known whether or not Lumpy Space Princess and the Earl of Lemongrab remain in their relationship. Lumpy Space Princess is crowned ruler of Lumpy Space, meaning that her parents have finally decided that she is responsible enough for the position, which finally earns her the respect of the other princesses of Ooo who previously accused her of not being a "real" princess. Lemongrab seems to have found true contentedness for the first time. He hires Jermaine to paint a mural on his bedroom ceiling. [S10E16 Come Along With Me Part 4]
Another unexpected relationship is that of Ice Thing and Turtle Princess. He accidentally proposes to her after one of his gems falls out and lands in a doughnut, and they get married soon after. [S10E16 Come Along With Me Part 4]
Simon embarks on an "apology tour" of the Land of Ooo to make amends for all the bad things he did while he was the Ice King. He grants Gunter (AKA the Ice Thing) permission to rule to Ice Kingdom in his stead. Marceline organises for Flame Princess to thaw the parts of Cloud Kingdom which Ice King froze around a year prior, causing Cloud Kingdom to rain for the first time in centuries. It's possible that this is how Carol, having transitioned through the other two phases of water, finally becomes a water nymph. However, while all of this is very nice, Simon begins to lose his memories of his time as Ice King. [Marcy & Simon #1, S10E16 Come Along With Me Part 4, S06E25 Astral Plane]
And yes, those were my darkest days, but they hold some of my brightest memories, too. Hanging with the two of you. Becoming a wizard. Watching Marceline grow up. My last days with Betty. I can't forget it! It's... it's who I am now.
Simon [Marcy & Simon #1]
Bubblegum tries to restore these memories by extracting them from the copy of Simon's consciousness stored in Evergreen's crown, but this is unsuccessful. With the help of Peppermint Butler, who has been relearning his dark magic since the Dum Dum juice was used on him, they go to the Nightosphere to try to get Hunson Abadeer's help. But Hunson gets jealous of Simon's relationship with his daughter, and rather than just restoring Simon's memories of his time as the Ice King, he casts a "Character Curse". The personalities of Simon and Ice King battle for control of his body. Princess Bubblegum decides that the only way to cure his split personality is via a true love's kiss; specifically, a kiss from Betty. But Betty is still trapped in a merged state with GOLB, so Finn, Jake, Simon, Marceline, and BMO gear up for a journey through the Multiverse. [Marcy & Simon #2 to #4]
You risked it all for the good of Ooo, sacrificing yourself for me. But I am nothing without you, Betty. You released me from my mental prison, but I cannot truly be free until you are. I will save you from the dark dungeon of GOLB's grasp. I'll fight for you as you fought for me. I will find you, Betty, or die trying.
Simon in a letter to Betty [Marcy & Simon #4]
Princess Bubblegum creates a sword for Finn which allows him to tear holes between any dimension in the Multiverse. After some time spent searching, they obtain a portal gem from Normal Man, who has been collecting magical artifacts in his attempt to disperse the stink. He gives away the gem in the hope that if the crew are able to defeat GOLB, he might finally have avenged the death of Margles. They also obtain a key from Pillow World capable of activating the gem, and travel to the Time Room. [Marcy & Simon #5]
Note: The Dimension Sword contradicts the fact that travelling between dimensions has previously been depicted as quite a difficult ordeal. This issue also suggests that Pillow World is a real place, even though a lot of the symbolism in Puhoy suggests that it was imaginary.
In the Time Room, Prismo grants each of the travellers a wish. They all nominate Marceline to make a wish on their behalf, so she wishes to open a passage to the fusion of GOLB and Betty. They discover that GOLBetty has exiled themself to the Anti-verse, a place where there is nothing, so that GOLB can do no harm. Simon and Betty manage to share a kiss and cure Simon's memory problems, but GOLB reacts violently and swats Marceline into the void. Watching from a viewing globe, Peppermint Butler informs Hunson Abadeer about what is going on, and Hunson heads to the Anti-verse to save his daughter. Hunson confronts GOLBetty, and is able to use his own power to split the fusion before escaping back to the Nightosphere with Betty and all the travellers. As thanks for Peppermint Butler's services in helping to save his daughter, Hunson re-ages him to adulthood. GOLB is left stranded in the Anti-verse, Betty is safe, and all is well. [Marcy & Simon #6]
Note: Finn, Jake, and Simon are all offered wishes by Prismo even though they have already taken their one wish; Finn's was to prevent the Lich from existing, Jake's was to overwrite the Lich's wish, and Simon's was to (unsuccessfully) bring back Betty. This is a continuity error.
Note: This section will only cover the plot-relevant comics belonging to the main series which ran from 2012 to 2018.
Instead of stealing the Enchiridion and accessing the Time Room, the Lich attempts to use the Bag of Holding to end the world. He succeeds in sucking a lot of people into the bag, including Finn, Jake, Ice King, Lumpy Space Princess, Marceline, and the entire Candy Kingdom including Princess Bubblegum. Several of the candy people get amalgamated into "Desert Princess", who is capable of controlling sand with her mind. Finn and Jake manage to burrow out the bottom of the bag and by working together with everyone else they eventually defeat the Lich and defeat him once and for all by throwing him into the Sun. The giant crater is filled in with sand from inside the Bag of Holding. Due to these divergent changes from the main storyline, some events of the main comic series must occupy a separate timeline to the show. However, the comics still appear to follow the general story of the show. [Free Comic Book Day 2012, Adventure Time #1 to #4]
Princess Bubblegum creates a time machine capable of transporting its user back to the moment at which it was first created, where the user will replace their past self. She destroys it after Jake misuses its power, so Jake gets Neptr to repair it. The repaired time machine transports a duplicate of Finn and Jake's minds fifteen years into the future, where they replace the minds of their future selves. Shortly after this, BMO accidentally creates two evil robots that begin to replicate themselves. [Adventure Time #6 to #7]
Note: This event takes place in 997 AMB when Finn was thirteen because Finn states that he is twenty eight after they travel forwards fifteen years.
By 1012 AMB, the robots are at war with the other inhabitants of Ooo. Finn, Jake and Bubblegum create a new time machine by vowing to spend the rest of their lives building a time machine and then sending it back to the point at which they made the vow. After a detour through the pilot episode and the events of Adventure Time #1, Finn and Jake travel back to the present, where they destroy the first robots and erase the timeline. [Adventure Time #7 to #9]
BMO becomes infected by Randall N. Byron's virus after using the same technique to allow Finn, Jake, and Marceline to play Super Guts Punch 3. The virus gains independence from its creator, taking the name "Ewlbo" and infecting many of the robots of Ooo until eventually being defeated by Finn, Jake, and Marceline. [Adventure Time #11 to #14]
Finn and Jake have several encounters with Magic Man over the course of the comics, where his mischievous schemes include stealing their voices, crashing Bubblegum's meeting with the Fancy Egg Folk, and stealing all the colour from the world. [Adventure Time #15, #40, and #74]
Ice King, along with Finn and Jake, re-discovers the dungeon he built with Hunson Abadeer and together they destroy the Echo of the Lich. [Adventure Time #16 to #19]
The Gum, the creation which Bubblegum made just before the birth of Lemongrab, takes over the entire Candy Kingdom and must be defeated by Marceline, Bubblegum, and Lemongrab. [Adventure Time #21 to #24]
Ricardio steals the Red and Blue Amulets from Princess Bubblegum and the Tree Fort and has to be defeated again by Finn, Jake, Marceline, and Bubblegum. They end up storing the amulets in a dungeon for safekeeping. [Adventure Time #25]
Things don't pan out well for Clarence and Ghost Princess in the afterlife. Clarence cheats on Ghost Princess with all the "smokin'-hot babe ghosts", who also constantly bully Ghost Princess, so she escapes the Fiftieth Dead World and returns to life. She decides to become a ghost hunter under the name "Anti-Ghost Princess".
So I escaped the 50th Dead World and returned to Ooo by sheer force of warrior will. Then I took my new name. Started my new business. And I vowed to ensure that no ghost would ever walk this land again.
Anti-Ghost Princess [Adventure Time #28]
She helps Princess Bubblegum deal with the Candy Kingdom's ghost problem. [Adventure Time #26 to #29]
A creature named the Mnemonoid feeds on stories, which are its main source of food. It attacks the Tree Fort and begins stealing Finn's memories since they are an excellent source of stories. Finn continues to live normally, but at periodic points he suddenly forgets several years of his life. [Adventure Time #31]
In 1004 AMB, Finn suddenly forgets the previous five years of his life, and is suddenly five years older with no memory of the intervening time. This alternate future is completely inconsistent with the show; for example, the Gumball Guardians are still operational. By this point, Bubblegum and Marceline are the co-ruling queens of the so-called "Candy Vampire Kingdom". Small fights frequently break out between the Fire, Sand, Water, and Air kingdoms. The Mnemonoid shows up again and begins stealing more of Finn's memories. [Adventure Time #32]
Finn suddenly wakes up in 1024 AMB, having forgotten the previous twenty years of his life. By this point, he is married to Phoebe the Flame Queen. The Sand Kingdom has annexed the Water and Air kingdoms and declared full-fledged war against the Fire Kingdom. The Mnemonoid attacks once again and kills Marceline by exposing her to direct sunlight, then begins stealing even more of Finn's memories. [Adventure Time #33]
Finn forgets another thirty-five years of his life, finding himself in 1059 AMB. He travels completely alone, suggesting that most of his other companions have passed away by now. The world is frozen over, which could be the result of the crown grieving the loss of Ice King like it did in the Farmworld timeline. Bubblegum, depressed and alone without Marceline, lives in the frozen war-torn ruins of the Candy Kingdom. Luckily, Finn is able to remember the plans for the time machine from the robot apocalypse timeline. He travels back to the present day and is able to erase the timeline by making Mnemonoid be friends with LSP, an infinite source of gossip which is able to sustain him much more effectively than Finn's memories. [Adventure Time #34]
Before the King of Ooo's election and subsequent dethronement, the Candy Kingdom's secret service foils a plot by which he was planning to invade the Candy Kingdom with an army of bears. [Adventure Time #41 to #44]
While exploring the basement underneath Joshua and Margaret Investigations, Finn and Jake accidentally break the statue of Gata. She suddenly comes back into existence as their long time friend and sister, as if she had never been erased, but Finn and Jake still can't remember who she is. She eventually sacrifices herself after realising that her continued presence could allow her evil mother to escape back into Ooo, and the world once again forgets she ever existed. [Adventure Time #46 to #49]
Arklothac, the cosmic ruler of Candy, is summoned to Earth and successfully defeated by Finn and Jake using the Sword of Lun. They also defeat Ng'zot Aa, the cosmic ruler of slime, after he tries to infect BMO. [Adventure Time #36 to #39 and #54 to #57]
Finn and Jake foil a plot by the leader of the 27th Dead World as well, who wanted to collect the youth from Ooo's inhabitants in order to craft an elixir and return to life. Finn and Jake end up with a large tub of the elixir. [Adventure Time #51 to #53]
Arklothac is released a second time and frees his compatriots, Zon the ruler of Fire and Ng'zot Aa the ruler of Slime. They can only be defeated by the Sword of Lun, but Finn is unable to use it a second time. He travels back in time to the Moon before the Mushroom War, in order to protect the sword and await its true bearer. Meanwhile in the future, Jake and Princess Bubblegum send the elixir of life through a portal back in time to make Finn immortal. Jake is slain by Arklothac just after this. Finn spends the next few years building a dungeon on the Moon to protect the Sword of Lun. Over a thousand years later, a future reincarnation of Finn named Penelope helps Finn defeat the Cosmic Elementals. They discover that she is the true bearer of the Sword of Lun, and the Cosmic Elementals are banished from existence. Finn is transported back to the present and forgets about the many hundreds of years he spent waiting on the Moon, and the timeline is erased. [Adventure Time #58 to #61]
As a result of the timeline shenanigans, Gata is released from her curse. The world doesn't remember who she is, but she is finally free. [Adventure Time #61]
Finn and Jake's remaining adventures within the comics are less grand in scope. They attend the Best Princess Ever competition, go on a balloon race, defeat a small army of their own clones, and attend the wedding of two characters named Casey and IBB. [Adventure Time #62 to #73 and #75]
Assuming the journey goes well, Tree Trunks' alien husband arrives back on his home planet and releases Princess Bubblegum's candy probes. They begin to establish a new candy kingdom among the stars.
We're going to fly Princess Bubblegum's probes back to our abandoned home planet. They'll have all the space they need to start their new candy kingdom. But our galaxy is so far away, I won't see you again for at least forty years.
Tree Trunks' alien husband in 1000 AMB [S08E17 High Strangeness]
One of Jake's daughters, Charlie, uses divination to predict her own future. During her twenties, she sees a vision which might represent her father's death. During her thirties, she has a son who she decides to name "Gibbon". She will apparently live into her nineties, although given the speed at which Jake has aged, this is probably referring to dog / rainicorn years rather than real years. [S08E11 Daddy-Daughter Card Wars]
While stuck at the Vanishing Point, Finn is granted three premonitions of three possible outcomes to his life:
All of these futures, no matter where they take you or what adventures you have, all of them must end the same way. Death. Sometimes your end is heroic, sometimes mundane, but every mortal existence must come to an end.
Chronologius Rex [Beginning of the End #3]
Note: The writer of Beginning of the End, Ted Anderson, has stated on his Tumblr that none of these outcomes are intended to be taken as canon, and he has no preference between the three.
If Bravest Warriors (Pendleton Ward's other cartoon) is part of the same continuity as Adventure Time, then it takes place approximately 74 years after the end of Adventure Time. This date assumes that the characters in Bravest Warriors use the CE date system, and also assumes that 0 AMB = 2010 CE.

Gravestone [BW S04E29 This Is Your Paradise]
Bravest Warriors has its own set of historical events, but unless it is confirmed to be a part of the Adventure Time continuity I will not include them in this timeline. The main evidence that the two shows are set in the same continuity is an image that was shown for a single frame during Chris' premonition in the episode Ultra Wankershim, which shows planet Earth with a large chunk missing, just like the Earth in Adventure Time. A popular fan theory is that Chris is descended from Finn, given their blond hair and similar personalities. It's also conceivable that the rest of the humans living on NeoMars are descended from the Islanders. However, this is all just speculation.
A future reincarnation of Finn named Penelope travels the Land of Ooo as an adventurer much like him. She has a pet tigercorn named Betty (no affiliation to the other Betty) who is probably a future reincarnation of Jake. Like most reincarnations of Finn, she is missing her right arm and has a bionic replacement. [Adventure Time #50 and #61]
She ends up having several interactions with individuals from the past. As well as helping Finn defeat the Cosmic Elementals as previously mentioned, she also discovers the Blue and Red Amulets in a chest in the dungeon built by Finn, Jake, Marceline, and Princess Bubblegum, and explores Princess Bubblegum's ruined library looking for help to fight the "awful offal abominations". She discovers Marceline's old zine as well as a couple of books written by Simon about his time as the Ice King. [Adventure Time #25 and #30]
Note: Penelope makes a cameo in a present day scene during Adventure Time #75, disguised in a trenchcoat. The explanation for this is unknown.
At some time in the future, BMO tells a group of children about the adventures of Finn and Jake. Marceline and Bubblegum listen in on the storytelling, and eventually fly off into the moonlight to find new adventures together.
Dude, I haven't thought about that day in forever! But I'm with the kid. I hate the ending. I think I just hate all endings. I mean, we're basically in an ending right now. Look around! Everything's finished. The story, the day - there's no more potential, no more excitement. Everyone's asleep. Everything's just done.
Marceline [Adventure Time #75]
BMO continues telling his stories for a thousand years to come. He takes the title "King of Ooo" (not to be confused with the other King of Ooo) and moves into a cabin at the top of Mount Cragdor, where he collects trinkets and memorabilia from Finn and Jake's life. People travel to come and listen to his stories, although as he gets older they become less and less reliable.
It belonged to my best friend; Fred! No... not Fred. His name was... Phil!

Time brings many changes to the Land of Ooo.
The original Candy Kingdom has expanded into a vast metropolis, but has since been abandoned. The great tree at its centre, which once sustained Neddy, has withered and died. Most of the candy people appear to be held in stasis on board the Prize Ball Guardian, an immense robotic replacement for the Gumball Guardians who were destroyed during the second coming of GOLB. The Hot Dog Kingdom has grown into a far larger kingdom that it used to be. A character named Pawn Swan roams the land selling his wares, much like Choose Goose did a thousand years before him. [S05E51 Lemonhope Part Two, S06E35 Graybles 1000+, Graybles 1000+ promo art, Steve Wolfhard's Twitter]
Some other characters from the time of the series are known to survive until this time. Ironically, Sweet P (formerly the Lich) grows up to be a great hero and inherits the Night Sword from Finn. The new form of Gunter continues to rule over the north of Ooo fused with Evergreen's crown as the Ice Thing. As previously mentioned, BMO survives thanks to the fact that he's a robot. The original King of Ooo is still alive. [S10E13 Come Along With Me Part 1, S10E16 Come Along With Me Part 4, SDCC 2018: Ble crew zine "Kings of Ooos"]
Other characters do not get the opportunity to live forever. The Jiggler's casket and Mr. Fox's skull are seen in BMO's collection. Finn and Jermaine's gravestones are both seen, although intriguingly there doesn't appear to be one for Jake. It's possible that Jake lives much longer thanks to all the life essence he absorbed from his biological father. A monument to Finn is seen too, as well as a monument to either Jake or Jermaine. Simon is probably dead, given he was turned back into a normal human, although it's possible that Betty's wish to keep him safe extends his lifespan. [S10E13 Come Along With Me Part 1, S10E16 Come Along With Me Part 4]
The Earldom of Lemongrab also remains intact but abandoned. As promised, Lemonhope returns to it a thousand years after departing the Candy Kingdom to explore the world. Despite Finn and Jake's disappearance from the world, Lemonhope meets them while they are travelling through time after escaping the Vanishing Point, and informs them that their legacy has survived. [S05E51 Lemonhope Part Two, Beginning of the End bonus chapter]
Finn and Jake! My peeps from a thousand years ago! Oh, yes. I have wandered ever since the liberation of the Earldom of Lemongrab. There is much wisdom to find out in the world, if one is humble. Alas, I have not visited those lands in many years. But stories of you two have spread far and wide. Legends of your deeds persist, long after you dudes have vanished.
Lemonhope [Beginning of the End bonus chapter]
All five Elementals are confirmed to be present in the intro to the finale. Therefore, Princess Bubblegum or a future reincarnation of her is probably the unknown pink skinned individual seen behind bars in the Ice Thingdom. This means that the unknown individual holding the telescope could be Marceline, which is further evidenced by the symbol on the telescope which somewhat resembles her initials, "MA", and the fact that the individual rides the duck creature previously seen in Marceline's debut episode. Patience St Pim is still frozen in a ball of ice. Slime Princess and Flame Princess have died and been reincarnated into new forms, who are seen fighting each other. Lumpy Space Princess has also died and been reincarnated. [Steve Wolfhard's Tumblr, S01E12 Evicted!, S10E13 Come Along With Me Part 1]
Everything comes and goes, even me. I'm not going to live forever - long, yeah, but definitely nothing compared to your life expectancy.
Bubblegum talking to Marceline [Adventure Time Comics #23: "Forever (Not) Alone"]
The hybrid descendants of Jake and Lady Rainicorn become a dominant race known as "pups" due to how quickly they are able to breed and grow up. They build a city, possibly alongside the humans from the Islands, and reinvent advanced space travel, connecting Earth with other space-capable civilisations including the grey aliens. The pups appear to be ruled by Gibbon, the son of Charlie and one of Jake's grandchildren. Gibbon has obtained one of the jewels from the Ice Thing, which grants him immortality and pink ice powers. Incidentally, it is the same gem as the one which was in Turtle Princess' "wedding ring". In addition, Gibbon learns the power to "extinguish" other pups' powers. Most pups are extinguished of their powers at birth. [S10E13 Come Along With Me Part 1, Steve Wolfhard's Instagram (1, 2, 3, 4, 5)]
Two adventurers travel the Land of Ooo. They are named Shermy and Beth, and they could be future reincarnations of Finn and Jake. They live in Marceline's old cave house, just like how Finn and Jake lived in Marceline's old Tree Fort. Beth is the pup princess, one of the descendants of Jake and Lady Rainicorn. Another of their friends is Princess Zip, a grey alien who wears a crown just like Princess Bubblegum's, although there seem to be several such crowns in the future; BMO alone owns at least four of them. [S10E13 Come Along With Me Part 1]
Beth, whose former full title is Princess Betony Burrito Jakson IV, runs away from her kingdom to avoid having her powers extinguished by Gibbon, and remains a fugitive. This explains why she and Shermy live in Marceline's hidden-away cave, and also explains why a pup is seen spying on their house. [Steve Wolfhard's Instagram (1, 2, 3, 4, 5)]
One day, Shermy and Beth discover a mysterious object scuffed up by the feet of the Prize Ball Guardian. They decide to bring it to the legendary King of Ooo, BMO, at the top of Mount Cragdor, who identifies it as Finn's bionic arm which was bitten off by GOLB a thousand years prior. BMO goes on to tell Shermy and Beth the story of the Great Gum War and the second coming of GOLB. [S10E13 Come Along With Me Part 1]
On a planet far from Earth, a baby alien called Cuber gets lost in a cave and is threatened by a vicious dog-like creature. He is rescued by his sister Tuber. [S06E35 Graybles 1000+]
Note: The Adventure Time Encyclopaedia and the graphic novel Graybles Schmaybles suggest that Cuber was alive during the events of the series. This is probably false.
Some of the past events of Ooo become preserved as short stories known as graybles, which are used by Cuber later in his life for entertainment and utility. [S04E02 Five Short Graybles, S05E03 Five More Short Graybles, S05E24 Another Five More Short Graybles, Finn & Jake Investigations]
After accidentally killing the bride of a space wedding between two pups, Cuber is attacked by several of their vessels. Fearing for his life, he flees from his spaceship in an escape pod and crash lands on the surface of Earth near the former Candy Kingdom. While on the run he accidentally destroys the Prize Ball Guardian which was carrying all the candy people, possibly ending Princess Bubblegum's legacy for good. He steals one of his assailant's ships, and is able to climb back into space and safely return to his own ship, apparently unaware of how much he had just destroyed. [S06E35 Graybles 1000+]
Cuber briefly meets Finn and Jake while they are travelling through time after escaping the Vanishing Point, and recognises them as the protagonists of his graybles. From their perspective, he is the first person they meet. But from a chronological perspective, he is the last. [Beginning of the End bonus chapter]
Note: Even though this arc officially takes place a thousand years in the future, it was intended by the writers to take place ten thousand years in the future to avoid conflicting with the finale's future. It was changed by a revisionist at Cartoon Network, likely due to a misunderstanding about the writers' intentions.
The last time I saw you was like, a thousand years ago. Something like that. I don't know, it's been hard to keep track of time. I always knew it to be the vampire's curse: An endless existence, watching the world as everything you love grows old and withers.
Marceline speaking to Finn and Jake [Season 11 #1]
By this time, Marceline has taken on the title of "Empress" and rules alongside Princess Bubblegum. After BMO breaks down, Bubblegum leaves the castle for a couple of centuries to search for a patch to repair them, leaving Marceline on her own. [Season 11 #4]
Hunson Abadeer, who misses his daughter, sees an opportunity to trick her into returning to the Nightosphere. He believes that if he is able to erase enough of her memories of Ooo, she will eventually have nowhere else to go. So he employs three memory-stealing creatures to disguise themselves as her faithful robotic servants known as "The Three" and begin siphoning off her memories. She forgets about many of her closest friends, most notably Princess Bubblegum, but she still does not wish to return to the Nightosphere. Hunson Abadeer takes more and more drastic action to uncover and remove Marceline's memories, like trying to trigger them via the discovery of old artifacts. Eventually he summons versions of Princess Bubblegum, Marceline, and Simon from the past to see if they uncover more memories. However, the plan backfires and the individuals from the past defeat The Three. [Season 11 #1 to #4]
Princess Bubblegum returns with the patch for BMO, and the others return to the past where they belong. [Season 11 #4]
Hey, elephant. I'm more ancient than you. Someday I will engulf the Solar System. What was and what will be is meaningless. Meanwhile, you should wonder: are you just a two-headed pile of meat on a crash course with a cosmic dump, or do you contain the sole memory of a million dead stars? How do you light a candle without a match?
The Sun talking to APTWE [S06E10 Something Big]
Death once claimed that Simon would continue to exist as the Ice King until this time, but this has since been proven false. [S05E48 Betty, S10E16 Come Along With Me Part 4]
Time is an illusion that helps things make sense
So we are always living in the present tense
It seems unforgiving when a good thing ends
But you and I will always be back then
I may live on Earth, but a part of me will always belong in the Land of Ooo. It's been quite the adventure, and I'm glad to have been a small part of this wonderful story. Thank you for reading.
