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.

Secondly, this timeline contains all the spoilers, up to and including Distant Lands and Fionna & Cake, so make sure you're all caught up before you continue!

Please leave your thoughts and criticisms in the comments section at the bottom of the page. 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.

Enjoy!

Special thanks

This piece was inspired by several Adventure Time timelines published before it, which I wanted to expand upon. The timeline by RedLionKing, which unfortunately seems to have been deleted from Imgur, inspired the prosaic presentation style of my version, and this concise timeline by Viernes de Siluetas was the origin of the date system I chose to use.

Various other members of the fandom have inspired my own interest in digging deep into the lore of this show. Thanks to Uncivilized Elk, the Bacon Pancast, all the nerds on the various Adventure Time Discord servers I've been a part of, and all the editors and transcribers on the Adventure Time fan wiki without whom this task would have been a lot more arduous.

An outdated Korean translation of the website by SpiderCider and Décadent is available here 🇰🇷. If anyone is interested in providing up-to-date translations for any language, send 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.

Sources

Adventure Time is a large franchise, and as a result it has spawned a lot of spin-off media, such as comics, graphic novels, and video games. However, a lot of this officially licensed material is written without the creative input of the show's crew, so is usually considered non-canon.

There is no official definition of canon, but for the sake of simplicity a piece of media must meet the following criteria to be considered canon on this site:

1. It must not significantly contradict another piece of canon media.
2. It must have significant creative input from a member of the Adventure Time cast or crew.
3. It must be officially endorsed by Cartoon Network.
4. It must not be a crossover with another piece of media.

Non-canon information is hidden by default. If you would like to see non-canon information, use the checkbox at the top of the page. Non-canon information will be clearly highlighted using pink boxes.

See the media page for the full list of all canon and non-canon media considered for this timeline. Whenever I make a statement or pull a quote from somewhere, I will show the source in [square brackets.]

Date system

All dates are organised around a year zero, which is the year of the detonation of the Mushroom Bomb and the impact of the war-time Catalyst Comet. BMB stands for Before Mushroom Bomb and AMB stands for After Mushroom Bomb. 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 sections with an equivalent 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 detonation of the Mushroom Bomb and the impact of the war-time Catalyst Comet happen 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 exactly 0 AMB.

And now, without further ado, let's begin...

THE PAST

This section covers the past, spanning the time from the beginning of existence up to 996 AMB.

The Beginning of the Multiverse

In the very beginning, reality exists as a chaotic sea of monsters. Beings such as Orgalorg, Coconteppi, and The Lich reside in this writhing mass. By incomprehensible chance, the monsters eventually come to a common agreement on the state of reality, and this consensus becomes the Multiverse. According to an ancient tome called the Enchiridion, the Multiverse is therefore 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. [Gold Stars, The Enchiridion & Marcy's Super Secret Scrapbook, Together Again, Wizard City]

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. [Gold Stars]

The Structure of Existence

The Multiverse imagined by the primordial monsters is composed of a large number of dimensions. One of these dimensions contains the planet Earth (sometimes referred to as "Third Orb") as well as all the other planets, stars, and galaxies in our own universe. The Multiverse grows over time as new alternate timelines are created by divergent events. It's not clear if every dimension is an alternate timeline of one original universe, or if realms like the Nightosphere and Lumpy Space were completely separate from the beginning. Amidst this complex system of dimensions is the Time Room. [The Enchiridion & Marcy's Super Secret Scrapbook, Prismo the Wishmaster, Return to the Nightosphere, Trouble in Lumpy Space]

The Time Waves that emanate from the Time Room are produced in the Time Core, which contains two unnamed deities striking each other over and over for all eternity. [Prismo the Wishmaster]

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. [The Enchiridion & Marcy's Super Secret Scrapbook]

A very rudimentary form of temporal synchronisation is demonstrated by Finn the Human when he interacts with the little people, who reside in "a different dimensional plane" according to Jake the Dog. Finn shakes the little people, which synchronises their frequencies enough to allow for brief interdimensional communication. [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 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 over time, causing there to be periods during which magic is stronger or weaker than usual. [The Enchiridion & Marcy's Super Secret Scrapbook, Ocarina, 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. [The Enchiridion & Marcy's Super Secret Scrapbook]

non-canon information
According to one account, there is a place at the very beginning of time called the Vanishing Point. 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. [Beginning of the End #1 and #3]

The Cosmic Entities

Prismo, who was briefly mentioned earlier, is one of the many god-like "cosmic entities" who make up the pantheon of the Multiverse. Most of them have a specific purpose within the elaborate clockwork of existence.

Prismo is a wishmaster and the keeper of the Time Room and the Time Core, capable of granting one wish to anyone who succeeds in visiting him. He takes the form of a friendly pink two-dimensional projection of a human figure. He is kept alive by the dreams of an old man who sleeps in the floating ruins beyond the Time Room. When a visitor makes a wish, the wish can sometimes spawn a wish-altered reality which becomes a new dimension of the Multiverse, while the visitor's original dimension is left untouched. This is one way in which divergent events can create new branches of the Multiverse. Prismo is responsible for maintaining order across these dimensions by preventing harmful crossovers. [Finn the Human, Wake Up, Crossover, Prismo the Wishmaster]

Prismo is subject to a regular audit from a being named Scarab, to make sure he is not endangering the structure of reality by abusing his wish-granting powers. Scarab covets Prismo's job. Scarab's supervisor is another cosmic entity named Orbo. All of them are on the payroll of their mysterious Boss. [Prismo the Wishmaster, Jerry]

The Cosmic Owl is in charge of monitoring the dreams of every being in the Multiverse and chooses which ones will come true. Dreams containing the Cosmic Owl are therefore invariably prophetic, although these dreams are often metaphorical rather than literal. Dreams containing the Cosmic Owl in which the dreamer sees their own death are known as "croak dreams", and will accurately predict the death of the dreamer. The Cosmic Owl lives in a motel made of stars, and often visits the Time Room for game nights with Prismo. The fact that Prismo is the manifestation of a dream possibly hints at a deeper connection between Prismo and the Cosmic Owl. [The New Frontier, Jake the Dog, Hoots]

Life and Death are the two cosmic entities in charge of determining what happens to the souls of those who have passed away. They are in a romantic relationship. [Together Again, The Gift That Reaps Giving]

The Catalyst Comet is a cosmic entity that operates on a millennium-long cycle. [Astral Plane]

Every comet strike brings great change to Earth 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. The Agents of Change are reincarnated after death so that they can continue their mission over the course of more than one lifetime. The Comet takes on a different colour every time it strikes. Four have been depicted: Green, Yellow, Blue, and Purple. The agents that they spawn will go on to become some of the most influential beings in history. [Evergreen, Orgalorg, The Comet]

GOLB is the cosmic entity embodying chaos and discord, taking the form of an immense red infantile creature with a pyramid-topped head. When he consumes people, they are reset to their primal state and eventually removed from existence in such a way that not even the most powerful magic can bring them back. [You Forgot Your Floaties, Come Along With Me]

Many of the other monsters from before time likely exist as cosmic entities, including Orgalorg. In one ancient book, another monstrous deity named Malus is seen alongside GOLB. [Gold Stars, Come Along With Me]

Some other characters are depicted as god-like but appear to live in singular dimensions alongside mortal peers. Examples of such beings include Abraham Lincoln, Party God, and Grob Gob Glob Grod. [Sons of Mars, The Party's Over Isla de Señorita]

The Concept of Death

All the mortal beings in the Multiverse will eventually die. However, death is not necessarily the end. After the mortal body has perished, the soul can continue without it. [Together Again]

When a being dies, they are first transported to the Land of the Dead, which is like a gateway and a hub leading to all the other deadworlds, of which there are fifty in total. In the afterlife, souls can take the form of any of their past forms, including any of their previous incarnations at any age. Newcomers are assigned to a deadworld based on the way they lived their lives, with higher deadworlds generally being more desirable than lower ones. There is much variety among the fifty deadworlds. The First Deadworld is a miserable place where souls are left to dissolve away until they become little more than a part of the landscape. At the other end of the spectrum, the Fiftieth Deadworld is a realm whose inhabitants have achieved escape from all desire, and exist for all eternity in total contentedness. Notably, both fates have the same outcome in the end, which is the loss of individuality. Unlike in many other depictions of the afterlife, a soul's judgement is not final, and souls can move between deadworlds if they change. [Death in Bloom, The New Frontier, Together Again]

The Land of the Dead and all the deadworlds are governed by Death himself, who lives in a castle of light and administrates with the help of his "undertakers"; souls who have chosen to assist Death and been turned into angels. The position of Death is not permanently fixed to one person, since Death can be killed. But to kill Death is to become Death, shackled to all the associated responsibilities of the position. [Together Again]

Deceased souls can also be granted another option for their continued existence: reincarnation. In charge of reincarnation is the snake-headed deity named Life. When a soul makes its way to her realm, she shapes them a new body on her pottery wheel and sends them back to be reborn anew. Reincarnated souls generally do not retain their memories, but they can maintain a tenuous cosmic connection with their past selves. Souls will normally become living biological beings when they reincarnate, but this is not always the case. [Together Again, The Vault, Jelly Beans Have Power]

According to Mr. Fox, there might be a limit on how many times a single soul can reincarnate, since there are only so many lives to share out between all the souls. [Together Again]

Dead souls can manifest in the living world as ghosts whenever required. Souls will often visit the mortal plane if they still have "unfinished business" to attend to, since they will only be able to ascend to a higher deadworld once their business is complete. Sometimes a soul will forget the details of their mortal life, and in order to ascend they must haunt the mortal plane as a ghost to find key information about themselves, such as their cause of death. [Together Again, Ghost Fly, Ghost Princess]

Conversely, there are ways for living beings to temporarily achieve some of the effects of being dead. For example, it is possible to temporarily become a ghost by stopping and then restarting one's heart. It is also possible to visit the Land of the Dead via a ritual that involves crossing one's eyes and walking through the corner of two walls, but getting to any of the fifty deadworlds is much more difficult to achieve without actually dying. [Ghost Fly, Death in Bloom]

Deceased souls can actually "die" a second time if they are killed within one of the deadworlds or while visiting the realm of the living as a ghost. The fate of these souls is not known. [Together Again, Ghost Fly]

non-canon information
According to one account, deceased souls have the option to take physical form as a demon and go to live in the hellish Nightosphere. [Adventure Time #53]

The Concept of Magic

According to the Enchiridion, 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. [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 the Human has performed magic via meditation and song, and Son of Rap Bear can produce explosions by rapping. [The Enchiridion & Marcy's Super Secret Scrapbook, Still, The Comet, 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. [You Forgot Your Floaties]

There are two perspectives on the concept of magic. Scientists like Princess Bubblegum believe that it exists due to observational quantum effects and is grounded in scientific principles. This does not mean that scientists do not believe in magic; to not believe in magic in a world where it is so obviously abundant would be foolish. Rather, they simply disagree with the idea of calling it magic, since this makes is sound like it is independent from science. This is somewhat justified, since the mystification of magic can often lead to confusion between real magic and exploitative nonsense, especially in gullible people. On the other end of the spectrum, most magicians choose to accept the hand-wavy imagination theory given in books like the Enchiridion, and question it no further than that. Thanks to this blind belief, they are generally far more proficient at performing magic. Neither view is incorrect. [Wizards Only Fools]

Life on Earth

The planets Earth and Mars form around a sentient star called the Sun. Around a billion years later, life begins to emerge on Earth. [Something Big]

A demon named Hunson Abadeer comes into being around this time, and becomes ruler of the Nightosphere, a fiery and hellish dimension. He constructs or obtains the Abadeer Axe. [It Came from the Nightosphere, Return to the Nightosphere]

On Planet Earth exists the concept of five fundamental elements: fire, ice, candy, slime, and lumps (parodying the real-life classical elements of fire, water, earth, air, and aether). Despite the existence of five elements, lumps is less well known and as a result many accounts describe only the first four. [Elemental, Skyhooks II]

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. Like other beings who reincarnate, the Elementals can occasionally make contact with their past lives. [Evergreen, 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, and can also undo some other types of transfiguration magic. The element is associated with a dimension called Lumpy Space. People from Lumpy Space have been seen far from Planet Earth, suggesting that Lumpy Space is accessible from anywhere in the universe, and perhaps from anywhere in the Multiverse. Furthermore, lumps apparently permeates through the universe, similar to aether, its classical counterpart. [On The Lam, Skyhooks II]

Like all magic users, the power of the Elementals is entirely dependent on the elasticity of Earth's 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. [Evergreen, Elemental]

The symbol used to represent the main four elements is a circle divided into quarters. [Jelly Beans Have Power]

65 million years ago

Evergreen's Crown

During the time of the dinosaurs, the four Elementals are Urgence Evergreen (ice), Balthus (fire), Chatsberry (candy) and Slimy D (slime). They each rule their respective elemental realm. The Lumps Elemental of this time is never mentioned. Urgence Evergreen the Ice Elemental has a mutated dinosaur servant named Gunther, who vainly hopes to eventually become his master's magical apprentice. [Evergreen]

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 realms. They reject his plan, stating that wish magic is too dangerous and reminding him that even if they die, they will be reincarnated. [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, he is tracked by the blind and enraged Magwood, and just as Evergreen is about to use the completed crown to vanquish the Comet, the lava dog attacks his castle. Evergreen becomes trapped under debris during the following battle and is unable to put on the crown and wish for the Comet's destruction, so instead he orders his dinosaur servant Gunther to do it. But Gunther's greatest desire is not to destroy the Comet. [Evergreen]

Gunther's wish becomes permanently associated with the crown, and its wish-granting abilities are disabled. In the future, any individual who wears the crown will become its "host" and turn into Gunther's image of Evergreen: a cruel, mad, and powerful ice elemental. [Holly Jolly Secrets Part II]

The Green Catalyst Comet kills the four Elementals, and is likely to be the event which causes the extinction of the dinosaurs. Gunther is "saved" by the crown; a copy of his original consciousness is held within its complex circuitry. Any future hosts of the crown will be similarly "saved". [Evergreen, Broke His Crown]

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 claims to be "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. [Finn the Human, Whispers]

Millions of years ago

Wizards of Prehistory

The magic users of the prehistoric world establish a secretive settlement named Wizard City. Its rulers are a cult of dark magicians who worship and draw their power from the primordial monster known as Coconteppi; a being who has existed since before time itself. But upon Coconteppi's death the dark magicians are usurped by a new regime who oppose dark magic. Knowing that Death may not be able to contain Coconteppi for good, the new rulers seal away his body in a giant tomb and bury it in a secret location deep beneath the city. [Wizard City, Gold Stars]

This age of wizardry likely saw the creation of The Enchiridion. This ancient tome, which has already been mentioned a few times, is one of the most powerful magical artifacts in the Multiverse. Its exact origin is unknown. Due to its contradictory nature, it may not even have a true origin. 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 prophetic knowledge from the 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]

According to one iteration of one copy of the Enchiridion, every ten thousand years it 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. [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 of Power" 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. [The Lich, Skyhooks II]

Eventually, Earth's elasticity and magical potency begins to subside, giving way to a less magically active world. It's possible that Coconteppi's death contributed to this decline, since the dark magicians were using him as a source of power, but this is only speculation. [Elemental, Wizard City]

Hundreds of thousands of years ago

Humans and Vampires

The extinction of the dinosaurs allows mammals to dominate the planet, and eventually this leads to the evolution of vampires and humans. According to Hunson Abadeer, vampires exist before the emergence of humans but go into hiding during the Ice Age. [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 reproduce by turning their victims into more vampires. However, vampires do not actually feed on blood itself, instead taking their sustenance from the colour red. Most vampires feed on blood anyway, preferring the taste. They remain hidden from the human population for most of human history, only appearing in folklore and fictional stories like Dracula. [Evicted!, Vamps About, Fionna and Cake and Fionna]

Werewolves also seem to be native to Earth, so probably evolved at around this time. Like vampires, they remain hidden from the humans. [The Enchiridion & Marcy's Super Secret Scrapbook]

Life on Mars

Earth is not the only place in the Solar System harbouring life. Long ago, a self-proclaimed utopian society emerges on Mars, consisting of the green-skinned Martian race. It is not clear where they came from, although they have several strong connections with the human race. Their king is Abraham Lincoln, a human from the future, who was presumably somehow transported back in time to become the ruler of Mars. Lincoln's champion is the four-faced Grob Gob Glob Grod, who later becomes entwined in the religious beliefs of the inhabitants of Earth. Grob Gob Glob Grod has a brother named Magic Man, and Magic Man has a wife named Margles. [Sons of Mars]

note
Grob Gob Glob Grod's name is often shortened to "Glob". For simplicity, this website will refer to him as Glob most of the time. Additionally, it is worth clarifying that Glob and GOLB are two completely separate entities and should not be confused.

A human roboticist from the future named Moseph Mastro Giovanni is involved in the design of the Martian colony, as seen in blueprints on his desk, and the human magician Betty Grof claims that Glob's helmet will react to her "ancient human DNA code", further suggesting at an anachronistic connection between humans and Martians. [You Forgot Your Floaties, The More You Moe The Moe You Know]

non-canon information
According to one account, there was a period of conflict on Mars known as the Martian Independence Era, suggesting that the Martian society emerged following some kind of war of secession. [Marcy & Simon #5]

Mars is attacked by GOLB, the ancient Cosmic Entity embodying chaos, during an event known as the First Coming of GOLB. The entity consumes Margles, the wife of Glob's brother Magic Man, and completely removes her from existence. To prevent GOLB's 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 the tallest mountain on Mars, Olympus Mons. [You Forgot Your Floaties]

Glob worries that Magic Man's grief over the loss of his wife has corrupted his spell programming. Unfortunately, this turns out to be correct, and the new defence system goes insane and has to be deactivated. Magic Man begins to spiral into madness after symbolically losing his wife for a second time. His madness turns to unrelenting cruelty. He uses his magic to become an evil trickster and torments the people of Mars for centuries to come, for nothing more than his own entertainment. [Sons of Mars, You Forgot Your Floaties]

At least a thousand years before 0 AMB, the Yellow Catalyst Comet begins to approach Earth. Orgalorg, one of the monsters from before time, plans to intercept it and absorb its power. Abraham Lincoln sends Glob to vanquish Orgalorg and end his reign of terror. [Orgalorg]

The "inhospitable planet" spoken of by the alien elders is actually Earth. Orgalorg is compressed into the form of an immortal penguin, his memories and identity suppressed into the deepest depths of his mind. He becomes a hunter-gatherer alongside early humans. [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.

non-canon information
Finn and Jake witness both the installation of M.A.R.G.L.E.S. and the battle between Orgalorg and Glob while they are travelling through time after escaping the Vanishing Point. [Beginning of the End bonus chapter]

note
Glob still had his hair during the First Coming of GOLB, but during his battle against Orgalorg he is wearing his headgear. Since Glob wears his headgear to hide his baldness, this suggests that the arrival of the Yellow Catalyst Comet came after the First Coming of GOLB. However, this is not confirmed; the arrival of the Yellow Comet could have come first.

At some point, Abraham Lincoln meets Hunson Abadeer. [Return to the Nightosphere]

Other Worlds

Aside from Earth and Mars, a multitude of other planets in and around the Solar System become inhabited during the universe's long history. Eventually, interstellar travel becomes widespread enough that many of the galaxy's species are able to visit one another, forming the backbone of an interstellar community. As far as we know, the humans on Earth never achieve contact with their alien neighbours. [On The Lam]

The structure of the Solar System in Adventure Time's reality has a few differences compared to its structure in real life. Mars has a large purple moon, there is an unnamed red planet with a ring system, and there is an object resembling a black hole. No other real life planets have ever been seen or mentioned. Models and drawings of a planetary system have been seen, but they are completely unrecognisable. [BMO, The New Frontier]

The home planet of the siblings Cuber and Tuber appears to be a fairly Earth-like world. Their people invent the "graybles"; short thematically-linked stories depicting historical scenes, used to teach morals and practical skills or simply for entertainment. [Graybles 1000+]

Many of the planets once terrorised by Orgalorg before his defeat at the hands of Glob are home to a range of unique lifeforms. [Orgalorg]

The planet of the koala people appears to be a desert world where food and water is scarce but gold is plentiful. The planet falls under the oppressive regime of a group of greedy humanoid lizards, leading to the emergence of a group of koala rebels who have been fighting for their freedom ever since. Many other alien species are also present on this planet. [On The Lam]

The home planet of the greys is abandoned by its native inhabitants at some point. Some of the greys will eventually settle on Earth. A round trip from Earth to this planet and then back takes at least forty years. [High Strangeness, Come Along With Me]

The Drift is an ancient space station inhabited by many different species, including shell people, bunny people, and members of Cuber's species. The station is comprised of various pods, which each contain a certain biome suited to a specific set of species. [BMO]

Nerraw is a small world orbited by an even smaller black hole. It is inhabited by a powerful shape-shifter named Warren Ampersand, who wishes to be immortal. He creates a plan to drain the youth from his own children so that he can live forever. Every generation, he impregnates a chosen host so that their offspring inherit his powers. Later in his children's lives, he lures them to Nerraw where he tricks them into shape-shifting while wearing a special belt which drains their power and gives it to him. Warren uses his shape-shifting powers to fabricate an entire society and culture for Nerraw, as part of the deception. [Jake the Starchild]

He continues this sick trickery for many generations, exploiting and then outliving each child in succession. One of his future sons will be Jake the Dog. [Jake the Starchild]

A collection of asteroids are inhabited by two species named the leaflan and the tuffbones. The asteroids appear to be part of Earth's solar system because Princess Bubblegum can see them through a telescope and reach them using a conventional rocket from Earth. [Marceline Gone Adrift #2]

The Rainicorn-Dog Wars

A dimension called 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 unknown reasons, the two species become each other's enemies, eventually leading to the outbreak of the millennia-long Rainicorn-Dog Wars. 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. [Her Parents]

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.

non-canon information
Finn and Jake briefly witness a battle from the Rainicorn-Dog Wars while travelling through time after escaping the Vanishing Point. The dogs are seen to battle using ray guns, while the rainicorns attack using energy blasts from their horns. [Beginning of the End bonus chapter]

All of rainicorn history is documented in a huge book called the Rainicornicopia. [Paper Pete]

The penguin form of Orgalorg appears in some hieroglyphic artwork from the time of the Ancient Egyptians, implying that he joined their society. The Egyptians construct the pyramids. As humans continue to develop and thrive, the elasticity of the Earth's dimension settles into a more rigid pattern, bringing about the end of magic. For now. [Orgalorg, Daddy-Daughter Card Wars, The Enchiridion & Marcy's Super Secret Scrapbook]

non-canon information
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. [Orgalorg]

The legend of the Dual Swords takes place during the time of the Ancient Romans:

Thousands of years later, the Dual Swords will end up back together in the arena of the Fight King, who is likely an immortalised version of the evil emperor. [Morituri Te Salutamus]

During the middle ages, Orgalorg joins some kind of hooded organisation: possibly a monastery or a secret society. During the renaissance, he appears alongside European nobility. [Orgalorg]

The Crown's Journey

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. [Broke His Crown]

Likewise, the consciousness of an Icelandic boy named Sveinn becomes stored in the crown's circuitry after wearing it just once. 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. [Broke His Crown]

The crown remains in Northern Europe, and by around 20 BMB it has come into the possession of an unidentified Scandinavian dockworker. [Holly Jolly Secrets Part II]

Abraham Lincoln

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. On Mars, Abraham Lincoln is prophesied to someday meet Jake the Dog. [Sons of Mars]

c. 100 BMB to 0 AMB / 1910 CE to 2010 CE

The Modern World

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 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. [Orgalorg]

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. [Orgalorg]

Shortly before 0 AMB, a Mars rover (resembling the real life Mars rovers Opportunity and Spirit) discovers evidence of the Martian civilisation. It's possible that humanity was on the brink of making contact with Mars at this time. [Sons of Mars title card]

45 BMB to 0 AMB / 1965 CE to 2010 CE

Simon and Betty

In the Earth's dimension, 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 significant number of humans still believe it is real. [Holly Jolly Secrets Part II]

A human named Simon Petrikov is born in 45 BMB (1965 CE). Another human named Betty Grof is born around the same time. [Simon & Marcy]

non-canon information
According to one account, Simon is raised by his unnamed mother. [Adventure Time Comics #16: "Broken"]

Simon attends the University of Petrograd in Russia and earns his PhD, becoming an antiquarian. He moves to Seattle and begins delivering lectures at the University of Washington on the artifacts he is searching for, including the Armor of Zeldron, the Wand of Dispersement, The Enchiridion, and Evergreen's Crown. His lectures are often met with ridicule for his fanciful assertions about these items' magical properties. But Betty, by this time a post-grad student, becomes absolutely engrossed in them. [The Enchiridion & Marcy's Super Secret Scrapbook, Jerry]

Betty had been due to leave on a six month trip to study petroglyphs in the Australian Outback, but instead she cancels her plans and accompanies her beloved Doctor Petrikov on a trip to Pakistan to search for the Enchiridion. The trip is successful. After returning home, Simon presents his findings at the Museum of History. Betty tells him she would prefer him to take the credit for the discovery, and hangs back rather than engaging with the press. A journalist named Bruce Guese writes a newspaper article about the book's discovery, and Simon keeps the clipping. [Temple of Mars, Jerry, The Enchiridion & Marcy's Super Secret Scrapbook, I Remember You]

Betty's infatuation with Simon grows far beyond an admiration for his work. Simon initially thinks he should keep their relationship strictly professional, and Betty re-books her six month Australia trip. But at the eleventh hour, Simon catches her at the bus stop and tells her that he reciprocates her feelings. They are both delighted, but Simon fails to consider how much Betty is sacrificing by cancelling her trip for a second time just to spend more time with him. This will become a trend in their relationship; Betty's dreams will be voluntarily pushed to one side in favour of pursuing Simon's goals. [Jerry, Cheers]

Betty eventually becomes Simon's fiancée and they co-author a book called Mystic Rituals and their Space Time Applications. This book contains numerous rituals taken from ancient records, from before the disappearance of magic. These rituals include instructions for entering the Nightosphere and instructions for opening a portal through time, although they cannot be performed in the present day and Simon remains sceptical that they were ever real. [Betty, The Enchiridion & Marcy's Super Secret Scrapbook]

During an expedition in Java to search for a lost temple, Simon and Betty get caught in a flash flood that washes away half their supplies, but Betty is so skilled at surviving in the wilderness that she scrounges up a "four star meal" anyway. [Simon Petrikov]

Simon's research into the arcane also 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. [Come Along With Me]

Simon's next archaeological trip would prove to be his last. He travels to Scandinavia in search of Evergreen's Crown, and manages to purchase it from a dockworker in Northern Scandinavia, before excitedly bringing it home to show Betty. Not knowing its true power, he places 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, to be like his cruel master Evergreen. Simon becomes a host of the crown, and his transformation into a mad ice wizard begins. [Holly Jolly Secrets Part II, Evergreen]

He chases the terrified 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. [Betty]

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. [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. [Broke His Crown]

5 BMB to 0 AMB / 2005 CE to 2010 CE

Marceline Abadeer

Marceline Abadeer is a half-demon half-human hybrid, born in 5 BMB (2005 CE). Her father is none other than Hunson Abadeer, the demonic ruler of the Nightosphere, and her mother is a human named Elise. It is not known how this unlikely relationship arose. [Everything Stays, Obsidian]

Marceline is raised by her mother on Earth. Marceline retains very little memory of the first five years of her life. She and her mother live in a mobile home, and at some point they go on a trip to the beach. Marceline keeps photographs from this trip on a USB drive, but the drive gets corrupted and over time she forgets what was on it. [Everything Stays, Ketchup]

It is not clear exactly how involved Hunson is in his daughter's childhood. In her scrapbook, Marceline says that she didn't know anything about him until they met later in her life, but pictures of her as a child can be seen in his castle in the Nightosphere, suggesting her parents maintain some form of contact. Elise tells Marceline they ran away from Hunson because he was scary, while Hunson claims he had to leave for business in the Nightosphere. [Return to the Nightosphere, The Enchiridion & Marcy's Super Secret Scrapbook, Obsidian]

non-canon information
Some accounts suggest that Marceline grew up with her father and was a vampire from birth. This is false. [The Adventure Time Encyclopaedia, Seeing Red]

One of the few things that Marceline does remember from her early childhood is the theme song for a soda company called "Super Porp", who produce a fizzy grape drink. [Dark Purple]

28 BMB to 0 AMB / 1982 CE to 2010 CE

Prelude to the War

At some point before 2 BMB (2008 CE), a roboticist named Moseph Mastro Giovanni, or just "Moe" for short, establishes a company called MO Co. They produce a wide range of robots for various purposes. As Moe ages, he begins to replace parts of himself with cybernetics to extend his life, becoming a cyborg. Another roboticist named Hugo is a contemporary of Moe. His robots have been described as "janky off-brand cousins" of MO Co models. [Be More, BMO]

After the death of an unknown previous Elemental, the Ice Elemental is reborn as an individual named Patience St Pim in 28 BMB (1982 CE). She and the other Elementals of the modern generation discover their powers and eventually find one another, although their powers are very weak due to the rigidity of the Earth's dimension at this time. [Elemental]

The Elementals meet up every once in a while for coffee. Despite the weakness of their magic, they begin to see visions of an impending cataclysm. Like Evergreen millions of years before her, Patience St Pim seeks a way to survive it, but the other Elementals disagree. Ignoring their objections, she freezes herself underwater and waits out the approaching disaster. [Elemental]

Shortly after this, the rest of the world begins to realise that war is on its way. At some point, Simon moves to the United States. He mentions that an "international crisis" is developing in some of his notes in the Enchiridion. The next day, he sends the Enchiridion to the Scandinavian Institute of Technology Museum. [The Enchiridion & Marcy's Super Secret Scrapbook]

0 AMB / 2010 CE

The Great Mushroom War

After a quick escalation, the world erupts into global war.

The Great Mushroom War earns its name from the mushroom clouds produced by the nuclear bombs, which reduce most of human civilisation to ashes. One of the biggest is the "Mushroom Bomb", which is powered by something else besides its nuclear payload. It tears at the fabric of reality and massively increases the Earth's dimension's elasticity, delivering magic back into the world. It's possible that the whole thing is orchestrated by The Lich, since the bomb releases his spirit and allows him to rise from his dormancy. During the war, some kind of energy weapon rips a huge chunk from the face of the Earth, leaving a crater about the size of the Moon. [Finn the Human, Crossover, BMO]

Despite the near extinction of the human race, there are several survivors.

• The antiquarian Simon Petrikov is protected by Evergreen's Crown. [The Enchiridion & Marcy's Super Secret Scrapbook]
• Marceline Abadeer and her mother Elise both survive somehow. [Obsidian]
• Moseph "Moe" Mastro Giovanni, the owner of the robotics company MO Co, survives thanks to his mostly cybernetic body. [Be More]
• The Ice Elemental Patience St Pim survives because she is frozen deep underwater, although the other Elementals perish. [Elemental]
• The antiquarian Betty Grof has escaped through a portal to 999 AMB, skipping the war. [Betty]
• Many native werewolves and vampires survive. [The Enchiridion & Marcy's Super Secret Scrapbook]
• The penguin form of Orgalorg survives thanks to his true nature as a cosmic entity. [Orgalorg]
• A group of humans led by Hugo, along with his robotic companion CGO, escape into space on a rocket ship. [BMO]
• Many humans survive for a while. These are presumably those who were far enough away from the initial blasts and managed to avoid the worst of the radiation. Some of them make it to large bunkers. [Islands graphic novel, Everything Stays, 2015 Spoooktacular, Obsidian]

Something goes wrong with Hugo's rocket ship, but they are rescued by a passing group of greys. To survive in space, Hugo uses "bio-hacking" to merge the DNA of the greys with that of the human escapees, creating a new race of ageless human hybrids: the grey elves. The process proves fatal to the greys who participate. With the greys' spacecraft failing, the grey elves are rescued for the second time by a service droid from the Drift, the mysterious ancient space station which is home to many different species. Hugo establishes himself as a chief scientist and corporate leader on board the Drift. [BMO]

Due to the increased elasticity of the Earth's dimension and the reintroduction of magic following the detonation of the Mushroom Bomb, the world begins to change very rapidly. Hybrid creatures and strange mutant animals begin to emerge, and a variety of extra-dimensional creatures begin to flood in through 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. [The Enchiridion & Marcy's Super Secret Scrapbook, Obsidian, Her Parents, Lady Rainicorn of the Crystal Dimension]

A group of vampires known as the Vampire Court comes out of hiding and also begins hunting humans. The court consists of the Vampire King and his four powerful underlings, each of whom are named after a card in the Major Arcana of a tarot deck: the Fool, the Empress, the Moon, and the Hierophant. Many survivors are turned into mindless vampire minions who serve the higher members of the court. [Everything Stays, Vamps About]

On top of all this, many humans become mutated by a mixture of radiation and magic, creating a race of mindless zombies which will later become known as oozers. Some zombified businessmen become preserved in an iceberg. [Business Time, Simon & Marcy]

Remarkably, some companies continue to operate following the end of the world. The Super Porp soda company has fully automated staff recruitment and customer delivery systems, so production and commerce continues as before, with various non-humans taking the place of the dead human employees. MO Co also persists into the post-apocalyptic world thanks to automation and the survival of its owner, although the factory floor is eventually shut down. A company that produces a weekly magazine named "Ble" may have originated from before the war. Production mysteriously ceases some time before 500 AMB, leaving the employees' skeletons to gather dust at their desks. A Pudding Troll is hired in about 500 AMB to guard the offices, even though there is nothing left to protect. [Dark Purple, Be More, Blenanas]

Some of the movies, books, television shows, and music from before the Great Mushroom War will manage to survive into the post-apocalyptic world. [The Eyes, Go With Me, Video Makers, Heat Signature, BMO Noire, Simon & Marcy, Another Five More Short Graybles, Bad Timing, Mama Said, Everything Stays, The Music Hole, Hero Heart, BMO]

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 the Human. [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" in the above quote, perhaps implying that it has been less than a millennium since his Comet's arrival.

---

0 AMB / 2010 CE

In the Aftermath

The humans who survived the Mushroom War persist for a while in a post-apocalyptic society, travelling the wasteland and trading meat and fuel. Elise is one such human. She and her daughter Marceline continue living in the mobile home, which has broken down in the middle of the wasteland. Elise knows about a bunker where they might find other human survivors, so she and Marceline begin to prepare for the journey across the desert to reach it. This is despite the fact Elise is slowly succumbing to a deadly disease, or perhaps radiation sickness. Elise tries to keep the true gravity of the situation a secret from Marceline, who is only five to seven years old at this time. [Obsidian, Simon & Marcy]

During an encounter with a mutant wolf, Marceline is forced to use a demonic power she has inherited from her father; the ability to steal souls. She takes the soul of the wolf. Not long after this encounter, Elise begins coughing up blood and realises she can't fight off her sickness much longer, so she tricks Marceline into travelling ahead of her and tells her that she would catch up later. She records a voice message for Marceline apologising for lying to her, and sends it to the bunker for Marceline to listen to when she arrives. Then finally, she passes away. [Obsidian]

Marceline manages to reach the bunker on her own, but its only inhabitants are the corpses of its former denizens. She never receives the message from her mother because the answer machine is too high on the wall for her to reach. For a long time, she doesn't understand what happened to her mother, and believes that she ran away from her because of the encounter with the wolf. [Obsidian]

She eventually comes to realise it was sickness which took her mother away, but the trauma of being abandoned stays with her, and she doesn't end up hearing Elise's message until over a thousand years later. [Obsidian]

2 AMB / 2012 CE

The Wreckage of the World

While exploring the ruins of a city on the West Coast of what used to be the United States, Simon Petrikov comes across Marceline Abadeer, who is still on her own. Simon is quite far into his transformation into an Ice Elemental by this point, with blue skin and lengthening white hair. Simon takes Marceline into his care and learns the name of her mysterious father, Hunson Abadeer. He gives Marceline a teddy bear from the smashed display of a nearby toy store, which she names Hambo. It becomes one of her most treasured possessions. Marceline is seven years old at this point and Simon is forty-seven. [The Enchiridion & Marcy's Super Secret Scrapbook, Memory of a Memory, I Remember You, Sky Witch, Simon & Marcy]

note
According to The Enchiridion & Marcy's Super Secret Scrapbook, Simon learns about Hunson from a note left by Elise. However, Obsidian contradicts this slightly since there was no mention of any note when Elise abandoned Marceline.

In an alternate universe, Simon is killed by vampires before he meets Marceline. Marceline is instead taken under the care of the Vampire King and his court. She becomes its sixth and most powerful member, and takes the name "The Star" from the Major Arcana. But none of this transpires in the timeline that we are concerned with. [The Star]

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. He also mentions that the sky lit up again, which could be a reference to the arrival of the Blue Catalyst Comet. At one point, Marceline is seen clutching Hambo and watching a city burn to the ground. [Friends Forever, Come Along With Me]

Some survivors set up a refugee camp in an underground mall, and Simon and Marceline visit it from time to time. [The Enchiridion & Marcy's Super Secret Scrapbook]

note
Simon implies that Marceline is the first person he found, but his diary from Friends Forever and the fact that he knew about the refugee camp in the mall suggest that he met other survivors.

At some point, some wizards steal the Enchiridion from the Scandinavian Institute of Technology and bring it back to America. [The Enchiridion & Marcy's Super Secret Scrapbook]

Simon and Marceline begin 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 practise kung fu using books they find, as a way to combat anything that might try to harm them. 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 have their first encounter with undead creatures while looting an abandoned store, and Marceline names them "oozers" because of the thick green liquid that oozes from their orifices. 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. This happens a few times, but with Marceline's help he is sometimes able to resist the urge to resort to the crown's power. [Simon & Marcy, The Enchiridion & Marcy's Super Secret Scrapbook, Simon Petrikov]

note
"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 making her believe that the medicine was actually chicken soup.

At around the same time, a strange pink substance begins materialising across the ruins. This substance is a collective consciousness called the Mother Gum. It is not known whether the Mother Gum formed on Earth or came from a different dimension, but it begins assisting Simon and Marceline. [Simon & Marcy, Bonnie and Neddy]

Shortly after this, Marceline and Simon move into an abandoned penthouse apartment and see ghosts for the first time; likely victims of the Mushroom War. It's 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, Beyond this Earthly Realm]

non-canon information
Finn and Jake come across Simon and Marceline while they are travelling through time after escaping the Vanishing Point. They tell Marceline to look after an object called 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]

As Simon looks after Marceline and sees her grow into a capable person, he begins to wonder what his life would be like in a world where he is no longer fighting for her survival every day. [Simon Petrikov]

---

5 AMB / 2015 CE

The Demon and the Tidal Wave

After realising that he is not going to be able to look after Marceline for much longer due to his rapidly declining mental health, 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's demon half must originate from. He pledges to find her father before he completely loses his mind. [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. [The Enchiridion & Marcy's Super Secret Scrapbook]

Even though he stops writing the journal, Simon scribbles many of his thoughts onto any bits of paper he can find. Some of them are notes to Marceline which she won't get to read for a millennium to come. [I Remember You]

Shortly after this, an enormous tidal wave hits the city. The detonation of the Mushroom Bomb, the impact of the Catalyst Comet, or the general elasticity of the world could all be responsible. 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]

c. 8 AMB / c. 2018 CE

Simon's Departure

Eventually the water stops rising, and Simon and Marceline arrive in another ruined city. [Everything Stays]

Ever since he first put it on, the crown has been urging Simon to re-establish Evergreen's realm of ice. This urge has begun to endanger Marceline, so he finally decides he must leave her. But before he does, he finds a copy of Mystic Rituals and their Space Time Applications, the book he co-authored with Betty Grof. The rituals it documents, which were useless before the war, are now working magical spells. One of the rituals can be used to open a portal to the Nightosphere. And so at last, Simon is able to contact Marceline's father: Hunson Abadeer. [The Enchiridion & Marcy's Super Secret Scrapbook]

The "binding spell" cast by Simon presumably ensures that Hunson and Marceline will someday meet each other. [The Enchiridion & Marcy's Super Secret Scrapbook]

non-canon information
Hunson and Simon briefly talk during their encounter, and Simon tells Hunson he has an obligation to keep Marceline safe. But Hunson says he is busy "quelling an uprising" in the Nightosphere and that he should tell Marceline to summon him herself later. [Marcy & Simon #3]

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 that he somehow procured, and instructions on how to open a portal to the Nightosphere so that she can someday summon her father. Then finally, after several years together, Simon leaves Marceline on her own, just like Elise did before him. [Everything Stays, The Enchiridion & Marcy's Super Secret Scrapbook, Obsidian]

c. 8 AMB / c. 2018 CE

The Fries Incident

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, since they believe he can help them vanquish the tribe of vampires that threatens their pack. Using the instructions left by Simon, the two werewolves successfully open a portal to the Nightosphere. Hunson arrives on Earth and bursts uninvited into Marceline's makeshift fort. [The Enchiridion & Marcy's Super Secret Scrapbook, Marcy & Hunson]

To Marceline's horror, Hunson immediately begins stealing souls. He takes the souls of Remi and Rosella, reducing Marceline's new friends to lifeless husks. Marceline is mortified. But despite this, she knows that this is probably her only opportunity to get to know her father, so she tries her best to put the ordeal behind her and get along with him. [The Enchiridion & Marcy's Super Secret Scrapbook]

Their relationship becomes more positive after a day at an abandoned carnival, and Marceline believes she is beginning to understand her father's motives. Hunson decides to give his daughter the Abadeer Axe, calling it a family heirloom. [The Enchiridion & Marcy's Super Secret Scrapbook]

Unfortunately, this friendship between father and daughter 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. But instead of assisting the pack, Hunson does something far worse. In a repeat of his previous actions, he steals the souls of the entire werewolf pack, claiming that he "helped" them since the vampires would have killed them instead. Upset with him, Marceline goes into the truck stop and makes herself some comfort food: a delicious box of fries. But while she has her back turned, Hunson commits one last terrible crime. He eats the fries. This is the last straw. In a rage, Marceline banishes him back to the Nightosphere, abruptly ending his nine day visit. [The Enchiridion & Marcy's Super Secret Scrapbook]

Marceline, alone once again, sets out to continue searching the wreckage of the world for survivors. Shortly after the fries incident, she writes the Fry Song, a ballad about her father. This is one of the first of many songs she will write over the course of her life. [The Enchiridion & Marcy's Super Secret Scrapbook, It Came from the Nightosphere]

non-canon information
In an interview with Teen Zine, Marceline tells a completely different story regarding the fries incident. It's possible that she made this story up to avoid telling the truth. [The Adventure Time Encyclopaedia]

c. 10 AMB / c. 2020 CE

Schwabl and Daniel

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, with the exception of just one creature: a dog, that somehow managed to survive all this time on the food in the mall's pet shop. Marceline adopts the dog and names it Schwabl. Having spent so much of her life dealing with complicated people like Simon and Hunson, Schwabl is a nice change of pace. [The Enchiridion & Marcy's Super Secret Scrapbook]

At some point, Marceline converts the Abadeer Axe into an electric bass guitar and learns to play it. She is still able to proficiently wield it as a weapon as well. [It Came from the Nightosphere]

One day, Marceline meets a talking unicorn called Daniel while sleepwalking. She befriends Daniel and is thrilled to have a new companion. But almost immediately, the unicorn is killed by vampires. Even though the entire encounter could have just been a dream, Marceline pledges to avenge her friend, and decides that she will slay every vampire she can find. She learns to fight from books in the abandoned mall's library. [The Enchiridion & Marcy's Super Secret Scrapbook]

Meanwhile, the world is beginning to lapse into a new ice age. This is probably caused by a combination of Simon establishing his realm of ice and some kind of magically augmented nuclear winter. [The Enchiridion & Marcy's Super Secret Scrapbook]

c. 10 AMB to 13 AMB / c. 2020 CE to 2023 CE

Marceline the Vampire Hunter

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 discovery that the vampires are hunting human survivors further encourages Marceline to seek them out and slay them. [The Enchiridion & Marcy's Super Secret Scrapbook, The Empress Eyes]

Before long, Marceline is a proficient vampire hunter and tracks down the Fool: a member of the formidable Vampire Court. She manages to force a wooden stake through his heart, destroying him in a puff of glittery smoke. She realises that this smoke is actually the Fool's soul, and discovers that she can use her soul sucking powers to absorb it. Taking the Fool's soul grants Marceline access to his power of flight; the first of many supernatural abilities that Marceline will inherit from hunting the Court. [Everything Stays]

One day, while trying to catch food, Marceline 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. The bunny girl is named Jo. To begin with, the tribe runs away from Marceline because of her sharp demon teeth and her ability to fly, but eventually come to trust her. Marceline has finally found a place where she belongs. Despite how terrified Jo was during their first encounter, she and Marceline become good friends. [Everything Stays, Islands graphic novel]

The second member of the Vampire Court encountered by Marceline is the Empress. 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. She may also have inherited the Empress' power of hypnosis, but if so she chooses not to use it. It's possible that Marceline sees Simon again during this ordeal, for the first time since he abandoned her. If that is the case, then they do not stay together for long. [The Empress Eyes]

Marceline decides to take a personal journey away from the tribe to visit the city where Simon abandoned her, for nostalgic reasons. 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. The tribe spends its time hiding from the third member of the Vampire Court: the Moon. Marceline stakes the Moon and takes her soul, inheriting her self-healing powers. Marceline becomes impervious to almost all physical harm, able to heal from wounds instantaneously. The second tribe of humans runs away before the fight, and Marceline never sees them again. [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 succeeds in killing all the vampires, because the atmosphere is changing and the nuclear winter is approaching. Their plan is to refurbish a large pre-war cargo ship and sail it out to sea to seek a new home. [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 Hierophant, the fourth member of the Vampire Court. She absorbs his shape-shifting powers, which allow her to take the shape of many different creatures. [Everything Stays]

The fifth and final member of the Court is the Vampire King. With all his minions destroyed and the rest of the Court slain, he is the very last of his kind. Marceline and the Vampire King battle on the deck of the human ship, and eventually Marceline manages to force her stake into his chest. Recognising that he is defeated, the King sees only one way to save his race. As Marceline pushes her stake through his chest towards his heart, the King pushes his fangs into her neck. Finally, the King dies, but not before Marceline has been successfully turned into a vampire. [Everything Stays, Vamps About]

Marceline takes on the title "Marceline the Vampire Queen", and for unknown reasons she decides to remain on the mainland while the humans set sail without her. [Evicted!, Islands graphic novel]

non-canon information
Some accounts suggest that Marceline is an actual queen who rules over a race of vampires, but this is false. Marceline is the last vampire, and a queen in name only, although she is presumably capable of creating more vampires by turning mortals. [Adventure Time #32: "Mystery Plop Part 1"]

Soon after her transformation, Marceline realises that she is allergic to sunlight and craves the colour red. Since she is technically now undead, she becomes immortal and stops ageing in her late teens. After accidentally killing her dog Schwabl by drinking his blood, she tracks down the group of wizards who obtained the Enchiridion following the war 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 Super Secret Scrapbook shows that Schwabl was red before Marceline resurrected him, but the Stakes miniseries and the 2015 Spoooktacular show that he has always been white. This is a minor continuity error.

Due to the advancing winter, Marceline decides to use her undead powers to hibernate until it is over. She falls asleep in a cave with Schwabl, using the Enchiridion as a pillow. She remains in this state until the winter is over, for what may be hundreds of years to come. [The Enchiridion & Marcy's Super Secret Scrapbook]

The Human Islands

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. Marceline's friend Jo is almost killed, but the humans are able to fend off the creatures. The next day, they make landfall at a large island where they are surprised to find even more humans. Two Bread Tom and the leaders of the other tribes begin fabricating a new society and name their new home "Founders' Island". [Islands graphic novel, Min and Marty]

Before long the humans have established a large and successful colony. Free from the threat posed by the vampires and the other hostile creatures on the mainland, most islanders no longer wear their protective animal hats. One day, Two Bread Tom decides that he wants to explore more of Founders' Island. He takes Jo and another islander named Michiko with him, thinking it will be nothing more than a safe hike through the woods. However, Jo gets abducted by a giant bird and carried to the other side of the island, and spends weeks making her way back again. In the meantime, Tom believes she has been killed and blames his own carelessness for her death. 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. The islanders are thrilled when Jo returns safely, but she actually disagrees with Tom's plans to seal them off from the rest of the world. In the end, she and a group of the other islanders rebel and run away from the colony before the Guardian can be completed. [Islands graphic novel]

The humans on Founders' Island 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 isolationist ideology. The tribe leaders, including Two Bread Tom, become deified in the islanders' mythology as the legendary "Founders". The fate of Jo and the rebels is unknown. They become known as "hiders"; a derogatory term used for anyone who tries to escape the safety of the Islands. [Hide and Seek, Min and Marty]

The humans also colonise two other islands in the chain: they establish a major colony on Hub Island, which was originally a desert but was terraformed by the humans, and on an unnamed island they build the infrastructure for a VR game called Better Reality, which allows many humans to retreat into a virtual world. [Hide and Seek, Imaginary Resources]

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. [Helpers]

Over time, almost all of the humans remaining on the mainland die out. Due to the islanders' isolationism, none of the non-humans on the mainland know of the existence of the Islands, and most non-humans assume that humankind has finally gone extinct. [Her Parents]

The Land of Ooo

A chunk of the western former United States becomes isolated and forms a small island continent. This continent becomes known as the Land of Ooo. The formation process is incredibly quick, taking less than a thousand years in total. Much of the cityscape becomes completely submerged under the ocean. Other parts of it are buried underneath deserts, or reclaimed by nature. Huntress Wizard claims that the most ancient part of the Land of Ooo is the Heart of the Forest. [Ocean of Fear, All the Little People, James, Simon Petrikov]

non-canon information
According to one account, the Land of Ooo is to the west of the giant crater, suggesting that most of the rest of the United States was completely wiped off the face of the planet. [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. [Islands graphic novel, The Enchiridion & Marcy's Super Secret Scrapbook]

The Land of Ooo is a volatile and unstable place. Its existence is threatened many times by many different events and adversaries, but it remains intact and habitable for at least the next two thousand years. [Lemonhope Part Two]

It is not known what happens to the rest of the world. It is likely rendered inhospitable by the effects of the Great Mushroom War: radiation, extreme weather, and dangerous magical events. [Islands graphic novel]

The Music Hole believes she has been singing since the beginning of Ooo. [The Music Hole]

Some time in the early history of Ooo, the Glass Kingdom is formed when the desert is struck by what the glass people call a "magic bolt of lightning". Shortly afterwards, a baby sea creature flees into a crevice under the kingdom after losing its siblings to a predator. The creature is sealed within the kingdom's Furnace, where it grows into a mighty dragon named Molto Larvo. [Obsidian]

Before 149 AMB / Before 2159 CE

The Return of Wizardry

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. The magic users of the Land of Ooo gravitate towards the ancient settlement of Wizard 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". [Wizards Only Fools, Betty]

Among other developments, a new school named Wiz Arts is built within Wizard City. It is coincidentally constructed directly above the tomb of Coconteppi, which has remained buried there since Coconteppi's death millions of years ago. The Cult of Coconteppi is secretly founded by a group of dark wizards who wish to revive him and bring about the so-called Second Age of Terror, which is the prophesied destruction of the world at the hands of Coconteppi. At some point, Grand Master Wizard becomes the ruler of Wizard City. [Wizard City, Wizards Only Fools]

Elsewhere, in 149 AMB (2159 CE), 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. [Wizard]

Meanwhile, the magical nuclear winter is subsiding. Evergreen's crown still doesn't allow Simon to die, and he has become a lonely and senile old wizard. He partially succeeds in establishing the Realm of Ice, by constructing a kingdom in the north of Ooo known as the Ice Kingdom. Simon takes the name "Ice King", and eventually forgets his real name. [I Remember You]

Bonnie and Neddy

The Mother Gum, the strange being who helped Marceline and Simon during the early years of their post-apocalyptic journey, begins to gestate two children named Bonnibel and Neddy. Although she will not learn it for some time, Bonnibel is the reincarnation of the Candy Elemental following the death of the previous one in the Great Mushroom War. [Simon & Marcy, Bonnie and Neddy, Elemental]

Bonnibel is born first, shortly followed by her brother Neddy. 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 a home for herself around the tree. [Bonnie and Neddy]

c. 185 AMB / c. 2195 CE

The First Candy People

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, whom she names Aunt Lolly, Cousin Chicle and Uncle Gumbald. [Bonnibel Bubblegum]

Initially her new creations are obedient, helping her to expand her small settlement around Neddy's tree, 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 with butterscotch, creating Lake Butterscotch. Gumbald is furious that his niece has undermined his work, and hates the fact that she believes she's in charge just because she is his creator. Tired of her control issues, Gumbald, Lolly, and Chicle unite and devise a plan to depose Bonnibel by creating a potion called "dumdum juice". This potion will render her completely stupid and unable to meddle in Gumbald's plans. He creates a candy person named Mr. Cream Puff to take Bonnibel on a date to distract her, then double-crosses Molly and Chicle by testing the dumdum juice on them, transforming them into candy people; a piñata named Manfried and a cookie named 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 a punch bowl named Punchy. [Bonnibel Bubblegum]

Seeing how happy and carefree these new creations are, she decides to create more of these dumb and docile candy people, rather than peers who can match her intellect and potentially turn on her like Gumbald did. She decides that she is only comfortable when she is the one in charge. In further revenge for Gumbald's actions, Bonnibel steals his plans to construct a city and undertakes the project herself. She claims the title of Princess Bubblegum, and rules over her new candy people. [Bonnibel Bubblegum]

Unbeknownst to her, Gumbald, Chicle, and Lolly's original selves remain helplessly trapped within their new goofy façades for over eight hundred years to come. [Come Along With Me]

Princess Bubblegum begins the construction of her new city, which she names the Candy Kingdom. At its centre lies the tree under which Neddy dwells. Bubblegum plants forests of cotton candy and taffy trees, and instructs her subjects to mine the ground beneath the kingdom for a material called rock candy. The kingdom is surrounded by a radioactive river, which she begins filling in. She locks the Mother Gum away in the dungeon of her new kingdom to keep them safe. [Bonnie and Neddy, Varmints, The Vault, Explore the Dungeon Because I DON'T KNOW]

Marceline and Bonnibel

One day, Marceline Abadeer wakes up from her long hibernation, still alive thanks to the fact that vampires don't age. In the strange and magical new world she has woken up in, she becomes a punk rock musician performing for the denizens of Ooo using her trusty axe bass. Princess Bubblegum becomes a fan of Marceline's music, and at one of her gigs Marceline throws her shirt to the princess. The rock shirt becomes Bubblegum's most treasured possession, and the two of them fall in love. [The Enchiridion & Marcy's Super Secret Scrapbook, Obsidian, What Was Missing]

non-canon information
According to one account, Marceline buys the rock shirt for Bubblegum while they are on a date at a punk show, after somebody spills food down her clothes. However, this is now known to be false. [P.B. & Marcy]

They live happily together for a while, as Princess Bubblegum continues to work on the Candy Kingdom and Marceline continues to pursue her music. 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. Bubblegum and Marceline sometimes explore the rock candy mines together, and after a lot of persuasion Marceline manages to get Bubblegum to graffiti on the walls. [The Enchiridion!, Varmints]

Marceline and Bubblegum begin to drift apart after Bubblegum becomes too caught up in the management of the Candy Kingdom and isn't able to make as much time for Marceline. [What Was Missing, Varmints]

This all comes to a head when Princess Bubblegum is summoned by the people of the Glass Kingdom to help defeat Molto Larvo, the dragon which formed in the Furnace beneath the kingdom and now threatens to wreak havoc. Marceline tags along and begins to get on Bubblegum's nerves due to her apathy towards the fate of the glass people. In an outburst, Bubblegum tells Marceline to go home. Marceline is sensitive to being abandoned as she blames herself for driving others away. Fearing that she is losing Bubblegum, she decides that the only way to avoid being hurt again is to take action herself. So Marceline, in her anger, performs a song that brings an end to their relationship. [Obsidian]

The song succeeds in defeating Molto Larvo, who withdraws into the Furnace upon hearing the music, and remains dormant for several hundred years to come. The glass people make Marceline a saint, and she goes down in their history books as the one who defeated the dragon. Once a year, the glass people gather to sing the song and keep the dragon sealed away, although the lyrics get corrupted beyond recognition over time. [Obsidian]

Meanwhile, Marceline and Princess Bubblegum are both devastated by the breakup. Bubblegum still keeps hold of the rock shirt that Marceline gave her when they first met. She never wears it in public, but she wears it to bed all the time, which charges it with a huge amount of emotional magic power. [What Was Missing, Sky Witch]

Marceline begins writing her angsty five hundred year journal at around this time. At some point she journeys to a dimension called the Underworld and joins a gang with three ghosts named Wendy, Booboo, and Georgie. 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. [Heat Signature, Marceline's Closet, The Enchiridion & Marcy's Super Secret Scrapbook]

note
It isn't clear whether Marceline and Bubblegum's relationship happened before or after the events of The Vault, when Princess Bubblegum was dating Mr. Cream Puff.

Hundreds of years AMB / 2??? CE

Shoko

When the Blue Catalyst Comet first struck the Earth, its Agent of Change took the form of a butterfly. When the butterfly died, it was reincarnated as a mysterious pink blob. And when the pink blob died, it was reincarnated as a girl named Shoko. She claims that her parents traded her right arm for a computer when she was a child, and then abandoned her in a dojo. With nowhere else to turn, she becomes a thief-for-hire, working for the various gangs and clans who have begun to crop up across the Land of Ooo. She travels with her tiger, a previous incarnation of a certain Jake the Dog. [The Vault, Together Again]

By this time, Princess Bubblegum is dating Mr. Cream Puff. It's not certain whether these events take place before or after her breakup with Marceline. If they take place before, Princess Bubblegum probably just never bothered breaking up with Mr. Cream Puff. If they take place afterwards, Mr. Cream Puff might be a rebound relationship. [The Vault, Obsidian]

Shoko 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 Candy Kingdom, which is still under construction at this time. She gains Princess Bubblegum's trust and helps her complete her secret project: the Gumball Guardians. These are powerful robots who are charged with protecting the Candy Kingdom from evil. Bubblegum activates them using the power of her blue amulet. [The Vault]

Despite the initial plan, Shoko becomes conflicted about completing the job after Bubblegum gifts her a new robotic arm. However, her fear of the Bath Boy Gang outweighs her guilt, and she attempts to take the amulet anyway. She steals it while Bubblegum is sleeping, but she is spotted and attacked by one of the newly constructed Gumball Guardians, who sends her hurtling into the radioactive river surrounding the kingdom. Mutated and disfigured, but endowed with a new biological arm, Shoko crawls away and dies under the sapling of a willow tree. [The Vault]

The sapling grows around and through Shoko's corpse, which is still clutching the blue amulet. It grows into a mighty willow which will one day be turned into a house named the Tree Fort. [The Vault]

Hundreds of years AMB / 2??? CE

The Tyrant Bubblegum

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 a victim and Bonnibel as a brutal oppressor. [The Thin Yellow Line]

This reputation is not helped by several questionable 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 a group of candy people known as the Banana Guard. However, they are largely ineffective due to the fact that Bubblegum is still creating all her subjects to be dim and docile. So instead, Princess Bubblegum turns to robotics again. She constructs a fleet of robotic warriors called the Rattleballs. [Rattleballs]

Bubblegum takes extreme action by having all of them destroyed, and reinstates the Banana Guard. A single unit, who simply names himself "Rattleballs", escapes the execution. He leaves the walls of the kingdom and goes to live in hiding in the dump. At some point he goes horseback riding and gets a gumball lodged in an awkward spot, leaving him with a permanent cough. [Rattleballs]

In her controlling paranoia, Bubblegum establishes mass surveillance networks in her kingdom to watch her citizens and track their every move. [You Made Me, Nemesis, The Cooler, Graybles 1000+]

Unlike Bubblegum herself, most of the candy people appear to be susceptible to old age and death. Bubblegum's former boyfriend Mr. Cream Puff dies at some point. However, not all candy people have such short lives; Crunchy, Punchy, and Manfried seem to share her longevity. In addition to this, she routinely clones her subjects whenever they get lost or die. [Slumber Party Panic, James]

Marceline accuses Princess Bubblegum of being a dictator. [Obsidian]

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 power of the liquid produced by her brother Neddy. Her territory expands to encompass a large portion of the grasslands. She builds a grand castle around Neddy's tree and spends a lot of her time locked up inside studying science and inventing new technology. [Bonnie and Neddy, Burning Low, The Suitor]

non-canon information
In addition to the Banana Guard and the Gumball Guardians, Bubblegum instates the Royal Hero Draft, a scheme to recruit warriors and heroes who will defend the kingdom. It is likely that many of the Candy Kingdom's champions through history are recruited via this scheme. [Candy Capers #1]

Hundreds of years AMB / 2??? CE

AMO and BMO

Many years after the Great Mushroom War, Moseph Mastro Giovanni is still alive at his factory in the Land of Ooo's Desert Lands. He claims that the only part of him that remains human through all this time is his skin. Moe builds many robots in his "MO" range for various purposes. Some of them keep him alive in his old age, some guard and maintain the factory, and some are sent off into the world beyond. His two most notable creations are AMO, who is built to receive love, and BMO, who is built to provide it. [Be More, The More You Moe The Moe You Know]

BMO and his siblings are incredible feats of engineering. As well as having an advanced human-like personality within his heart-shaped core, BMO also has within him a device called an "infinity box", which can adapt to fill many different roles. One of the functions of the infinity box is a button capable of transporting individuals into BMO's "main brain game frame", from which they can enter into the world of a video game. BMO also has within his circuitry some kind of medal as well as a diploma. The MOs have no gender and use various pronouns interchangeably, but BMO is most often referred to using masculine pronouns. [Guardians of Sunshine, Be More, Be More storyboard (The Art of Ooo)]

AMO, on the other hand, is neglected by Moe and goes insane from a lack of love, eventually leaving the factory on a pilgrimage. [The More You Moe The Moe You Know]

Hundreds of years AMB / 2??? CE

The Fire Kingdom

The MOs are not the only machines that Moe builds. As previously mentioned, he probably has some involvement in the design of the islanders' Guardian and the Martian colony. Furthermore, he is responsible for the construction of legendary machines known as the Sleeping Fire Giants. [The More You Moe The Moe You Know]

The Fire Giants ignite the Fire Kingdom in the south of Ooo, allowing for the rise of a race of flame people. In the centuries that follow, the Fire Kingdom becomes 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. [The Cooler]

non-canon information
The documentation for how to operate the Fire Giants is eventually 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 will later become known as "Flame King", plots to take the Red Throne by murdering the impeding heirs until it is rightfully his. One of those murdered heirs is Flame King's older brother. His enraged nephew and niece, Furnius and Torcho, swear vengeance upon Flame King, and secretly escape their executions. [Ignition Point]

Hundreds of years AMB / 2??? CE

The Other Kingdoms

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. However, a few are large enough to rival it. The princesses and other leaders form various political organisations to keep the peace, such as Princess Day and the Grand Meeting of Ooo Royalty. 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 Duke, Princess Day]

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. 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. [Bonnibel Bubblegum, Trouble in Lumpy Space, Incendium]

The Slime Kingdom eventually falls under the rule of Slime Princess, who is a reincarnation of the Slime Elemental. [Love Games, Elemental]

Via unknown means, several of the princesses of Ooo each come into possession of one of the nine "Gems of Power". These gems can be used to activate the Enchiridion when inserted into its front cover. The gems are used by the princesses as crown jewels, passed down through the generations. Princess Bubblegum and Slime Princess each own a Gem of Power. Ice King also owns a Gem of Power: the central gem of Evergreen's Crown, which was once an eye of Magwood. [The Lich, Evergreen]

Turtle Princess becomes 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. [Paper Pete]

Magic Man's Banishment

In his grief and madness over the loss of Margles, Magic Man has spent many centuries tormenting the people of Mars for fun. Most notoriously, he creates three plagues; the Plague of Shadows causes people's shadows to come to life and attack them, the Plague of the Oneness causes every Martian to become stuck hand in hand, and the Plague of Hair causes all the water to turn into hair. The Martians get so thirsty that they drink it, and it makes them go bald, hence why many of them wear "groovy headgear". [Sons of Mars]

His last act against the Martians is chaining them all together and driving over them with a school bus. After escaping from the chains, Abraham Lincoln gives up trying to reason with Magic Man and finally sentences him to banishment. [Normal Man]

Magic Man is left in the Land of Ooo 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 its inhabitants. [Freak City, 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. [You Forgot Your Floaties]

Gunter Arrives in Ooo

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. Ice King adopts Orgalorg and is compelled by the crown to rename him "Gunter"; a corruption of the name of Evergreen's dinosaur servant "Gunther". This happens sometime before 885 AMB. [Orgalorg, Evergreen]

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. [Reign of Gunters]

---

c. 913 AMB / 2923 CE

The Winter King

In an alternate universe, the Ice King figures out a way to "cure" himself of the madness of Evergreen's crown. But rather than being dissipated entirely, the madness is transferred to Princess Bubblegum via a curse. The result is that their roles are swapped. Ice King becomes the sane ruler of a beautiful Ice Kingdom, known as the Winter King, while the Candy Kingdom becomes the domain of a maddened, saddened Princess Bubblegum, who becomes known as the Candy Queen and makes frequent attempts to kidnap her counterpart as he once did to her. [The Winter King]

Despite no longer possessing the crown's madness, the Winter King is still not Simon Petrikov. Marceline is notably absent from his life, presumably severing ties with him after he became this twisted corruption of the man she had once seen as a father, and after he turned her ex into a nutcase. The Winter King deals with this by making a new Marceline out of ice, to be his daughter forever. [The Winter King]

None of this transpires in our main timeline, where the plot remains on track, Ice King remains his mad, sad self, and Princess Bubblegum continues as ruler of the Candy Kingdom.

Billy and the Rise of The Lich

Billy is a great hero of the Land of Ooo, who becomes a role model to many aspiring adventurers. He wields a sword named Nothung, lives in a cave called "Billy's Crack", and has a magical dog who dies at some point before 996 AMB. He has a girlfriend named Canyon, who is a water elemental (not to be confused with the actual Elementals). [His Hero, Billy's Bucket List]

One of Billy's most legendary altercations is his battle against The Lich. After spending nearly a thousand years gathering his power following the Great Mushroom War, The Lich makes his first attempt to end all life, and by proxy the Multiverse. [Mortal Folly]

Billy and The Lich battle at The Lich's Well of Power and end up taking the fight to the Candy Kingdom. The Lich loses one of his horns in the battle and is struck down by Billy's legendary gauntlet. He becomes imprisoned in amber within the canopy of Neddy's tree, still alive and still hungry for destruction. Bubblegum guards the tree for years to come, to prevent his escape. Even though Billy goes down in history as having cast down The Lich, for some reason he gives up his heroism and retreats into himself, becoming a pacifist recluse. It's possible he is ashamed at his inability to end The Lich for good. [His Hero, Mortal Folly]

Canyon ends her relationship with Billy in 995 AMB, following his decline. [Billy's Bucket List]

The Earl of Lemongrab

Due to the absolute control that Princess Bubblegum exerts over her subjects, she realises that the entire weight of the Candy Kingdom lies on her shoulders. If something bad was to happen to her, the kingdom would also fall. So she attempts to create an heir to the kingdom's throne. The result of her experimentation is the Earl of Lemongrab. [Too Young]

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. [Too Young]

Animals of Ooo

Before the war, most of the animals 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 immigrants from other dimensions, or mutated versions of Earth's native species. Among them are bears, foxes, ants, geese, dogs, fish, and many others. [Storytelling, Sad Face, President Porpoise is Missing!]

Choose Goose is a travelling merchant who tours the Land of Ooo trading mystical objects. [Blood Under the Skin, The Real You]

non-canon information
One account tells the origin story of Choose Goose. 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 by turning his limbs and neck into comical noodle-like appendages. 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 on the life of a travelling merchant. [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 instead 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. The bat he befriended, however, does not appreciate his fame, and leaves him. [Horse and Ball]

Tree Trunks' Wild Past

A pygmy elephant named Tree Trunks grows up in the Tiny Mammal Kingdom. When she is a child she dreams of joining the Candy Kingdom's Banana Guard. [Ring of Fire, Banana Guard Academy #1]

Tree Trunks' high school boyfriend is a rhino named Randy, with whom she releases a vinyl titled Miss Tree Trunks Loves You. After graduating from high school, the two of them immediately get married. However, Tree Trunks abandons Randy just before their honeymoon to seek adventure on the high seas. [Two Swords, 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 crewmate 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. [Ring of Fire]

Meanwhile, an individual travels the land claiming to be the "One True 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, including Tree Trunks. [Hot Diggity Doom, Lady Rainicorn of the Crystal Dimension, Apple Wedding]

non-canon information
According to one account, the self-proclaimed King of Ooo is a member of a hive of "wax hustlers". [Steve Wolfhard]

Upon returning to the mainland and giving up piracy, Tree Trunks invests her pirate treasure into establishing a large-scale shipping business which apparently has ties with MO Co. She begins wearing a glass eye. She falls in love with her secretary, a seal named Wyatt, and they get married by the King of Ooo soon after. Tree Trunks sells her company, donates her vast wealth to the King of Ooo, and settles in the Candy Kingdom with Wyatt where they maintain an apple orchard. This is her longest lasting marriage to date, but they divorce some time between 984 and 996 AMB due to Wyatt's insatiable appetite for apple pie and his unadventurous personality. Tree Trunks becomes famous for her apple pie, which is sold at the Ooo Mall. [Joshua & Margaret Investigations, Ring of Fire, Ice King #2]

Tree Trunks' fourth marriage is a polyamorous relationship with a group of grey aliens, with whom she has five hybrid children. The events leading up to this bizarre relationship are unknown. The aliens only visit her every few years, so she continues living on her own in her orchard in the Candy Kingdom. [High Strangeness]

Marceline and Ash

Marceline begins dating a wizard named Ash. By this time, the willow tree that grew over Shoko's corpse has been turned into a house: the Tree Fort. Marceline and Ash move in together, and Marceline carves an "M" into the bark to indicate her ownership. [Evicted!, Memory of a Memory]

While Simon has been completely pushed out of his mind by the Ice King at this point, 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. [I Remember You]

Possibly due to this, Ash and Marceline eventually move out of the Tree Fort to a shack in the woods. Their relationship quickly becomes more fragile after Marceline begins to realise that Ash is a sexist jerk. [Memory of a Memory]

non-canon information
Marceline leaves the red amulet that was given to her by Princess Bubblegum in the Tree Fort. The blue amulet is still being clutched by Shoko's skeletal remains beneath the fort's floorboards. [Adventure Time #25]

One day, without Marceline's permission, Ash sells Hambo, the teddy bear that Simon gave to Marceline when he found her after she was abandoned by her mother. It is bought by Maja the Sky Witch at a high price thanks to its high sentimental value, which is useful in spell crafting. As soon as Marceline finds out what Ash has done, she violently breaks up with him. [Memory of a Memory, Sky Witch]

The Tragedy of Warrior Princess

Two star-crossed lovers, Warrior Princess and Clarence, find themselves on opposite sides of a battle for an abandoned wind farm. [Ghost Princess]

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. This is the Squeez-E-Mart where Clarence will much later take his own life. [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.

The Islanders

The Human Islands are locked off from 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 camps. [Hide and Seek]

Despite this isolationism, someone named Alva and a group of other Swedish humans embark on an expedition from Founders' Island to another island in the chain called Back-to-Nature Island. They establish a small colony and experimental artificial weather systems to terraform the island like they did on Hub Island. However, something goes horribly 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. Nobody from Founders' Island or Hub Island comes to rescue her. Alva manages to befriend some of the wildlife, including a giant bear named Albert, and lives on her own in a teched-out tree base for the next fifty years or so. [Mysterious Island, Min and Marty]

All children born on the Islands are given a function from early childhood, and a child named Kara Strong (designation "Seeker X-J-7-7") is destined to be a seeker. She is part of a modern generation of seekers who 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, a human cyborg bioengineer named Doctor Gross. The chips serve the secret secondary function of giving Doctor Gross complete authority over her seekers' actions without their consent. [Hide and Seek]

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. [Hide and Seek]

Frieda, however, begins to develop a desire to see the rest of the world; a desire which would make her an outlawed hider if expressed publicly. Nevertheless, she secretly begins making plans for escape. [Hide and Seek]

Lumpy Space Princess

Lumpy Space Princess, commonly abbreviated to LSP, is born to her parents Lumpy Space King and Queen in 981 AMB. LSP is heir to the Lumpy Space throne, and the reincarnation of the Lumps Elemental, a being capable of negating the magic of the other four elements: fire, ice, candy, and slime. LSP seems to be unaware of her elemental abilities, however. [Trouble in Lumpy Space, The Prince Who Wanted Everything, Skyhooks II]

She is raised in Lumpy Space, a dimension rife with teen drama. She attends school for a while where she has a lab partner who she calls "Ugly Johnnie" 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 as of 996 AMB. Despite this, LSP sometimes prefers her own company, and grows to miss it as she gets older and becomes surrounded by more and more social pressure. [Skyhooks II, Bad Timing, Trouble in Lumpy Space, Summer Showers]

984 AMB / 2994 CE

Phoebe the Flame Princess

Phoebe the Flame Princess is born to the Flame King, ruler of the Fire Kingdom. Although she and her father do not know it, she is the reincarnation of the Fire Elemental. While she is still a baby, the Flame King hears a prophecy that her powers will be far greater than his own, and so he 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. Flame Princess, who doesn't know any better, burns down the lumberjack's house and begins carving a path through the forest. After a destructive rampage through Ooo, she reaches the Candy Kingdom and is intercepted by Princess Bubblegum wearing a heatproof suit, who takes her back to the Fire Kingdom. [Earth & Water, Elemental]

Princess Bubblegum believes that if Flame Princess is ever allowed romantic interaction, her emotional reaction could burn the entire world. Begrudgingly, Flame King has his daughter imprisoned in a lantern above his throne for the next fourteen years of her life, where she is totally deprived of friendship and freedom. Princess Bubblegum is satisfied with this arrangement. [Incendium, Burning Low]

984 AMB / 2994 CE

Joshua and Margaret

Two talking dogs run a private investigation business named "Joshua & Margaret Investigations", from an office in the ruins of an old human city. In the future, a creature called Clockbear hides in the attic of Joshua & Margaret Investigations and causes several "time slips" between the 980s and 1001 AMB. Joshua and Margaret's first case is a "poltergeist" haunting the office, although unbeknownst to them it is actually their future children attempting to communicate through time using Clockbear's powers. [The First Investigation]

Margaret soon becomes pregnant with her and Joshua's child, so Joshua picks out what seems like a danger-free case; a pie burglary reported by Tree Trunks. Margaret doesn't believe that her pregnancy should get in the way of their work, but begrudgingly agrees to take the case. [Joshua & Margaret Investigations]

Tree Trunks tells them that a monster is stealing her pies, since it leaves behind huge tracks. They discover that the "monster" is actually just Tree Trunks' husband Wyatt wearing a pair of snow shoes; one of the factors behind their later divorce. As Joshua and Margaret are leaving, they come across the trail of a real monster, and Margaret begins tracking it despite Joshua's objections. It turns out to be none other than Warren Ampersand, the shape-shifting alien from Nerraw. Warren bites Joshua's head before retreating through a portal back to his own world. Warren had impregnated Joshua, and he later gives birth from where he was bitten on his head. Moments later, Margaret gives birth to their own child in a more traditional fashion. Joshua and Margaret name their child Jermaine, and they also raise the shape-shifter's offspring as their own, naming him Jake. [Joshua & Margaret Investigations, Jake the Starchild]

Jake the Dog is a half dog half shape-shifter hybrid. This bizarre mix gives him the same appearance as Joshua, but the shape-shifting abilities of Warren Ampersand, which he later dubs his "stretchy powers". Additionally, Jake is the reincarnation of the thief Shoko's tiger. Jake's half brother Jermaine is a much more ordinary individual. [Joshua & Margaret Investigations, Together Again, Jermaine]

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. [Joshua & Margaret Investigations, Earth & Water]

984 AMB / 2994 CE

Minerva and Martin

Martin Mertens is a human conman living on Hub Island. His signature con is tricking hiders into gathering on the beach for fake escape plans and then reporting them to the seekers for capture, reaping reward from both sides. One day, a hider named Widow grows suspicious of Martin and makes him accompany her to the beach. Widow and the other hiders are captured by seekers 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. [Min and Marty]

Following this, the unlikely couple end up falling in love. They begin dating after Minerva helps Martin to avoid re-education, and they eventually move into a house together. Martin gives up his unsavoury profession and instead becomes a barber, while Minerva continues to become one of the most respected helpers on the Islands. [Min and Marty]

Meanwhile, Kara's friend Frieda begins to enact her own escape plan. She intends to construct a transport using stolen parts. Kara discovers that her best friend is a hider, but ultimately decides to help her rather than turn her in. However, Doctor Gross follows Kara to the coastline and activates her chip, commanding her to capture Frieda against her will. Frieda is sent to re-education and never makes another attempt to leave, eventually becoming a toymaker at a shop called Leksa Ker. [Hide and Seek, Helpers]

Minerva and Martin eventually have a child together, who they decide to name Finn Mertens. His designation in the Islands' database is "Infant P-G-8-7". Finn is the reincarnation of Shoko, and by extension a reincarnation of the Blue Catalyst Comet's Agent of Change. However, he will not discover this for many years to come. [The Invitation, Min and Marty, The Vault, The Comet]

Martin and Finn's Escape

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 Islands. In the resulting battle, Martin manages to blind one of the Guardian's eyes before being thrown out into the ocean. He and Finn become separated and both inadvertently leave the Islands. [Min and Marty]

Finn remains on the raft, surviving on breadsticks, and eventually washes up on the shores of Ooo. The experience leaves him with an extreme fear of the ocean, although he doesn't remember it. [Ocean of Fear, Min and Marty]

The dogs Joshua and Margaret discover Finn 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. Somehow, Joshua and Margaret find out that his name is Finn. It's possible it was written on his hat. Finn becomes known as "Finn the Human" due to the rarity of his species. The kindness of Finn's new adoptive parents later inspires him to pledge that he will help anyone in need, no matter how small their problem. [Memories of Boom Boom Mountain]

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 vague memories of his past. [The Visitor]

Meanwhile, back on Hub Island, Minerva is distraught over the loss of Martin and Finn, believing that Martin was a hider all along and has taken their baby. Doctor Gross dispatches Kara Strong, her most powerful seeker, in an attempt to retrieve them, but something goes wrong with the mission and Kara's transport crashes down in the Land of Ooo. Kara is left with severe amnesia and forgets almost everything, including her own name. Her chip stops compelling her to look for Martin and Finn, so she is left alone and without purpose in a strange new land. [The Invitation, Helpers]

She joins a tribe of "hyoomans"; humanoid fish creatures who live underground in an abandoned shopping mall called Beautopia. 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 to come. [Susan Strong, Beautopia]

985 AMB to 99? AMB / 2995 CE to 299? CE

Finn, Jake and Jermaine

During their early childhood, Jake, Jermaine, and Finn live in the Joshua & Margaret Investigations office with their parents. At some point, the family moves out of the office in the ruined city and into a large house atop a hill in the countryside. [Jermaine, 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. [Dad's Dungeon, Jake the Dad, Jake the Starchild]

In addition, Jermaine appears to take a back seat behind his two brothers. He isn't a powerful shape-shifter like Jake or an exotic human like Finn, 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, for which Joshua praises Jake, leaving him with a long lasting sense of guilt. [Crystals Have Power, 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. [Joshua & Margaret Investigations, The Witch's Garden, Henchman]

Joshua does decide to warn 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. [Abstract]

Despite their familial issues, all three children clearly love their parents.

On top of being a private investigator, Joshua is also an experienced demon hunter. At one point, 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: the Demon Blood Sword. However, Joshua stops him and steals the sword, storing it in a dungeon for Finn to find when he is older. Kee-Oth retreats to the Broke-up Dimension and plans his vengeance upon Joshua. [Dad's Dungeon, The Pit]

Finn and Jake begin using the Tree Fort as a base at some point before 996 AMB. Joshua records a hologram message directing Finn and Jake to the dungeon containing the Demon Blood Sword, and leaves it in the Tree Fort's attic. Finn and Jake are unaware that their cool new base still legally belongs to Marceline, as they have not yet encountered her. [Dad's Dungeon, Evicted!]

Tales from the Candy Kingdom

Eight hundred years after its foundation, the Candy Kingdom continues to thrive. Many of its subjects, the artificial candy people created in Princess Bubblegum's laboratories, eventually develop their own distinct backgrounds and personalities.

Peppermint Butler, one of Bubblegum's earliest creations, is created to be her servant. He fulfils this task, becoming the princess' loyal butler as well as one of her closest advisors. But on top of that, he develops a strange interest in the dark side of magic. Unbeknownst to Princess Bubblegum, he secretly becomes a dark magician and acquaints himself with several powerful entities including Hunson Abadeer and Death himself. Peppermint Butler appears to share Bubblegum's longevity, or is important enough to be regularly revived via cloning, and has a sharper mind than the average candy person. Using his dark magic abilities, he casts a curse on himself so that if he ever loses his skills and memories through exposure to dumdum juice, his past self will still be able to guide him onto the path of dark magic once again. [The Vault, Nemesis, Death in Bloom, Wizard City]

non-canon information
According to one account, Peppermint Butler also establishes S.W.E.E.T.S., the Candy Kingdom's secret service. [Adventure Time #41]

A candy corn rat named Science is another of Princess Bubblegum's earliest creations, even pre-dating the creation of Gumbald, Molly, and Chicle. She was likely created as a test for these more advanced creations. She remains a companion to Bubblegum throughout the centuries, and becomes a capable chemist herself. [Bonnibel Bubblegum, From Bad to Worse]

In 968 AMB, the first baseball event known as the "Annual Royal Banana Guard Post Season Apology Game" is held. [The Wild Hunt]

A young boy named Cookie, also known as Baby Snaps, is raised in an orphanage. It is unknown how he became an orphan; he might have lost his parents, or Princess Bubblegum simply might not have given him any in the first place. One day, Princess Bubblegum visits the orphanage and Cookie is amazed by her ability to make everything seem better and brighter. But then she unintentionally insults him, and he holds a grudge that eventually develops into a mental illness. [Princess Cookie]

A teenager named Betsy Pound Cake becomes stressed about her relationship with her boyfriend, Justin. She catches an illness which disfigures her arm to look like a crab claw, and ends up running away from home so that Justin would never see her disfiguration. She lives in a cave while studying medicine. Eventually she finds a cure for her crab hand, and returns to the Candy Kingdom where she becomes a nurse. She records her story in a diary which she rips apart and throws into the moat of the Candy Kingdom, as well as in a letter that she leaves in her cave house. [The Diary]

A banana person named 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. [Slumber Party Panic, The Suitor]

Two candy people named Root Beer Guy and Cherry Cream Soda are created by Princess Bubblegum, who decides that they will be married to each other. Cherry Cream Soda is a lawyer and Root Beer Guy works in a call centre. Root Beer Guy spends much of his free time reading detective novels, and in 989 AMB he eventually begins writing one of his own. He works on it for ten years. His obsession with his writing causes tension in the marriage. [Cherry Cream Soda, Root Beer Guy]

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. [We Fixed a Truck, Blank-Eyed Girl]

The captain of the Candy Kingdom's Banana Guard describes his rise through the ranks. [Banana Guard Academy #2]

A candy person named Todd Cupcake falls in love with a banana guard lady in 989 AMB. However, the lady tells him that she cannot have relationships outside the force, so Mr. Cupcake attempts to join the Banana Guard. His application is rejected, since he is not a banana. After a fruitless and expensive legal battle during which he loses his job, he promises to join the Banana Guard should the opportunity ever arise. He later begins dating another candy person named Chocoberry. [Banana Guard Academy #1, The Invitation]

A wizard calling himself the Dark Magister Templi Marble goes through a phase of kidnapping princesses, including Princess Bubblegum, in a fruitless quest for infamy and recognition. Eventually he attacks the Grand Master Wizard and sows the seeds of a story which eventually grows into a legend. Many wizards dream of being the one to defeat the Dark Magister Templi Marble.

Doctor Gross' Virus

Doctor Gross, the ethically unhinged bioengineer from the Islands, accidentally releases a deadly contagion upon the human race, which kills over half the human population. [Helpers]

Finn's mother Minerva uploads her consciousness into an army of robots, which are eventually able to contain and vanquish the virus. Hub Island becomes completely abandoned, and most of the surviving islanders move to Founders' Island, with the exception of Alva (who is still stuck on Back-to-Nature Island) and the Better Reality players. [Helpers, Mysterious Island, Imaginary Resources]

Doctor Gross, who knows she is guilty of causing the deadly epidemic, flees the Islands in her mobile laboratory and travels to the Land of Ooo, escaping the reach of the Guardian. She remains hidden to the people of Ooo, but she continues to experiment on animals, creating a variety of bizarre hybrids. She also further alters her own body using cybernetic enhancements that she dubs "mods" until she is eventually more robot than human. [Preboot]

According to one account, they move into a house without realising it is built above an abandoned collapsing crystal mine left over from the wars. [Marcy & Simon #5]

Despite the end of the Rainicorn-Dog Wars, tensions between the two species are still high. Bob and Ethel have a daughter named Lady Rainicorn, who begins dating Lee, a racist who spends his time committing hate crimes against dogs. [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 Earth with the weapon, where she goes into hiding. She begins living in a barn near the Candy Kingdom and becomes friends with Princess Bubblegum. [Lady Rainicorn of the Crystal Dimension]

Jake's Complicated Past

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 a criminal. Initially he is just a petty thief, using the pickpocketing skills taught to him by his father to snatch old ladies' purses, and selling stolen bikes in the seedier parts of the Candy Kingdom. But later, he becomes the leader of a notorious gang consisting of himself, a hypnotist named Gareth, a pair of impressionists named the Flying Lettuce Brothers, and an over-dramatic boy named Tiffany. With their combined abilities, they are a criminal force to be reckoned with. [Jake the Starchild, Apple Thief, One Last Job]

non-canon information
According to one account, Jake is eventually caught, and his criminal record causes him to lose his right to vote. [President Bubblegum]

A fantasy card game called Card Wars becomes popular, and an annual doubles tournament begins being held on an abandoned oil rig, with the first one taking place in 942 AMB. It is mostly attended by turtle people, but many different species take part. [Daddy-Daughter Card Wars]

Jake 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 championship title to someone named 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. [Daddy-Daughter Card Wars, The Great Bird Man, Card Wars]

Following this, Jake begins writing a newspaper advice column called Begs the Question. One fan, a squirrel, develops an obsessive hatred for Jake after his letters aren't printed in the column. Jake starts dating the fugitive Lady Rainicorn and learns to speak Korean so he can communicate more clearly with his new girlfriend. He also learns to play the viola. A worm named Shelby begins living in Jake's viola at some point. Shelby is apparently a priest. [The Duke, My Two Favorite People, The Pit]

Jake is very likely the true author of a misleading dating advice book called Mind Games, which is written under the pen name "Jay T. Doggzone". [Reign of Gunters, All the Little People, The Suitor, The Pit]

The End of Joshua and Margaret

After many run-ins with demons, aliens, and a wide variety of other adversaries, Joshua and Margaret finally kick the bucket. The cause of their deaths is unknown. It might simply have been old age; dogs age faster than humans. Finn and Jake bury them. [Billy's Bucket List]

Finn and Jake permanently move into the Tree Fort, leaving their brother Jermaine to begrudgingly take care of their dead parents' old house and all of Joshua's old demon artifacts. He believes he has a duty to preserve his parents' legacy. Unfortunately, the house comes under siege from hordes of demons attempting to retrieve their stolen possessions, and Jermaine becomes trapped, forced to spend his entire life repelling them using salt barriers and other magic. He loses almost all contact with his brothers, only making occasional psychic contact with Jake via shared dreams. [Crystals Have Power, Jermaine]

Saviours of the Drift

The Drift has been in a state of decay for nearly a thousand years. When Hugo arrived following the Great Mushroom War, he recognised that the fragile space station would not last long. Since then, he has been constructing the "Unity Pod", a new space station to save himself and his inner circle of former humans from the doomed fate of the station's other inhabitants. Building the Unity Pod requires vital parts to be scavenged from other pods, leading to their collapse. So, in creating his new home, Hugo is accelerating the destruction of the Drift. Hugo's robotic companion, CGO, comes to see the error of his master's ways, and for that he is discarded by Hugo and begins living in the station's trash heap. [BMO]

Martin Mertens, who has been adventuring through space ever since escaping Hub Island, arrives at the Drift and allies himself with Hugo, taking on the guise of a mysterious individual named Mr. M. He helps Hugo to scavenge more parts for the Unity Pod. Like many of the other inhabitants of the Drift, he hopes to secure himself a place on board by sucking up to Hugo. [BMO]

Meanwhile, BMO is sent out into the cosmos on board a MO Co spacecraft, apparently to start a potato farm on Mars. But instead, he is intercepted by a service droid from the Drift, who BMO names "Olive". This is the same service droid which saved Hugo and the grey elves and brought them to the Drift. She has been waiting ever since then for someone who would be able to put a stop to the damage Hugo is causing to the station, and seems to recognise BMO as that someone. [BMO]

Olive takes BMO to the Drift, where BMO takes on the role of the station's sheriff and begins working to fix the crisis facing its people. A teenage bunny person engineer named Y4 teams up with BMO. BMO convinces Y4 to embrace her own individuality, prompting her to rename herself "Y5", and also helps her realise that her parents are being misled by Hugo and Mr. M. As a team, BMO, Y5, and Olive discover Hugo's malevolent plan. With the help of the station's inhabitants, the plan is foiled, and the Unity Pod is left drifting powerless in space with Hugo stranded on board. The people of the Drift, including the formerly human grey elves, begin working together to conserve their remaining resources and repair their broken home. [BMO]

BMO rides a space lard back to Earth, where he crashes down in the Land of Ooo near Finn and Jake's Tree Fort. Finn and Jake adopt the little robot into their household, and he becomes their close friend. [BMO]

non-canon information
According to one account, BMO has an uptime of thirteen years in 998 AMB, meaning he must have undergone a reboot in about 985 AMB. This might explain why he appears to have no memory of Moe by the time he is living with Finn and Jake. He gets his supply of fresh batteries from an old pre-war electronics shop near the Tree Fort. [Adventure Time #13, Adventure Time #56]

Martin finds himself drifting alone through space, but is somehow rescued. At some point following this, he commits a cosmic crime; a crime so great that even the Cosmic Entities take issue. 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. [Escape from the Citadel]

THE PRESENT

It's Adventure Time! This section covers the show's present day, spanning the five years from 996 AMB to 1001 AMB, when Finn is between twelve and seventeen years old.

996 AMB / 3006 CE

Finn the Hero

Jake gives up his life of crime so that he and Finn can pursue a career of adventuring and heroism. At some point, Finn obtains a golden sword named Scarlet and 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?!!, Tree Trunks, The Jiggler, Ocean of Fear]

Finn writes Princess Bubblegum a birthday card in around 995 AMB, meaning she must have met Finn and Jake sometime prior to this. [The Creeps]

non-canon information
However, according to one account, Finn and Jake first meet Princess Bubblegum in 996 AMB after rescuing her from kidnap by the Ice King. Finn calls himself "Pen" at this time, apparently because he loves pens so much. [Adventure Time pilot, Adventure Time #9]

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 retrieve the book from Mannish Man. [The Enchiridion!]

Following this, Finn and Jake become protectors of the Candy Kingdom and each eventually gain the title of champion. They have frequent clashes with the Ice King, who becomes their main enemy due to his unhealthy habit for kidnapping princesses. Finn develops an unrequited crush on Princess Bubblegum. The status quo is established. [Prisoners of Love, Ricardio the Heart Guy, Hot Diggity Doom]

Finn hardly ever reads the Enchiridion, but he does use it at least once. He finds out about the cyclops and its healing tears by reading the book, and subsequently goes on to decapitate it and obtain the tears to heal his and Jake's injuries so that they can get rid of the creepy clown nurses who Jake has hired. [Another Way, In Your Footsteps]

Finn and Jake come across the zombified businessmen who were frozen following the Great Mushroom War and attempt to employ them, but order them to re-freeze themselves after their intentions become malevolent. They also visit the Grand Hall of Wizardry, which by this time is being led by a wizard named Bufo, and learn to use a selection of magic powers. Finn helps end the burden of the Ultimate Wizards by using his new powers to move the hall out of the path of the impending asteroid. Finn and Jake appear to lose their magic powers after returning home. [Business Time, Wizard]

Some of Finn and Jake's other heroic deeds from this time include returning a lost creature named the Jiggler to its mother, saving a Mountain Man from having to watch a group of rough-housing marauders, attempting to rehabilitate a jerky grass ogre named Donny, retrieving the Armor of Zeldron, helping a giant slug find love, defeating a group of evil baby pigs, bringing peace to the pagelings and the moldos who inhabit Turtle Princess' library, helping a pair of carnivorous spiders to resolve their marriage, curing Prince Huge's frog curse, rescuing a squirrel from the cultists who inhabit a tree, and slaying the Tree of Blight. During the latter, Finn temporarily becomes a hug wolf; a kind of werewolf which hugs people. He manages to cure himself of the affliction. [The Jiggler, Memories of Boom Boom Mountain, Donny, Blood Under the Skin, Slow Love, The Pods, Paper Pete, Web Weirdos, The Hard Easy, Up a Tree, Hug Wolf]

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. [His Hero]

996 AMB to 997 AMB / 3006 CE to 3007 CE

Jake's New Life

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 Rainicorn and his relationship with Finn proves to be challenging for him. [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, the former member of his old criminal gang, 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. [My Two Favorite People, One Last Job]

Jake meets Lady Rainicorn's parents at one point. He fears that prejudice left over from the Rainicorn-Dog Wars might negatively affect their relationship, but learns his worries are unfounded after Bob tells him the story of how a dog saved his life during the war. [Her Parents]

Jake struggles to hide his former criminality from Finn. The two of them visit the City of Thieves to help a girl named Penny to retrieve her stolen flower basket from the king's tower, and 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 tower, even though the actual reason is due to his criminal past. Penny reveals that she was only using Finn's innocence to break into the tower and steal its treasures for herself. Jake also accidentally steals doughnuts from a witch named Flaradulcina, for which she temporarily takes away his shape-shifting powers. Another time, when Finn and Jake are trying to track down a gold-stealing monster named the Gut Grinder, Jake convinces himself that he is the thieving monster, even though it actually turns out to be the wife of the mayor of Spiky Village. Jake also remains bitter about his defeat at the hands of Grand Prix, leading BMO to refuse to play Card Wars with him. [City of Thieves, The Witch's Garden, The Enchiridion & Marcy's Super Secret Scrapbook, Gut Grinder, Card Wars]

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 taken away from him by Flaradulcina he is completely unmotivated and can't be bothered to do anything about it, only returning to apologise to the witch after Finn finds himself in mortal peril and needs saving. Finn claims that Jake always messes up his plans, so when they get trapped in the Fight King's arena he doesn't tell Jake what his plan is for escape. [Power Animal, The Witch's Garden, Morituri Te Salutamus]

Jake's relaxed attitude also causes him to be quite accepting of his own mortality at this time. For example, he is willing to risk his life by overexerting his stretchy powers to get to the wishes at the centre of a labyrinth, so that he and Finn can wish for an Ancient Psychic Tandem War Elephant; a mysterious war machine from ancient times. Finn claims his wish from Aquandrius, the keeper of the labyrinth, and wishes the APTWE into existence, who then uses his power to restore Jake's health. After escaping the labyrinth, Finn and Jake are neglectful of APTWE and seem to forget that he exists until they find him in their treasure room while clearing it out. [The Limit, Furniture & Meat]

Jake is shown to put other people's lives ahead of his own, such as when he refuses to murder Wildberry Princess even though he knows that the assassin Me-Mow will poison him if he doesn't. Thankfully, he is able to use his powers to fight off Me-Mow's poison. [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 an introverted neighbour of theirs, 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. Jake puts his acquiescent attitude aside, and the prophecy remains to be fulfilled another day... [The New Frontier]

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. He goes to live in the roots of the Tree Fort, where he defeats the Rat King. Without the Rat King's evil influence, the Tree Fort blossoms for the first time in many years. [Little Brother]

Once a month, Jake's tail independently takes part in a bug circus, as a clown named Blue Nose. Blue Nose quits the circus after helping their captured chipmunk to escape. [Sad Face]

Finn and Jake have a few ups and downs, as any relationship does, but they remain close friends and loyal brothers through it all. When Jake gets sick, Finn goes on a long and arduous quest just to find a story to make him feel better. And when the two of them are trapped inside due to a (possibly imaginary) knife storm, they spend their time having an imaginary adventure together. [Video Makers, Who Would Win, Jake Suit, Storytelling, Rainy Day Daydream]

Jake's love for Finn and Lady Rainicorn is perhaps matched only by his love for food. His powers enable him to eat vast quantities without suffering from the ill effects of over-eating. He once makes an "everything burrito" by wrapping every food item in the house (and several non-food items) in a burrito bun. It is stolen by the Cute King, and Jake buries the burrito in a grave outside the Tree Fort after believing the cuties poisoned it. Finn and Jake repel and defeat the Cute King's incredibly weak "army". Jake's most famous dish is undoubtedly his legendary bacon pancakes. Jake claims he cannot eat chocolate or fudge, yet is also seen consuming huge amounts of chocolate ice cream at one point. [Conquest of Cuteness, Burning Low, Slumber Party Panic, The Pods]

996 AMB / 3006 CE

Marceline's Reunion

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. [Evicted!, It Came from the Nightosphere]

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 for fun. Jake takes a little while longer to warm up to her due to his pre-existing fear of vampires, and even tries to slay her when he thinks she is controlling Finn's mind, but he eventually befriends her too. Marceline saves Finn and Jake's lives when her old ghost gang-mates, Wendy, Booboo, and Georgie, try to kill them. [Henchman, 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. [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 nearly 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, their father-daughter relationship begins to improve. [It Came from the Nightosphere]

996 AMB to 997 AMB / 3006 CE to 3007 CE

Princess Bubblegum

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, and an 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. [Slumber Party Panic, From Bad to Worse, What Have You Done?, No One Can Hear You]

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 offer to give her his own long and beautiful hair, and she releases Jake. Finn gets to keep the wad of Princess Bubblegum's hair, and it becomes his most treasured possession. [To Cut a Woman's Hair, What Was Missing]

Bubblegum, meanwhile, usually treats Finn with friendly professionalism. She often sends Finn and Jake off to do errands for the Candy Kingdom, such as signposting a dangerous dungeon, hauling the Royal Tarts to the annual Back-Rubbing Ceremony, and (unsuccessfully) looking after her plant. During the latter, Finn and Jake end up getting help from Peppermint Butler in order to travel to the Land of the Dead and rescue the soul of the plant. Death allows them to take the plant soul thanks to his friendship with Peppermint Butler. [Dungeon, The Other Tarts, Death in Bloom]

Princess Bubblegum makes an enemy of the Duke of Nuts after he begins stealing pudding from the Candy Kingdom to sate his "pudding deficiency", and she orders Finn and Jake to arrest him, but they refuse after learning he's actually a good person. The Duchy of Nuts eventually improves its relations with the Candy Kingdom, and the two become allies. [The Duke, Come Along With Me]

One of Finn's main shortcomings when it comes to courting the princess is his inability to match her intellect. Finn obtains the Glasses of Nerdicon from Choose Goose to make himself super-intelligent in order to impress her, and one of the few times she ever kisses him is after he uses his super-intelligence to open a black hole at her scientific conference. Finn loses the glasses after they fall into the black hole, and also loses his golden sword while closing it. Another time, Princess Bubblegum offered a kiss as the grand prize of a contest called Wizard Battle. Finn ends up winning the competition's prize in order to "save" Bubblegum from being kissed by the Ice King, or by another wizard contestant named Abracadaniel. [Ricardio the Heart Guy, The Real You, Wizard Battle]

Finn gets a new sword named the Root Sword on his thirteenth birthday, which he finds during a fake murder mystery that was set up for him by Jake. He begins using it in place of his lost golden sword. [Mystery Train]

note
"Root Sword" was a name invented by fans, but it was later made canon by The Enchiridion & Marcy's Super Secret Scrapbook.

Meanwhile, Princess Bubblegum's relationship with Marceline has remained sour ever since their breakup. Bubblegum usually does her best to ignore Marceline, so Marceline often deliberately tries to get on her nerves. However, the two still secretly care about each other. Marceline sabotages Finn's attempts to ask Bubblegum on a date, and Bubblegum still has the rock shirt. [Obsidian, Go With Me, What Was Missing]

996 AMB to 998 AMB / 3006 CE to 3008 CE

The Misunderstood Ice King

Simon Petrikov, now completely fallen to the insanity of Evergreen's crown, has become known as the Ice King to everyone but Marceline. 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. Princess Bubblegum is one of his most frequent victims. [Prisoners of Love, Ricardio the Heart Guy]

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. At one point he steals body parts from various princesses to build himself a new wife, but after finding out her own gruesome origin even his own creation refuses to stay married to him. [When Wedding Bells Thaw, Loyalty to the King, The Chamber of Frozen Blades, Wizard Battle, Princess Monster Wife]

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 better. Unfortunately his methods for doing so are usually unintentionally creepy or malevolent, such as disguising himself as a horse and watching Finn and Jake sleep, accidentally hiring an assassin to kill them, using a potion to paralyse them just so that he can spend time with them, and refusing to tell Finn how to escape the Spirit World so that he would be the only person Finn can talk to. But ultimately he has no intention to harm anyone. [The Eyes, Hitman, Still, Beyond This Earthly Realm]

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. [The Chamber of Frozen Blades, Reign of Gunters]

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 magical lightning power. Neptr is left with two father figures: Finn, his creator, and Ice King, who imbues him with the energy he needs to become fully operational. However, he is ultimately neglected by both of them. He lives in the Tree Fort with Finn, Jake, and BMO. [What is Life?, Hot to the Touch, Mystery Dungeon]

Another of Ice King's creations is Ricardio, who is created when Ice King accidentally brings his own heart to life. Ricardio escapes Ice King's body and tries to cut out Princess Bubblegum's heart so he can make out with it, but he is defeated by Finn and Jake and returned to the Ice King for now. [Ricardio the Heart Guy]

One day, Finn and Jake discover Ice King's "secret tapes". Most of them are random diaries and home videos taken by the Ice King, but among them are the tapes created by Simon Petrikov a thousand years ago, recording his spiralling descent into madness. Having learned of Ice King's tragic past, Finn and Jake come to see him in a new light, and he begins to become an ally and a friend to them. To commemorate the event, Finn, Jake, and Ice King establish an annual winter tradition of friendship and gift-giving, inadvertently restoring the lost pre-war celebration known as Christmas. [Holly Jolly Secrets Part I, Holly Jolly Secrets Part II]

Somewhere in the Ice Kingdom, a snow golem befriends a fire wolf. [Thank You]

997 AMB / 3007 CE

Fionna and Cake

The heroic antics of Finn and Jake are an inspiration to Prismo the Wishmaster. After eons of granting wishes and creating new wish-altered dimensions for the visitors to his Time Room, Prismo desires to create one all of his own. He envisions and creates a universe much like the Land of Ooo, but where everyone's gender has been swapped. He dubs his creation "Fionna and Cake", and his own branch of the Multiverse is born. However, this action is very strictly against the rules. The characters resulting from such a universe are a danger to the stability of the rest of the Multiverse. To hide his creation from the audit, Prismo places the universe in a hidden place; the cursed, mostly empty, and highly receptive brain of the Ice King. Details of Fionna and Cake are beamed from the Time Room into Ice King's mind while he sleeps, until an entire universe is packed within his mind. [Prismo the Wishmaster, Fionna and Cake and Fionna]

Ice King is not aware of the true weight of what he carries in his brain, but aspects of Fionna and Cake make it to his conscious mind in the form of dreams and ideas. He writes them down, and they quickly become a vast collection of "fan fiction". Ice King eventually becomes so obsessed with his stories that he refuses to allow them to be criticised, and desperately wants to join Fionna and Cake in their universe. He sends some of his stories to the Ble Magazine, without realising that production of the magazine shut down at least five hundred years prior. [Fionna and Cake, Bad Little Boy, Five Short Tables, Blenanas]

Cake the Cat and Fionna the Human are the gender-swapped counterparts to Jake the Dog and Finn the Human. Just like Finn and Jake, they live in the Tree Fort with BMO. The ruler of the Candy Kingdom is Prince Gumball, and they have a devious and unpredictable vampire acquaintance named Marshall Lee. Their main nemesis is the Ice Queen. The first story that Ice King writes involves Fionna going on a date with Prince Gumball, who turns out to be the Ice Queen in disguise. [Fionna and Cake]

As the Fionna and Cake canon grows, other people in Ice King's life begin making contributions, although these may or may not be part of the true Fionna and Cake universe. Gunter dreams up an origin story for the Ice Queen, in which she was a water nymph who was made immortal against her will, and began kidnapping princes in a futile attempt to thaw her frozen heart with the warmth of true love. Gunter also dreams of Flame Prince, whom Fionna rescues from the Ice Queen. In a story recited by Marceline, her counterpart Marshall Lee takes a joke too far by pretending to get staked, and Fionna makes it clear she's not romantically interested in him. Lumpy Space Princess writes a story about her own counterpart character learning not to care about parental disapproval. [Fionna and Cake #1 to #6, Bad Little Boy, The Prince Who Wanted Everything]

Inexplicably, there is also somehow at least one taped "episode" of Fionna and Cake loose in the Land of Ooo, featuring the Queen of Ooo. [Fionna and Cake and Fionna]

996 AMB to 1000 AMB / 3006 CE to 3010 CE

Drama in Lumpy Space

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. She introduces them to her home dimension to retrieve a special antidote after infecting Jake with "the Lumps", a condition that turns infected individuals into melodramatic Lumpy Space people. Finn and LSP manage to cure Jake. [Trouble in Lumpy Space]

After her quinceañera, 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. She usually camps in the woods eating beans or fighting wild animals for pieces of discarded fried chicken, but also spends some of her time living in the Candy Kingdom's Coolest Hotel. During one stay at the hotel, she leads Finn and Jake on a wild goose chase around the Candy Kingdom, during which they wrongfully convict a candy person named Pete Sassafras. LSP periodically returns home to seek food and shelter at her parents' house. She is briefly adopted by a pack of wolves before they turn against her. After that she 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 in the Land of Ooo. [The Eyes, To Cut a Woman's Hair, Heat Signature, Be Sweet, Candy Streets, The Monster]

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. Turtle Princess convinces her to write a trashy women's advice book, and she later also writes a story taking place in Ice King's Fionna and Cake universe. One of her most notable nemeses is Breakfast Princess, who accuses her of not being a "real princess" since she is only an heir, and not a ruler. [Gotcha!, The Prince Who Wanted Everything, Princess Day]

In 999 AMB when LSP is about eighteen years old, Johnnie, 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. Johnnie happens to meet LSP in a bar and she ends up falling in love with him. For the early part of the relationship she acts uncharacteristically mature and seems to genuinely enjoy being with him. [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 Johnnie 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 Johnnie has never been saved in the bubble, attempting to load a previous state simply deletes him from existence. Bubblegum then offers to use the time machine to remove LSP's memories of the whole ordeal. Johnnie is lost forever, and LSP doesn't remember a thing. [Bad Timing]

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, slowly coming to realise her own flaws. By spending time with Finn, she realises that beauty can be on the inside, rather than just the outside. She begins to doubt her own assumed righteousness after crashing Princess Day at the Breakfast Kingdom and losing a child she was supposed to be babysitting, and she begins to believe that her constant bad luck is what she deserves for being a bad person. [Skyhooks II, Gotcha!, Princess Day, Be Sweet]

She keeps these feelings hidden away from other people. In an attempt to demonstrate to the world that she isn't just a shallow brat, she pursues playwriting, and in 1000 AMB she writes a play titled Summer Showers set in pre-apocalyptic England. [Summer Showers]

---

996 AMB to 997 AMB / 3006 CE to 3007 CE

Susan Strong

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. Since she has forgotten her own name, Finn and Jake name her "Susan" after she fails to pronounce the word "Sun". She becomes known as Susan Strong, coincidentally retaining her original surname. [Susan Strong, Hide and Seek]

After conquering their fear of the outside world, Susan and 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. [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. [Beautopia]

From that point on, the hyoomans continue to thrive in their underground home. Susan and her friends end up destroying the Super Porp Factory after the company's automated systems kidnap a hyooman baby, ending the production of the ancient drink. [Dark Purple]

997 AMB / 3007 CE

The Lich Returns

One day, Princess Bubblegum has a vision of The Lich while meditating. She takes Finn and Jake to see the amber prison in the top of Neddy's tree where he is being held. While Bubblegum, Finn, and Jake are all protected from The Lich's telepathic powers by Bubblegum's Gems of Power, he is able to possess a snail that was riding on Finn's backpack. The snail cracks the amber, and to Bubblegum's horror, The Lich seeps through the crack and escapes into the world. 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. [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. The Lich's physical form is destroyed. All appears to be resolved until Ice King accidentally drops the princess into the well. With his wizard eyes, Ice King sees the spirit of The Lich enter Princess Bubblegum. [Mortal Folly, Mortal Recoil]

Princess Bubblegum is rushed back to the Candy Kingdom, where she 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 by shattering her possessed body into many pieces. 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. [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. [Too Young]

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. [Too Young]

---

997 AMB / 3007 CE

Finn, Marceline, and Bubblegum

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 fries incident, and when she moved into the Tree Fort. [Memory of a Memory]

non-canon information
Ash is later arrested for fencing stolen property, impersonation, memory stealing, and "being a general pain in the butt". [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 when they first fell in love all those hundreds of years ago 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 following this. [What Was Missing, Obsidian]

The items stolen from Jake and BMO were Jake's blanket and BMO's controller. 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 Was Missing]

The friends subsequently often meet up for further jam sessions where they practice their music together. During one of these, Finn and Jake end up accidentally hiding in Marceline's bedroom while playing a variation of hide and seek called Cloud Hunt. They see and hear a lot of things they shouldn't have, but their friendship with Marceline remains undamaged as she reveals she hides in their house all the time too. [Marceline's Closet, Daddy's Little Monster]

Clarence and Ghost Princess

Clarence, the man who accidentally killed Warrior Princess, has become depressed and resorts to overeating. He dies from 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]

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 Deadworld together. [Ghost Princess]

non-canon information
One account states that Ghost Princess was brought back from the Fiftieth Deadworld by the Ice King under the false impression that his romance would "make her feel alive again". [Marcy & Simon #1]

Joshua's Dungeon

Finn and Jake discover the holo-message player left in their attic by Joshua 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. [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. [Dad's Dungeon]

998 AMB / 3008 CE

Finn and Flame Princess

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. He has a flambit named Flambo cast a flame shield spell on him so that he can resist the intense temperatures of the kingdom. 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. [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. [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, against Bubblegum's advice, makes no effort to prevent Finn and Flame Princess from seeing each other. [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. Finn and Jake also foil an attempt on her father's life by Furnius and Torcho, his betrayed nephew and niece. [Burning Low, Ignition Point]

non-canon information
According to one account, Finn and Flame Princess figure out how to hug and kiss without hurting each other. They visit the Carnival Kingdom together, and Flame Princess and Jake end up having to save Finn's soul from a misguided fortune teller. [Playing With Fire]

Journey to the Nightosphere

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. [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. 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. [Return to the Nightosphere, 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. [Daddy's Little Monster]

It is not known whether or not the political uprising in the Nightosphere was successful. [Daddy's Little Monster]

998 AMB / 3008 CE

Bubblegum's Malevolence

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 whom 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. [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. [Goliad, 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]

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. [You Made Me, Lady & Peebles, 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 disposable playthings rather than as people. Her reliance on cloning numbs her to the tragedy of individual deaths, since she is always able to create a brand new clone who looks and acts in almost the exact same way as the lost subject. [The Lich, James]

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. During her breakout, Princess Bubblegum discovers that her own magical abilities are far more powerful than she realised. Although she does not know it at the time, this is due to her true nature as the Candy Elemental. [Wizards Only Fools, Elemental]

One day, 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]

Magic Man's Trial

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. [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. [Sons of Mars]

Ashamed by his poor judgement, Lincoln travels to the Thirty-Seventh Deadworld to retrieve Jake from Death. But Death is not willing to return a life for nothing. [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. [Sons of Mars]

Magic Man crosses paths with Finn and Jake several more times, mostly with the intention of making their lives miserable. He steals a "perfect sandwich" that Jake had made, and forces them to solve a riddle in order to retrieve it. He also poisons Jake with a strange serum which causes him to shape-shift an entire fabricated civilisation within his own body, similar to the home planet of Jake's father Warren Ampersand. This tiny world is destroyed after Jake is forced to return to the outside world, because otherwise he would have starved to death. The event leaves Jake mildly traumatised. [Time Sandwich, Everything's Jake]

998 AMB / 3008 CE

The Lich's Wish

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. [In Your Footsteps]

Finn sees a premonition of things to come while in a dream induced by a malevolent being named King Worm. By confronting his fears, Finn is able to destroy his dreamscape and kick King Worm out of his mind, consequently defeating him in the real world too. [King Worm]

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. [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 dimension where that wish has come true. In a single instant, all the flesh is rent from every living thing in the Land of Ooo, leaving nothing but skeletons and the dead husks of what were once plants. [Finn the Human, Jerry]

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 dimension, known as Farmworld. [Finn the Human]

In Farmworld, 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. [Finn the Human]

By 984 AMB, Farmworld 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. 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. [Finn the Human, 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 all life. [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. Both Farmworld and the Lich's wish-altered reality continue to exist, but they are safely contained within their own dimensions like all the other branches of the Multiverse. 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 knelt in Prismo's room like a statue, patiently waiting for his next opportunity. [Jake the Dog, Crossover, Jerry, 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. [Jake the Dog]

998 AMB / 3008 CE

The Birth of the Pups

At some point, Jake and Lady Rainicorn have a very good time on the swan ride at a theme park named Thrashland. [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. [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. [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. [Ocarina]

All of the pups go on to establish their own unique lives, and each develop unique powers derived from the abilities of their parents. They all seem to share the basic powers of teleportation and re-colourisation, and most of them can fly. [Jake the Dad]

Jake Junior reunites Jake's old criminal gang (Gareth, the Flying Lettuce Brothers, and Tiffany) and tricks Jake into helping them steal the Bakers' Shard from the Royal Candy Vault, in a misguided attempt to impress him by coming up with her own criminal scheme. The other gang members escape after Jake uncovers the plot. Jake Junior has the unique ability to shape-shift her hair, but apparently not the rest of her body. [One Last Job, Another Five More Short Graybles]

Kim Kil Whan founds a real estate business named K.K.W. Enterprises. He settles down with his wife (a bear named Pat) and they have a daughter named Bronwyn; Jake's first grandchild. Kil Whan temporarily buys the deed to the Tree Fort from Marceline and forces Finn and Jake to share their home with several other tenants. They are unable to buy the property back from him because they had recently spent all of their treasure in Wildberry Kingdom. His intention was to force Jake to mature and get a job, but his plan fails and he eventually just gives the deed to his father, accepting that he will not change his ways and deciding that that's okay. Legal ownership of the Tree Fort is finally transferred to Finn and Jake. Kim Kil Whan also claims ownership of his grandparents' old office, where his father Jake was born. [Ocarina, Furniture & Meat, The First Investigation]

Kil Whan's daughter Bronwyn embraces a teenage lifestyle, to the distress of her father, and often sneaks out at night to go skateboarding with her friends rather than studying. She has the unique ability to summon lightning. [Wheels]

T.V. continues living with his mother well into adulthood, spending most of his time on his computer. He has issues distinguishing fantasy from reality, which leads to him forming a deep connection with the diary of Nurse Betsy Pound Cake. He can use this connection to divine missing details from the incomplete text, which might be his unique power. After accidentally eating the Crystal Mergence of Destruction, he is kidnapped to the Crystal Dimension by his mother's ex-boyfriend, Lee, and has to be rescued by his mother. He announces that he wants to remain in the Crystal Dimension so that he can be more independent, but just ends up living with his grandparents Bob and Ethel. Eventually, however, he acquires the old office of Joshua and Margaret Investigations from his brother Kim Kil Whan, and begins his own private investigation business. [Jake Suit, The Diary, Lady Rainicorn of the Crystal Dimension, Come Along With Me]

Viola dreams of being an actress. Her first big part is in Summer Showers, the play written by LSP. Viola is actually a last minute replacement after Tree Trunks has to drop out of the play. [Summer Showers]

non-canon information
According to one account, Viola takes a college admission test just three days after being born, although it's unknown whether or not she is accepted. [Adventure Time #44: "Tiger and the Moon"]

Charlie develops a skill for divination via tarot reading. Her special power allows her to grow into an enormous but incorporeal form, large enough to cross continents in just a few strides. She does most of her divination in one of the pyramids of Ancient Egypt; one of the few characters known to regularly travel to other parts of Planet Earth. She joins her father for the fifty-ninth Card Wars Doubles Classic and helps him get to the finals, although they lose in the final round against the reigning champions Grand Prix and Moniker. [Daddy-Daughter Card Wars]

Although it will not become apparent for a while, the pups' overpowered abilities and incredibly fast ageing process put them on the path towards becoming the dominant species in Ooo. [Come Along With Me]

non-canon information
Each pup is later assigned a unique number depending on their order of birth. Jake and Lady's original children are assigned the numbers one through five, and Bronwyn is assigned the number six. Each pup is also confirmed to have their own unique pup power, some of which are so extreme that they have been described as "walking nukes". [Steve Wolfhard (1) (2) (3)]

996 AMB to 998 AMB / 3006 CE to 3008 CE

Xergiok, The Great Bird Man

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 a golem named Whisper Dan as a placeholder and leave the goblins to rule themselves. [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 a mountainous complex called the Rookery where he looks after his giant birds and becomes known amongst the people of Ooo as the legendary "Great Bird Man". As a changed man, Xergiok puts other people ahead of himself, even donating his kidneys to a hospital. [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. [The Great Bird Man]

---

999 AMB / 3009 CE

The Breakup

Over time, Finn begins to develop something of a arrogant streak 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 using an unremarkable alter ego named Davey for a while. [All the Little People, Davey]

non-canon information
Finn's disguise happens to look identical to a real human named Davey who, according to one account, was a reincarnation of the Blue Catalyst Comet and therefore a previous life of Finn. [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 insistence towards 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. [Vault of Bones, Puhoy]

It is at this time Finn travels into "Pillow World", a possibly imaginary alternate timeline. Finn becomes hero of a town in Pillow World 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. One day, 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. By now an elderly man, Finn visits Rasheeta the Oracle. She merely tells him that there is "not long now" until he will be able to return home. [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 and is pulled back into the real world. On the way, he has a close encounter with GOLB, and narrowly avoids being removed from existence. It would appear that the rest of Pillow World is not so lucky. Despite Roselinen's wish, Finn immediately forgets everything about his life in Pillow World and continues living his regular life as if nothing ever happened. [Puhoy]

non-canon information
According to one account, Pillow World is a real dimension, rather than a place imagined by Finn or a reality that was erased by GOLB. However, its depiction in this account is very inconsistent with its original depiction. For example, Finn is said to remember its existence, and the characters who visit it age rapidly for some reason. [Marcy & Simon #5]

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. [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. [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. [Frost & Fire, Too Old, Earth & Water]

---

999 AMB / 3009 CE

A Game of Thrones

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. [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. [Earth & Water]

Finn is also feeling lost after the end of his first real romantic relationship, falling into a bit of a depression. [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. [Dungeon Train, Box Prince, Too Old, The Vault, Rattleballs]

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. [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 weakened, by having her servant Ursula poison her, and succeeds in returning the Red Throne to Flame King by hypnotising the guards and the royal court. Flame Princess chooses to go to Finn for help on strictly platonic terms. [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. [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. [Furniture & Meat, Princess Day]

Finn's Vault

As previously mentioned, Jake set up a fake murder mystery on a train for Finn's thirteenth birthday. Later that same year, Finn tries to pull a similar stunt in return. 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. [Mystery Train, The Creeps]

non-canon information
According to one account, Finn set up the mansion murder mystery to coincide with Jake's own birthday. [Righteous Rules for Being Awesome]

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". [The Creeps, The Vault]

About two years later, in 999 AMB, 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 blue amulet to Princess Bubblegum. Finn digs Shoko's corpse out from under the floorboards of the Tree Fort and gives the amulet back to Bubblegum, allowing Shoko to move on in peace and ending the nightmares. [The Vault]

999 AMB / 3009 CE

Kee-Oth Returns

After getting tired of letting Ice King live 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. [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. [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. [The Pit]

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, who is a priest, 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. [The Pit]

The Chronicles of James

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. Princess Bubblegum develops a "decorpsinator serum" following the two zombie invasions, which can bring candy people back from the dead. Additionally, the Spoon of Prosperity, an item which can magically satisfy any hunger, 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. [Root Beer Guy, Candy Streets, Summer Showers, Slumber Party Panic, Red Starved]

Princess Bubblegum even begins development of a space program, and Finn and Jake's neighbour Banana Man also continues to work on his own rocket ship. Finn and Jake befriend Banana Man after he helps them refurbish a pre-war truck. He later accompanies them to solve the leadership crisis that followed the disappearance of President Porpoise, during which he falls in love with a representative of the Fish Parliament named Cybil, finally overcoming his loneliness. [The Comet, We Fixed a Truck, President Porpoise is Missing!]

The Candy Kingdom seeks to further expand its territory into new unexplored areas; notably, the Desert of Wonders, a condemned area of pre-war ruins which has been left mostly untouched since the Great Mushroom War. Princess Bubblegum 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. The clone is awarded a medal for bravery, despite not sharing the memories of the original James. [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. [James II, Jake the Brick]

996 AMB to 999 AMB / 3006 CE to 3009 CE

Tree Trunks and Mr. Pig

By 996 AMB, 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. [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". [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. [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 warned off the trail by a gang of criminals outside the Candy Tavern. They track the criminals back to their hideout where they get captured and finally realise that "apples" is slang for "diamonds" and their entire escapade has been pointless. They rescue a pig (named Mr. Pig) from the gang while they are escaping, who notices that Tree Trunks' apples were actually being stolen by birds due to the fact that Raggedy Princess was no longer acting as her scarecrow. [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. [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. [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 will not be the last the kingdom sees of him. [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. [Apple Wedding, High Strangeness]

The Grass Sword

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. [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 the gumball that had 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. [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. [Rattleballs]

999 AMB / 3009 CE

Betty's Arrival

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. [I Remember You, Simon & Marcy, Bad Little Boy]

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. Since Marceline and Bubblegum are once again friends by this point, it's possible that Bubblegum no longer felt like she needed to hold onto the shirt to remain attached to Marceline. The shirt holds a vastly greater sentimental value even than Hambo; power which Maja uses to begin to enact her plan. But that's a story for later. [Sky Witch]

A secret society in Wizard City makes a deal with an evil interdimensional anti-magical creature named Bella 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. [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 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. [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 Bella Noche's lights out and restores magic to the city. The crown re-activates, and Simon becomes the Ice King once again. [Betty]

Seeing how he has been driven to insanity, Betty remains incognito and studies Ice King from a distance, but still spends all her time trying to find a cure for his condition. [You Forgot Your Floaties]

998 AMB to 999 AMB / 3008 CE to 3009 CE

A Tale of Two Lemons

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. [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. [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. [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. [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 and confined to a hover-chair, unable to counteract the increasingly tyrannical rule of his brother. [Another Five More Short Graybles, 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 Lemongrab Number One forbids it. Lemongrab Number Two takes some pity on the child and tries to help him escape. This pushes Number One over the scales, and in a rage he consumes his twin brother whole. [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 Lemongrab Number One 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, and eventually runs away from the kingdom on a quest for true freedom. [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 sand-ship. But the ship is attacked by a greed lard; all of the crew go missing in the battle, and the ship is stranded in the middle of the 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. [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. [Lemonhope Part Two]

Lemonhope decides that he will make it his mission to defeat Lemongrab Number One, 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 Number One to explode. Both Lemongrabs are ripped apart in the blast, and the earldom is liberated from Number One's tyranny. [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. [Lemonhope Part Two]

The new Earl of Lemongrab begins structuring the earldom into a slightly better place. However, he is left feeling as though something is missing from his life. He considers amalgamating with a collective consciousness known as Matthew, whose purpose is to restore balance after the Second Age of Terror; the prophesied destruction of the world at the hands of Coconteppi. Joining Matthew would destroy Lemongrab's own ego and allow him to become one with something greater than himself. But instead, he decides to overcome his fear of incompletion by destroying Matthew and releasing all those who have amalgamated with him through history. At last, Lemongrab appears to be a little more at peace with his own existence. [The Mountain, Wizard City]

999 AMB / 3009 CE

The Death of Prismo

In 997 AMB, Finn and Jake rescue a sleuth of party bears from being digested in the belly of a monster. Some time later, one of the rescued bears, named Rap Bear, challenges Finn to a rap battle in the Candy Kingdom. After the battle, Finn meets Billy's ex-girlfriend Canyon. Together, Finn and Canyon 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. [Belly of the Beast, Billy's Bucket List]

Jake has previously attempted to help Finn overcome his fear of the ocean, but to no avail. The Fear Feaster appears to be an unshakable part of Finn. However, Finn is determined to honour Billy, so he deliberately 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 using his cursed blade and suddenly finds that his fear is gone. Having completed the bucket list, Finn experiences a vision of Billy, who tells him that his real human father, Martin Mertens, is at the Citadel. [Ocean of Fear, 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. [Wake Up]

After Jake hears about Finn's father being in the Citadel, he suggests going to Prismo for advice. Prismo tells them that the Citadel is a prison for the worst of the worst, and that the only way to get there is to commit a cosmic crime. One such crime would be to murder a wishmaster such as himself. He tells them that they can temporarily "kill" him by waking up the mysterious old man who dreams of his existence. [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. [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. [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. [Escape from the Citadel]

Finn grabs Martin's vehicle 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. [Escape from the Citadel]

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. [Escape from the Citadel]

999 AMB / 3009 CE

Martin, Breezy, and the Arm

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 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. [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 despite his status as its champion. [The Tower, 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. He meets a virgin queen bee named Breezy, who falls in love with Finn's flower and tries to help him save it. She becomes a true queen to save Finn from a group of thugs, and realises that she is not just in love with Finn's flower, but also with Finn himself. But Finn does not reciprocate her feelings. That night, Breezy sings a song to Finn while he is asleep, and he subconsciously joins in harmony. From his stump grows a huge tree branch, which splits to reveal a fully reformed arm. Within this new arm is a thorn, still containing the spirit of the Grass Sword's curse. Breezy keeps the flower. [Breezy]

Ice King and Friends

After a thousand years of loneliness, Ice King finally manages to maintain some relationships beyond kidnapped princesses. His emotional maturity improves, especially when he takes off his crown. Some of the princesses make efforts to include him in social events like the princess potluck to encourage his rehabilitation. Finn and Jake also attend the potluck and win a pet sea lard, which they have to rescue from the mysterious world below the nymphs' grotto in the pond outside the Tree Fort. At one point Ice King befriends an Island Lady and convinces her to break up with Party God, her frequently absent boyfriend. [The Party's Over Isla de Señorita, Princess Potluck, Beyond the Grotto]

As previously discussed, Ice King's 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. [Wizard Battle, Play Date]

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. 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. Life-Giving Magus is thirty-seven years old in 1000 AMB, meaning he was born in 963 AMB, unless his time spent in the dungeon halted his ageing process. [Mystery Dungeon, Little Dude, Ice King #4]

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 and just brings the physical Fionna and Cake book to life instead. Life-Giving Magus also 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 Life-Giving Magus is able to turn him good. The hat becomes known as Little Dude, and he and his creator befriend the Ice King. [Mystery Dungeon, Little Dude, Thanks for the Crabapples Giuseppe!]

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, Life-Giving Magus, 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 a crabapple tree as their symbol. Probably for the first time since putting on the crown, Ice King has a real group of friends. [Thanks for the Crabapples Giuseppe!, Ice King #1]

Unfortunately, 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. At one point he claims to be "done with" Abracadaniel, and also exploits Life-Giving Magus into bringing all his furniture to life, although they later reconcile. But despite his disagreeable actions, Ice King remains a member of the Order. A wizard named Alistair Blacktide joins the Order after befriending the Ice King and leaving the Dark Moon Esbats, a rival order who were attempting to find and defeat the Dark Magister Templi Marble. [Friends Forever, Ice King #6]

999 AMB to 1000 AMB / 3009 CE to 3010 CE

Root Beer Guy

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 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. [Root Beer Guy]

Meanwhile, Maja returns to the Candy Kingdom with dreams of conquest, having used the huge sentimental power of Bubblegum's shirt to raise a powerful being named Darren the Ancient Sleeper. Darren appears to have some past connection to the Ancient Psychic Tandem War Elephant, the war machine who was wished into existence by Finn and Jake, and who they had recently found to still be living in their treasure room. Root Beer Guy is killed while activating a force field to keep Darren in place. His sacrifice does not go to waste; the force field grants Finn and Jake enough time to fetch APTWE and defeat Darren before he could destroy the Candy Kingdom. Maja is put in a coma during the battle, and afterwards APTWE chooses to look after her until she wakes up. [The Limit, Furniture & Meat, Something Big]

Maja's abused crabbit familiar is finally freed from servitude and pursues his dreams of becoming a dancer. [Sky Witch, Come Along With Me]

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 this alternate timeline, 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. Dirt Beer Guy begins running the Candy Tavern. [Cherry Cream Soda, Abstract]

The area around the Candy Tavern is the stomping ground of the Marshmallow Kids, a gang who keep other criminals at bay. In return for this service they run scams outside the tavern to trick gullible candy people into giving over their life savings. Princess Bubblegum at one point hires Finn to take the gang on a field trip, in an attempt to make sure they don't become full-fledged criminals. It goes well, and the Marshmallow Kids all begin attending school. [Scamps]

999 AMB / 3009 CE

Picklerama

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 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. [Is That You?]

non-canon information
According to one account, Jake actually embezzles one more jar of Prismo's pickles and keeps them hidden under his pillow, meaning the ones used to activate Plan B weren't the last ones at all. [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 deadworld and kill a ghost fly. He begins to go through some of his own existential dilemmas and mystical journeys. Most notably, he attempts to fulfil his bizarre lifelong dream of being a brick in a brick shack when the brick shack falls down. The attempt is unsuccessful, but Jake is satisfied by the experience nonetheless. During the attempt, his commentary on the activities of a nearby bunny gains a cult following throughout Ooo after Finn has Starchy broadcast them from his radio tower. [Sons of Mars, Ghost Fly, Jake the Brick]

A man named Morty Rogers transfers a pair of parasitic curses named Chips and Ice Cream onto Jake. BMO figures out how to free Chips and Ice Cream into the world so that they no longer need to be attached to a host. [Chips and Ice Cream]

Tiffany overcomes his hatred for Finn and the two work together to complete their service, but Tiffany gets eaten by a giant worm and appears to be killed. [Dentist]

Fire and Candy

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. [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. [The Cooler]

Bubblegum begins trying to worry less about her own subjects. On one occasion she skips a slumber party to hang out with Finn, trusting her subjects to look after themselves for just a few minutes. But the candy people quickly devolve into chaos after they believe that she has died, and have a small war over who should be the new ruler of the kingdom. Crunchy wins, but he is deposed when Bubblegum returns. [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. [The Thin Yellow Line]

non-canon information
Marceline is supportive of Bubblegum's new attitude, encouraging her to continue dismantling the surveillance network. [Season 11 #6]

Glob's Sacrifice

A fast moving object enters the Solar System on a collision course with Mars. Despite its unusual 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. [Astral Plane]

Glob appears to perish in the collision, but actually survives. His four heads end up in orbit around the Earth. [Astral Plane, Normal Man]

In addition, the object was not actually an early Catalyst Comet but in fact a spaceship piloted by Martin Mertens. Heavily damaged in the collision with Glob, it crash lands in a small farming 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. He exploits the villagers, ignoring Finn's concerns about their health and safety, and leaves on bad terms with his son. [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. [The Visitor]

Martin continues his own adventures in space, and ends up getting imprisoned on the planet of the koala people for betting on illegal lard fights. He befriends and then betrays some of the koala rebels, stealing their giant moth and flying into space with it. He also steals a vast amount of treasure from the planet's oppressive lizard rulers. [On the Lam]

Seven and the Huge King

One day, a travelling sales-bear named Bill falls into King Huge'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 King Huge'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. [Walnuts & Rain]

Months later, while walking through the forest, Finn and Jake each fall into two different holes above King Huge's lair. Finn falls into the lair itself and is kidnapped by King Huge. 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 King Huge's lair. [Walnuts & Rain]

Jermaine and his Demons

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. [Jermaine]

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. [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. [Orb, Abstract]

Magic, Madness, and Sadness

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. [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, and with all of his magical abilities lost, he renames himself "Normal Man". [You Forgot Your Floaties, Normal Man]

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 ideas for saving Simon. [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. [King's Ransom]

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 VR 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 from the virus, re-establishes its defences and kicks out Marceline and Bubblegum. Ice King is returned to normal and Betty's plan has failed. [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 has finally earned the end of his banishment, and is ready to rule on his own. Glob remains in orbit around Earth and sends Normal Man to Mars. Normal Man arrives alone, and establishes himself as their new leader. [Normal Man]

1000 AMB / 3010 CE

The Election and the Comet

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 seek new sources of income. They make a lot of money by exploiting Sweet P, the adopted son of Tree Trunks and Mr. Pig who was formerly The Lich. [Gold Stars]

However, this exploitation uncovers Sweet P's hidden dark side, and he drives the thieves to near-insanity by showing them a glimpse of the monsters from before time. But again, this would not be the last the Candy Kingdom would see of the King of Ooo. Sweet P dismisses his hidden powers, believing that they are "just a dream". [Gold Stars]

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 dreamscape. He interferes and causes the dream to go bad, depicting rebellion against Princess Bubblegum and the fall of the Candy Kingdom. And since the Cosmic Owl is present, the dream becomes a prophecy and its events 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. [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, and Orgalorg begins clawing his way back towards consciousness. [Orgalorg]

Meanwhile, the Purple Catalyst Comet has begun to approach Earth. Unlike the "comet" which actually turned out to be Martin's spaceship, this one is the real deal. Sweet P and Orgalorg both begin to have dreams and visions of the impending comet. [Be Sweet, Orgalorg]

Princess Bubblegum also foresees the Purple Comet; not through a dream or a vision, but through a telescope. She understands the destruction it could potentially bring and constructs a spaceship. Her plan is presumably to redirect the comet should it end up on a collision course with her kingdom. [Hot Diggity Doom]

Having recovered from his traumatic encounter with Sweet P, the King of Ooo reveals the plan for his "big comeback". He intends to hold an election against Princess Bubblegum to have himself voted in as the new princess of the Candy Kingdom. 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. At some point Orgalorg overtakes Gunter's mind again. Believing that the election 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 a secret society named the Veritas Brigade 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. [Hot Diggity Doom, High Strangeness]

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. [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. Once the ship is in orbit they confront Orgalorg, who, finally free of the Earth's imprisoning gravity, is able to take his true form and reveal his plan. [Hot Diggity Doom, 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. With Glob apparently dead, Orgalorg has taken advantage of this second opportunity. He perceives his stowaways as little more than a minor nuisance, and throws Finn and Jake out into space where they 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 the giant 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 through space 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. The thorn inside Finn's arm 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, offering Finn a new mode of existence. [Orgalorg, On The Lam, 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 are still on Finn's side. Jake's prophetic dream from three years prior, which he believed was a vision of his own death, turns out to instead be a vision of his rescue from space. Bubblegum had not been the only one planning to travel into space to see the Comet; Banana Man has also completed his own rocket-ship. 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. [The Comet]

Since the Purple Catalyst Comet did not actually collide with Earth, it is unclear whether or not it delivered an Agent of Change. Martin's exact fate is also unclear. 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. [The Comet, Bonnie and Neddy]

The Former Princess Bubblegum

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 brother Neddy underneath the tree at the centre of the Candy Kingdom 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. [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. [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. [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. [Marceline the Vampire Queen]

---

1000 AMB / 3010 CE

Return of the Vampire Court

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. [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 Hierophant, 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. [Everything Stays, 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. [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. [Vamps About, The Empress Eyes]

Next on their list is The Moon, but before that they are intercepted by The Hierophant. 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 Hierophant 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. [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. [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. [Take Her Back]

But the Vampire King does not want things to repeat. [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 and blows Peppermint Butler to pieces, but the others all survive. [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. [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. [The Dark Cloud]

The Vampire King becomes a voice in Marceline's head, but apart from that the Vampire Court is gone for good. The power of the Dark Cloud remains within Marceline, ready to be harnessed if it is ever needed in the future. Toronto escapes the revolution against the King of Ooo with enough stolen loot to stay afloat. Princess Bubblegum puts Peppermint Butler back together again. [The Dark Cloud, Come Along With Me]

BMO Grows Up

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. [Guardians of Sunshine]

BMO has a highly developed network of imaginary relationships, mostly with animals and inanimate objects around the Tree Fort. Even since before he met Finn and Jake, he has personified 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. [BMO Noire, BMO, BMO Lost, Football]

Although they are arguably neglectful of BMO for some time, Finn and Jake eventually grow to love BMO almost like he was their own son. [Shh!, Imaginary Resources]

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. BMO chooses to keep living with Finn and Jake rather than returning to his own people. [Be More]

As mentioned previously, one of Moe's earliest creations was AMO. 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. [The More You Moe The Moe You Know]

Sometimes, BMO likes to relive his days as sheriff of the Drift by roleplaying as a cowboy. BMO 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 her locked up in the Candy Kingdom. However, at some point, she escapes or is released. [BMO, Angel Face, Gumbaldia]

In addition to this, BMO finds an unexpected friend in the Ice King. They are a good fit. [President Porpoise is Missing!, 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. [Come Along With Me]

Peace in Farmworld

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 main timeline 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. [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 main timeline. [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 keeps the version of the Enchiridion from Farmworld since their native copy was destroyed, thinking it might come in useful. [Crossover, Winter Light]

Exceptional Beasts

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. One day she encounters Finn and recognises that his flute-playing is guided by a magical spirit; the spirit of the Grass Sword, which is currently contained within the thorn in Finn's hand. She believes his music might help her contact the Spirit of the Forest. [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 starts helping Huntress Wizard 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, and they share a kiss. But Huntress Wizard doesn't believe they should be together, claiming that love is restrictive and prevents people from fulfilling their potential. [Flute Spell]

In the process of finding the Spirit of the Forest, Finn drinks from an enchanted spring which grants him immunity to electrocution. [Flute Spell]

Despite claiming that their relationship wouldn't work out, Huntress Wizard appears to retain an interest in Finn. [Wheels]

Friendship in the Fire Kingdom

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. [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. [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. [Bun Bun]

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, who has become an independent con artist following the revolution against the King of Ooo, attempts to scam the Fire Kingdom from her by having her lose a rap battle against teen prodigy Son of Rap Bear. Flame Princess is able to channel her feelings about her father into a verse which wins the battle. [Son of Rap Bear]

Fern the Human

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. [I Am a Sword, Normal Man]

Within the gem of the Finn Sword, the alternate version of Finn is joined by the spirit of the Grass Sword's curse, which manifests as a Grass Demon who takes over the inside of the gem. [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. [Don't Look, The Hall of Egress, 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 the 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 surgeries on 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. Several of the hybrids from the lab escape into the Land of Ooo. [Preboot, Dentist, Come Along With Me]

non-canon information
According to one account, Doctor Gross also survives the explosion. [Ted Anderson]

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 doppelgänger of Finn. [Reboot]

Understandably, Grass Finn 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 Grass Demon. 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. 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. [Two Swords, Do No Harm]

It is around this time that Finn begins using the Small Sword, which was presumably given to him by Rattleballs. [Rattleballs, Do No Harm]

999 AMB to 1000 AMB / 3009 CE to 3010 CE

The Veritas Brigade

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 Peacemaster, 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 Peacemaster eventually confront one another in the Wizard Battle Arena, and Peppermint Butler wins him over by threatening to turn his children into evil monsters. [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. [We Fixed a Truck, High Strangeness, 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. [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. [High Strangeness, Escape from the Citadel, Ring of Fire, Always BMO Closing, Come Along With Me]

non-canon information
According to one account, Tree Trunks writes an entire line of short novels set in alternate versions of the Land of Ooo, under the secret pen name of "T. T. MacDangereuse". Most of them feature alternate depictions of the real people of Ooo, and one of them uses the gender-swapped characters from Ice King's fan-fictions. [Queen of Rogues, The Untamed Scoundrel, The Lonesome Outlaw, The Virtue of Ardor]

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. [Graybles 1000+]

James Baxter

James Baxter the Horse continues to travel the Land of Ooo with his beach ball, spreading joy and happiness everywhere he goes. Finn and Jake decide they want to try to do the same, and develop their own technique for cheering people up. [James Baxter the Horse]

Later on, James Baxter's beach ball breaks and Finn and Jake take it upon themselves to help him. The horse falls into a depression until Finn helps him realise that in order to cheer other people up, he also has to be able to cheer himself up. He forgoes a replacement beach ball and heads out into the world to try something new. [Horse and Ball]

1000 AMB / 3010 CE

Return to the Islands

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. [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 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. [The Invitation, Daddy-Daughter Card Wars]

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. [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. [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. [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 human players to emerge into the real world, where they struggle to move due to their decrepit and atrophied bodies. Finn and Jake decide 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. [Imaginary Resources]

They travel by tube to the ruins of Hub Island, which was abandoned following Doctor Gross' epidemic. On its shores they reunite with 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. [Hide and Seek, 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. [Helpers, 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 forcibly upload the entire population into the virtual world. But she changes her mind after realising that if the outside world turned Finn into a good person, then it can't all be bad. [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. [The Light Cloud, Islands graphic novel]

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. [The Light Cloud, Everything Stays, Come Along With Me]

And slowly, over the next few years, humanity will begin to spread itself back out to inhabit the world it left behind. [Come Along With Me]

1000 AMB / 3010 CE

Elementals Reunited

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 thinks 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. [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. [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. [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. [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. [Skyhooks, Winter Light, Slime Central, Happy Warrior]

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 spell protects him from the changes. [Skyhooks, Bespoken For, Skyhooks II, 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". [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 landfall 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. 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. [Orb, 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... [Winter Light, 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. [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. [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. [Hero Heart, 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. Carol, having already transitioned through the other two phases of water, becomes a water nymph. And unbeknownst to anyone else, Punchy, Crunchy, and Manfried are released from their imprisonment, becoming Gumbald, Lolly, and Chicle once again. [Skyhooks II, Come Along With Me, Seventeen]

1000 AMB / 3010 CE

Fern's Corruption

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. Despite previously resolving to try to establish himself as a completely new person, Fern can't help but draw comparisons between himself and Finn. [Whispers]

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. [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. [Whispers]

Being knocked out by Sweet P and missing the fight against The Lich further compounds Fern's insecurities. Additionally, Finn fails to recognise that Fern doesn't really want to learn to be his own person. He wants to be Finn, because that's who he's always been. Seeing this as an impasse, and egged on by the Grass Demon that clings to his mind, Fern begins to consider drastic action. [Whispers]

Soon, Fern discovers that his shape-shifting powers allow him to perfectly imitate Finn's appearance. Emboldened by this new power, and angered by Finn's apathy towards his situation, Fern comes up with a plan to replace his counterpart. Under the guise of an innocent dungeon crawl, he deceives Finn into accompanying him to a ziggurat dungeon, where he locks him inside a stone chamber and abandons him. Fern, disguised as Finn, begins heading back to the Tree Fort to inform Jake of "Fern's" unfortunate demise. But the real 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 before he reaches the Tree Fort and they battle it out. While pinned down, Finn mistakenly orders his arm to increase its power, and Fern is disintegrated before his eyes. Finn returns to the Tree Fort alone, distraught by the belief that he has killed Fern. [Three Buckets]

Shape-Shifters

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. [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. [Abstract, 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 Clockbear, 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 Clockbear 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. [The First Investigation, 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. [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. [Temple of Mars]

non-canon information
Finn also gets briefly trapped far from Earth after being abducted to the Vanishing Point for breaking his oath to Jake. 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. Chronologius Rex takes pity on Finn and allows him to escape with Jake, and the two embark on their journey through time until eventually making their way back to the present day. [Beginning of the End #1 to #3 and bonus chapter]

Gumbald and the Green Knight

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. [The Pajama War, The Dark Cloud]

Following the reversal of Patience St Pim's elemental spell by Lumpy Space Princess' anti-elemental influence, the effects of the dumdum 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 where Fern tried to trap Finn, 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. [Always BMO Closing, 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. [The Wild Hunt]

Despite previously claiming that they cannot be in a relationship, Huntress shares a kiss with Finn. It's possible she overcame her flawed perception of love at some point and no longer believes it is a weakness. 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. [The Wild Hunt]

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 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. [Always BMO Closing, 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 threatens to decapitate Finn, 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. [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. [Marcy & Hunson]

non-canon information
According to one account, 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]

Soon, Gumbald, Lolly, and Chicle have established their own kingdom named Gumbaldia. The conflict between the Candy Kingdom and the Kingdom of 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 builds 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, Peacemaster, 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. [Gumbaldia]

1001 AMB / 3011 CE

The Great Gum War

Finn and Jake secretly leave on a last ditch diplomatic mission to the Kingdom of 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 dumdum 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 dumdum 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. [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 the Kingdom of 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. [Come Along With Me]

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. [Come Along With Me]

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. [Come Along With Me]

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. [Come Along With Me]

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 Fern 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 Grass Demon; 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. [Come Along With Me]

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. [Come Along With Me]

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 dumdum 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 the Kingdom of 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. [Come Along With Me]

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. 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. [Come Along With Me]

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. [Normal Man, Come Along With Me]

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 gnashes his teeth together and traps them inside. Finn's bionic arm is severed from his body and falls to the battlefield below. [Come Along With Me]

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 Betty's arrival. But with only minutes left until they are consumed by GOLB, her joy is short-lived. [Come Along With Me]

Ricardio, who was in league with Gumbaldia, likely dies following Simon's return, since he is known to have died at around the same time as the Grass Demon. [Together Again]

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. To Jake's horror, the monsters completely and irreparably obliterate the Tree Fort. [Come Along With Me]

non-canon information
According to one account, the monsters also destroy a significant portion of the Candy Kingdom capital. [Season 11 #1]

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. [Come Along With Me]

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. [Come Along With Me]

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 such a powerful entity. 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. [Come Along With Me]

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". [Come Along With Me]

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 Grass Demon holding him together, Fern has used up the last of his energy fighting alongside his friends. [Come Along With Me]

He disintegrates at Finn's side, 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. [Come Along With Me]

1001 AMB / 3011 CE

After the War

Although the war is finished, the adventures of Ooo's inhabitants are far from over.

Aunt Lolly becomes the ruler of the Kingdom of Gumbaldia, which peacefully coexists alongside the Candy Kingdom. Punchy and Crunchy, the dumdum versions of Gumbald and Chicle, happily reintegrate into Candy Kingdom society, although their true selves are presumably still trapped within their minds. [Come Along With Me]

Despite Princess Bubblegum's previous offer to let Marceline come and stay in the Candy Kingdom, it is instead Bubblegum who moves into Marceline's house. The two of them live together happily. Princess Bubblegum seems to continue ruling the Candy Kingdom, since she keeps her crown, but the fact she's happy to live elsewhere suggests she's stopped being so attached. This was one of the main causes of her last breakup with Marceline. [The Dark Cloud, Obsidian]

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, covering up the mural depicting the Legend of Matthew. [Come Along With Me, Princess Day, The Mountain]

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. The King of Ooo is seen at their wedding, having reformed following his dethronement at the hands of Crunchy. [Come Along With Me, The Dark Cloud]

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. He struggles to recover from his time as the Ice King, sometimes wearing his old blue muumuu and hanging out near open freezers. He pursues music as an outlet, sometimes performing at Dirt Beer Guy's tavern. [You Forgot Your Floaties, Come Along With Me, Obsidian]

Eventually, many ships full of humans make the crossing from Founders' Island to the Land of Ooo, ready to re-inhabit their abandoned Earth. [Come Along With Me, Simon Petrikov]

10?? AMB / 30?? CE

Return to the Glass Kingdom

A glass person named Glassboy is ridiculed by the other subjects of the Glass Kingdom for the crack on his head. After the annual retelling of the story of Saint Marceline, Glassboy steals the key to the Furnace, where the dragon Molto Larvo has lain dormant ever since being cast away by Marceline. Glassboy believes that Marceline slew the dragon, and that the glass people have no reason to be afraid of the Furnace anymore, so he travels into its depths in an attempt to repair the crack on his head. Unfortunately, his assumption was untrue, and his presence awakens the dragon. He is locked up by the kingdom's advisors, but See-Thru Princess, the ruler of the kingdom, sets him free. To make up for his mistake, Glassboy travels to the Candy Kingdom to seek out Marceline so she can once again banish the beast. [Obsidian]

While searching for the Candy Kingdom, Glassboy bumps into Choose Goose, who is on his way to deliver illegal moisturiser to Bufo in Wizard City. [Obsidian, Wizard City]

Glassboy reaches the kingdom, and with help from Simon, he arrives at the home of Marceline and Bubblegum and persuades them both to return to the Glass Kingdom with him. Princess Bubblegum, secretly suspecting that Marceline's song will not be enough to imprison Molto Larvo a second time, organises for the Morrow to follow their motorcycle at a distance, carrying a force field and other scientific equipment in case Marceline's plan fails. Indeed, when Marceline sings the breakup song a second time it has no effect other than resurfacing Princess Bubblegum's bad memories. Marceline feels insulted when Princess Bubblegum reveals she was expecting things to go wrong. Glassboy tries to vouch for Marceline, but See-Thru Princess sides with Bubblegum. Marceline leaves to seek out tragic places from her past so she can write a new, even angrier song for defeating the dragon, while Princess Bubblegum stays in the Glass Kingdom and tries to find a technical solution. [Obsidian]

Marceline revisits the bunker where her mother sent her following the war, and finally discovers the message that was left for her all those years ago. [Obsidian]

Glassboy has stowed away in the bag on Marceline's motorcycle, and ends up performing his own angsty punk song about his annoyance at See-Thru Princess. Realising how petty her own angsty songs must sound, and realising that her anger at her mother has been misplaced for all these years, Marceline decides to forgive Bubblegum and return to the Glass Kingdom to help her. [Obsidian]

On their way back, the minions of Molto Larvo irreparably destroy Marceline's bass guitar, the Abadeer Axe. Bubblegum, meanwhile, is not having much success either. She plans to encase Molto Larvo in frozen root beer, but the plan only manages to make the dragon angrier. Marceline returns to find it rampaging through the kingdom. Glassboy lures the dragon into the Furnace, pursued by Marceline and Bubblegum. See-Thru Princess' advisors decide that the best course of action is to crank Bubblegum's force field up to maximum and trap all four of them for good. Believing this might be the end, Marceline decides to play Bubblegum one last song she's been working on. [Obsidian]

Marceline and Princess Bubblegum share a kiss. Just like Marceline's breakup song drove Molto Larvo to anger and fear, her love song provokes an opposite reaction and drives the dragon to remember its own tragic past. The dragon undergoes a metamorphosis, and from its body is born a harmless and carefree new creature. See-Thru Princess overrules her advisors and destroys the force field to release Glassboy and the others. In the process, her body is cracked, but she refuses to step down and let her advisors take over. Instead, it is revealed that the advisors themselves, along with many other glass people, have actually been hiding their own cracks the whole time. [Obsidian]

Simon, Finn, Bronwyn, and a squadron of banana guards arrive a little too late to be of any help, but stick around for the after-party. Jake has passed on by this time, and Finn has a tattoo of him on his chest in memory. Marceline and Bubblegum share a dance, and the Glass Kingdom is safe once more. [Obsidian, Simon Petrikov]

10?? AMB / 30?? CE

The Cult of Coconteppi

By this time, Bufo has supposedly given up dark magic and been released by the police after snitching on his accomplices, Laser Wizard and Forest Wizard. He becomes a transmutation teacher at Wiz Arts, while also secretly being a member of the Cult of Coconteppi alongside fellow teachers Berdzerd (astral projection), Dimension Wizard (divination), Brain Wizard (transfiguration, and also headteacher), and Doctor Caledonius (magical history). Also in the cult is Potable Wizard, owner of the popular student café "The Brew". Together, they have been continuing the cult's goal of locating the tomb of Coconteppi, unaware that it is directly beneath the very school in which they teach. [Wizard City]

On the same night that Glassboy reaches the Candy Kingdom, Choose Goose reaches Wizard City and delivers a supply of illegal moisturiser to Bufo. Choose Goose drinks from a water fountain at Wiz Arts which has become contaminated by the ichor produced by the rotting heart of Coconteppi and appears to explode and die as a result. Bufo, recognising what this means, informs the other cultists that he has finally discovered the location of the tomb. They begin to search for a vessel powerful enough to drink Coconteppi's ichor and bring about the Second Age of Terror. [Obsidian, Wizard City]

Shortly after this, a new term begins at Wiz Arts, and one of the students in attendance is none other than Peppermint Butler. Since being babified by the effects of Gumbald's dumdum juice, Peps has regrown to school age and now plans to relearn his magic so that he can once again become a powerful dark wizard. All of this is done under the influence of the curse which he placed on himself, which manifests as a ghostly projection of his old self that yells at him when he doesn't get the best possible results. [Wizard City, Gumbaldia]

Peps is placed into the low-rank skink class alongside aspiring stage magician Cadebra, who is the niece of Abracadaniel. Abracadaniel himself is a janitor at Wiz Arts. Several other members of the Order of Giuseppe have become teachers at the school, including Life-Giving Magus (enchantment), Little Dude (assistant to Dimension Wizard's divination class), Ron James (potions), Leaf Man (herbalism), and Beau (illusion). Thankfully, none of the Order appear to be involved with the Cult. Peps struggles to keep up with Spader, a student in the prestigious salamander class, as well as Spader's cousin Larry and his friend Blaine. Larry gets turned into a rock during Bufo's class for making fun of Bufo. Nobody realises that Peps and the infamous dark magician Peppermint Butler are one and the same person. [Wizard City]

After the first day of school, Blaine overhears Peps in the bathroom at The Brew, conversing with the curse of his former self. When Spader goes missing the next day, Blaine falsely suspects that Peps is responsible. After searching Peps' belongings they discover a photo album proving that he was once the notorious Peppermint Butler. They inform their father, a member of the Wizard City police, and the two of them set out to arrest Peps. The innocent Peps plans to plant fake evidence in Bufo's office to absolve himself of Spader's disappearance, but instead he finds Bufo dead. At this moment, Blaine bursts in with his father, and they arrest Peps on suspicion of the murder of both Spader and Bufo. Only Cadebra remains faithful that Peps didn't commit the murders. [Wizard City]

Spader's actual murderers were, of course, the Cult of Coconteppi, who thought that their star student might be powerful enough to take the ichor and allow Coconteppi to rise once more. But Spader was not powerful enough, and the ichor killed him. And Bufo wasn't murdered at all. He tried to take the ichor for himself, only to discover that he was also too weak. His tadpoles survive his death. [Wizard City]

Peps escapes his capture. Cadebra and Doctor Caledonius, who pretends to be sympathetic to Peps' situation, team up to try to find him before the police do. But Doctor Caledonius' actual motive was to get Peps to the tomb of Coconteppi so that he could be fed the ichor, since she now knows that he is the infamous dark wizard Peppermint Butler. To Cadebra's horror, Peps gives in to the persuasions of his cursed former self, and accepts the ichor. Rather than being killed like the previous subjects, Peps begins to grow and transform as Coconteppi emerges from his millions of years of slumber having finally found a worthy host. The monstrous Peps slays the entire cult. Doctor Caledonius perishes with laughter and delight, satisfied in the knowledge that she has finally brought about the Second Age of Terror. But she is wrong. [Wizard City]

Cadebra, trusting that Peps still resides somewhere within Coconteppi, distracts him with stage magic and succeeds in getting him to regurgitate the ichor. Peps returns to his regular self. The curse of Peppermint Butler is furious, but Peps is finally tired of being told his destiny, so he rips out the curse and frees himself. The Second Age of Terror has been averted. For now. [Wizard City]

Following the death of Brain Wizard and half the other Wiz Arts teachers, the conjuration teacher Weapon Head becomes the new headteacher. For defeating Coconteppi, Peps' charges for the past crimes of Peppermint Butler are dropped. He turns down a promotion to the rank of salamander so that he can continue to be in skink class with Cadebra. The two of them manage to transmute Larry back into a person, and are forced to break the news that his cousin has been killed. [Wizard City]

Meanwhile, it turns out that Choose Goose has somehow survived the deadly effects of the ichor, and he revels in its dark power. He retrieves Bufo's tadpoles from the tomb of Coconteppi, and puts his evil plans in motion... [Wizard City]

1013 AMB / 3024 CE

Simon's Crisis

It has been twelve years since the Great Gum War and Betty's amalgamation with GOLB. The human settlers of Ooo have built a futuristic city in the sky, and Simon lives among them. But although they are humans, these are not his people. Simon is an outsider from another age. He makes money by acting as a literal exhibit; a living demonstration of what humans were like a thousand years ago. He struggles to find any meaning in his life. He has managed to give up his habit of wearing Ice King's old clothes as a coping mechanism, but the trauma of his time as a mad wizard still haunts him, as does the unexpected success of his Fionna and Cake fan-fictions, which have become a sleeper hit following his restoration. Simon resents his past and insists that it was the Ice King who wrote those stories, not him. He makes a little girl named Astrid cry by throwing her copy of his stories in the trash, which makes him feel awful. [Simon Petrikov]

Unbeknownst to Simon, the real Fionna and Cake universe in his mind was fundamentally changed when he regained his sanity. No longer is it a world of magic and wonder. In a city on ordinary twenty-first century Earth, Fionna Campbell lives an ordinary life with her ordinary cat. Like so many ordinary people, she is going through tough times. After a recent breakup with her boyfriend "DJ Flame", and being fired from the most recent of the five jobs she has held this year, she is struggling to pay rent. Aside from her cat she is good friends with Marshall Lee, a busker whose mother is Fionna's landlady, and Gary Prince, an employee at a coffee shop bakery called Butler's Buttery Buns. [Fionna Campbell]

Meanwhile, Finn continues his life as an adventurer and a hero of Ooo. He mourns the loss of Jake, but he takes on some of Jake's descendents as apprentices, including Bronwyn and T.V. He remains on good terms with Huntress Wizard but the state of their relationship is unclear. Finn tries to cheer Simon up by taking him on a daring adventure into the Heart of the Forest, but it only makes Simon feel more out of place in the Land of Ooo and he goes home injured and upset. [Obsidian, Simon Petrikov]

Driven over the edge, and egged on by an evil Choose Goose whom Simon is using as a magic battery, Simon opens up his secret shrine and attempts to summon GOLB so that he can see Betty again. The ritual fails, but a different connection is made. [Simon Petrikov]

Within the universe in Simon's mind, Cake begins acting up, and without any money for the vet, Marshall Lee recommends that Fionna takes her to his contact; a dodgy individual named Ellis P. who claims to be able to commune with animals. Ellis feeds Cake catnip, and while tripping out she jumps into an ice cream vendor's stall and mysteriously disappears. A bewildered Cake emerges from the back of an equally bewildered Simon's head, and this ordinary cat suddenly finds herself in the extraordinary Land of Ooo. It doesn't take long for Fionna to follow her, through a freezer in Butler's Buttery Buns, and they both quickly fall in love with the Land of Ooo. Cake gains a voice after Simon provides her with a universal translator. [Fionna Campbell, Simon Petrikov, Cake the Cat]

Unfortunately for Prismo, this crossover attracts the attention of Scarab, his auditor, which threatens the secrecy of the unauthorised Fionna and Cake universe. Prismo teleports Fionna, Cake, and Simon to the Time Room. He restores Cake's voice and stretchy powers, and reprimands Simon for the attempted GOLB ritual. But before he can send everyone back to their appropriate universes, Scarab arrives demanding answers. In a rush, the trio escapes to Farmworld with Prismo's dimension-hopping remote control, leaving Prismo to fend for himself. And Simon comes to a realisation. The only way to restore Fionna and Cake's universe to its normal state would be for him to once again become Ice King, which would mean sacrificing his sanity and throwing away all Betty's efforts to bring him back. But this idea doesn't seem to bother him as much as it should. All they need is a crown. [Prismo the Wishmaster]

With this new plan, the trio begin exploring Farmworld for crowns. They are picked up by a boy who turns out to be the offspring of the Farmworld version of Finn, who has settled into a family life since being cured of the crown's madness. The boy is named Jay, and he has a sister named Bonnie as well as three other siblings. Jay and Bonnie were also the names of Finn's children in Pillow World. Farmworld Finn is a widower, and the identity of his children's mother is not known. [Destiny, Crossover, Puhoy]

Against his father's wishes, Jay takes Simon, Fionna, and Cake to the crater where the Mushroom Bomb vaporised this universe's version of Evergreen's crown. Jay reveals that he is in a starcrossed relationship with Little Destiny, the heir to the frightful Destiny Gang. When they first fell in love, he gifted her a jewel he found in the crater; a jewel from the crown, which unbeknownst to either of them is making her sick. Finn arrives to help fend off an altercation with Big Destiny and the rest of the gang, but it turns out they are also being pursued by a much more dangerous enemy: Scarab, who has found a way to jump between dimensions without the use of Prismo's remote. Cake retrieves the jewel from Little Destiny and, even amid all the fighting, Simon is able to use it to program the remote to locate more crowns throughout the Multiverse. Scarab incapacitates Finn and grabs onto our trio just as they jump away to the next universe. [Destiny]

Their next destination is a winter wonderland ruled over by the benevolent Winter King, who freezes Scarab as soon as the four of them fall through into his kingdom. The Winter King claims that through sheer force of will he was able to overcome the madness of Evergreen's crown, which our Simon finds a little depressing. Of course, this is too good to be true. It doesn't take long for Fionna and Cake to learn about the Candy Queen, who kidnaps the Winter King. Following a rescue mission, Fionna's presence somehow removes the magic from the crown, causing the Winter King's age to rapidly catch up with him, and he dissolves into ash. With the curse he placed on the Candy Queen lifted, she reverts back to her true form; Princess Bubblegum. A long process of reconstruction lies ahead of her. Our trio, discouraged but not lost, part ways with her and move on to the next dimension, shaking off Scarab's pursuit for now. [The Winter King]

Their next stop, a world where everyone is a baby, turns out to be a dead end too. They accidentally abduct Baby Finn and bring him with them on their adventures. [The Winter King, The Star]

The next dimension visited by the trio is the world where Simon was killed by vampires, and where Marceline was instead raised by the Vampire King under the moniker of The Star. By now she is the only surviving member of the Vampire Court aside from the King himself, plus their myriad minions. After over a thousand years, human blood is finally beginning to run a little dry, and the reign of the vampires is not set to last much longer. The Star's arch rival is an alternate version of Princess Bubblegum; a rugged survivalist with a self-repairing battle-tank, which is itself this universe's version of Peppermint Butler. Accompanying her are a childless Martin Mertens and a human version of Huntress Wizard. Together with Simon, Fionna, Cake, and Baby Finn, Bonnie leads an attack on the vampire hive. This is a mutually beneficial arrangement, as the Vampire King possesses this world's crown and is using it to keep the sky permanently clouded so that the deadly sun cannot harm his kin. [The Star]

The attack is unsuccessful. The Star kills Martin, the Vampire King kills Huntress, and the tank is incapacitated. Bonnie and The Star, their fates inseparably entwined even in a world where they are sworn enemies, fall from the top of the hive and plummet to their death in each other's hateful embrace. Simon, Fionna, and Cake use the last of the remote's remaining jumps to escape this dimension. Baby Finn is left alone in the care of the battle-tank. [The Star]

Within Simon's mind, Marshall Lee and Gary Prince meet for the first time. Gary helps convince Marshall to escape the clutches of his mother, the ultra-wealthy businesswoman Hana Abadeer, and the two of them share a kiss. [The Winter King, The Star]

Our trio's next destination is the world that was created when the Lich wished for the extinction of all life. It is a silent desert full of nothing but bones, lignin, and the inorganic paraphernalia left behind by the living. Prismo's remote is broken, leaving them stranded in this terrible realm. Somehow this universe's BMO survived the wish, perhaps due to being a robot or perhaps by other means. The Lich also inhabits this world, but with all his goals achieved and nothing left to do he is depressed and inert. BMO dies in an unsuccessful attempt to repair Prismo's remote. Fionna discovers this universe's version of the crown in the place which was once the Ice Kingdom. She is reluctant to give it to Simon after learning more about what the Ice King was really like, but eventually concedes that it is the only remaining course of action. [Jerry]

Meanwhile, Scarab's supervisor Orbo intervenes in the pursuit of Fionna and Cake. Scarab manages to strike a deal with their mysterious Boss, allowing the chase to continue. [Jerry]

Using the Lich as a magical power source, Simon performs his GOLB ritual once again and Fionna and Cake enter back into his mind. Scarab arrives to kill him just as he is about to place the crown back onto his head, but both of them are interrupted by GOLBetty, who drags them through into her domain. [Jerry]

The Lich pleads with GOLBetty to tell him why wiping out all the life in his universe has brought him no satisfaction. In response, GOLBetty simply annihilates him, turning him into one of the blocky structures that orbit her body. Scarab tries to finish his assassination of Simon, but GOLBetty disintegrates him into a bunch of small beetles. The beetles crawl into Simon's head and enter Fionna's world. GOLBetty refuses to allow Simon to put on the crown, temporarily transporting his mind a thousand years into the future so that he can learn some lessons about himself. [Casper & Nova]

Back in his own body in GOLBetty's realm, Simon's revelation causes him to cough up the universe that was inside his head. It takes the form of a dandelion; an unmade wish. Since Fionna's world was created by Prismo without anyone making a wish, the wish that would have created it remains unused. Simon passes the dandelion to Fionna through the still-open portal in the back of his own head. [Cheers]

Meanwhile, Fionna and Cake reunite in their own universe with Marshall Lee, Gary, Ellis P., and local park-keeper Hunter. They fail to keep Scarab's many parts from reuniting, and he begins to tear apart their world. But when Fionna receives the dandelion from Simon, she is able to make a wish. She wishes for her world to be real. She sees that her world doesn't need to be magical for it to be her home, and she doesn't want to erase all the stories that have taken place there, no matter how mundane they might be. The world becomes a legal part of the Multiverse. [Cheers]

Even the canonisation of the universe and a call from the Boss don't convince Scarab to cease his rampage. Prismo summons a selection of friends from Fionna and Cake's adventures to help our heroes defeat him; Jay Mertens, Little Destiny, a squirrel who Cake met in Ooo, Baby Finn, and Bonnie's battletank (but not Bonnie herself). Together they succeed in stealing Scarab's staff and imprisoning him in an egg, to be dealt with by the other gods. [Cheers]

Fionna and Cake enjoy their universe's new official status and together with their community begin rebuilding the damage caused by the battle. Although the world remains un-magical, Cake retains her stretchy powers and the other interdimensional interlopers decide to stay, bringing a little of the magic that Fionna was so desperately craving. Prismo gets Scarab off the hook and takes him on as an intern in his Time Room, hoping to reconcile. Simon is returned to Ooo by GOLBetty. He finally begins talking to his friends and to a Minerva-therapist about his problems. His stories inspire Astrid to create a pair of characters named Casper and Nova, based on Simon and Betty, who go on a series of quests in space to find magical artifacts. [Cheers]

And with their adventure at an end, life is looking just a little more hopeful for both Simon and Fionna. Sometimes that's all you need. [Cheers]

A New Candy Kingdom

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. [High Strangeness]

10?? AMB / 30?? CE

The End of Finn and Jake

Like all mortals, Finn and Jake must eventually cash in their chips. As already mentioned, Jake was the first to go. His death is foreseen by his daughter Charlie, whose vision predicts that he will die when Charlie is in her twenties, although it's up to speculation how long that actually is when taking into account the very unconventional ageing process of the pups. In the vision, Jake chokes on a sandwich, but this could be metaphorical rather than his literal cause of death. Charlie also foresees the birth of her son Gibbon, who is Jake's grandson. [Together Again, Daddy-Daughter Card Wars]

Over time, Princess Bubblegum seems to give up some of her control over the Candy Kingdom, probably so that she can spend more time living her life with Marceline. She continues to undertake diplomatic missions and other functions, but Peppermint Butler takes over much of the day to day administration of the kingdom once he has completed his education at Wiz Arts. He eventually even gains the crown and the title of princess. He overhauls the Candy Kingdom, and openly uses his magical abilities in its development and upkeep. [Obsidian, Together Again, Wizard City]

Finn leads a long and fulfilling life, though as is the case for everyone, he begins to lose more people around him as he gets older. Jermaine leaves Finn as the last of Joshua and Margaret's living children, and many of Finn's other friends also pass on, including Mr. Fox, Booshy, and Tree Trunks and her various consorts. Finally, after many years of adventure, it is time for an elderly Finn to join his brothers in the afterlife. [Together Again]

The Land of the Dead has undergone a change in leadership since Finn's last visit. Life and Death had a son, but their son has been befriended by a mysterious and malevolent entity. Death's attempts to wean his son away from his new friend prove fruitless, eventually culminating in his son slaying his own father, taking upon himself the title of New Death and inheriting all the responsibilities that come with it. But New Death does not care for these responsibilities, and the influence of his new friend continues to grow... [Together Again]

When Finn arrives in the Land of the Dead, Mr. Fox is assigned to be his guide to the afterlife. Finn demands an audience with New Death so that he can be reunited with Jake. He is intercepted by none other than his old frenemy Tiffany, who has become an undertaker serving New Death. Tiffany tells Finn that Jake has made it to the Fiftieth Deadworld and takes him inside the castle. There Finn meets New Death, who realises that Finn could be his way into the Fiftieth Deadworld, which even he has not been able to access before now. Finn steals Tiffany's harmonica, a device which allows the user to travel between deadworlds, and begins searching for the Fiftieth. [Together Again]

Finn travels through many deadworlds and meets many of his deceased friends and family. He finds Tree Trunks and her various lovers in the Thirtieth Deadworld. In the First Deadworld, which is the worst of them all, he finds Choose Goose, who was presumably placed there for crimes involving the ichor of Coconteppi. And then, in the Forty-Fifth Deadworld, he finds his family; Joshua, Margaret, and Jermaine. Finn is reunited with his parents for the first time since they died when he was a young child, but Jake is still nowhere to be found. [Together Again, Wizard City]

Meanwhile, New Death, under the influence of his mysterious friend, commences the demolition of the deadworlds. The Forty-Fifth is obliterated by the undertakers but Finn is spared. Believing that he has just lost his parents for a second time, Finn almost loses hope, but at that moment his emotional outburst is detected by none other than Jake himself. Descending from the Fiftieth Deadworld, Jake is reunited with Finn once more, and despite having achieved separation from all desire, Jake quickly remembers that Finn is his brother and returns to his old self. [Together Again]

By this time, New Death has arrived to exploit the entrance to the Fiftieth from which Jake descended. New Death destroys the Fiftieth Deadworld, and before long almost all the souls in the afterlife have fallen down to the First, which is one of the few that still remains. Finn and Jake decide to visit the world of the living as ghosts to ask for advice from Princess Peppermint Butler. He directs them to the domain of the goddess Life, the mother of New Death and the creator of all reincarnated beings. She is initially apathetic over her son's actions, saying that the deadworlds are his jurisdiction and she is happy as long as she has her purpose. But as they are talking, New Death shuts down her kiln, preventing her from creating any more lives. In a rage, she sculpts the Kiss of Life, a staff capable of killing Death, and gives it to Finn and Jake so that they can slay her son and allow the cycle of reincarnation to continue. [Together Again]

Back in the Forty-Fifth Deadworld, Tiffany has saved Joshua, Margaret, and Jermaine from falling into the First Deadworld out of respect for Finn and Jake. He comes to the realisation that New Death's actions are wrong, and teams up with Finn and Jake when they return from Life's domain. Together, they travel back to the Land of the Dead and infiltrate the castle, with Finn and Jake using their past lives as Shoko and her tiger as a disguise. Tiffany and the dogs take care of the undertakers while Finn and Jake go to the castle's observatory, where New Death is overseeing the demolition of the deadworlds while Mr. Fox butlers for him. Finn and Jake engage New Death in combat, but while the Kiss of Life is able to hit New Death, it doesn't appear to be killing him. During the fight, New Death's mysterious friend takes full control of his body and reveals his true identity; it is The Lich, persisting even in death. By demolishing the deadworlds and cutting off reincarnation, all The Lich would have to do is wait for the rest of the beings in the Multiverse to die, and his quest to end all life would be complete. [Together Again]

Finn and Jake know that whoever strikes down The Lich with the Kiss of Life will become the next Death; a burden which neither of them want the other to bear. So while The Lich is temporarily trapped with the help of a talisman from Margaret, they fight over possession of the Kiss of Life. During the fight they take many of their past forms in an effort to gain the upper hand, but neither takes the advantage. Instead it is Mr. Fox who ends up holding the Kiss of Life when The Lich burns away the talisman, and in a twist of events, it is he who strikes down New Death and The Lich. The reason Finn and Jake didn't manage to do so before was that they were holding the staff by the wrong end. New Death is obliterated, and once again all that is left of The Lich is his hand, which Jake casts out into the wasteland, perhaps to someday again return... [Together Again]

Mr. Fox becomes the next Death. He reconstitutes the demolished deadworlds and returns all the souls to their proper places, and restarts Life's kiln so that the cycle of reincarnation can continue. Joshua and Margaret adopt Tiffany, becoming the family he never had. Finn chooses to be reincarnated again, and Jake initially chooses to return to the Fiftieth Deadworld. After an emotional farewell they go their separate ways. But at the last minute, Jake changes his mind to join Finn, and the two of them prepare for their next life, together. [Together Again]

A Thousand Years Later

Time brings many changes to the Land of Ooo.

BMO becomes something of a legendary figure, taking the title "King of Ooo" (not to be confused with the other King of Ooo) and moving 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. [Come Along With Me]

Some of the other characters from the time of the series are known to survive until this time. Sweet P (formerly The Lich) ironically 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. [Come Along With Me]

Other characters do not get the opportunity to live forever, but still live on in legend and memory. The Jiggler's casket and Mr. Fox's skull are seen in BMO's collection. Giant statue monuments to Finn and BMO are seen, as well as a monument to either Jake or Jermaine. [Come Along With Me]

A travelling salesbird named Pawn Swan roams the land selling his wares, much like Choose Goose did a thousand years before him. [Cheers]

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 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, Evicted!, Come Along With Me]

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. [Lemonhope Part Two, Graybles 1000+]

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. [Lemonhope Part Two]

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 and reinvent advanced space travel, connecting Earth with other space-capable civilisations including the grey aliens. The pups are ruled by Gibbon, the son of Charlie and one of Jake's grandchildren. Gibbon has obtained one of the jewels from the Ice Thing and used it to attain immortality and his own ice powers. He rules with an iron fist. [Come Along With Me, Casper & Nova]

Shermy and Beth

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. [Come Along With Me]

non-canon information
Beth, who is pup number thirty-eight thousand and 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. [Steve Wolfhard (1) (2) (3)]

Shermy and Beth are rebels who oppose the icy rule of Gibbon, and Beth seeks to incite a revolution to overthrow him. After one graffiti campaign, Shermy begins to act strange. As it turns out, his body has been temporarily inhabited by a version of Simon Petrikov from nearly a thousand years ago. Simon and Beth visit what remains of Turtle Princess' library to seek information about this world's crown. Instead, Simon finds a choose your own adventure book about two fictional spacefaring adventurers named Casper and Nova who are also looking for the crown. Through them, he comes to understand that his relationship with Betty was not entirely symmetrical, and that his singular focus on his own work caused her to voluntarily neglect her own dreams. Having come to this understanding, Shermy is restored to his own body and Simon is sent back to the past. [Casper & Nova, Cheers]

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. [Come Along With Me]

After BMO finishes his story, Shermy and Beth venture out to go and find the tree that grew from Fern's seed, on the former site of the Tree Fort. It has grown to enormous size, stretching high into the clouds. The two adventurers climb the tree and obtain the Finn Sword, becoming the first to wield it in a thousand years. [Come Along With Me]

The Graybles

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. [Graybles 1000+]

non-canon information
Some accounts suggest that Cuber was alive during the events of the series. This is probably false. [The Adventure Time Encyclopaedia, Graybles Schmaybles]

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. [Five Short Graybles, Five More Short Graybles, Another Five More Short Graybles, Graybles 1000+, Five Short Tables]

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. [Graybles 1000+]

non-canon information
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]

Billions of years in the future

The Sun Blows Up

Death once claimed that Simon would continue to exist as the Ice King until this time, but this has since been proven false. [Betty, Come Along With Me]

THE END

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.
