Minor Characters of ''WesternAnimation/AdventureTime''.

!!Candy People

An inhabitant of the Candy Kingdom, distinguished by his hat, mustache, and the fact that he's a ball of starch. Starchie works as a gravedigger and runs his own late-night radio talk show.

-->Voiced by: Creator/TomKenny

* TheCuckoolanderWasRight: Turns out [[spoiler:he was right about PB being replaced by a lizard imposter in "We Fixed A Truck".]]
* FakingTheDead: Faked his death and ran away to get away from Princess Bubblegum's intrusive surveillance. She then had him cloned.

* {{Gasshole}}: Squeeze him and he'll fart.
* GoneHorriblyRight: The Ice King's pained howls free him from the Freezer Burn Flu, and after saying he feels healthy again, he immediately bulks up even more.

* LivingPolyhedron: As you'd expect from a living tapioca pearl.

[[folder:Mr. Cupcake]]

The strongman of the Candy Kingdom, Mr. Cupcake is, as his name suggests, a giant cupcake.

-->Voiced by: Creator/DeeBradleyBaker

* BadassMustache: He sports a handlebar one.
* FeelNoPain: In an attempt to avoid going and living with Lemongrab for a few weeks so he wouldn't be so lonely, Mr. Cupcake broke his own arm. The only sound he made during the whole thing was a single grunt, which sounded more from effort.
* NakedPeopleAreFunny: In "Slumber Party Panic", while playing Truth or Dare, Chocoberry dares him to take off his wrapper.
* SesquipedalianLoquaciousness: Very well spoken.
-->'''Mr. Cupcake''': "Surely this frosted drink will soothe my fevered tempers." ''[Drinks milk shake when he hears Hug Wolf Finn]'' "Hello? Good heavens! A lycanthrope!"

* PoliceAreUseless: They rarely manage to acomplish their job protecting the kingdom. [[spoiler:Princess Bubblegum is so dissapointed by it that she assigns Root Beer Guy in charge of the Banana Guard]].
* PraetorianGuard: For Princess Bubblegum.
* YouAreNumberSix: In "The Thin Yellow Line", Finn meets one called Banana Guard 16, implying that the others are numbered as well.

[[folder:Gumball Guardians]]

A pair of giant Candy People with gumball machine heads. Initially presumed to be statues, they sit at opposite ends of the kingdom blowing bubbles. They only act in the utmost circumstances, such as [[spoiler:The Lich going on a rampage in the city]]. They are also the Guardians of the Royal Promise, punishing those who break Royal Promises. [[spoiler:They were built by Princess bubblegum during the early days of the candy Kingdom as a way to defend the candy people from the bath gang and were responsible for the death of Shoko]].

* YourHeadAsplode: They suffer this when Finn gets the math question right.

[[folder:Royal Tart Toter]]

The Guardian of the Royal Tarts, the only Candy Kingdom food worth killing for. He protected the Royal Tarts when they were escorted to the Annual Back Rubbing Ceremony, until he became senile and unable to discharge his duties. Sadly, his mental state has left him unaware of that, and he still believes he's carrying the Royal Tarts.

-->Voiced by: Creator/StephenRoot

* AxCrazy: A non-villanous (or evil) example.
* BadassMustache: Subverted, it was once badass, but then it got torn.
* MacGuffinGuardian: His job was to guard the Royal Tarts in their journey from the Candy Kingdom to the Sacred Backrubbing Ceremony.
%%* TheMentallyDisturbed
* MindScrew: The infamous "Tart Toter speech":
-->'''Royal Tart Toter''': This cosmic dance of bursting decadence and withheld permissions twists all our arms collectively, but... if sweetness can win—and it can—then I'll still be here tomorrow to high-five you yesterday, my friend. Peace.
* SeriousBusiness: Guarding the Royal Tarts was. In the title card of "The Other Tarts" shows him having to fight off several people trying to grab the Tarts.


Yet another experiment, made to counter Goliad using Finn's hair as a base. Stormo quickly proves true to his heroic roots and traps Goliad and himself for all eternity, to save the Candy Kingdom.

-->Voiced by: Henry Linehan

* BigDamnHeroes: See Dynamic Entry.

* DynamicEntry: He rushes in just in time to save Finn and the Candy Kingdom from Goliad.
* GoodCounterpart: Based on Finn's DNA rather than Bubblegum's.
* HeroicSacrifice: Locks himself and Goliad in [[SealedEvilInADuel an eternally stale-mated psychic battle.]] Truly impressive in that he doesn't even hesitate to do so.
* LikeFatherLikeSon: In a way, he ''is'' Finn’s son, being made from his DNA. So just like Finn, Stormo is every bit as noble and heroic. He also inherits Finn’s blonde hair.
* PsychicPowers: With the power of his third eye, he can manipulate objects and other beings, just like Goliad.
* SiblingYinYang: It's unclear to what extent they are siblings, but they're as different as night and day. [[spoiler:The addition of Finn's DNA into Stormo's primordial goop is the only noted difference between them.]]
* {{Telepathy}}: See Psychic Powers.
* TheUnintelligible: Speaks entirely in birdlike screeching sounds, though Goliad seems to understand what he's saying.

[[folder:Princess Cookie]]

A chocolate chip cookie orphan who wanted to grow up to be a princess, so as to spread love and joy. But Princess Bubblegum laughed when she heard this, because [[GenderBlenderName he's really a dude named Baby-Snaps]]. Eventually grew up and held a convenience store full of candy people hostage. Currently resides in a candy people mental institute.

-->Voiced by: Donald Faison

One of Princess Bubblegums many suitors, Braco is the the third generation of his family to become a suitor after his father ascended. At the age of twenty one he was the yougest suitor by far, with the oldest being over three-hundred. He looks like a normal human except for his skin color and the crystal like candy on his head.

A background character who ends up the focus of the episode "Root Beer Guy". A Candy Kingdom telemarketer and wannabe mystery writer, he spies Finn and Jake kidnapping the princess once night and investigates the case despite the concerns of his wife, Cherry Cream Soda. [[spoiler:As it turns out, the kidnapping was all staged to test the Banana Guards, who not only horribly failed the case, but had Root Beer Guy handcuffed.

-->Voiced by: Jack Pendarvis


* ADayInTheLimelight: "Root Beer Guy" is his.

A robotic gumball machine and a mysterious, masterful swordsman who lives out in a junkyard. He far surpasses Finn and the blade of grass by skill alone in their first fight. Though reluctant to train Finn at first, he agrees after Finn does him a long needed favor. [[spoiler:He then reveals to Finn that he is the last of an elite force of gumball machine police-bots that Princess Bubblegum massacred a long time ago following a mass lapse in their discipline. When Finn reveals his existence to Bubblegum, she sends a squad to the junkyard to ambush Rattleballs. He incapacitates all of them but leaves them alive, and after thus proving his skill and re-pledging his loyalty to Bubblegum, she hires him as a vigilant watch over the night in the Candy Kingdom]].

-->Voiced by: Creator/RainnWilson

* TechnicalPacifist: [[spoiler:When Bubblegum thinks he's slain her entire ambush squad, the squad is revealed to be bruised but alive, thus demonstrating both his skill and his self-control]].
* ThreeLawsCompliant: He interprets the First Law loosely (see TechnicalPacifist, above), plays the [[ICannotSelfTerminate Third Law]] straight [[spoiler:while the rest of his kind walk straight to the crusher]], but...

* IJustWantToHaveFriends: [[spoiler:The original reason that he starts faking his death- so that Bubblegum will clone him and he'll have a new friend to hang out with. After that, it just becomes about the medals.]]
* TheyKilledKennyAgain: He's died defending Bubblegum at least twenty-five times. [[spoiler:Or so it seems.]]
* WhatMeasureIsANonHuman: Bubblegum lets him sacrifice himself rather than let Finn do it, because he's made of candy and can be easily cloned, while Finn can't.

[[folder:Colonel Candy Corn]]

An retired officer in the Candy Kingdom military. [[spoiler:Commands the Banana Guards after Root Beer Guy's death.]]

-->Voiced by: Keith Ferguson

* TheStarscream: Under Colonel Candy Corn's brief dictatorship.
* TheUsurper: Twice. First from Colonel Candy Corn when Princess Bubblegum briefly disappears, and then [[spoiler: from the King of Ooo when the Candy People turn against him]]. Later we find out [[spoiler:he was one of the first candy people, who planned to betray Bubblegum, but became what he was today when Gumbald betrayed him first]].
* VocalDissonance: His voice is impressively deep and scratchy given his appearance.
* WasOnceAMan: [[spoiler:Used to be another fully intelligent bubblegum person, PB's "cousin" Chicle, but was turned into a candy person by Uncle Gumbald.]]

A candy dragon who lives in the depths of the Candy Kingdom, suckling on the roots of the candy tree and secreting candy juice that the rest of the Candy Kingdom uses for bathing and healing. He's also Princess Bubblegum's brother.

-->Voiced by: Andres Salaff

* AmbiguousDisorder: Despite being a huge candy dragon, Neddy is reclusive and has a crippling fear of anyone and anything who isn't his sister Princess Bubblegum. Apparently, this is the result of his first experience when being "born" was landing painfully on a sharp rock, presumably associating the outside world with danger and pain. PB is well aware of how different Neddy is from most people:
-->'''Princess Bubblegum''': People are built different. We don't need to figure it out, we just need to respect it. Maybe he likes his own company better than I like mine.
* ImmortalImmaturity: He's a little younger than Bonnie, but acts very much like a very young frightened child. His sister keeping him in isolation probably contributed to it. He's very fearful of the outside world and is only happy when sucking on the roots of candy trees and being with Bonnie relaxes him.
* MadwomanInTheAttic: PlayedWith; Princess Bubblegum keeps him hidden away, not because she's embarrassed of him, but to keep him safe since he's so sensitive and so terrified of everyone and everything. He really just wants to be left alone to suck on the candy tree roots, which lets him provide the Candy Kingdom with precious candy juice to keep them healthy and clean. Despite this, there was a rumor among the Banana Guards that PB kept him chained up (though this further implies that Neddy's existence isn't even secret). Apparently, [[spoiler: PB's artificial family she made was aware of Neddy and she made them in order to have someone like her to talk to, implying she was a bit overwhelmed when dealing with him when she was younger. Nonetheless, she still loved him and got ''pissed'' when Gumbald threatened him]].
* OurDragonsAreDifferent: He's huge and made of gum, for one thing. He also has tiny wings, his eyes are below his mouth, and he secretes precious candy juice by suckling on the roots of the candy tree.
* PoweredByAForsakenChild: The whole kingdom runs on the juices he secretes. He's not really forsaken as much as hiding from the outside world due to being afraid of basically everything that isn't Princess Bubblegum.

* EyesAlwaysShut: Her eyes only open a few times.
* LarynxDissonance: She's voiced by a man, rather like her best friend LSP.

* BewareTheNiceOnes: Dear lord, don't let her timidness fool you. If she perceives herself as insulted, she will ''not'' take it well.[[note]]Unless she gets a written apology[[/note]]
* DistressedDamsel:

* PlanetOfHats: The Wildberry Kingdom: a kingdom where everyone is a berry.
* PrincessesRule: Apparently the only ruler of the Wildberry Kingdom.

[[folder:Hot Dog Princess]]

A princess who rules over the Hot Dog Knights.

--> Voiced by: Maria Bamford

* AbhorrentAdmirer: After Finn saves her, she tries to kiss him. However, he doesn't want to get kissed by her because he says that she smells like "old hot dog water".
* CloudcuckoolandersMinder: Instead of the knights protecting their ruler, most of the time it's the other way around.
* DistressedDamsel: She requires saving pretty regularly. Her knights are ''even worse''.
* PrincessesRule: Apparently the only ruler of the Hot Dog Kingdom.
* VisualPun: Instead of actual hot dogs, she and the Hot Dog Knights look like a cross between hot dogs and dachshunds--which makes them literal "wiener dogs".

-->Voiced by: Maria Bamford ("[[Recap/AdventureTimeS4E24ReignOfGunters Reign of Gunters]]"), Creator/JennySlate ("From [[Recap/AdventureTimeS7E24FluteSpell Flute Spell]] and onwards")

* ActionGirl: Of course. Why else would she have such a name?
* AmbiguouslyBi: In "Wizard Battle" she is the only female wizard not turned off by the fact that the prize was kissing Princess Bubblegum (although WordOfGod stated that she probably stayed for the {{challenge|Seeker}} alone).

* [[SecondLove Third Love]]: For Finn.
* VisualPun: She literally sleeps like a log.

!!The Lemongrab Earldom
[[folder:Lemongrab 2]]
Lemongrab's clone. Created by Princess Bubblegum for the purpose of giving Lemongrab a companion.

-->Voiced by: Creator/JustinRoiland

* ButtMonkey: [[spoiler: Not initially, but by "Too Old", he had become this to the original Lemongrab.]]
%%* ClonesArePeopleToo
* CloningBlues: Lemongrab 2 was created to be a companion to the first one, and, despite their obnoxious personalities, are [[SubvertedTrope actually both very happy together with their family]] [[spoiler:[[DoubleSubversion until "Too Old"]].]]
* ColorCodedCharacters: To differentiate between him and Lemongrab, one wears grey and the other wears white.
* DefectorFromDecadence: [[spoiler:Lemongrab 2 in "Too Old" is rebelling against Lemongrab 1.]]
* DivergentCharacterEvolution: At first, Lemongrab and Lemongrab 2 are essentially the same in every way. In "Too Old" they're shown to have become different, but with disastrous consequences: though Lemongrab 2 has become nicer and learned the error of his ways, Lemongrab has taken ''major'' [[TookALevelInJerkass levels in cruelty]] and insanity.
* GoodParents: As evidenced in "All Your Fault" ([[BumblingDad despite him not really thinking through the situation he and his brother were creating for their new family, not just themselves]]), "Another Five Short Graybles", [[spoiler: and especially Too Old, Lemongrab 2 is a loving father to his many children, starkly contrasting the [[AbusiveParent direction]] Lemongrab 1 wound up going. This is most clearly ([[TearJerker and depressingly]]) demonstrated when he shares his food with one of his children, who'd just had his taken away, despite clearly being starved and sickly himself]].
* HairTriggerTemper: Though downplayed compared to his clone. [[spoiler: In "Too Old" it's nearly nonexistent, presumably because he's very, very weak from hunger and from being sick.]]
* HandicappedBadass: He later suffers from the loss of his legs, most of his health, and half of his head. That doesn't stop him from being a hero and a martyr for the cause of the lemon people.
** Well, he would have been a martyr, ''if he didn't survive inside of his brother's stomach''.
* HeroicSacrifice: [[spoiler: He takes away Lemograb's ear plugs and tells Lemonhope to keep playing, even when he ''knows'' that this will result in his own death.]]
* JerkWithAHeartOfGold: In his earliest appearances, he comes across as being mildly annoying, but unlike the original [[AxCrazy Lemongrab]], that's the only problem he appears to have, and he still did things like [[PetTheDog immediately suggest to pardon the prisoners after meeting and bonding with his brother.]] The "jerk" part seems nonexistent by the time of "Too Old", as he's nothing but nice and generous throughout the entire episode, and in "Lemonhope Story", he [[spoiler: commits a HeroicSacrifice for his children's sake.]]
* KilledOffForReal: [[spoiler:So it seemed in ''Too Old'', but he survives inside Lemongrab's stomach for ''Lemonhope Story''. He actually dies when his brother explodes, but Bubblegum integrates the remains of both Lemongrabs into a single Franken-Grab at the end]].
* MoralityPet: Formally to Lemongrab. Grossly averted in "Too Old."
* NakedOnArrival: The first time we see Lemongrab 2, he's butt naked.
* OnlySaneMan: Well, compared to his clone in "Too Old", anyway. It's a fact that almost all of the lemon people (with the exception of Lemonhope) are totally nuts. The difference between Lemongrab 2 and Lemongrab is that Lemongrab 2 is very kind while his brother is not. Lemongrab 2 is definitely crazy, but not violent or a bad person.
* PapaWolf: To the bitter end.
* TookALevelInKindness: He was never a ''bad'' guy, but he was something of an intolerable, annoying prick, just like Lemongrab. He eventually stopped being quite as annoying, and became genuinely polite and friendly, even selfless.
* VocalEvolution: Over time his voice has gotten less cacophonic, and his speech styles more coherent and eloquent, such that by the time of Lemonhope Part 2 it's lost most of the jarring qualities that simultaneously became more exaggerated in Lemongrab 1. It emphasizes his character evolution into OnlySaneMan and selfless PapaWolf.


The eldest of the Lemongrabs's children. A lemon giant with a booming voice, he proves himself early on to be more sensible, and helpful, than his fathers. [[spoiler:He even sacrifices his own life to protect his family and all of the Candy People]]. In the words of Finn, Lemonjon is "all right."

-->Voiced by: Creator/JustinRoiland

* AmbiguousDisorder: He's awkward, has difficulty in processing and articulating his emotions, and has an unconventional manner of speaking. There's also the fact that he had a rather serious case of [[spoiler:cardiac arrest, which was only resolved when Finn and Jake punched his heart]].
%%* BigDamnHeroes: Literally.
%%* ChildrenAreInnocent: ''Oh yeah''.
* CloudCuckoolander: Not to the same extent as the earls, but he ''is'' a pretty strange dude.
* DarkIsNotEvil: His appearance is disturbing and he's pretty damn [[{{Gonk}} ugly]], but he's a downright wonderful guy.
* FinalSpeech: Gives a beautiful, eloquent, and heartbreaking one just before [[spoiler:he dies]].
--> '''Lemonjon:''' Whoa, hold the phone! What is this powerful new juice coursing thrumpst my core source? The juice aches. Is this the rumored ache of feeling? The feeling of caring unknown to lemons? New thoughts emerge... If I act, the candy people will suffer; if I don't, the lemon people will suffer! [[spoiler:The greater good demands but one course only! That I dissolve the bonds uniting me and become component to all]]!
* FirstTimeFeeling: "Is this the rumored ache of feeling? The feeling of caring unknown to lemons?"
* FunnyAfro: The lighter-colored, fluffy lemon candy piled atop his head gives him this appearance. It resembles a big perm divided into three slightly spiked-up sections.
* GagNose: He has ''two''. Why the Lemongrabs thought it was essential that Lemonjon have two noses has not been explained.
* GentleGiant: Absolutely. He's one of the largest Candy People ever to exist, and he's also perhaps the most selfless.
* TheGiant: He's as big as the whole castle, and is the castle, kind of.
* GiantMook: The Lemongrabs attempted to use him as this.
%%* {{Gonk}}
* HeartTrauma: Finn and Jake [[spoiler:punch his heart to attempt to kill him. Instead, this causes his heart to start beating, resulting in Lemonjon having an epiphany]].
* HeelFaceTurn: While he was never a villain, he seemed neutral, yet still willing to attack the Candy Kingdom. But he eventually TookAThirdOption [[spoiler:which resulted in his own death]].
* HeroicSacrifice: To save his family and the Candy People.
* KilledOffForReal: The second important character to [[spoiler:suffer the fate of permanent death]]- the first was [[spoiler:Billy]].
* LargeHam: " '''Mmmmmm... MENAGERIE!''' "
* LikeFatherLikeSon: "Three weeks dungeon." He seems to have inherited the pedantic speech of his fathers.
* LiteralChangeOfHeart: His heart actually [[spoiler:awakens]] when Finn and Jake punch it.
* LivingStructureMonster: He's so big he takes up the whole castle, and is essentially part of it.
* MoralDilemma: "If I act, the Candy People will suffer! If I don't, the lemon people will suffer!" He eventually takes a third option that saves everyone's lives [[spoiler:but his own]].
* TheNeedsOfTheMany: [[spoiler:His reasoning for his HeroicSacrifice.]]
* NoIndoorVoice: In a different way than the Lemongrabs. While the Lemongrabs are very shouty, Lemonjon tends to speak much more calmly, and doesn't yell. But Lemonjon is very loud, because he's a literal giant. He can't really help it.
* TakeAThirdOption: He [[spoiler:explodes and reverts to lemon candy to feed his starving family rather than attack the Candy Kingdom to steal their food]].
* {{Telepathy}}: He seems to have this ability. When Finn and Jake asked him about the location of the earls, Lemonjon closed his eyes, and said in a strained voice that he "sensed" that they were in the dungeon.
* TooGoodForThisSinfulEarth: "Man... That Lemonjon [[spoiler:was all right.]]"
* TorturedMonster: Although the Lemongrabs view him as a child, they did attempt to use him as a [[PersonOfMassDestruction weapon]]. And when he's slowly standing up, after months of literally being attached to the ground, he sounds like he's in pain.
* WackyParentSeriousChild: He seems much more down-to-earth and reasonable than his dads.
* WhatIsThisFeeling: Mentions this trope in his [[spoiler:final]] speech.
* YoungerThanHeLooks: He's a giant and he has a low, booming voice. But the Lemongrabs say that Lemonjon is "young," and only a child. [[spoiler:Which makes his untimely and sudden death all the more heartbreaking]].

[[folder:Lemon Children]]
The strange-looking and eccentric, toddler-aged children of the Lemongrabs. They reside in Lemon Castle, and there seem to be dozens of the [[FreezeFrameBonus little pooters]].

-->Voiced by: Creator/JustinRoiland

* AffectionateNickname: According to the screenshot of Lemongrab’s brain, the earls affectionately call their babies “little pooters.”
* AmazingTechnicolorWildlife: The Lemon Children are a strange combination of person, plant, animal, and fungi- and they’re all various shades of yellow, orange, and green.
* AmbiguousDisorder: They all seem pretty “off,” but it hasn’t been made clear if they’re as bonkers as their dads yet.
* BabiesMakeEverythingBetter: According to the Lemongrabs.
* BabyTalk: The only word we could hear them say was “hungry” and "candy." For the most part, they just babble and shriek.
%%* BigScrewedUpFamily: Oh, ''yeah''.
* BodyHorror: Some of the Lemon Children are rather grotesque- limbless, disfigured faces, lumpy and misshapen.
* CarnivoreConfusion: When they are starving, they attempt to eat Finn and Jake. However, it strangely never occurs to them to eat each other, even though they are all mostly made of candy themselves.
* ChildrenAreInnocent: Toyed with. They seem to mostly be toddlers, but they’re enthusiastic about their dads’ plan to take over the Candy Kingdom.
* CloudCuckoolander: Obviously, given who their progenitors are.
* ConjoinedTwins: Some of them.
* CreepyChild: Finn and Jake seem to think this about some of the Lemon Children, especially the one whose face pealed back.
* CuteButCacophonic: Many of the Lemon Children are rather adorable in appearance, but they have high-pitched, shrieking voices.
* DysfunctionalFamily: Let's just say, they're about as functional as the [[WesternAnimation/FamilyGuy Griffins]] if they were all three times as insane, and lemons.
* EyelessFace: Some of them don't have eyes ''or'' faces. In fact, some of them are just lemons with wings attached.
* GagNose: Several of them have the long, pointy noses of their dads. Others have big, bulbous noses.
* {{Gonk}}: Some of the Lemon Children could be considered to be quite ugly.
* GreenEyes: The Lemon Child with the pealing face has green eyes.
* GrotesqueGallery: They're all twisted and lumpy.
* HasTwoDaddies: They are Lemongrab and Lemongrab 2's children, but regardless, they're a big happy family.
* ItRunsInTheFamily: Some of them seem pretty “special.”
* LastMinuteBabyNaming: The earls seem to name their children at the last minute. ''Seconds'' after they brought the candy seeds to life, Lemongrab jubilantly yelled, “Ha-HA! We’ll call you SEED-WAD!”
** The earls still haven’t decided whether their second-youngest child is named “Plop-Top” or “Dump-Dome.”
* LetsHaveAnotherBaby: The earls probably said this to each other at some point, and it just kept happening, over and over again…
* LikeFatherLikeSon: Many of them have the same eyes as their fathers, and many of them resemble lemons in some way.
* MassiveNumberedSiblings: Well... there ''are'' over twenty of them.
* NiceShoes: The multi-mouthed lemon child has a pair of little [[RealMenWearPink hot pink cowboy boots]].
* NippleAndDimed: Several of the Lemon Children have nipples and visible breasts (due to being chubby babies.)
* NoIndoorVoice: Possibly due to being children, possibly due to being the sons of the Lemongrabs. In one scene, Plop-Top, who had been sitting calmly the whole time, randomly opens his mouth to emit a high-pitched, piercing shriek. He then resumes looking calm.
* OneGenderRace: According to the Lemongrabs, all of their children are male.
* PettingZooPeople: They range from being strange-looking people to being anthropomorphic to looking like actual ''animals''.
* PintSizedKid: Some of them.
* PlantPerson: Some of the Lemon Children resemble plants or mushrooms.
* RoyallyScrewedUp: Assuming the Lemongrabs are brothers.
* SharedFamilyQuirks: Their tendency to scream at random intervals. Apparently, the earls view the screams of their children as “piercing songs.”
* TheScream: They take after their fathers in this department. Seems to be a lemon trait.
* ThatThingIsNotMyChild: Adorably averted. Many of the Lemon Children are downright grotesque-looking and deformed, but the earls love every single one of them and treat them all like their babies.
* TooManyBabies: Or in this case, ''way'' too many.
* TheUnintelligible: Because of their age, they can only communicate using one-word or monosyllabic sentences, strange noises, and shrieks.
* VocalDissonance: Most of them sound like how one would imagine the children of the Lemongrabs sounding- high, shrieky voices. But the tiny Lemon Child with the pealing face has a ''very'' low voice, which he uses to bellow continuously.
** Averted when said child appears later on and he has a high, squeaky voice.
* VomitIndiscretionShot: Seed-Wad barfs all over himself after the Lemongrabs make him.
* WaveOfBabies: The Lemon Children all mob Finn and Jake in a large herd, rubbing against them and attempting to chomp on them.
* WhatMeasureIsANonCute: Invoked when one of the Lemongrabs’s babies literally turns out to be a vomiting pile of colorful mush. They act like this child is the most precious and wonderful creature they’ve ever seen.
** Played pretty straight when the only lemon child the Princess shows any interest in is Lemonhope, who's the least UglyCute and strange of all them.

One of the lemon children, who unlike the rest of his siblings, is the least disfigured and is musically gifted, which makes Princess Bubblegum take interest in him and decides to take him to the Candy Kingdom against Lemongrab's wishes. He is, however, freed by Lemongrab 2 and the rest of the lemon children, believing he can one day return and free them from Lemongrab's reign.

--> Voiced by: Creator/JustinRoiland

* BookDumb: Princess Bubblegum tries to give him an education, but it doesn't leave much of an impression on him and he later admits that he faked learning how to read. Phlannel Boxingday remarks that Lemonhope learns with his heart, not with his head.
* TheCallKnowsWhereYouLive: His attempts to run away from his debt to the Lemon People, failed because of his guilty conciense.
%%* DarkAndTroubledPast
* ADayInTheLimelight: Has his own two-part episode.
* {{Foil}}: For Finn. They're both the same age more or less, and they're both seen as champions for their kingdom. But while Finn happily lives up to the challenge, Lemonhope is like a lot of kids in that he wants to be on his own and only did the right thing once because he felt guilty.
* HasTwoDaddies: Personality-wise, he's inherited traits from both.
* IJustWantToBeFree: His reason for leaving the Candy Kingdom and not staying to rule Lemon Castle after defeating Lemongrab. Makes sense since he spend most of his life locked in a bathroom.
* ItsAllAboutMe: Played with. Lemonhope wants nothing more than freedom, even if it means going his own way and leaving his family to suffer under the hand of his abusive father. On the other hand, he also recognizes that freedom entitles others to do whatever ''they'' choose, even if it isn't to his benefit.
* {{Leitmotif}}: ''Poor little Lemonhope...Sweet little Lemonhope''
* MeaningfulName: He is believed by all the Lemon Children and Lemongrab 2 to one day bring hope to all of them.
* MessianicArchetype: For the Lemongrab Earldom.
* OnlyKnownByTheirNickname: His given name is "[=BadLemonNoHope=]", but prefers "Lemonhope" and is only called that by Lemongrab.
* OnlySaneMan: Compared to all the other lemon people (with the exception of Lemongrab 2) who are totally nuts, which is part of the reason Princess Bubblegum shows any interest in him.
* SociopathicHero: While not really a bad guy, Lemonhope is primarily driven by his desire to be free to fulfill his own wants. Only when his subconscious guilt sours that freedom is he driven to help the people he owes his happiness to, specifically to be free of his debt to them.
* SharedFamilyQuirks: When Lemonhope yells at Phlannel Boxingday to stop his ship (thinking he's seeing his siblings coming out of a monster's mouth), it devolves into one of Lemongrab's signature screams.
* TheUnfavorite: Out of all their children, Lemonhope is Lemongrab's least favorite, to the point that he's kept locked in a bathroom.
* UngratefulBastard: Doesn't show concern with how Lemongrab is treating all his siblings as punishment for helping him escape.
* WalkingTheEarth: Does this for the next thousand years after freeing Castle Lemongrab.

!!The Flame Kingdom
A mischevious creature who is an informant and ally of Finn and Jake. He is a flambit, a type of fire-creature that resembles a cat made of flame, but is so far the only flambit shown to be able to speak and use magic. He works for lumps of coal, which he eats.

-->Voiced by: Creator/TomKenny

* AndYourRewardIsEdible: Characters are shown feeding him charcoal as payment for his services.
* BalefulPolymorph: "Incendium" implies that he, and all flambits, were created from normal fire elementals by Flame Princess in one of her tantrums.
* ExactWords: "I know just the skirt! And she's ''[[PlayingWithFire way hot!]]''
* TheGadfly: He intentionally obscures his intentions and withholds information in "Incendium" to force Jake to improvise, which he finds amusing.
-->'''Flambo:''' There, I cast Flame Shield on ya's. [[spoiler:Also I spat on ya's.]]
* TheInformant: He helps Finn and Jake keep tabs on the Ice King.
* InstantRunes: When casting.
* KillItWithWater: In the video game ''Flambo's Hot Mess.''
* MundaneUtility: Finn uses Flambo to light his flamethrower in "Business Time," and Princess Bubblegum uses him to light the grill for her Science BBQ in "The Real You."
* MySpeciesDothProtestTooMuch: Flambo's fairly nice if mercenary, but supposedly everyone in the Fire Kingdom is evil.
* PlayingWithFire: It may just be an extension of his natural body, but Flambo can keep things warm and set them on fire.
* PutOnABus: [[WordOfGod Andy Ristaino]] has [[http://www.formspring.me/skronked/q/354603947761094206 stated]] that Flambo is hard to get ahold of, explaining why he's not usually around to cast Flame Shield on Finn for [[spoiler:his dates with Flame Princess.]]
* ScreamsLikeALittleGirl: Lampshades this himself after Jake rescues him in "Incendium."
-->'''Flambo:''' Bet you thought I was a dame on account of my girlish screamin'.\\
'''Jake:''' (frustrated) I ''did'' think that.
* StatusBuff: The only magic ability he's shown so far was Flame Shield, which protects mortals from fire.
* UnexplainedAccent: He may not be from the Bronx, but his accent sure is.

[[folder:Flame King]]

The [[spoiler:former]] ruler of the Fire Kingdom and father of Flame Princess. He is evil, like everyone in the Fire Kingdom.

-->Voiced by: Creator/KeithDavid

* AbusiveDad: Sure, locking his daughter in a lantern for her entire life wasn't a terribly nice thing to do, but considering how powerful and destructive she is, he had a good reason... but then [[spoiler:''Earth and Water'' reveals that the lantern was actually Plan B. His first idea upon learning how powerful she was as a baby was to leave the newly born Flame Princess in the wilderness to die, not because he cared about the destruction she might cause, but because he was afraid she would usurp him.]]
* {{Acrofatic}}: Subverted, it seems like it on the surface, but when you take into consideration that fire doesn't really have weight and the only thing holding him down is his armor it starts to make more sense.
* AffablyEvil: He's quite polite for an EvilOverlord.
* BadBoss: Was fine with "Finn" killing his court jester and in [[ComicBook/AdventureTimeGraphicNovels Playing With Fire]] he chastised his cook for dinner being ready 10 minutes early.
* CainAndAbel: [[spoiler:He extinguished his own brother to become King.]]
* CardCarryingVillain: He may not be of the diabolical LaughingMad variety, but he's still pretty open about the fact that he's evil.
* EvenEvilHasStandards: [[spoiler:Evil though he may be, apparently letting Flame Princess destroy the entire planet is a little too much for him, so he followed Princess Bubblegum's advice on locking her up. Later subverted since it turns out that he didn't really care about the destruction his daughter might cause; he only locked her in there so she wouldn't take his throne from him.]]
* EvilIsBurningHot: The ''Flame'' King, anyone?
* EvilOverlord: He rules over the Flame Kingdom.
* EvilParentsWantGoodKids: Inverted (sort of) since his definition of "good" is evil. So he sneaks into Flame Princess's house through her scented candle flames and starts whispering in her ear..
--->'''Flame King''': Evil. Evil evil evil. Evil evil evil evil!
* EvilSoundsDeep: Comes with being voiced by Creator/KeithDavid.
* ForTheEvulz: [[ComicBook/AdventureTimeGraphicNovels Playing With Fire]] shows him terrorizing the citizens of the Flame Kingdom just because he can.
* JerkWithAHeartOfJerk: While he no longer acts hostile towards Flame Princess and even supports her during her rap battle in "Son of Rap Bear", he also refuses to apologize for how he mistreated her or even acknowledge any wrong doing on his part.
* KlingonPromotion: [[spoiler:He became the king by killing his older brother. Later on, he's on the receiving end of this trope when his daughter takes control.]]
* LargeAndInCharge: He's a big dude, to say the least.
* OrcusOnHisThrone: Just sits around in the Fire Kingdom, despite the rest of Ooo being inflammable and presumably ripe for conquest. Could apply to the Fire Kingdom people in general. On the other hand the rest of Ooo also contains a large amount of water, which has been shown to be fatal to Flame People, making a full scale invasion costly at best and suicidal at worst.
* SealedEvilInACan: [[spoiler:Usurped by his daughter and put inside the same lantern he put Flame Princess in.]]
* TookALevelInKindness: Sort of. While still a jerk, he at least attempts to support Flame Princess in "Son of Rap Bear" and no longer wants to dethrone Flame Princess; now content with peacefully ruling a chipmunk kingdom alongside Bun Bun.

!!The Duchy of Nuts
[[folder:The Duke of Nuts]]
!!The Duke of Nuts
[[caption-width-right:120:"[[GettingCrapPastTheRadar Why would you want to sack MY Nut Castle on my second son's first birthday?]]" ]]
The Duke of Nuts is a generally nice member of royalty, ruling over the Duchy of Nuts. An all-around family man, his only major flaw is that a physical deficiency makes him uncontrollably eat any pudding in range.

--> Voiced by: Steve Little

* {{Adorkable}}: He's nice up to the point of being awkward. When he thanks Finn and Jake for waiting for him, he ''gives them daisy chain crowns'' as a token of his appreciation for waiting him.
* TheBusCameBack: Returns in the GrandFinale as part of Princess Bubblegum's army.
* ChuckCunninghamSyndrome: Hasn't appeared or been referred to since the first season. Probably because he's just too nice a guy to be that interesting, and because Princess Bubblegum having an irrational and emotional grudge against him shows her to be flawed in a very different way to [[TotalitarianUtilitarian the one]] which they would later explore.
* HappilyMarried: His wife quickly jumps to his defense in the pudding case. Also, he 'lies with her' often.
* NiceGuy: ''Ridiculously'' nice. Almost ''obscenely'' nice. Hell, he was willing to take the fall for Finn even though he was totally innocent.
* PokeThePoodle: About the only thing he's ever done wrong is eat all of Bubblegum's pudding.
* QuirkyHousehold: Him and his family are pretty weird, but love each other. His wife is nuts, in both the figurative and literal sense of the word.
* SitcomArchNemesis: To Princess Bubblegum, who despises him solely because he ate all of her pudding once.
* SweetTooth: He loves him some pudding.
* TrademarkFavoriteFood: Pudding.

[[folder:The Duchess of Nuts]]
!!The Duchess of Nuts
[[caption-width-right:269:"The nuts told me, for I am the Duchess of Nuts!"]]
The wife to the Duke of Nuts, and the matriarch of the Duchy of Nuts' royal family.
* AxCrazy: While it can be partially chalked up to her concern for her husband, she still comes across as deeply unhinged during her conversation with Finn.
* MaybeMagicMaybeMundane: She claims to be capable of communicating with her bowl of peanuts, but we are never given any sort of confirmation either way. Although if not, then that does raise the question of how, exactly she was aware of Finn and Jake's plan to arrest the Duke.

!!Jake and Lady Rainicorn's Puppies
[[folder:General Tropes]]

* BadassFamily: After two days they were more capable in a fight than their (admittedly sleep-deprived) father.
* EverythingsBetterWithSpinning: Their fused form spins rapidly to attack.
* FusionDance: In "Jake The Dad", to fight the foxes that were trying to eat Jake, the five of them are shown to combine into... something. They can even involve Jake in it, without him requiring any understanding of what was going on.
* NonHumanHumanoidHybrid: Half-rainicorn, half-magic dog. [[spoiler:well quarter dog and quarter [[EldritchAbomination something else]].
* RapidAging: They become adults in ''less than a '''week'''''.
* UnevenHybrid: [[spoiler: One half rainicorn, one quarter dog, one quarter whatever it was that [[FaceFullOfAlienWingWong impregnated]] Joshua]].

[[folder:Jake Jr.]]

One of Jake and Lady Rainicorn's puppies, who inherited Jake's mischievous side.

-->Voiced by: Creator/KristenSchaal

* EyelessFace: Unlike the other pups, she doesn't have visible eyes or a nose. She does have several wrinkles on her face, but exactly what they are or why her face is like this is unclear. She also has an unusual mouth which appears to open both horizontally and vertically, and her horn is on her lower back. [[spoiler: Turns out her odd face may be inherited from her extra-dimensional "grandfather".]]
* GenderBlenderName: She's a girl named Jake.
* InTheBlood: [[spoiler:She has recently become a thief like her father was in his youth.]]
* RapidAging: Despite being less than a year old chronologically, she stated in her second appearance that she was 22, then in the very next episode, she was "basically" 30.
* VoluntaryShapeshifting: Her hair can grow and be controlled in the same way her father controls his body.
* WackyParentSeriousChild: In "Another Five More Short Graybles".
* WellDoneDaughterGirl: She wants Jake to be proud of her. [[spoiler:He is... especially after she demonstrates what a skilled criminal she is.]]
* WhatDoesSheSeeInHim: Believes her mother has strange taste in men.


Another of Jake and Lady's puppies. He still lives with his mother.

* CannotTellFictionFromReality: He hallucinates that the events in BP's diary are happening to him.
* GeekPhysiques: He's the chubbiest of his siblings.
%%* HollywoodNerd
* ManChild: He's the same age as Kim Kil Whan, but acts like a teenager.
* MommasBoy: In the sense that he still lives with Lady (and uses her shampoo), but he also seems the closest to her out of all the pups. At the end of "Lady Rainicorn of the Crystal Dimension", he tells her he wants to "learn to be cool, like you."
* MrImagination: He imagines himself as part of BP's diary.
* RapidAging: Like the rest of the puppies, though he still acts the most childish.

[[folder:Kim Kil Whan]]

* CorruptCorporateExecutive: He buys out his father's treehouse and splits it into thirty-seven tiny apartments that he rents out.
* FoolishSiblingResponsibleSibling: The responsible sibling to Jake Jr. and TV's foolish siblings.
* InterspeciesRomance: He's married to a bear, and they have a daughter.
* JerkWithAHeartOfGold: He's not a bad guy, but he's kinda a large jerk to his father in the course of trying to teach him responsibility.
* {{Landlord}}: Becomes this to Finn and Jake, buying their treehouse out from under them.
* RapidAging: Even more noticeable than his siblings. He has a beard by three days old.
* RulesLawyer: Jake digs up a golden bone in his yard to buy back the treehouse. Kim Kil Whan reasons that since the yard is his property, the bone already belongs to him.
* TookALevelInKindness: Kim does grow more patient with his dad. In his second episode, we see him participating in a three legged race with Jake before asking him for help with his daughter.
* WackyParentSeriousChild: He is extremely responsible, and resents his father's laid-back lifestyle.


Another of Jake and Lady's puppies.

-->Voiced by: Paget Brewster

* DaddysGirl: Thinks Jake is the best father in the world, despite hardly ever seeing him, and is the only one of Jake's kids who respects him after RapidAging.
* TheDogBitesBack: At LSP.
* ProperLady: She speaks in a very posh manner. Except around her dad.
%%* RapidAging


The last of Jake and Lady's puppies.

* {{Sizeshifter}}: Charlie appears to have inherited this ability from her dad. She is able to grow almost as large as Ooo.
* StrongFamilyResemblance: Without her rainicorn attributes she'd look almost identical to Jake, just with freckles and a lighter shade of yellow fur.
%%* YouthfulFreckles

-->Voiced by: Rae Gray

* BrattyTeenageDaughter: Would rather go skateboarding than focus on her schoolwork.

* NonHumanHumanoidHybrid: Where to ''begin?'' She is half bear from her mother's side while Kim is of course, half rainicorn from Lady and half dog from Jake while [[spoiler: Jake himself is technically half dog and half extradimensional creature, thus, all of his kids would be one quarter dog and one quarter alien being, thus Bronwyn is half bear, quarter rainicorn, 1/8th dog and 1/8th alien]]
* RapidAging: Less than a year old, but she's already a teenager.
* ShockAndAwe: Has the ability to turn into electricity.

* ActionGirl: Margaret, who forms half of Joshua and Margaret Investigations, definitely qualifies. She seems to favor a crossbow and shuriken.
* BadassNormal: By [[FunnyAnimal Ooo's definition of normal]], anyway. Neither of them have stretchy powers like Jake, but are shown to be able to handle enemies powerful enough to beat their super-powered sons easily.
* BattleCouple: They're HappilyMarried and both of them work together in their monster hunting business.
* CoolSword: Joshua was the original owner/creator of the [[InfinityMinusOneSword Demon Blood Sword]].
* DeceasedParentsAreTheBest: Played with; though flashbacks show that they had their shortcomings (Margaret insisted on following a guide to raising their children that kept them from even the smallest dangers and Joshua encouraged his sons to beat each other up in order to be "tough galoots"), Finn and Jake still remember them fondly.
* FaceFullOfAlienWingWong: [[spoiler:A monster bit Joshua and implanted an egg in his head, which resulted in Jake's birth.]]
* GoodParents: Played with: Margaret insisted on strictly following a guide on how to raise children, refusing to expose her sons to even the slightest risk, while Joshua was a strict father who wanted his children to be "tough galoots". However, both of them do love their children very dearly despite these shortcomings.
* KleptomaniacHero: As ''Jermaine'' reveals Joshua stole ''alot'' of stuff from demons... and the demons want their stuff back.
* HappilyMarried: While they have their disagreements, they clearly love each other and have a stable married life.
* LookalikeLovers: They look very similar to one another, with the only things that differentiate them being their hats and Margaret's earrings [[TertiarySexualCharacteristics and long eyelashes]].
* MotorMouth: Joshua tends to talk like this.
* MisterSeahorse: [[spoiler:Joshua is the one who gave birth to Jake, who popped out of his head after he got bitten by a monster.]]
* {{Posthumous Character}}s: Both are dead by the time of the first episode, but they appear in flashbacks.
* PregnantBadass: Although her pregnancy prevents her from being as deadly as usual, Margaret manages to defeat the monster who bit Joshua by herself.
* ScarsAreForever: The reason why Joshua always wears a fedora is to hide a scar he got from [[spoiler:giving birth to Jake through his head]].
* WouldHurtAChild: DoubleSubverted by Margaret: When she's under the impression that [[spoiler:the monster she needs to defeat in order to save her husband is a baby]], she starts to apologize... then socks it in the face to take its venom.

Finn and Jake's third brother. He appears early on in flashbacks, but doesn't appear in person until "Jermaine".

-->Voiced by: Creator/JohnDiMaggio ("Crystals Have Power"), Tom Schlarpling ("Jermaine" onwards)

* BadassNormal: Despite not having powers, he holds his own when it comes to dealing with demons.
* BigOlEyebrows: Pretty much the only thing that makes him visually distinct from Jake.
* CoolBigBro: Shows Jake his love and support when Jake comes to visit him in ''Abstract'' and helps Jake get past his denial over his revelations and changes. He says that Joshua did inform him about the potential changes, but that he would've been there for his brother anyway.
* TheDutifulSon: Spends his life watching over their father Joshua's stuff, and is jealous of the adventurous life that Finn and Jake lead. Subverted, when Jake points out that he could have left any time he wanted, and Jermaine agrees that he "built his own cage".
* FoolishSiblingResponsibleSibling: The responsible one in the family.
* GreenEyedMonster: Gets in a fight with Jake over his jealous that Jake was their father's favorite, while he was left to take care of their father's stuff.
* MiddleChildSyndrome: Never explicitly stated, but adds up to the sibling birth order revealed in "Joshua and Margaret Investigations" and to Jermaine's issues towards his brothers (see TheResenter below).
* TheResenter: Has a lot of pent-up resentment towards his brothers. He gets over it in his titular episode.
* TookALevelInCheerfulness: He's alot happier now that he's free to do what he wants. He has become a landscape painter though has shifted to abstract painting (something which bothers Jake, since he's know him for painting landscapes.)

[[folder:Mr. Pig]]

A pig who used to eat people for the mob. Now married to Tree Trunks, [[spoiler:and the adoptive father of the Lich.]]

-->Voiced by: Ron Lynch

* ApologeticAttacker: "Uh, I'm sorry y'all. They're making me do this. I'll try to make it quick."

* GoodParents: [[spoiler:To the infant Lich. Whether this will actually do any good remains to be seen.]]
* InterspeciesRomance: With Tree Trunks.

* TalkingAnimal: One of the many that populate Ooo.


Shelby's little brother (actually a piece of his tail-end that got cut off performing "parkour" and landing on some string at a party.

-->Voiced by: [[WesternAnimation/TheMarvelousMisadventuresOfFlapjack Thurop Van Orman]]

* DoesThisRemindYouOfAnything: The party that led to his creation in the first place, along with the fact that Shelby passes out and wakes up from said party not remembering what happened.
* {{Expy}}: He shares many Similarities with Nintendo's Franchise/{{Kirby}}, both are small, round, pink, baby-like characters that go on an adventure blissfully to defeat a nightmarish villain.
* TheHero: To the little people living in the tree.
* MaybeMagicMaybeMundane: Kent just sort of comes into being, and its unknown whether or not this just happens with a worms body pieces being cut, or if there was some outside influence behind his.
* SortingAlgorithmOfMortality: Lampshades that he has no real sense of mortality, and slides between areas 1 and 2 of the scale.
* {{Troll}}/TroublingUnchildlikeBehavior: His parting words to Jake are, and quote ''Someday, you'll be Kent's food.'' end quote; afterwards he scoots away laughing goofily. He seems to have grown out of it rather quickly though.

!!Friends and Allies

-->Voiced by: Vincenzo Rauso (Season 1), Collin Dean (Season 5 & 6)

* ArchEnemy: He considers Finn to be his.
* AxCrazy: Finn can't even get Tiffany to stop trying to stab him long enough for them both to fight giant worms.
* TheBusCameBack: He's used for a one-off joke in "My Two Favorite People", and doesn't return again until "One Last Job", where he gets a much larger role.
* CrazyJealousGuy: He wants to be Jake's best friend again, and he will let nothing stop him.
* DelusionsOfEloquence: He makes a lot of long, flowery speeches, but they're entirely meaningless and he has to write them down on his arm so he doesn't forget the words.

* EvilCounterpart: Finn's.

* NeverFoundTheBody: [[spoiler:He gets eaten by a giant worm in "Dentist", but it's implied that he's still alive. This is confirmed in "Preboot", when he shows up as a {{Cyborg}}; however, the episode ends with the ship he's on exploding. Finn nevertheless says to Jake that he's "probably" okay to spare Jake's feelings.]]
* PermaStubble: PlayedForLaughs, as his stubble is simply pubescent peach fuzz.
* TheRival: To Finn.
* StalkerShrine: He has one of these devoted to Jake.
* TheToothHurts: He lost all of his teeth biting into the Baker's Shard.
* VagueAge: Looks and sounds about Finn's age and is a bit shorter than him, but apparently ran with Jake back when he was criminal, which is implied to have been a while ago.
* VocalDissonance: He's a conniving, murderous criminal with a penchant for villainous monologuing, but he has the voice of a little kid.

[[folder:Choose Goose]]
An anthropomorphized goose with extremely wobbly neck and limbs who speaks mostly in rhyme and sells all kinds of adventuring gear. Choose Goose sometimes teases Finn to manipulate him into buying his wares, but is mostly on good terms with him and Jake.

-->Voiced by: Chuck [=McCann=]

* AwesomeMcCoolname: Given how his middle name means "master", he qualifies here.
* BusCrash: [[spoiler:AMO claims to be Moe after going fully cybernetic, but he actually killed the real Moe.]]
* CoolOldGuy: We're talking about the guy who built BMO! And thousands more robots!
* GeniusCripple: Can't use his legs and requires his robots to carry him and for life support.
* TheMentor: Moe is a kindly father figure who tries to teach his creations life lessons and help them find their purpose.
* NiceGuy: Moe is almost endlessly kind and caring.
* {{Transhuman}}: When asked by Finn if he was human, he answered "My skin is human," implying that he has survived since the Great Mushroom War as a {{Cyborg}}.
* WhereDoesHeGetAllThoseWonderfulToys: For a lot of Ooo, Moe is the answer to this question. Much of the advanced technology still left in Ooo appears to run on Moe's systems, and in several cases Moe has been subtly hinted at being the source of other developments. For example, one flashback shows Moe with a blueprint of the Sleeping Fire Giants that are so important to the Fire Kingdom, and the flashback also includes one of the flame giants in the process of being built just outside Moe's office.


Billy's ex-girlfriend who appears in the fifth-season finale "Billy's Bucket List"

* GreenSkinnedSpaceBabe: Well, green-ish. With pointed ears for extra alien-ness.

* StatuesqueStunner: She's 20 feet tall and gorgeous.

[[folder:Breezy the Bee]]

A Female Bee that Finn meets after his final confrontation with The Lich. At first, she only seems interested in the flower growing [[spoiler:from his armless stump]] - being Finn's friend and getting him princess kisses to re-ignite his "spark" and keep the flower from wilting - only to get closer to ''it'' rather than him. After some bonding, she grows to love Finn. [[spoiler:(Enough to drink royal jelly and become a Queen Bee to protect him from other bees.)]]

-->Voiced by: Creator/AshlyBurch

* ActionGirl: [[spoiler:Post transformation.]]
* {{Adorkable}}: Seems to share many aspects with Finn, including getting very nervous when in a more emotional situation.
* TheBusCameBack: She eventually makes an appearance in the short "Frog Seasons, Spring (Again)".
* ChuckCunninghamSyndrome: Her one appearance had a HUGE impact, as you can no doubt tell from the spoilers, and she's even [[spoiler: teased as a love interest who can be everything Finn has ever wanted]], but she abruptly disappears and has yet to so much as be referenced ever again.
* {{Foil}}: To Princess Bubblegum. [[spoiler:Breezy, being a queen bee who loves Finn and needs a knight, contrasts PB being eternally a princess with no plans to marry and become a queen, and not returning Finn's affection. Breezy is literally everything Finn ever wanted from PB but cannot receive, and dialing up the irony is the fact that this time, it's Finn who doesn't return the affection. Lampshaded via symbolism when Finn sees her silhouette near the end of her episode, and he mistakes her for Bubblegum for a moment.]]
* InterspeciesRomance: Though it doesn't start off as such, it begins with Breezy simply wanting the flower that came out of Finn's arm stump at the Citadel. Through the episode, the friendship blooms into her feeling affection to Finn, rather than the flower. [[spoiler:Though she is just a bee, she becomes a more humanoid Queen after stealing royal jelly to protect Finn. However after that, Finn still sees her as just a friend and she seemingly leaves. ''After that'', she returns after Finns attempts making out with LSP fail to keep the flower from wilting, and her singing seemingly sparks enough passion to make the flower literally explode into a tree and give Finn's arm back. This seems to spark his interest in her, but only time will tell if this goes anywhere.]]
* JerkWithAHeartOfGold: Only wants to help Finn to keep the flower alive, but grows out it as she spends more time with Finn.
* ThePowerOfLove: [[spoiler:She returns to Finn after she leaves him for saying that he thinks they should just be friends and spends the night with LSP. The two perform a duet which makes the flower blossom until it explodes and returns Finn's arm. Bonus points in Finn that he sees PB during the song and realizes it's Breezy afterward, with an awed expression.]]
* [[spoiler:PsychicPowers: In her Queen Bee form, though it isn't certain whether this only extends to other bees or not.]]
* RebelliousPrincess: To get Finn to continue being responsible for the flower, she eventually tells Finn that she's a Virgin Queen Bee, running from her responsibilities. [[spoiler:She eventually gets over this for Finn's sake.]]
* [[spoiler:ShesGotLegs: In her Queen form, she has a shapely waist and legs after getting her new body. [[JustifiedTrope Justified]] in that, much like real bees she has pollen sacs in her legs (though hers look more like belt pockets.]]
* TransformationSequence: [[spoiler:Goes through a somewhat unsettling one to rescue Finn out of love, becoming a humanoid bee creature. To be specific, she vomits honey which wraps around her, making her grow and form her humanoid appearance.]]
* WalkingSpoiler: Wouldn't expect that out of a simple bee, would you?
* {{Wingman}}: What she becomes to Finn after they first meet.

[[folder:Urgence Evergreen]]

Millions of years ago, Earth was protected by four elemental guardians representing Ice, Flame, Candy and Slime. The strongest in their number was Urgence Evergreen, master of ice. With this power and stature came arrogance and would lead to his undoing in an effort to stop a sinister comet through the creation of a magical wishing crown.

* MeaningfulName: Evergreen trees thrive in cold, northern climates.
* NiceJobBreakingItHero: "Hero" [[GoodIsNotNice is pushing it]], but he does try to use the Ice Crown to stop the end of the world. However his abuse towards Gunther [[spoiler:causes him to fail at stopping the extinction of the dinosaurs, and create an ArtifactOfDoom that causes people to go crazy and could start a new Ice Age if overwhelmed.]] ]]
* RedHerring: The episode of the same name suggests that he might have been [[{{Reincarnation}} reincarnated]] as the Ice King, considering they're both wizards with ice powers, share similar physical appearances, and even have the same voice actor. [[spoiler:The episode "Elemental" reveals that he's not: Ice King is just Gunther's imitation of Evergreen, while his most recent reincarnation has been a HumanPopsicle since before the Mushroom War.]]
* ReplacementGoldfish: [[spoiler:In a sense, people who put on the crown are this, as the crown transforms its wielder into Gunther's crazy, skewed version of Evergreen.]]


A young green dinosaur that Evergreen granted intelligence to serve as his assistant. Despite Evergreen's refusal to teach him magic and continually putting him down, Gunther sees Evergreen like a father and eagerly jumps at the chance to learn magic or join on Evergreen's adventures.

* AnIcePerson: As the Ice Elemental, her powers are equal to or greater than Ice King's as well as more fine-tuned. Note how smooth and clean-looking her ice constructs are.
* ElementalEmbodiment: The reincarnated Ice Elemental from before the war.
* GoneHorriblyRight: She managed to complete her spell to put herself and the elemental princesses in full touch with their power, but the others were overwhelmed by their powers.

[[folder:People of the Islands]]
The Islands are an Archipelago in which Humans live. They were founded by Two Bread Tom and his followers nearly a thousand years before the events of the show.

!!The Islands in General:
* DefectorFromDecadence: The 'Hiders' are people who try to escape the Island.
* FantasticCasteSystem: Seem to have a some sort of caste system, although notably not every member of the Island society seems to be apart of a caste. The three currently known castes are Experimenters[[note]]Most likely the scientists or engineers of the Islands.[[/note]], Seekers[[note]]Seems to be a sort of soldier or guard caste tasked with preventing people from escaping the Islands[[/note]] and Helpers[[note]]They seem to be the doctors and medical professionals of the Islands.[[/note]]
* PoliceState: Their society has a group of elite solders who drag any one attempting to leave off to re-education. [[spoiler:Minerva replaces these with her fleet of robots, which initially seems to be even more controlling, [[ConspiracyRedemption but Finn convinces her to lightening off and allow people to leave]].]]

[[folder:Marceline's Mother]]

First seen in a flashback in "Everything Stays", she was a human woman who gave birth to Marceline right before the Mushroom War.

-->Voiced by: Rebecca Sugar

* AmbiguouslyBrown: She either has a dark tan or may have mixed blood in her family.
* CreatorCameo: Voiced by Rebecca Sugar, an ex-storyboard artist responsible for much of Marceline's development.
* GoodParents: From the little that is seen, she certainly does a good job raising a half-human/half-demon child (presumably by herself mainly).
* InterspeciesRomance: Had one with Hunson Abadeer at some point.
* NoNameGiven: We're never told her name, and we only know that she's Marceline's mother from the conversation she was having with her.
* PosthumousCharacter: Likely dead due to how far off into the future the series is. She only shows up briefly in a flashback.
* TheUnreveal: Beyond her name being unrevealed, just how she got into a relationship with Hudson Abadeer, especially considering this was before the return of magic. In fact, her first words heard was her finishing this story to a young Marceline:
--> '''Marceline's Mother:''' Then he said fine. And that's the story of how I met your dad.

Jo (AKA Bunny Girl) Is a young girl first appearing in the Stakes mini-series in which she befriends a younger Marceline. She later stars in the Adventure Time Islands Graphic Novel.

* NatureHero: Seems to have become one by the end of the Islands Graphic Novel.

* WhatHappenedToTheMouse: So far we haven't learned what happens to her after the Islands Graphic Novel or what her ultimate fate is.


[[folder:Susan Strong]]

A member of an underground dwelling group of humans. The "humans" she lives with are eventually revealed to be ''hyoo-mans'', a strange race of FishPeople living in the ruins of human civilization. Susan herself is the only true human amongst them. She gets a focus arc in season 8 explaining her origins. [[spoiler: Her real name is Kara, and she was an elite member of humanity's "Seeker" caste who was sent to Ooo 16 years ago to find Martin and baby Finn and bring them home, but somehow ended up getting lost herself.]]

-->Voiced by: Jackie Buscarino

%%* DO NOT ADD Amazonian Beauty. This character is simply muscular. She is not portrayed as attractive.
* AmbiguouslyGay: She has an extremely close relationship with Frieda in the season 8 mini-series.
* AmbiguouslyHuman: She is fully human, though she does have some cybernetic implants from her home.
* CowardlyLion: Better than the rest of her people, certainly.
* {{Expy}}[=/=]ShoutOut: Of Tarzan, much like Finn. In Susan's case it's a lot more obvious, since she's RaisedByWolves that ''don't'' act civilized but live as a group which she leads, and she doesn't speak fluent English.
* GreenEyes: Not that they really indicate anything though.
* HugeSchoolgirl: Big in every way. There is pretty much no physical indication of youth, leading to her VagueAge.
** Played straight(er) in the "Islands" flashbacks: [[spoiler:Susan was already ''extremely'' muscular as a young teen thanks to her Seeker training - however this had very little impact on her social life (since this was perfectly normal for Seekers), and actually had a ''positive'' effect on her self-image because she loved being buff.]]
* PhlebotinumRebel: [[spoiler:Susan was trained and cybernetically augmented by Doctor Gross into being her most powerful Seeker, and ultimately plays a key role in defeating her.]]
* RightForTheWrongReasons: [[spoiler:It turns out Strong really is her surname. All humans from the Mysterious Islands are given a designation comprised of a serial number combined with their last name: Finn's is P-G-8-7 "Mertens" and hers is X-J-7-7 "Strong."]]
* SmallRoleBigImpact: Susan was the one who [[spoiler:"introduced" Finn's parents to each other - she broke both of Martin's legs during a Seeker mission and dropped him off at the hospital where Minerva worked.]]
-->'''Minerva''': What've you got for me, [[spoiler:Kara]]?
-->'''Susan''': A sad old hider with two busted legs.
-->'''Minerva''': Oooh, I love busted legs!
* SpellMyNameWithAnS: The hyphenation of her serial number is different in each of its appearances - when first shown on her cranial implant it reads "X-J-7-7", then "XJ-77" when displayed on a computer monitor, and finally as "XJ-7-7" when shown on BMO's face.
* SweetTooth: She, along with the rest of her tribe, actually tries to eat the ''entire Candy Kingdom''.
* TookALevelInBadass: In her second appearance she's the leader of the Hyoo-mans in all but name, conquers some major fears, and is generally a ferocious warrior.
** Zig-zagged - she was actually regaining levels of badassery that she had lost when she lost her memories.
* TheUnreveal: We never find out [[spoiler:if she's a fish person like the others, or a real human.]]
** At the end of 'Beautopia' [[spoiler:after she gently moves Finn's hand beneath her hat, we don't get to see whether or not there's a set of gills there or a human ear. Finn's reaction and Susan's CharacterDevelopment imply that she is human.]]
** Though her eyes did [[spoiler:glow in the dark like the rest of the fish people in 'Beautopia'.]]
** The question finally gets a conclusion that only opens up more questions in "Dark Purple": [[spoiler: she IS a human, but also has a cybernetic implant.]]
*** These questions all get answered during the "Islands" mini-series, but bring up yet ''more'' questions. Namely, it's never explained how Susan lost her memories or ended up living with the Hyoo-mans.
* VagueAge: She and Finn have more than a little chemistry, and HulkSpeak and NaiveNewcomer aside they seem to be on the same intellectual level. However, Susan's body type is very much that of an adult woman. The season 8 mini-series shows that she is at least 15-20 years older then Finn, as [[spoiler:she knew his parents before he was born and was sent to retrieve him when he was an infant]].
* YouNoTakeCandle: When Finn and Jake first find her, she barely knows how to speak until the two heroes teach her and she steps up to this trope. She's getting better at speaking though, as seen in "Beautopia". [[spoiler: When she regains her memories, she speaks perfect English again.]]


A human woman of Swedish decent at a scientific outpost on the Weather Island.

-->Voiced by: Helena Mattsson

* SoleSurvivor: The other people at the base all died from the harsh climate and dangerous giant animals -- [[GoneHorriblyWrong which they caused in the first place.]]
* TheUnintelligible: She only speaks Swedish,, though she does seem to start figuring out what Finn's saying, eventually.


A human "Experimenter" from the Islands.

-->Voiced by: Jasika Nicole

* AmbiguouslyGay: There's significant room to interpret her {{Childhood Friends}}ship with Kara as [[ChildhoodFriendRomance developing into something more]]. [[spoiler:In particular, when Susan/Kara and Frieda ride off, Frieda is hugging Susan's neck from behind.]]
* DarkskinnedRedHead: The one time her hood is removed we see she has long red hair.
* FantasticCasteSystem: She's a member of caste of humans raised to be scientists.
* IJustWantToBeFree: She's one of many humans who wants to leave [[HiddenElfVillage the Islands]], feeling [[GildedCage they can't be free while they live there]]. Despite Kara being tasked with preventing escapes, Frieda gets her reluctant support in making a vehicle to ride out, [[spoiler:but her attempted is crushed at the last second when Dr. Gross finds them and forces Susan to destroy her vehicle.]] Later on, [[spoiler:[[MoreThanMindControl a combination of re-education and being stuck for years]] has convinced her that wanting to leave was a bad idea. Susan and Finn eventually get her to remember what she wanted in the first place, and she becomes the first human to willing move out of the Island.]]


[[folder:Minerva Campbell '''(MAJOR SPOILERS)''']]

Finn's mother, a human "Helper" from the Islands. She met Finn's father Martin after he was injured trying to escape. When Martin ran from attackers with Finn in tow, accidentally landing them both off the island, Minerva was so distraught that she rededicated herself to her work harder than ever. After a deadly virus outbreak leaves her terminally ill, Minerva uploaded herself into the Islands' computer, created an army of robotic version of herself to take care of everyone, and became the de facto ruler of the Islands.

-->Voiced by: Sharon Horgan

* HundredPercentAdorationRating: As a doctor, she was so trusted that people believed what they ''knew'' was complete nonsense just because she said it.
* AntiVillain: Everything she does comes from a genuine desire to keep people happy and safe.
* BigBad: She's the one running the Islands, keeping anyone (especially Finn) from escaping.
* BrainUploading: Dying from a plague, she uploaded her ''entire body'' into a computer network.
* ChronicHeroSyndrome: Her son got his natural urge to help people from her. She even went as far as to upload herself into a computer so she could keep taking care of everyone in Islands after her body died during a plague.
* ExhaustedEyeBags: Her tireless work as a doctor shows in the slight bags under her eyes.
* FantasticCasteSystem: She's born in the "Helper" cast, which consists of doctors and aid workers, and is very much into the role. Despite this, she seems to have eliminated the system herself, as the robots replace the visible function of Seekers and Helpers (the latter all having died) while Frieda has gone from an Experimenter to working at a toy shop.
* FlorenceNightingaleEffect: She met Martin when he was in the hospital for two broken legs and she was his nurse. They started dating after she took pity on him and saved him from being taken to re-education.
* {{Foil}}:
** To Finn. They enjoy their work in helping others who are in need, which both can do in extreme methods. Finn takes his method of physical helping violently so long as evil is the only one trampled across his path, Minerva helps people exceptionally but peered close enough to doom her people nearly twice in her choices.
** To Princess Bubblegum. They both shown their work to Finn on how they operate their respective colonies scientifically. Bubblegum is able to let go of her totalitarian approach with Marceline's help, while Minerva is still plagued by the thought of her husband abandoning her along with her own child only for said child help her in getting a hold of herself.
** To Martin. Martin was a self serving sociopath who only ever [[ItsAllAboutMe cared about himself]], while Minerva is empathetic to the point that she made her entire existence about helping others. Neither of them are shown to be well adjusted individuals though for very different reasons.
* FollowInMyFootsteps: She finally see her son as something other than [[MyBelovedSmother a child to be kept safe]] when she finds out Finn grew up to be a "helper" like her.
* GenerationXerox: Her character design is not only as similar as Finn's, they are just as helpful to the people around them, [[{{Foil}} just in different methods]].
* HairOfGoldHeartOfGold: Just like her son, Minerva has blonde hair and is a good-hearted person who wants to do nothing more than help people. It's true her methods can be pretty extreme, but Minerva ultimately means well.
* HeelFaceTurn: After seeing Finn's desire and acts to help people despite growing up in Ooo, she decides maybe the outside isn't so terrible and that people should be able to leave if they want.
* HorribleJudgeOfCharacter: She fell for Martin even though she knew he was manipulative and even explained how he'd take advantage of her before doing so. It's highly ambiguous whether [[LoveRedeems she made him a better person]] (at least temporarily) or was [[TheFarmerAndTheViper just a naive do-gooder exploited by a con man]].
* KnightTemplarParent: She attempts to [[UnwillingRoboticisation force her son into]] ''[[BrainUploading uploading his consciousness to the internet]]'' for his safety. Her EstablishingCharacterMoment even shows shades of MyBelovedSmother.
-->'''Miverva''': But that doesn't matter anymore! You can stay here, with me!\\
'''Finn''': Oh, I don't think that's necess-- (''Miverva-Bot clutches onto Finn'')\\
'''Miverva''': ''For the rest of your life.''
* LastOfHerKind: Unless you count Finn, she's the last Helper after the rest were killed treating a plague. [[BrainUploading If you consider her to be alive.]]
* LikeParentLikeChild: Minerva and Finn both [[ChronicHeroSyndrome dedicate their lives to helping people]], though Minerva takes this [[TotalitarianUtilitarian much further]].
* LikeParentUnlikeChild: Despite having the same core goal, her and her son's methods are complete opposite: Finn tries to protect people by fighting evil, sometimes to the point of being excessively violent. Minerva tries to take care of people to the point of coddling them.
* LogicalLatecomer: She's lived in a HiddenElfVillage all her life, and considers what Finn shows her of the rest of Ooo not just dangerous but also bizarre.
-->'''Minerva:''' Your world seems so chaotic. Your ruler is a piece of gum, your friend's a vampire, you dated a bit of fire--Your life is constantly in danger!
* MeaningfulName: Shares her name with the Roman goddess of wisdom and medicine.
* MissingMom: She was separated from Finn when he was a baby and he never got to meet her until their encounter in ''Islands''.
* MyBelovedSmother: When she finds out Finn is alive and came to the Island, she insists he can't leave, even though he has a whole life outside.
* NiceGirl: She's overprotective, but other than that's she's a helpful and well-intentioned person.
* NotEvenBotheringWithTheAccent: Her voice actor uses her natural Irish accent, which no one else on the Islands has.
* OppositesAttract: A tireless, trusting, over-protective doctor who fell in love with a lazy, two-siding, self-serving conman.
* ProHumanTranshuman: She [[BrainUploading converted herself to a digital lifeform]] to keep helping people even after her body gave out.
* SanitySlippage: It's clear that losing Finn took a heavy toll on her psyche and dealing with a lethal virus that wiped out all of the helpers pretty much finished the job that started. All of her actions in the present are very realistically shown as not sane ones.
* TotalitarianUtilitarian: She makes sure everyone on the Island is happy and safe, never letting them experience anything else in life. When many people show signs of wishing to leave, she tries to [[UnwillingRoboticisation forcibly]] [[BrainUploading upload them into the computer]] so they can never leave.
* WalkingSpoiler: The fact Finn's mother is alive one of the first major twists of ''Islands''. That she's the BigBad of the arc is another.
* WellIntentionedExtremist: [[KnightTemplarParent Her treatment of Finn aside]], she also tries to keep the residents of the Islands safe by ensuring they never leave, [[DeconstructedTrope but in doing so, she's crippled them developmentally and they have a difficult time making their own decisions]] and when she notices that they start to consider to leave the Islands, she tries to [[UnwillingRoboticisation forcibly]] [[BrainUploading upload them into the computer]].


!!Deities and Cosmic Beings

An all-powerful being who resides in the center of the multiverse. He's close friends with the Cosmic Owl, and has the power to grant wishes (with a twist) to anyone who reaches him, and alter the course of time itself at will. [[spoiler:He is the product of an old man's dream, who keeps Prismo alive as long as he's asleep. However, the Lich kills his corporeal body in "Wake Up," ultimately killing Prismo as well. This did not stop him for long as he used a time paradox to return.]]

-->Voiced by: Kumail Nanjiani


* {{Adorkable}}: He's an extremely awkward, exceedingly nice guy.
* AlwaysSomeoneBetter: Despite being a very powerful entity, ''Crossover'' reveals that he does have someone he needs to answer to if something major (like the Space-Time Continnum being destroyed) happens. Considering what Prismo can already do and given what it might take to piss Prismo's boss off, that says a frightening amount of how powerful they must be.
--> '''Prismo:''' Now if that happens, my boss, ''let me repeat that, '''[[PunctuatedForEmphasis My. Boss.]]''' will hold '''me''' responsible.'' And by proxy, ya'll both will be in the dip too.
* AmbiguouslyGay: Prismo's pink-colored, he talks with a slight lisp, and he tends to chill in a hot tub with his guy-friends Jake and the Cosmic Owl. One topic of discussion in his room is him finding a girlfriend, which he awkwardly hems and haws over.
* BackFromTheDead: [[spoiler:He came up with a plan to bring himself back should he ever die, involving Finn and Jake. After Jake eats the last pickle Prismo made, he's sent to a weird place that seems to be outside time. A time double of Jake becomes the new dream host for Prismo.]]
* BadassAdorable: He's unbelievably sweet, but he can alter reality and grant a potentially infinite number of wishes of any kind to ''anybody.''
* BecauseYouWereNiceToMe: A variant in that he admitted that part of the reason he helped Jake was that he greatly appreciated Jake actively being friendly to him as his only other friend seems to be the Cosmic Owl.
** This extends to Finn as he was willing to risk himself to help Finn meet his dad.
* BenevolentGenie: He's nice to an almost absurd degree. How nice? He straight out tells Jake not to waste his one wish on something stupid, [[CallBack like a sandwich]], as well as explaining the fact that despite all of Prismo's power, he's still bound to giving wishes that have an "[[BeCarefulWhatYouWishFor ironic twist]]". Heck, he even ''very heavily'' hints at the ''proper'' wish Jake ''should'' make to fix the whole mess made with Finn's wish.
* CelestialBureaucracy: "Crossover" reveals that he does have a boss that is implied to be much more powerful than him. He does mention that should the Space Time Continuum be destroyed, this boss would hold Prismo responsible (and apparently his associates/friends as well, considering Prismo tells Finn and Jake that by extension, they'd be in trouble too.)
* CheatedAngle: He's almost always in profile but that seems to be by choice. He can turn his head despite his one-dimensional appearance.
* ConfirmedBachelor: He tells Jake that he prefers the single life because relationships require too many compromises, using the question of coordinating dinner plans as an example. Jake disagrees and says that he needs to find Prismo a girlfriend, although [[HoYay Prismo seems more interested in Jake's company than anyone else's]].
* CouldSayItBut: He stretches this trope about as far as it goes.
* TheCutie: ''GOOD LORD.''
* DidntThinkThisThrough: [[spoiler:He tried to help Finn with meeting his father by having the heroes bring his mortal body into the chamber, with the Lich in the room the entire time.]]
* DreamApocalypse: [[spoiler:The wish-granting genie is really the dream of the real and relatively normal man. Waking him up destroys the Wishmaster form, a crime worthy of the ''{{C|rystalPrison}}itadel''.]]
* FatalFlaw: [[spoiler:A bit of a different version as his flaw isn't necessarily "bad": arguably, he's too nice and trusting to people, possibly caused from his isolation from society and desire for friends. Allowing himself to temporarily die (and later permanently die) for someone he's only known for a little while exemplifies this.]]
* LiteralGenie: Played with. The wishes executed act like this in nature, but he admits that he doesn't do it deliberately because it is out of his control. Careful, specific wording can get around the BeCarefulWhatYouWishFor part, and although he granted [[OmnicidalManiac The Lich's]] wish as it was, he's nice enough to help Jake to wish for the right thing and screw The Lich over.
* LivingDream: [[spoiler:He is an entity born from the dreams of an elderly man.]]
* LivingShadow: He basically looks like a moving picture of a person on the floor and ceiling.
* NiceGuy: Really nice. He seems like an all around great guy.
* OhCrap: [[spoiler:When the Lich is about to wake him up instead. It makes a certain amount of sense. The Wishmaster form would simply be incapacitated until his mortal form goes back to sleep in a thousand years, whereas if the Lich kills him, he's kinda screwed.]]
** [[spoiler:He does another one along with the Cosmic Owl when Betty says that she's going to rewrite history to prevent the Mushroom War from happening.]]
* OurGeniesAreDifferent: He grants wishes like genies would, but he's two-dimensional, is physically like a shadow and he lives at the center of the multiverse.
* RealityWarper: He grants wishes that can alter the course of history.
* SenselessSacrifice: [[spoiler:He allows Finn and Jake to wake up his human form, thus destroying his Wishmaster form. He did that so Finn could be sent to the Citadel to meet his human father... who was a manipulative {{Jerkass}} extraordinaire, and had no interest on Finn at all.]]
* TimeMaster: Sort of. He uses wishes to allow people to navigate TheMultiverse and stays in [[NarniaTime his own time-sealed room]], but doesn't really ever leave it.
** His [[spoiler: revival involved the use of a special room with a bizarre flow of time. Beyond creating a temporal duplicate of Jake to serve as Prismo's new 'host', Finn's time double becomes the Finn Sword.]]

[[folder:The Cosmic Owl]]
A mysterious and important entity in the land of Ooo, it appears to others in visions. It speaks in a Southern drawl [[TheOtherDarrin initially]] and is a friend of Prismo.

-->Voiced by: Jeremy Shada (What is Life), M. Emmet Walsh (all other appearances)

* AnimalisticAbomination: A golden energy owl that appears in others consciousnesses and according to the Why-Wolves capable of devouring entire populations if they prove too numerous.
* CosmicEntity: The exact details of his powers aren't clear, but the people of Ooo regard him as a being of great importance.
* DreamWalker: By entering people's dreams, he ensures that they come true, either literally or metaphorically.
* EnergyBeing: It is an owl that is made out of yellowish cosmic energy.
* NiceJobBreakingItHero: [[spoiler: In Hoots, he accidentally is present while Princess Bubblegum was dreaming about the Candy Kingdom's destruction, meaning he accidentally doomed the kingdom to an unknown catastrophe.]]
* OhCrap: [[spoiler:He does one along with Prismo when Betty says that she's going to rewrite history to prevent the Mushroom War from happening.]]
* OminousOwl: Subverted; it's less of a malevolent force and is [[BlueAndOrangeMorality more of a natural force]] with some hobbies.
* OnlyFriend: Prismo is his.
* PhysicalGod: Easily one of the most powerful entities in the series, but it does not directly interfere in the plot.
* RealityWarper: To a certain extent. The way his powers work mean that, whatever the person is dreaming, as long as he is present, it ''will'' come true in the real world.
* VerbalTic: He hoots whenever he says a word with an "oo" sound.
* VocalDissonance: One of the most ancient and powerful entities of the series, but it has a youthful, Southern drawl.

[[folder:Abraham Lincoln]]

The King of Mars, and possibly the most powerful being in the ''Adventure Time'' universe, with the exception of Prismo.

-->Voiced by: Pendleton Ward

* BalancingDeathsBooks: [[spoiler:He accidentally executed Jake thinking he was the Magic Man. He travels to the Eighth Dead World to bring him back, where he meets with Death. When Death refuses the payment of one penny, the King offers his immortality instead, killing him and turning him to stone (an exact replica of the Lincoln Memorial, in fact).]]
* EarlyBirdCameo: Lincoln appeared as early as the ''2008 short'' in a very... [[BigLippedAlligatorMoment weird scene]], and never came back until "Son of Mars" in 2012!
* FriendlessBackground: As revealed in "Sons of Mars":
-->'''Lincoln''': "My judgement was less than the standard by which I judge my peers... of which I have none."
* GodEmperor: He's the Martian King. He also appears to be a god.
* HeroicSacrifice: [[spoiler:In order to bring Jake back from the dead, he offers Death his own immortality.]]
* LargeHam: He can be ridiculously hammy.
* MyGodWhatHaveIDone: Upon [[spoiler:Jake's death, who he thought was the Magic Man]].
* NoIndoorVoice: Well, he's never really indoors.
* NonstandardCharacterDesign: Really the only character in the entire series drawn with vaguely realistic features.
* TheParagon: Finn refers to him as "the wisest, most honest superbeing of all time".

[[folder:Grob Gob Glob Grod]]

A four-faced deity from Mars, and Magic Man's older brother.

-->Voiced by: Melissa Villasenor (Grob), Creator/TomKenny (Gob), Tom Gammill (Glob), Miguel Ferrer (Grod)

* CainAndAbel: The Abel to Magic Man's Cain.
* CosmicEntity: But like the Cosmic Owl, the extent of his power isn't clear.
* FlamingSword: His weapon of choice, which he used to defeat Orgalog.
* GodIsDead: As of "Astral Plane." [[spoiler:Subverted in "Normal Man" where it's revealed they're not dead, but have become orbiting entities around Earth/Ooo.]]
* GuardianEntity: Was the guardian of Mars and, to a lesser extent, the rest of the solar system.
* HeroicSacrifice: [[spoiler:Seemingly dies protecting the people of Mars from an incoming 'catalyst comet', which turns out to be Martin's spaceship]]
* MultipleHeadCase: He has four faces, each of which is a distinct being.
* PhysicalGod: A literal god/cosmic being who physically fights to protect the worlds, and capable of striking down an EldritchAbomination.
* PiecesOfGod: His helmet fell down in ''You Forgot Your Floaties''. [[spoiler: Magic Man tried to use it and Betty's true human blood to take his power, but Betty took it instead. And Magic Man's. Also, his 4 heads now orbit the earth. He's still alive and sentient, but has chosen not to intervene anymore.]]
* StarfishAlien: Even by ''Adventure Time'' standards, he's one of the strangest-looking beings in the show.

Ruler of the Land of the Dead, and has power over the deceased, able to raise them whenever he wills it. Best friends with Peppermint Butler.

-->Voiced by: Miguel Ferrer

* DealWithTheDevil: In "Sons of Mars", Death agrees to resurrect [[spoiler:Jake]] in exchange for [[spoiler:Abraham Lincoln's immortality.]] It's also implied that he once revived someone for Lincoln in exchange for a ''penny''.
* DemBones: He appears as an anthropomorphic skeletal equine.
* DontFearTheReaper: When we actually see him doing his job as opposed to dealing with people invading his territory and trying to resurrect people, Death is rather friendly. He prepares a special trip for [[spoiler:Simon]] with music and everything and both he and his target consider it a MercyKill. When said target decides to let the attempt to save him go on anyways, Death steps back to see what happens.
* {{Intangibility}}: Apparently you can't kick him if your brain is stupid. More seriously, WordOfGod states that even ''the Lich'' hasn't ''beaten'' him, merely ''cheated'' him.
* KissOfDeath: Subverted. A kiss from Death gives you your memory back.
* LightEmUp: Lives in a castle of light. [[LightIsNotGood This doesn't affect his morality much]].
* ManInWhite: Is decked out in all white clothing.
* NiceHat: Rocks a cowboy hat.
* NiceGuy: When not angered, he's a pretty nice guy surprisingly. This is particularly true with his girlfriend, Life, who he tries his best to get a birthday present for.
* RockMeAsmodeus: For a skeleton, he's quite skilled with a guitar.
* SeriousBusiness: Musical battles.
-->'''Death:''' Those the rules of the Land of the Dead; lose a music battle, lose your life.
* StealthPun: Plays DeathMetal in a musical battle.

The personification of life. Death's girlfriend. Appears in the digital short "The Gift That Reaps Giving".

-->Voiced by: Creator/HyndenWalch

* FertileFeet: Plants grow wherever she walks. When she kisses Death's cheek, flowers grow, which naturally wilt instantly.
* MultipleHeadcase: Has two heads.
* SnakePeople: She has two intertwined snake heads, referencing the [[https://en.wikipedia.org/wiki/Caduceus caduceus]].
* VoiceOfTheLegion: Her heads speak simultaneously, creating this effect.

[[folder:The Catalyst Comet]]
The otherworldly force that causes major, and often dangerous, changes in the world whenever it passes. [[spoiler: In "The Comet", it is revealed to be sentient and actually rather benevolent.]]

-->Voiced by: Creator/TigNotaro

* AlienGeometry: It's really [[spoiler: a hollowed-out sphere with 3 eyes.]]
* ArcVillain: Sorta one for season 6. [[spoiler: Subverted when it's revealed to not really be evil.]]
* AscendedToAHigherPlaneOfExistence: Its offer to Finn, which he declines. [[spoiler: Martin is eager to take it up, though.]]
* CometOfDoom: Causes catastrophic events whenever it passes. [[spoiler: It turns out that it isn't a malevolent force, but rather just an agent of change.]]
* LongList: [[spoiler: Tells Finn about the attributes and events in his life while bringing up its cosmic offer, and when Finn points out that it's just droning on, the comet defensively states that it's a long list.]]
* PurpleIsPowerful: It can alter the course of reality itself!
* WalkingSpoiler: [[spoiler:Due to its sentience and intentions.]]

[[folder:The Multiverse]]

The sentient totality of all universes across existence.

* AllThereInTheManual: It is only briefly alluded as sentient during the series itself by Finn, who "prays" to it during the events of The Comet, but its nature and mechanics are only explained by the spin-off book "The Enchiridion"
* DreamLand: "The Sleepers" are capable of dreaming entire universes into existence. [[spoiler:The Enchiridion itself implies The Multiverse is just a dream of a mysterious entity known as "The Reader".]]
* GodsNeedPrayerBadly: Well, perception in this case. Basically, The Multiverse is a reality formed by the collective consciousness of all living things in existence, and if there is no one left to observe it, it simply ceases to exist. [[spoiler:Somewhat Averted, as The Enchiridion states The Multiverse can potentially return to existence, in some "new, unknown way", even after ceasing to be in its entirety.]]
-->''The Multiverse is a Consensus Reality shared by the Minds of all Sentient Beings. If they were to Die, the Multiverse, as such, would suddenly blink out of existence, vanish, be no more."
* OurGodsAreDifferent: It is literally an infinite, self-aware and self-born collection of universe and dimensions.
* PowerSource: It is the source of all Magic across all of existence, as Mages can use their minds to alter reality by tapping into The Multiverse's powers, achieving the capability of using Magic.
* SentientCosmicForce: A sentient multiverse.
* TheMultiverse: It's ExactlyWhatItSaysOnTheTin.

!!Other Inhabitants of Outer Space and Alternate Dimensions
An odd figure from the future, and narrator of stories he calls Graybles.

-->Voiced by: Creator/EmoPhillips

* GreekChorus: Acts as one for his Graybles.
* TheLegendOfChekhov: His Graybles appear to be thematically-tied short stories, [[spoiler:then we later learn that they're true accounts from 1,000+ years earlier.]]
* NoFourthWall: He routinely speaks directly to the viewers.
* SuddenlyFluentInGibberish: Peppers his sentences with nonsensical words. For example.
-->'''Cuber:''' I'll see you crimpy glimmers on triode flimpin' the diode.
* TricksterMentor: Sorta acts like this to the viewers because some of his Graybles are designed to mislead the audience.

[[folder:Farmworld Finn/Ice Finn]]
Finn's counterpart in the "Farmworld" universe created from a wish made to attempt to stop the Lich.

-->Voiced by: Jeremy Shada

* AlternateSelf: Of Finn the Human. Duh.
* AntiVillain: He becomes the new Ice King and starts freezing everyone on Earth [[ObliviouslyEvil because he thinks that's protecting them]].
* AnIcePerson: He puts on the Ice King's crown and uses its power.
* ArtificialLimbs: Has a crude mechanical right arm.
* ClassicalAntiHero: Compared to main world Finn, he's a lot less respected, and his initial goals are mostly on protecting his family.
* TheBusCameBack: [[spoiler:"Cross Over" reveals that the Farmwold was not erased by Jake's wish, it continued to exist in parallel with other realities. Our Finn, with Prismo's help, travels to the alternate timeline and exorcises both the Lich and the ice crown.]]
* DoesNotLikeShoes: Never seen wearing shoes. Possibly also an example of BarefootPoverty.
* {{Gonk}}:
-->'''Jake:''' Man, Alternate Wish-World Finn is mad uglies!
* TheNoseless: {{Inverted|Trope}}. His most significant feature from the regular Finn is that Finn's nose, like most of Ooo's, isn't visible.
* UnwittingPawn: [[spoiler:The Lich of his world tricks him into a plan to destroy every timeline, which Ice Finn falls for because he's too insane to see how ObviouslyEvil he is.]]
* WithGreatPowerComesGreatInsanity: Ice King's crown drives him very crazy, very fast.

[[folder:The Shape-shifter/Warren Ampersand]]
A strange monster that Joshua and Margaret encounter during one of their investigations. Has only appeared in "Joshua and Margaret Investigates" so far [[spoiler:until his return in "The First Investigation" and "Jake the Starchild"]].

-->Voiced by: Creator/JohnDiMaggio, Dave Foley ("The First Investigation" and "Jake the Starchild")

* AbusiveParents: [[spoiler:Manages to be even worse than Martin and Hunson combined.]]
* AffablyEvil: [[spoiler:He’s rather friendly and personable... for a guy who only reproduces so that he can drain his offspring’s lives later on]].
* AliensAreBastards: Threatens a pregnant lady, [[spoiler:implants its egg into her husband]], and chuckles wickedly at the end of it all before going home... it's the embodiment of this trope, albeit one (somewhat) toned down. [[spoiler:And then there's the reveal about what he did to his own children.]]
* AlienBlood: It bleeds bright green blood after Margaret pricks it with a pin.
* AscendedToAHigherPlaneOfExistence: Played with. He accepts his [[spoiler: impending doom via black hole]] on the grounds that it will lead to this, but it's not clear if that's what will actually happen.
* DisappearedDad / MissingMom: Assuming gender even applies, it's one of these to its child [[spoiler:Jake the dog. Jake isn't even aware that he isn't Margaret's biological child since his parents never told him about their encounter with the Shape-shifter.]]
** [[spoiler:Reveals himself to be male in "Jake the Starchild."]]
* EldritchAbomination[=/=]StarfishAliens: Which one is unclear because we can't quite tell if its origins are extraterrestrial or extra-dimensional. Regardless, assuming [[http://adventuretime.wikia.com/wiki/File:S6e16_Shape-shifter_special_face.png the last form it takes]] in the episode is its true form, it's one of the most bizarre beings in the series.
* FaceDeathWithDignity: When it becomes clear he's going to [[spoiler: get sucked into a black hole]], he swiftly becomes eager to, noting that he has done as much as he can with a physical body, and is interested by the idea of a greater, more cosmic existence - which he thinks the [[spoiler: black hole]] can provide. Then he lets himself die without resistance.
* FaceFullOfAlienWingWong: Inflicted this on [[spoiler:Joshua, with Jake being the result.]][[spoiler: That and several other individuals.]]
* KilledOffForReal: [[spoiler:Jake throws him inside a black hole after he decides to suck the life force of Jake's kids]].
* OffingTheOffspring: [[spoiler:By sucking their life force.]]
* OutGambitted: [[spoiler: Once Jake realizes that Warren is tricking him, he swiftly gets the upper hand over the alien with a simple trick.]]
* PetTheDog: Admits he actually feels something for Jake, and, post-reveal, uses his stretchy powers to try to entertain and comfort him.
* SuperpowerfulGenetics: Passed on its powers and some of its physical traits to its [[spoiler:son Jake and his children.]]
* SuspiciouslySimilarSubstitute: Holds a number of striking similarities to Martin, including being a DisappearedDad, being profoundly selfish but still having a PetTheDog moment related to his kid, being heavily associated with outer space, being skilled at deception, and eventually [[spoiler: choosing to leave behind their prior life to experience a more cosmic existence]].
* VampiricDraining: [[spoiler:Drained the life out of his offspring in order to keep himself alive through a special belt.]]
* VocalDissonance: When we finally hear it speak it has a high pitched nerdy sounding voice despite its size and alien appearance.
* VoluntaryShapeshifter: Turns into many different forms in the only episode it appeared in so far, such as a baby, humanoids, a cat, an owl and many other unknown forms. [[spoiler:He can also create an entire city and actual people on an abandoned planet.]]
* WalkingSpoiler: [[spoiler:He's Jake's parent, and wants to drain his life essence like he has done with his other offspring.]]
* WoundedGazelleGambit: Took on the form of a baby when Margaret had it cornered. Margaret (apologetically) punched it out anyway.

[[folder:Space Moth]]
A gigantic... well, moth that provided milk for the koala people before Martin hijacked it.

* AscendedToAHigherPlaneOfExistence: [[spoiler:Alongside Martin in "The Comet".]]
