    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 Fish People living in the ruins of human civilization. Susan herself is implied to be the only true human amongst them.

Voiced by: Jackie Buscarino

  • Ambiguously Human: She probably is.
  • Badass: That muscular build isn't just for looks.
  • Cowardly Lion: Better than the rest of her people, certainly.
  • Expy/Shout-Out: Of Tarzan, much like Finn. In Susan's case it's a lot more obvious, since she's Raised by Wolves that don't act civilized but live as a group which she leads, and she doesn't speak fluent English.
  • Green Eyes: Not that they really indicate anything though.
  • Huge Schoolgirl: Big in every way. There is pretty much no physical indication of youth, leading to her Vague Age.
  • Sweet Tooth: She, along with the rest of her tribe, actually tries to eat the entire Candy Kingdom.
  • Took a Level in Badass: 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.
  • The Unreveal: We never find out if she's a fish person like the others, or a real human.
    • At the end of 'Beautopia' 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 Character Development imply that she is human.
    • Though her eyes did glow in the dark like the rest of the fish people in 'Beautopia'.
  • Vague Age: She and Finn have more than a little chemistry, and Hulk Speak and Naïve Newcomer aside they seem to be on the same intellectual level. However, Susan's body type is very much that of an adult woman.
  • You No Take Candle: 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".

    The Snail 
A snail who can be seen waving at the audience in every episode. His only notable role in any episode was being mind-controlled by the Lich into releasing it. After spending most of the series being possessed by The Lich, he was finally released when The Lich chose to Body Surf into Billy.

Voiced by: Pendleton Ward

A tiny cat-like assassin.

Voiced by: Kyla Rae Kowalewski

Marceline's old "Genius Wizard" boyfriend. They started living together in the Tree Fort (before Joshua) until Ash moved Marceline away from the Candy Kingdom to his current house. Then he sold her teddy bear to a witch, earning his girlfriend's anger.

Voiced by Steve Agee

  • Affectionate Nickname: He calls Marceline "Mar-mar".
  • Cute Little Fangs: They're a bit more rounded than most examples, though.
  • Does Not Like Shoes: Goes barefoot.
  • Domestic Abuser: Of the emotional variety. He treats Marcie more like an object that should be his rather then a person.
  • Eye Scream: Goes blind while he is beat up as he says "Ohh...I can't see...".
  • Fantastic Racism: He hates Marceline hanging out with "mere mortals".
  • Giant Foot of Stomping: Is the victim of one, eventually.
  • Groin Attack: Also gets one of these.
  • Hoist by His Own Petard: The memory spell he used to try to trick Finn and Jake into retrieving the bad memory of him within Marcie's mind is used by Finn to show her why she dumped him in the first place. What's more the "mere mortals" he tricked join in on beating the crap out of him with Marceline.
  • Jerkass: Is he ever.
  • Kick the Son of a Bitch: In Betty Simon lays him out with one hit and steals his flying carpet. What makes it funny is that Ash pretty much got knocked out by Marcie's surrogate father.
  • Lack of Empathy: Doesn't care about how his actions hurt Marceline, despite it being blatantly obvious they do.
  • Large Ham: Just listen to him describing the sandwich he wants.
  • Manipulative Bastard: Tricks Finn and Jake into going into Marcie's mind and getting the bad memory of him just to claim Marcie as his own.
  • Magical Incantation: His flight spell.
    "Ashicus Flyicus"
  • Never My Fault: Never thinks that Marceline breaking up with him might have been his fault for selling her most prized possession.
  • No-Holds-Barred Beatdown: Gets one at the end of his episode and it was richly deserved.
  • Small Name, Big Ego: If the whole "You're not a Genius" bit is anything to go by.
  • Stay in the Kitchen: His demanding that Marceline make him a sandwich is what finally pushes her to retaliate against him.
  • Straw Misogynist: Darn near parody levels of this. See directly above.

    The Lemongrab Earldom 

Lemongrab 2

Lemongrab's clone. Created by Princess Bubblegum for the purpose of giving Lemongrab a companion.

Voiced by: Justin Roiland

  • Butt Monkey: Not initially, but by "Too Old", he had become this to the original Lemongrab.
  • Clones Are People Too
  • Cloning Blues: Lemongrab 2 was created to be a companion to the first one, and, despite their obnoxious personalities, are actually both very happy together with their family until "Too Old".
  • Color-Coded Characters: To differentiate between him and Lemongrab, one wears grey and the other wears white.
  • Defector from Decadence: Lemongrab 2 in "Too Old" is rebelling against Lemongrab 1.
  • Divergent Character Evolution: 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 levels in cruelty and insanity.
  • Good Parents: As evidenced in "All Your Fault" (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", and especially Too Old, Lemongrab 2 is a loving father to his many children, starkly contrasting the direction Lemongrab 1 wound up going. This is most clearly (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.
  • Hair-Trigger Temper: Though downplayed compared to his clone. In "Too Old" it's nearly nonexistent, presumably because he's very, very weak from hunger and from being sick.
  • Handicapped Badass: 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.
  • Jerkass/Jerk with a Heart of Gold: In his earliest appearances, he comes across as being mildly annoying, but unlike the originalLemongrab, that's the only problem he appears to have. The "jerk" part seems nonexistent by the time of "Too Old", as he's nothing but nice and generous throughout the entire episode.
  • Killed Off for Real: 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.
  • Morality Pet: Formally to Lemongrab. Grossly averted in "Too Old."
  • Naked on Arrival: The first time we see Lemongrab 2, he's butt naked.
  • Only Sane Lemon: 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.
  • Papa Wolf: To the bitter end.
  • Took a Level in Kindness: 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.
  • Vocal Evolution: 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 Only Sane Lemon and selfless Papa Wolf.


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. 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: Justin Roiland

  • Ambiguous Disorder: 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 cardiac arrest, which was only resolved when Finn and Jake punched his heart.
  • Big Damn Heroes: Literally.
  • Children Are Innocent: Oh yeah.
  • Cloud Cuckoolander: Not to the same extent as the earls, but he is a pretty strange dude.
  • Dark Is Not Evil: His appearance is disturbing and he's pretty damn ugly, but he's a downright wonderful guy.
  • Final Speech: Gives a beautiful, eloquent, and heartbreaking one just before 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! The greater good demands but one course only! That I dissolve the bonds uniting me and become component to all!
  • First Time Feeling: "Is this the rumored ache of feeling? The feeling of caring unknown to lemons?"
  • Funny Afro: 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.
  • Gag Nose: He has two. Why the Lemongrabs thought it was essential that Lemonjon have two noses has not been explained.
  • Gentle Giant: Absolutely. He's one of the largest Candy People ever to exist, and he's also perhaps the most selfless.
  • The Giant: He's as big as the whole castle, and is the castle, kind of.
  • Giant Mook: The Lemongrabs attempted to use him as this.
  • Gonk
  • Heart Trauma: Finn and Jake punch his heart to attempt to kill him. Instead, this causes his heart to start beating, resulting in Lemonjon having an epiphany.
  • Heel-Face Turn: While he was never a villain, he seemed neutral, yet still willing to attack the Candy Kingdom. But he eventually Took a Third Option which resulted in his own death.
  • Heroic Sacrifice: To save his family and the Candy People.
  • Killed Off for Real: The second important character to suffer the fate of permanent death- the first was Billy.
  • Large Ham: " Mmmmmm... MENAGERIE! "
  • Like Father, Like Son: "Three weeks dungeon." He seems to have inherited the pedantic speech of his fathers.
  • Literal Change of Heart: His heart actually awakens when Finn and Jake punch it.
  • Moral Dilemma: "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 but his own.
  • The Needs of the Many: His reasoning for his Heroic Sacrifice.
  • No Indoor Voice: 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.
  • Take a Third Option: He 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.
  • Too Good for This Sinful Earth: "Man... That Lemonjon was all right."
  • Tortured Monster: Although the Lemongrabs view him as a child, they did attempt to use him as a weapon. And when he's slowly standing up, after months of literally being attached to the ground, he sounds like he's in pain.
  • Wacky Parent, Serious Child: He seems much more down-to-earth and reasonable than his dads.
  • What Is This Feeling?: Mentions this trope in his final speech.
  • Younger Than He Looks: He's a giant and he has a low, booming voice. But the Lemongrabs say that Lemonjon is "young," and only a child. Which makes his untimely and sudden death all the more heartbreaking.

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 little pooters.

Voiced by: Justin Roiland

  • Affectionate Nickname: According to the screenshot of Lemongrab’s brain, the earls affectionately call their babies “little pooters.”
  • Amazing Technicolor Wildlife: The Lemon Children are a strange combination of person, plant, animal, and fungi- and they’re all various shades of yellow, orange, and green.
  • Ambiguous Disorder: They all seem pretty “off,” but it hasn’t been made clear if they’re as bonkers as their dads yet.
  • Babies Make Everything Better: According to the Lemongrabs.
  • Baby Talk: The only word we could hear them say was “hungry” and "candy." For the most part, they just babble and shriek.
  • Big Screwed-Up Family: Oh, yeah.
  • Body Horror: Some of the Lemon Children are rather grotesque- limbless, disfigured faces, lumpy and misshapen.
  • Carnivore Confusion: 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.
  • Children Are Innocent: Toyed with. They seem to mostly be toddlers, but they’re enthusiastic about their dads’ plan to take over the Candy Kingdom.
  • Cloud Cuckoolander: Obviously, given who their progenitors are.
  • Conjoined Twins: Some of them.
  • Creepy Child: Finn and Jake seem to think this about some of the Lemon Children, especially the one whose face pealed back.
  • Cute but Cacophonic: Many of the Lemon Children are rather adorable in appearance, but they have high-pitched, shrieking voices.
  • Dysfunctional Family: Let's just say, they're about as functional as the Griffins if they were all three times as insane, and lemons.
  • Eyeless Face: Some of them don't have eyes or faces. In fact, some of them are just lemons with wings attached.
  • Gag Nose: 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.
  • Green Eyes: The Lemon Child with the pealing face has green eyes.
  • Grotesque Gallery: They're all twisted and lumpy.
  • Has Two Daddies: They are Lemongrab and Lemongrab 2's children, weird considering they're brothers), but regardless, they're a big happy family.
  • It Runs in the Family: Some of them seem pretty “special.”
  • Last Minute Baby Naming: 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.”
  • Let's Have Another Baby: The earls probably said this to each other at some point, and it just kept happening, over and over again…
  • Like Father, Like Son: Many of them have the same eyes as their fathers, and many of them resemble lemons in some way.
  • Massive Numbered Siblings: Well... there are over twenty of them.
  • Nice Shoes: The multi-mouthed lemon child has a pair of little hot pink cowboy boots.
  • Nipple and Dimed: Several of the Lemon Children have nipples and visible breasts (due to being chubby babies.)
  • No Indoor Voice: 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.
  • One-Gender Race: According to the Lemongrabs, all of their children are male.
  • Petting Zoo People: They range from being strange-looking people to being anthropomorphic to looking like actual animals.
  • Pint-Sized Kid: Some of them.
  • Plant Person: Some of the Lemon Children resemble plants or mushrooms.
  • Royally Screwed Up: Assuming the Lemongrabs are brothers.
  • Shared Family Quirks: Their tendency to scream at random intervals. Apparently, the earls view the screams of their children as “piercing songs.”
  • The Scream: They take after their fathers in this department. Seems to be a lemon trait.
  • That Thing Is Not My Child!: 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.
  • Too Many Babies: Or in this case, way too many.
  • The Unintelligible: Because of their age, they can only communicate using one-word or monosyllabic sentences, strange noises, and shrieks.
  • Vocal Dissonance: 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.
  • Vomit Indiscretion Shot: Seed-Wad barfs all over himself after the Lemongrabs make him.
  • Wave of Babies: The Lemon Children all mob Finn and Jake in a large herd, rubbing against them and attempting to chomp on them.
  • What Measure Is a Non-Cute?: 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 Ugly Cute 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: Justin Roiland

  • Book Dumb: 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.
  • The Call Knows Where You Live: His attempts to run away from his debt to the Lemon People, failed because of his guilty conciense.
  • A Day in the Limelight: Has his own two-part episode.
  • Dark and Troubled Past
  • 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.
  • Has Two Daddies: Personality-wise, he's inherited traits from both.
  • I Just Want To Be Free: 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.
  • It's All About Me: 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
  • Meaningful Name: He is believed by all the Lemon Children and Lemongrab 2 to one day bring hope to all of them.
  • Messianic Archetype: For the Lemongrab Earldom.
  • Only Known by Their Nickname: His given name is "BadLemonNoHope", but prefers "Lemonhope" and is only called that by Lemongrab.
  • Only Sane Lemon: 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.
  • Sociopathic Hero: 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.
  • Shared Family Quirks: 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.
  • The Unfavorite: Out of all their children, Lemonhope is Lemongrab's least favorite, to the point that he's kept locked in a bathroom.
  • Ungrateful Bastard: Doesn't show concern with how Lemongrab is treating all his siblings as punishment for helping him escape.
  • Walking the Earth: Does this for the next thousand years after freeing Castle Lemongrab.

Na na na na nasty! Nasty jazz!
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. 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.

Voiced by: Kumail Nanjiani

  • Adorkable: He's an extremely awkward, exceedingly nice guy.
  • Back from the Dead: 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.
  • Because You Were Nice to Me: 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.
  • Benevolent Genie: He's nice to an almost absurd degree. How nice? He straight out tells Jake not to waste his one wish on something stupid, 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 "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.
  • Cheated Angle: He's almost always in profile but that seems to be by choice. He can turn his head despite his one-dimensional appearance.
  • Confirmed Bachelor: 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 Prismo seems more interested in Jake's company than anyone else's.
  • Could Say It But: He stretches this trope about as far as it goes.
  • Didn't Think This Through: 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.
  • Dream Apocalypse: 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 Citadel.
  • Heroic Sacrifice: He allows Finn and Jake to wake up his human form, thus destroying his Wishmaster form.
  • Fatal Flaw: 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.
  • Killed Off for Real: But he's got a backup plan in case he got offed...
  • Literal Genie: Played with. The wishes executed act like this in nature, but he admits he doesn't do it deliberately because it is out of his control. Careful, specific wording can get around the Be Careful What You Wish For part, and although he granted 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.
  • Nice Guy: Really nice. He seems like an all around great guy.
  • Nonstandard Character Design:
    • Paper People/Living Shadow: He basically looks like a moving picture of a person on the floor and ceiling.
    • Or something from Yume Nikki... In fact his human form looks like Dave Specter with a beard.
  • Oh, Crap: 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.
  • Reality Warper: He grants wishes that can alter the course of history.
  • Time Master: Sort of. He uses wishes to allow people to navigate The Multiverse and stays in his own time-sealed room, but doesn't really ever leave it.
  • Tulpa: He is an entity born from the dreams of an elderly man.

    Joshua and Margaret 
Jake's parents, who also adopted Finn after finding him in a forest. Their job is to hunt monsters around Ooo.

Voiced by: Kent Osbourne (Joshua) and Maria Bamford (Margaret)

  • Action Girl: Margaret qualifies, as she accompanies her husband on his monster-hunting expeditions. She seems to favor a crossbow and shuriken.
    • Pregnant Badass: Although her pregnancy prevents her from being as deadly as usual, she manages to defeat the monster who bit Joshua by herself.
  • Bad Ass: Joshua routinely defeats powerful demons. Margaret herself is no slouch and loves fighting monsters with her husband.
    • Bad Ass Normal: By 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.
  • Battle Couple: Both of them work together in their monster hunting business.
  • Cool Sword: Joshua was the original owner/creator of the Demon Blood Sword.
  • Deceased Parents Are the Best: 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.
  • Face Full of Alien Wing-Wong/Mr. Seahorse: Joshua is the one who gave birth to Jake, who popped out of his head after he got bitten by a monster.
  • Good Parents: 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.
  • Good Scars, Evil Scars: The reason why Joshua always wears a fedora is to hide a scar he got from giving birth to Jake through his head.
  • Motor Mouth: Joshua tends to talk like this.
  • Posthumous Characters: Both are dead by the time of the first episode, but they appear in flashbacks.
  • Truly Single Parent: While Jermaine was created the "normal" way, Jake himself sprouted from Joshua's head, a la Athena.
  • Would Hurt a Child: Double Subverted by Margaret: Upon realizing that 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.

    Big Destiny 
The off kilter leader of the Destiny Gang, a group of criminals in Finn's alternate wished universe.
Voiced by: James Kyson

  • Bad Boss: It's obvious that his henchmen are pretty terrified by him.
  • Jerkass: Big time.
  • Large Ham: He's pretty bombastic.
  • Offscreen Teleportation: Used and lampshaded.
    "Yeah! How did I even get here, son?"
  • Sinister Shades: Those evil-looking sunglasses should be a pretty big giveaway that Big Destiny's not a good guy.
  • The Social Darwinist: To some extent. When Finn challenges Big Destiny to a fight to demand his crown back, Big D beats Finn, but gives him the crown anyway, seemingly impressed by the bravery Finn displayed. Further, at the end of the episode, his cronies run from Finn without saving him, and Big D expresses approval.
  • Zettai Ryouiki: Rare Male Example. He appears to be sporting a Grade B.

    The Duke of Nuts 

The Duke of Nuts

A secondary character, 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.
  • Happily Married: His wife quickly jumps to his defense in the pudding case. Also, he 'lies with her' often.
  • Nice Guy: Ridiculously nice. Almost obscenely nice. Hell, he was willing to take the fall for Finn even though he was totally innocent.
  • Poke the Poodle: About the only thing he's ever done wrong is eat all of Bubblegum's pudding.
  • Quirky Household: 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.
  • Sitcom Arch-Nemesis: To Princess Bubblegum, who despises him solely because he ate all of her pudding once.
  • Sweet Tooth: He loves him some pudding.
  • Trademark Favorite Food: Pudding.



A brainy creature resembling a walking, talking heart. He's actually the Ice King's heart, granted sentience by a love spell gone wrong.

Voiced by: George Takei

  • And Now You Must Marry Me: In 'Lady and Peebles", he tells Princess Bubblegum that he wants to be "united as man and wife" with her.
  • Art Evolution: Compare his appearance in season 1's "Ricardio the Heart Guy" to his return in season 4's "Lady and Peebles".
  • Ax-Crazy: And how, he is much more crazy and deranged than the Ice King.
  • Beat Still, My Heart: His existence in a nutshell.
  • Big Ol' Eyebrows: Has these despite being an internal organ.
  • Break the Haughty: In "Lady and Peebles".
  • Evil Is Visceral: He's a living heart, for starters.
  • Evil Sounds Deep: Given who's he's voiced by, it's to be expected.
  • Eviler Than Thou: He's eviler than the Ice King. Which isn't that hard, but he's still pretty scary.
  • Faux Affably Evil: Puts up a charming front, but is anything but.
  • Feigning Intelligence:
    • He's not as smart as he likes to think. This is pointed out by Princess Bubblegum when he holds her hostage:
      Bubblegum: I feel like a big idiot for not believing you. He was just so engaging. Though his knowledge on planetoids is actually pretty weak...
    • And again when he reappears in "Lady and Peebles".
      Bubblegum: You thought we were intellectual equals!?
    • In "Lady and Peebles", Princess Bubblehum lampshades the poorly thought-out design of his new body.
      Bubblegum: This body you designed is self-congratulatory garbage! See, I know a thing or two about building a body out of biomass, and you don't leave your heart exposed!
  • Glass Cannon: His new body is strong enough to tie Lady Rainicorn in a knot, but his soft spots were still exposed.
  • Gross-Up Close-Up: A particularly memorable example of this trope when he reveals his plans:
    Ricardio: Now I'm going to cut out Princess Bubblegum's heart [close up] and make out with it.
  • Nonstandard Character Design: Has a more detailed face than other characters.

    The Flame Kingdom 


"The Ice King is schemin' to nabs a princess today! I swears it!"
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: Tom Kenny

  • And Your Reward Is Edible: Characters are shown feeding him charcoal as payment for his services.
  • Baleful Polymorph: "Incendium" implies that he, and all flambits, were created from normal fire elementals by Flame Princess in one of her tantrums.
  • Exact Words: "I know just the skirt! And she's way hot!
  • The Gadfly: 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. Also I spat on ya's.
  • The Informant: He helps Finn and Jake keep tabs on the Ice King.
  • Instant Runes: When casting.
  • Kill It with Water: In the video game Flambo's Hot Mess.
  • Mundane Utility: 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."
  • My Species Doth Protest Too Much: Flambo's fairly nice if mercenary, but supposedly everyone in the Fire Kingdom is evil.
  • Playing with Fire: It may just be an extension of his natural body, but Flambo can keep things warm and set them on fire.
  • Put on a Bus: Andy Ristaino has stated that Flambo is hard to get ahold of, explaining why he's not usually around to cast Flame Shield on Finn for his dates with Flame Princess.
  • Screams Like a Little Girl: 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.
  • Status Buff: The only magic ability he's shown so far was Flame Shield, which protects mortals from fire.
  • Unexplained Accent: He may not be from the Bronx, but his accent sure is.

Flame King

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

Voiced by: Keith David

  • Abusive Parent: 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 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.
  • Bad Boss: Was fine with "Finn" killing his court jester and in Playing With Fire he chastised his cook for dinner being ready 10 minutes early.
  • Cain and Abel: He extinguished his own brother to become King.
  • Card-Carrying Villain: He may not be of the diabolical Laughing Mad variety, but he's still pretty open about the fact that he's evil.
  • Evil Tropes: He, and all other people in the Fire Kingdom, are evil:
    • Affably Evil: He's quite polite for an Evil Overlord.
    • Even Evil Has Standards: 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.
    • Evil Is Burning Hot: The Flame King, anyone?
    • Evil Overlord: He rules over the Flame Kingdom.
    • Evil Parents Want Good Kids: 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!
    • Evil Sounds Deep: Comes with being voiced by Keith David.
    • For the Evulz: Playing With Fire shows him terrorizing the citizens of the Flame Kingdom just because he can.
  • Klingon Promotion: 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.
  • Large and in Charge: He's a big dude, to say the least.
  • Orcus on His Throne: 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.
  • Sealed Evil in a Can: Usurped by his daughter and put inside the same lantern he put Flame Princess in.

  • Eyes Always Shut: Her eyes only open a few times.
  • Larynx Dissonance: She's voiced by a man, rather like her best friend LSP.
  • Single Woman Seeks Good Man: She's never had any success with men, which is what convinced LSP to write a book on dating. Fortunately, she pairs up with a vulture who'd been hitting on LSP earlier.
  • Turtle Power: A turtle who's a princess and a head librarian.

Slime Princess

The Princess of the Slime Kingdom.

Voiced by: Maria Bamford

Wildberry Princess


The princess of the Wildberry Kingdom.

Voiced by: Maria Bamford

  • Anthropomorphic Food: Looks like a berry.
  • Berserk Button: In "Furniture and Meat" we learn that, yes, you can push hers. Jake tries to pay her gold in exchange for getting to sit on her head. Her response? Confiscating all of Jake and Finn's gold, melting it down and planning to execute them by pouring it over them.
  • Beware the Nice Ones: Dear lord, don't let her timidness fool you. If she perceives herself as insulted, she will not take it well.
  • Distressed Damsel:
    • She is often seen being kidnapped by Ice King, much more frequently than most of other princesses than Princess Bubblegum, most likely because of her Fragile Flower nature.
    • In "Jake vs. Me-Mow," Wildberry Princess is the target of an assassin from the Guild of Assassins.
  • Planet of Hats: The Wildberry Kingdom: a kingdom where everyone is a berry.
  • Princesses Rule: Apparently the only ruler of the Wildberry Kingdom.
  • Shrinking Violet: She speaks in a soft voice, and she's rather sensitive and easily prone to tears.

Hot Dog Princess

A princess who rules over the Hot Dog Knights.

Voiced by: Maria Bamford

  • Abhorrent Admirer: 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."
  • Cloudcuckoolander's Minder: Instead of the knights protecting their ruler, most of the time it's the other way around.
  • Distressed Damsel: She requires saving pretty regularly. Her knights are even worse.
  • Princesses Rule: Apparently the only ruler of the Hot Dog Kingdom.
  • Visual Pun: 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".

    • Last Kiss: After they get their kiss they dissolve into lifelessness without any further objection.
  • Princesses Rule: Claims to rule the Desert Kingdom.

Old Lady Princess

A princess that The Ice King gets engaged to.

Voiced by Kerri Kenney-Silver

  • Eye Scream: Her eyes get painfully huge.
    "I'm not crying, Finn. My tear sac is broken."
  • Mind-Control Eyes: You can tell she is hypnotized because when you examine her eyes closely enough you can see a miniature version of her behind bars in each one.
  • Open the Iris: The entirety of her eyes, white, iris, pupil and all get huge under mind-control.
  • Hypnotize the Princess: The Ice King gets her to accept his engagement with a cursed engagement ring.
  • Younger Than They Look: Old Ladies are their own race of people in Ooo, so Old Lady Princess may not actually be that old.

    Candy People 


"I can't help it. Flesh is delicious!"
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: Tom Kenny

  • Butt Monkey: Bad things tend to happen to him, like getting thrown in the dungeon, attacked by zombies, or getting Freezer Burn Flu.
  • Conspiracy Theorist: He takes calls from them on his radio show.
  • The Cuckoolander Was Right: Turns out he was right about PB being replaced by a lizard imposter in "We Fixed A Truck".
  • Felony Misdemeanor: Being thrown in the dungeon for three hours by the Earl of Lemongrab. Starchie doubted he would even survive that long.
  • Gasshole: Squeeze him and he'll fart.
  • Gone Horribly Right: 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.
    Starchie's feeling healthy again. [Bulks up further] A bit too healthy if you ask me.
  • I'm a Humanitarian: He can't help it. Flesh is delicious.
  • Nice Hat: One of his distinguishing features.
  • Third-Person Person: Always seems to refer to himself in the third person:
    [Upon being sent to the dungeon] If Starchie lives that long.

Mr. Cupcake

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

  • Badass Mustache: He sports a handlebar one.
  • Feel No Pain: 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.
  • Naked People Are Funny: In "Slumber Party Panic", while playing Truth or Dare, Chocoberry dares him to take off his wrapper.
  • Sesquipedalian Loquaciousness: 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!"
  • World's Strongest Man: He's supposedly the strongest of all the candy people.


A talking pinata, Manfried serves as a PA for the Candy Kingdom.

Voiced by: Maria Bamford

  • Bearer of Bad News: Usually this for Princess Bubblegum
  • Big "WHAT?!": In "Slumber Party Panic", upon hearing that they were going to smash pinatas. Finn quickly reassured him that he wasn't going to be smashed.
  • Cool Horse: Or in this case, a cool pinata.

Banana Guard

The Royal Guard of the Candy Kingdom, serving as both police and bodyguards to Princess Bubblegum.

Voiced by: Pendleton Ward

  • Blade on a Stick: They carry spears.
  • Color-Coded for Your Convenience: The Banana Guards of the past that appear in "The Vault" are color green.
  • Human Shield: They literally use themselves as barricades in "Princess Cookie". Though maybe it's more "Banana guard" shield.
  • Nothing Exciting Ever Happens Here: In "You Made Me", they didn't tell Princess Bubblegum about Lemongrab sneaking into Candy People's rooms because it would take away their "weird TV show", which they wanted to keep because, in their words, "Banana Guarding is boring".
  • Police Are Useless: The rarely manage to acomplish their job protecting the kingdom. Princess Bubblegum is so dissapointed by it that she assigns Root Beer Guy in charge of the Banana Guard.
  • Praetorian Guard: For Princess Bubblegum.

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 The Lich going on a rampage in the city. They are also the Guardians of the Royal Promise, punishing those who break Royal Promises. 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.

Voiced by: Tom Kenny & Steve Little

  • Felony Misdemeanor: When Princess Bubblegum pleads for Finn, they decide to give him a less hot trial: Math questions.
  • In Its Hour of Need: They only seem to get up when something really bad is out for the Candy Kingdom, but otherwise leave everything to the Banana Guards.
    • There's an explanation for why this might be in "The Vault" - not long after they were born, they overreacted and attacked Shoko with far more force than necessary, directly leading to her death - but it's unconfirmed.
  • Kill It with Fire: Their initial punishment for breaking a Royal Promise is to subject the promise-breaker to Trial by Fire.
  • Time Stands Still: They do this when you break a Royal Promise, causing everyone but the promise breaker and the one who demanded the promise to freeze solid.
  • Wave Motion Gun: Have a rather... impressive weapon that has only been seen once while being piloted by Finn's mind-control hat.
  • The Worf Effect: If anything is strong or evil enough to get their attention (Like The Lich, or Gunther), they get beaten fairly quickly.
  • Your Head Asplode: They suffer this when Finn gets the math question right.

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: Stephen Root

  • Ax-Crazy: A non-villanous (or evil) example.
  • Badass Mustache: Subverted, it was once badass, but then it got torn.
  • MacGuffin Guardian: His job was to guard the Royal Tarts in their journey from the Candy Kingdom to the Sacred Backrubbing Ceremony.
  • The Mentally Disturbed
  • Mind Screw: 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.
  • Serious Business: 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.


Voiced by: "Graham Linehan's daughter" (real name withheld)

Another of Princess Bubblegum's experiments, Goliad is a candy-Sphinx built to rule the Candy Kingdom past Bubblegum's death. She soon turns out to be impressionable, with a questionable grasp of morals.

  • A God Am I: Not really a god, but the sentiment is there.
  • Ambiguous Innocence: Sure, her endgame is evil, but there doesn't seem to be a smidgen of malice in her. Which only makes her creepier.
  • Body Horror: Her third eye, which seems to unnaturally pop out of her forehead.
  • Cain and Abel: Cain to Stormo's Abel.
  • Complete Immortality: Implied by Princess Bubblegum, but we only know for sure she's The Ageless.
  • Control Freak: After seeing how Jake treated the Candy children, she planned on treating the whole Candy Kingdom this way too.
  • Corrupt the Cutie: Although it's implied that Goliad was unnaturally susceptible to it. Still, Jake was probably the worst person to leave in charge of her.
  • Creepy Child: With an uncanny child-like voice coming from a huge monster and unstable psychic powers, she comes off as this.
  • Gone Horribly Wrong: With her powers and dedication to what she's taught, she had the chance to be the perfect successor to Bubblegum until Jake's bad leadership skills rubbed off on her and turned her into a power-hungry tyrant.
  • Harmful to Minors: Some of the first things she sees are Jake getting violated by an entire preschool class, and his retribution.
  • In the Blood: Probably inherited Bubblegum's single-mindedness.
  • Lack of Empathy: She's a very young child, after all.
  • Mind Rape: Tries it on Finn, who is able to hold his own for an admirable amount of time, before Stormo appears.
  • Orifice Invasion: She stuffs a whole bunch of people down Jake's throat with her psychic powers, in imitation of a bunch of children doing the same to him earlier.
  • People Puppets: Her main power is mind control.
  • Physical Goddess: Has immense Psychic Powers and was made with the explicit purpose of being immortal. She's so powerful that Princess Bubblegum is scared if she threw a tantrum, she'd destroy the entire castle on her own and is so powerful the only thing that can fight her successfully is another of her kind.
  • Psychic Powers: She can read people's minds and make them levitate.
  • Sealed Evil in a Duel: Bubblegum states that she and Stormo are forever locked in a psychic stalemate.
  • Sibling Yin-Yang To Stormo, and also to Lemongrab.
  • Social Darwinist: "The weak bow to the strong, and such is harmony."
  • The Evils of Free Will: Her motive rant consists of her explaining that living things don't care for anything other than themselves, and that peace as we know it is a sham. Further, when she uses her psychic powers to get a child through an obstacle course, she demonstrated a belief that absolute control is the best way to get things done.
  • Telepathy: She can move objects with the power of her third eye.
  • Unexplained Accent: Again as with Tree Trunks, her voice actor's British accent deviates from Ooo/Standard American for no in-universe reason.
  • We Can Rule Together: She tries fervently to win Stormo over, but he isn't having it.
  • With Great Power Comes Great Insanity: Due to Jake's improper tutoring she decides to take over the Candy Kingdom .


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.

  • Badass: The first thing he does is pounce on Goliad and kick her across the roof, through a small tower. The second thing is to engage her in an eternal psychic battle, sacrificing himself to save everyone else.
  • Big Damn Heroes: See Dynamic Entry.
  • Body Horror: The third eye, which works the same as Goliad's.
  • Cain and Abel: Abel to Goliad's Cain.
  • Dynamic Entry: He rushes in just in time to save Finn and the Candy Kingdom from Goliad.
  • Good Counterpart: Based on Finn's DNA rather than Bubblegum's.
  • Heroic Sacrifice: Locks himself and Goliad in an eternally stale-mated psychic battle. Truly impressive in that he doesn't even hesitate to do so.
  • In the Blood: Is every bit as noble and heroic as Finn. And also has his blonde hair.
  • Psychic Powers: With the power of his third eye, he can manipulate objects and other beings, just like Goliad.
  • Sibling Yin-Yang: It's unclear to what extent they are siblings, but they're as different as night and day.
    • The addition of Finn's DNA into Stormo's primordial goop is the only noted difference between them.
  • Telepathy: See Psychic Powers.
  • The Unintelligible: Speaks entirely in birdlike screeching sounds, though Goliad seems to understand what he's saying.

Princess Cookie

Voiced by: Donald Faison

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 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: Johnny Pemberton

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. His whole personality revolves around his intense infatuation with Bubblegum.

  • Ambiguously Human: Looks like a normal human except for skin color and sugar crystals in his head.
  • Body Horror: Ogdoads spell makes him into a hidious monster, but see below...
  • Deal with the Devil: With the shadow creature Ogdoad
  • Dogged Nice Guy: Deconstructed. His efforts are expressly against the princess's wishes and bring him nothing but pain.
  • Even the Guys Want Him: The effects of Ogdoads spell causes everyone to love him.
  • Too Dumb to Live: Every bad thing that happens to him physically is because he is so infatuated with Bubblegum that he doesn't think things through; which includes jumping into a fire pit and accepting Ogdoad's offer despite the demons warning.

Root Beer Guy

A background character who ends up the focus of the episode "Root Beer Guy". A Candy Kingdom telemarkater 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 Girl. 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. As a result, Root Beer Guy was promoted to the head of the Banana Guards.


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. 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.

  • Greek Chorus: Acts as one for his Graybles.
  • No Fourth Wall: He routinely speaks directly to the viewers.
  • Trickster Mentor: Sorta acts like this to the viewers because some of his Graybles are designed to mislead the audience.

    Jake Jr. 

One of Jake and Lady Rainicorn's puppies, and the only one (other than TV in a brief cameo) to have multiple appearances. She has recently become a thief like her father was in his youth.

Voiced by: Kristen Schaal

  • Eyeless Face: 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. Turns out her odd face may be inherited from her extra-dimensional "grandmother".
  • Gender-Blender Name: She's a girl named Jake.
  • Rapid Aging: 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.
  • Voluntary Shapeshifting: Her hair can grow and be controlled in the same way her father controls his body.

The creator of all MOs. Created BMO as the companion of the son he would never have before sending him out into the world to "Be more."

Voiced by: Chuck McCann

  • Cool Old Guy: We're talking about the guy who built BMO!
  • Genius Cripple: Can't use his legs and requires his robots to carry him and for life support.
  • Nice Guy
  • 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.

A.K.A The Sky Witch. She's the person Ash sold Hambo to in order to learn some useless spells. Marcie's since been trying to track her down to retrieve her doll.

Voiced by: Jill Talley

  • Art Evolution: Her second appearances gave more details to her eyes rather then the black dots she had before. This allowed for better expressions.
  • Ax-Crazy: Has shades of it if the ending of her introduction episode is any indication. Really says something when Marcie's not foolhardy enough to confront Maja on her own and asks Bubblegum to help her.
  • Bad Boss: Sends her familiar to keep Marcie distracted which resulted in him getting beat up. When he comes to her stating he wants to quit after she succeeds in getting Bubblegum's t-shirt. She starts chasing him around her dwelling blasting him with magic. And she was in a good mood at that point.
  • Blow You Away: Well she is the Sky Witch for a reason, though doesn't seem to utilize it often.
  • Chekhov's Gunman: She was the witch that Ash mentioned selling Hambo to.
  • Eldritch Location: Seems to reside in one.
  • Emotion Eater: Mentions in "Something Big" that her magic runs on sentimental value and caring. Thus she to takes over the Candy Kingdom for this purpose.
  • Even Evil Has Standards: When summoning Darren, she tries to reign him back on outright destroying the Candy Kingdom since she need Bubblegum for her plans. He doesn't listen however and nearly killed Peebo if Finn hadn't flown in for the save. Before that though, Maja actually looked quite horrified he was about to go through with it.
  • Evil Is Hammy: Big time.
  • Foreshadowing: Ash mentions her in "Memory of a Memory'' (not by name otherwise Marcie would've found her much earlier). The fact she has some plan to utilize the sentimentality value of the items she had an interest in seems to imply she won't be a one-shot character.
  • Jerkass Has a Point: A partial example. She says that since Ash sold her the doll, it is now legally hers, and, in-universe, this apparently hold up, leading Bubblegum to deal with the solution diplomatically. However, it's easy for the viewer to realize that it wasn't Ash's doll to sell in the first place, making the legitimacy of the deal questionable at best.
  • Manipulative Bastard: Maja tricks Bubblegum into giving up the T-Shirt Marcie gave her. Later Maja says that Bubblegum had a stronger emotional attachment to the shirt then Marceline had to Hambo which is why Maja plans to use the shirt in a spell for "something big!"
  • Mind Screw: Maja and her Crabbit familiar pull these on Marcie as she and Bubblegum make their way to Maja's house.
  • Not Quite Dead: Gets knocked into a tree after being blasted by the Tandem War Elephant which knocks her into a coma. Ironiclly said war elephant is the one who helps her later.
  • Non Indicative Name: Her title as the "Sky Witch" would indicate she has wind-based powers or something related to it, but she doesn't.
    • Subverted in her second appearance, she manages to knock Princess Bubblegum and her Marrow out of the air using wind. It's also how she's able to fly as well.
  • Prim and Proper Bun: Oddly enough.
  • Shock and Awe: Was abusing her familiar with electricity.
  • Voice of the Legion: Constantly talks in reverberating, demonic like tone.
  • Wicked Witch: Is she ever, and she did it all to get a shirt.

    King Worm 
Voiced by: Erik Estrada
A giant worm that absorbs one's life force through their dreams.

  • A Glitch in the Matrix: Has a great power into putting people in their dreams, but said dreams tend to be very off to keep his target prisoner.
  • Dream Weaver: His bread and butter.
  • Early-Bird Cameo: Showed up at the end of Evicted in the first season before getting his own episode in season 4.
  • Lotus-Eater Machine: He is one. He tries to put his victims into a nice or normal setting while he sucks their life energy.
  • Poke the Poodle: In his first appearance, he hypnotizes Finn and Jake to hug him.
  • Your Worst Nightmare: Imagining them is the key to defeating him.

A serious hitman with powers over fire.

  • Assassin Outclassin': Ice King attempts to have Scorcher killed by contacting another hitman to take him out. Said hitman is almost immediately defeated when Scorcher burns through his Powered Armor, leaving the small guy inside to run away in fear.
  • Expy: Possibly one of Combustion Man, what with the whole "stoic voiceless fire based assassin" thing.
  • Fireball Eyeballs: When he gets mad.
  • Foil: Hyper-competent fire elemental to counter Ice King's inept ice magic.
  • Just Following Orders: Implied, though maybe he just likes to kill
  • Knight of Cerebus: Parodied. He's completely stoic, is absurdly competent, actively tries killing Finn and Jake in his sole episode, and has no personal comedic quirks. The thing is, unlike The Lich, who instantly makes the atmosphere and story darker once he shows up, Scorcher is instead used as a Straight Man to Ice King, who treats him as if he's an old friend of his.
  • Playing with Fire: Obviously.
  • Professional Killer: He is a hitman.
  • Red Eyes, Take Warning: Red eyes, meaning he has fire power.
  • Super Smoke: He has the ability to turn into a black smoke.
  • The Voiceless: He never talks.

    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. A human version of Choose Goose, named "Choose Bruce", appears in the alternate "Farmworld" universe.

    The Ancient Sleeping Magi of Life Giving 
Voiced by Dana Snyder

First appearing as a ghost in third season episode, "The Creeps", Shoko was a one-armed vagabond and mercenary with a tiger companion when she was still alive, and stole a powerful amulet from Princess Bubblegum in the time of the Candy Kingdom's founding. She dies in the attempt by falling into a radioactive river, but as "the Ghost Lady," she haunts the vault of Finn's mind, yearning for atonement. Finn is actually her reincarnation.

Voiced by: Isabelle Fuhrman

  • Action Girl
  • Action Pet: Her tiger, who is also her mount.
  • Ambiguously Human: Even though she has a name and upbringing from a distinctly human ethnicity, it's not quite certain what kind of humanoid she is.
  • An Arm and a Leg / Artificial Limb: Her parents trade her right arm for a laptop, and she's taught that it's a worthy trade. Bubblegum disagrees and makes her a robot arm in return for helping build the Gumball Guardians.
  • Ascended Extra: Originally part of a one-off Gainax Ending gag in "The Creeps".
  • The Atoner / Ghostly Goals: The reason why she haunts Finn's dreams.
  • Body Horror: Falling into a moat of radioactive Mutagenic Goo turned her into a weird worm-like creature. On the plus side, her right arm grew back.
  • Chekhov's Gunman: Turned out to be a lot more important than she first appears...
  • Continuity Nod/Mythology Gag: She shares the trademark artificial arm that most alternate versions of Finn possess, highlighting her relation to him as his prior incarnation.
  • Foreshadowing: Shoko is missing an arm, as do all alternate universe versions of Finn. As of "Escape From the Citadel", Main!Finn is finally missing one too.
  • Handicapped Badass
  • Hilariously Abusive Childhood: Her parents traded her arm for a laptop, teach her that computers are worthy of such a tradeoff, and she just thinks such a sentiment is completely normal.
  • Nuclear Nasty: She emerges from the radioactive river as one, but quickly dies. She then haunts Finn in that form.
  • Our Ghosts Are Different: Her first appearance in "The Creeps", as well as in her cameo appearances afterward. "The Vault" implies that the castle from "The Creeps" was originally the base of the Bath Boy Gang who gave Shoko her final job, which suggests that she wasn't exactly a ghost, but part of a past life vision Finn was having.
  • Parental Abandonment: Left at a dojo by her parents.
  • Past-Life Memories: Most of what's known about her is from Finn's mental "Vault".
  • Reincarnation: The most recent past life of Finn.

Voiced by: Noah Nelson

A demon who created the Demon Sword with his own blood, which was taken by Jake's father, Joshua. He really, really wants his blood back.

  • Hoist by His Own Petard: Finn kills him by exploiting his method of Blood Magic to trick him into inhaling blessed grape juice.
  • Holy Burns Evil: Is injured and weakened by holy water. Finn kills him by tricking him into absorbing blessed grape juice.
  • Killed Off for Real: At the end of "The Pit" he's gone for good. He wasn't sealed into anything this time..
  • Oh, Crap: Upon realizing that he just inhaled blessed grape juice.

    Ooze Monsters 
Humanoid creatures created in the aftermath of the Mushroom War, oozing green slime from all their orifices. They plagued Simon and young Marceline in their travels, and they're still around, awoken by PB, Finn, Jake and James.

    Cosmic Owl 
Voiced by Jeremy Shada in What is Life, M. Emmet Walsh in all other appearances

A mysterious and important entity in the land of Ooo, it appears to others in visions. It speaks in a Southern drawl initially and is a friend of Prismo.
  • Animalistic Abomination: 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.
  • Energy Being: It is an owl that is made out of yellowish cosmic energy.
  • Ominous Owl: Subverted, it's less of a malevolent force and is more of a natural force with some hobbies.
  • Only Friend: Prismo is his.
  • Physical God: Easily one of the most powerful entities in the series, but it does not directly interfere in the plot.
  • Vocal Dissonance: One of the most ancient and powerful entities of the series, but it has a youthful, Southern drawl.

    Finn Mertens/Ice King 
Finn Mertens is Finn's counterpart in the "Farmworld" universe.

    King of Ooo 
Claims to be the king of Ooo. Legally able to perform marriages.

    Betty Grof 
Voiced by Lena Dunham

The fiancée of Simon Petrikov aka the Ice King. She lived on Earth before the apocalypse until Time Travel brought her to the present day Land of Ooo.

  • Action Girl
  • Ascended Extra
  • But Now I Must Go: After restoring the powers of the ice crown to keep Simon alive, she decides to leave the Ice King until she is able to find a way to safely free him.
  • Decomposite Character: A lot of her moves and mannerisms are the same as Fionna's. Perhaps that's why the Ice King wanted Fionna to be real so much... not that he realized it.
  • Determinator: A trait she shares with her fiancée.
  • Fiery Redhead
  • Fish out of Temporal Water: Though she seems to take it well.
  • Hot Scientist: She co-authored a book about space time portals. She's pretty adorable, too.
  • The Lost Lenore: To Simon, although as the Ice King he's not really aware of it. It's ultimately subverted when Simon opens a Portal to the Past, intending to say goodbye to Betty... and she jumps through it to enter the present, meaning that she never really died after all.
  • Meganekko
  • Not Quite Dead: It was heavily implied she died early in the Mushroom War, hence why Simon never saw her again. Turns out it was because she jumped through a time portal, traveling to the future.
  • Official Couple: With Simon...kind of. It's complicated.
  • Posthumous Character: Subverted.
  • Stable Time Loop: She left Simon when he became Ice King because the Simon from the future was saying good bye to her through a Portal to the Past; thus she jumped through it to be with him there.
  • Star-Crossed Lovers: Implied in "Holly Jolly Secrets", with Simon having come to believe that she met her end in the Great Mushroom War. In "Betty", it turns out she didn't die after all... and she makes it her goal to save Simon from his fate.
  • Undying Loyalty: To Simon. We're initially lead to believe she left him after the crown started taking control of him. Turns out she slipped through a time portal to the current timeline, and has never faltered in her love for him.
  • Unfazed Everywoman: After escaping to the future she doesn't appear visibly fazed by any of strange things around her. Kind of justified, as she had much more important things on her mind at that moment. But then given the title of the book she and Simon co-wrote, "Mystic Rituals And Their Space Time Applications", she was likely never "normal."
  • Walking Spoiler: Her role in the Ice King's origins makes her this. Her arrival in Ooo via time travel makes her all the more important.
  • Walking the Earth: After Simon is forced to wear the crown again to save his life. She begins traveling Ooo in the hopes of finding a way to cure him.

    Bella Noche 
Voiced by Maurice LaMarche

An evil anti-magical being summoned by Bufo, Laser Wizard, and Forest Wizard. He nearly destroys wizard city before being stopped by Betty.

  • Anti-Magic: A being purely composed of it.
  • Bishonen Line: His regular form is a massive face made out of moss while his "true" form is a beautiful, androgynous humanoid.
  • Crippling Overspecialization: His Anti-Magic powers mean that no wizard can hope to harm him. However, he doesn't have any other abilities, so a normal human like Betty can just cold-cock him with little effort.
  • Power Nullifier: He can strip magical beings and objects of their power.
  • Sinister Geometry: A massive black cube surrounds him. A failed attempt to destroy it makes it grow into more complex shapes.
  • Translation Trainwreck: His name translates as "Beautiful Night" or "Night of Beauty". Except that "bella(beautiful)" is Italian, and "noche(night)" is Spanish.
    • "Bella" is also the Spanish word for "beautiful".

A Lumpy Space Person who becomes LSP's boyfriend. Ends up being teleported to an unknown dimension because of LSP recklessly sticking him in Bubblegum's time machine.

    Phlannel Boxingday 
Voiced by Creed Bratton

A monster hunter who rides around a cloud in the sky. He rescues Lemonhope from the desert and later inspires him to free the Lemon Children. Might be a bubblegum man, and implied to have a connection to Princess Bubblegum, with the same initials, an instance of Techno Babble and fluency in German, and being bound by the same pacts and treaties that prevent Bubblegum from interfering with Castle Lemongrab.

  • Cool Old Guy: Flies around in a cloud-cart, killing treasure-eating monsters for their treasure and harvesting black diamonds for love potions.
  • Foil: To Princess Bubblegum. She raises Lemonhope under the strict belief that he is required to free the lemon people and take over as ruler while Phlannel encourages him to do what he wants and live as a free spirit.
  • Order Versus Chaos: He offers to Lemonhope the life of a chaotic free spirit in contrast to Princess Bubblegum's forcing him to become a martyr for his people.
  • Red Oni, Blue Oni: A passionate wanderer who values freedom above all else compared to the strict and pragmatic Princess Bubblegum who believes the safety of the people outweighs the happiness of the people.
  • Theme Initials: Compare "Phlannel Boxingday" with "Princess Bubblegum".

    The Grass Sword 
A cursed sword made of grass provided to Finn by the Grassy Wizard. It cannot be removed, but becomes controllable once Finn accepts it as his weapon.

  • Absurdly Sharp Blade: Sharp enough to slice through metal, and incredibly precise.
  • Adaptive Ability: It reacts to Finn's intense desire to not let his father escape in "Escape from the Citadel", taking over his whole arm, swelling up enormously, and giving him enough strength to restrain an asteroid from taking off. Unfortunately, the force of the asteroid's departure was so great that it ripped Finn's arm off; even then, the grass sword somehow made it so that the stump was completely healed over at the moment his arm was ripped off.
  • Ambiguously Evil: Though it did at one early point attempt to overwhelm Finn, the majority of the time it seems to act in his interest even when acting without his permission.
  • Cool Sword
  • Empathic Weapon: It responds to Finn's will, retracting to wrap around his arm when not in use. It also seems to possess some concern for Finn's safety, slapping him awake when he's unconscious in the ocean. It also destroys the Fear Feaster as he antagonizes Finn.
  • Evil Weapon: Originally, but Finn manages to keep it under his control.
  • Living Weapon: Definitely alive, and possessing some level of sapience.
  • Lost Forever: After Breezie seemingly pollinates it, it grows into a tree around Finn's stump and restores his arm. The remains fall on Breezie and . . . that looks to be the end of it.
  • Stealth Pun: Hardly "stealth" since it's the name of its introductory episode, but it's literally a blade of grass.
  • Talk to the Fist: Or blade, rather. It manages to slice through the Fear Feaster, much to his surprise, possibly without Finn commanding it to.

Voice by Ako Castuera

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

  • Action Girl: She was a partner in some of Billy's adventures.
  • Battle Couple: This is pretty much how she described her relationship with Billy.
  • Biker Babe: In flashbacks, she could be seen riding shotgun on Billy's motorcycle and when she and Finn visit Billy's Crack, she is drawn right to it.
  • Green-Skinned Space Babe: Well, green-ish. With pointed ears for extra alien-ness.
  • Manic Pixie Dream Girl: The "pixie" part is debateable, given her size, but there are indications that she was this to Billy. And maybe, momentarily, for Finn.
  • Mayfly-December Romance: In her flashbacks, Billy looks much younger, but Canyon hasn't visibly aged at all.
  • Statuesque Stunner: She's 20 feet tall and gorgeous.

    Martin the Human 
Voiced by: Stephen Root

Finn's father, trapped on the Citadel for unexplained reasons. He's freed during Escape from the Citadel.

  • Archnemesis Dad: He's the first person that Finn wanted Revenge against and got away with it. In result, Finn's hatred for him burns so deep that Finn can easily sing a sweet, calming lullaby about violently tearing Martin's arm off without batting an eye.
  • Ambiguously Evil: As noted in the mysterious past entry below, Martin's true nature is ambiguous as to whether he's a truly heinous criminal or just someone who got sent there under false pretenses. Even his distant behavior towards his own son Finn is arguably justified under the pretense of him being locked away for so long that he's become aloof and out of touch with other people; or given his mysterious past Martin may be trying to hide something he's ashamed of from his son Finn or trying to protect him by distancing himself. We honestly don't really know enough about the guy at this point to fully classify the man.
  • Beware the Silly Ones: Implied. He's incredibly cheery in his one appearance, and seems incredibly affable, and might even be likable if not for his actions during said first appearance... until you consider that he's in a cosmic prison full of incredible monsters up to and including The Lich, and a group of said monsters instantly accept him as their leader with no argument. And of those criminals, he was the only one not to be placed under the Lich's control. Whatever he is or however he got there, there's definitely more to him than it seems.
  • Broken Pedestal: The apple falls far from the tree, to say the least.
  • Disappeared Dad: He abandoned Finn when he was a baby. In the Citadel he refuses to give him any real explanation, then abandons him again. He seems to be actively avoiding him for some reason.
  • Dissonant Serenity: Has a rather cheery disposition despite apparently being one of the most dangerous criminals in the universe. He talks in a very casual tone as he is being pursued by the prison guards at the Citadel, shows the barest minimum of pain at a serious injury dealt to his leg, walks up to bad guys (and becomes their new leader) and exchanges pleasantries with them like it was nothing, and gives two notable winks that disarm the people they're aimed at and get them to follow his orders.
  • Evil Counterpart: Basically the Anti-Finn. While Finn is decked out in all blue, he wears all red. While Finn has a giant mane of hair, Martin is bald and bearded. While Finn is selfless and heroic, Martin self-absorbed and manipulative, etc.
  • Faux Affably Evil: Despite his cheery disposition, his true motivations are unknown, he's apparently a cosmic criminal, and he'll screw over someone who just helped him out without a second thought.
  • It's All About Me / Never My Fault: When Finn finally asks why he was left in the forest, Martin gets incredibly defensive and suggests that "maybe you abandoned me, did you ever think of that?!" — Finn was a toddler, and this seems to prove to him that Martin might not be such a good guy after all.
  • Major Injury Underreaction: Martin gets the skin on his right leg sheered off by a laser, all the way down to the bone. Sure enough, he treats it like an injury that needs to be dealt with, but he shows the barest minimum reaction to it; at best saying "this really stings", rather than screaming bloody murder at how painful it is like most people would. Even taking into account the Guardian Blood, that he gets Finn to apply to his wounded leg, restoring the flesh to his bone, Martin's casual reaction to the wound is rather astounding.
  • Mysterious Past: Very. For starters as one of the last (pure bred, as many of the current inhabitants are implied to be the mutated descendants of humans) humans on Earth what group of survivors did he come from? Is that group still around? What kind of life did he lead prior to having Finn? Who was the mother of Finn and how did he meet her? Was he missing because he was sealed away, or did he abandon him before that? Is he truly a cosmic criminal or was it some kind of frameup or misunderstanding?
    • Additionally, how exactly did Billy know that Martin was Finn's dad? And how did he know that Martin was imprisoned on the Citadel?
  • Planet Spaceship: Currently piloting the Comet, which crashes into the Earth every 1000 years.
  • Screw This, I'm Outta Here!: The moment he sees the Lich at the Citadel, he bails before things get real.
  • Ungrateful Bastard: He uses Finn to heal his leg and then completely ditches him for the Citadel inmates.
  • Walking Spoiler: He's Finn's dad, for crying out loud.

    Ancient Psychic Tandem War Elephant 
Voiced by: Steve Agee

An ancient two-headed psychic war elephant.

  • Bad Ass: Is the only thing that can face Darren the giant tree monster in a fight.
  • Put on a Bus: After his first appearance in "The Limit", he doesn't appear again until "Furniture & Meat".

    The Shape-shifter 
A strange monster that Joshua and Margaret encounter during one of their investigations. Has only appeared in "Joshua and Margaret Investigates" so far.

  • Aliens Are Bastards: Threatens a pregnant lady, 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.
  • Alien Blood: It bleeds bright green blood after Margaret pricks it with a pin.
  • Disappeared Dad / Missing Mom: Assuming gender even applies, it's one of these to its child 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.
  • Eldritch Abomination/Starfish Aliens: Which one is unclear because we can't quite tell if its origins are extraterrestrial or extra-dimensional. Regardless, assuming the last form it takes in the episode is its true form, it's one of the most bizarre beings in the series.
  • Face Full of Alien Wing-Wong: Inflicted this on Joshua, with Jake being the result.
  • Superpowerful Genetics: Passed on its powers and some of its physical traits to its son Jake and his children.
  • Voluntary Shapeshifter: 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.
  • Walking Spoiler: It's Jake's parent.
  • Wounded Gazelle Gambit: Took on the form of a baby when Margaret had it cornered. Margaret (apologetically) punched it out anyway.

    Peace Master 
A man who hunts monsters and is very paranoid about dark magic.

  • Arch-Enemy: To Peppermint Butler.
  • Cool Hat: Just look at that thing! It's even a...
  • Bag of Holding: His hat is a portal to a flesh-destroying void dimension.
  • Overprotective Dad: He is very concerned about his childrens fascination with magic, blaming said fascination on his paranoia of dark magic.

Millions of years ago, Earth was protected by four elemental guardians representing Ice, Flame, Candy and Slime. The strongest in their number was 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.

  • An Ice Person: The original one on Earth/Ooo
  • Heel Realization: When Gunther is driven to madness by the crown, he tries telling him to use focusing chants to regain his sanity "like I taught you", only to realize he never got around to teaching him anything.
  • Ironic Name: "Evergreen" is the kind of name you'd expect someone with a Green Thumb to have, not ice powers.
  • Jerk Ass: Takes Gunther for granted and continually keeps him at a distance and refusing to teach him magic. He also freezes his colleagues when they choose not to get involved with Wish Magic.

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. Accompanied by a yellow proto-mammal cat named Nina.

  • An Ice Person: Becomes the original Ice King after making his wish on the crown
  • Hero-Worshipper / Undying Loyalty: He remains extremely loyal to Evergreen, no matter how badly he gets mistreated by him. In the end, his wish to emulate Evergreen is so great that it overpowers his desire to save the world, turning him into the first Ice King and allowing the comet to destroy all life.
  • Madness Mantra: After wishing to become more like Evergreen. Gunther, no! Gunther, no! Gunther, no! Gunther, no...
  • One Steve Limit
  • Reincarnation: Another of Finn's past lives, with Nina being his Jake.
  • Uplifted Animal: Gained intelligence and speech when Evergreen mutated him in the egg.
  • With Great Power Comes Great Insanity: When using the wishing crown, his desires to be like Evergreen emerge, turning him into the original Ice King, and all he can do is continually chant "Gunther No" while using ice magic

    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 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. (Enough to drink royal jelly and become a Queen Bee to protect him from other bees.)

  • Action Girl: Post transformation.
  • Adorkable: Seems to share many aspects with Finn, including getting very nervous when in a more emotional situation.
  • Interspecies Romance: 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. 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.
  • Jerk with a Heart of Gold: Only wants to help Finn to keep the flower alive, but grows out it as she spends more time with Finn.
  • The Power of Love: 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 its Breezy afterward, with an awed expression.
  • Psychic Powers: In her Queen Bee form, though it isn't certain whether this only extends to other bees or not.
  • Rebellious Princess: 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. She eventually gets over this for Finn's sake.
  • She's Got Legs: In her Queen form, she has a shapely waist and legs after getting her new body. Justified in that, much like real bees she has pollen sacs in her legs (though hers look more like belt pockets.
  • Transformation Sequence: 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.
  • Walking Spoiler: Wouldn't expect that out of a simple bee would you?
  • Wingman: What she becomes to Finn after they first meet.

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. Kent quickly learned to talk, grow appendages, and after Shelby gets advice on brothers from Jake, Go and beat bad guys, which begins his first adventure into the tree itself.

  • Chaste Hero: due to being born literally a few minutes earlier, when the Rat Knight gives him a choice of love or the magic earth he has, Kent picks the earth without a second thought.
  • Does This Remind You of Anything?: 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 Kirby, both are small, round, pink, baby-like characters that go on an adventure blissfully to defeat a nightmarish villain.
  • The Hero: to the little people living in the tree.
  • Maybe Magic, Maybe Mundane: 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.
  • Sorting Algorithm of Mortality: Lampshades that he has no real sense of mortality, and slides between areas 1 and 2 of the scale.
  • Troll/Troubling Unchildlike Behavior: 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.

    Rat King 
As his title implies, He is the King of all rats that live in Finn and Jake's Tree, gnawing at its roots. He is encountered by Kent in his quest to defeat a bad guy. Normally appears as a normal rat with a crown, but can take on the nightmarish form of a Giant Rat Heat and cape on top of a Swarm of Rats.

  • Creepy Monotone: A high, but eerily calm and soothing tone...it almost never breaks unless he's attacking or being directly hit.
  • Karma Houdini: Gets away alive but with broken teeth, but stopping his gnawing allows the Tree House to bloom for the first time. Since a rat's teeth can grow back very quickly, it's likely he'll be back.
  • My Species Doth Protest Too Much: A villainous version, all the other Rats in the same episode appear to be nice enough to not fight Kent, and are just protecting the materials needed to make the strongest sword the Blacksmith can make, compare this to his direct hand in draining the Tree House' power by eating away at it.
  • Nothing Is Scarier: similar to the Lich, Rat King has no funny moments when he appears, and seems to be in a creepy sort of control. His motivation is never explained, and neither are his powers or his origin. Theres also the fact that he resides in some sort of otherworld inside of the tree and takes the form of a disembodied head on top of a mass of rats.
  • Power Parasite: He seems to have gotten his power from leeching off the Tree House itself, judging by his first scene.
  • Red Eyes, Take Warning
  • Shout-Out: His Head-on-a-Cape form is similar to Nightmare, just like Kert is to Kirby.
  • Swarm of Rats: His second form, which also means that He's Nigh Invulnerable to blows to his body.
  • We Can Rule Together: offers this to Kent, who of course refuses.
  • The Worm That Walks: his second form, which for added creepiness, is usually encased in shadow unless some form of light is brought directly to it.
  • You Dirty Rat: a more menacing version than most though.

    Rat Wizard 
A Rat living in the Tree House, who wears a robe and is encased in a crystal. He guards the Unbreakable Ore (a bottle cap).

  • Black Cloak
  • Just a Stupid Accent: Has an Indian accent.
  • Mineral Macguffin: The "unbreakable ore" which in reality is just a bottle cap.
  • Secret Test of Character: Offers The crystals in his room to Kent offering him the chance to live out his days in comfort, he's briefly entranced, but states that he didn't resist greed so much as he doesn't care about money. Rat Wizard thinks its weird but gives him the Ore anyway.

    Rat Knight 
A British-accented Rat in armor who wields a large sword, he guards the mystic earth (which appears to be just a mud clod mixed with his spit).

    Ninja Rat 
A mysterious and to-the-point Rat wearing Ninja garb. he protects the Sacred Flame (a blue firefly).

  • The Stoic
  • Instant Awesome, Just Add Ninja: possibly, seeing as the other two guardians are more classical in tone (a wizard and a knight)
    • One Of These Things Is Not Like The Others: likewise, his offers are a reverse of the other two, while Rat Wizard and Knight offered genuine articles of wealth and love, the materials they guarded, were mundane. Ninja Rat's offer, by contrast is mundane looking sap, while his offer is a magical-looking firefly.
  • Maybe Magic, Maybe Mundane: Unlike the things the other two Rats were carrying and offering (with the materials being mundane looking.), The firefly he offers appears to be magical, glowing a deep blue and actually being used as a forging fire.
