    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

  • Amazonian Beauty: Her connection to Beautopia is a likely influence to this trait.
  • 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".

Shelby is a talking worm who lives in Jake's viola.

    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

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

  • Deal with the Devil: In "Sons of Mars", Death agrees to resurrect Jake in exchange for Abraham Lincoln's immortality. It's also implied that he once revived someone for Lincoln in exchange for a penny.
  • Dem Bones: He appears as an anthropomorphic skeletal equine.
  • Don't Fear The Reaper: When we actually see him doing his job; as opposed to people invading his territory and trying to resurrect people; Death is rather friendly. He prepared a special trip for Simon with music and everything and both he and his target do consider it a Mercy Kill. When said target decides to let the attempt to save him go on anyways, Death steps back to see what happens.
  • Intangible Man: Apparently you can't kick him if your brain is stupid.
  • Kiss of Death: Subverted. A kiss from Death gives you your memory back.
  • Light 'em Up: Lives in a castle of light. This doesn't affect his morality much.
  • Man in White: Is decked out in all white clothing.
  • Nice Hat: Rocks a cowboy hat.
  • Rock Me, Asmodeus!: For a skeleton, he's quite skilled with a guitar.
  • Serious Business: Musical battles.
    Death: Those the rules of the Land of the Dead; lose a music battle, lose your life.
  • Stealth Pun: Plays Death Metal in a musical battle.

NEPTR (or Never Ending Pie Throwing Robot), pronounced "Nepter", is a robot that throws never ending pies. Created by Finn to get back at Jake for being pranked.

Voiced by: Andy Milonakis

  • The Bus Came Back: In "Hot To the Touch". Justified in-universe since he was forgotten about during a game of hide and seek by Finn and Jake for 15 months.
  • Butt Monkey: Other than Finn, he doesn't seem to be liked by many. After "What is Life?", the Ice King, who Neptr thinks of as "pappi", rejects him and mistakes him for BMO. BMO himself, Finn and Jake's other household robot, blew him off when he offered to hand, hinting that BMO in fact views him as inferior.
  • Determinator: Spent over 15 months playing a game of hide and seek which Finn and Jake forgot about.
  • For the Lulz: Learned the joys of pranking when he threw a pie at the Ice King.
  • Fun with Acronyms: As stated above, his name stands for Never Ending Pie Throwing Robot.
  • Gadgeteer Genius: Managed to create two sets of armor to protect Finn and Jake from Flame Princess.
  • Lethal Chef: NEPTR can make poison pies.
  • Like a Son to Me: How the Ice King saw him.
  • Robot Buddy: Is more of a pariah then a buddy.
    NEPTR: Hey BMO, we should hang out more. We're both robots.
    BMO: No, NEPTR. I am not like you.
  • "Well Done, Son" Guy: To The Ice King for much of "Mystery Dungeon".

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.

A legendary hero and Finn and Jake's idol. He battled hundreds of famous villains, such as the Lich and the Fire Count (also a bear), but eventually believed that it was a waste of time, as new villains would rise up. He later took up a philosophy of nonviolent community activism, but returned to the hero fold after Finn convinced him that saving lives was worth it.

Voiced by: Lou Ferrigno

    The Magic Man 
A mysterious, magical Jerkass from Mars. He was exiled after performing many magical pranks on the Martian people, in the hopes that he would learn how to care for others again, but instead spent two hundred years bumming around Earth being a jerk to the people of Ooo.

Voiced by: Tom Kenny

  • Ax-Crazy: He has a very sadistic and psychotic behaviour.
  • Bright Is Not Good/Light Is Not Good: Seriously, look at him. Especially when shedding his hobo outfit.
  • Card-Carrying Villain: The guy REALLY likes to let people know he's an incredible jerk, AND PROUD OF IT!
  • Expy: A partial one of The Joker. He runs around teaching people Family Unfriendly Aesops by doing nasty things to them (The Joker's motive is that he feels that things like society and human kindness are just jokes, and he wants to make the whole world agree with him), and he apparently used to be an okay guy, until he had one bad day that changed everything.
  • The Farmer And The Viper: The Magic man has pulled this gambit off twice now, once on Finn and on the stag that once kidnapped the entire Candy kingdom
  • For the Evulz: Seems to be his M.O. His entire reason for making everyone miserable, even the people who pay him kindness, is to teach them that he is an incredible jerk.
  • Freudian Excuse: In "Sons of Mars" shown that he used to be a decent guy with a loving girlfriend until something involving her drove him to be the sociopath he is.
  • Hate Sink: His track record of unjustifiable cruelty and jerkassery combined with his long status as a Karma Houdini makes it difficult not to hate him.
  • The Heavy: Aside from turning Finn into a foot and letting Jake be the scapegoat in his execution that resulted in the death of Abe Lincoln; his actions in "All The Little People" inadvertently caused Finn's selfishness to rise to the surface and resulted in his breakup with Flame Princess, Ice King's home destroyed and Lemongrab's last remnant of sanity slipping due to a prank due to Jerkass Ball. The last straw was eating Jake's sandwich and he gets punished for that.
  • Hidden Depths: "Sons of Mars" hints that there's a lot more to his character than he lets on.
  • Jerkass: Everyone thinks he's a jerk, and he even admits it.
  • Karma Houdini: "I win again, just like always!"
    • Averted finally in "Time Sandwich" when he finally gets what's coming to him when he messes with Jake.
  • Kick the Son of a Bitch: Remember that stag who single-handedly abducted the entire Candy Kingdom? Same one that the Magic Man transformed into a telescope in "Sons of Mars".
  • Lack of Empathy: He was banished from Mars to Earth until he could learn how to feel for others again. The only problem is he spent the whole time being a jerk to the people of Ooo.
  • Laser-Guided Karma: The first thing Finn and Jake do after returning to Earth from is knock Magic Man unconscious with a single punch.
    • He's also on the end of one hell of a beatdown at the end of "Time Sandwich." First, Jake gets his Sandwich back, then Marceline elbows him in the face and then BMO runs him over with his skateboard.
  • Morality Chain: His dead girlfriend is heavily implied to have been this for him.
  • Non Answer: This gem.
    Finn: So, how long have you had this house for?
    Magic Man: Yes, that is true!
  • Oh Crap: When Jake figures out his riddle, his eyes widen for the first time in the series.
  • Trickster Archetype: He teaches people the ever important life lesson that he's a jerk, a lesson the whole family can agree on. No, really.
  • Troll: He really enjoys pissing "sissy do gooders" off.

    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
  • The Chew Toy
  • Clones Are People Too
  • 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: Although not so obvious like 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: Like Lemongrab, he comes across as being mildly annoying, but unlike Lemongrab, that's the only problem he appears to have.
    • The "jerk" part seems nonexistent in "Too Old." 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 and Psycho: Quite possibly.
  • 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.
  • Tortured Monster: Possibly. Some of them don't have arms or legs and have impaired communication skills.
  • Troubled Child: Quite possibly.
  • 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. He wasn't the only child being actively abused, but...


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

  • A Day in the Limelight: Has his own two-part episode.
  • Dark and Troubled Past
  • 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.

Voiced by: Kumail Nanjiani

  • Adorkable He's extremely awkward, and an exceedingly nice guy.
  • 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.
  • Cheated Angle: He's almost always in profile but that seems to be by choice. He can turn his head despite his 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.
  • Jackass Genie: But only if your name is "The Lich".
  • 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. However, since he likes Jake; he tells him precisely how to word his wish to get what he wants.
  • Nice Guy: Really nice. He seems like an all around great guy.
  • Nonstandard Character Design:
  • 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.
  • What Happened to the Mouse?? He's stuck with the Lich in his room now.
    • Since the Lich was transported back to where he came from after making his first wish, it stands to reason that he'll be transported back again after making the second. The episode just didn't show it.

    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.

    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.

  • Larynx Dissonance: She's voiced by a man, rather like her best friend LSP.

Hot Dog Princess

A princess who rules over the Hot Dog Knights.

Voiced by: Maria Bamford

  • Distressed Damsel: She requires saving pretty regularly.
  • 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.

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

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

  • 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!"

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.
  • 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.
  • 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.
  • 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.
  • The Sociopath: Feels absolutely no empathy for anyone, and shows very little emotion at at all. She merely does what she perceives as the easiest way, not caring if anyone else is happy at all.
  • Telepathy: She can move objects with the power of her third eye.
  • Throw It In: Pretty obviously flubs the line, "I'm Don Juan Cherry Tempo!", but presumably it was too adorable and hilarious to leave out.
  • 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 Jakes 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

  • 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.

  • You Are Better Than You Think You Are: The Ice King constantly encourages her to voice her feelings and break up with the Party God as she wishes to do. At the end of the episode, he also says that she was an inspiration to him as well.

    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

  • The Faceless: 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.
  • 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.

  • What The Funky Fresh, Honey?: Jake gives her one after she manipulated him to pull a heist.

    The MO Factory 

Moseph "Moe" Maestro Giovanni

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!
  • 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

  • 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.
  • Chekhov's Gunman: She was the witch that Ash mentioned selling Hambo to.
  • Eldritch Location: Seems to reside in one.
  • 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.
  • 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.
  • 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 ones life force through their dreams.

  • 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. However the dreams tend to be a bit off to be really effective.
  • 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.

    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.

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.

  • Actor Allusion: Her Weapon of Choice is a knife, much like Isabelle Fuhrman's two most famous roles.
  • 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.
  • 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.

  • Blood Magic: His power comes from his blood and the blood he drains from others. Finn uses this to trick him into killing himself.
  • 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.

  • Body Horror: They are all bloated and deformed, but some are worse than others, such as some with holes in their chests or limbs growing out of their mouths.
  • Nuclear Nasty
  • Really 700 Years Old: They've survived to the present day, and many have escaped from the crater they were buried in.
  • Sickly Green Glow: Their ooze.
  • Was Once a Man: They appear to be mutated humans, given their presence in the city.
    • The appearance of James-like ooze monster seems to confirm this.
  • Zombie Apocalypse: They appear to spread their affliction to those they attack. Including Candy People.

    Cosmic Owl 
Voiced by Jeremy Shada

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.
  • The Other Darrin: Has a more masculine voice than his original voice.
  • 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 of "Farmworld" universe.

    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: [[spoiler:
  • 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.
  • The Lost Lenore: To Simon, although as the Ice King he's not really aware of it. It's ulitmately 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.
  • 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.

    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 (maybe even her in disguise), 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.
  • Theme Initials: Compare "Phlannel Boxingday" with "Princess Bubblegum".

  • 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.
  • Statuesque Stunner: She's 20 feet tall and gorgeous.
