Season 1

    King Worm

A giant worm that absorbs one's life force through their dreams.

Voiced by: Erik Estrada

  • 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.
  • 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.
  • 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 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".
  • The Bus Came Back: Returns in the final season as part of Gumbald's army.
  • Evil Counterpart: To the Ice King. Both want Princess Bubblegum and are antagonists, but the Ice King is a sympathetic Ineffectual Sympathetic Villain while Ricardio is an unsympathetic creep who tries to take her heart out.
  • Evil Is Visceral: He's a living heart, for starters.
  • Evil Sounds Deep: Given who 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 Bubblegum 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.
  • We Will Meet Again: And he made good on his word.
  • Wicked Heart Symbol: He's an actual red heart with a face, arms, and legs. He manipulates Princess Bubblegum with the intention of cutting out her heart.
  • Wrong Genre Savvy: When building his new body, he failed to realize a major flaw: leaving the heart exposed.

    Magic Man

A mysterious, magical trickster 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 everyone in Ooo.

Voiced by: Tom Kenny

  • Ax-Crazy: He's sadistic, psychotic, mentally unstable and likes torturing people as a prank.
  • Bright Is Not Good: Look at him. Especially when shedding his hobo outfit.
  • Brought Down to Normal: As of "You Forgot Your Floaties".
  • Card-Carrying Villain: The guy REALLY likes to let people know he's an incredible jerk, AND PROUD OF IT!
  • 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" it is shown that he used to be a decent guy with a loving wife named Margles until a creature not unlike the Glob brothers named GOLB "took her away", presumably killing her. As shown in "You Forgot Your Floaties", Magic Man created a new "defense system" named M.A.R.G.L.E.S. in the image of his wife, which failed and ended up falling into Olympus Mons, which is what is seen in the "Sons of Mars" production artwork. Doubles as Love Makes You Evil And Crazy.
  • Glass Cannon: He IS very powerful, but the two times Finn and company have actually got their hands on him, it's shown he can't really take a punch as well as the other characters or recover as fast.
  • The Good King: Implied to have become this by the end of "Normal Man".
  • 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.
  • Heel–Face Turn: After losing his magic powers, he decides to atone for all the bad things he did.
  • 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. When he loses his magic powers, though, he loses his jerkassery as well.
  • Karma Houdini: "I win again, just like always!"
    • Averted in "Time Sandwich" when he finally gets what's coming to him when he messes with Jake.
  • 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.
  • Large Ham: "MAGIC MAAAAAAN"
  • Laser-Guided Karma: The first thing Finn and Jake do after returning to Earth from Mars 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.
  • Laughably Evil: Despite being a sadistic psycho, he's very hammy and likes to sing.
  • Meaningful Rename: Calls himself Normal Man after being Brought Down to Normal. He later renames himself King Man after becoming Mars's new king.
  • Morality Chain: His dead wife 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.
  • Reality Warper: Had this ability up until "You Forgot Your Floaties."
  • Sadist: He really enjoys torturing other beings.
  • Sarcasm Mode: Except not always. In "Normal Man" he's shown to be sincere, not that Tiny Manticore buys it.
    Tiny Manticore: Why do you sound so insincere?
    Normal Man: That's just my voice.
  • Stepford Smiler: Until "You Forgot Your Foaties", Magic Man was implied to have deep-seated depression over Margle's death, though he masked it with child-like jerkassery.
  • Straw Nihilist: Up until his Heel–Face Turn, Magic Man accused the heroes (rightfully) that they act like heroes so that they could get what they want, and that still wasn't his lesson.
  • Taking Up the Mantle: While his character and reconciliation as Normal Man is already unexpected, at the near end of the Elements mini-series, has him in possession of Abraham Lincoln's hat and his older brother's staff. Both strongly implying that he worked up his way of atonement to become the new ruler of Mars.
  • Took a Level in Kindness: After losing his magic and regaining his sanity, he became much more empathetic and now rules Mars as a benevolent king. He even reunites Jake with Finn and attempts to help Betty with her issues in "Temple of Mars".
  • Tragic Villain: He has a very tragic reason for his psychotic behavior. See Freudian Excuse for more details.
  • 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.

Season 2

    Hunson Abadeer
"Well, I'm sure not the guy who's gonna suck out your soul."
Also known as the "Lord of Evil". One of the most evil entities in The Land of Ooo, probably second only to the Lich. Currently locked away in the Nightosphere. In season 4, his full name was given as Hunson Abadeer.

Voiced by: Martin Olson

  • Affably Evil: To Finn and Jake in his second appearance, but arguably and surprisingly not Marceline, who he blatantly lies to and manipulates even under the guise of an eccentric but caring father. Granted, he does love and care about her, but is pretty lousy at explaining it.
  • Artifact of Doom: He owns an amulet made of concentrated Chaotic Evil, which gives the wearer a nice suit and transforms him or her into a ruthless Eldritch Abomination.
  • Badass in a Nice Suit: Pilfers souls, rules the Ooo equivalent of the underworld and may rival the Lich himself, all while dressed in a snappy suit and tie. Somewhat invoked, since anyone who wears the amulet gains the suit and tie along with the Chaotic Evil.
  • Blue and Orange Morality: A very odd example (as if this trope wasn't odd enough), but him being a Chaotic Evil Card-Carrying Villain is what makes him have blue and orange morality. Like how he seems to genuinely believe that tricking Marceline into being his heir is the right thing to do, or how he sees nothing wrong with stealing everyone's soul, which in turn is committing genocide.
  • Card-Carrying Villain: He's described himself as "completely evil" with no shame.
  • Chaotic Evil: Invoked. He grew up with it and as seen above, pretty proud of it. Might explain why he kinda sucks at being a parent despite genuinely caring about Marceline.
  • Dissonant Serenity: When he's first introduced, he treats the systemic soul-stealing genocide of Ooo as something he does everyday.
    Hunson: Okay. I'll go. I got business to attend to, anyway. Sucking up all the souls in Ooo.
    Finn: What?!
    Hunson: See you kids later. (Hunson rips open the door and walks out, laughing maniacally)
  • Does This Remind You of Anything?: In his One-Winged Angel form, his face is large and round, with a vertical slit for a mouth.
  • Embarrassing First Name: Jake seems to think so, as he scoffs when he first hears it.
  • Even Evil Has Loved Ones: He really does love his daughter, even if he doesn't show it that much.
  • Evil vs. Evil: In "It Came From The Nightosphere", he's shown to not get along well with the Ice King and Gunther A.K.A Orgalorg, and he seems to have special hatred for the Lich, according to the Adventure Time Encyclopedia.
  • Faux Affably Evil: Like Marceline, he's a playful troll. Unlike Marceline, he makes good on his threats and then some.
  • Fish out of Temporal Water: Possibly, given his reaction when he noticed Marceline turned the family ax into a bass guitar.
    Hunson Abadeer: Did you turn it into some kind of lute?
  • Follow in My Footsteps: Very much wants this for Marceline, to the point where he fools her into taking his Artifact of Doom so that she can have a taste of ruling over the Nightosphere. He mentions being a victim of this himself, although he doesn't seem to mind it at all anymore.
  • Foreshadowing: In "It Came From The Nightosphere", he claims Gunther is by far the most evil thing that he's encountered. While it may seem like a funny bit, he may have been referring to Orgalorg.
  • Greater-Scope Villain: Hunson has almost as much, if not the same amount of bearing on the plot as The Lich. However, the most we ever see of him is roughly an episode and a half. The rest of the time, he's only mentioned.
  • Humanoid Abomination: His default form looks human, but is really a deathless, soul sucking demonic entity. His One-Winged Angel form falls firmly in Eldritch Abomination turf.
  • I Want Grandkids: At the end of "Marcy & Hunson", he asks Marceline "So, when are you gonna have some kids?"
  • Immortality: According to Marceline, he's "deathless" and can't die.
  • Interspecies Romance: Had one with a human woman, and together they had a daughter, Marceline.
  • Knight of Cerebus: One of the earliest examples, albeit being both downplayed and, presumably as of "Daddy's Little Monster", dropped it all together. Though a good amount of his scenes from "It Came From The Nightosphere" is enough to keep a child sleepless.
  • Living Forever Is No Big Deal: He's immortal but doesn't share any of his daughter's angst.
  • Marionette Motion: Apparently a function of the amulet, as he moved normally when he wasn't wearing it.
  • Most Definitely Not a Villain: He pretty much says this to the one of the fluffy people when he's about to steal their soul.
    Fluffy Person: Who the fluff are you?
  • Names to Run Away from Really Fast: It's not mentioned in the episode, but his title is the Lord of Evil.
  • No Name Given: Until "Return to the Nightosphere"
  • Our Demons Are Different: Described by Word of God as more demonic than a vampire.
  • One-Winged Angel: Like his daughter, he can turn into a giant monster. Though his is much more monstrous. Apparently he requires an object of power to do so. She does not.
  • Parental Neglect: He was a rather neglectful father towards Marceline during her childhood, and what officially soured their relationship was when he ate the fries she bought. Still, he really does love her even if he isn't very good at showing it.
  • Pet the Dog: Showing actual compassion towards Marceline.
  • Satan: Okay, it hasn't been confirmed, but considering he's "The Lord of All Evil" who steals your soul, and rules the Nightosphere which is essentially Ooo's version of Hell he probably is.
  • Sealed Evil in a Can: Escaped from the Nightosphere in "It came from The Nightosphere" thanks to Finn, but is banished back by episodes end.
  • Time Abyss: He's at least a thousand years old given he's Marceline's father, and the Adventure Time encyclopedia he wrote in-universe claims he's as old as time.
  • Tranquil Fury: When he notices Marceline turned the family ax into "Some kind of lute", he's visibly annoyed and he holds it against Marceline the entire episode.
  • Troll: Towards Marceline, at least. 50% of the things he does are mainly to make Marceline angry.
  • Unreliable Narrator: While he wrote the Adventure Time Encyclopedia, it makes quite clear at several points that there are things he does not know (such as Simon Petrikov's relationship to his daughter, or his own origins) and that there are assumptions he makes which are incorrect (he is fond of assuming that centuries or eons passed at certain points when other sources would indicate it was probably more like days, years at most).
  • Unknown Rival: Claims to be the Lich's rival in the Adventure Time Encyclopedia. While he is likely one of the only characters with power comparable to him, the Lich doesn't appear to be threatened by him enough to try to kill him like he did with all of his other enemies (though it could be that he may not be able to kill Hunson or even know how to enter the Nightosphere.)
  • Unnamed Parent: He's only known as "Marceline's Dad" until "Return to the Nightosphere".
  • "Well Done, Dad!" Guy: Cares a lot for Marceline's approval, even though he tends to go about it all wrong.
  • Your Soul Is Mine: His MO.

Season 3


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.
  • The Bus Came Back: Returns in the final season as part of Gumbald's army.
  • 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 power user 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, since he has fire powers.
  • 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.
  • Villain Team-Up: With Gumbald.

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".
  • The Bus Came Back: Returns in the final season as part of Gumbald's army.
  • 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 than 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.
  • Hate Sink: In his sole major appearance, he is shown to be a tremendously sexist and abusive boyfriend to Marceline who sold her Hambo to a witch just for his own self-benefit. As a result, any comeuppance he receives is definitely well deserved.
  • 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: He utterly abuses Marceline.
  • Kick the Son of a Bitch: In Betty Simon lays him out with one hit and steals his flying carpet. It's unethical to do towards someone who Simon doesn't know whether he is good or not, but he deserved it regardless. 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 her 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.
  • Villain Team-Up: With Gumbald.


A tiny cat-like assassin that attempts to kill Wildberry Princess in "Jake vs. Me-Mow". She reappears much later in "Angel Face", having become a Bounty Hunter and grown much larger.

Voiced by: Kyla Rae Kowalewski

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.

Season 4

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.
  • The Corruptible: Great going, Jake.
  • Creepy Child: With an uncanny child-like voice coming from a huge monster and unstable psychic powers, she comes off as this.
  • 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.
  • 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 has Telepathy and can make people 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."
  • Telepathy: She can read minds.
  • 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.

Season 5

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.

    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.
  • 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.

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 than the black dots she had before. This allowed for better expressions.
  • 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.
  • Dark Lord on Life Support: She's rendered comatose from the battle in "Something Big", and the Ancient Psychic Tandem War Elephant decides to take care of her. They both reappear in "Flute Spell", probably more than a year later, and Maja hasn't woken up; the Elephant states she may be like that for the rest of her life.
  • Eldritch Location: Her home doesn't obey conventional rules of space.
  • Emotion Eater: 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 needs Bubblegum for her plans. He doesn't listen and nearly killed Peebo, and Maja actually looked quite horrified he was about to go through with it.
  • 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.
  • Knight of Cerebus: Next to The Lich and Ice Queen, she's one of the few threats on the show taken completely seriously. Marceline wasn't willing to confront her without Bubblegum's help and her attack on the Candy Kingdom put the whole kingdom on the defensive, even claiming the life of Root Beer Guy.
  • Manipulative Bitch: 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 than Marceline had to Hambo which is why Maja plans to use the shirt in a spell for "something big!"
  • Not Quite Dead: Gets knocked into a tree after being blasted by the Tandem War Elephant which knocks her into a coma. Ironically said War Elephant is the one who helps her later.
  • Psycho Electro: Abuses her familiar with electricity for little to no reason.
  • The Sociopath: She randomly starts attacking her own familiar when she was in a good mood. Really says something when Marcie's not foolhardy enough to confront Maja on her own and asks Bubblegum to help her.
  • Voice of the Legion: Constantly talks in a reverberating, demonic like tone.
  • Weather Manipulation: She's able to generate wind and lightning.
  • Wicked Witch: Is she ever, and she did it all to get an special shirt.

    Bella Noche

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.
  • Bilingual Bonus: His name is a mix of "Bella", Italian for "beautiful", and "Noche", Spanish for "night". Despite being male, the feminne "Bella" is used rather than the masculine "Bello", as the word being described, "Noche", is itself feminine.
  • 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.

    King of Ooo
Claims to be the king of Ooo. Legally able to perform marriages. Deposed at the end of "The Dark Cloud".

Voiced by: Andy Daly

  • Authority in Name Only: He doesn't seem to wield any real power at all. Until he manages to usurp Princess Bubblegum's place in "Hot Diggity Doom".
  • 100% Adoration Rating: Seems to be the sole reason why people recognize his authority. He says he rules Ooo, and they all believe him. One of Bubblegum's goals is to prove that this is total bullshit.
  • Bizarre Alien Biology: According to Word of God, he's made entirely out of earwax.
    • Confirmed in "The Dark Cloud", when Crunchy throws him into the fireplace and he melts into a yellow-brown blob.
  • The Caligula: When he's become ruler of the Candy Kingdom via an election/coup the whole kingdom goes into chaos because of his total incompetence/inaction of being a ruler. The giant comet in the sky certainly sped things along, but there were signs of dissent even before the comet showed up.
  • Crossdresser: After replacing Bubblegum as the Candy Kingdom ruler, he starts calling himself the "One True Princess", and not only wears dresses and feminine clothes, but also wears Bubblegum's old clothes.
  • Cult: It's implied that he runs one.
  • Everyone Calls Him "Barkeep": Everyone Calls Him the King of Ooo.
  • God-Emperor: Claims that the sun belongs to him.
  • Large Ham: Hammy as only the One True King/Princess of Ooo can be.
  • Laser-Guided Karma: At the end of "Stakes" the Candy People finally turn against him for being a horrible ruler. The Banana Guards rebel against him and then Crunchy throws him into a fire place.
  • Mugging the Monster: It really doesn't get much worse than trying to threaten the Lich into joining your two-bit schemes. Surprisingly, he got away without being killed, "merely" having his mind exposed to nightmarish Things Man Was Not Meant to Know.
  • Narcissist: He fulfills pretty much all of the requirements to count as one. He shows a Lack of Empathy, and Imperviousness to Shame (well, he thought he may be a bad ruler for a moment, but a moment later decided it's all Bubblegum's fault); he's a Consummate Liar and Manipulator; and has a Grandiose Sense of Self-Worth, apparently genuinely believing he should indeed rule all of Ooo.
  • Screw This, I'm Outta Here!: When he's trapped in jail with everybody that stood with him. He breaks out all by himself in a panic, claiming that his paperwork will never hold court.
  • She Is the King: Inverted; at the end of season 6, he becomes the new princess of the Candy Kingdom.
  • Tyrant Takes the Helm: When he becomes princess of the Candy Kingdom in Bubblegum's place, he makes everyone miss PB.
  • Villain with Good Publicity: He's a conman and fraud who only cares about himself and yet everyone in Ooo seems to think he should be in charge, much to PB's chagrin.
  • Would Hurt a Child: Shows no hesitation in "taking care" of Sweet P when he finds out his plan.


A mysterious, yet threatening cosmic entity that bears a striking resemblance to Grob Gob Glob Grod. Turns out he has had followers or such as some point... most notably The Lich.

  • The Anti-God: Implied, since he is an extremely powerful cosmic entity visually contrasted with Grob Gob Glob Grod. Perhaps the biggest example of proof is where The Lich calls himself the "Last Scholar of Golb," meaning the Lich is a follower (if the last one) to GOLB.
  • Eldritch Abomination: It's a malignant cosmic entity, after all.
  • Greater-Scope Villain: Implied to be this in "Whispers", when The Lich calls himself "the last scholar of GOLB".
  • I Shall Return: Grob Gob Glob Grod believes he will attack Mars again, which Magic Man agrees with... at first.
    • Played straight when Betty decides to summon him in order to save Simon and Margles.
  • Overly Long Tongue: It's always hanging out of his mouth.
  • Ret Gone: Presumably what he did to Margles, since not even Prismo could bring her back! When he tried to, all he conjured up was a wastebasket, and he says that something like that has never happened before. It's possible the same thing happened to Finn's life in 'Puhoy'.

Season 6

    Darren the Ancient Sleeper
An ancient being of destruction awakened by Maja in "Something Big"

Voiced by: Alan Oppenheimer

  • Attack Its Weak Point: "His weakness is his brain seed!"
  • Attack of the 50-Foot Whatever: He is easily one of the largest creatures in the show.
  • Beneath the Earth: He emerges from this when Maja summons him.
  • Blood Knight: In his own words, he only understands destruction, and only fights to the death.
  • Death Seeker: His last words are to thank Finn when Finn strikes the blow that kills him.
  • Fish out of Temporal Water: He has no idea what landmarks like the Candy Kingdom are and notes how different the world is since he has been asleep.
  • Flunky Boss: He can summon from a portal flesh-colored regenerating humanoids that hatch from eggs.
  • Friendly Enemy: He's pleased to see the Psychic Tandem War Elephant, although perhaps only because it's good to see a familiar face in a strange world. That familiarity doesn't get in the way of Darren trying to kill the Elephant at all either.
  • When Trees Attack: His mouth even resembles a pine tree.


King of Rats
Voiced by: James Urbaniak

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 Head 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's 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. There's 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: Has red eyes and is a dirty rat.
  • 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.
  • Truth in Television: Rat Kings are a real kind of monster from Medieval times (mostly around the time of the infamous Black Death epidemic, and becoming less frequently reported as time went on) created when poo managed to fuse groups of Rats into a knotty clump by the tail. They were considered horrible omens, and real-life examples of them can be found in British Museums.
  • 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.

Mouse Wizard

Voiced by: Tom Kenny

A mouse 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: The robe he wears is black.
  • 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 thus 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 it's weird but gives him the Ore anyway.

Mouse Knight

Voiced by: Tom Kenny

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

Mouse Thief

Voiced by: Tom Kenny

A mysterious and to-the-point Rat wearing a black outfit that resembles Ninja garb. He protects the Sacred Flame (a blue firefly).

  • Gratuitous Ninja: Possibly, seeing as the other two guardians are more classical in tone (a wizard and a knight).
  • Maybe Magic, Maybe Mundane: Unlike the things the other two Rats were carrying and offering (with the materials being mundane looking), Tthe firefly he offers appears to be magical, glowing a deep blue and actually being used as a forging fire.
  • The Stoic: He is calm and unflappable.

Season 7

The prototype to BMO, who was designed to receive love rather than give it.

Voiced by: Thu Tran, Chuck McCann (when disguised as Moe)

    Dr. Gross
A living, contemporary human from "the island", obsessed with cybernetics and building strange animal hybrids.

Voiced by: Lennon Parham

  • Affably Evil: Her cheer and enthusiasm charm Finn and Jake, until she reveals she's had them unwittingly paralyzed so she can operate on them.
  • Evilutionary Biologist: She earnestly believes that evolution is too slow, and that all the living beings in the world would be so much better if she just could... "level them up".
  • LEGO Genetics: Her second specialty is making hybrids. Animal-animal crosses aren't the least of it: among other things, she's somehow managed to splice a flan pudding with the common fly.
  • The Reveal: She's a genuine present-day human, and an exile from an island full of other surviving humans.
  • Slowly Slipping Into Evil: She used to be in charge of training Seekers for Founders Island, but slowly became obsessed with making hybrids, and ultimately (accidentally) unleashed a plague that wiped out nearly two-thirds of the island's population. We don't learn what became of her after that, but by the time we meet her in "Preboot", she's already a full-blown supervillain.
  • Transhuman: Describes herself as Human+, a real-world transhumanist term. According to her, the next logical step from glasses and artificial hearts is scissor hands and telescoping spider legs.
  • Transhuman Treachery: Her ultimate plan is to build a hybrid army, return to the island, and forcibly convert everyone there into cyborgs.
  • Unwitting Instigator of Doom: She accidentally created a catastrophic plague that killed lots of people and ended up turning Minerva Campbell into the kind of being that she is nowadays. Although she doesn't seem to have learned much from her mistake.

The Vamps

    General Tropes 
The main antagonists of the "Stakes" mini series. Sometime after the Mushroom Wars they preyed upon the last of the human survivors. Marceline opposed them to protect her newfound friends. Though in the process due to her soul sucking powers, gained their abilities as a result after killing them. In the final battle against the king, he bit her and changed her into part vampire to ensure his kind live on.

In General

  • Divided We Fall: When they were revived, Empress, Hierophant and Moon disagreed with the Vampire King on how to continue their kingdom and went their separate ways.
  • Five-Bad Band:
    • The Leader: The Vampire King
    • The Dragon: The Moon, who is fought before the Vampire King
    • The Brute: The Hierophant, whose alternate form is phisycaly strong
    • The Evil Genius: The Empress, who has ability to mind control
    • The Dark Chick: The Fool, who is the silliest and the weakest of them all.
  • Last of His Kind: Marceline had all but wiped them out so in turn, the Vampire King turned her into a vampire to make sure his kind still lived on.
  • Our Vampires Are Different: Each have their own unique abilities and features.
  • Sealed Inside a Person-Shaped Can: All of their vampire essence is contained within Marceline after she defeated them. So when Bubblegum used her machine to turn her back into a regular half-human demon, the black goop that was her vampire essence allowed them to escape and revive, kicking off the mini-series.
  • Tarot Motifs: Their names reference four of the Major Arcana. They're all meaningful in some way to their characterization and their respective cards' inverted positions can be related to their downfall.
    • The Empress represents beauty, femininity and abundance; she is the most traditionally feminine of the group, the most irate about the decadent standards they used to have and is regarded as highly beautiful by Ice King. Inverted it represents a dependence on others, something exemplified by her MO of enthralling people to serve her. Ultimately she is defeated when the I Work Alone Marceline receives some much needed assistance from her friends after the Empress abandons Ice King.
    • The Fool represents innocence, spontaneity, and free-spiritedness; The Fool himself acts like an incautious, carefree child. The reverse position can reference a disregard to obvious dangers, befitting the Fool's Too Dumb to Live personality. Marceline herself acts very foolhardy when she elects to go after all the vampires by herself, starting with the Vampire King first before being distracted with the threat of the Empress against Ice King.
    • The Hierophant represents institutional wisdom, religious teaching, and traditional belief systems; this one is the most traditional vampire, beholden to the old ways such as Must Be Invited. Jake meanwhile completely relapses into his intense vampire phobia. In a reversed position it indicates a downfall by an inability to adapt, with the Hierophant being very slow and irate about technology and ultimately destroyed by his upholding to old vampire standards.
    • The Moon represents dreams, deception, and illusions; she is found sleeping, looking deceptively harmless with some ambiguity regarding how much of her abilities are being deceptively hidden, poetically described or literally explained. There is a lot of dreaming by Marceline in her episode. Reversed it represents confusion, regarding the Poor Communication Kills that also occurs in her episode, and everyone's baffled fear regarding her.
    • The Vampire King at first seems to buck this trend, but throughout the series could be seen as representing several Major Arcana himself. Pre-death he could be seen as The Emperor, as the king of the vampires, but need to keep the vampire race from dying out allowed him to willingly sacrifice himself to Marceline to turn her into a vampire. After being revived, he mentioned the Wheel of Fortune by name (and Word of God has insinuated that is the king's Arcana, at least during the adventure), he had the incredible good luck to be revived, and like the wheel is reliving the same cycle looking for a turning point to escape it, however due to incredibly bad fortune (the bucket with his vampire goop being spilled out) his dark essence is released into the world. Even post-devampirism the king now transformed back into a lion could be seen as The Strength, through personal strength, courage, and patience he has been cured of the vampire curse, and although he doesn't die, due to his weakness and lack of self-discipline from being returned to a normal lion, he offers no assistance against the dark cloud that is the physical manifestation of that curse.
  • You Kill It, You Bought It: Sort of; when Marcy killed them she sucked in their souls which granted her their abilities. Though it's implied if she didn't, they would reform eventually. In a more straightforward manner, killing the Vampire King is what made her the Vampire Queen.

    The Vampire King
Voiced by: Billy Brown

  • Arch-Enemy: To Marceline, even called such in the episode description.
  • Berserk Button: The only time he really gets mad is when the Hierophant suggests they go back to the old-fashioned way. He almost crushes him with telekinesis as he points out their old way of doing things lead to their extinction.
  • Defector from Decadence: Part of the reason he lets his group disband. Their old way of doing things as a horde lead to their extinction. He's partially irritated at the Empress' suggestion they get back to their old standards like blood with gold-flecks in it, as it didn't add any flavor.
  • Humble Goal: Before coming Back from the Dead he just seems concerned with making sure his species would continue to exist. He was fine with dying so long as Marceline would be the last vampire in his place.
  • King of Beasts: A lion and Vampire Monarch.
  • Large and in Charge: Largest vampire in the group.
  • Man of Wealth and Taste: Wears a fine looking white suit.
  • Making a Splash: At one point he manipulates water.
  • Mind over Matter: Demonstrates telekinetic abilities.
  • Mix-and-Match Critters: A large vampire with the head of a lion, lizard-like claws for hands, and bird talons for feet.
  • Not So Above It All: Despite being a stoic and imposing Vampire Monarch who everyone sees as the Big Bad, he has a few silly moments such as his unflinching Helium Speech after being kicked in the groin and when his grand speech leads to him splashing around in water wearing only briefs. In the case of the latter, he becomes so consumed Chewing the Scenery that Marceline has to shout at him and remind him what they were talking about beforehand.
  • Odd Name Out: The Vampire King is the only vampire not directly named after a Tarot card, though his name is analogous to The Emperor, while his slightly more monstrous design and desire to escape the chains of fate and the endless cycle of fighting, death and rebirth that comes from being a vampire evokes The Devil card. His grandiose speech also name drops Wheel of Fortune and The Chariot. His true form as a lion may also evoke The Strength card (which is typically depicted as a woman and a lion) not to mention as the king he is the strongest of the vampires.
  • Pocket Dimension: Through unknown means created an invisible space that filters out sunlight.
  • Raising the Steaks: He is a lion that was turned into a vampire.
  • Reasonable Authority Figure: Unlike most vampire villains he's a very calm and reasonable person. He spends his fights with Marceline trying to sincerely reason with her and exhibits none of the sadism typical of vampire big bads. He isn't even a Bad Boss, simply letting his group disband on their own separate ways when their differences prove irreconcilable.
  • Stock Underwear: He is shown to wear briefs.
  • Token Good Teammate: The Vampire King is the only vampire before Marceline who is, if not outright good, at least very thoughtful and pragmatic. He only considers drinking blood as a means of subsistence, not something to indulge in, and doesn't speak condescendingly of their victims. Once he discovers there's a way to stop being a vampire, he decides to use it.
  • Uplifted Animal: He was apparently a non-sapient animal before becoming a vampire. And appears to go back when he stops being one.
  • Vampire Monarch: The Vampire King.
  • Vegetarian Vampire: After resurrection, he elects to eat only animals like everyone else.
  • Villain Teleportation: Disappears and reappears elsewhere.

    The Empress

Voiced by: Rebecca Romijn

  • All-Encompassing Mantle: Has a veil that covers her eyes until she needs to hypnotize someone.
  • Hypnotic Eyes: Has these when she pulls back her veil.
  • Invisibility: One of the powers she possesses and the main power Marceline gains from her when she's defeated.
  • You Have Failed Me: Once she realizes Ice King wasn't really controlled by her powers, she pretty much disowned him as she found he was too stupid for a servant.

    The Fool

Voiced by: Ron Funches

  • Does Not Like Shoes: Completely barefoot.
  • Flight: His main power and what Marceline gains from him when he's defeated. He spends all his time off the ground.
  • The Imp: He's practically non-malicious. All he does is float around cracking jokes, treating everything like a game.
  • Too Dumb to Live: Not exactly one for self preservation. Both times, he's the first one to get staked because he doesn't bother to protect himself.
  • Undying Loyalty: The only one not to abandon the Vampire King when the others disbanded.

    The Hierophant
Voiced by: Paul Williams

    The Moon
Voiced by: Beau Billingslea

  • Evil Sounds Deep: When she finally does speak, it's a very deep demonic voice.
  • Lunacy: Her name aside she implies that her power is connected to the moon but it's ambiguous if she was being literal or poetic. There is some credence to in vampire lore (the title character of The Vampyre was another Daywalking Vampire who was simply stronger in moonlight) but it's pretty obscure.
  • Good Thing You Can Heal: Her main power and what Marceline gains from her when she's defeated, she has very strong healing. The Fool refers to her as a "backwards egg" because a simple crash on the head completely caves it in before her healing restores her. Even dragging her into the sunlight doesn't do anything.
  • Just Toying with Them: Finn notices when she's chasing after Jake and him that she doesn't really seem to be picking up speed and comes to the conclusion she's just messing with them.
  • Nigh-Invulnerability: Completely hard to kill, Finn and Jake stake her several times while she's sleeping and even drag her out into the sunlight. Nothing works. She only goes down because Peppermint Butler manages to incapacitate her with a tree trunk-sized stake to the back; Marceline actually absorbs her while she's still alive.
  • Refuge in Audacity: Unlocks a safe just by repeatedly yelling the word "pigs".
  • Stringy-Haired Ghost Girl: A dead ringer for one, except with a dark tunic instead of a white kimono.
  • The Quiet One: Rarely utters a word while with her company. It isn't until she's chasing Finn and Jake that she finally speaks.
  • Unusual Ears: A single bat-like one in the middle of her forehead. Marceline described her as having "a head like a garden trowel".
  • Who's on First?: PB instructs them to "[guys] take her back" to Peppermint Butler's poison lab but they mishear it as "stake her back" which is completely ineffectual. Turns out that Peppermint Butler staking her back with a large enough stake was enough to immobilize so Marceline could suck up her essence.

Season 9

     Gumbald (SPOILERS) 


PB's mysterious uncle who reappears in Season 9.

Voiced by: Fred Melamed, Mark Hamill (as Punchy)

  • Artificial Family Member: He isn't really Princess Bubblegum's uncle—she created him when she tried to make a family.
  • Big Bad: After the Lich was killed (again) in "Whispers", he's left as the only recurring antagonist.
  • The Dog Was the Mastermind: Gumbald was a relative of PB mentioned way back in the season two episode "Susan Strong". Seven seasons later, it turns out he was both a villain and the original form of Punchy the Punch Bowl, an extra that's been around since the first season.
  • Evil Cannot Comprehend Good: When PB figures out he coated Finn in "dumb powder" to try and neutralize her, he shows that he believes rendering her harmless is the same thing as making peace.
  • Evil Counterpart: Just as smart as PB but without any compassion or empathy for others.
  • Evil Plan: Take out Finn so Bubblegum will be defenseless, so he can take over her kingdom.
  • Evil Uncle: He's Princess Bubblegum's uncle (though not literally), and wants to kill both her and Finn.
  • Greed: Obsessed with making money, originally. Now he wants to destroy his "niece" and Finn.
  • Hoist by His Own Petard: He was transformed into Punchy the Punch Bowl by his own dumb juice.
  • Hypocrite Has a Point: Though he does the same thing much more flagrantly, Gumbald is right that PB wanted her "family" to go along with her plans for the Candy Kingdom, despite claims that she wanted them to be equals. Sure enough, all the candy people PB makes after that point are just as stupid and obedient as Gumbald tried to make Princess Bubblegum. However, Bubblegum made them not way because she genuinely thought they'd be more happier that way ... and they are still capable of free will, not mindless slaves. They did eventually lose patience with PB and they elected the King of Ooo in her place.
  • It's All About Me: All he cares about is himself. He used his dumb juice on his wife and son just so he wouldn't have to share any money.
  • Phlebotinum-Induced Stupidity: He creates "dumb juice" to turn his family into obedient idiots. It worked on Chicle and Lolly, but then backfired on him.
  • Psychopathic Manchild: Not as blatant as Lemongrab, but in spite of his intelligence, he's extremely short-sighted and selfish.
  • Unexplained Recovery: He was Punchy the Punch Bowl for about 800 years before he was somehow transformed back into his old self. It's not until "Seventeen" that it's explained to be a result of the World-Healing Wave unleashed at the end of Elements.
  • Walking Spoiler: Oh boy. The biggest — he was actually Punchy the Punch Bowl for the first 8 seasons. He was transformed by some of his own dumb juice.
  • Villain Team-Up: Recruits almost every single antagonist of the series (and the Ice King) to fight alongside him and Fern during the war between the Candy Kingdom and Gumbaldia.
