Finn the Human
" I'll slay anything that's evil. That's my deal."
The intrepid human boy. Hyperactive with a love of adventure and good deeds. That thing on his head is actually a hat
. Originally 12 years old, he gets older each year.
Voiced by: Zach Shada in the 2006 pilot, Jeremy Shada in the series
Finn the Human provides examples of the following Tropes:
- Adorkable: Especially when crushing on Princess Bubblegum and later Flame Princess.
- Artificial Limbs: Alternate depictions of Finn pretty much always show his right arm to be a crude prosthetic, such as his dream of himself as an adult. Also applies in the Farmverse.
- Even applies to his past life as Shoko.
- Alternate Self: In the "Farmworld", he gets the full name "Finn Mertens".
- Auto-Tune: He's able to switch this effect on and off for his actual singing voice after he swallows a tiny computer immediately prior to "The Jiggler"
- Awesome Backpack: His big, green, circular backpack.
- Badass Adorable: He skinned a polar bear for his hat as a baby. Do the math.
- Badass Normal: When he's not borrowing wizard powers from talking tadpoles or summoning ice shurikens. He beat the Lich with a sweater. Albeit not at full strength.
- Berserk Button:
- Unsurprisingly, he doesn't react well to Jake or Princess Bubblegum being threatened.
- In "Evicted", Marceline kind of killed Jake for a minute. Finn's reaction was... not pretty.◊
- In "To Cut a Woman's Hair", the witch merely uses Jake as a cushion (albeit in the context of Finn's requiring someone to be in "danger" in order to help her), and Finn charges.
- Finn doesn't seem to take it well when someone even tries to come between his and Jake's friendship. Just ask Tiffany.
- He freaked out when the Jiggler mother attacked her baby rather than take it back. Given that his first memory is being alone in the woods as a baby, it's understandable that he might have some issues with this.
"Mamas are supposed to love babies! THEY'RE SUPPOSED TO LOVE BABIES!"
- When Jake is transformed into a Lumpy Space guy.
"I f-f-f... AAAAHHHHHH I'LL KILL YOU LUMPY SPAAACE!"
- When his picture frame of Bubblegum is set on fire after he spent hours crying over it, he snarls:
"WHO LIT THAT FIRE? I'LL KILL YOUUU!"
- Beware the Nice Ones: As nice a guy as he is, it would be unwise to get on his bad side.
- Blood Knight: He may be in it mostly to slay evil, but there's no denying that he really likes fighting for its own sake ("If you're an evil witch, I will punch you for FUN!") When he wins the Fight King's "favor," he really hams it up.
- Bodyguard Crush: On Princess Bubblegum.
- Book Dumb: See Idiot Hero.
- British Teeth: Due to biting rocks and trees.
- Broken Ace: Multiple times, but he always manages to pick himself back up.
- Character Development: He's getting more aware when it comes to romance, and he's also getting less and less silly and more mature as the show goes on. More complex aspects of his personality are developed slowly, so he often comes off as a Static Character. The show has celebrated his 13th birthday in what is likely a case of Real Life Writes the Plot since Jeremy Shada's voice has noticeably deepened.
- Chick Magnet: So far, lots of princesses want to give Finn a peck on the cheek.
- Chronic Hero Syndrome: In one episode, he displays this, the reason being when he was a baby, he was left alone in the forest and nobody came to help him. It's downplayed in general; he takes his hero work as a calling in life, but tries not to step on anyone's toes.
- Collector of the Strange: In "The Jiggler" it's revealed he has a glass eye collection. It's never mentioned again.
- Combat Sadomasochist: The kid jumped into a volcano for fun. You finish the math.
- Compressed Hair: Hair that would probably go down to his feet, until he cut it off.
- The Conscience: To counteract his other friends' occasional amoral tendencies.
Look at all this grave booty! CHA-CHING! Finn:
Jake! You LOOTED?
, man! Jake:
Oh... I didn't know it was wrong... Finn: (sigh)
Come on, let's put all of this back. Jake:
of it?! Finn:
- Cool Sword: His first one has a blade of gold. The second has an interesting, woody handle and an Absurdly Sharp Blade.
- As of "Dad's Dungeon", he gets a sword made out of a demon's blood.
- Crazy Jealous Guy: He gets extremely jealous when someone comes in the way of him and Princess Bubblegum or Jake.
- Creepy Child: From snuggling a piece of Princess Bubblegum's hair to watching Jake sleep and taking pictures, Finn can be a disturbing child at times.
- Dating Catwoman: Flame Princess is quickly revealed to be evil. Finn develops a crush on her after she attacks him.
- Determinator: His very first appearance has an amusing double-subversion. Finn is told to believe in himself in order to escape his prison of ice; Finn refuses, but then breaks out through sheer willpower. In the series proper, he soldiers past numerous injuries, breaks out of the Lich's mind control, literally ignores two broken legs to save the day(s).
- Did You Just Punch Out Cthulhu?: He frequently goes there. For instance, in "Freak City" he, in a fit of rage, decides to beat up Life. In another episode he attacks a fourth-dimensional black-hole type construct, and destroys it.
- Distaff Counterpart: Fionna.
- Easy Amnesia/Laser-Guided Amnesia: Finn can put frightening memories in his "vault". What's disturbing is that he does it so casually...
Finn: That one's going in the vault. Aaaaaaand... it's gone.
- Once Finn opens the vault just a crack, he's apparently easily able to discover his past lives.
- The First Cut Is the Deepest: Princess Bubblegum.
- For Great Justice: His reasoning for why he fights evil.
- For Happiness: When he and Jake aren't busy fighting evil, they're just trying to have a good time.
- Fetish: As the teenage boy hormones kick in, it's been firmly established that he gets off on violence. Not dealing with this very well is what destroys his relationship with Flame Princess.
- Freudian Excuse: Finn helps people because of a traumatic experience as a baby.
- By extension this seems to have given him abandonment issues.
- Genre Savvy: To the point of predicting every single part of the Fight King's trap after nothing more than a few lines from him in "Morituri Te Salutamus".
- Was also smart enough to invoke Unspoken Plan Guarantee by not telling even Jake about his overall plan to trick the Fight King into giving him his Soul Jar so he could destroy it.
- Gonk: His Alternate Self from Farmworld:
Jake: Man, Alternate Wish-World Finn is mad uglies!
- Growing Up Sucks: After his breaking up with Flame Princess Finn started to feel things became more complicated as he was growing up. wishing to have things be like they were before.
- Hair of Gold, Heart of Gold: Although his hair color was only Word Of God, it's since been seen. And it is glorious◊. He has the associated purity.
- Happily Adopted: By Jake's family.
- The Heart: He's the only one who can get Bubblegum and Marceline to stick together; in 'What Was Missing', it's clear that their attempt to get through the Door Lord's door would have fallen apart fairly easily without his influence.
- Heartbroken Badass: His love life hasn't exactly been kind to him.
- The Hero: In general, and by reputation. He's basically a freelance knight, with most of his work coming from the Candy Kingdom (due to proximity), though he and Jake also specialize in dealing with the Ice King.
- Heroes Fight Barehanded: Despite owning at least two swords, Finn usually fights with his bare hands.
- Heroes Prefer Swords: Though he uses Good Old Fisticuffs much more and an ax at least once.
- Heroes Want Redheads: His crush on the Fiery Redhead Princess Flame.
- Heroic BSOD: He goes through a (hilariously brief) one every time somebody reminds him that he's almost certainly the last human.
- Heroic Willpower: Goes hand-in-hand with his many Determinator feats.
- Hidden Depths: Lightly hinted at a few times. In particular, he may hide a desire for civilized life, as well as trauma stemming from his Parental Abandonment. He rarely if ever dwells on such things, however.
- Hormone-Addled Teenager: As of recent. Somewhat justified considering he's a fourteen year old boy.
- Hotblooded: From the "Hero Boy Named Finn" song:
Finn: And I'm not gonna be cool... 'cause I'm pipin' ho-oooooot!
- Hulking Out: Finn, when something happens to Jake. Then he's talked down by Jake and calms down.
- I Am Not Weasel: Flame Princess comes to the conclusion that he must be a Water Elemental due to him crying each time she's seen him and him repeatedly hurting her without realizing it. Also, the squirrel from "Up a Tree" mistakes him for a chipmunk.
- I Can Change My Beloved: After the Flame King explicitly explains that his daughter, like everyone else in his kingdom, is evil, Finn makes influencing her to good his goal. (It definitely helps that she's on board with it.)
- An Ice Person: After putting on the Ice King's crown in the Farmworld universe.
- Idiot Hero:
- Which makes it that much more interesting when his brain works perfectly, like in "Morituri te Salutamus".
- As shown in "The New Frontier", Finn occasionally forgets how the sun works, and is seemingly floored when Jake re-explains it to him.
- In "In Your Footsteps", he freely gives away the Enchiridion, a "hero's handbook" he got dozens of episodes ago, because he's mostly used it for sitting on. It falls into the Lich's hands.
- He seems to be growing out of it though. While he's still dumb, he's quite a bit wiser nowadays.
- I Gave My Word: Finn basically lives by this. Especially after the events of "Slumber Party Panic".
- I'll Kill You!: A couple of times. See Berserk Button.
- Important Haircut: To save Jake from eternity in a witch's butt. Since then he seems to be letting it grow out again.
- Improbable Aiming Skills: With paper airplanes. Pity that he overestimates his own ability in this area.
- Incorruptible Pure Pureness: To the extent that he tries to beat his purity into others. Even his just born sphinx clone was automatic good and did a Heroic Sacrifice to stop his evil "sister" Goliad.
- The Lich uses this against him to open up a portal to the multiverse by a means Finn thought would prevent it.
- Inter-Class Romance: His two love interests are princesses.
- Interspecies Romance: So far he's crushed on a candy person (princess) and a girl made of flames. And in "Puhoy" he even married and had two children with a pillow-girl.
- Of course, being the last human he doesn't have a lot of choice in avoiding this.
- Jerkass Ball: In 'Jake Suit he doesn't care that Jake gets hurt when he wears him as armour and tells him to toughen up then at the end of the episode he wears the 'Jake Suit' and jumps down a volcano hurting Jake and himself. And more recent as of "Frost and Fire" and "Too Old", the former of which has him ruining his relationship with Flame Princess, and the latter lying to Jake in hopes of getting alone time with PB. (It doesn't work.)
- FIRMLY grasps the Jerkass Ball in Frost and Fire to the point that Flame Princess breaks up with him.
- Keet: Finn is hyperactive, joyful, and sometimes surprisingly tender-hearted, when he's not beating his enemies to a bloody pulp.
- Kid Hero: 15 years old and growing.
- Large Ham: Not just large, massive. He competes with a World of Ham and manages the impressive feat of being one of, if not the hammiest ham in the land of Ooo.
- Last of His Kind: According to Word Of God, Finn thinks he's one of these. We certainly haven't been shown another normal human yet. We thought we did, but they turned out to be Fish People.
- Whether or not Susan is human is left up in the air, as she never takes off her hat.
- In "Beautopia", it's more or less confirmed that she's human.
- Another long time member of the cast at least used to be human.
- It's now subverted as BMO's creator, Moe, is still alive and human (well, his skin is).
- Lightning Bruiser: Finn has been shown to excel in all types of combat within the series, plus he is quick to his feet & able to take a HUGE beating. Pretty much, he just destroys any foe that stands in his way.
- Limited Wardrobe: Invoked a couple of times. For example, a plot point in "BMO Noir" and "Princess Potluck"note is that he seems to only have one pair of socks, and in "Little Dude" he has to go slay (another!) evil bear if he wants a replacement hat.
- Love at First Punch: Finn developed his crush on Flame Princess after she smacked him in the face with her (burning) hand and nearly destroyed his house with her fire powers.
- Love Hurts: Both princesses have caused him no small amount of emotional (and physical) hurt.
- Love Makes You Dumb: He tells Flame Princess she has this effect on him.
Finn: When I look at you, my brain gets all... stupid!
- Made of Iron: The kid has survived battles against multitudes of monsters, cosmic horrors and falling into a volcano, the last of which he did for fun.
- Meaningful Name: "Finn" means "fair-haired." He's blond.
- Moral Dissonance: Has shown up a couple of times mid-season five where Finn has gone against his usual pure and "righteous" code for his own gain. It hasn't gone well for him.
- Motive Decay: For at least one episode. In "Too Old," Finn focuses on flirting with Princess Bubblegum instead of focusing on the diplomatic mission, rescuing Lemonhope, and basically being a hero.
- Muggle Best Friend/Morality Pet to anything that isn't completely evil. Shades towards All-Loving Hero.
- Princess Bubblegum tends to show off her creations to him. (She's just as likely to use her own half-baked creation, but perhaps this is just safety testing.)
- Marceline trusted only Finn with her Fries song.
- Heck even the Ice King seeks Finn out when he wants somebody to chat to.
- Mundane Made Awesome - "ALGEBRAIC!"
- Nice Guy: Probably one of the nicest members of the cast.
- Nice Hat: He apparently skinned a bear to make it. As a baby.
Finn: My... hat... is... AWESOME!!!
- Nice Job Breaking It, Hero: Season 4 Finale. Congratulations, Finn. You've single-handedly released the Lich into The Multiverse. And in "Frost & Fire", his obsession to see Flame Princess and Ice King fighting almost causes Ice King's death and the destruction of Ice Kingdom, and also ends hurting Flame Princess feelings, leading to their breakup at the end of the episode. When the Ice King tells you that you blew it, you know you really blew it.
- The Noseless
- Not Allowed to Grow Up: Averted. In fact, he grows up in real-time! (He ages every year, according to Word Of God.) Though he's only had one on-screen birthday from 12 to 13, his Twitter profile identifies him as 14 as of 11/2012.
- The Paragon: In "Freak City" Finn refuses to let any of the freaks lay down and let life kick them around. So instead, Finn kicks them around until they decide to stand up for themselves.
- Parental Abandonment: Not only was had he lost his birth-parents from babyhood, it is heavily implied that his foster-parents, Joshua and Margaret, are also dead, leaving him with only Jake at 12.
- Parenthetical Swearing: He loves this trope.
"What the jug is that?
"Dump that mess!''
- Pint-Sized Powerhouse: Despite being just a boy, he's a full-fledged adventurer who can hold his own in most fights. He's even been known to put the hurt on beings many times his size and experience, especially when properly motivated.
- Pretty Boy: His Gaia Online Alternate Universe self is this in the Adventure Time themed chance item, while his FusionFall self is a winsome Gonk.
- Psychic Static: Even mentally he's a small erratic target. Especially mentally.
- Pungeon Master: He loves to drop puns.
"I'm weddy for the wedding!"
(pushing a zombie into the ground) "You're grounded, mister!"
(blasting a pig with ice cream) "FREEZE TO MEET YOU!!"
- Raised by Wolves: Well, they were magic talking dogs, and they were pretty much as intelligent as humans. "Boom Boom Mountain" reveals Finn was orphaned as a baby and taken in by Jake's parents. Jake is pretty much his big brother.
- Rapunzel Hair: Though he lost it soon after it was revealed.
- Real Men Wear Pink: For example when he spends the night with the Ice King in "Thank You".
- Reincarnation: In "The Vault", Finn is revealed to have lived several past lives, including the ghost woman haunting him, who was a mercenary named Shoko.
- Rhymes on a Dime: Has made up songs on the spot on several occasions, just for the heck of it. With his singing voice the effect is pretty rad.
- Samaritan Syndrome:
- In "Memories of Boom-Boom Mountain", Finn reveals his underlying drive to help everyone and everything with their problems because when he was a baby, he once went 'boom-boom' on a leaf and got stuck to it, and went unaided for hours until Jake's parents found him (and eventually adopted him). Finn helps people because someone helped him once.
- Subverted on at least one occasion, where he mentions that he probably should help the Ice King, but he's too inexperienced and has no clue how to deal with the Ice King's issues. So he beats him up.
- Screaming Warrior: Goes into this anytime he's in a fight.
- She Is Not My Girlfriend: Regarding Princess Bubblegum. Jake even calls her his ex at one point.
- Shipper on Deck: In "All The Little People", Finn finds sentient miniature AT characters and puts them all in crazy pairings. Even before this, he tells Jake that he thinks BMO and Ice King might make a good couple.
- Singing Voice Dissonance: Throughout the series, he sings with an auto-tuned voice that supposedly comes from a tiny computer he swallowed at some earlier point. Subverted in 'What Was Missing', where he sings a heartfelt song to (and about) his True Companions Jake, Bubblegum and Marceline.
- The Sleepless: Invokes it at least with the line "Justice never sleeps!" He does sleep regularly.
- Star-Crossed Lovers: With Princess Flame as of "Hot to the Touch". Finn cannot touch Flame Princess without getting hurt.
- Summon Magic: It takes him many hours to summon his spirit animals in "Still", but at least he gets a whole bunch of them and they're rather badass, for their species. Hunson is quicker to summon, but his allegiance remains in doubt.
- Sure, Why Not?: His 13th birthday episode first aired, coincidentally, on Pi Day (March 14, 2011) which first Fanon and later Word Of God made his birthday.
- Tagalong Kid: In "What was Missing", Finn said that he thought this trope was the way the others saw him. An odd example, as he's arguably more proactive and competent than nearly everyone else in Ooo most of the time.
Finn: Do you look down on me cuz I'm younger?
- 10-Minute Retirement: In "Freak City", Finn goes through one of these after getting turned into a foot, during which he memorably goes into Auto-Tuned song. Though it's more thirty seconds than ten minutes. The later episode "Davey" is built around this also with him developing a split personality.
- Token Human: Occasionally a plot point.
- True Companions: With Jake, emphasized by both family bonds and loyalty, and with Bubblegum to a slightly lesser extent. As characterization has developed, he may possibly also have this with Marceline, given how highly she regards friendship. All of them take some steps towards becoming True Companions in "What was Missing", though with Jake being the Wild Card, and Marceline and PB not getting along very well, it takes some considerable effort on his part.
- Unstoppable Rage: See Berserk Button above.
- Weaksauce Weakness: Finn's fear of the ocean. (He has a few others, but they are rare or unlikely to occur.)
- We Are as Mayflies: Inverted - it's strongly implied that his canine adoptive family ages in dog years.
- "Well Done, Son" Guy: He can only carry on if he knows his dad cares for him, as seen in "Dad's Dungeon".
- What the Hell, Hero?: Delivers one to Bubblegum in "What Have You Done?" when she has the Ice King imprisoned despite him not doing anything wrong. Turns out she intended to beat pained cries out of him. True, it was to cure the Candy Kingdom of a plague he accidentally started, but it's still a bad thing to do. Finn and Jake call her out on it and she does seem to get a What Have I Done moment as a result.
- Also in Frost & Fire where Finn tricks Flame Princess and Ice King into fighting using her own private issues against her. Ice King even flat out states to Finn "You blew it."
- When All You Have Is a Hammer: His response to the black hole he created?
: You blew it, Finn! With this! [Shows bubble-blowing device] Finn
: Then I'll kill it with this
- Why Did It Have to Be Snakes?: He's terrified of the ocean and only the ocean—not rivers, lakes, or puddles. He is also afraid of the body of water in question whether he consciously knows it's the ocean or not.
- With Great Power Comes Great Insanity: After putting on the Glasses of Nerdicon.
- Any time he gets any sort of artifact of power it will quickly be taken away from him. (Wizard, Daddy's Little Monster, etc.)
- In the season five premiere, when he uses the Ice King's crown in the Farmworld.
- Would Hit a Girl: Finn would hit anything. Except a princess. He's very uncomfortable punching princesses.
- Zany Scheme: One day he may be the master of these, in the meantime he gets egg on his face (or Marceline's kitchen floor). Simply lifting Treetrunks is insufficient. Instead he has to out on thick layers of makeup first. And so on.
Jake the Dog
Finn's chummy, size-shifting bulldog friend (not pet) and foster-brother. He is more laid back than Finn, but also enjoys adventure. He sometimes gives Finn brotherly advice, but it is not often helpful.
- Overprotective Dad: At first with his and Lady's children, strictly adhering to the manual his mom left for him. He stops when he realizes that, like he was as a kid, his children can take care of themselves.
- Pals with Jesus: While Prismo falls more into Reality Warper than Physical God, the trope sorta applies. He befriends both Prismo and Cosmic Owl by the end of the Season 5 premiere episode. It benefits Jake greatly because Prismo goes out of his way to help Jake word out his wish to screw the Lich over. He even invites Jake to drop by any time.
- Papa Wolf: He often acts like a father figure to Finn. He is usually very lazy and indifferent about most things, but when something serious happens to his younger companion, you better not be around.
- His "The Reason You Suck" Speech he made to Princess Bubblegum in "Burning Low":
(...) YOU HEARTLESS MONSTER! Do you have any idea how much he's CRIED OVER YOU?! (...)
** He later tries to be this to his own children, but he ends up veering into Overprotective Dad
- Reality Warper: Using his imagination. Though only for one episode, and for no explained reason.
- Reformed Criminal: He once ran a gang of bank robbers who were quite successful when he was younger, but he left the life behind. He pulls his gang back together in "One Last Job."
- Rhymes on a Dime: He seems to enjoy a good rhyme. Forceed Finn to communicate via rhyme during "Ocean of Fear"
- Rubber Dog: Has stretching powers that could give Mr. Fantastic a run for his money.
- Running on All Fours: Well, yeah, he's a dog. He usually goes around on his hind legs, but he'll go on all fours if he needs to go fast or if Finn is riding him.
- Serious Business: Whenever he makes sandwiches, burritos... well, anything with lots of ingredients, let's just say he becomes attached to his creations like an overprotective mom.
- Shipper on Deck: Or at least loves to needle Finn about his crush on Princess Bubblegum. He also looked very pleased when Finn and Flame Princess hugged... And he also got quite excited when he thought PB was jealous. Most likely Jake approves of any sort of relationship Finn has with a girl, so long as Finn's happy with it.
- The Slacker: He'd rather go with the flow sometimes.
- Sore Loser: Well, at least when it comes to Card Wars.
- Spanner in the Works: Jake has trouble sticking to any of Finn's plans.
- Spider-Sense: Jake has the ability to sense when Finn is about to cry.
- Story Breaker Power: Many Finn-centric episodes would actually be solved in two seconds by having Jake around, so his Brilliant, but Lazy personality is used to allow Finn to fly solo and rely on his wits instead, and explain why Jake isn't there (to the point where a couple of episodes actually have Jake shrink down and ride Finn so he can see how it all turns out.)
- Super Strength: Jake seems to have this as a Required Secondary Power to his stretchy powers.
- Trademark Favorite Food: Ice cream. Also sandwiches.
- Why Did It Have to Be Snakes?: He used to have a great fear of vampires, especially Marceline.
- You Can't Fight Fate: Jake is a very firm believer in this, to the point where he repeatedly attempted to rush to his death due to a supposedly prophetic dream he had.
"Hurry, sweet citizens..."
The young-looking princess and current ruler of the Candy Kingdom. She cares deeply about her citizens. She's also a giant nerd, said to engage in "every branch of geekdom,", but not (as far as we can tell) in the Cosplay Otaku Girl
way— she's more of a math and science whiz. She's also a hybrid of human DNA and bubblegum DNA (which Finn finds a-TRACTT-ive~!
), despite bubblegum not having DNA
, hence her name. She's close friends with Finn, who seems to have a crush on her (however much he tries to deny it
), but she brusquely refuses any romantic advances
. She finds Jake funny and charming, and has a complicated relationship with Marceline. Although she looks sweet
, and is, in general, rather nice, she is actually quite quick to anger, and her wrath is best avoided
. She also speaks German, apparently. The second season reveals her first name is Bonnibel, and her true age has also been revealed: 827
Voiced by: Paige Moss in the 2006 pilot, Hynden Walch
in the series
- Action Girl: If the beatdown she gave Ricardio is anything go by, she definitely qualifies.
- And just to make sure it sticks, the chase and knife fight in "Wizard City".
- Actor Allusion: In "Lady and Peebles", she fights Ricardio, a villain who's essentially a living heart. It wouldn't be the first time a Hynden Walch-voiced character has ever done that.
- Affectionate Nickname: Finn sometimes calls her "Peebles", among others.
- The Ageless: In "The Suitor," PB's suitors say they have been waiting for centuries.
- Alliterative Name: Her proper name (thus far spoken only by Marceline) is Bonnibel Bubblegum.
- Anthropomorphic Food: Partly. Her hair is actually a mass of gum.
- Badass Adorable: Aww, look, how quirky and cute- Wait, is she firing lasers?
- Badass Bookworm: She has singlehandedly created a formula to reverse death itself with no side effects! Aside from being a skilled scientist, she's also surprisingly skilled in hand to hand combat, being strong enough to tear Ricardio's limbs off with her bare hands.
- Badass Normal: She singlehandedly beats Ricardio in hand-to-hand combat by just ripping off his gigantic arms and legs! Afterwards, she singlehandedly dragged Lady Rainicorn, Ice King, Jake, and Finn — all of whom were poisoned or injured — through icy terrain back to her castle for treatment.
- Badass Princess: It's pretty easy to see why the Candy Kingdom is as peaceful as it is, with someone like her in charge.
- Berserk Button: Hurting those she cares about, especially Lady Rainicorn. Ricardio found this out the hard way.
- Better as Friends: With Finn. Finn's not really happy with this, but he gets over it as of Incendium.
- On the other hand, "King Worm" and "The Lich" imply than Finn still harbors romantic feelings or bitterness for Princess Bubblegum.
- Beware the Nice Ones: As sweet as she is, to invoke her wrath would be inadvisable. Ricardio learned that the hard way.
- Big Good: She serves as the main authority figure of the series and is usually the one to who provides Finn and Jake with their missions.
- Blue and Orange Morality: Toes the line. Some of her experiments don't exactly seem all that humane or safe, for example, but it seems her priorities are too long-term to show in 11 minutes a week.
- Bunny-Ears Lawyer: Her quirks don't show too much, given the setting.
- Broken Bird: Not quite as bad as Marcy, but trauma over being possessed by the Lich is what drove her to create Goliad, she's a workaholic who emotionally detaches herself from problems, and the stress of being a No Respect Girl ruler can get to her, as well being the subject of several dogged nice guys' scary affections.
- Celibate Heroine: Of the "Love is a Distraction" variety. Finn, Ice King, Ricardio, Braco, and a throng of other suitors have all tried to woo her at one point, but she all turned them down in favor of ruling over her kingdom properly.
- The Chains of Commanding: PB occasionally expresses that she'd be relieved to abandon the responsibilities of her position, the problem being that there's no one capable enough to take over for her.
- Cheerful Child: Due to a plot-relevant age-down, she was physically 13, and cute as a button to boot.
- The Chick: Set up this way in the pilot, but the series makes it clear she fills another role - often at the same time!
- Cool Crown: It can even protect her from the Lich's mind control.
- Crazy-Prepared: In "Lady & Peebles" she tells Rainicorn that she has calculated every possible disaster and has brought everything they would need. And also implanted a GPS tracker in Finn's ear at some point in the past.
- Cute and Psycho: She can be a bit crazy sometimes, but she's still ultimately on the side of good.
- Damsel in Distress: She was captured by the Ice King in the pilot, and being his 'number one', is targeted by him on a frequent basis.
- Damsel Out Of Distress:
- She's kidnapped when she doesn't have effective countermeasures on hand when she out-and-out attacks him successfully (with a tranq gun in "The Glitch", apparently working his pinky over in "Wizards Only, Fools"...).
- She finds herself in trouble with Ricardio once again in Lady and Peebles, but she manages to beat him up this time, and it wasn't even close.
- Demonic Possession: The Lich pulls this off on her, ultimately leading to her being shattered in the fight against Finn and the Ice King and put back together, but since some pieces were missing she came back younger, as old as Finn to be exact.
- Doing in the Wizard : Even though the magic and such in Ooo was implied to be something else, even early on in the show, she's the only one to openly debunk it.
- Embarrassing First Name: Maybe. The only person who uses her first name (Bonnibel) is Marceline, who seems to be teasing her with it.
- Empress Scientist: She's the ruler of Ooo who likes experimenting with science. Although, since she is a benevolent ruler, she could be considered a Philosopher Queen.
- Flat Earth Atheist: She can be very dismissive of magic, considering it an ignorant term for the use of scientific principles that its users simply don't understand, despite the extremely bizarre nature of Ooo making her skepticism seem arbitrary to everyone else. It should be noted that it's less she doesn't believe magic isn't real, but rather everything called magic is just a subset of science, and goes so far as to call out what scientific principles are being used when she sees magic in action.
- For Science!
- Fountain of Youth: Got de-aged to 13, briefly. Otherwise ages slowly, if at all, apparently.
- Giant Poofy Sleeves: On her 'princess' dresses.
- Gratuitous German: Uses it fairly often in "What Have You Done?", and a few others.
- Growing Up Sucks: She tells Finn that she would rather stay 13 than to turn 18 again and have to deal with the responsibilities that come with being an adult ruler.
- Hollywood Science: In general, she pulls this off quite nicely. It's taken to a whole new level in "Five Short Graybles" when she uses centrifugal force, growth and shrink serums a la Alice in Wonderland, Two Beings, One Body teleportation of a jellyfish and a balloon, White Magic with a Black Magic feel, Frickin' Laser Beams, molecular fabrication, karate, a baseball bat and levitation. All to make a sandwich.
- Keep in mind that this was "the most perfect sandwich to ever exist, or will exist in the confines of space-time".
- Hot Scientist: At least for Finn. Ricardio comes around to this as well.
- 100% Adoration Rating: Her subjects would do nearly anything for her (up to and including donating parts of themselves to her) and she returns that devotion.
- It seems a large part of this is because she views the majority of the candy people as small children who require constant supervision. Honestly, given their actions, she's not that far off.
- Hypocritical Heartwarming: As much of a schmuck as Lemongrab is, he's still her schmuck, darn it!
- I Did What I Had to Do: Bonnibel has been forced to take actions that she's regretted for the greater good. Shown clearly in Burning Low when she is nearly forced to allow Finn and Flame Princess to suffocate to prevent the latter from destroying the world.
- I Have No Son: Formerly had this attitude towards her failed experiment Lemongrab. But now, she calls her two lemon creations "boys" affectionately, and they call her "Mom." They are also on better terms, although she considers them annoying and embarrassing, and they don't hesitate to blame her when they make a mistake.
- Inelegant Blubbering: Bonnibel is not attractive when she cries. When Finn agrees to help her cure her subjects of Freezer Burn Flu, the happiness plus the stress of having her entire kingdom sick nearly makes her burst into tears. Bulging, tear filled eyes, loud sobbing.
- Insufferable Genius: Pops up from time to time, in the sense that the intelligence gap between her and just about everyone else in the area is wide enough to cause problems. It's been present since "Slumber Party Panic", but really only hits a boil in "Wizards Only, Fool" - they wouldn't have had to leave the hospital if she'd just played along with Starchy's need for a 'magic' cure.
- Love You and Everybody: Feels an "undifferentiated love" for all of her candy people.
- Mad Scientist: Some episodes seem to indicate that she's not exactly quite right in the head. Add that and the fact that her scientific exploits (case in point: Lemongrab) tend to go wrong half the time, and we get this. In "The Lich", Finn and Jake find her working late into the night creating tiny candy people who farm in a tiny candy sandbox. Then she cuts off one's limbs with a scissor and attaches them to another (which they don't seem to mind much), for no stated reason.
- Mama Bear: She acts this way towards Lemongrab in "You Made Me!", and is in general willing to go to extreme lengths for the sake of the Candy citizens.
- Meaningful Name: Her first name is Bonnibel, which means "beautiful girl". Which makes sense considering she was Finn's crush from Seasons 1-3 and is the main princess the Ice King targets.
- Mini Mecha: Seems to be wearing one in "Wizards Only, Fools". What's odd is that it only covers her upper torso and follows her arms' movements, leaving her legs fully exposed (with the undersuit she's wearing possibly acting as Powered Armor, though there's nothing for or against this). It's unclear why exactly she felt the need to wear it, though she likely came directly from getting the Ice King to reveal the Wizard City password - Rorschach-style by the sound of it.
- Modest Royalty: During her off-hours, she's generally very content to hang out with Finn and Jake on their adventures wearing clothing much more simple that you'd expect for royalty, with the exception of keeping her crown.
- More Dakka: Whenever there is a pressing need for her to save her kingdom/friends through direct action, Peebles will do so with as much force as she can reasonably pull together. Note that she already has a laser-firing joystick-controlled swan bigger than she is - she had at least two guns in "Lady & Peebles", one of which was roughly equivalent to a grenade launcher.
- Motherly Scientist: Played with; she mainly comes across as a Mad Scientist, and as a result initially had a rather strained relationship with Lemongrab, who she considered to be a failed experiment. Later on, she tries to be more motherly towards Goliad, but when Goliad goes mad with power and attempts to take over the Candy Kingdom PB has no choice but to abandon that attitude in order to stop her. However, she's slowly improving her relationship with Lemongrab, and he even calls her "Mother Princess." She treats the Lemongrabs the way a frustrated but patient mom would treat her annoying "special needs" children, and calls them "boys" affectionately. She even says something along the lines of "I need to keep a closer eye on these two, so they won't get into any more trouble."
- Ms. Exposition: Often. Unfortunately, she tends to explain things from a broader perspective than necessary - "Burning Low" would have been a lot shorter if she'd given Finn the same explanation she finally gave Jake, for example.
- Nerds Are Sexy: Again, at least according to Finn. Even if he doesn't admit it.
- Nice Girl: Very nice and sweet. Until you mash that Berserk Button.
- Parasol of Prettiness: Sometimes.
- Plague Doctor: When the plague caused accidentally caused by the ice king was afflicting the Candy Kingdom, she is seen in this outfit.
- Plot-Relevant Age-Up: In "Too Young", she has to become eighteen again to regain the throne from Earl Lemongrab.
- Potty Emergency: Happens to Princess Bubblegum at the beginning of the Lumpy Space episode. "I should not have drank that much tea!"
- Pride: She's so adamant that magic isn't anything special that she refuses to pretend to use magic on Starchy to make him feel better. So she's forced to go to Wizard City and drag Finn and Jake along. The Grand Master Wizard offers them forgiveness for trespassing, so long as PB says that "wizards rule." Of course, she refuses, and gets herself, Finn, Jake, and Abracadaniel thrown in jail.
- Pragmatic Hero: Don't let first impressions fool you: she's willing to stoop pretty low in various situations.
- Princess Classic: Mostly an Affectionate Parody of the trope, but is often played straight. She is prim, proper, poised, is frequently a Damsel in Distress, and loves pink.
- Princesses Prefer Pink: And how! Note that she does have other outfits, several of which aren't very pink - the ones she wears as Princess are all pink-ish, though.
- Rapunzel Hair: Goes down to her knees (when she has it down).
- Really 700 Years Old: She's at least 300. In "The Suitor", it's revealed PB's various suitors have been waiting to court her for hundreds of years.
- "The Vault" is the first episode to directly confirm that PB is actually quite ancient; when confronted about it PB seems to view it as an embarrassing secret.
- In the game Adventure Time: Explore the Dungeon Because I DON'T KNOW!, she tells the Ice King that she's 827 years old.
- Rose-Haired Girl: Though this is due to her hair being a bubblegum-pink mass of...well, bubble gum.
- Royals Who Actually Do Something: May actually be the most active of all the Princesses in Ooo.
- Science Hero: Bubblegum's scientific intellect has gotten Finn, Jake, herself, and the whole kingdom out of trouble at times - even if it was her scientific exploits that got them into trouble in the first place.
- Sherlock Scan: Bubblegum is shown to have this ability in "Sky Witch"
- The Smart Girl: She's very skilled when it comes to scientific matters. Not like it's hard.
- Sophisticated as Hell: She provides shades of this, shifting from words like "shall" and "beseech" and phrases like "You seem genuinely penitent" to words like "hun" and "ah-ight" and phrases like "You'd better not freakin' tell anyone!" and "Mondo momma brains!" and "ballblamburglerber".
- Sour Supporter: Spends most of "Wizards Only, Fool" like this. It's highly uncharacteristic of her, but as she's clearly having to go considerably out of her way (both physically and philosophically) to satisfy a request from one of her subjects, it makes sense.
- Spear Counterpart: Prince Gumball.
- Spoiled Sweet: Literally. Well, most of the time.
- Teen Genius: Likely the smartest being in Ooo. Though how 'teen' applies to her is a little questionable.
- Tomboy and Girly Girl: Girly Girl to Marceline's Tomboy, with appropriate consequences to Marceline's dating advice for Finn. (The show makes it clear that Bubblegum is fully capable of doing 'tomboy' things, and the trope as it is applies primarily to their preferences.)
- Took a Level in Badass:
- In the dungeon episode with her magic flying swan that shoots lasers from its mouth by controlling it like a joystick.
- In "What Have You Done?" Princess Bubblegum was about to beat the stuffing out of Ice King... using pink Power Fists.
- In "Lady and Peebles", she defeats Ricardio in hand-to-hand combat by tearing off his arm and leg and essentially pummeling him with the very limbs he made for himself.
- "Reign of Gunthers" solidifies her badass status as she is seen for the first time with a sword and battle attire.
- Town Girls: The Femme to Flame Princess' Neither and Marceline's Butch.
- Treehouse of Fun: Her castle is built around a tree.
- Tsundere: Type B.
- Unfit for Greatness: Half the time she calls on Finn, it's to make up for her own oversights. Understandably, a lot of this is due to how thinly stretched she is as top scientist and best living diplomat in Ooo, in addition to running the Candy Kingdom part time with little help better than Cinnamon Bun.
- Unlimited Wardrobe: At least fifteen outfits besides her stock pink dress.
- Unwanted Harem: There was a point that Finn, Ice King and Ricardio all had crushes on her. She wasn't comfortable with it.
- She literally has a harem of suitors waiting to date her as seen in "The Suitor." She makes it clear that she wants to focus on her studies and doesn't date. Because of this, some of the suitors have been waiting hundreds of years.
- Well, Excuse Me, Princess!: Marceline kinda implied this regarding her relationship with Princess Bubblegum in her song in 'What Was Missing'. "Sorry I don't treat you like a goddess", indeed.
- You Do NOT Want To Know: Finn, Jake, and Marceline all agree it is best not to know what PB is up to in her lab.
"이게 더 좋아?" note
An odd-looking but beautiful, flying half-rainbow-half-unicorn creature. Also Jake's girlfriend and as of season 5, the mother of their children
. She only speaks Korean, which Jake, but not Finn, understands.
- Action Girl: She's not afraid to go into combat.
- Badass Adorable: She's able to keep up with Finn and Jake in "My Two Favorite People", and she even has to save Finn from the army of lake monsters. Surprising, considering she looks like a little girl's toy.
- Beta Couple: Forms part of one with Jake.
- Bilingual Bonus: Given that she only speaks Korean, this is inevitable.
- Casual Kink: She's often innocently flirtatious with Jake in public.
- Cool Pet/Cool Horse: Both her and her male and monochrome counterpart.
- Covert Pervert: Some of her untranslated remarks to Jake are raunchy as all hell.
- Demoted to Extra: Lady appears in three episodes in Season 4: one as a cameo, one as a figment of Jake's dream, and one as a major character. But it was a hell of an episode.
- Everything's Better with Rainbows: Crossed with unicorns? Even better.
- Her Name Really Is Barkeep: She doesn't have a noble title- her given name actually is Lady and Rainicorn is her family name as well as her species.
- Intangible Rainicorn: She can phase through walls, as revealed in "The Creeps".
- Interspecies Romance: She (rainicorn) forms a Beta Couple with Jake (bulldog).
- Multicolored Hair: Inverted; she has normal blonde hair, but a multicoloured body.
- Nice Girl: She is never shown to be anything but kind and placid, even making the effort to spend time with her boyfriend's kid brother just to get to know him.
- Non-Human Sidekick: To Princess Bubblegum.
- Not Quite Flight: She technically rides on reflected light. She turns in early, but can still fly by night.
- OOC Is Serious Business: Other than when she's using the Universal Translator, Lady only has one line of English dialogue in the series: "I am pregnant!"
- Parental Abandonment: Averted as she is the only character shown to be on good terms with both of her parents.
- Pregnant Badass: Serves as Bubblegum's steed even when carrying babies.
- Spear Counterpart: Lord Monochromicorn.
- Technobabble: She flies by... er... dancing on photons?
- Undying Loyalty: Her translated dialogue shows that she thinks very highly of Princess Bubblegum and takes great offense at any intrusion on the Princess' honor.
- Unicorn: Half, anyway.
- The Unintelligible: Finn can't understand her in the 2006 pilot—Jake can.
"Who wants to play video games?"
BMO, pronounced Beemo
, is Finn and Jake's cute Animate Inanimate Video Game
system. A bit of a rebel, Beemo sometimes enjoys turning up his volume too loud and running out of batteries during a game. Speaks with a Korean accent, and looks like cross between a Game Boy
and a Vectrex
. Was built by pre-Mushroom War robotics engineer Moseph Maestro Giovanni to be a companion and best friend to the son he never had and eventually sent into the world by said inventor to "Be More" and find a family
Voiced by: Niki Yang
- Ambiguous Gender: Typically referred to as a "he", but was referred to as "M'lady" by Finn in the season 3 premiere. However, he (?) called himself (?) a boy in "Five Short Graybles". And in "Five More Short Graybles" his (?) alter ego claimed to be a girl. The version of him/her seen in the Fionna and Cake stories looks exactly the same, so that's no help either.
- Animate Inanimate Object: It's a living video game console.
- Become a Real Boy: Or it wants to, anyway.
- Breakout Character: Has had a couple of limelight episodes, infact.
- Bi the Way: Shown romantic interest in a female chicken and a male bubble. Regardless of his/her gender, s/he has shown interest in characters of both genders.
- Cassandra Truth: When Jake tells BMO not to mention any of his past life of crime to Finn in One Last Job, but BMO manages to forget keeping it a secret from him. Finn dismisses it as BMO being over-actively imaginative anyway.
- Cerebus Syndrome: While developed initially as a comedic character to play off of Finn and Jake, BMO has grown to be a very complex character with its two episodes "BMO Noire" and "BMO Lost". Its association with minor episodic characters are often actions of brutality, love, matronly care, or despair. BMO's character arc reached a new level of emotional power in "BMO Lost" when it arrived back home with Bubble. As BMO knocked on the door, Bubble was saddened he would never see his home, but felt he had gotten to know BMO well enough to ask for its hand in marriage. BMO agreed, only seconds before Jake popped Bubble, not knowing his was alive. BMO broke down in tears as Finn and Jake laughed at it. However, Bubble was resurrected, realizing all this time he was Air. Then it goes straight into Stalker with a Crush territory as Bubble explained he would surround BMO in every room, in every space, forever, until the end of time. BMO cheers at this. Damn...
- Cloud Cuckoolander: As evidenced in the kinds of games it creates, such as an Abraham Lincoln fighting game and "Conversation Parade". Also has a bizarre imagination.
- Covert Pervert: It watches two slugs make out in "Slow Love".
- Cute Machine: Lampshaded by Marceline in "Evicted".
Marceline: "I'm invested in this very cute video game!"
- A Day in the Limelight: "BMO Noire", "BMO Lost" and "Be More".
- Do-Anything Robot: BMO can serve whatever function is convenient for the plot. For instance, one time it edited and played back a home movie with a custom background song.
- And sometimes subverted, like the "ghost-detecting machine" in The Creeps.
Bubblegum: So, who's the ghost, BMO?
BMO: Oh, um... I don't have ghost-detecting equipment. I just like taking nice pictures.
- Eating Machine: BMO's very fond of hot chocolate despite not actually having a mouth.
- Grew Beyond Their Programming: Mo built and programmed him to "Be More" then just an average robot
- Magic from Technology or Magitek: No further explanation is given how a video game came to life and gained consciousness, which leads to fan speculation.
- Eventually is revealed to be a unique robot built by the MO robotics company programmed to "Be More"
- Malaproper: Especially in "BMO Noire".
- Massive Numbered Siblings: While unique, BMO's creator made a large number of other Mos, who recognize BMO as family.
- Mirror Monologue: Only in the graybles so far.
- Mr. Imagination: Takes it to really bizarre heights.
- Name's the Same: Shares his abbreviation (and colloquial pronunciation) with the Bank of Montreal, which makes the show kind of amusing for Canadian viewers.
- No Biological Sex
- Phantom Zone: It's only ever been seen in one episode so far.
- Retraux: Crosses over into this, as it displays pixellated graphics and plays 8 bit music.
- Protectorate: Jake orders BMO to watch over a distraught Finn while he heads off to the Flame Kingdom. BMO's reacting a little too enthusiastically is pretty much par for the course.
BMO: If anyone tries to hurt Finn, I will kill them!
Jake: ...Okay, good.
- Talking Appliance Sidekick: More of a supporting character than "sidekick" but it still counts.
- Tin Man: In "Donny", Beemo states how as a machine it can not feel pain or emotion but states that it very much hates Donny.
- Tagalong Kid: While certainly not a kid in the conventional sense, it's often treated like a rebellious child by Finn and Jake, particularly in "Slow Love". Which may qualify as Hypocritical Humor, given that Finn is a Kid Hero and Jake acts like One of the Kids.
Lumpy Space Princess
Marceline the Vampire Queen
"Dang, man, I didn't think you'd ever catch on!"
The queen of the vampires (or so she says). Known to be extremely unempathetic but never cruel, simply doing whatever she pleases even at the expense of others. Was alive at the time of the apocalyptic 'mushroom war'. Subject to a lot of fan "attention"
, for whatever
reason; became extremely popular
while only appearing twice in the first season, not counting the opening credits and brief cameos.
Usually decked out in punk-rock apparel. She generally tries to be cool and rather unfeeling, she harbors a very broken spirit due to loneliness in living forever, among other things. Whenever her more sensitive or emotional side is shown, she gets angry. She and fellow immortal Ice King also share a long and painful history together, and she spends much of her time finding and moving into new houses to avoid him.
In the fourth season, it was revealed she has the surname Abadeer.
Voiced by: Olivia Olson and Ava Acres(as young Marcy), and Cloris Leachman as the elderly Marceline in the Farmworld universe
- Affably Evil: When she was an antagonist (which lasted for about one episode, not counting her trickery in "Henchman"); since then she's settled into a more neutral type of personality with a general Lack of Empathy, being more Affably Amoral than anything.
- Affectionate Nickname: Finn and Jake sometimes call her "Marcie". Ash calls her "Mar-mar".
- Age Without Youth: Originally; the Farmverse reveals that as a half-demon, her lifespan is well over 1000 years naturally, but without the added bonus of vampirism, her body and magic will vastly deteriorate into old age.
- Anti Anti Christ: It's suggested because her father is evil incarnate.
- Attack of the 50-Foot Whatever: Does this all the time, but thus far never in her Cute Monster Girl look; she prefers scaling herself up into monstrous forms for combat purposes. See One-Winged Angel below.
- Bat out of Hell: Frequently turns into a odd-looking bat when she wants to hide, and she has a giant version that she assumed in her first appearance.
- Berserk Button: Never steal her axe-bass. 'What Was Missing' suggests that calling attention to her more sensitive side is another button for her.
- She also takes offense to anyone questioning her "punk rock" cred.
- Blood Knight: Possibly. She did give Finn and Jake their house back mainly because Finn gave her a good fight, and in 'Go With Me', she seems to approve of Finn's idea of fun centering around wrestling and fighting.
- Breakout Character: She's one of the main cast now, though her major appearances are fairly infrequent.
- Broken Bird: She's had a very harsh life, been betrayed by a lot of people, and scares people away out of fear of it happening again.
- The Cameo: Happens in "The Duke" for a second near the end, has a non-speaking role in "Movie Makers", and in "Power Animal" at the party in the beginning.
- Characterization Marches On: Goes from being antagonistic to a Heroic Neutral.
- Combat Sadomasochist: A minor case.
"Yeah, it hurts, but I kinda like it. It reminds me of when I'd scrape my knees up as a kid, and my mom would patch me up. You know what I'm sayin'?"
- Cool Old Lady: In the farmverse, though she is pretty batty.
- Creepy Child: As a child, and spoken to her teddy bear as she was fixing it: "I'm hurting you because I love you." What really drives it home is that she's completely unfazed at the Scenery Gorn that the Mushroom War has brought.
- Creepy Good: She may be an ally, but Finn and Jake are still terrified of her.
- Cute Bruiser: As a child, but able to casually tear a mailbox apart like it was paper.
- Cute Little Fangs: Though it's fairly clear that her entire mouth is full of sharp teeth.
- Cute Monster Girl: As a little girl.
- Daddy Issues: Her daddy in question is rather neglectful and ate her fries she bought when she was young.
- Dark Is Not Evil: Sure, she's a Vampire Queen responsible for kicking Finn and Jake out of their house (although she does return it), but for the most part she just wants to jam on her axe and record albums with friends.
- Eerie Pale-Skinned Brunette
- Et Tu, Brute?:
- Everybody she's ever loved has betrayed Marceline. First her mother passed away, then her dad ate her french fries and finally her boyfriend Ash sold her teddy bear. So these days she scares people away so they won't hurt her.
- And now it was revealed that Ice King was a father figure to her, but he doesn't remember his past with her due to his insanity.
- Everything's Squishier With Cephalopods: She has the ability to turn into a giant tentacle monster. She did it in order to dissuade Finn from asking her out before realizing that he wasn't interested in a date.
- Family-Unfriendly Death: In the Farmworld, she is killed by the explosion caused by Finn's mayhem.
- Famous Last Words: In the Farmverse.
Marceline (To Finn): I warned ya, you butt!
- Felony Misdemeanor: By itself, her dad eating her fries would seem this, but with a little closer look it serves as another indication that her father never took her thoughts or feelings into consideration, and that taking something that belonged to her, which at this point happened to be something completely trivial, was the final straw.
(singing) "Daddy, do you even love me? Well I wish you would show it, because I wouldn't know it. What kind of dad eats his daughter's fries, and won't look her in the eyes? There were tears there. If you saw them would you even care?"
- Flight: Her most used power. It's fairly rare to see her actually touch the ground.
- Friendless Background: In "Memory of a Memory" we see a flashback of her as a child, describing her stuffed animal Hambo as her only friend; in "Marceline's Closet" she writes a song to the same effect. We later discover that she did have an Intergenerational Friendship growing up with Simon, who gave her Hambo, but that didn't end well.
- Friendly Neighborhood Vampire: Depends how she sees you. She can be your best friend or worst enemy.
- Fur and Loathing: The dress she wears in "Henchman" is made from a Whywolf. "Marceline's Closet" shows that she also has a large fur-lined coat, with the head and claws built into it.
- Giant Flyer: Again, see One-Winged Angel.
- Girl with Psycho Weapon: If she doesn't want to kill you with her powers of vampirism, she could use her demonic axe bass.
- God Save Us from the Queen!: Played With
- Good All Along: Sort of. (see Heel-Face Turn)
- Half-Human Hybrid: Born half demon and became a vampire later.
- Heel-Face Turn: In her original appearance, she comes in the middle of the night and kicks Finn and Jake out of their own house, leaving them out in the open trying to find a place to live. When they finally do find a place, it just so happened to have been Marceline's... and so she almost kills Finn and Jake, but in the end, gives them their house back because she forgot how much she liked the cave. Second appearance, and Finn and Jake still consider her an enemy. Finn unwillingly becomes her accomplice to her many dark deeds that all turn out Double Subverted. The last scene shows that Finn and Marceline have gained some trust for each other. Third appearance, Finn and Marceline spend the entire episode together, trying to get her soul-sucking father back into the Nightosphere.
- She's even gone so far as to show genuine concern and even go out of her way to save Finn and Jake in at least one situation where their lives were put in danger.
- Heroic Neutral: She's far and away the most powerful ally that Finn and Jake have, but is very difficult to motivate into helping solve a problem. The few times she is willing to fight seriously, she's either outclassed by the threat (facing her father) or some supernatural rule prevents her from doing much.
- I Just Want to Have Friends: Extremely strongly implied; in 'What Was Missing', the Door Lord didn't actually steal anything from her, she just wanted to hang out with her friends and gets intensely embarrassed when this is pointed out. In 'Memory of A Memory', it's shown that she was a borderline Extreme Doormat when it came to her Bastard Boyfriend Ash until he sold her only fond childhood treasure for an entirely pointless reason.
- If you don't take it as a expression of Les Yay, Marceline's song to Bubblegum can be considered an expression of this; she doesn't even remember why Bubblegum is angry at her and feels she shouldn't have to apologize, but implies she still wants to.
- She outright admits that she hides tears because she has no friends in "Marceline's Closet". And in "I Remember You" she desperately cries while unsuccesfuly trying to make Ice King remember his life as Simon and their old friendship.
- Ill Girl: As a child. Simon has to find her chicken soup to restore her to good health.
- Immortal Immaturity: She's been around for at least a thousand years, but she's really not too much more mature than Finn himself is. At times, he's even more mature than her.
- Immortality Begins at Twenty: Appears to be about Princess Bubblegum's age.
- Subverted in the Farmworld, where she has aged badly. Seems she's naturally long-lived - she's quite spry for her age - but probably didn't get the chance to become the Vampire Queen.
- Informed Ability: Is the Vampire Queen, but seems to be the only vampire in Ooo. Similar-looking characters like her father and her ex-boyfriend Ash are said to be different kinds of creatures in the show or via Word Of God.
- Another definite vampire, Keira the band's lead guitarist, appears in Marceline And The Scream Queens. While she does defer to Marceline, that's because she's the band leader and no mention is made of her being the "Vampire Queen". Additionally, the comic is of ambiguous canonicity relative to the main series.
- Instrument of Murder: She turned the family axe into a bass guitar.
- Invisibility: Uses it to sneak in on Ice King's "Fionna and Cake" reading session, and for cheap laughs in "Heat Signature". (It's apparently a vampire power... but she's in the midst of messing with Finn and Jake when she says so.) Given her personality, it's not surprising that she doesn't use it often.
- Intergenerational Friendship: Had one with Simon Petrikov during the aftermath of the Mushroom War. Has one with Finn and Jake.
- It Amused Me: This is her reason for pretty much everything she does, Jerkassy or not.
- Jerk with a Heart of Gold:
- Seemed to be a straight-up Jerkass in her introduction episode (in the "Evicted" song, she sang that she was "1000 years old and just lost track of her moral code"), and then in "Henchman", it was revealed that she's actually a pretty cool chick who enjoys screwing with people but never actually hurts them, and by the end of the episode she and Finn seem to have struck up a friendship, and though Jake presumably still hated/was totally terrified of her, he seems to have warmed up to her to the point of being worried about her when told she was in danger. Since then, she's pretty much dropped pretensions towards straight-up Jerkassery.
- "Heat Signature" provides a good example of this; she pranks Finn and Jake into believing that they're vampires and fools them into doing various embarrassing things, but draws the line at her old ghost gang brutally kicking them for no reason and goes berserk when Finn and Jake are tricked into nearly jumping to their deaths.
- Just Friends: With Finn. 'Go With Me' confirms that neither of them have feelings for each other that way, but it hasn't stopped shippers.
"I only try to kill you 'cause you're PRINCESS-BLOCKING ME ALL THE TIME."
An unruly monarch from the Ice Kingdom. He can be considered one of the main antagonists of the show, constantly stealing princesses so he can marry them. Once a close friend of Marceline's, he's spent years pestering her. She says that she tolerates his presence because she loves him unconditionally, and remains one of the few characters to bestow compassion upon him to date.In truth, these are but the remnants of a pre-apocalypse professor of archaeology and antique enthusiast once named Simon Petrikov, before he was possessed and transformed by the arcane forces of ice and snow within a crown he bought. The subsequent bouts of madness estranged him from his beloved fiance, Betty, and his nickname for her, "princess", was warped by time and insanity into his compulsion to kidnap and marry princesses in present day Land of Ooo.
Voiced by: John Kassir in the 2006 pilot, Tom Kenny in the series
- Took a Level in Kindness: In "Hitman" when he saved Finn and Jake's lives three times.
- Tragic Villain: In a pre-apocalypse Earth, an intelligent, mild mannered antique dealer named Simon Petrikov procured an ancient magic Scandinavian crown. After putting it on in jest, the Crown seized his mind and began altering his body, giving him power over ice. The process, the constant spectres and visions drove him utterly, completely mad, into his present state. The Ice King no longer seems to understand what's happened to him.
- Unwitting Instigator of Doom: In "Mortal Folly", his pestering of Finn and Jake for their approval to court Princess Bubblegum ruins their best shot at destroying the Lich, who after regaining his power via the Well of Power, destroys the Gauntlet once used to destroy him that Finn himself was about to use. After the Lich is destroyed, the Ice King screws up again by dropping the Princess into the well, which results in the latter being possessed by the Lich, and later, being reduced to a 13-year-old after pieces of her are still missing. Which results in Earl of Lemongrab dropping in to assume a tyrannical rule over the Candy Kingdom. Whew. At least the latter lasted only one episode.
- He has also been revealed to be the original discoverer of The Enchiridion, a book which holds great importance to The Lich.
- Villainous Rescue: Assists Finn and Jake against The Lich to save Princess Bubblegum.
- Villainous Friendship: Gunter the penguin is probably his best friend.
- Was Once a Man: He used to be a (human) artifact collector named Simon Petrikov, then he started wearing his crown, which drove him insane and gave him powers over ice.
- Weaksauce Weakness: Losing his beard leaves him flightless and losing his crown removes all his powers. He is also unable to use his ice powers in high temperature environments (along the lines of a steam room or sauna), though can apparently still fly in tropical ones.
- Wistful Amnesia: He may not remember, or be capable of being reminded, of his past, but on some level he still remembers enough to drive him to kidnap princesses out of a desire for Betty, and bug Marcelline out of the knowledge that she's important to him, even if he can't remember why.
- With Great Power Comes Great Insanity: Yep, powerful and crazy. And not only was he not always either of those, he achieved both conditions at the same time by the same process.
- Wizard Beard: A functional one. He uses it to fly.
- Woobie, Destroyer of Worlds: If more likely to freeze them.
- Yandere: A rare male example.
An undead sorcerer who is supposedly Ooo's greatest evil. He has an army of the living dead and vast magical powers. He was defeated and sealed away in amber inside of a great tree by the legendary hero Billy. Not a funny character at all.
Originally called the Lich King, renamed to avoid confusion with that other guy
In season 5, it was revealed that he was created by the nuclear radiation released from a bomb used in the Mushroom War.In "Finn the Human" an Alternate Timeline is created where the bomb wasn't detonated in an attempt to keep the Lich from existing. Unfortunately a series of events in "Jake the Dog" leads to the bomb detonating 600 years later in the present day, creating a new Lich from Jake.
- Bag of Holding: Gets his hands on one in the comic, his plan being to suck up the entire land of Ooo then throw the bag into the sun.
- Bigger Bad: The Lich is the most powerful and evil villain in the show, but due to being sealed in an amber prison inside a great tree, he didn't have a huge role up until the season 2 finale. Later subverted when it's discovered that the Lich is a product of the Mushroom War, making the true Bigger Bad humanity.
- Big "NO!": INVOKED of all things. What better way to get the hero to do something than to shout "Nooooo!" when he does it?
- Body Horror: Are those tendons hanging off his arms?
- His undead appearance is implied to be a mutation of a normal human.
- Body Surf: Finn destroys his real body, so his soul transfers into Princess Bubblegum. After he's defeated again, he transfers again into the Snail. However, given the Lich is still in the body of the Snail, it seems he's stuck in his body until it's destroyed. He transferred to Billy at some point. According to Prismo (who would know), he's a "ghost wearing a dead guy", so Billy is dead.
- Casting Gag: Of the darkest kind: Ron Perlman provides the unsettling opening and closing narration for the Fallout series of videogames, wherein an intrepid hero explores a nuclear post-apocalyptic earth filled with strange mutated creatures and insane factions.
- Chekhov's Gunman: First appeared in the season 1 finale for about a second in Billy's song, becomes the Big Bad of the second season finale.
- Compelling Voice
- Crystal Prison: Is encased in amber as of the beginning of "Mortal Folly".
- Dangerously Genre Savvy: The reason for It Only Works Once. It's not that he becomes immune to whatever defeated him, he just makes sure to prevent prior tactics from being used on him again by aggressively targeting the source of his defeat and either destroying it or manipulating it to his own advantage. Billy's gauntlet was used to defeat him before, so one of the first things he does is destroy it before Finn could effectively use it against him.
- Dark Is Evil: AND HOW!
- The Dreaded: According to Word Of God, he's so terrifying that even the Ice King and Marceline will run in terror of him. Princess Bubblegum's reaction to the possibility he's returning in the preview seems to further support this. It winds up being partially averted in the actual episode, as although Princess Bubblegum does truly fear him (Marceline does not even appear), Ice King seems to be completely clueless about the Lich due to his Cloudcuckoolander nature (being more concerned with holes), and he actually eagerly volunteers to help fight the Lich later on.
- "King Worm" implies that even Finn is afraid of him (and possibly his greatest fear, enough to wake him from his dream).
- It's so bad, even the creators are scared of him. In the original pitch document, underneath an early sketch of the Lich is the phrase "The Lich King is Not Funny".
- Evil Is Deathly Cold: "Aren't you cold, Finn?"
- Evil Laughter: Suddenly breaks into a sudden fit of laughter just seconds before Finn destroys his original body.
- Evil Sorcerer
- Evil Sounds Deep: He has a very low and menacing voice, courtesy of Ron Perlman. Although it was supposed to be even deeper, as Pen's original choice was Tom Waits.
- Face Monster Turn: Implied to be a human mutated into a weapon.
- From Nobody to Nightmare: While who or what he was isn't made clear, he was a member of the Pre-Mushroom War civilization before the nuclear pollution mutated him into the immensely powerful Omnicidal Maniac. Though considering his Body Surf abilities, the core personality of the Lich probably wasn't some innocent victim, just the body of the dude he used.
- Generic Doomsday Villain: The Lich is arguably this trope done right: he doesn't have much personality beyond a single-mindedness towards his goal, but this allows him to focus on being really cunning when trying to accomplishing his goal-and his origin is thematic enough to justify said single-mindedness.
- Glowing Eyelights of Undeath: He and anyone he's controlling have these. At least at first: see Morphic Resonance.
- Hero Killer: One of the more successful examples. Just ask Billy.
- Immortality: Appears to have this, a combination of types four and five, due to being a Lich and his habit of Body Surfing. Word Of God has said that he hasn't beaten death but is cheating him at every turn.
- It Only Works Once: Happens twice; Billy's Gauntlet was supposed to be needed to kill The Lich since it worked before. Destroying it is among the first things he does, before even fully recovering. Attacking him with The Power of Love didn't work out so well the second time either. It's not so much that whatever he gets hit with won't work on him again, he just has whiplash-quick reflexes and really long arms.
- Billy only worked once, considering the Lich is now using him as a body suit.
- It's a Wonderful Plot: An interesting case in which Finn wishes this on him. We then see what the world is like if the Lich hadn't existed. It ends up backfiring as Jake becomes the stand-in for the Lich in the alternate timeline.
- Knight of Cerebus: Oh hell yes. The first thing you'll notice about him is that unlike the other villians in this show, he has no humorous quirks that can make him any less terrifying.
- Manipulative Bastard: He managed to use Reverse Psychology on Finn to gain access to the Multiverse.
- Morphic Resonance: His vessels retain his Glowing Eyelights of Undeath... ...until he realized this would be a dead giveaway and took the time to make his disguise perfect.
- Mind Rape: Has this ability if one isn't wearing the proper magical protection or The Power of Love.
- Necromancer: Well, he is a lich.
- Non-Standard Character Design: Most of the main cast are made of simple cartoony shapes and bright colours without much detail. The Lich is made from complex shapes that make him look more human, uses dark and threatening colours along with his trademark Sickly Green Glow, and has a lot of detail on his face and all the tendons and flaps of skin hanging off his frame.
- Night of the Living Mooks: Has an army of the living dead.
- Nightmare Face
- Nuclear Nasty: Implied to have arisen as a result of the Mushroom War's radiation storms, if "Jake the Dog" is anything to go by.
- Obviously Evil: His demonic face, dark cloak, skeletal body, and dark magic just make it pretty clear that he's a villain.
- Oh Crap: When he realizes he wished for Finn and Jake to return home safely instead of wishing for the end of all life (thanks to Jake's wish).
- Omnicidal Maniac: According to Princess Bubblegum, his goal is to destroy life. His original wish to Prismo was to destroy all life.
- It's implied that this is because he's a spawn of the Mushroom Bomb, and is trying to finish off the job.
- One-Winged Angel: In Princess Bubblegum's body, he tricks Finn into getting him the things he needs to fully regain his powers and turns into a gigantic monster that beats the stuffing out of Finn, the Gumball Guardians protecting the Candy Kingdom, and Jake, then tears apart the Candy Kingdom. It ultimately takes an Enemy Mine with Ice King to defeat him. And even then, his soul transfers again.
- Our Liches Are Different: He was created by nuclear waste.
- Person of Mass Destruction: Luckily, he didn't regain his full power...yet.
- Playing with Fire: Has the ability to shoot green flames from his hands.
- Psychic-Assisted Suicide: Tried to make Finn walk into his well, which would likely have killed him (or mutated him horribly).
- Sealed Evil in a Can: Was imprisoned in amber by the legendary hero Billy. Unfortunately, said amber turns out to be extremely fragile.
- Sickly Green Glow: If it isn't the flames he shoots it's the bubbling potion he uses to regain his power. It at least has plutonium in it.
- The Undead
- Vile Villain, Saccharine Show
- Walking Wasteland/Touch of Death: He leaves path of death and destruction in his wake. After he possesses Princess Bubblegum, he uses this to wilt an entire room full of flowers with one touch.
- We Can Rule Together: He attempts this on Finn in the Season 4 finale. It turned out to be a Batman-Gambit played on Finn's heroic personality. He rejected the offer and smashed the Enchiridion, which was exactly what the Lich wanted. Had he joined him, the same thing would have played out anyway.
- Worf Had The Flu: Finn managed to beat him in the first fight, only because he was prevented from regaining his full strength. When he did later, he's powerful enough to deliver a Curbstomp Battle to Finn, Jake, and the Gumball Guardians of the Candy Kingdom, requiring an Enemy Mine with Ice King to defeat him. Even without his full power, he was able to shatter the gauntlet given to Finn to kill him and knock out Jake in one blast.
"Don't EVER mess with me again..."
The princess of the Fire Kingdom; who is made out of fire. Beneath her innocent exterior is a deeply destructive and unpredictable personality, with a terrible temper. She has no perspective on the norms of the world and doesn't seem to understand what is right or wrong, likely due to being sheltered by her father. At the end of the third season, she inadvertently becomes Finn's new love interest
. By the fifth season, it's clear that she's growing into a more settled personality, having spent time interacting with the world. She eventually usurps the position of ruler of the Flame Kingdom from her father.
Voiced by: Jessica DiCicco
- Always Chaotic Evil: Subverted. She thinks destroying things is fun - but only evil things, as mentioned at the end of "Vault of Bones". While the rest of her races is played straight, she seems to be more solidly Chaotic Neutral, as she tends to handle situations like a Nineties Anti-Hero. However, she will not, under any circumstances, willingly hurt her boyfriend.
- Ambiguously Evil: Was this for a good while until the truth came out: she is not truly evil after all, just emotionally disturbed due to being locked in a lamp most of her life because of her having world-destroying powers. However, her father, The Flame King, does state that she and everyone else in the Flame Kingdom are evil, but spending enough time with a good person can potentially change her over to the side of good (although she'd suffer penalties to her experience for doing so).
- Apocalypse Maiden: She is so emotionally unstable that engaging in kissing makes her physically unstable to the point of causing her to heat up enough to melt through the earth's crust and burn up the entire planet. Luckily, that appears to be the only trigger so far.
- Armor-Piercing Slap: On Finn.
- Attack of the 50-Foot Whatever: As she is basically living flame, she's grown to the sort of size this trope covers once or twice, though it's tied to her emotions more than her destructiveness.
- Ax-Crazy: Whether you think she is good or evil, it's clear she enjoys burning things a little too much, made abundantly clear after going on a rampage in "Vault of Bones"
Flame Princess: YES! FEEL MY FLAME, PUNY WORMS! THE POWER OF DESTRUCTION!
- Badass Princess: It is very likely that she is the most powerful princess in Ooo, and she could probably destroy an entire kingdom if she wanted to. In her second episode, she came dangerously close to doing just that (to the Goblin Kingdom, to be precise). She only stopped because she was distracted by Finn crying.
- Baleful Polymorph: Turns several Fire People into Fire Cats for whispering. This is not the first time she's done this.
Flambo: So that's where I came from.
- Berserk Button: Do not lie to her. Ever. And if she likes you, do not reject her. It's also not recommended to keep switching feelings for her. She's also still pretty angry at her father for locking her up in a lamp for most of her life. Speaking of which don't bring up her childhood or call her sweetheart as a result. And don't make fun of her, unless she's cool with you and you do it in a respectful manner.
- Blue and Orange Morality: Tends to see the world in terms of elemental forces. This works out okay for Finn (he's a "water elemental" with lots of "magic air" in him), but she torches the Goblin Kingdom pretty good in "Hot to the Touch" just fulfilling her elemental destiny (with 0.0 casualties, thankfully). Note that this worldview appears to be unique to her, and isn't shared by any other Fire Kingdom denizens. On top of that, she seems to be trying to approach a more 'normal' worldview over time.
- Burning with Anger: Flares up into a more monstrous form when angry. Kinda like a... Bedsheet Ghost made of fire? Also when using her flame powers - the more area-effect they are, the less humanoid she is.
- Can't Have Sex, Ever: A more kid-friendly version: since her powers are influenced by her emotional state, extreme ones like passion and love brought on by something as innocent as a kiss could ignite her so much, her body could burn so hot she could end up burning a hole into the center of the planet. Naturally, she and Finn have to find other indirect methods of dealing with this.
- Chaotic Neutral: Finn, at least, thinks she's this. (Makes sense, since she hews closer to an elemental interaction than any real character alignment, at least initially.)
- Character Development: Her time spent with Finn (and probably just as likely, time spent away from her father and the Fire Kingdom) has rounded her out some, and she is taking steps to be less volatile. She's also shaping up to be a far more fair ruler than her father was.
- Cute and Psycho: Justified by her background. She seemed to be improving with Finn's company, though, and by "Vault of Bones" she's more "Cute And Enthusiastic-about-burning-things". Since they've broken up, however, she's become more serious.
- Daddy Issues: She's got some animosity with her father thanks to him sealing her in a lantern for most of her life.
- Calling Your Attacks: Does this a few times in "Vault of Bones"
- Does Not Like Shoes: Her first dress. She wears slippers (flats?) with her second dress - maybe she has a better grasp of outside culture by that point? Though her third dress in Vault of Bones she is back to being a barefooter.
- Elemental Embodiment: To make matters worse, all the fire she creates is actually a part of her - any attempt to curb her destruction causes her pain. However this means that she has absolute control of her fires and so far has chosen to not harm a single non-flame non-evil creature, even when she set an entire inhabited city alight. She currently lives in a house that is a fire on the outside and wood (with books on the wall) on the inside.
- Enfante Terrible: She burned down a large forest outside of the Candy Kingdom as a baby, garnering the attention of Princess Bubblegum and leading to her being sealed away.
- Evil Is Burning Hot: Gradually getting closer to an aversion with each appearance. By "Vault of Bones", it seems unlikely that she's evil at all, and certainly has no wish to be.
- Expressive Hair: When we first meet her, her hair is in the shape of a flame (as pictured above) and at that point she's very temperamental and unpredictable in her moods. In "Vault of Bones", her hairstyle has changed to a more normal-looking bob haircut, only flaring up into its former style when she's startled, and personality-wise she's calmed down quite a bit. This could mean that her first hairstyle indicated how emotionally unstable she was.
- Fiery Redhead: Has a fiery personality that meshes well with Finn's, to go with that red hair, and tends towards a direct approach and impatience. Also literally, being fire in humanoid shape and all.
- Flaming Hair: Always on, even when she's sleeping.
- Flight: Capable of it, as seen in "Frost & Fire."
- Glass Cannon: She can set whole fields ablaze in an instant, yet feels pain when those flames are extinguished, and can herself be doused like a flame. When exploring or adventuring with Finn, she's more of a Squishy Wizard.
- God Save Us from the Queen!: Averted to hell and back when she becomes queen of the fire kingdom after overthrowing her dad. She simply wants people to just be honest, imprisoned her dad rather than murdered him (and did so because he was a horrible fit for the kingdom and an out and out terrible father), and forgoes a relationship with Finn for the time being to focus on keeping her people in control for the sake of all the other kingdoms out there.
- Goo Goo Godlike: She was very powerful as a baby. To the point that her father had her abandoned in the wilderness in fear that she would become stronger than him and usurp the throne. He was right of course, but it was still a jerk move.
- Hair-Trigger Temper: Most noticeable immediately after being released from her lantern ("STOP WHISPERING!!!!" -> *baby Flambos*), but appears to be trying to work it out for Finn's sake. The "hair trigger" side of it gets less and less evident with each appearance, though she still has a temper.
- Kill It with Fire: Quite enthusiastic about resorting to immolation as a solution for her immediate problems. At the same time, she's only attacked direct threats ...so far.
- Kill It with Water: Hurt by anything that'll put out a fire, in fact (fire retardant, rain, water, tears, and simply stamping out a flame, as established in "Hot to the Touch"). She had gotten a little better at this by "Vault of Bones"; she lit a torch for Finn, and when he later doused it, didn't even react.
- Klingon Promotion: A more kid friendly variant. Since they obviously couldn't get away with a teenage girl killing her father to obtain the throne, Flame Princess instead stages a coup which results in the (now former) Flame King being trapped in Flame Princess's old lamp, while Flame Princess takes the throne and ascends to the rank of Queen.
- Linear Warriors, Quadratic Wizards: Clearly more powerful than Finn in "Vault of Bones", though they're still young enough that it's not fully clear where their limits are yet. And then there's her general lack of experience.
- Meaningful Name: Other than the obvious, she's Finn's new flame.
- Mind Screw: In her introductory episode, Jake tries to woo her on Finn's behalf (successfully), and then shapeshifts into Finn to continue the process. But when Flame Princess is said to be evil, he immediately recants. When the real Finn meets her, he first saves her, and then tells her he likes her. So, from Flame Princess's perspective, he told her he liked her, then didn't like her, then liked her again. Flame Princess' confusion is palpable, and her reaction perhaps predictable.
- Mood-Swinger: Goes from being sweet and kind in one moment to screaming at the top of her lungs the next. Largely tapers off as time passes.
Flame Princess: Come on, honey. Eat your soup.
Finn: Huh? Wait, wait, wait...
Flame Princess: EAT IT NOW!!!!note
- Mundane Utility: Can control her flames well enough to sense the composition of objects around her (or something), without damaging them: "I'll just use my Heat Sense." More to the point, the fact that she's made of flame means she's a walking light in dark places.
- The Noseless: She can still smell, though.
- Not Good With Rejection: To say that she doesn't take rejection well would be putting it lightly.
- Odd Friendship: In "Earth & Water", she befriends Cinnamon Bun. She likes him because he's honest, and this inspires her to make complete honesty the cornerstone of her rule once she takes the throne.
- One-Winged Angel: Can transform into a giant monster made of fire.
- Personality Powers: Her emotional state swayed her fire powers to a considerable degree, initially; even when she's happy she's destructive. In fact, too happy and she could cause the end of the world. She's been getting better about it.
- Person of Mass Destruction: It gets like ten times worse in each appearance before tapering off in her later appearances such as "Ignition Point", and isn't an issue at all in "Vault of Bones" (she's more aware of her abilities and appears to be trying to avoid falling under the trope, to the point that she no longer trails fire as she walks). She still backslides on occasion if sufficiently provoked, as she devastates the Ice Kingdom and nearly kills Ice King and Gunther in "Frost & Fire". It's also shown in "Earth & Water" that when she was a baby, she set an entire forest on fire merely by walking through it. Part of the reason for this is that she was prophesied to be far more powerful than her father.
Flame Princess: Fire's purpose is to burn. So I'm going to turn this land into my fire kingdom.
- Playing with Fire: Naturally. And literally. Skeet shooting with little fireballs appears to be a game for her.
- Power Incontinence: She apparently has to take special precautions to safely interact with non-Fire Kingdom residents, being living flame and all. Just to play cards with Finn for an extended period of time (in "Vault of Bones"), they have to cover her spot on the couch with foil, and wrap her hands in the same. However, since Jake is able to take her place immediately after she leaves, it's likely an extra precaution rather than a necessity.
- The Power of Love: One word can cause her flames to burn brightly, one drop can turn her completely around. If she gets romanced too much, she might destroy the world with her heat.
- Rebellious Princess: Keep her locked in a lamp, or she'll light up your life. And everyone else if she gets too excited. Though now it's evident that she's rebelling against her father (and nature as living flame) due to having been locked up like that.
- The Reveal: Flame Princess wasn't locked up because she was evil, Flame King locked her up because Princess Bubblegum had concluded that she was physically unstable and extreme romance would cause her to lose control of her elemental matrix, causing her to burn to the planet's core and destroy Earth in the process. A second one in "Earth & Water" reveals she was locked up because her dad attempted to abandon her in the woods to die as a baby after it was predicted she'd surpass him power-wise. However the attendant he sent to do so had a change of heart after playing with her for a bit and gave her to a foster dad whose house she accidently burned down, proceding to unintentionally take a large portion of the forest with her. Princess Bubblegum then noticed the flames and returned Flame Princess to her father, ordering him to contain her or she would, resulting in her life long imprisonment.
- Ring of Fire: When Finn is chasing her, she casts one of these.
- Sealed Evil in a Can: Her father was keeping her far away from the rest of the court inside a kerosene lamp-style glass globe at Princess Bubblegum's behest, partly due to her aforementioned ability to end the world, and partly to keep himself in power.
- Second Love: For Finn.
- Self-Fulfilling Prophecy: A messenger brought news to Flame King of his daughter being destined to grow extremely powerful. Fearing that she would one day usurp his position the way he did from the former Flame King, he sent her out into the wilderness to die. But she survived long enough to burn down a large stretch of land outside of the Candy Kingdom, gaining the attention of Princess Bubblegum and causing her to bring the infant Flame Princess right back into the Fire Kingdom with a warning that she should be sealed away. The Flame King constructed a large glass lamp and placed her in it, leaving her there for 15 years, until one day Jake arrived in the Fire Kingdom to find a new love interest for his heartbroken friend. After courting her, she is freed, and after a series of dates and a breakup, Flame Princess returned to take the throne from her father.
- She Is the King: Her guards refer to her as the "new Flame King" after overthrowing her father.
- Skilled, but Naive: Despite her immense power, she understands next to nothing of the world outside the Fire Kingdom. Seems to be improving at this.
- Spam Attack: Multiple tiny fireballs are rather ineffective against sealed Power Armor however.
- Spell My Name with an S: Once in a great while, her name will be spelled as "Fire Princess". It sort of makes sense, given that she's from the "Fire Kingdom".
- Star-Crossed Lovers: With Finn as of "Hot to the Touch". Finn cannot touch Flame Princess without getting hurt, unless she (read: her flames) is severely weakened (read: near death). By "Burning Low", he's learned to take the pain better, but still...
Flame Princess: ...You would defy nature for me?
- Superior Successor: According to a royal messenger, Flame Princess was destined to become far stronger than Flame King ever would, so he sent her out to die in the wilderness to die. Naturally he failed, and 15 years later she would indeed take the throne from him.
- That Makes Me Feel Angry: Initially has some trouble describing herself (she's pretty much an elemental rather than a typical denizen of Ooo in "Hot to the Touch"), but gradually gets better at it.
- Third Option Love Interest: Finn initially loved Princess Bubblegum and got along well with Marceline - but ended up with her, a sort of add-and-divide-by-two version of them in terms of personality.
- Took a Level in Kindness: Has mostly cooled down by "Ignition Point" by ceasing to be destructive (consciously). Now just chills around with Finn and Jake whenever she appears.
- Town Girls: The Neither to Bubblegum's Femme and Marceline's Butch.
- Tsundere: Oh, yes. In "Incendium", she blushed at the fact that Finn "likes" her, then immediately slapped him afterwards for his(from her viewpoint) waffling. In "Hot to the Touch", when she was warming up to Finn's declaration of love, she back-pedaled a few seconds later in disgust, saying that he shouldn't toy with her. Her unpredictable and fiery personality really help the trope come out. Not so much from "Ignition Point" onward; even after she and Finn break up in "Frost & Fire", she's more sad than angry.
- Uptown Girl: For Finn.
- Violently Protective Girlfriend: She becomes this in "Vault of Bones" when Finn gets captured by a giant Goo Skull. Thankfully, she's gotten a LOT more levelheaded by that point.
- Weaksauce Weakness: Water. This initially applied to any flames she'd made, but that appears to no longer be the case (she lit a torch for Finn at one point, which he then put out in water to no reaction from her).
- What the Hell, Hero?: She's less than pleased when she finds out Finn has been tricking her and Ice King into fighting each other. Especially because the last fight was sparked by a fake letter. Containing stuff about her only Finn would know.
- When All You Have Is a Hammer: As shown in "Vault of Bones", meticulous exploration bores her and she prefers to just burn her way through obstacles. Subverted when she uses Finn's method to free him from the coocoon, since burning up his captor would kill him, or at least greatly injure him.
- Woobie, Destroyer of Worlds: Averted. She certainly considered taking over Ooo with fire, first thing out of the Fire Kingdom, but Finn and Jake managed to prevent it. On top of that, she seems to have considered it an elemental imperative at the time, likely stemming from a childhood spent cooped up in a glass bottle...
- Wreathed in Flames: Is in fact living flame, and has a variety of fire attacks at her disposal. Can switch forms as well, but since she defaults to her humanoid appearance, it's probably this and not Elemental Shapeshifter.
- Yandere: Had shades of this, initially.
- You Wouldn't Like Me When I'm Angry: No, you wouldn't.
Flame Princess: You should not toy with the emotions of a fire elemental.
