    Princess Bubblegum 
http://static.tvtropes.org/pmwiki/pub/images/Bubblegum_7328.jpg
"Hurry, sweet citizens..."
Voiced by: Paige Moss (2006 pilot), Hynden Walch (the series)

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.


  • 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".
  • Affectionate Nickname: Finn sometimes calls her "Peebles", among others.
  • The Ageless: In "The Suitor," PB's suitors say they have been waiting for centuries. In the flashback of "Earth & Water" (fifteen years ago), PB still looks the same age.
  • Alliterative Name: Her proper name (thus far spoken only by Marceline) is Bonnibel Bubblegum.
  • Anthropomorphic Food: Her body is actually a mass of gum. In Princess Monster Wife, we get to see a cross-section of her head, and she has no physical brain. This is in contrast with Turtle Princess, where we can actually see her brain. See Blob Monster below.
  • Anti-Hero: She becomes this in later seasons. She does whatever she has to for the Candy Kingdom, but her devotion to being the best ruler possible makes her distrustful and emotionally cold, and she sometimes makes very morally dubious choices for what she considers the greater good, or engaging in sneaky political manoeuvring. Most recently it's been revealed that she constantly spies on the entire world, including her most loyal allies and servants.
  • Badass Adorable: Aww, look, how quirky and cute- Wait, is she firing lasers? AWESOME!
  • 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 in Charge: It's pretty easy to see why the Candy Kingdom is as peaceful as it is, with someone like her on the throne.
  • Berserk Button: Hurting those she cares about, especially Lady Rainicorn. Ricardio found this out the hard way.
    • In "Apple Wedding", we learned she does NOT tolerate having her authority questioned. (Specifically, if they claim if the "One True King of Ooo" has that authority.)
  • Better as Friends: With Finn. After various ups and down, Finn also settles for just being happy being friends with her.
    • On the other hand, "King Worm" and "The Lich" imply that Finn still harbors romantic feelings or bitterness for Princess Bubblegum. Hinted further when Finn was dealing with depresson over the loss of his arm in "Breezy" and it's the sight of her (along with what would be his next sword) that fills him with a loving warm feeling that causes his flower arm to sprout into a tree and getting his arm back. Furtherstill, his happy place as shown in Hero Heart is himself with Princess Bubblegumm or rather her younger self, showing he clearly still cares about her beyond platonically.
    • Then there's the fact how Finn is an emotional crutch for Princess Bubblegum and the uniqueness of their relationship. One could say they're Better as Friends since it allows Bonnibel to rule her kingdom without love as a distraction, but whether it's good for them is a different matter entirely.
  • 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.
    • Later episodes imply that she has been helping rebuild society in Ooo after the Great Mushroom War.
  • Big Brother Is Watching: She has extensive surveillance network throughout Ooo, reaching even neighboring kingdoms. At the end of "The Cooler" she takes it down, reminiscent of the scene from The Dark Knight where Lucius Fox destroyed their surveillance network.
  • Bi the Way: Word of Olivia confirmed that Bubblegum used to date Marcy.
  • Blob Monster: The pink goo in "Simon & Marcy" can easily be seen as proto-Bubblegum, but Word of God confirmed that such pink goo in one of the games is Bubblegum's parents. In "Bonnie and Neddy", it's revealed that she was originally part of a massive wad of gum that she refers to as "the Mother Gum"; she eventually broke away from it and over time she grew into what she is now.
  • 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.
    • There are things that can be guessed at. She is centuries old, but she has explicitly stated that she's not immortal. Considering she's also The Ageless, she may very well not be certain of how long her lifespan really is. Between that, how often she and/or the Candy Kingdom are in danger, and how incredibly high-maintenance the candy people are, it's not really surprising how desperate PB is to have either a competent successor or a way to stave off/undo death as soon as possible.
  • 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.
    • The season six finale sees her realize how much of a jerk she was to the candy people on top of losing her throne (aka her one purpose in life) to the King of Ooo.
    • "Bad Timing" reveals that she keeps cyanide pills in case her castle is attacked, and the events of the episode drive her to drink at the end.
    • "Something Big" implies that she's repressed so many negative emotions in order to keep herself and the kingdom going, that she's a walking well of raw emotional power, and a prime target for Maja.
  • 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.
    • Nearly subverted in the episode Too Young. She clearly is indulging her time being a younger girl free of the responsibilities of Princesshood. There are also plenty of moments between her and Finn and she even confesses on how she wishes to remain young with the implications of growing alongside Finn in a potentially romantic way. Of course, she chooses her kingdom (namely because Lemongrab is running it to the ground.)
  • 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. First mainly seen in the episode Too Young.
  • Character Development: In "The Cooler", she gets a What the Hell, Hero? speech from Flame Princess and after admitting she doesn't want to be considered a bad person, she stops her Sinister Surveillance. In "Pajama Wars" and later episodes of season six, as difficult as it is for her, she's also trying to mellow out and not be so controlling. After losing the throne, she realizes just how neglectful and controlling she was to her subjects and has started to mellow out more.
  • 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.She stopped wearing it when she lost the Candy Kingdom's throne to the King of Ooo, but she got it back after regaining her position.
  • 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.
  • Create Your Own Villain: Her creations have a bad habit of turning against her:
    • Goliad went power mad and has to be trapped in a psychic battle with another sphinx.
    • Lemongrab became a dangerous dictator, who had to be rebuilt to make himself stable.
    • And the biggest of all is her "Uncle" Gumbald. He's just as smart as she is — but infinitely more dangerous and with zero morals.
  • Cute and Psycho: She can be a bit crazy sometimes, but she's still ultimately on the side of good.
  • Cute Monster Girl: She's a very humanoid Candy Person, with most of the others looking like sweets or cakes with faces and limbs.
  • 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 only kidnapped by the Ice King when she doesn't have effective countermeasures on hand. When she does, she often 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 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.
  • Dude Magnet: She has Finn and Ice King (and possibly Marceline) vying for her affections, along with all the wizards competing for her kiss in "Wizard Battle" and all the suitors in "The Suitor" (which reveals that at least one Candy Kingdom family have been trying to court her for generations). Lumpy Space Princess points this out in "Bad Timing" and is furious, because while LSP tries to be this PB succeeds without any apparent effort, and isn't interested in any of them.
  • Dude, Where's My Respect?: She gets plenty of worship and romantic attention, but not a whole lot of respect. Comes to a head in "Apple Wedding", where everyone immediately views the King Of Ooo a complete fraud as having more authority than her and she rages so much that she nearly ruins the whole wedding.
  • Elemental Embodiment: She is the embodiment of Candy, one of Ooo's four elements, the others being Fire, Ice, and Slime. She learns in "Elementals" that she can shoot candy out of her hands.
  • Emperor Scientist: She's the ruler of Ooo whose power seems to be from the fact that she made most of her candy subjects. (And can make replacements, if necessary.)
  • Face–Heel Turn: Came dangerously close to turning into a full-on Big Bad at several points in Seasons 5 and 6. Fortunately, she was reined in by Flame Princess in "The Cooler".
  • Failure Is the Only Option: Bubblegum makes it clear that she would gladly give up being ruler of the Candy Kingdom because of how demanding the job is. Unfortunately when she has actually stepped down she is shown as lost and longing for it back, both because she has already devoted almost the entirety of her life to it and because her successors are inadequate. So she either keeps at a job she doesn't want or finds herself without purpose.
  • 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.
  • First-Name Basis: At least some people have started calling her Bonnie after she lost her throne to the King of Ooo.
  • For Science!: She does most of her explots for science when it's not diplomacy or just hanging out.
  • 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. She sometimes breaks into it when surprised or worried.
  • Growing Up Sucks: She tells Finn that she would rather stay 13 than turn 18 again and have to deal with the responsibilities that come with being an adult ruler.
  • Heel Realization: After Season Five ramped up her less than desirable traits, Season Six had her realize the error of her ways, with Season Seven being her redemption.
  • 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. The fact that she literally created them adds to this.
    • However, this seems to wane in later seasons, where we see some of her subjects resent her Big Brother ways, culminating in electing King of Ooo as their new ruler. Luckily she eventually wins her throne back by Season 7.
  • Hypocritical Heartwarming: As much of a schmuck as Lemongrab is, he's still her schmuck, darn it!
  • I Didn't Mean to Turn You On: She is clearly aware of Finn's infatuation with her in the beginning, but only wishes to have a courtly friendship with him. However, after the first battle with the Lich resulted in her becoming 13 years old (physically and mentally), she becomes quite attached to her hero and much more openly affectionate (not to mention more honest). However, she dismisses these moments as "that was five years ago" when she turns back to normal. Then there's this moment from Burning Low, where she thinks Jake listened to her about Flame Princess, but Jake interpreted it differently and told Finn she's jealous. Then there's this line (referring to how Finn being with FP is dangerous because the intense emotions could cause FP's power to go out of control), but Finn (and the audience) understandably interprets this differently:
    Princess Bubblegum: Finn, sometimes you want someone and you want to kiss them, and be with them. But you can't, because responsibility demands sacrifice.
    Finn: What are you trying to say?!
    Princess Bubblegum: I'm trying to say that you're a hero, Finn. You're my hero.
    • After this episode, it appears that she does not have any romantic feelings for Finn, but her tendency to bottle her emotions for the sake of her kingdom along with her secretive nature means she could be lying to Finn about her feelings or even to herself. She views love as a distraction toward ruling her kingdom so abstains from it, so it is unknown how she really feels about him.
  • 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.
    • Season 5 throws a lot of this her way. She almost always has a good (or at least plausible) reason for everything she does, but she's not above making sacrifices.
  • 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.
  • I Need a Freaking Drink: After she sends Lumpy Space Princess back to a form before she met her true love (who was accidentally erased from existence), she sighs and pours herself a glass of root beer.
  • 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.
  • Jack Bauer Interrogation Technique: Did this to the Ice King in "Wizards Only, Fools."
  • Jumping Off the Slippery Slope: Subverted in "Rattleballs" when she makes it look like she destroyed Rattleballs.
    • Comes close to it in "The Cooler", but has a Heel Realization thanks to Flame Princess and backs off from the slope as a result.
  • Last-Name Basis: No one (apart from Marceline) calls her Bonnibel.
  • Lawful Good: In-universe-assigned alignment in the comic series.
  • Living Emotional Crutch: She is this to her brother, Neddy, a candy dragon. Unlike his sister, he is very sensitive, docile and is quite fearful of the outside world (implied due to his first experience after being born being pain). As such, she is the only person who can comfort him and who he feels comfortable with the most part.
    • It is heavily implied she has one of her own through her champion, Finn. She cares a lot about him and while they're friends, this aspect of how he keeps her grounded and positive may be signs she cares for him than she is willing to admit (as noted by her tendency to bottle her emotions.)
  • 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. " As of "Too Old" and "Lemonhope Part 1 and 2", how well this applies to the way she views the Lemongrabs is questionable.
  • 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.
  • My God, What Have I Done?: "Nemesis" strongly implies that her I Did What I Had to Do tendencies are freaking even her out, as she's awkward when asked about the rattleballs robots, and she thinks she's the evil one Peace Master is looking for. She's not, it's Peppermint Butler.
  • Necessary Evil: Hynden Walch describes her as a "selflessly evil" character, since she wants to do good and stabilize the land of Ooo, but unfortunately her methods of doing so border on dictatorship. Following "The Cooler", she has begun to move away from this.
  • Nerds Are Sexy: Again, at least according to Finn. Even if he doesn't admit it.
  • The Noseless: Like most people in Ooo. she lacks a visible nose.
  • No Respect Girl: She was the one who created the Candy Kingdom and the majority of the candy people, so is angry when the King Of Ooo waltzes in out of nowhere, is proven to be a fraud and her subjects would still rather obey him than her just because he has a higher title.
  • Nice Girl: Most of the time, Bubblegum is a sweet-natured, kind girl. Unfortunately, it's layered with deep-suited trauma, dishonest tendencies and her insistence in trying to bring order to Ooo.
  • Odd Name Out: She's the only princess in the series whose name doesn't follow the "(Descriptive Noun) Princess" formula. (There's also Princess Business, but she's only mentioned, never shown.)
  • Out-of-Character Moment: Bubblegum is usually a Damsel out of Distress, saving herself or at least angry that she's in peril. Which is why it's weird in James II where she's just standing in the same place scared when Zombie!James menaces her, thus letting the other James save her and prove himself.
  • 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: A major Fatal Flaw of hers. 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 degrades and derides their beliefs about magic, and thus gets herself, Finn, Jake, and Abracadaniel thrown in Wizard Prison.
  • Pragmatic Hero: Don't let first impressions fool you: she's willing to stoop pretty low in various situations.
  • Pretty Princess Powerhouse: Princess Bubblegum is prim, proper, poised, very pink and also one of the best defenses that her kingdom has. She also singlehandedly defeated Ricardio, even when he hurts Lady Rainicorn. Even Finn, her champion, occasionally needs her to bail him out of trouble.
  • 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: Note that she does have other outfits, several of which aren't very pink - the ones she wears as Princess are all pink-ish.
  • Rapunzel Hair: She's a princess so it goes down to her knees (when she has it down).
  • Really 700 Years Old:
    • She's at least 300. In the game Adventure Time: Explore the Dungeon Because I DON'T KNOW!, she tells the Ice King that she's 827 years old.
    • In "The Suitor", it's revealed PB's various suitors have been waiting to court her for hundreds of years.
    • It's been demonstrated via flashback that scales back centuries (and finally outright acknowledged by Finn) as of "The Vault".
      Finn: PB, you are like a bazillion years old! You're not freaking 19! What the heck?!
      PB: (embarrassed) Hahaha...
      Finn: Weirdo.
  • Realpolitik: Has been steadily getting more willing to keep tabs on everyone, and is willing to directly sabotage other kingdoms (particularly the Fire Kingdom) to maintain peace. However, she also emphasizes using peaceful means first, only stepping up to more violent methods when those have failed.
  • Rose-Haired Sweetie: She's a sweet princess most of the time.
  • Royals Who Actually Do Something: May actually be the most active of all the Princesses in Ooo. Not that the bar is set terribly high; the only other princesses who seem to do anything other than "exist" are Turtle Princess, who is a librarian, Lumpy Space Princess, who is basically a hobo and occasionally picks up odd jobs (like being an "adventure secretary"/"writer" in "Gotcha!"). The only other princess with a decent track record of doing stuff is Fire Princess, who threatened Candy Kingdom, adventured with Finn, and usurped her father and turned Fire Kingdom's Card-Carrying Villain nature around.
  • Rubber Woman: Far more downplayed than Jake, but in "Have You Seen The Muffin Mess", when the plague cuts off her arm, she can stretch her bubblegum self into a new one with fingers.
  • Sanity Slippage: PB's been getting more and more... stressed... over the course of the series.
  • 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.
  • Screw the Rules, I Make Them!: Experimenting on living creatures? Creating new life from your friend's DNA without asking? Preemptively destroying other kingdom's forces? Dictating her subject's lives to the point of who marries who? Hating someone for eating pudding? Sending your hero off to beat the snot out someone for the greater good? Don't worry, it's fine. It doesn't really matter how questionable her activities are, because Princess Bubblegum is the sole ruler of the Candy Kingdom. She gets to do what she wants, no matter how morally questionable. Though she is sometimes persuaded by her friends to stop certain behaviors, there's nothing making her do anything.
  • Sherlock Scan: Bubblegum is shown to have this ability in "Sky Witch"
  • Sinister Surveillance: She admits that she spies on everybody in "The Cooler", and doesn't find it to be an issue that people are disturbed by this. By the end of the episode, she seems to get the hint, and unplugs her entire secret surveillance system and locks up the door.
  • The Smart Girl: She's very skilled when it comes to scientific matters.
  • The Sociopath: Rebecca Sugar described her as such, though clarified that she wasn't a literal example and more a case of someone trying to be like one, suppressing emotions and empathy for what they perceive to be the greater good. Starting with Season Six, she's started to change upon realizing how unhealthy this way of living is.
  • 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. 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.
  • Stereotype Flip: Of Princess Classic. She's so pink she's bubblegum, with a modest pink dress and Rapunzel Hair as her default look, but she's actually a Broken Bird workaholic who'll protect her kingdom no matter what the cost and keeps cyanide pills in her meeting room.
  • Surrounded by Idiots: Most of her subjects are pretty dumb. Turns out she made them that way to ensure their loyalty,and also because they appear to be a lot happier as such. Whenever they become intelligent rational beings, they tend to be treacherous jerkasses.
  • 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:
  • Treehouse of Fun: Her castle is built around a tree.
  • 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 the romance (barring Finn most of the time).
    • 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.
  • Well-Intentioned Extremist: She's been shown as willing to pull drastic action if she believes it will aid her citizens. Flame Princess calls her out on this in "The Cooler". Something that PB seems to take to heart.
  • What Measure Is a Non-Human?: Considers her subjects expendable, as she can make more. She has prevented Finn from sacrificing himself and allowed a candy subject to do so because of this specifically.
  • 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.
  • You Gotta Have Blue Hair: Has pink hair. Justified since she's made of bubble gum (if it even is hair at all).

    The Grass Sword/Fern 
http://static.tvtropes.org/pmwiki/pub/images/grass_sword.png
Click here to see its new form as Fern 
Voiced by: Hayden Ezzy (as Fern), Brad Neely (as the Green Knight)
A cursed sword made of grass provided to Finn by the Grassy Wizard. It cannot be removed, but becomes controllable once Finn accepts it as his weapon. As of season 7 episode "Reboot", it detaches itself from Finn and merges with the Finn Sword, becoming its own person.

  • Absurdly Sharp Blade: Sharp enough to slice through metal, and incredibly precise.
  • Adaptive Ability: It reacts to Finn's intense desire to not let his father escape in "Escape from the Citadel", taking over his whole arm, swelling up enormously, and giving him enough strength to restrain an asteroid from taking off. Unfortunately, the force of the asteroid's departure was so great that it ripped Finn's arm off; even then, the grass sword somehow made it so that the stump was completely healed over at the moment his arm was ripped off.
  • Alternate Self: Fern is a hybrid of the Grass Sword and the version of Finn that became a sword via time paradox.
  • Always Second Best: Fern's insecurities make him feel this way about Finn.
  • Ambiguously Evil: Though it did at one early point attempt to overwhelm Finn, the majority of the time it seems to act in his interest even when acting without his permission.
  • An Axe to Grind: Fern's Weapon of Choice after he becomes the Green Knight. It can also turn into a snake.
  • Audible Sharpness: Rings like a bell when swung.
  • Came Back Strong: As the Green Knight.
  • Cool Sword: A tachi made of grass that's supernaturally sharp and deft.
  • Clothes Make the Superman: It's a curse yet it actually gives Finn enough skill to cut through almost anything, enough to fend off the Bandit Princess, who was in possession of the Finn sword that doubles the strength of the user.
  • Cursed with Awesome: A parody of it. The sword was meant to be an actual curse to the user who finds it unwieldy and fears it. Guess what happens next.
  • The Dragon: To Gumbald.
  • Emergency Weapon: Becomes the available second after the existence of the Finn sword, in case the Finn sword gets either stolen or broken.
  • Empathic Weapon: It responds to Finn's will, retracting to wrap around his arm when not in use. It also seems to possess some concern for Finn's safety, slapping him awake when he's unconscious in the ocean. It also destroys the Fear Feaster as he antagonizes Finn.
  • Evil Weapon: Implicitly, but Finn manages to keep it under his control. Played straight when Fern does a Face–Heel Turn.
  • Face–Heel Turn: After so many failures as a hero, he snaps and attempts to pull a Kill and Replace on Finn.
  • Failure Hero: Blames himself after failing to protect Ooo from the elemental curse and stopping the Lich's Hand plan during the entirety of "Whispers". This results in... well, see the trope above.
  • Fusion Dance: Fern is the result of the Grass Sword and Finn Sword, itself a version of Finn, merging into a single being. The result is someone with Finn's memories, the Grass Sword's abilities and mix of both in personality.
  • Kill and Replace: His goal is to be the only Finn on Ooo.
  • Living Weapon: Definitely alive, and possessing some level of sapience.
  • Ludicrous Melee Accuracy: Remarkably agile and the blade itself is flexible. It tends to carve solid objects into busts of Finn's head that themselves fall into separate pieces (i.e. the face and eyeholes slide out).
  • Mid-Season Upgrade: The sword itself has shown much more spotlight than any of the swords that Finn had in the entirety of the show and it proves more than enough to consider its keep on Finn. In the end of "Reboot", it detaches itself from Finn and taking his arm with it while protecting him from a rogue Susan Strong, merges with the Finn Sword and becomes Fern.
    • This happens again when Gumbald turns Fern into the Green Knight, allowing him to overpower Finn during the arm wrestling match in "Seventeen."
  • Only Mostly Dead: In the season six premiere, it's reduced to a flower on Finn's arm. A few episodes later, it regrows Finn's arm and is reduced to a thorn in the process. In the season finale, it grows back again, fusing with his regrown arm.
    • This happens once again when Finn accidentaly kills Fern in "Three Buckets."
  • Paradox Person: Fern's main consciousness is the Finn Sword, who was the result of Finn encountering his past self while trying to revive Prismo. He ended up turning into a sword before merging with the Grass Sword.
  • Stealth Pun: Hardly "stealth" since it's the name of its introductory episode, but it's literally a blade of grass.
  • Talk to the Fist: Or blade, rather. It manages to slice through the Fear Feaster, much to his surprise, possibly without Finn commanding it to.
  • Walking Spoiler: Its very existence on Finn's arm already concludes the (possible) final fate of Finn's missing limb conundrum.
    • This also applies to Fern's entire existence.

    Lady Rainicorn 
http://static.tvtropes.org/pmwiki/pub/images/1ATLadyRainicornLook_9694.png
"이게 더 좋아?" note 
Voiced by: Dee Bradley Baker (2006 pilot), Niki Yang (the series)

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 (and on occasion, not-so-innocently) flirtatious with Jake in public.
  • Cool Pet: 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.
  • His 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.
  • Intangibility: 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.
  • No Sense of Humor: At least when it comes to knock-knock jokes. We don't know what she said in "My Two Favorite People", but Jake tells Finn it wasn't "Who's there?".
  • 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.
  • O.O.C. 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. In the pilot, she only communicated in a series of burbling sounds; in the series, she speaks korean.

    BMO 
http://static.tvtropes.org/pmwiki/pub/images/bmo_786.png
"Who wants to play video games?"
Voiced by: Niki Yang

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, Macintosh 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.
  • 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.
    • The WonderCon Q&A panel confirmed that BMO is genderfluid, and both male and female pronouns apply.
    • In the Munchkin Adventure Time board game, every character has a card with two sides, depicting the normal character and genderbent Fionna and Cake counterpart (as in Munchkin, your character's STARTING gender is the same as your own). While BMO's card has two sides and two different pictures, no gender can be derived from them and his card outright states that BMO outright ignores any gender-related stuff in the game.
  • Animate Inanimate Object: She's a living video game console.
  • Become a Real Boy: Or it wants to, anyway.
  • Breakout Character: Has had a couple of limelight episodes, in fact.
  • Bi the Way: Regardless of his/her gender, s/he has shown interest in characters of both genders (a female chicken and a male bubble).
  • 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 his two episodes "BMO Noire" and "BMO Lost". Her 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 she 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 he 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...
    • In "James Baxter the Horse," BMO sings about being pregnant, carrying around an egg. A butterfly knocks the egg out of BMO's grasp, it shatters on the ground, and BMO starts crying. Wow...
  • Cloud Cuckoolander: As evidenced in the kinds of games he creates, such as an Abraham Lincoln fighting game and "Conversation Parade". Also has a bizarre imagination.
    • Also, in BMO Noire, it was implied that BMO is schizophrenic. There is one montage of clips, presented to him via dream sequence, showing him setting up the crime scenario, yet he does not adress this and apparently has no memory of doing so.
      • Also implied in "Five Short Graybles," were BMO is shown having a conversation with his reflection, naming him "Football."
  • Covert Pervert: She 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 she 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. BMO can't actually eat anything, but tries anyway.
  • 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".
    BMO: "I feel like I was hit with a Dracula by King Kong".
  • Massive Numbered Siblings: While unique, BMO's creator made a large number of other Mos, who recognize BMO as family.
  • Meaningful Name: Mo revealed BMO is short for Be More.
  • Mirror Monologue: Only in the graybles so far.
  • Mr. Imagination: Takes it to really bizarre heights.
  • No Biological Sex: Since she's a robot, she isn't programmed with sex protocols.
  • Phantom Zone: It's only ever been seen in one episode so far.
  • Retraux: Crosses over into this, as BMO 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 par for the course.
    BMO: If anyone tries to hurt Finn, I will kill them!
    Jake: ...Okay, good.
  • Split Personality: Football may or may not be this to BMO.
  • Talking Appliance Sidekick: More of a supporting character than "sidekick" but it still counts.
  • Tagalong Kid: While certainly not a kid in the conventional sense, he'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.
  • Tin Man: In "Donny", Beemo states how as a machine she can not feel pain or emotion but states that it very much hates Donny.

    Lumpy Space Princess 
http://static.tvtropes.org/pmwiki/pub/images/lumpy_space_princess_1651.jpg
"Whatever!"
Voiced by: Pendleton Ward

A purple, floating Lumpy-thing with a star on her head and a pushy attitude. Also, she's apparently Latina.
  • Attention Whore: She crashes Tree Trunk's wedding dressed in a wedding gown of her own, saying that everyone is ready to pay attention to her.
  • Big "NO!": Played for Laughs when Finn and Jake spill her beans in "Heat Signature".
  • Bratty Teenage Daughter: To her parents.
  • Character Development: For a long time she'd run away from her parents in a rather immature fit of rebelliousness, being too contrary to admit she couldn't handle the rough life. After Finn and Jake help her reconcile with her parents, however, Word of God indicates that she had discovered a love of nature and the independent life and now spends a lot of time living in the woods (hence her appearance in "Gotcha") while being on good terms with her parents. "Gotcha!" also establishes that LSP is now a published writer.
  • Cloud Cuckoolander: She comes from a whole realm of these, and often breaks out into party mode at random intervals.
  • Drama Queen: No further explanation needed.
  • Element Number Five: Lumps takes this role in Ooo's elemental cosmology, making her immune to the elemental kingdoms in the Elements mini-series and allowing her to fix things.
  • Everyone Calls Him "Barkeep": LSP for short. It also happens to serve as a formal title (she's the princess of Lumpy Space) and as a description of her (she's a space princess, and she's really lumpy).
  • Forgetful Jones: She can be ridiculously forgetful at times. In "Video Makers" after Jake tells her they're filming a food fight scene she immediately forgets they're filming a scene and gets mad when Peppermint Butler throws food at her.
  • Gonky Femme: She doesn't look or sounds remotely feminine, but is a stereotypical valley girl nevertheless.
  • Hidden Depths: As of "Gotcha", it would seem that LSP actually enjoys the homeless life. She's also apparently a pretty good writer.
  • Honey Trap: Tries to seduce Finn with her lumps so she could write a book.
  • Interspecies Romance: Her crush on Finn, which sparked after her ex broke up with her.
  • Jerk with a Heart of Gold: She can be a tad hard to get along with at times and tends to be self centered as a byproduct of being a Lumpy Space individual (Finn and Jake came down with similar personalities when they turned Lumpy), but she's really not that bad a person deep down and genuinely considers Finn and Jake her friends.
  • Karma Houdini: Has a tendency to become violent when she doesn't get her way. She's also accidentally banished someone to another dimension, almost burned down the Candy Kingdom, and may or may not have raped Finn while he was physically and emotionally compromised.
  • Large Ham: For joke purposes.
    LSP: MY HEART HURTS BECAUSE I FELL OUT OF LOVE!!
  • Lovable Alpha Bitch: She has a lot of issues and jerkass moments, but she's endearing and sometimes means well at least.
  • No-Sell: In the Elements mini-series, the conversion that results from exposure to the elemental kingdoms doesn't affect her at all. This is because of the nature of lumps in the elemental cosmology.
  • Plucky Comic Relief: She's often a source of comic relief, even though she's got darker herself in season five/six times.
  • Precocious Crush: Inverted. She's 15, but has a crush(?) on 13-year-old Finn.
  • Phoneaholic Teenager: She is constantly gossiping through her mobile phone even though she's homeless and living in a forest, on canned beans.
  • The Runaway: Sometime before "To Cut a Woman's Hair" she ran away into the forest and still lives there as of "Heat Signature". She returns home in "The Monster". In "Gotcha" she's once again roughing it, but apparently only because she wants to and is still on good terms with her parents.
  • Shipper on Deck: The Elements miniseries hints that she, while having a small interest in Finn, genuinely believes that he and Fire Princess should be together. At one point where Finn and a maddened and empowered Flame Princess start fighting, she casually mentions while watching the fight that she could still picture the two together. In "Happy Warrior", she makes various comments attempting to get out of Finn the answer that he is still interested in FP and doesn't buy that he is genuinely proud of their friendship.
  • Silicon-Based Life: Lumpy Space people are made of irradiated stardust.
  • Speaks Fluent Animal: Part of the reason why she was able to survive in the wilderness for as long as she did is because she can understand what animals are saying through their body language. Or at the very least, she thinks she can.
  • Spear Counterpart: Lumpy Space Prince. Amusingly, and unlike the other counterparts, they have the exact same voice.
  • Suddenly Ethnicity: Apparently LSP's Latina. She had a Quinceañera in "The Eyes".
  • Thinks Like a Romance Novel: Or a teen drama. Borders on Blue and Orange Morality at times.
  • Took a Level in Jerkass: In season five and six, she tried to burn down the candy kingdom out of perceived jealousy and had a grey-consenting make-out session with Finn. She seems to realize this though, and "Be Sweet" demonstrates some serious self-loathing.
  • Valley Girl: With a deep, grunting valley girl accent at that. It doesn't help that all of the Lumpy Space people speak like that.
  • Vocal Dissonance: Her voice is very masculine, to say the least.
  • World-Healing Wave: When given Ice King's crown and the elemental jewels from PB, Flame Princess and Slime Princess, she's able to undo the elemental transformations and restore the world to normal.

    Marceline the Vampire Queen 
http://static.tvtropes.org/pmwiki/pub/images/marceline_the_vampire_queen.png
"Dang, man, I didn't think you'd ever catch on!"
Voiced by: Olivia Olson and Ava Acres (as young Marcy), and Cloris Leachman as the elderly Marceline in the Farmworld universe

The queen of the vampires by default as she killed all the other vampires, including the king. 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.
  • Action Girl: She can definitely handle herself in wild situations. Although her lazy side makes it so she doesn't get to show it off much.
  • 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".
  • All-Powerful Bystander: As one of the most powerful creatures in Ooo, she could easily defeat almost any other character in the show especially if she started eating souls and stealing powers, but she prefers to either stand back and watch, or simply ignore everything.
  • Amazon Chaser: Shows very obvious signs of attraction to Susan Strong in the Islands mini-series.
  • And Then John Was a Zombie: She used to hunt vampires, even dedicating herself to wiping them all out, but was turned while taking down the Vampire King and his minions.
  • 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. She also begins transforming into this state when extremely hungry.
  • Bare Your Midriff: In the Stakes miniseries.
  • Berserk Button: A few, but most notably stealing or mocking Hambo or Ice King in any way is a good way to get on her bad side.
  • Bi the Way: She has been shown in a relationship with the male Ash, but Olivia Olson, the character's voice actress, confirmed that Marceline and Princess Bubblegum used to date. She also showed obvious attraction to Susan Strong when they met.
  • Breakout Character: Marceline started as a somewhat more prominent than normal secondary character. Although she doesn't appear in many more episodes that she originally did, she has more or less became a main character. She got her own 8-part miniseries exploring her past in the seventh season.
  • 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.
  • Brought Down to Badass: When her vampire essence was removed, she reverted back into half-demon with soul stealing abilities.
  • Cannibalism Superpower: She got her wide variety of powers by eating the souls of other vampires who previously possessed them.
  • Chaotic Neutral: In-universe-assigned alignment in the comic series.
  • 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'?"
  • Combo Platter Powers: Has a large and varied set of abilities and an ability to easily get more
  • Companion Cube: Her childhood teddy bear, Hambo, mainly because it was given to her by her father figure and best friend Simon Petrikov. It was sold to Maja the Sky Witch by her Bastard Boyfriend Ash, causing them to break up, although she reclaims it in the episode Sky Witch. Only to lose it again in an effort to help Simon say goodbye to his lost love in Betty.
  • Cool Big Sis: She occasionally acts like this toward Finn.
  • 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 Little Fangs: Though it's fairly clear that her entire mouth is full of sharp teeth.
  • 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.
  • Daywalking Vampire: Direct sunlight can still burn or even kill Marceline, but things as minor as a shaded hat or sunscreen can protect her. Her Healing Factor can also quickly reverse minor damage from the sun, which isn't surprising considering the vamp she got the power from could totally ignore sunlight.
  • Eerie Pale-Skinned Brunette: Refer to her page image. And yes, she can get really creepy when she wants.
  • Et Tu, Brute?: Almost everybody Marceline has ever loved has either betrayed her and/or abandoned her. Following her mother's death, she was raised by the Ice King, who became a father figure to her during the early days of the apocalypse, but he doesn't remember his past with her due to his insanity. After that, communication with her birth father is infrequent and often results in him hurting her feelings. Later, a boyfriend steals and sells her stuffed bear, the only memento she had of her days with Simon. Finally, she had a major fallout with Princess Bubblegum, who may or may not have been her girlfriend in the past. As a result, she has a tendency to bottle up her emotions and drive others away before they can get close to her.
  • 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. She's the Vampire Queen, and she can be unpleasant, but is nice mostly.
  • Goth Girls Know Magic: She's a Perky Goth with a punk rock style, and has supernatural powers as a vampire and demon.
  • Half-Human Hybrid: Half-demon, half-human, 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 is hanging out at her house playing music with her and they 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 due to her general apathy. And in some situations, she's either outclassed by the threat (facing her father) or some supernatural rule prevents her from doing much.
  • Human Mom, Non-Human Dad: A soul-sucking demon of a father who rules the Nightosphere in contrast to her mother who is just an ordinary human.
  • 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 unsuccessfully 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. She acknowledges this in Stakes, and thinks she can only move on with her life if she starts aging.
  • Immortality Begins at 20: Zig-zagged; she appears to have aged at a human-like rate until young adulthood, then slowed down from there because being half-demon made her naturally Long-Lived. She only fully stopped aging when she became a vampire—the fact that she was physically in her late teens or early twenties was just a coincidence.
  • Important Haircut: Signifying her depression and wanting to grow up, Stakes cuts her Rapunzel Hair short.
  • 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 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 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 Joking" Justification: During her more dickheaded early days in show, she leads Finn on a massive mind scarring prank day as her minion. Though he takes it in good stride when he finds out.
  • The Lad-ette: Clearly demonstrated (in a kid-friendly way) through her willingness to fight everyone and everything, in the same way that Finn does. Not to mention several episodes clearly demonstrate her lack of appreciation for hygiene, whether it be her picking her nose, not washing her hands, or remarking that her armpits stink.
  • Last of Her Kind: Although non-canon comics show other vampires, the show eventually establishes her as the last vampire on Earth. It's revealed that she killed all of the others, and the last one made her into a vampire in the instant he was dying.
  • Lead Bassist: Marceline's bass often accompanies her when she sings, making her a Type B.
  • Like Brother and Sister: With Finn. 'Go With Me' confirms that neither of them have feelings for each other that way.
  • Living Forever Is Awesome: Of the two immortal characters, she's the one that has the most fun. Subverted in "Stakes", when she believes her lack of aging is keeping her from solving her personal problems, and tries to get it taken away.
  • Long-Lived: 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.
  • Looks Like Orlok: When she gets too hungry, as seen in Red Starved. She also makes her nose look more bat-like when she wants to pick it.
  • Morality Pet: Even a thousand years later, Simon/Ice King still cares about her, even if he can't remember why, and she's notably one of the few characters he's actually cared when he believed they were hurt.
  • Mundane Utility: She uses her powers whenever convenient.
  • Necromancer: "Corpses buried in mud that's black, from death I command you to come BACK!" She did it to throw a party.
  • Nightmare Face: Marceline can do this voluntarily and to great effect. In "Henchmen", she just does it for the reaction on Jake's face, as he is still afraid of vampires. The Adventure Time Team's portion of Frederator blog has a small collection of the faces she made throughout the episode.
  • Noble Demon: Noted by Finn in her second episode, she releases him from being her minion as it's "not as fun when they realize it."
    • She and Lumpy Space Princess raise havoc in Breakfast Princess' place, stealing her things, vandalizing the castle, and assaulting the guards, but they do draw the line at killing them, being visibly relieved when the guy they pushed through a high improvised window landed in something soft.
  • The Noseless: Like the other humanoids. Though she can morph a nose when she wants to smell something or pick it. This carries over to the Farmworld, where she appears to be the only denizen without one.
  • Not a Date: Goes to watch a movie with Finn in "Go With Me", both insisting it's not a date.
  • Not So Stoic: Under her cool and trickster-like demeanor lies a sensitive girl that will cry easily if the right buttons are pushed. (Pissing her off is still a no-no.)
  • Odd Friendship: With Finn, which doubles as an extreme form of an Intergenerational Friendship. Later on she's befriended Jake (though she likes to scare him) and appears to have had one with Bubblegum in the past, though Finn seems to have helped her and Bubblegum patch things up.
  • One-Winged Angel: She often employs this in a serious fight (or when she's trying to scare people), and one of the most memorable is a giant, bat-like creature.
  • Our Demons Are Different: She is a half-demon, with the demon half from her father's side. Appearently, it's reponsible for her unique anatomy, such the white skin, the fangs, and the pointy ears, since she only became a vampire when she was a teenager, and young Marceline already had said traits. It also doesn't influence her morality much.
  • Out of Focus: Does not receive as much screentime in season 6 compared to previous seasons, having only one episode featured on her ("Princess Day") along with a couple of minor appearances. Previous seasons features her at least twice per season. Season 7 reversed this and gives her much more screentime including the eight-part miniseries Stakes.
  • Our Vampires Are Different: Marceline claims that she sometimes drinks blood, but only because it's red, and she mainly "eats" shades of red, and sleeps in a normal bed instead of a coffin. Other vampires could just eat red, but they didn't want to which is why she killed them before even becoming a vampire herself. Sunlight and garlic aren't instantly fatal, but they still hurt like a mother. As long as she takes precautions not to be struck directly by sunlight (generally by wearing a sunhat or, more often, a parasol), she can be active at any time of day. All of her abilities come from vampirism except the soul-sucking power that let her absorb those powers from other vampires.
  • Pointy Ears: Comes from being half-demon, assuming her father is an appropriate representation of demons.
  • The Quincy Punk: Slightly; she's a wild and reckless sort of person, but Ooo in general doesn't seem to find her particularily dangerous. She seems to like the aesthetic more than anything.
  • Rapunzel Hair: Just look at her; it goes down to her ankles, though she cuts it short later in the series.
  • Really 700 Years Old: The show reveals she is over a thousand years old. However her childhood is still After the End, if less so than the current show. It's unclear whether she lived through the Mushroom War or directly afterwards. In "Simon and Marcy", set 996 years earlier, Simon mentions that she's 7, making her 1003.
    • If the only deviation between the main universe and Farmworld is that Simon stopped the Mushroom Bomb, then she must have lived through it, because she refers to him as her friend, meaning she must have met him before in that timeline and therefore in both timelines. That would also place the flashback of the meeting in "I Remember You" before the Mushroom Bomb fell, which validates the theory that the Mushroom War began as a conventional conflict and then escalated.
  • Red Eyes! Take Warning: Does this when she gets upset. Usually an extremely bad sign for whomever made her upset.
  • Sad Clown: Unfortunately she sings from the soul and gets upset when she notices she's let her defenses down.
    Marceline: How can- anyone relate to me? When they cannot see what I see- My vampire eyes see... only blood red- skies. Blood red skies make tears inside that I always hide.
  • Sense Freak: When she briefly became mortal again, she gorged herself on non-red food.
  • Sour Outside, Sad Inside: She drives people away out of fear of being abandoned and betrayed again.
  • Spear Counterpart: Marshall Lee. Though, because his only characterization came from when when Marceline's was telling a Fionna and Cake story - that is, she's describing him and how he would act - he ends up coming off to the viewer as a self-deprecating parody of her.
  • Sudden Anatomy: In "Marceline's Closet," she grows a pair of bat-like nostrils when trying to sniff out Finn and Jake.
  • Superpower Lottery: She has an enormous list of supernatural abilities. Though, it wasn't so much a lottery, as she had to earn every single one of her various vampiric powers.
  • Tank-Top Tomboy: Over half her costumes have involved tank tops, and she has all the tomboy characteristics.
  • Telekinesis: Briefly uses some on Finn in "Henchman", curling his arms so he can't interfere with her pranking. It's unclear if it's a demon or vampire power, but the affected object glows red.
  • Tomboy and Girly Girl: Tomboy to Princess Bubblegum's Girly Girl.
  • Tomboy with a Girly Streak: She does wear dresses and fairly pretty blouses on occasion.
  • The Trickster: Generally only in the sense of the way she interacts with people. When she actually gets into a combat-type situation, she prefers a more upfront approach.
  • Troll: Finds a lot of joy in screwing with people in general and Finn in particular, though she seems to draw her limits at actual physical harm, at least lately.
  • Tsundere: Shows quite a few signs of being one to her friends in general, and very strongly suggested to be one in "What Was Missing".
  • The Ugly Guy's Hot Daughter: Applies in the traditional fashion.
  • The Undead: She is a vampire, after all.
  • Unlimited Wardrobe: How many outfits has she worn now? Notably, since she had a different outfit for each of her appearances, she was the first character to avert Limited Wardrobe. Considering that she's over a thousand years old, it's probably not that weird to see her having many clothes.
  • Unscrupulous Hero: She sometimes saves the day only because she wants to, and screwing with an evil person like herself is more fun than screwing mortals over.
  • Vampire Hunter: She used to hunt vampires to keep her human friend (later friends) safe. She personally would have wiped them out if not for the last one turning her as he died.
  • Vampire Monarch: Specifically, she's the Vampire Queen. There aren't any other vampires left to rule over, but her presence at the meeting of Ooo royalty suggests that her position is at least somewhat meaningful.
  • Vegetarian Vampire: She'll drink blood if she's desperate, but she mostly just drains the color from red objects. Sometimes the objects are fine afterwards, sometimes they seem shriveled up.
  • Visual Pun: Her bass is an axe.
  • Voluntary Shapeshifting: Has a habit of going from her cute normal form to very grotesque monster forms and back again at the drop of a hat. Her second episode really plays this up.
  • Weakened by the Light: Though, oddly, only by direct sunlight. She'd be just fine on a sunny day with as little as a large hat or parasol, though she does mention that it is painful in a very minor way. It appears to burn quite severely - barely a second's exposure results in a bunch of painful-looking boils (that she can heal away, but still).
  • "Well Done, Daughter!" Girl: She wishes for the approval and attention of her neglectful father, as she isn't secure if he even loves her. He does, but is not good at showing it.
  • Who Wants to Live Forever?: She implies this in her Journal Song:
    Marceline: (singing) They don't know what it's like to live forever and forget who they even are...
  • Wound That Will Not Heal: She has two bite marks on her neck from the bite that turned her. They go away when her vampirism is removed.
  • You Kill It, You Bought It: She became the Vampire Queen by killing the Vampire King.
  • Your Soul Is Mine: She inherited the ability to suck out a person's soul from her father. Besides a longer lifespan, she's said it's the only special ability she has from being half-demon.

    Ice King 
http://static.tvtropes.org/pmwiki/pub/images/Ice_King_6609.png
"I only try to kill you 'cause you're PRINCESS-BLOCKING ME ALL THE TIME."
Voiced by: John Kassir (2006 pilot), Tom Kenny (the series)

An unruly monarch from the Ice Kingdom. Once a close friend or even a father-figure 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 driven insane 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.
  • Abhorrent Admirer: To the extreme, in both the romantic and platonic senses.
  • Adipose Rex: Subverted. While he looks extremely stout, it's actually just an optical illusion caused by his beard and abnormally puffy robe. He's actually extremely skinny, bordering on emaciation. Season 4 and 5, however, have shown that he's gained some weight.
  • Adorkable: When he's not being creepy, the Ice King kind of has a bumbling sweetness about him. Its a hold over from his Simon-personality, who is dripping with this.
  • Adult Fear: Going insane and feeling your mind slip away, in addition to driving away your loved ones.
    • Simon was also afraid of leaving little Marcy all alone again if and when he completely lost his mind.
    • Having a small child in your care coughing and feverish in dangerous conditions with no available medicine or nutrients.
  • Ambiguous Disorder: His forgetfulness, carelessness and ditzy behavior and what the crown did to him are reminiscent of someone with dementia. This is more obvious with his interactions with Marceline.
  • Ambiguously Brown: Before being cursed with the Crown.
  • Amulet of Concentrated Awesome: If he loses his crown, he loses all his powers. Seems he needed to keep it on his person (if not actually wear it) as Simon, in order to stay alive.
  • And I Must Scream: Somewhere deep within the ball of insanity that is Ice King, Simon's aware of what he is... or at least, when he went back to normal, he was aware. And terrified of becoming Ice King again.
  • And Now You Must Marry Me: His entire purpose in life. He just wants to be Happily Married! Obviously kidnapping princesses and marrying them by force is the only way to make that beautiful dream happen!
  • And Show It to You: It turns out that Ricardio is the result of Ice King accidentally doing this to himself as the result of a botched spell.
  • Anti-Villain: Somewhere between Type II and Type IV. He usually has no idea what he's doing is wrong, but is just too crazy to notice due to his crown.
  • Apocalyptic Log: A series of video tapes show him going from a normal man named Simon, to the Ice King he is now.
  • Apologetic Attacker: Somewhat. In the episode "I Remember You", his notes (which he mistakes for lyrics) are, to put simply, him apologizing in advance for what he does.
  • Arch-Enemy: Zigzagged with Finn: while he's certainly Finn's most frequently-encountered foe by far, there's very little hate or fear between them: Finn considers the Ice King little more than a nuisance, and Ice King actually considers Finn a friend.
  • Artifact of Doom: His crown is revealed to be the cause of his insanity and why he's the way he is. Also appears to have its own will, which it tries to impose on its wearer.
  • Ax-Crazy: He's mentally unstable and likes kidnapping people. However, he appears to draw the line at using lethal force on sentient beings, even though it's repeatedly shown that he's more than capable of it.
  • Backstory Horror: A surprisingly sinister revelation in the last few minutes of the lighthearted "Holly Jolly Secrets simultaneously plays for drama the Laughably Evil and Cloudcuckoolander tropes he so happily personified. The transformation of a perfectly normal human-being into a deranged cartoon character was chilling, to say the least. Later episodes show that the process was slow and painful, driving away his fiancee Betty and a young Marceline through sheer insanity.
  • Badass Bookworm: His former self Simon Petrikov seems to have been this.
    • Simon was definitely this. In Betty, within minutes of awakening he knocks out Ash in one punch because he needs to use his flying carpet. He also manages to whip up a machine that opens a time portal in the time it takes Marceline, Finn, and Jake to get to the Ice Kingdom. (Although it's possible he was working on it during his previous periods of sanity.
  • Bandage Babe: "What is Life?" demonstrates that his underwear is just some gauze.
  • Barefoot Loon: He's always barefoot and is quite possibly the craziest character in the show.
  • Beat Still, My Heart: Ricardio's existence.
  • Big Bad: In season 1, he can be considered one of the main antagonists of the show, constantly stealing princesses so he can marry them. After that he generally becomes a Harmless Villain, with The Lich taking over as the show's Big Bad. However, he worsens sometimes.
  • Blank White Eyes: A side effect of the crown, they're his Wizard Eyes, allowing him to see the strange beings of the Spirit Realm, which probably took a toll on his sanity.
  • Blessed with Suck: As we learn in "Holly Jolly Secrets", his ice powers helped him survive the nuclear winter, but at the cost of his sanity and humanity, and he outlived the only woman he ever loved. Or so he thought...
    • He also sees crazy things later revealed to be the very real and very creepy denizens of the spirit realm with his "Wizard Eyes" all the time.
  • Blow You Away: He commands arctic winds to chill and freeze things and it seems to accompany his flying.
  • Body Horror:
    • He temporarily removed his own heart. And gave it life as Ricardio. On another note, during the process that turned him into the Ice King, his skin turned pale blue and appeared frostbitten when his body temperature had dropped to only 80 degrees (F). Presumably he got even colder, as he's fine going barefoot in the snow.
    • Taken Up to 11 in "Lady and Peebles" when Ricardio makes a body for himself using tissue and broken bones he pilfered from the Ice King. While still inside the Ice King's body.
  • Butt-Monkey: Ice King is very unlucky, constantly either getting hurt or having something bad happen to him.
  • By the Eyes of the Blind: The crown gave him the ability to hear and see spirits.
  • Cerebus Retcon: Everything about him in "Holly Jolly Secrets."
  • Characterization Marches On: Was a more traditional villain in the original short, being much more of a threat (actually physically engaging Finn/Pen, for one) and playing typical villain tropes like Evil Laugh and Sesquipedalian Loquaciousness straight. There was scarcely a hint of the harmless Cloud Cuckoolander he would become in the series.
    • He's also unusually nasty by later standards in "When Wedding Bells Thaw", in which he comes close to mind-controlling Old Lady Princess into marrying him.
    • And then we found out about his past, making him a Tragic Villain...
  • Classical Anti Hero: A Chaotic Stupid example.
  • Cloud Cuckoolander: Ice King has odd plans, odd mannerisums and generally doesn't make sense. This is because the Ice Crown drove him nuts. It's Played for Drama during a flashback episode that shows Simon Petrikov was terrified of losing his mind. The Ice King is less than a shadow of the dignified antiquarian he once was, no longer caring that he's gone insane. "I Remember You" suggests that he's not even aware that he's even gone insane, even with the truth from his own words being sung right in front of him. However it's kind of implied that Simon was already a bit of a Cloudcuckoolander, he just wasn't insane. For example, he compares being the Ice King to "living with eternal diaper butt".
  • Continuity Nod: After his back story is revealed several characters refer to the Ice King by his real first name.
    • In "Beyond This Earthly Realm.
    Finn: Ice King? Ice King! Where'd you go, Simon?
  • Cool Old Guy: Sort of. He has a wacky sense of humor, plays on a drum kit and has a bunch of ninja stuff.
  • The Corruption: In "Simon And Marcy", it's shown that Simon is able to resist the crown's influence when he's not actually wearing it, but dangerous circumstances forced him to use its power more often than not. Eventually he becomes the Ice King permanently.
  • Dark and Troubled Past: For so lighthearted a character, he has had one of the darkest and most painful pasts of any character on the show, stretching back an entire millennium to when he was a perfectly normal, happy young man. He survived the Mushroom War and a post-apocalyptic ruin of world, and became a temporary guardian to a young girl, but lost it all along the way to insanity and senility.
  • A Day in the Limelight: "Hitman" gives him the most amount of focus compared to any other episode. "Holly Jolly Secrets" involves his Origin Story, among other things.
  • Death Seeker: When he is temporarily reverted to Simon Petrikov, he would rather die than go back to being the Ice King. Betty talks him out of it, saying that she will find him a cure.
  • Desperately Craves Affection: His surface-level motivation for wanting to kidnap a Princess - he just wants to be loved. The heart of the matter, though, is considerably more complex and spoiler-laden.
  • Determinator: Ice King doesn't give up easily on much. He carried it over from his former self Simon Petrikov, who fought long and hard to try and keep his sanity, and while we know he eventually loses the battle, seeing him trying, and succeeding, at holding onto his mind while using the power of the crown while singing the saddest rendition of the theme song to Cheers ever is amazing.
  • Dirty Old Man: Justified, sort of; he goes after young princesses because his lost love Betty was young when he last saw her, and his own immortality and insanity began when he was young (albeit artificially aged). Unjustified with him wanting to date Fionna. Granted, he doesn't seem to think he's old.
  • Distaff Counterpart: Ice Queen, who he himself created for his gender-swapped fanfiction.
  • Does Not Like Shoes: Even if he's standing in snow, he won't be wearing any sort of footwear.
  • Does This Remind You of Anything?:
    • The ice crown's corruption of his mind has often been compared to alcoholism, Alzheimer's disease and/or dementia.
    • And his "Wizard Eyes" are not unreminiscent of schizophrenia.
  • Dying as Yourself: His goal when the Ice Crown's magic is temporarily removed, reverting him to Simon Petrikov and revoking his immortality. Unfortunately for him, Betty won't let it happen.
  • Elderly Immortal: He is immortal in terms of aging, though whether he can be killed is still unclear.
    • When he's briefly reverted back to Simon in "Betty", Death shows up to taunt him that he'll be the Ice King "'Til the sun blows up". So it seems likely that he is immortal for any reasonable definition of the term.
    • His elderly appearance is also a side effect of the crown, as the crown slowly turns its wearer into Evergreen clones; If he completes his transformation at the same time Marceline is turned into a vampire, Simon's biological age would have stayed at 57.
  • Elemental Powers: His crown provides him with amazing control over ice and snow, possibly augmented by Ice Ninja prowess.
  • Enemy Mine: Teams up with Finn to defeat the Lich.
    • This may have been his motivation in "The Cooler", given how badly the Ice Kingdom was affected by just Flame Princess.
  • Enemy Summoner: As seen in "Prisoners of Love".
  • Even Evil Has Standards: Decides to stop pursuing Princess Bubblegum after it's pointed out that he's old and she's been turned into a thirteen year old. In "Hitman", he also draws the line when Scorcher tries to kill Finn and Jake instead of literally hitting them.
  • Evil Is Deathly Cold: While not really evil, he is the Ice King.
  • Evil Old Folks: Played with. More insane than anything.
  • Evil Overlord: Has the spiky crown, Faceless Goons (Penguins, Yeti and Type I Snowlems), magic, etc. Every typical aspect of the trope is present, so it is of course totally subverted. He isn't really "evil" for one, and it's often more like he just has the biggest house in the Ice Kingdom.
  • Evil Plan: Kidnapping princesses because the ice crown drove him insane.
  • Expy: From Dr. Two-Brains.
  • Fallen Hero: Though not completely fallen, since some part of mind is still fighting the Crown (it's just buried so deep that not even he is aware of it).
  • Flight: Via his beard.
  • The Fog of Ages: He's been alive since before the Mushroom War, but has only the vaguest memory of times before the series. He can't even remember his own name, let alone his former life.
  • Freudian Excuse: His desire to kidnap princesses is revealed to be a degenerated desire to see his fiance Betty again. Whom he referred to as "his princess".
  • Friendly Enemy: From Season 3 onwards. Noted to not usually be a "serious threat" in Season 4, so maybe he's improving a little?
    • From Earth & Water to the end of Play Date he lived with Finn and Jake while his kingdom was rebuilt.
  • The Friend Nobody Likes: Seems to be becoming this in Season 5. The others invite him to things and put up with his annoying behavior out of pity. Marceline seems to be the only one who genuinely likes him, and even then it takes her a while to want him around her again, as up until "I Remember You" it was difficult for her to even be in the same room with the guy. It seems that doing so brought back...unpleasant memories for her.
  • From Nobody to Nightmare: Was just a normal human with aspirations to become a certified and respected antiquarian, until he found the crown.
  • Future Loser: Mushroom War era Simon was a certified Badass. Ice King, not so much.
  • Gag Nose: Somewhat odd, given he didn't have one as a human.
  • Hair Wings: He can fly using his beard.
  • Harmless Freezing: Applies anytime he freezes something living, which is a little weird given his insanity.
    • It's established that, when he was still oscillating between Simon and the Ice King, he wasn't always so lenient - we see him unnecessarily freeze a deer to death by asphyxiation. He's noticeably holding back in the present day, though whether he does so consciously or not is debatable.
  • Hearing Voices: The insane variation; caused by his crown. That's not figurative, by the way - the crown is established as actually talking/whispering to its user. He doesn't mention them at all in the present day, so he may be tuning them out. Or they don't bother talking to him anymore because he's already a crazy ice wizard. Or he still hears them, but no longer makes any distinction between the voices and his own thoughts, so he doesn't see any point in mentioning them.
  • Heel–Face Turn: Season 3 onwards. He sometimes causes problems, but almost never has any malice to it. And then Princess Bubblegum somehow talked him into attacking the Fire Kingdom directly in a coordinated distraction...
  • Her Code Name Was "Mary Sue": Writes himself as one in the "Fionna and Cake" universe. He saves Fionna and Cake from Dr. Prince just by reasoning with him, and the duo automatically adore him and become best friends with him for no good reason.
  • Hero of Another Story: As Simon Petrikov during the aftermath of the Mushroom War where he was Marceline's Parental Substitute.
  • Heroic Sacrifice: Farmworld Ice King was able to stop the bomb that would create the Lich, but in doing so was crushed underneath the frozen bomb.
    • Played for Laughs in "The Wand", where Finn and Jack direct him to sacrifice himself to stop the wand and he happily does so.
  • Heroic Willpower: The season 5 premiere implies that a normal person would fall into complete insanity in a few hours while wearing the crown, and freeze the world. Not only was Simon able to retain his sanity for long periods of time inbetween bouts of insanity, even 1000 years later as the insane Ice King he still has not fallen to the crown's influence enough as to try to do it. He may be repressing the worst of the crown, or it may even have given up.
  • Hidden Depths: Has more than the rest of the cast combined, thanks to his age and hobbies.
    • Turns out, he can survive on a desert island (actually Island Lady) without using his crown at all. (It's not too surprising when you know his history, but that he can call it up at all comes out of left field...)
  • An Ice Person: As may be obvious. Knowing "The secrets of ice and snow", he is powerful enough to freeze the entire world, but has refrained from doing so so far.
  • I Just Want to Be Loved: He said so himself in "I Remember You", and strongly implied in his actions elsewhere.
  • I Was Quite The Looker: Simon was relatively handsome; at least enough to be depicted with the same Generic Cuteness as most other characters (as opposed to Ice King's Gonk big nose and aged appearance).
    • The Ice King himself however doesn't seem to think so- he's too embarrassed to let others find out that he used to wear glasses.
    • The glasses get mentioned again, The Empress (a vampire whom he has an unelaborated history with) tells Marceline:
      Empress: He used to have more of a Silver Fox thing going on, with his hair and his cute glasses."
  • Ignored Epiphany: When he gets knocked out while fighting Finn, the Cosmic Owl appears and attempts to tell him he's insane. His response is to call the Cosmic Owl a big nerd, after which he is tickled into consciousness by penguins.
  • Immortality Begins at 20: A variation; the crown artificially aged Simon rapidly, but thereafter he doesn't seem to have changed much over the course of the hundreds of years he's been alive.
  • Immortality Inducer: The crown has kept him alive for a very long time. Unfortunately, it's also driven him insane and No Immortal Inertia is in effect.
  • Ineffectual Sympathetic Villain: He generally comes across this way, to the point that it is often hard to consider him a real villain, or even an Anti-Villain. The impression is helped by an apparent unwillingness to take the gloves off unless his life is on the line (something only forced by the Party God and Flame Princess, to date), and even then he holds back some.
  • The Insomniac: Implied in "The Eyes".
  • Jerk with a Heart of Gold: A sympathetic example after he Took a Level in Kindness. He is actually a nice guy, but he does have the tendency to get into rather violent fights with a 14 year old boy and a dog, and he regularly kidnaps and harasses princesses, blatantly ignoring their distaste and cries for help.
  • Large Ham: Simon can be see hamming it up a little to keep Marceline's spirits up as well.
  • Lean and Mean: Subverted. While his large robe gives him the appearance of a large man, he is actually exceptionally skinny (to the point of emaciation) most of the time. However, Ice King is more of an Ineffectual Sympathetic Villain than evil.
  • Limited Wardrobe
  • Literal-Minded: Hires a hitman against Finn and Jake, thinking he is literally going to hit them, not kill them!
  • Logical Weakness: He can't use his powers properly in high temperatures.
  • Loss of Identity: Due to his insanity, he can't even remember who he once was. He's aware that he has a "tragic backstory", but in "I Remember You" he never seems to make the connection that the "lyrics" he wrote are really just his journal, and in "Simon and Marcy" he apparently never realizes that "Simon" in the story Marceline is telling is him (or, for that matter, that "Marcy" is her).
  • Love Hungry: In "I Remember You," he quite literally yells "love me! Love me! Love me!"
  • Magical Barefooter: He is an ice wizard and he never wears any footwear.
  • Meaningful Name: His heart's name is Ricardio.
    • His true name is Simon Petrikov. Simon being derived from the Hebrew name "Shimon", which means "He who listens". "Petri" means frozen.
  • The Men First: When Flame Princess destroys the Ice Kingdom, the Ice King pleads Finn to save Gunther. Subverted immediately afterward ... as Finn runs off to do so, Ice King can be heard in the background clarifying: "... I meant, after you save me."
  • Neutral Evil: In-universe-assigned alignment in the comic series. He's really either True if not Chaotic Neutral.
  • Ninja: He has a collection of ice kunai, shurikens, and a book on ice-themed ninjutsu.
  • No Immortal Inertia: As revealed in "Betty". When the Ice Crown is depowered, Simon is revealed to be dying because, as he puts it, "I'm old."
  • No Social Skills: He does have them, if you want to be precise, but even on a good day he misuses them.
  • Not Evil, Just Misunderstood: Or mental, to be precise.
  • Nothing but Skin and Bones: The Ice King is actually very skinny under his robe, though he sometimes works out and consequently buffs up a little..
  • Not-So-Harmless Villain: There's a trend of following every episode where he's deeply tragic with an episode that reminds the audience that he's dangerous. After "Holly Jolly Secrets" comes "Princess Monster Wife", where he mutilates the princesses to create his own, and after "Simon and Marcy" comes "A Glitch Is A Glitch", where he creates a computer virus to delete everybody except him and Princess Bubblegum.
  • Papa Wolf: It's not a good idea to endanger little Marceline when she's with Simon.
  • Parental Substitute: Simon was this to Marceline, in the aftermath of the Mushroom War.
  • Person of Mass Destruction: On the tapes chronicling Simon's descent into Ice Wizardry, it is shown that the initial transformation was accompanied by the rapid formation of an extremely violent blizzard. It's also possible that this is instead the result of a nuclear winter, presumably from the "Mushroom War," though that would be quite a coincidence.
    • Muddying the waters even further, the alternate universe shows that the crown can, without a live host, freeze the entire world for 400 years. The aforementioned blizzard was likely a subconscious reflection of that. However, Ice King himself never consciously uses his powers this way.
    • While the Ice Kingdom currently covers only a small part of Ooo centered on his cave, there are fjords and what appear to be moraine islands around the entire island.
    • His dandruff is toxic enough to cause a nigh-lethal pandemic.
    • He is capable of depowering the Fire Kingdom's heat source if necessary.
  • Power Born of Madness: The crown granted him ice powers at the cost of his sanity.
  • Pre-Insanity Reveal: The Ice King was a historian named Simon Petrikov until he put on the Ice Crown, which gave him ice powers and immortality but made him slowly lose his mind. This has been a real Tear Jerker throughout the series.
  • Prehensile Hair: A secondary power granted by the crown. He can fly with his beard, and he's got no way of flying without it.
  • Really 700 Years Old: He was a part of pre-fall mankind so this makes him the oldest member of the regular cast. In "Simon and Marcy", set 996 years earlier, he mentions he is 47, making him 1043.
  • Redemption Promotion: While he hasn't completely pulled a Heel–Face Turn yet, he is far more effective when helping Finn and Jake than fighting them. He even froze the Lich solid after everything else had failed to beat him.
  • Rule 63: In-universe, he's the creator of the Fionna and Cake world. He initially refers to it as fan fiction, but later on appears to believe - or be trying to, anyway - that they exist somewhere.
  • Sanity Slippage: The crown causes this to happen to him, progressively warping him into the Ice King.
    • Being harassed 24/7 by the spirits in his castle (that only he can see, thanks to his wizard eyes) probably hasn't helped any, either.
  • Saying Sound Effects Out Loud: Likes to vocalize the "Zap!" sound his ice powers make.
  • Sesquipedalian Loquaciousness: Displays this trait a few times in the original short ("FOUL AND NOISOME WHELP!"). Unfortunately, it's all but gone by the start of the actual series.
  • "Shaggy Dog" Story: His backstory's littered with them. In "Simon and Marcy", it was shown that at some point he began to have control over the crown and keep a hold on his sense of self, and the flashback ends on a hopeful note. This turned out to not be the case. In addition to that, the flashback shows him trying to save Marceline from her fever, but ends with the miracle cure of him feeding her chicken soup, being deluded enough to think that's all he needed to do (and providing the first hint of his intense psychoses) - though, between Marceline's biology and the fact that she was telling this story, the truth isn't totally clear.
  • Shock and Awe: Uses blue lightning a lot ("Zap"), though it usually just freezes stuff.
  • Shout-Out: Apparently Simon was a fan of Cheers.
  • Silver Fox: Thinks he's this, though at most he's Ugly Cute. He seemed to count mid-corruption though, if the Empress is any indication
  • The So-Called Coward: While he's been shown to be easily horrified by Eldritch Abominations, and Word of God stated that he'd run from The Lich, he actually assisted Finn against him willingly to save Princess Bubblegum.
  • The Southpaw: "Mystery Dungeon" reveals him to be a left-handed writer.
  • Squishy Wizard: Gets easily smacked down by Finn every time the two come into direct physical contact.
  • Survival Mantra: When Simon put on the crown to protect Marceline, he used the theme from Cheers to keep himself sane. Though eventually, he eventually loses what's left of his sanity.
    • Also, a particularly tragic example as, they could've used any sitcom theme song, but the theme to Cheers specifically is about wanting to go to a place where you have friends who understand your problems, on top of the well-known, "where everybody knows your name" line. Poor Guy.
  • Sympathy for the Devil: The Ooo version of Christmas was created by Finn and Jake solely due to this trope.
  • Token Evil Teammate: Starting with Season 3, when he becomes more sympathetic and other, more villainous villains start showing up.
  • 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.
  • Trauma Conga Line: His backstory before becoming the Ice King is one long list of tragedies. He ends up going berserk from putting on a crown he didn't know was cursed, drove the women he loved away(she actually went to the future), had to raise a little girl in fear of losing his mind before giving her away to protect her all while the end of the world is happening around him. It's a wonder he was able to stay sane as long as he did, much less against a crown making him crazy.
  • Unskilled, but Strong: His insanity makes him dumber than a post and unable to defend himself against true threats, but as "Frost and Fire" proved, he is way more powerful than he seems.
  • 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, which forces Bubblegum to return to her 18-year old form and blow off Finn, eventually leading to Finn meeting Flame Princess. Whew. At least the Lemongrab part 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.
    • He is also responsible for Finn losing his demon sword.
  • Villainous Rescue: Assists Finn and Jake against The Lich to save Princess Bubblegum.
  • Villainous Friendship: Gunter the penguin is probably his best friend.
  • Walking Spoiler: It's hard to talk about the Ice King without spoiling his backstory or important aspects of the story's backstory, especially in later seasons where it's brought up more often.
  • 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.
  • Weak, but Skilled: As Simon, he may not have access to all of the powers the Crown gives him, but he is much more competent than his icy counterpart.
  • 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.
  • White Hair, Black Heart: ...well, he's got the white hair, anyway. His heart is also Ricardio, so there's that too, but the Ice King himself comes off as more neutral than evil.
  • Willfully Weak: The Ice Crown gives him enough power to freeze an entire planet for centuries and create entire armies of snow-creatures, but he almost never uses anything close to his full potential. Presumably, whatever remains of Simon keeps his deranged self from tapping into his full powers - we see him cut loose twice in the present day, and both times his life was on the line.
  • 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 Marceline out of the knowledge that she's important to him, even if he can't remember why.
    • Simon reveals this may work both ways. When his sanity was restored in "Betty" he describes his memories of the ice king as dream-like impressions.
  • 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 male example.
  • Younger Than They Look: Initially the crown aged him faster among other things, looking like an old man despite being in his forties. Though once it was complete he stopped aging and is MUCH older than he looks.

    Flame Princess 
http://static.tvtropes.org/pmwiki/pub/images/tvtropes_flame_princess_4266.png
"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

  • Action Girl: She's incredibly powerful and destructive.
  • 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 tends to handle situations like a '90s 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).
  • Amicable Exes: With Finn as of "Bun Bun".
  • 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 Adorable: Admit it, you'd totally hug her if she wouldn't accidentally burn you to a crisp.
  • 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.
  • Broken Bird: She's been lied to and used for the sake of keeping power, her buttons have been further pushed when Finn unintentionally made her destroy the Ice Kingdom. Her tragic childhood led her to develop violent behavior that has decreased when dating Finn.
  • 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.
  • Calling Your Attacks: Does this a few times in "Vault of Bones"
    Flame Princess: SCATTER FIRE! SNAKE FIRE!
    • In "Frost and Fire"
    Flame Princess: Infernoooooo Blast!!!
  • 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.
  • 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. (Unusually for the show, she's shown to learn something and grow with each appearance.)
  • 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.
  • Cute Monster Girl: She's much more humanoid than most Flame People, who more often look like flames in half-melted rock "clothing" with minimalist human facial features.
  • Daddy Issues: She's got some animosity with her father thanks to him sealing her in a lantern for most of her life.
  • Dark and Troubled Past: Poor girl was sent to the woods as a child just so her father could have power. Then was trapped in a lantern for 14 years because of her Jerkass father's carelessness. What the poor girl went through was one of the reasons why she was so violent in the past.
  • Demoted to Extra: At one point, she was considered among the main cast. She was demoted to secondary status after "The Red Throne"... though in-universe this is because she doesn't leave the Fire Kingdom much, so any episode featuring her ("The Cooler", for example) basically has to take place there.
  • Does Not Like Shoes: Flip-flops on this one. Her first dress didn't come with shoes, but she wears slippers (flats?) with her second dress - maybe she has a better grasp of outside culture by that point? Her third dress in Vault of Bones has her back to being a barefooter, and by the time she's the new ruler of the Flame Kingdom she wears boots as part of her outfit.
  • 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.
    • She is apparently the Fire Elemental of Ooo, which would explain why she is so powerful.
  • 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.
  • Fatal Flaw: She has two, her inexperience and her temper. Princess Bubblegum exploits these and plays her like a fiddle in "The Cooler".
  • 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.
    • However, she goes into a blind rage and destroys 5 of 6 priceless artifacts in "The Cooler". Granted, this was probably a good thing overall, as while she is unlikely to have ever used them, her brother was clearly looking for an excuse to.
  • 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. It's less "hair trigger" with each appearance, though she still has a temper.
    • Comes to a head in "The Cooler", where it plays out as her Fatal Flaw. Whether it was on purpose or not, Princess Bubblegum was able to trick her into destroying 5 of 6 ancient weapons in a blind rage and came just short of killing Bubblegum.
  • 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.
    • "The Cooler" points out that her area effect fire attacks are a liability even in the Fire Kingdom.
  • 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, er, 'King'.
  • Knight of Cerebus: Of a much more nonstandard variety than the Lich. She doesn't appear very often, but when she does her episode will inevitably result in major shifts in the plot accompanied by Finn learning harsh life lessons. She's not a deadly serious villain, but she's a character whose presence always makes the show dive into more complex relationship plot lines than usual.
  • 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.
    • Her first name, Phoebe, means "bright and shining" or "bright and pure", which fits her direct personality well.
  • 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: Without a nose she can still smell.
  • Not Good with Rejection: To say that she doesn't take rejection well would be putting it lightly. (Though, with Character Development working for her more than any other character in the show, there's a world of difference between her earliest and later reactions to it.)
  • 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.
  • Politically Active Princess: Unlike the Candy Kingdom, the Fire Kingdom has war hawks and the occasional backstabbings, so she has had to adapt very quickly and ultimately leans towards a more democratic society than you'd expect from a royal family. While clearly not the genius that Princess Bubblegum is, she genuinely wants peace, and can be seen attending the conference in "Princess Day".
  • 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.
    • Later episodes make it clearer that she's gotten much better at controlling her own fire most of the time. She is also poisoned in "The Red Throne", which seems to have capped her power for some time afterwards.
  • 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.
  • Pretty Princess Powerhouse: Don't let the princess outfit and general friendliness fool, it is very likely that she is the most powerful princess in Ooo. 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.
  • 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 Naďve: 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.
  • 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.
  • Surrounded by Idiots: She has actual advisers - mostly family - but they aren't much help.
  • That Makes Me Feel Angry: Initially has some trouble describing herself (she's 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.
  • Tsundere: She makes Asuka Langely Soryu look tame by comparison! 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.
    Jake (pretending to be Finn): (after learning she's evil and psycho) Y'know, On Second Thought, we're not really each other's types...
    Flame Princess: ...We're... what?
    Jake (pretending to be Finn): I changed my mind. I don't like you.
    Flame Princess: You... WHAT?!?!?!
  • 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.
