The Ice King's favorite penguin and servant. May be the ultimate evil power in Ooo, if Marceline's dad is correct. It has been suggested that the Ice King just calls whatever penguin is closest Gunter. [[spoiler:The one pronounced Gune-ter is actually an EldritchAbomination/space god named Orgalorg that was seeking to absorb the power of the comet but got banished to Earth and transformed into a "cuddlier, less threatening form" due to the gravity of Earth.]]

* ArcherArchetype: She can shoot arrows without a bow, likely due to magic.

* CrazyPrepared: He somehow knew [[spoiler:he would be reverted to child form, and performed a ritual to bind his soul to his future self in the event of that becoming a reality.]]

* SpellMyNameWithAnS: Sometimes Ice King says Gunther instead of Gunter. This fits with Ice King's scatterbrained nature.

* SpellMyNameWithAnS: 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".

---'''Simon:''' Where are you going!?

--'''Simon:''' Where are you going!?

* OfficialCouple: With Simon... kind of. It's complicated.

* StarCrossedLovers: Implied in "Holly Jolly Secrets", with Simon having come to believe that she met her end in the Great Mushroom War. In "Betty", it turns out she didn't die after all... and she makes it her goal to save Simon from his fate.

* YourDaysAreNumbered: [[spoiler:After he kills the grass demon, his body starts to deteriorate. Justified since the grass demon was a part of him since his existence. He finally falls apart and reverts to a Finn Sword-shaped seed after Golbetty leaves Ooo.]]

* LoveMartyr: Deconstructed; as her character is developed it's established that she spent so much time supporting Simon that she's barely considered what she wants for herself. ''Fionna and Cake'' expands on this by showing she put her life and career on hold to be with Simon and support his studies. The two of them realize that this relationship was an unwittingly toxic AllTakeAndNoGive and that she shouldn't have sacrificed so much and Simon should have been more thoughtful towards. Then it is reconstructed in a bittersweet way since she says she does not regret her choices, but is also willing to move on now that she's given all she could and a relationship between them is no longer possible.

A very loud lemon drop man created in a lab by Princess Bubblegum in case she was ever unable to rule the kingdom. The first one of the princess's experiments gone wrong, he has a... "special" way of thinking and looking at the world. He lives with a clone of himself (so aptly named Lemongrab 2) and their Lemon Children/Subjects in Castle Lemongrab. He eventually became a power-hungry tyrant who ate his brother, but thanks to Lemonhope, he was defeated and PB combined the two Lemongrabs into Lemongrab 3, who has mellowed out. As Lemongrab 3, he becomes much more empathetic and retains at least some of his earlier incarnations memories, if not all of them.

* MidSeasonUpgrade: 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. [[spoiler: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.]]

* OnlyMostlyDead: 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. [[spoiler:In the season finale, it grows back again, fusing with his regrown arm]].

* WalkingSpoiler: [[spoiler:Its very existence on Finn's arm already concludes the (possible) final fate of Finn's missing limb conundrum.]]
** [[spoiler:This also applies to Fern's entire existence.]]
*** [[spoiler:Not to mention Fern's transformation into the Green Knight.]]

* CallingYourAttacks: Does this a few times in "Vault of Bones"

** In "Frost and Fire"

* ElementalEmbodiment: 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.
** [[spoiler:She is apparently ''the'' Fire Elemental of Ooo, which would explain why she is so powerful.]]

* GodSaveUsFromTheQueen: 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.

* MeaningfulName: Other than the obvious, she's [[StealthPun Finn's new flame.]]
** Her first name, Phoebe, means "bright and shining" or "bright and pure", which fits her direct personality well.

* PowerIncontinence: 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.

* ZeroPercentApprovalRating: As established in "You Made Me!", just about ''everyone'' in the Candy Kingdom completely despises him and vehemently protest against Princess Bubblegum's request that some of them go to Castle Lemongrab to keep him company. One Candy Person, Mr. Cupcake, actually goes so far as to ''break his own arm'' to have an excuse not to hang out with Lemongrab.
** Averted as [[TheGoodKing Lemongrab 3]], at least in his kingdom.

** '''[[InsistentTerminology IT'S A SOUND SWORD!!]]'''

** EvilWearsBlack: Starting to lean towards it in 'Too Old' with Lemongrabs 1 becoming more abusive and Lemongrabs 2 trying to give at-least some hope to the Lemon Children in some doses. Played completely straight in "Lemonhope".

* EvenBadMenLoveTheirMamas: It's a complicated, dysfunctional relationship, but the Lemongrabs both hold Princess Bubblegum in high regard, feel comfortable with asking her for help, value her opinions, and think of her as a mother even though she has never referred to them as her sons.

* EvenEvilHasLovedOnes: While definitely not [[NotEvilJustMisunderstood evil]], the Lemongrabs certainly are petty, spiteful assholes, and very vindictive people. But they are openly doting to their children, loving to one another, and seem to care about their mother, though their relationship with her is complicated. This ends up all undone for Lemongrab 1, at least in regard to his fellow lemon folk, but amplified for Lemongrab 2.
** Averted as Lemongrab 3. In contrast to his former personality, he becomes a good king.

* FreudianExcuse: The reason he's a miserable, sour and paranoid jerk is because he's lonely, being the ''only'' one of his sour, lemony kind, mostly because he was a failed experiment. That is, until Lemongrab's clone shows up. After that, he's a bit less of a jerk, and noticeably happier. Sadly, it doesn't [[TookALevelInJerkass last]]. Fortunately, he got a happy ending as Lemongrab 3.
** This might also explain why Lemongrab 1 goes crazy while Lemongrab 2 does not. 1 suffered all the effects of loneliness, while 2 has never known a life without his beloved brother.

* IJustWantToBeNormal: Related to the trope below, though it's an interesting example. He does try to be normal and do the right thing, but he just can't seem to manage it, and his failures cause him to become frustrated and lash out at others. He also becomes increasingly bitter that he's the one expected to change when no one is willing to put up with him the way he is, despite his "defects" being beyond his control.

* IJustWantToHaveFriends: Implied to be Lemongrab's reason for even coming back to the Candy Kingdom. It was thanks to Bubblegum creating a second Lemongrab, exactly the same in every way, to ease up on their sour attitudes. Both of the Lemongrabs then use the Princess's formula to endlessly create life, thankfully they had the formula removed.

* ItsAllAboutMe: Demonstrates many traits of this trope, particularly in "Too Old".
** Averted as Lemongrab 3. As a good king, he really seems to care about his children.

* JerkWithAHeartOfGold: Zig-zagged. Lemongrab's a big jerk, there's no denying that. But he's a big jerk who also happens to care immensely for his best friend, and he loves his children, enough to starve himself just to welcome more children into his family. It's taken a while, but his lemon heart has sweetened up just a little bit. Until he got even worse than before in "Too Old".

* MadeOfIron: His skin is so thick that it's literally impossible for him to explode, according to the creators. He also fell head-first out of the top-story window of a castle, and landed on his head with such force that he had to physically strain to pry himself out of the earth... and he was completely unharmed.

** Brought up again in "Too Old."
* NeverMyFault: Both Lemongrabs are incapable of taking responsibility for their actions. They'll blame whoever is nearby when they do something wrong.
** Subverted in "Too Old" for Lemongrab 2, who states that he has "learned his lesson," showing that he at last knows his behavior in the past has been wrong and that lemon people don't need to act like that.

* NotEvilJustMisunderstood: The creators of the show repeatedly have to assure fans that Lemongrab is not evil. (At least, not intentionally so.) Even his full-on cross to the dark side has more to do with his mind deteriorating completely than with any actual malice.

* SanitySlippage: He isn't exactly inherently "sane", but he gets even more unhinged in Season 5 on thanks to his mommy issues.
** Averted as Lemongrab 3. Although he is still as weird as ever, he is not dangerous.

* SophisticatedAsHell: He has exceedingly pedantic speech, and goes from speaking in a very proper and dignified way to screaming in HulkSpeak to speaking very casually with slang.
** This exchange probably sums it up best.

* UngratefulBastard: Pretty much, is a jerk to Peppermint Butler after he releases the guy from the dungeon so he can have food, electrocutes the citizens that Princess Bubblegum gave him in "You Made Me" when they end up insulting him, and demanding that Tree Trunks bake him a pie in "Mystery Dungeon" and continuously calling her "Slave" afterwards (even ''after'' he apologizes).

* WouldHurtAChild: In "You Made Me!" he electrocutes the Pup Gang because they insulted him three times and wouldn't listen to his instructions. Then, as he tried to cuddle a candy baby, he had a panic attack, and started slapping the kid around, before squealing in discomfort and shoving the kid onto the ground. He got worse in "Too Old", since he abused his own children for the slightest reasons.
** Averted as Lemongrab 3. "The Mountain" shows that he has become quite empathetic with his children.
* YouAreWhatYouHate: The people who frustrate him the most seem to be obnoxious, rude, petulant children. ''Hmmm...''

* KillerRabbit: When Marceline's dad attempts to steal his soul, he promptly slaps him.

* OneWingedAngel: He transforms into a massive octopus/jellyfish-like monster so he can envelop the comet.

* LaserGuidedKarma: The first thing Finn and Jake do after returning to Earth from Mars is knock Magic Man unconscious with a single punch.

* PsychoSidekick: He genuinely seems to have Princess Bubblegum's interests at heart, regardless of his own morality. Best shown in "The Nemesis", when he deals with one of her enemies by taking his children hostage without letting Bubblegum in on it. Some of the comics, in particular, reveal that Bubblegum knows pretty well what he's capable of and uses him to sort out problems that Finn is too nice to deal with. That being said she was not happy when she learns Peppermint Butler created a lot of weapons just to kill Marceline if she turned evil.
** Nonetheless he's absolutely thrilled to get the Vampire King's autograph.

* CharacterDevelopment: His appearance in "Red Throne" shows that he's changed from a dimwitted man-child to a competent and capable warrior.

* NumberTwo: In spite of his limitations, PB uses him for routine tasks in the Candy Kingdom.

* AnimalMotif: An elk. She rides one, wears antlers, lives in the woods, and is stoic and dignified.

* AscendedExtra: From a background character with little personality to a fully fleshed character with focus on her own episode, a recurring character during the final season and Finn's third LoveInterest.

* NotSoAboveItAll: In "Wheels" she appears in the background when Finn starts playing his flute, [[StalkerWithACrush watching him from the bushes]]. "Exceptional beasts can't fall in love," yeah, right...

* {{Determinator}}: Spent over 15 months playing a game of hide and seek which Finn and Jake ''forgot'' about.

* TheFogOfAges: Martin has memory issues, which he puts down to his incarceration in the Citadel as he had no way of keeping track of time so his recollections are skewed.
** Oh dear god, in ''Islands'' [[spoiler: it's implied that ''most'' of Martin's negative traits in the present are due to a head injury he received ''saving'' Finn. In the human colony on the islands he was always a shiftless con man, but he never actually killed anyone. We see him falling in love with Finn's mom Minerva, a doctor, and they genuinely seemed to have a loving relationship in the first months of Finn's life. He apparently fell InLoveWithTheMark, and seems to have been genuinely interested in raising Finn with her. Then he had to bail when enemies from his shifty past caught up with him, and while escaping on a raft the islands' robo-guardian attacked. He bravely left the raft to fend it off while ''explicitly'' promising Finn he'd come back for him, but the resulting explosion knocked him into the sea. 15 odd years later, Martin can't even remember any of his former life very clearly. It's Simon Petrikov/Ice King all over again.]]
* {{Foil}}: He and Finn are opposite in personality and even wardrobe. They also have differing philosophies as of the season six finale. Finn grows to believe everything has a purpose while Martin sees the universe as having no purpose (it's unknown if this leans more toward StrawNihilist or AntiNihilist, but given his cheery state and his neutral stance, most likely the latter. See HiddenDepths below for more details.) [[spoiler: Flashbacks in the Islands miniseries furthers demonstrate their differences. Finn has his moments of selfishness while ultimately remaining a good person, while Martin demonstrates moments of heroism before relapsing into his typical ItsAllAboutMe behavior, though it's heavily implied that it was due to suffering brain damage and memory loss.]]
** Also to Simon. They were both father figures (Actual father in Martin's case) to mostly human people who found their way onto OOO. While Simon was a good person who ended up being turned into a crazed husk of his former self thanks to acts of protection for Marceline, Martin [[spoiler: had some development into a good person coming for him that got interrupted and discarded all together thanks to an act of protection for Finn.]] Their significant others were also central to their development, with Simon finding Evergreen's crown and incidentally starting his path to insanity because he wanted to show it to Betty, and [[spoiler: Minerva being the first person other than himself that Martin cared about and the key to his development into a better person.]] In current times, the Ice King is a powerful but mentally unstable wizard with blue skin and a blue robe, while Martin is a normal if amoral person with a red outfit, [[BlueOniRedOni ironically being the blue oni to Ice King's red oni]]. Also, while Ice King was a recurring enemy early on in the series who developed into an ally and friend to the heroes overtime, Martin [[spoiler: did actively look out for Finn prior to his head injury]], but didn't give Finn any paternal care in the present day, outright tearing his arm off by accident and never offering Finn an apology. [[spoiler: Their fates by the show's end are also opposed, with Martin choosing to become a being higher than mortality and Simon being reverted to his primal state as a normal human being thanks to GOLB.]]
* HateSink: Those who were expecting Finn's dad to be a cool guy will be disappointed. And unlike some of the show's other most despicable people who could at least appear cool, Martin is just a fantastical version of the self-absorbed deadbeat dad.

* InLoveWithTheMark: Possibly. It's left to audience interpretation whether [[spoiler:Martin fell in love with Minerva or was using her and Finn for free meals and a bed to sleep on.]]

* NeverMyFault: When Finn finally asks why he was left in the forest, Martin gets incredibly defensive and suggests that "maybe ''you'' abandoned ''me'', did you ever think of that?!" -- Finn was a toddler, and this seems to prove to him that Martin might not be such a good guy after all.

* ButNowIMustGo: After restoring the powers of the ice crown to keep Simon alive, she decides to leave the Ice King until she is able to find a way to safely free him.

* PowerBornOfMadness: Theorizes that all Magic Users have Magic, Madness, and Sadness. Confirmed when she screams and teleports away upon getting Magic Man's magic.
** Foreshadowed in her cameo in "Jake the Brick" when she was looking at a paper with "M+M+S" on the top.

* StableTimeLoop: She left Simon when he became the Ice King because the Simon from the future was saying goodbye to her through a PortalToThePast; thus she jumped through it to be with him there.

* TheUnfettered: [[spoiler:In Elements Part 8, she is shown to be willing to do ''whatever it takes'' to have Simon back to normal, even if it means going back in time to destroy the crown, potentially averting the Mushroom War, and cause all of Ooo to be RetGone in the process of altering history, not caring about the consequences that might come out of it.]]

* DemotedToExtra: [[spoiler:After three years since the finale, she finally makes a comeback in the ''Distant Lands'' special "Wizard City"... as a background character, only appearing for two seconds. It happens again in ''WesternAnimation/AdventureTimeFionnaAndCake'' despite Finn mentioning her a few times, she only appears in "Prismo The Wishmaster" when Prismo looks through Ooo for a few seconds.]]

* PutOnABus: The creators confirmed that he wouldn't return in the "Distant Lands" miniseries besides a hallucination of his skeleton and a memory of him possessed by the Lich. Similarly, he doesn't appear at all in the "Fionna and Cake" miniseries.
