History Characters / AdventureTimeOtherCharacters

* AmbigiousSituation: [[spoiler:Whether Martin's {{jerkass}} behavior in the present is a result of his head injury and memory issues or him simply choosing to burn bridges after he believed his son died and returning to old behavior is ultimately up to the viewer to decide.]]

* TheGreatestStoryNeverTold: [[spoiler:As ''Islands'' reveals, Martin left with Finn not to kidnap him or anything malicious, but because the consequences of his past were catching up to him and during his brief escape with Finn, he fully intended to tell Minerva he was coming back, only for the GuardianEntity to show up and attack them due to thinking they were leaving. Martin promised Finn he'd be back for him before jumping off to successfully injure the entity, but the resulting explosion injured Martin and sent Finn to the shores of Ooo. Because it is impossible to have witnesses for this, Minerva and Finn believe that he simply took Finn for reasons unknown and then abandoned him,]]

* {{Irony}}: [[spoiler:His last interaction with Finn is accepting Martin will never change, with both parties seemingly ignorant that Martin had changed immensely 16 years earlier for both Minerva and his son.]]

* DirtyCoward: His first instinct is always to save his own (worthless) skin, and only his.

* HeelFaceDoorSlam: [[spoiler: Martin seemed on his way to becoming a better person during his time with Minerva, even making an honest living as a barber, but after getting separated from Founder's Island and suffering a head injury, he seemed to go back to his old, dishonest ways.]]

** 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.]]

* KarmaHoudini: [[spoiler:After all he did, he gets to ascend to another mode of existence along with the Catalyst Comet. Though it's later implied to be an unintentional redemption as the kind of person he used to be.]]

* AmbiguouslyGay: Prismo's pink-colored, he talks with a slight lisp, and he tends to chill in a hot tub with his guy-friends Jake and the Cosmic Owl. One topic of discussion in his room is him finding a girlfriend, which he awkwardly hems and haws over. He is also overjoyed when Jake casually claims he loves him. [[spoiler:He's also very depressed after Jake's passing, complete with stubble and eyebags.]]

* PointyHairedBoss: He completely ignores Scarab's report that Prismo has created an unauthorized universe because [[ScrewTheRulesIHaveConnections he thinks Prismo is cool]]. He even ''[[DontMakeMeDestroyYou physically threatens]]'' Scarab when for refusing to drop the matter.

[[folder:General]]

* CelestialBureaucracy: An especially corrupt and dysfunctional one. [[TheGodsMustBeLazy Gods regularly neglect their duties or abandon their posts altogether]], [[TheUnchosenOne give special treatment to mortals they like]], [[ItsPersonal hold vendettas]], engage in practices like {{nepotism}} and sometimes even [[TheUsurper try overthrowing each other]]. [[spoiler:It's so bad the system has to employ [[SpacePolice "god-auditors"]] whose sole responsibilities are keeping other gods in line and even then they can be just as corrupt like Scarab when he shirks his duties to pursue Fionna, Cake and Simon in order to take Prismo's position as Wishmaster. The TopGod in charge is Prismo, Scarab and Orbo's mysterious boss.]]
* CosmicEntity: They are this and nearly everything under both it and all DivineTropes.

* CelestialBureaucracy: An especially corrupt and dysfunctional one. [[TheGodsMustBeLazy Gods regularly neglect their duties or abandon their posts altogether]], give special treatment to mortals they like, [[ItsPersonal hold vendettas]], engage in practices like {{nepotism}} and sometimes even try overthrowing each other. [[spoiler:It's so bad the system has to employ "god auditors" whose sole responsibilities are keeping other gods in line and even then they can be just as corrupt like Scarab when he decides to shirk his duties to pursue Fionna, Cake and Simon in order to take Prismo's position as Wishmaster. The TopGod in charge is Prismo, Scarab and Orbo's mysterious boss.]]

* BewareTheNiceOnes: He's rather affable but even Scarab knows better than to tick him off.

* PointyHairedBoss: He completely ignores Scarab's report that Prismo has created an unauthorized universe because [[ScrewTheRulesIHaveConnections he thinks Prismo is cool]]. He even ''[[DontMakeMeDestroyYou physically threatens]]'' Scarab when the auditor refuses to drop the matter.

[[folder: "The Boss"]]

* ReasonableAuthorityFigure: They're willing to extend Scarab one last chance to apprehend Fionna and Cake when he claims that he is just trying to do his job. When it becomes clear Scarab was actually acting out a personal grudge they strip him of his god auditor position and demote him to being Prismo's assistant, which is notably more mild than the punishment [[DisproportionateRetribution Orbo]] had in mind.

** Red four-sided pyramids (or diamonds when viewed from the top) appear to have some sort of unspecified significance and show up most prominently on top of GOLB's head, on the top and bottom of Grob, Gob, Glob, and Grod's helmet, and Scarab's mask.
** "The Boss" is represented by a golden cord phone with angel and devil wings and two stars on the back.
* CelestialBureaucracy: An especially corrupt and dysfunctional one. Gods regularly neglect their duties or abandon their posts altogether, give special treatment to mortals they like, hold vendettas, engage in nepotism, and sometimes even try to overthrow each other. It is so bad that the system has to employ god auditors whose sole responsibility is keeping the other gods in line and even then the god auditors can also be just as corrupt like Scarab when he decides to shirk his duties to pursue Fionna, Cake and Simon in order to take Prismo's position as the wishmaster. The TopGod in charge of the whole system is Prismo's mysterious boss.

** [[spoiler:He does another one along with the Cosmic Owl when Betty says that she's going to rewrite history to prevent the Mushroom War from happening.]]

* ScrewTheRulesIHaveConnections: Inadvertently. He himself isn't the type to pull strings in his own benefit, but other cosmic entities vouch for him as a "cool guy" so much that his ''actual'' wrongdoing is damn near overlooked. Scarab has plenty of trouble trying to nail him for unauthorized universe creation because ''his'' boss, Orbo, likes Prismo enough to be utterly convinced he'd never do that (and physically ''threatens'' Scarab to drop the issue).
* SenselessSacrifice: He allows Finn and Jake to wake up his human form, thus destroying his Wishmaster form. He did that so Finn could be sent to the Citadel to meet his human father... who was a manipulative {{Jerkass}} extraordinaire, and had no interest on Finn at all. Even worse, he failed to realize that the Lich would kill him after he woke up, meaning that [[spoiler:without plan B]] he'd be dead for good, as opposed to coming back when his host goes back to sleep.
* StableTimeLoop: He's able to avert this without consequence, allowing Jake to avert the Lich's wish to destroy all life, even when that lead to Jake's wish. Possibly justified due to being a deity.

* FertileFeet: Plants grow wherever she walks. When she kisses Death's cheek, flowers grow, which naturally wilt instantly.
* ItsAllAboutMe: She only agrees to help stop New Death after she finds out that his demolishing of the Dead Worlds will get in the way of ''her'' purpose.
* MarriedToTheJob: She states as much herself, saying that she cares for her job as opposed to her family. She refers to the process of reincarnation as her entire purpose, and it being cut off drives her to create a weapon for Finn and Jake that can kill New Death.

* OffingTheOffspring: [[spoiler:Though she doesn't do the deed herself, she creates the Kiss of Life to kill her own son, in retribution for what he did to his father and his attempt to stop reincarnations.]]

* SnakePeople: As mentioned above, her head is composed of two snakes, making her an odd version of this trope.
* VoiceOfTheLegion: Her heads speak simultaneously, creating this effect.

* TopGod: Is deemed this out of all known celestial-based beings.

[[folder:Scarab ('''UNMARKED SPOILERS''')]]
->Voiced by: Creator/KayleighMcKee

A god-auditor with a grudge against Prismo who attempts to discredit him by revealing the existence of Fionna and Cake's reality. He is later demoted to being Prismo's assistant for abandoning his post to erase the rogue universe and attempting to destroy it himself once it was deemed authorized.

* BadassInANiceSuit: He rocks a tuxedo and tie while proving himself capable of taking down mortals and wayward entities alike.
* BountyHunter: Tracks down beings who have committed cosmic crimes and brings them in for punishment.

* DesignatedVillain: For the most part he's just trying to do his job but serves as the overall main antagonist to Prismo, Simon, Fionna and Cake. Ultimately {{averted}} at the very end.
* DidYouJustFlipOffCthulhu: Explicitly tells [[GodOfChaos GOLB(etty)]] not to interfere despite their attachment to Simon; it predictably doesn't end well for him.

* EstablishingCharacterMoment: He finds and captures the entity [[EnergyBeings Kheirosiphon]] for voluntarily leaving his post to become a [[HumanDisguise tea shop owner]] and is quietly pleased when he notices Prismo on [[TheMostWanted his cosmic hit-list]] for committing a violation.

* HellishPupils: Has them under his retracting face-plates which he can normally reveal when stressed or for intimidation.
* InsectoidAliens: Resembles one in appearance complete with jointed, segmented armor.
* NecessarilyEvil: Used to be when it came to delivering "justice" against [[CosmicEntity higher beings]] who disrupted the CelestialBureaucracy ([[InherentInTheSystem more so than usual anyway]]).
* JerkassHasAPoint: He's right about [[MakeAWish Prismo]] breaking the rules through creating [[AlternateUniverse Fionna and Cake's home universe]] without anyone's knowledge and the effects the duo's travels ultimately had on TheMultiverse from the moment they [[TrappedInAnotherWorld ended up in Ooo]] via [[BroughtDownToNormal Simon]]'s attempt to resurrect [[TheLostLenore Betty]]. Unfortunately for him it falls flat due to only wanting Prismo's GodJob and when he tries taking said universe apart anyway.
* LaserGuidedKarma: Is [[SealedEvilInACan imprisoned in a crystalline orb]] with his own SwissArmyWeapon after doing the same to many others and later made Prismo's assistant.
* MadeOfIron: Survived [[AnIcePerson Winter King]] [[TakenForGranite freezing him in solid ice]], being attacked by a [[AnthropomorphicPersonification physical embodiment]] of both PrimordialChaos and AbsurdityAscendant, having [[TankGoodness an advanced tank]] dropped on him and getting [[NoHoldsBarredBeatdown pummeled]] by Fionna and Cake after they both [[{{Sizeshifter}} grew in size]] and the latter [[VoluntaryShapeshifting turned herself into]] [[DropTheHammer a hammer]]; though that last one [[DentedIron left his armor cracking in various places]].
* RedEyesTakeWarning: Has bright red dots in his eye sockets when not using his FlowerMouth.
* ScarabPower: It's in his name but he does resemble one in appearance and is quite formidable.
* ScrewTheRulesTheyBrokeThemFirst: Pulls this big time after being warned by Orbo and goes off on his own.
* SwissArmyWeapon: As mentioned above he can use it to [[AndIMustScream trap opponents]]; that's not all as it can store and release said foes, provide an advantage in combat, [[RealityWarper alter the existence of reality at will]] and contains a [[TheMostWanted list of targets for him to seek out]].
* ThisCannotBe: When Fionna makes her "unregistered" and {{Depower}}ed universe [[AscendedFanon completely]] [[CanonImmigrant legitimate]] which renders his mission obsolete.
* VillainousBreakdown: [[RoaringRampageOfRevenge Goes ballistic]] despite orders from ''[[TopGod his own real boss]]'' and chooses to destroy Fionna and Cake's universe the old-fashioned way to spite Prismo.

* DangerousDeserter: Is classified as being this in Scarab's criminal database despite just wanting to live out his days serving tea to customers.
* EarnYourHappyEnding: [[spoiler:In the epilogue of ''Fionna and Cake'' he finds work as a waiter at the bakery in Fionna's world after escaping imprisonment and the battle with Scarab is over.]]
* ElementalPersonalities: A fiery being with an equally fiery personality once he drops his mortal disguise.

A high-ranked cosmic entity and Scarab's superior.

* BewareTheNiceOnes: He's rather affable but even Scarab knows better than to tick him off.
* TheDragon: Seems to be this for the TopGod.
* PointyHairedBoss: He completely ignores Scarab's report that Prismo has created an unauthorized universe because [[ScrewTheRulesIHaveConnections he thinks Prismo is cool]]. He even ''[[DontMakeMeDestroyYou physically threatens]]'' Scarab when the auditor refuses to drop the matter.
* ReasonableAuthorityFigure: He summons Scarab before he can finish tracking down Fionna, Cake and Simon. While the audience knows Scarab is right about what Prismo has done Orbo is in the right to judge Scarab putting off his own duties for a seemingly baseless vendetta against Prismo.

* RealityWarper: He grants wishes that can alter the course of history. However even his powers have limits -- he can't bring back those who were killed or assimilated by Golb. Both Magic Man and Simon went to him to try to get Margles and Betty back. Both times Prismo could only conjure a waste-paper basket-ball hoop.

* NoodleIncident: Just how someone like Martin wound up in a cosmic prison that's designed for [[EldritchAbomination Eldritch Abominations]], including ''[[BigBad the Lich]]'', is never touched upon.

* BecauseYouWereNiceToMe: A variant in that he admitted that part of the reason he helped Jake was that he greatly appreciated Jake actively being friendly to him as his only other friend seems to be the Cosmic Owl.

* Hypocrite:He calls out Simon for his grief over Betty to the point of casting a Summoning ritual to bring her back which led to Fionna and Cake being summoned instead. But he is in no position to criticize Simon considering he clearly never got over Jake's death which led to his work performance suffering greatly, messing up Wishes and ignoring calls.

* AscendedToAHigherPlaneOfExistence: Takes up the Catalyst Comet's offer to transform him into a "new mode of existence."

A once populous species who prospered during the era before Ooo. The vast majority of humans were subsequently wiped out or mutated during the events of the Mushroom War and its chaotic aftermath. Despite this, they still manage to persist even a thousand years after their civilization was destroyed. The mystery of their destruction and survival would serve as a major part of the show's backstory, including how Finn was for a long time assumed to be the last human in Ooo.

* AfterTheEnd: The Mushroom War wiped away their civilization and most of humanity with it. By the time of the series, the only known settlement of survivors are an isolationist island cut-off from the rest of the world.
