History AdventureTime / TropesAToC

** Though voiced by [[Creator/NikiYang a woman,]] BMO has no fixed pronouns. "BMO Lost" has BMO & a bubble who sounds like a man taking care of a baby together, at the end, [[spoiler:BMO & Bubble decide to get married.]] The bubble is likely also genderless.

*** In "Jake the Brick," he's seen to own a copy of ''Buff Wizards'' magazine.

** Prismo is a pink LivingShadow with a lisp and an occasional limp wrist who is overjoyed when Jake tells him he loves him. When he and Jake are sitting in the hot tub talking about relationships, he says he doesn't want to be in a relationship because he "Doesn't want to have to talk about everything for hours before doing it", and Jake even remarks that he has a very bleak view on relationships. It helps that his "reasons" show that he's clearly never really dated a woman before. And then there's the "Call me" letter he gives to Jake at the end of the episode.
** Huntress Wizard competed for Princess Bubblegum's kiss as well. She's brought into AmbiguouslyBi, however, as she's Finn's third love interest. They're never shown breaking up and by the end of the show it remains ambiguous whether or not they're still a thing.
** Both of the Lemongrabs. They live together, have no problem with hugging while they're butt naked, have many children, love each other very much, "keep each other company in lemony bliss," and insist that Princess Bubblegum "call first" before visiting. They refer to each other as "brother", which does not necessarily reduce the ambiguity.

** Although the "ambiguous gayness" of Bubblegum and Marceline gets less questionable in later seasons.

** In [[ForWantOfANail Farmworld]], Finn's baby sibling is naked, but of course we never see anything. Farmworld Finn only addresses the kid once, as "Younger Sibling."

* AnAesop: Sometimes subverted, e.g. in "Freak City" and "Witch's Garden"", but often played completely straight, albeit in weird ways. For example, Finn is taught not to break promises by being punished by the Gumball Guardians.

* BrokenAesop: Let's just say this show doesn't take the whole AndKnowingIsHalfTheBattle thing too seriously.

* CluelessAesop:
** The moral of "Conquest of Cuteness" is that using your cute looks and charm to manipulate others is better than using violence.
** The moral of "All Your Fault" is that having more children than you can feed will create hardship for your family and community.
** "Tree Trunks" suggests that you shouldn't encourage people to "follow their dream" if they simply don't have the necessary characteristics for it, as it will probably lead to disappointment or something even worse.
* [[ClusterFBomb Cluster-F Bomb]]: Obviously we can't have literal F-Bombs in a kids show but Simon repeatedly shouting "MOTHER!" while angrily kicking at a car has all the hallmarks of this trope. He even asks Marceline to cover her ears before he starts cursing.

** For some, Magic Man's history with his girlfriend. He obviously cared for her dearly, and misses her a great deal. Only in those moments was he portrayed as a human, hurting character.

* ApocalypseHow: The Great Mushroom War, the scale being Planetary Societal Collapse, or possibly Planetary Species Extinction. There is certainly a lot of evidence of a [[PostApocalyptic Post Nuclear Apocalyptic]] setting [[NuclearOption (like missile shells and such)]]. If this is the case, then the War definitely caused a {{Depopulation Bomb}}. This is pretty much confirmed and gets some bits of Continental Physical Annihilation added in Season 4. In "Sons of Mars" we get a brief view of the Earth from space. There's a large chunk of the planet missing. Also, Princess Bubblegum's holographic diagrams in "Burning Low" shows a rotation of the Earth in the bottom left corner of the screen.

* AdventureFriendlyWorld: The world had suffered from an apocalypse about 1000 years ago due to a nuclear war and the return of magic, and still hasn't quite recovered. Civilization is limited to small, sporadic kingdoms, and the rest of the world is filled with ruins, ancient dungeons, monsters, etc, perfect for any young adventurers out there.

* AbsurdlySharpBlade: Finn's second and third swords. The second sword can cut wood like hot butter, while the third is a family heirloom crafted from demon blood, and can cut through diamonds. [[spoiler:His fourth sword, the [[KatanasAreJustBetter Grass Blade]], is sharp and precise enough to cut the image of his face into something as small as a price tag. As well as being sharp enough to destroy fear itself (by slaying the Fear Feaster at the end of "Billy's Bucket List."]]
** [[spoiler:Once it becomes Finn's arm in season six, it continues this tradition, coming to life whenever it feels Finn is threatened--even to slice up [[EldritchAbomination Orgalorg.]]]]
* AccidentalMisnaming: Tree Trunks keeps referring to Lemongrab as "Lemon Carb". This is not malicious, but more an indication of her borderline senility.

** The most famous and yet not used anymore is the TitleDrop (Jake asking ''"[[{{Tagline}} What time is it?]]"'' with Finn answering ''"ADVENTURE TIME!"''). Prior to disappearing after the three seasons, it was played straight at first, then {{parodied|Trope}} (''"Party Time!", "Launch Time"''), {{subverted|Trope}} (''"You know what time it is?" "...Adventure Time?"'') and even {{referenced|By}} in ''WesternAnimation/{{Futurama}}'' (''"[[Creator/JohnDimaggio Time for]] [[ActorAllusion you to]] [[ActingForTwo shut up!]]"'').

** Subverted with the Ice King. He appears fat with his robes on, but in "What is Life?", he is revealed to be very skinny, but with [[TopHeavyGuy an abnormally large chest]]. In "I Remember You", he's fattened up to typically normal proportions, but he only lifts his robe to specifically talk about how he's been working out for his chest.

* AlasPoorVillain: The Ice King in "What Is Life?"
** Also the Ice King in "Princess Monster Wife."

** Simon slowly and consciously losing his sanity as he transforms into the Ice King. By the end of the process, he can no longer remember his former life and is rendered deformed, chronically depressed and [[WhoWantsToLiveForever immortal]].

* AndNowYouMustMarryMe: In pretty much every early episode involving the Ice King.

** [[spoiler:The Ice King's Crown]] is revealed to be this in "Holly Jolly Secrets".

* AttackItsWeakPoint:

* CerebusRetcon: In the original short, Abraham Lincoln appeared as the king of Mars. At the time, this was just the height of SurrealHumor. In "Son of Mars", it's revealed that this is actually supposed to be the same person as our Abraham Lincoln, and the reason he's dead in our universe is because he traveled back in time and was killed there.

* CatchPhrase:
--> '''Finn:''' What time is it?\\
'''Jake:''' Adventure Time!
--> '''Shelby:''' CHECK PLEASE!
--> '''Root Beer Guy:''' Bingo bango.

** In "BMO Noire", Finn and Jake go to a party, leaving BMO alone. When they return, Jake has lipstick all over his face and an arrow in his head, and Finn is carrying a dead Sea Lard. It isn't until nearly 30 episodes later, in "Princess Potluck", that we see the other side of this.

** Lemongrab started as being an obsessive NeatFreak with SuperOCD and just a slightly crazy {{Jerkass}}. However, his obsessive cleanliness seems to have been abandoned, and his [[{{Flanderization}} insanity has been amped up to absurd levels.]]

** In a fun subversion, Death's favorite music is [[IncrediblyLamePun Death Metal.]]

* BewareTheNiceOnes: Aside from the fact that both Bubblegum and Finn can get a little... [[NightmareFace iffy]] [[CuteAndPsycho when provoked]], apparently the possessor of the most evil soul in Ooo is [[spoiler:[[EverythingsBetterWithPenguins a Gunter]]. And sure enough, one later almost takes over the Candy Kingdom on its own. That's before we get the reveal of this]]

** In "The Red Throne", Flame King (voiced by Creator/KeithDavid) and Don Jon (voiced by Wrestling/RoddyPiper) have a lengthy fistfight as a reference to ''Film/TheyLive''.
