History TeensAreMonsters / WesternAnimation

* ''WesternAnimation/BeavisAndButthead'': Both [[Characters/BeavisAndButtHeadTitularCharacters Beavis and Butt-Head]] act in such a way that it's easy why one can see them as total assholes, while with [[{{Delinquent}} little respect for authority]].

* Mac's 13-year-old [[BigBrotherBully older brother Terrence]] in ''WesternAnimation/FostersHomeForImaginaryFriends''. In the pilot (along with Duchess), he and her plan to kill Bloo, and most of his life is devoted to making Mac's a living hell. Additionally, while children typically make cute, friendly [[{{tulpa}} imaginary friends]], teenagers more often than not produce destructive {{kaiju}}.

* The ''WesternAnimation/SouthPark'' episode "[[Recap/SouthParkS25E5HelpMyTeenagerHatesMe Help! My Teenager Hates Me!]]" features a group of teenagers that play at an air-soft field. They are all portrayed as vindictive, foul-mouthed, aggressive, and self-centered, ticking off all the boxes for negative stereotypes of teenagers. Gerald even tells his son Kyle that the brain of a teenager is equivalent to the brain of a psychopath.

** [[Characters/AvatarTheLastAirbenderPrincessAzula Princess Azula]] is nearly the lone exception to an otherwise {{subverted|Trope}} rule. [[spoiler:She's the one prominent teenager in the entire show that starts and remains evil from beginning to end. However, she ends up being exposed as a very tragic, messed-up person, so not many people in-show or out of it tend to see her as a "monster" anymore.]]

* ''WesternAnimation/MyLifeAsATeenageRobot'':
** Britt and Tiff (aka the Crust Cousins).
** Brad, Jenny, and Sheldon toward Tuck on multiple occasions.

* ''WesternAnimation/{{Amphibia}}'': [[Characters/AmphibiaSashaWaybright Sasha Waybright]] is a thirteen-year-old ManipulativeBitch who delights in commanding people around and being in charge. [[spoiler:She drops this trope after her CharacterDevelopment.]]

** Robbie is portrayed like this for most of the series, and not just because of his rivalry with Dipper over Wendy's affection (which is ridiculous anyway due to Dipper’s age). In "Fight Fighters" he forces Dipper to fight him, even though Dipper is ''12 years old'', and acts like a brooding jackass almost every time he appears. He finally mellows out somewhat when he begins dating Tammy in "The Love God".

* ''WesternAnimation/{{Velma}}'': [[Characters/VelmaTitularCharacter Velma Dinkley]] grew from being an EnfanteTerrible to this in her teen years. She constantly shows herself to be a cruel, selfish, vengeful, and mean-spirited person who uses her so-called friends as pawns, is a bigot towards anyone she views as more popular or privileged than her, and has a huge LackOfEmpathy for everyone else's problems. [[spoiler: Her most noted examples of her status is when she is the only one shown happy that Fred's Mom/Victoria Jones was killed by stalactite was hit by Norville's bullet and impaled her. All she cared about is that she "solved" the mystery and not the fact that Fred had to see his mother die so horribly, even if she was trying to remove his brain. Also she locked her father, his girlfriend, and her half-sister (who is a baby) out of the house so she could live with her mom only.]]

* ''WesternAnimation/BeavisAndButthead'': Both of the main characters act in such a way that it's easy why one can see them as total assholes, while with [[{{Delinquent}} little respect for authority]].

However, she ends up being exposed as a very tragic, messed-up person, so not many people in-show or out of it tend to see her as a "monster" anymore.]]

** The next most prominent example is [[WellIntentionedExtremist Jet]], who attempts to ''kick an old man in the head'' and flood a whole village of innocents in his intense rage towards the Fire Nation. He's the leader of a gang of teenagers willing to commit murder and other dark crimes for no other motivation than revenge and gets called a monster in-universe by [[TeamMom Katara]]. He's changed his approach by the next time we see him, insisting that nobody else will get hurt when he tries to expose two firebenders disguised as Earth Kingdom refugees, but is forced to learn that [[spoiler: RedemptionEqualsDeath]] when his plan backfires on him.

** Caprice tends to be this out of the teenagers despite that she's not always evil. She can be cruel to her siblings like putting them to dangerous or graphic photo-ops so she can earn social media attention, and also towards her adoptive teenage cousin Cordless. She runs away from her family to live with her rich uncle and aunt (and risks replacing Cordless as their child), develop an autobiography of her new life and insulting her family and best friend Cassandra (after failing to read and respond to Caprice's text messages asking her to join) in one episode. She also dislikes animals and hurts them prominently in at least two episodes.

** [[Characters/MiraculousLadybugChloeBourgeois Chloé Bourgeois]] is a [[SpoiledBrat spoiled]] AlphaBitch who uses her status as the mayor's daughter to [[ItsAllAboutMe have her way]] while harassing those beneath her like Marinette Dupang-Chang. She had a few PetTheDog moments in earlier seasons, but {{Flanderization}} sets in the Season 3 finale and she relapses into this trope. Overall, she's spiteful, mean, couldn't care less about anyone besides herself, repeatedly abuses her peers and family, and [[spoiler:willingly teams up with Hawk Moth over petty reasons]]. She get much even worse as the fourth season begins, especially after being influenced by Lila Rossi.
** 13-15-year-old NewTransferStudent [[Characters/MiraculousLadybugLilaRossi Lila Rossi]] is a ConsummateLiar and BitchInSheepsClothing who outdoes and "mentors" Chloé in being horrible -- come "Revelation" and "Confronation", "Lila" turns out to be a false identity as she weaseled her way into other families under aliases and manipulates Chloé before abandoning her once getting what she wanted from their arrangement.
** Félix Fathom, Adrien's [[UncannyFamilyResemblance identical cousin]], is a Justified case since he was tormented by his dying father over the truth of his existence and forced to do things against his will. This made him into a JerkWithAHeartOfJerk and WellIntentionedExtremist who played a long game with his uncle Gabriel, whom he later learns is Hawk Moth and exploits at the cost of further endangering Paris.

** Two episodes featured the Smith family, one member of which was their angry teen son Bud. The first episode, Bud's entire appearance consisted of him yelling something typically teenagerish at his father, such as "I hate you!" and "No one understands me!" The second episode, which features the entire family as villains, provides every member of the family with a motivation for why they hate the Powerpuff Girls -- and Bud's is "I hate everything!"

** Félix Graham de Vanily, Adrien's [[UncannyFamilyResemblance identical cousin]], poses as him to try and ruin his friendships [[EvilIsPetty for no apparent reason]], and ''also'' tries to throw his lot in with Hawk Moth over a similarly petty goal as Lila (even though [[DramaticIrony he's doomed to fail]], as [[spoiler:he's planning to steal Gabriel Agreste's wedding ring, and Gabriel ''is'' Hawk Moth]]). At the end, he shows [[JerkWithAHeartOfJerk at best fake remorse for his actions]], and [[spoiler:still steals Gabriel's ring]]. And that's without getting into his actions in the season 4 finale, which saw him [[spoiler:willingly betray the heroes to Hawk Moth for his own selfish motives]].
** AlphaBitch Chloé had a few PetTheDog moments in earlier seasons, but by the end of season 3 {{Flanderization}} set in and fully turned her into this trope. Overall, she's spiteful, mean, couldn't care less about anyone besides herself, repeatedly abuses her peers and family, and [[spoiler:willingly teams up with Hawk Moth over petty reasons]].

** [[JerkJock Kevin]], who is 15-years-old[[note]]according to the writing staff[[/note]], often torments and humiliates the Eds (especially Eddy) for [[ItAmusedMe his own amusement]]. He does have his PetTheDog moments, though.

* ''WesternAnimation/EdEddNEddy'': The Kanker Sisters are [[BarbaricBully Barbaric Bullies]] indicated to be teenagers. Lee, the oldest sister, is easily the worst of them.

* ''WesternAnimation/TheWackyAdventuresOfRonaldMcdonald'': ''Scared Silly'' plays the trope for laughs at the end of the live-action FramingDevice, where Ronald [=McDonald=]'s dog Sundae is watching a sequel to the dinosaur movie he was viewing in the beginning and explains to Ronald that the sequel involves the baby dinosaur from the first film becoming a teenager with an appetite for destruction.
