History AdaptationalVillainy / WesternAnimation

* ''WesternAnimation/StrawberryShortcake'': The character Raspberry Tart/Torte is usually a friend of Strawberry in most incarnations; in the 2021 series ''Berry in the Big City'' however, she is changed into an AlphaBitch and Strawberry's SitcomArchNemesis who is jealous of her business.

* ''WesternAnimation/Invincible2021'': Nolan aka Omni-Man gets a massive dose of this in the finale. Yes in the comic he killed the Guardians of Globe, destroyed a city while fighting Mark and initially intended to enslave Earth for [[TheEmpire Viltrum]] too -- but he was still deeply reluctant to betray his family and the world he spent so much time on. Ironically in the comic Nolan was still saving innocent lives as a superhero right up until one of Guardians of the Globe Immortal Man attacks him in revenge and Nolan takes him down in front of Mark, forcing Nolan to drop the act and reveal his true intentions. In the show Nolan's TragicVillain nature is offset by his brutality and cruelty being dialled up as once Debbie learns the truth and leaves him, he immediately starts murdering people and while fighting Mark, Nolan (unlike the comic) [[ForcedToWatch purposely kills]] civilians his son vainly tries to save. The show's Nolan even puts Mark in the path of a speeding train just so all the passengers can get [[{{Gorn}} gorily]] torn apart all over him, something comic Nolan didn't do (and would never do) to his son. He does ultimately regret hurting Mark, but much more after the fact than his comic counterpart.

* In ''WesternAnimation/DCSuperHeroGirls2019'', Dex-Starr of the ComicBook/RedLanterns plays up CatsAreMean and is just evil [[ForTheEvulz for the sake of being evil]] as opposed to his DarkAndTroubledPast in the comics. While in the comics he was an AntiHero who preferred to PayEvilUntoEvil, this version of him HatesEveryoneEqually and sought to burn the world just because he could.

* ''WesternAnimation/TeenTitans2003'':
** In the comics, while some writers portray Deathstroke as a NobleDemon, more often he's portrayed as a ruthless killer who really ''is'' as evil as he seems, but he does consistently have a few redeeming qualities (his friendship with Bill Wintergreen, his love for his children [[AbusiveParents even when he's not a very good father to them]], and occasionally shows disgust for people worse than him. Ain't ''none'' of that in this show; Slade doesn't have a single redeeming quality in the show and is even willing to help Trigon create HellOnEarth as long as he benefits, and only turns against Trigon when the demon refuses to honor their agreement.
** Blackfire in the comics was shown to genuinely care about her people, eventually came to regret her horrible treatment of Starfire, and it was later revealed that she treated Star as badly as she did because she blamed her for the death of their brother. Blackfire in the series is a JerkWithAHeartOfJerk who doesn't care about her people at all, never regrets anything she does to Star, and only torments Star because the people of Tamaran love Star more than her, [[spoiler:and the tie-in comics reveal that in the show's continuity, Blackfire sold their brother into slavery]].

* ''[[WesternAnimation/UltimateSpiderMan2012 Ultimate Spider-Man]]'':
** The series depicts ComicBook/{{Morbius}} as a willing member of terrorist organization ComicBook/{{HYDRA}}, when he is an anti-hero in the comics.
** In the comics, Eddie Brock becomes Anti-Venom, who was a [[EvilCounterpart Good Counterpart]] to the third Venom. Here, Anti-Venom is a creation of Dr. Octopus who is an EvilCounterpart and ManOfKryptonite to Agent Venom.

* ''WesternAnimation/XMenTheAnimatedSeries'': Bella-Dona gets a great deal of this in "X-Ternally Yours". In the comics she's somewhere between an AloofAlly and an AntiVillain, she genuinely loves Gambit having been engaged to him since they were children and was heartbroken at him having to leave her due to friction between their Guilds and even more upset upon learning Gambit had found a new love in Rogue. While she does have villainous traits and has done evil things (such as orchestrating Rogue's FirstLove Cody's death out of revenge for Rogue taking her memories) she still [[IJustWantMyBelovedToBeHappy gracefully accepts]] she's lost Gambit and moves on. The show keeps Bella-Dona's backstory, but chucks out all her redeeming qualities as upon meeting Gambit again she puts a [[AgonyBeam painful]] PowerLimiter ring on him and swears that [[{{Yandere}} he'll never escape her again]]. Then when Rogue shows along with Wolverine and Jean to save Gambit, Bella-Dona drops everything to try and [[MurderTheHypotenuse right kill her rival on the spot]] screaming that Gambit is hers. She also wants to destroy the Thieves Guild here, unlike the comics where she just wants to the Assassin and Thieves Guilds to combine.
* ''WesternAnimation/XMenEvolution'':
** Colossus and Gambit were members of [[Characters/MarvelComicsMagneto Magneto]]'s Acolytes, despite being actual members of the X-Men in the comics. They eventually pulled a HeelFaceTurn and were seen as part of the team in the epilogue. That said, Colossus is only a member of the Acolytes because Magneto is threatening his family, which also resulted in this being crossed with AdaptationalHeroism on his part.[[note]]Granted, Colossus would rejoin the X-Men later, but he also briefly part of the Acolytes in the comics during the events of ''ComicBook/{{Fatal Attractions|MarvelComics}}'' -- except there, his defection was ''willing'' on his part, due to Illyana dying from the Legacy Virus early on and it triggering a disillusionment within him of Xavier and his death of co-existence.[[/note]]
** [[Characters/MarvelComicsQuicksilver Quicksilver]] and Characters/ScarletWitch are only in the Brotherhood in the comics because Magneto saved him and they felt they owed him, leaving upon realizing how horrible he truly was. In the show, Pietro is a bit of a sociopath and Wanda suffers from a number of mental issues.

** Hera is a complicated case, she's far from a benevolent Goddess in Myth/ClassicalMythology being the embodiment of WomanScorned as she dispenses MisplacedRetribution on the innocent women Zeus slept with and gave Hercules quite the TraumaCongaLine, before he saved her life. In the show however, Hera is the BigBad proper as she tries to use the Giants to conquer Mount Olympus and kill Zeus, something she'd never do in the Greek Myths. Compounding issues further is that Zeus gets a much more [[AdaptationalNiceGuy positive]] [[AdaptationalHeroism portrayal]], especially in regards to his mortal affairs which are [[AdaptationalConsent consensual and loving]], making Hera's MurderTheHypotenuse to Electra [[ForcedToWatch in front]] of Zeus and later tyranny even more disproportionately [[KickTheDog cruel]] and [[AxCrazy insane]]. Also unlike the Myths she treats other Gods such as Hermes horribly, making her all the more unpleasant.

** Hector in his debut game ''VideoGame/CastlevaniaCurseOfDarkness'' is TheHero, once a Forgemaster of Dracula he became a DefectorFromDecadence and escaped back to humanity before Isaac tracked him down and killed his wife, sparking Hector's RoaringRampageOfRevenge. In the show Hector is a much less heroic character, as he is depicted as MisanthropeSupreme due to childhood abuse, who suggests they cull mankind putting humans in PeopleFarms as an alternative to KillAllHumans. While he does betray Dracula in this version... he betrays him for the TheStarscream Carmilla and becomes her team's Forgemaster (albeit very unwillingly). Ironically his counterpart from the game Isaac gets the reverse treatment going from a one-note asshole psychopath to compelling and sympathetic AntiVillain. [[spoiler: Averted in Season 4 where Hector manages to [[TheAtoner redeem himself]] and helps bring down Carmilla]].

** Series/TheBananaSplits are once again antagonists, but this time they're a lighthearted group of petty criminals instead of bloodthirsty HostileAnimatronics like [[Film/TheBananaSplits the live-action film]].
