[[caption-width-right:230: Kaa in the [[Literature/TheJungleBook original]] Jungle Book vs Kaa in Disney's [[Disney/TheJungleBook adaptation]]]]

->''"As many people have noted throughout the years though, [[Franchise/DisneyAnimatedCanon Disney]] has been rather...lax when it comes to adapting books and fairy tales into movies. This is understandable in some cases. Still, it can be a bit galling when one knows that the fire-breathing, demonic witch on the screen was a kindly old lady in the source material."''
-->-- ''[[http://zelda-queen.livejournal.com/46445.html Top Five Miscast Disney Villains]]''

The villain of an adaptation or retelling of a story is a familiar character who wasn't as bad in the source material. Sure, they may have been [[{{Jerkass}} a bit of a jerk]], or [[TrueNeutral couldn't care less about the good guys]], but they weren't ''evil''. Maybe they were even an ally of the main characters who [[TokenEvilTeammate leaned a little too far on the evil side]], or a villain [[EvenEvilHasStandards with standards]] or who was [[PetTheDog known to show a softer side]]. Maybe the character [[SitComArchNemesis rubbed the heroes the wrong way]], but never caused any real harm and was otherwise a decent person. In any case, the character ''seriously'' TookALevelInJerkass in the POVSequel, TheMovie, TheFilmOfTheBook, or any other reimagining of the original material. Where they were simply a pest before (and never treated as anything worse than that), or even friendly, they now [[KickTheDog kick dogs]] [[ForTheEvulz for fun]].

This trope can take several forms, depending on the adaptation and the character. The TrueNeutral figure is actively villainous instead of simply not caring or choosing not to get involved. An imposing and potentially dangerous, but ultimately helpful, ally may become an enemy instead. The AntiVillain and TragicVillain will probably lose most or all of their sympathetic side and have fewer, if any, [[PetTheDog nicer moments]]. The {{Jerkass}} companion who is [[HateSink merely contemptible]] (but still entitled to the same protection as any other non-villain) in the source material will start committing acts in the adaptation that make them an actual enemy. The dangerous but tragic WoobieDestroyerOfWorlds will lose any sympathetic parts of their characterization or backstory, and the NobleDemon will lack most or all of their [[EvenEvilHasStandards code of honor]]. Meanwhile, the WellIntentionedExtremist's belief that they are [[KnightTemplar doing the right thing]] is gone, and they do evil things just ForTheEvulz, even [[CardCarryingVillain saying so]]. Sometimes it can be as simple as ignoring a reformed character's HeelFaceTurn or TheAtoner's remorse over their past bad behavior. An UnintentionallySympathetic character or a DesignatedVillain in the source material may also be given a KickTheDog moment or two to make the character more obviously vicious and prevent the audience from feeling too sorry for them.

This occasionally happens to characters who were explicitly good guys in the source material, and if it does, it's sometimes a TakeThat [[TakeThatScrappy an unpopular one]] or to make the character DarkerAndEdgier. It may be a sign of CharacterExaggeration. It can also be done [[NotHisSled to preserve a twist]] in the original story by surprising the audience with the identity of the villain, using an unexpected character as opposed to the original villain, who turns out to be innocent in the adaptation.

[[TropesAreTools This isn't always a bad thing]], however, and indeed some iconic villains have come about in this way, although it will probably lead to accusations of AdaptationDecay or CharacterDerailment from purists. Sometimes is the result of CompositeCharacter - the composite mixes the harmless character and a more villainous one - or AdaptationExpansion, when [[NoAntagonist there is no obvious villain]] in the original work, and a [[TheGhost Ghost]] or another minor character [[AscendedExtra gets the part]]. Sometimes it's to [[LighterAndSofter make the moral lines of an otherwise edgy story]] [[BlackAndWhiteMorality more clear]] or to [[AdaptationDistillation simplify]] a complex character. A PerspectiveFlip often uses this deliberately along with AdaptationalHeroism to subvert the audience's expectations of who the hero and villain are. If the adaptation does well, the darker incarnation of the character may become more popular and [[AdaptationDisplacement eventually overshadow the original]], for [[EvilIsCool a variety]] [[DracoInLeatherPants of reasons]].

It's not Adaptational Villainy if [[CanonForeigner an entirely new character]] is created to be the villain. This trope only applies if the villain in question is recognizable from the original work, but was [[AntiVillain a more sympathetic]] or [[TragicVillain tragic]] figure, had [[EvenEvilHasStandards some form of standards]] or sympathetic motivations, had [[PetTheDog sympathetic moments]] or [[MoralityPet people that the villain genuinely cared about]], was strictly neutral, was eventually [[HeelFaceTurn redeemed]], [[TheAtoner showed remorse]], or wasn't evil at all. It is also not Adaptational Villainy if a character is [[{{Flanderization}} Flanderized]] into being more outright evil than they originally were within a canon, their original, more understandable motives behind their actions are [[MotiveDecay downplayed or completely ignored as the material goes on]], or if constantly switching sides is [[HeelFaceRevolvingDoor an established character trait]].

This trope is OlderThanDirt, since this sometimes happened to religious or mythological figures who, over time, became more malicious than they were in the older versions of their myths due to displacement or conquest, hence the SuperTrope {{Demonization}}. Also a subtrope of AdaptationPersonalityChange. Compare EverybodyHatesHades, which is this trope applied to certain DarkIsNotEvil gods in mythology, and HistoricalVillainUpgrade, which is a variant for RealLife figures. RonTheDeathEater happens when a section of a fandom demonizes a character rather than one specific adaptation. Contrast TookALevelInJerkass, in which the character becomes more unpleasant canonically, because of CharacterDevelopment.

[[folder:Fan Works]]
* ''Fanfic/LastChildOfKrypton'': Kaworu's role and personality greatly changes between both versions of the story: while on the original he is forced to fight Shinji via BrainwashedAndCrazy (and before and after the fight he is a very useful ally), the Redux version ''starts'' as a slimy bastard and only gets more horrible as it goes.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfiction:
** While Discord in canon was certainly malicious and powerful, he was presented more along the lines of a misbehaved brat than anything else, and the episode "Keep Calm and Flutter On" demonstrates that [[spoiler:once he's exposed to ThePowerOfFriendship he starts a friendship with [[MoralityChain Fluttershy]] and becomes an occasional helpful, if still jerkish, TricksterMentor]]. However, many fan stories (most prominently the ''Fanfic/PonyPOVSeries'' and Fanfic/TheNuptialverse) present him as an unrepentant monster, responsible for multiple genocides and the GreaterScopeVillain behind many other villains, among other crimes. This ''is'' somewhat more justified for fanfics that were written before "Keep Calm and Flutter On" and the character development Discord got in that episode; later works have less of an excuse.
** Discord gets this '''bad''' in ''FanFic/TheImmortalGame'', where he is almost a full-blown EldritchAbomination who delights in turning ponies into [[BalefulPolymorph hideous monsters]], MindRape, and tricking ponies into committing horrifying acts. [[spoiler:He is responsible (though not willingly) for the FaceHeelTurn of the fic's BigBad.]] His comedic demeanor is significantly toned down, while his nastiness is turned UpToEleven.
** While it's mostly PlayedForLaughs, Princess Celestia gets this a lot. There are memes of her being a tyrant who rules with an iron hoof and sends people to the moon at the slightest annoyance, a Discord-like prankster causing the cast's problems [[ItAmusedMe for the fun of it]], or a MemeticMolester. Look up Tyrant Celestia, Trollestia, and Molestia, respectively. In ''FanFic/FreedomThroughHarmony'', Celestia is corrupt and banished Luna for trying to reason with her. That still does stop her from becoming Nightmare Moon, though.
** In ''FanFic/HarmonysWarriors'', a rather expansive crossover with the Franchise/MarvelCinematicUniverse, many friendly side characters or background ponies are full villains, including Fancy Pants, Snowflake, Cheerilee, Carrot Cake, Fleur de Lis, Gustav, Hoity Toity, and Filthy Rich.
** In the [[WesternAnimation/MyLittlePonyTVSpecials G1 special that he premiered in]], Scorpan was a NiceGuy who happened to work for BigBad Tirac, and in ''Friendship is Magic'' it's mentioned that Scorpan befriended the ponies and helped them imprison Tirek in Tartarus. ''[[FanFic/TheGodEmpressOfPonykind The Warmistress of Equestria]]'', however, portrays Scorpan as a manipulative, bloodthirsty Lord of Chaos whose EvilPlan is to break Tirac out of the Warp and sacrifice Equestria to the Dark Gods.
** In the AlternateUniverseFic series [[Fanfic/RainboomsAndRoyalty The Dashverse]], the canon villains become much more threatening. They aren't too monstrous that the series is grimdark, but they do sink to depths not approachable in canon.
*** In ''Rainbooms and Royalty'', the re-imaging of the pilot, Nightmare Moon assaults and repeatedly tries to kill the Mane 6, especially Rainbow Dash, [[spoiler:[[BrainwashedAndCrazy brainwashes]] Shining Armor and Ditzy Doo into her loyal minions]], and threatened to drop the rest of the Mane 6 to their deaths and forcing Rainbow Dash to [[SadisticChoice choose which ones to save.]] By the end, it is not surprising that Rainbow Dash hasn't forgiven Luna.
*** In ''Hot Heads, Cold Hearts, and Nerves of Steel'', King Sombra, who was ''already'' a CrazyPrepared and evil dictator in canon, kidnaps the foals of Ponyville and brings them to the Frozen North. When Rainbow Dash reaches his lair [[spoiler:he enters Rainbow's head and tells him his backstory: he started out as just as snobbish prince ''before'' he obtained the Alicorn Amulet. Afterwards, he sought even greater power, he murdered his wife, manipulated Luna into falling in love with him, and even after his defeat by the Princesses, he knew he had driven Luna into the despair that would create Nightmare Moon. He then reveals his plan, [[PoweredByAForsakenChild to sacrifice the foals]] to increase his power and become an alicorn god. And he comes pretty damn close as well.]]
** ''Blog/{{Moonstuck}}'' is a weird case, as while [[spoiler:Discord]] is just as nasty as his canon self with the same personality and powers, the comedic traits of the former are strongly downplayed while the latter are played up to almost EldritchAbomination levels, and the fact that he's doing all this to a ''child'' makes his usual antics ten times worse. The character design also helps; while his canon [[spoiler:goofy {{Mix And Match Critter|s}}]] appearance makes him hard to take seriously sometimes, in ''Moonstuck'' he's drawn in a monochrome, overbearing, heavily sketchy style reminiscent of [[Anime/TengenToppaGurrenLagann the Anti-Spirals]].
** In the fanfiction ''Fanfic/SunsetOfTime'', the BigBad Vesper Radiance is a re-imagining of a canon antagonist. For it, she's not only far worse than she was in the canon, she's worse than any of the other villains too. She's ambitious, hungry for power, casually murders (or attempts to murder) several characters, and her ultimate goal is to become a PhysicalGod to rule over Equestria -- after killing off all three Princesses, Twilight and her friends, and anyone else who dares try to stop her.
** In ''Fanfic/TheElementsOfFriendship'', nearly every villain qualifies, as they go from threats dealt with in one or two episodes to powerful threats that need whole {{doorstopper}}s to stop.
*** Trixie flat out cons the town as opposed to simply being a traveling showmare as in canon.
*** [[spoiler: Moondancer is part of an organization working for the GreaterScopeVillain. Justified, as she had not even made an appearance on the show when the series started.]]
** Played for laughs in fanfic series ''Fanfic/EvilBelle'', where for no particular reason, Sweetie Belle decides to become the most feared villain Equesria has ever known. HilarityEnsues.
** [[http://www.fimfiction.net/story/305759/the-clockwork-consequence The Clockwork Consequence]]: Because this story takes place in the "Nightmare Moon wins" timeline shown in ''The Cutie Re-mark Part 2'', Nightmare Moon's most loyal servants include the likes of Rarity, Pinkie Pie, (called "Diane") Rainbow Dash, Applejack, and Trixie. Fluttershy has yet to appear, but by the the way things are going she too is loyal to Nightmare Moon.
** In the Persona crossover ''Fanfic/PersonaEG'' [[spoiler:Fluttershy]] is this of all people. She only [[BitchInSheepsClothing acts shy and friendly around others, but actually keeps her dark side hidden.]] Though glimpses of her true self are hinted at before she is discovered. She became a cyberbully after she was bullied one too many times, but took it too far and [[spoiler:accidentally crippled a teacher once]]. She is eventually revealed as the dark persona user, Eris, and her friends were all shocked to discover her reasons behind doing this. Though CharacterDevelopment eventually turns her just as nice and caring as her canon self, if with a little more snark.
*** Babs Seed and Pinkie's parents count too. Babs was only a bully in the show to avoid being bullied herself, but she is describe here as being worse than [[AlphaBitch Diamond Tiara]], actually hitting people and smoking in the bathroom. Pinkie's parents, despite being old fashioned, accept their strange daughter in the show, but here they are complete jerks who treat her as TheUnFavourite and eventually [[spoiler:disown her entirely.]]
** [[http://www.fimfiction.net/story/159974/pony-age-catalyst Pony Age: Catalyst]] Miss Harshwhinny. In the show she was a JerkWithAHeartOfGold. Here however, she's a RichBitch CorruptPolitician. There's also Iron Will, when you're a Minotaur in a crossover with a game where Minotaurs are enemies, what choice do you have?
** ''FanFic/PrincessTrixieSparkle'' does this with Trixie, who in the show was (not counting when she was under the influences of The Alicorn Amulet) a egotistical JerkAss at worst, and even then outside of that aforementioned incident, she arguably had not done anything morally. In this story, she is a [[ManipulativeBastard manipulative bitch]] who tricks Twilight into letting her steal her identity, frames her and her friends and arguably crosses the MoralEventHorizon [[spoiler: she has Twilight locked in the dungeon and sadistically gloats that she will be trapped in there alone for the rest of her life.]] Granted, [[spoiler: she is being influenced by the ''[[TheManBehindTheMan true]]'' BigBad and does make HeelFaceTurn by the end, but even so, she went above and beyond what she was actually supposed to do and it understandably takes ''awhile'' before anyone is ready to forgive her.]]
** FanFic/RainbowDoubleDashsLunaverse is explicitly an AU with the premise that it was Celestia rather than Princess Luna who went insane. This trope also applies (to a lesser degree) to the Celestiaverse Elements. Lack of the friendships of the others has left them all (but most especially Twilight and Applejack) somewhat... warped.
* Damion, a one-shot character from ''Anime/{{Pokemon}}'', was originally just a {{Jerkass}} becomes a dangerous psychopath in ''FanFic/{{Symbiosis}}''. He is willing to ''kill'' Ash to get revenge on Brock and Misty for reporting his crime.
* Count Mott of ''LightNovel/TheFamiliarOfZero'' is "merely" a [[AristocratsAreEvil decadent noble]] who sexually harasses his servants. In ''Fanfic/{{Unfamiliar}}'', he's an outright psycho who tortures, murders and tortures to death anyone who crosses him.
* Timon and Pumbaa in ''Fanfic/TheLionKingAdventures'', where they're turned into a soul sucking EvilSorcerer and his helper. And Zazu is turned into a ChaoticNeutral backstabbing royal vizier.
* In ''WesternAnimation/TheSimpsons'' AU ''The Fourth Simpson Child'', Lisa goes from a socially isolated smart girl who is somewhat TheUnfavourite to a SmugSnake who is openly jealous of Samantha (her older sister and the title character).
* ''VideoGame/{{Touhou}}'' fanfiction:
** Wriggle is just a run-of-the-mill insect youkai and, while still dangerous, she usually has no malicious intentions against humans and will attack only if provoked. In the fanfic ''[[http://www.touhou-project.com/forest/res/26223.html No Such Thing as Fairy Tales]]'', [[spoiler:Wriggle is a [[Tabletop/ChangelingTheLost fae]], who spirits aways humans and torture and rape them for no other reason because she can.]]
** ''Fanfic/TouhouIbunshu'' does this to almost ''half'' of the cast. Rumia, Mystia, and Remilia are {{Creepy Child}}ren that [[ToServeMan eat people]], Cirno, Wriggle and Hina are sadists that try to kill people for no reason, Sakuya is a SerialKiller and [[spoiler:''succeeds'' in killing the humans]], and Yukari and Mokou both [[spoiler:try to obliterate Gensokyo]]. Strangely, the ones that get some CharacterDevelopment end up being more sympathetic than the originals (most of whom are petty violent jerks), even if they are worse people overall.
** ''Fanfic/ImperfectMetamorphosis'' takes Yuuka Kazami (a powerful and dangerous individual who nonetheless mostly leaves people alone) and turns her into TheDreaded who makes ''every'' character [[OhCrap crap their pants]] whenever she's mentioned, and more than lives up to her reputation by being [[spoiler:a full-blown [[EldritchAbomination Outer God]]]].
* ''Fanfic/DirtySympathy'' does this to several characters: Daryan Cresend ([[spoiler: already DirtyCop]]) into a DomesticAbuser who abuses Klavier and constantly makes death threats. Kristoph Gavin ([[spoiler: an AmoralAttorney and poisoner]]) into a BadBoss who traps Apollo into AllTakeAndNoGive relationship and abuses him because Apollo has no one else to turn to. Machi's portrayal as [[ChildrenAreInnocent innocent child]], albeit an accomplice to drug smuggling, is done away, presenting him as [[FaceOfAnAngelMindOfADemon angelic-looking, distrubed]] smuggler [[spoiler: and he is actually guilty of killing [=LeTouse=]]]. Lamiroir is a cold-blooded MamaBear, who thought nothing of framing someone and threatening someone with death to protect Machi. And the story's leads, Klavier and Apollo become [[VillainProtagonist Villain Protagonists]].
* In ''Fanfic/MegaManDefenderOfTheHumanRace'', Dr. Wily and several Robot Masters are far more villainous than in the show.
* In ''[[Fanfic/ImHereToHelp I'm Here to Help]]'', the senshi of the future, as well as Neo-Queen Serenity, are portrayed as considerably more villainous than their canon counterparts. While we don't see much of them, it's established that they are essentially the BigGood of the future, to the point where they were ''willingly'' asked to rule the now-united Earth. In the fanfiction though, their adoration comes from Neo-Queen Serenity "purifying" all negative emotions out of them, allegedly turning them into placid zombies. While Emerald is something of an UnreliableNarrator due to being insane, one segment told from the point of view of the future Jupiter and Mars has them discuss how they attacked/killed several children who Emerald had help with one of his plans, dismissing the whole thing as the children having made their own choices in the matter. Needless to say, the canon senshi would ''never'' willingly harm children, whether or not they were helping a villain.
* ''Fanfic/SystemRestore'':
** The first and second victims, while acting similarly to how they did in canon ([[spoiler:hoping to kick-start the mutual killing]] and [[spoiler:planning a murder so that Kuzuryuu can gradaute]], respectively), come off as somewhat less sympathetic, since their motives are revealed after their deaths. The second murderer, in particular, seems to have fewer reservations about killing, and even tries to convince [[spoiler:Kuzuryuu]] to go through with killing.
** The second murderer, and the first who's different than canon, is [[spoiler:Sonia Nevermind]], who not only never killed anyone in canon, but was also one of the nicer cast members.
* In the MLP / Franchise/GreenLantern crossover ''FanFic/InBrightestDay'', this treatment gets applied to [[VideoGame/StoryOfTheBlanks Mitta and Ruby]]. In the canon of ''VideoGame/StoryOfTheBlanks'', both were in fact friendly and helpful towards Apple Bloom. However in this story, while Ruby feels constant remorse and guilt for her horrific actions, Mitta seems to be completely villainous and relishing in the pain and suffering of her victims. The reason of this has yet to be explained...
* ''Fanfic/KitsuneNoKenFistOfTheFox'':
** Utakata, Yagura and Gaara are the three most villainous members of the Kyuushingai introduced, with Utakata being an AxCrazy SerialKiller who'll even [[WouldHurtAChild murder children]] in his rampages, Yagura being a cold-blooded gang leader who's infamous for making witnesses set to testify against him "disappear", and Gaara being an aspiring [[TheAggressiveDrugDealer drug kingpin]] who's in an alliance with Yagura. Contrast their canon counterparts from ''Manga/{{Naruto}}'', where Utakata was merely disillusioned after being mistreated due to his jinchuriki status but wasn't otherwise stated to be evil, Yagura only had his bad reputation because he was manipulated into committing bloody actions during his time as the Mizukage, and Gaara is one of Naruto's staunchest friends and allies (though he did start out AxCrazy and only wound up undergoing a HeelFaceTurn following [[DefeatMeansFriendship being defeated in combat by Naruto]]).
** Konan is a member of Akatsuki and determined to kill the Kyuushingai no matter what (in canon, she's also a member of Akatsuki, but there she's a WellIntentionedExtremist who later becomes one of Naruto's supporters).
** The members of the LOVE syndicate's Council of the Dawn, of which Gaara is the leader and Yagura is a member; aside from them, the members include Temari, Kankuro, Matsuri, Chojuro, Darui, Menma, Yura, Sumaru and Kurotsuchi. All of them are criminals, with [[CoDragons Temari and Kankuro]] being Gaara's personal guards, Matsuri being the group's secretary and an assassin in her own right, and the rest being the heads of their own minor syndicates. Contrast that with their canon counterparts: Temari and Kankuro, while they started out as antagonists alongside Gaara, eventually became allies of Konoha; Matsuri, Chojuro, Darui, and Kurotsuchi were allied to Konoha along with their respective villages during the Fourth Great Ninja War; Sumaru started his filler arc being rude to Naruto but eventually became his friend; Menma (the filler character, not the one from the movie) was TheAtoner who'd tried to pull LaserGuidedAmnesia on himself in an effort to leave his bad past behind; and Yura was loyal to the welfare of the Hidden Sand Village [[spoiler:even while he was Sasori's sleeper agent]].
* ''FanFic/RosarioVampireBrightestDarkness'':
** In canon, Tsukune's ghoul form was largely depicted as an instinctive, mindless [[TheBerserker Berserker]]. Here, it's shown as a full-fledged SuperpoweredEvilSide with its own identity and personality.
** Though Hokuto was always an antagonist in the manga, he was more of a WildCard to the extent that he helped Tsukune and Moka stop his own plan. Here, he's a straight-up no-gray-area villain and a blatant StrawNihilist who openly expresses the view that life itself is nothing but a meaningless plague that must be wiped out.
** The fic does away with the sympathetic backstory that Alucard had in canon completely. In the original manga, Alucard was originally supportive of human/monster co-existence, but turned evil after humans invaded the country he founded for exactly that and killed most of his loved ones. Here, Alucard began as an arrogant, overly powerful vampire who decided to simply destroy all life, human and monster alike, out of sheer [[StrawNihilist nihilism]], and eventually devolved into nothing but a mindless beast.
* In ''Fanfic/NecessaryToWin'', Anchovy of Anzio is based off of her manga counterpart, and as such, is a SoreLoser who criticizes Miho's decision to save one of her school's tanks at the cost of winning the tournament. On the other hand, she does go through some CharacterDevelopment and gains respect for Oarai, unlike in the manga.
* ''TNG Recut'', TheAbridgedSeries of ''Series/StarTrekTheNextGeneration'', turns the ''entire crew'' of the ''Enterprise''-D into a bunch of crazed nutcases. Picard takes the cake, though, ultimately leading his crew to strand him on the saucer section and launch it into a planet to get rid of him. And even ''then'' it doesn't work!
* Ms. Maia from TwilightValley. In the sixth WesternAnimation/TheLandBeforeTime movie, she is simply an overprotective mother that tossed out Ducky when ''Ducky'' was the one who invaded her nest in the first place. In the fanfic, Ms. Maia is portrayed as a traitor who attempts to ''murder'' Ducky.
* In ''Disney/{{Frozen}}'', Princess Anna is one of the most kind-hearted, non-malicious Disney characters ever. An AlternateUniverse of songs turn this on its head, likely a result of the memory wipe from the film GoneHorriblyWrong, and turns her into a SerialKiller who [[https://www.youtube.com/watch?v=78g0SyQjU1s kills people and hides their bodies in caves]] (including [[SelfMadeOrphan her parents]] and [[CainAndAbel her sister]]), and [[https://www.youtube.com/watch?v=RlZF0s7Leso happily proclaiming it's useless for her victims to run]] because [[KillEmAll she'll kill them anyway]] and [[ItAmusedMe have fun doing it]].
* ''FanFic/CalvinAtCamp'' does this to [[ComicStrip/{{Peanuts}} Lucy]] and [[WesternAnimation/EdEddNEddy Eddy]].
* The fan film ''Film/{{Grayson}}'' seems to present [[Series/{{Batman}} Chief O'Hara]] as a DirtyCop, aligning himself with Catwoman, yelling at Superman to get Dick Grayson out of the way, and preparing to hit a tied-up Commissioner Gordon.
* [[WesternAnimation/InvaderZim Dib]] in ''FanFic/KingdomCrossovers'' is the replacement of [[Franchise/KingdomHearts Riku]], and thus follows the same path as him.
* ''Videogame/FiveNightsAtFuckboys'': BB was no more dangerous or evil than any of the animatronics in ''Videogame/FiveNightsAtFreddys2'' (which were implied to be {{Tragic Villain}}s more than anything), and he cannot even kill directly. In all three games, however, he's a [[TheChessmaster scheming]] [[ClusterFBomb swearing]] [[MemeticMutation enragement child]] [[AGodAmI with ambitions of godhood]].
* Magolor in ''[[https://www.fanfiction.net/s/10389287/1/Kirby-Right-Back-At-Ya-Season-2 Kirby: Right Back At Ya! Season 2]]''. In [[VideoGame/KirbysReturnToDreamLand Kirby's Return To Dream Land]], he was a kindly alien that gave Kirby advice as he tried to repair his ship. Here, he's effectively an Expy of Customer Service from the original show, being the one who sends King Dedede his new monsters. [[spoiler:It's downplayed compared to most examples, as Magolor was already the BigBad of his own game, but he kept it hidden until the final level, whereas this Magolor is known to be a villain from the first chapter.]]
* The ''Franchise/PowerRangers'' fan film, ''Power/Rangers'' does this to Rocky, having him sell out to and join the Machine Empire. [[spoiler: Bulk and Skull are also imagined as meth users who sold out Jason and killed him for the drug, and Zack is a BloodKnight who joined the Machine Empire just so he could fight again.]]
* ''[[Fanfic/PokemonResetBloodlines Pokémon Reset Bloodlines]]'':
** In [[VideoGame/PokemonRedAndBlue the games]], [[TheMissingno MissingNo]] was a glitch that, while damaging to the game, didn't have any malice. Here, it's the Pokémon equivalent of {{Satan}}, complete with [[DealWithTheDevil Faustian bargains]]. It appears only to mess with Ash's head and tell him [[spoiler:that bad things will happen to his friends from the original timeline]], done as vaguely as possible with the full knowledge Ash can't do anything to realistically stop it. It also mentions that some of these horrible events have already happened, such as [[spoiler:the deaths of Brock's parents]]. It even expresses disappointment that [[spoiler:Norman managed to prevent May from suffering a tragedy]].
** In the ''[[Franchise/{{Pokemon}} Pokémon]]'' [[Anime/{{Pokemon}} anime]], the Sensational Sisters were merely irresponsible and uninterested in their duties as Gym Leaders. While they teased Misty, they were never actually cruel in doing so and genuinely cared about her. At the end of their debut episode, they gave Ash a Cascade Badge out of gratitude for him saving their gym. The fic makes them flat-out corrupt (it's implied they offer trainers money and/or sex in exchange for them throwing matches), keep their Pokémon confined in balls for ''months'' at a time, outright hate Misty ([[ItIsDehumanizing referring to her as "it"]] and kicking her out as soon as they can), and trick/force Ash into a battle they're sure he'll lose so they can keep their gym, not caring that [[spoiler:he'll be barred from taking part in Gym Battles for a year if he does]].
** Paul is an interesting example, because his actual character doesn't change that much. But considering Pokémon have a higher chance of getting seriously injured or even killed this time around, his callous attitude comes off as even worse. At one point, he actually insults Lt. Surge for not wanting to risk his Raichu being horribly maimed by a super-powered Razor Leaf attack.
* The ''Manga/LoveHina'' fics ''FanFic/AnAlternateKeitaroUrashima'' and ''FanFic/ForHisOwnSake'', both written by the same author, make Granny Hina and the Hinata girls ''far'' more malicious and bitchy than they're depicted in canon.
* In the ''Anime/DigimonAdventure02'' fanfic ''FanFic/Digimon02TheStoryWeNeverTold'', there are a couple of characters that are a lot more unpleasant compared to their canon (scratch that, censored) incarnation:
** Mimi and Matt, the former is an AlphaBitch who is willing to run away from all her problems regarding the Digital World, shunning anyone whose name is either a Digidestined or the Digital World. The latter, is a nostalgic man who prefers the old over the new and as a result, hates the new generation of the Digidestined and will not hesitate to denounce them at any opportunity they made a mistake. Fortunately, thanks to ThePowerOfFriendship, they slowly but surely began reverting back to their original canon selves through gradual CharacterDevelopment.
** Cody's BlackAndWhiteInsanity is a lot more prominent in this fic as no matter how much Ken does to redeem himself and atone for his mistakes, he is the only one who still refuse to believe that Ken is actually reformed when everyone else thinks he has atoned enough. It is only when [[spoiler: Ken dies]] that Cody express sufficient enough regret to return back to his former ways.
** In canon, Oikawa is a WoobieDestroyerOfWorlds whose desire to enter the Digital World lets him get possessed by Myotismon and subsequently, any heinous acts done in the anime is blamed to him. But in the fic however, Oikawa is a PsychopathicManchild who is incredibly addicted to his experiences as a [[spoiler: Digidestined]] in the Digital World so much that he is willing to do whatever it takes to achieve such goals. This includes [[spoiler: arranging the death for two of his own Digidestined members as an accident, creating a Digi Armor, fake Digivices & turned Ken into the Digimon Emperor, and kills Ken without a second thought when he feels that he has outlived his usefulness]].
* ''Blog/ThePredespairKids'' manages to make [[Franchise/{{Danganronpa}} Ultimate Despair]] far more insidious, subtle, and cruel than they are in the series. Rather than go full-force with murders and killing sprees, they're biding their time, acting quietly and learning everyone's weaknesses before making their moves. They also have absolutely no problem [[spoiler: [[YouHaveOutlivedYourUsefulness killing their own members whenever they're discovered]].]] And the scariest part about them? ''[[NotBrainwashed None of them are brainwashed]].'' They're doing all of this because they were charmed by Junko or, in [[ManipulativeBastard Maverick]] [[TheSociopath Storm's]] case, ForTheEvulz.
* Throughout ''FanFic/PokeWars'', several Legendary Pokemon get this, including Uxie and especially Ho-Oh, who is a genocidal [[FantasticRacism Fantastic Racist]] and KnightTemplar who wants to KillAllHumans. In the games, the lore surrounding Ho-Oh suggests that it's reclusive but benevolent.
* The ''Fanfic/DayOfTheBarneyTrilogy'' takes Barney and Baby Bop, who are portrayed as sincere and good friends to the kids on ''Series/BarneyAndFriends'', and portrays them as villains who successfully get the world's children to kill any adult they come across, [[spoiler: kill their male Special Friends when they turn thirteen, and take the thirteen year old girls away to fatally [[MedicalRapeAndImpregnate mother]] mutated offspring.]] They're even revealed to be [[Really700YearsOld Really 65 Million Years Old]] and to have been the harbingers of many of the world's evil dictators and catastrophes.
* In ''Fanfic/TheStalkingZukoSeries'', [[Series/AvatarTheLastAirbender Arnook]], a wise and benevolent leader who made the mistake of choosing a jerk like Hahn as his daughter Yue's husband, is portrayed as having a severe case of MoralMyopia, grieving over his daughter while rejoicing when Fire Nation soldiers die. He also doesn't care much for the Southern Water Tribe, as he didn't come to their help when the Fire Nation raided them, and when Hakoda or Sokka try to contradict him, he has the gall to claim that Hakoda's loss of his wife is less painful than his losing Yue.
* ''FanFic/WithThisRing'': [[spoiler: Nabu's actions are not excused as a necessary evil, he is fully portrayed as villainous and needing to be stopped. It's very telling that in the Crime Syndicate MirrorUniverse, where all the heroes are villains, his counterpart Doctor Chaos is a good guy.]]
** Klarion has always been a villain, but he is by far worse in this version. He's actually a Lord of Chaos, an opposite to Doctor Fate, making him easily one of the most powerful magic users in existance.
* Rio in ''FanFic/TheIceQueenCometh''. Her swapping story roles with her brother caused her to be a lot angrier and colder than in canon, though she generally stays in the realm of darker hero than villain.
* ''FanFic/{{Fade}}'': While how heroic he is in canon is up to interpretation, L in this story is a TautologicalTemplar who will go to any lengths to save his life and protect "Justice" from Kira, refusing to acknowledge that this path has led to ''him'' becoming Kira.

* The Franchise/DoctorWhoExpandedUniverse novel ''The Resurrection Casket'' is ''Literature/TreasureIsland [[RecycledInSpace IN SPACE]]!'' Drel [=McCavity=] (the Squire Trelawney character) turns out to be a villain, but not ''quite'' as much of one as Salvo (the John Silver character) who's been "upgraded" to FauxAffablyEvil.
* In the original story of "[[Myth/SaintGeorge Saint George and the Dragon]]" and most reworkings of it, Saint George is the hero, or at worst a WellIntentionedExtremist (usually in versions where the dragon is misunderstood and George assumes it's dangerous). For example, in ''Disney/TheReluctantDragon'', he becomes the title character's friend. Even in retellings where the dragon is SparedByTheAdaptation, George usually convinces it to make a HeelFaceTurn. In the ''Dragon Keepers'' series by Kate Kilmo, Saint George is a VillainWithGoodPublicity who enslaves magical creatures and kills harmless and intelligent dragons for purely selfish reasons (to drink their magical blood) while the princess he saved is an evil witch. The dragon from the original tale tells his own side of the story, in which he was a benevolent sorcerer betrayed and killed by George.
** Later in the series, {{Literature/Beowulf}} gets the same treatment - he became immortal by drinking a dragon's blood and faked his death (in the original story he and the dragon died in a MutualKill). He disguises himself as a BadSanta along with [[AllTrollsAreDifferent trolls]] disguised as ChristmasElves, is CruellaToAnimals, and antagonizes the protagonists by trying to steal [[WouldHurtAChild dragon eggs]].
* ''Literature/MythOMania'' has some in-universe examples: When Zeus rewrote the stories of Myth/ClassicalMythology, he exaggerated monsters' scariness to glorify the heroes. (eg, The Minotaur went from being a vegetarian to eating humans.) Plus, Zeus claimed that Hades kidnapped Persephone, when actually she hitched a ride on his chariot while running away from [[MyBelovedSmother her overprotective mother]].
* The mice from ''Literature/TheHitchhikersGuideToTheGalaxy1'' -- in the radio play, they are fairly amiable, and upon discovering that Arthur is in the ideal position to find the ultimate question, offer to make him "a reasonably rich man" if he does. In the book and subsequent adaptations, however, they are much more sinister, plotting to steal his brain in order to read the question from it.
* FrankensteinsMonster gets this ''a lot''. Literally ''dozens'' of interpretations of the character portray him as an evil fiend, rather than the misunderstood and rejected outcast he was in [[Literature/{{Frankenstein}} the original novel]]. (Mostly due to ArtisticLicense as a plot demands.)
* ''Literature/LandOfOz'':
** While Creator/LFrankBaum didn't elaborate on what makes the Wicked Witch of the East evil (allowing for certain AlternateCharacterInterpretations), Volkov wastes no time in ''Literature/TalesOfTheMagicLand'', and opens the series by portraying her as an OmnicidalManiac.
** Likewise, the Wizard is not necessarily a good guy, and does several reprehensible things, but when Greg Maguire got his hands on Oz for ''Literature/{{Wicked}}'', the Wizard became a power-seeking, first-rate MagnificentBastard who exploits religious factionalism and FantasticRacism to pit his potential enemies against one another, drive Oz into civil war, and start [[ANaziByAnyOtherName genocide of the sentient beasts]] [[spoiler:as a cover for him trying to locate the Grimmerie and obtain absolute power.]]
* ''Literature/AlicesAdventuresInWonderland'':
** The Queen of Hearts is clearly a mean woman and a blustering {{Jerkass}} type, but calling her evil might be stretching the definition a little; though she often calls for people to be beheaded, her husband secretly pardons most of the people she condemns, and the Griffon tells Alice that, "It's all in [the Queen's] fancy, you know. They don't actually execute anyone." Nonetheless, you can be sure in almost any modern story where Alice is portrayed as the protagonist, the Queen of Hearts (often [[CompositeCharacter conflated with]] the Red Queen) will be the villain, and portrayed as ''far'' more evil than Carroll could have ever imagined. Whereas Alice's trial in the book ends with her realizing that the Queen of Hearts' threat against her is empty and dismissing the Queen's court as a pack of playing cards, in [[Disney/AliceInWonderland the 1951 Disney version]], the Queen of Hearts is portrayed as a genuine threat, and the trial ends with Alice running for her life from the Queen and her soldiers before [[AllJustADream waking up]].
** Then there's [[Film/AliceInWonderland2010 Tim Burton's movie]] and [[VideoGame/AmericanMcGeesAlice the popular video game.]] Then Queen of Hearts is [[TheCaligula a mad tyrant]] in the first, and an EldritchAbomination in the second.
** The Jabberwock is often both this ''and'' an AscendedExtra in such works, seeing as the evil beast wasn't even an antagonist for Alice in ''Literature/ThroughTheLookingGlass'', only appearing in the now-famous poem that she read. The poem became so popular that most modern adaptations include the creature as an adversary for Alice and the heroes in general.
* By the end of ''[[Recap/MyLittlePonyFriendshipIsMagicS3E5MagicDuel Magic Duel]]'', it seemed like Trixie made a full HeelFaceTurn [[spoiler:(Which the [[ComicBook/MyLittlePonyFriendshipIsMagicIDW comic]] follows through on)]], which makes her return to an antagonistic role in ''Literature/TwilightSparkleAndTheCrystalHeartSpell'' rather jarring.
* In ''Franchise/SonicTheHedgehog'', Knuckles was misled by [[BigBad Dr. Robotnik]] into fighting Sonic in ''VideoGame/SonicTheHedgehog3'', but quickly made a HeelFaceTurn after realizing his mistake and has generally been a firm ally ever since. In ''Literature/TheSonicTheHedgehogJokeBook'', he seems to be one of Robotnik's full-time minions.
* In ''Literature/{{Noob}}'', the novel version of Donteuil in regards to the webseries one. When that fact that [[spoiler:Fantöm's avatar was illegally enhanced]] get revealed in the webseries, Judge Dead is the one who decides to blame the whole thing on its LockedOutOfTheLoop victim. A couple of webseries scenes give the impression that Donteuil has a MyGodWhatHaveIDone feeling towards the victim in question and it's via Donteuil that the audience eventually finds out that the victim's situation isn't as bad as it first looked. In the novels, Donteuil seems to be the one who decided to pull the "blame the victim" move, while the "situation not as bad as it first looked" reveal comes from a FictionalDocument provided by another character that gets no mention in the webseries.
* In ''WesternAnimation/TheLandBeforeTime'', [[AmbiguouslyEvil it's not clear if Sharptooth can truly be called evil]], and there's a distinct possibility that [[NonMaliciousMonster he's just hungry]]. The novelization, however, portrays him as a narcissistic serial killer who's after the hatchlings out of petty revenge and is implied to kill ForTheEvulz.
* The swan knight in German legends (usually named Theatre/{{Lohengrin}}) is a hero who rescues the girl and marries her. In Robert Southey's ballad ''Rudiger'', he's the villain who sold his soul to the devil and nearly threw his infant son right into hell as part of the deal.

* In the picture book ''The Butterfly Ball'', Sir Maximus Mouse, the cheese tycoon, is simply a workaholic who's too busy to go to the Ball. In Roger Glover's concept album adaptation, he's a borderline-demonic CorruptCorporateExecutive.
* PlayedForLaughs in Music/WithinTemptation's song "Gothic Christmas" where WesternAnimation/RudolphTheRedNosedReindeer becomes an EvilOverlord.
-->Rudolph, he will change his name.
-->'Cause Rudolph just sounds pretty lame.
-->From now on I'll call him Ragnagord
-->The evil reindeeer overlord
-->His nose shall be red no more
-->It will be blacked to the core
-->His eyes will glow an evil glow
-->To guide the chariot through the snow

[[folder:Newspaper Comics]]
* The 1978-1988 ''WinnieThePooh'' comic strip, syndicated by King Features and [[RecursiveAdaptation based on the Disney movies based on the book]], has gained some memetic steam on the Internet for its portrayal of the usually kind-hearted and sugary-sweet Pooh as a complete [[{{Jerkass}} jerkass]], [[ComedicSociopathy usually for the sake of a punchline.]] It's all the more funny (or disturbing) because his face is still fixed in that innocent Disney-merch smile.
--> '''Pooh:''' You take yourself too seriously, Eeyore.
--> '''Eeyore:''' You mean I should laugh at myself, Pooh?
--> '''Pooh:''' Why not? Everyone else does.

--> '''Pooh:''' How are you, Piglet?
--> '''Piglet:''' Well, actually, Pooh…I didn't sleep too well last night and…
--> '''Pooh:''' Please, Piglet! I was just being nice! I don't have time for all that today!

* Aside from a fight when she premiered in one issue of the ComicBook, the Black Widow has never been a Franchise/SpiderMan villain. Yet Creator/{{Gottlieb}}'s ''Pinball/TheAmazingSpiderMan'' pinball has her on the backglass along with Spidey's other rogues, such as the Vulture and the Green Goblin.
* In Creator/ZenStudios' ''[[VideoGame/SpiderManZenStudios Spider-Man]]'' pinball, J. Jonah Jameson is elevated from an annoying nuisance (and often portrayed with [[JerkWithAHeartOfGold some redeeming qualities]]) to one of four villains for Spider-Man to fight.

[[folder:Tabletop Games]]
* In ''TabletopGame/{{Pathfinder}}'', the Tarrasque is upgraded from the highly destructive but NonMaliciousMonster it is in ''TabletopGame/DungeonsAndDragons'' to a ChaoticEvil agent of the god Rovagug the Worldbreaker.

* ''Theatre/{{Wicked}}'' the musical is still an example, but is more sympathetic to [[Literature/TheWonderfulWizardOfOz The Wizard]] than [[Literature/{{Wicked}} the book version]] above, portraying him as a sort of a WellIntentionedExtremist who is puppeteered by Madame Morrible and generally seems to want the best for Oz, as long as he remains its leader.
* This happens to several characters in ''Theatre/LoveNeverDies'', the sequel to ''Theatre/ThePhantomOfTheOpera''. The trope applies in two ways, both because characters from the first musical undergo villain transformations and because in ''Literature/ThePhantomOfManhattan'' (the Frederick Forsyth novel that was the result of early work on what became this show) contains no such transformation, instead having the villain be a completely new character who didn't make it to the stage. Madame Giry is more-or-less the main antagonist, and only helps the Phantom for the reward it earns her. Meg gradually loses her sanity while trying to [[spoiler:start a relationship with the Phantom]], culminating in her [[spoiler:kidnapping and attempting to drown Gustave, then ultimately shooting Christine]]. Meanwhile, more adaptational {{Jerkass}} than villainy, but Raoul is now a cranky alcoholic whose gambling has put the family in a load of debt, and no longer feels the love for Christine that he once did.
* In ''Wonderland: Alice's New Musical Adventure'', the Mad Hatter becomes [[GenderFlip female]] and the play's main antagonist, with the March Hare as her [[TheDragon Dragon]]. In the book, he's [[TheMadHatter scatterbrained]], but not particularly malicious about it.
* Brecht's ''Theatre/TheThreePennyOpera'' makes Macheath considerably more unpleasant than he was in ''Theatre/TheBeggarsOpera''. In the original play, Macheath is a gallant [[TheHighwayman highwayman]] who doesn't kill except in self-defense, and while [[TheCasanova utterly incapable of remaining faithful to one woman]], is an overall nice guy. In contrast, Macheath in Brecht's play is a mass murderer and rapist and only rarely pleasant. An additional change is that lines from the original play given to Peachum involving plans to [[YouHaveOutlivedYourUsefulness sell out criminal associates to the authorities with full knowledge they will be hanged]] is given to Macheath in ''Theatre/TheThreePennyOpera'', changing Macheath from an example of HonorAmongThieves to one of NoHonorAmongThieves.
* In ''Theatre/TheGoldenTicket'', an opera adaptation of ''Literature/CharlieAndTheChocolateFactory'', SpoiledBrat Veruca Salt agrees to a deal with a TV reporter to secretly film and photograph the titular, top-secret factory during the Golden Ticket tour -- which makes her and her dad, who goes along with the plan, spies. As well, she's ''much'' nastier in her selfishness than in other versions, and specifically contrasted with poor-but-good Charlie Bucket throughout. With this in mind, while the novel and all other adaptations have them the third group to be eliminated from the tour, here they're the fourth and last to go.
* In ''Theatre/TheRingOfTheNibelung'', Hagen goes through this. He is largely a CompositeCharacter of Hagen from Literature/TheSagaOfTheVolsungs and ''Literature/{{Nibelungenlied}}''. However in the Volsung Saga he is Gunther's heroic brother and though a more villainous figure in the Nibelungenlied, murdering Siegfried, there he is acting out of loyalty to Gunther. In the Ring Cycle Hagen is the son of the main villain Alberich and murders Siegfried and [[CainAndAbel Gunther]] for the RingOfPower.
* ''The Boyg'' was originally a troll/monstrous abomination from the stories of Creator/AsbjornsenAndMoe. The original Per Gynt managed to finish it by shooting it point blank between the eyes. In the play ''Theatre/PeerGynt'', written by Creator/HenrikIbsen, the Boyg is an almost invincible EldritchAbomination that does a MindRape on the titular character, and who is the driving force for Peer´s demise throughout the play, actually the real BigBad (set up against the true BigGood: Solveig).

[[folder:Visual Novels]]
* In ''VisualNovel/AstoriaFatesKiss'', Hercules - who certainly has problems but is generally considered a hero in Myth/ClassicalMythology - is the main antagonist of Hydra's route, taking advantage of his status as the son of Zeus to use H.E.R.A. resources while acting outside of their chain of command. He turns out to have assaulted several people, including his own ex-wife, in order to steal the Auras that are the sources of their power for his own use.

[[folder:Web Comics]]
* After ''Webcomic/{{minus}}'' ended, the author created some gag strips that parody scenes from the original webcomic, and whhich are not in continuity. If they are interpreted as a CompressedAdaptation of the original work, then minus gets hit with this trope, big time. Whereas in the original she is merely a TricksterArchetype who only does bad things because [[MikeNelsonDestroyerOfWorlds she doesn't understand the consequences of her actions]] and frequently [[PetTheDog softens her antics to make them not as bad]], in the [[http://www.kiwisbybeat.com/minuse2.html extras]] she is a cruel and vindictive psychopath who takes out [[FamilyUnfriendlyDeath horrifying revenge]] on people for [[DisproportionateRetribution excruciatingly minor slights]], behavior which the minus from the main webcomic would never do. In the strip that has been linked, she actually turns one of her classmates into a chalk drawing and smudges her, even after the classmate apologized.
** When it comes to other characters, the extras actually contain a spectacular {{Inversion}}. [[http://www.kiwisbybeat.com/minus106.html One strip]] features a man who stuffs minus in a briefcase after [[TooSmartForStrangers luring her in with promise of sidewalk chalk]], and who would certainly have tried to abduct her if he wasn't stopped. His counterpart in [[http://www.kiwisbybeat.com/mnus9.html the extras]], on the other hand, is an innocent bystander who doesn't do anything to deserve being antagonized by the villainized minus.
* ''Webcomic/SonicTheComicOnline'' does this with many games characters. Shadow, Rouge, the Babylon Rogues, Bean, Silver... even Cream the Rabbit! Blaze is immune to this, being almost identical to her game counterpart.
* ''Webcomic/KnightsOfBuenaVista'' does this to the bishop in ''{{Disney/Frozen}}''. In the movie, he just officiates Elsa's coronation. In this comic, he's [[HypnotizeThePrincess using magic to hypnotize Elsa]]. [[spoiler:This is then subverted when it's revealed to be a magic doppelganger impersonating the real bishop.]]
* ''Webcomic/DarthsAndDroids'' does this to [[spoiler: Han Solo, who shortly before being frozen in carbo... er, alcohol, admits he's been feeding information the the Empire for months. Jim was really impressed with how Annie roleplayed Anakin's StartOfDarkness and wanted to do the same.]] Similarly, this also applies to [[spoiler: Padme Amidala, due to the fact that ''she'''s Darth Vader in this version.]]
* In ''Webcomic/{{Roomies}}'', Mary started out being intended as a Voice of Reason, and gradually became portrayed as more hypocritical as the author found himself questioning his fundamentalist upbringing and, therefore, Mary's opinions on things. In ''Webcomic/DumbingOfAge'', she's straight-up one of the least sympathetic characters from the get-go, representing everything Willis dislikes about his background. Similarly Joyce's mom in the Webcomic/{{Walkyverse}} went from "background mother character" to "background mother character [[ParentalSexualitySquick who has lots of sex with her husband]]" to "[[IWantGrandkids deeply obsessed with having grandkids]]", while her Dumbiverse counterpart is mostly characterised by religious intolerance.

[[folder:Web Original]]
* [[http://thatguywiththeglasses.com/blogs/write/entry/top-five-miscast-disney-villains This page]] lists five well-known characters who were reimagined into villains through Disney movies in this way.
* Creator/FrancisEDec insisted in his letters that his brother was a "deadly felon-murderer and secret assassin-spy agent against me for this Gangster Government". Seeing how Dec saw the entire universe ThroughTheEyesOfMadness, we can safely guess that this wasn't the case.
* ''WebVideo/DragonBallZAbridged'':
** Mr. Popo. In the original show, he was a kind, peaceful man who helped the protagonists. In this version, he is a rude, sadistic and intimidating bully who all the main characters fear. He puts his students through hellish training for the fun of breaking them, is implied to be a rapist, has a magic carpet fueled by souls (suggesting he kills people for their souls), plots to destroy the world with Shenron, and Kami states that the last time Mr. Popo kicked him off the lookout, when he came back "I found five corpses. He laughed when I said five". [[spoiler:Ever since Kami's fusion with Piccolo he seems to be adding a more affable nature to his interactions with the cast, though it's clear he can switch back whenever he wants]].
** Guru. Unlike the kind grandfather-like figure he was in the actual series, here he caused a huge drought that nearly wiped out the Namekian race, blamed the Albino Namekians for it, and ordered their genocide. He also orders Nail to murder Krillin, and sends Nail to fight a battle with Freeza knowing he stands no chance. When the heroes summon the dragon, Guru dies on purpose and ruins everything just to be a dick. Guru also laughs when he hears that Vegeta slaughtered a Namekian village, [[spoiler:and is finally killed brutally by the Namekians rather than dying of old age by being EatenAlive after he confesses his sins about the drought and then realizing [[DidntThinkThisThrough he wasn't dying quite yet again]]]]. In the ''Lord Slug'' movie, it was revealed that he was Slug's evil half, and that he suggested to Slug that he attack Earth in the first place, telling him that their defenses suck.
** Doctor Briefs' descent into this started with the occasional sexist remark. He's since turned out to be an amoral MadScientist with a laundry list of prejudices who considered giving his own daughter an ExplosiveLeash. Oh, and the reason his wife never seems to age? [[spoiler: Cloning. He grows them in his basement.]] He's still better off than Mr. Popo and Guru though since he performs nowhere near as many KickTheDog moments as them, helps the cast more often than hinders them, and most of his villainy is in his remarks rather than actions.
** Downplayed example with Android 16. While he remains the GentleGiant FriendToAllLivingThings he was in canon, he was also monomaniacally focused on killing Goku much moreso than in ''DBZ''. It wasn't until 17 suggested that he get a hobby that his character started softening, but his default response to any given situation is still "Kill Goku".
** Bardock is a strange case in that Team Four Star didn't change his personality, but rather they kept it consistent. TFS has said that they liked Bardock as the {{Jerkass}} VillainProtagonist he was in ''Father of Goku'' and openly expressed distaste for his gradually softening into into a gruff AntiHero in ''Episode of Bardock'', feeling that it took away the things that made him stand out among the ''DBZ'' cast. As a result, in their adaptation of ''Episode of Bardock'' he retains his original personality, fighting Chilled's minions because of his own vendetta against Freeza rather than for any kind of noble or high-minded ideal.
** In the original ''[[Anime/DragonBallZTheHistoryOfTrunks History Of Trunks]]'' special, Future Gohan clearly loves his parents and doesn't seem to hold a grudge towards either of them despite their treatment of him but in the abridged version, he outright hates his parents and cares very little of either Goku or Chi Chi to the point that he didn't even care that the former had died. Case in point, in canon Gohan wears Goku's clothes because it reminds him of his father and wants to be as strong as him to fight off the androids while in abridged he only wears it because it's the only thing that Goku left him with. As for Chi-Chi, in canon she is worried about Gohan constantly fighting the androids implying that they at least are still in decent terms which contrasts the abridged where Chi-Chi has fallen into depression because Gohan abandoned her meaning that she could never be the grandmother she wanted in his whole life.
* In ''WebAnimation/{{RWBY}}'', Weiss Schnee started out as a total {{Jerkass}} and a {{Spoiled Brat}}, with some [[FantasticRacism racist attitudes towards faunas]]. However, [[AbusiveParents she had]] [[ParentalNeglect a number of]] {{Jerk Justifications}} for her poor attitude and a solid Freudian excuse for her racism. Weiss eventually became a nicer and more selfless person over time, along with mostly overcoming her prejudices against faunus. In ''WebVideo/RWBYTheAbridgedSeries'', Weiss Schnee is [[JerkWithAHeartOfJerk a much worse person]]. [[EstablishingCharacterMoment She’s introduced fantasizing about performing an ethnic cleansing on Beacon Academy]] [[BadBoss while physically assaulting one of her workers because he politely asked if she’d stop making him sleep in the freezer]]. [[MeanBoss She outright admits that she doesn’t want her workers to be happy]]. Weiss is stated to kidnap people and [[DeadlyEuphemism repurpose]] them, heavily implying she either sends them into forced labor camps or the slave trade. [[FantasticRacism Weiss enjoys killing faunas]] and [[InsaneTrollLogic believes the fact they don’t have civil rights is a justifiable reason to oppress and mistreat them.]] [[ArsonMurderAndJaywalking She also has a drug problem]] [[ItMakesSenseInContext from sniffing too much dust to hide a German accent.]]
* ''WebVideo/DanganronpaAbridgedThing'' does this to the first murderer. In canon, the crime was committed in what was arguably self-defense, although it's pointed out that the killer technically went out of his way to get to and finish off the victim. In the abridged series, the murderer accepted the victim's invitation, hoping to "get some," and killed her when she called him a "weenie."
* In ''Film/{{Downfall}}'' [[http://en.wikipedia.org/wiki/Hermann_Fegelein Hermann Fegelein]] is simply Heinrich Himmler's Number Two man who Hitler killed for trying to leave the Bunker and flee Berlin. In WebVideo/HitlerRants, however, he's portrayed as a malicious TricksterArchetype and ScrewySquirrel whose "antics" constantly bamboozle [[ButtMonkey Hitler]] at the drop of a hat, making Fegelein the BigBad. Granted, this stuff is PokeThePoodle compared to the [[http://en.wikipedia.org/wiki/Pripyat_swamps_(punitive_operation) real-life Fegelein's "antics" in Byelorussia]].
* [[PlayedForLaughs Hilariously]], the LighterAndSofter version of the game ''TabletopGame/{{Warhammer 40000}}'', [[http://1d4chan.org/wiki/Brighthammer_40,000_%282nd_edition%29 Brighthammer 40000]], does this to the Tau Empire. To explain, ''Warhammer 40000'' is an [[RefugeInAudacity extremely]] [[CrapsackWorld grimdark]] setting, with a number of genocidal, xenocidal and one or two [[OmnicidalManiac omnicidal]] factions locked in a ForeverWar. The sole exception is the Tau, who are [[BlackAndGrayMorality still bad in a sense but one of the more sane, if totally unsympathetic, factions]]. For '''''Bright'''''''hammer 40000'', every faction ''except'' the Tau have been made more sympathetic, while the sinister aspects of the Tau have been played UpToEleven, along with some new ones added. This has the effect of turning the Tau into the setting's BigBad. Water Caste Tau are all conniving schemers and cheating merchants, Air Caste Tau are all cowards who launch unprovoked bombing runs and orbital strikes on defenceless worlds, Fire Caste Tau are all violent brutes who bully other Tau and use prisoners of war for target practice (when they bother to take prisoners at all), and the Ethereals run the empire as this horrible 1984-esque society and often use mind-control to order Tau to kill themselves, sometimes for fun. Only the Earth Caste escape this treatment, being poor schmucks who are abused, exploited and left to die when they're no longer useful.
* Since the fan who is recalling ''Manga/JojosBizarreAdventureStardustCrusaders'' replaced characters from the series with characters from other works in ''WebVideo/VaguelyRecallingJoJo'', this trope was bound to happen. He replaced Ebony Devil with [[Manga/{{Negima}} Negi Springfield]], Nena with [[VideoGame/GuiltyGear Bridget]], Steely Dan with [[Manga/ThePrinceOfTennis Atobe Keigo]], ZZ with [[VideoGame/FZero Captain Falcon]] and High Priestess with [[WesternAnimation/ThePowerpuffGirls Blossom]].
* The Midwestern Brotherhood of Steel are just downright fascist in one of the worlds from ''Roleplay/WeAreOurAvatars'', they even tortured an Enclave soldier even though he's a PunchClockVillain.
* ''WebAnimation/ProstituteMickey'' does this to a few Disney characters, mainly to establish exactly how crappy Mickey's life is in the series.
** Mickey's best friends Goofy and Donald have become a drug addict prone to committing robberies and a legless cripple prone to giving Mickey violent threats respectively.
** The ChristmasEpisode features a character named Ebenezer, who is essentially the series' version of Scrooge [=McDuck=]. While most incarnations of Scrooge have been greedy and cheap at worst, Ebenezer was a pedophile who paid children to let him urinate on them, and one of the children he did this to was a younger Mickey.
* Series/{{Teletubbies}} in Machinima/Supermarioglitchy4sSuperMario64Bloopers.
* The various "[[YouAreGrounded Grounded]]" videos made through Website/GoAnimate tends to make "baby show" characters, such as ''WesternAnimation/{{Caillou}}'' and ''WesternAnimation/DoraTheExplorer'' from well-adjusted and lovable characters to spoiled brats who enjoy causing all sorts of destruction and mayhem. It doesn't help that, at times, their parents are just as bad.
* In the Goodtimes Entertainment version of ''Beauty and the Beast'', Beauty's father is a kind and loving man. {{Phelous}}, however, makes him a selfish, greedy, and manipulative BitchInSheepsClothing who mistreats his children.
* In ''VideoGame/PokemonRedAndBlue'', [[TheMissingno Missingno.]] is a glitch that doesn't make much effort to impede the player, is often encountered by accident, is laughably pathetic in battle, and [[GoodBadBugs is outright beneficial in duplicating items]]. However, in ''WebVideo/AtopTheFourthWall'' [[spoiler:where it is first known as [[BigBad the Entity]]]], it's a nigh-invincible EldritchAbomination that desires to absorb all of existence into itself, [[AdaptationalBadass and its power is great enough to reduce worlds to nothing]].
