->''"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 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 to [[TheScrappy 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 then 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]]
* Fandom has a specific term for taking a character that is good (or neutral) and downgrading them to villain: RonTheDeathEater
* ''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.
* ''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 UltimateEvil, 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.]]
* 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]] 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), they come off as somewhat less sympathetic, since their motives are revealed after their deaths.
** 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 / GreenLantern crossover ''FanFic/InBrightestDay'' while [[StoryOfTheBlanks Mitta and Ruby]] 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).
* ''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.
* 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.
* ''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."
* ''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!
* ''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".
** Guru. Unlike the kind grandfather-like figure he was in the actual series, here he caused a huge drought that nearly whipped 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. 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.]]
* Ms. Maia from TwilightValley. In the sixth 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 [[{{Peanuts}} Lucy]] and [[EdEddNEddy Eddy]].
* In the [[{{WebAnimation/RWBY}} original show]], 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 [[TragicBigot racist behavior towards faunas]]. [[DefrostingIceQueen Weiss eventually became a nicer]] and [[TookALevelInKindness more selfless person]] over time, along with mostly [[CharacterDevelopment overcoming her prejudices against faunus]]. In ''WebAnimation/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 from sniffing too much dust to hide a German accent.]]
* The fan film ''Film/{{Grayson}}'' seems to present [[Series/{{Batman}} Chief O'Hara]] as a CorruptCop, 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'' parody 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.]]

* 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. 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 HeelFaceTurn. In the ''Dragon Keepers'' series by Kate Kilmo, Saint George is a VillainWithGoodPublicity who enslaves magical creatures and drinks dragons' 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/AliceInWonderland 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 victims 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 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.

* 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.

* ''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.

* In ''VisualNovel/LabyrinthsOfAstoria'', 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.

* 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/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.]]

* [[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.
* 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 ''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/JoJosBizarreAdventure'' 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/PowerpuffGirls 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.
