* In the ''ComicBook/TheMightyThor'' comics, ComicBook/{{Loki}} is generally depicted as an evil god (though some individual writers have made him more of an AntiVillain), but in the original Norse mythology he's a much more ambiguous figure, usually taking the role of TheTrickster.
* Played with in the case of the Greek gods and goddesses in ''Franchise/WonderWoman''. A number of them started out as LighterAndSofter than they were in GreekMythology. However, Ares, the God of War, is portrayed as so dangerous and TooPowerfulToLive that Wonder Woman has to actually ''kill'' him in at least one adaptation. Ares in the Greek myths, although TheBerserker and ironically a bit of a DirtyCoward, [[HiddenHeartOfGold looked after his kids]] and was worshipped like the other gods. However, the more recent Wonder Woman stories have taken to portraying the pantheon as somewhere closer to what they were like in mythology.
** Heracles in the modern adaptation is portrayed as a villain who raped Hippolyta (instead of just seducing her). He becomes TheAtoner, however.
** Ironically, in the {{New 52}} Wonder Woman series, Ares (only referred to as "War") is one of the few Olympians who isn't somewhat villainous. The most villainous of the Olympians is Apollo, one of the most noble Olympian gods in the original mythology.
* In ''UltimateFantasticFour'', [[spoiler:Reed Richards]], a hero in the original [[ComicBook/FantasticFour comics]], becomes a major villain.
** This also happens to the [[ComicBook/TheIncredibleHulk the Hulk]], Hank Pym, several X-Men, and [[spoiler: the Black Widow]], who become more villainous characters in the UltimateUniverse than their original incarnations were.
** Also, [=Jean DeWolf=], a heroic female police officer in the original ''SpiderMan'' comics, was made a corrupt double-agent working for the Kingpin in the UltimateUniverse.
* John Rockerduck is portrayed as a CorruptCorporateExecutive in several stories but he was by no means this or any other kind of villain in the only story [[CarlBarks his creator]] used him in.
* Chaos in ''ComicBook/SonicTheComic'', who is depicted as a transformed and already villainous Drakon Prosecutor with no sympathetic backstory or clear motivation. In ''VideoGame/SonicAdventure'', he is a mutated Chao who was previously peaceful, only turning violent when all of his Chao friends were massacred by the Knuckles Tribe, under the leadership of Chief Pachacamac. Tikal the Echidna, who Chaos tortures in the comic, was his friend in the game, and the two leave in peace after Chaos is calmed down.
** Robotnik himself, while still maintaining some of his comical pathos from the games and other incarnations, is far more evil and void of redeeming aspects, gaining a similar dictator role as his ''WesternAnimation/SonicSatam'' and ''WesternAnimation/SonicUnderground Underground'' counterpart (see below), then he becomes even worse than his game and other incarnations by [[OmnicidalManiac trying to destroy Mobius outright]].
** Even Sonic himself to an extent, who is a much bigger {{Jerkass}}. Also Super Sonic is a psychopath.
* The {{New 52}} version of [[Franchise/{{Batman}} Mr. Freeze]], who has been revised to be less of an AntiVillain. He's still out to cure his frozen wife Nora - but this is a lie. Nora was preserved long before Freeze was even born, he's just deluded himself into believing they're married as part of his obsession with cold.
** The antivillain version of Freeze was based off of WesternAnimation/BatmanTheAnimatedSeries. The original Freeze, from the Silver Age, lacked any humanistic qualities, being an unrepentant villain who uses a cold theme.
** In ''{{Aquaman}}'', [[spoiler: Vulko has undergone a FaceHeelTurn, due to bitter exile]].
** ComicBook/TheCreeper, formerly a GoodCounterpart to SelfDemonstrating/TheJoker as well as an alter ego of Jack Ryder, was brought back in ''{{Katana}}'' as a demonic villain who seems to want to ''haunt'' Ryder.
** In the original ''Franchise/{{Batman}}'' comics, Francine Langstrom was the long-suffering wife of Kirk Langstrom/Man-Bat, whose occasional bouts of being She-Bat were either against her will or out of a desire to keep her family together, and she generally had more control than Kirk did. The New 52 version [[spoiler: is an industrial spy who only married Kirk to steal the Man-Bat formula, and who based her own version of the serum on a ''vampire'' bat, making her much more vicious than Kirk is.]].
** In the New 52 ''Comicbook/TeenTitans'', [[spoiler: Raven is a willing servant of her father, the demon Trigon, and is using the Titans as part of a thus-far undisclosed plan; Superboy is a living weapon who doesn't really "get" morality (and has now been replaced by a full-blown murderous psychopath); Cassie/Wonder Girl is a thrill-seeking cat burglar; and Bart/Kid Flash is a former terrorist leader (albeit against a really horrible-seeming regime). Tim/Red Robin is a bit of a jerk as well.]]
* [[spoiler: Geppetto and Goldilocks]] in {{Fables}}. In their respective stories, [[spoiler:Geppetto]] is a benevolent, fatherly figure while [[spoiler:Goldilocks]] is nothing more than a harmless, if annoying, intruder. In the comics, on the other hand:
** [[spoiler: Gepetto is "The Other", the vicious tyrant who has crushed thousands of fantasy worlds and murdered billions, all in the name of peace.]]
** [[spoiler: Goldilocks is a vicious rabble-rousing anarchist who stirs up revolution just for the fun of seeing people fighting.]]
** Hansel, one of the protagonists of [[Literature/HanselAndGretel his fairy tale]], grows up to become a sadistic witch-hunter and [[FantasticRacism Fantastic Racist]] who, among other heinous acts, murders his own sister.
* IDWPublishing has done this with quite a few characters in their take on the Franchise/TransformersGeneration1 mythos.
** ''ComicBook/TransformersAllHailMegatron'': Downplays this with a look into Prowl's character. While Prowl is normally a "good" if somewhat stuck-up bot of logic and intelligence, here he's more of a WellIntentionedExtremist, doing numerous unethical things, like messing with minds and destroying evidence of Autobot war-crimes, all to preserve their faction. He's also willing to deflect suspicion, blackmail, and conspire to make WMD's all for the sake of the Autobot cause. Prowl did suffer from a bit of DependingOnTheWriter though, beyond the already said where he was also written as a selfless Good guy in ComicBook/TheTransformersIDW while on the same time being a schemer in ComicBook/TransformersLastStandOfTheWreckers. His character eventually went back to "unethical but for the greater good" with ComicBook/TransformersRobotsInDisguise.
** [[spoiler: Spike Witwicky]] in ''[[ComicBook/TheTransformersIDW The Transformers]]'' is nothing like his G1 cartoon predecessor. While in the G1 cartoon, he is undoubtedly a good guy and aids the Autobots, in the comic, he is an utter jerk to many, and has a more sinister, hidden goal for aiding the Autobots.
** ''ComicBook/TransformersLastStandOfTheWreckers'': Overlord's appearance in [[TransformersSuperGodMasterforce Masterforce]] had him as a ProudWarriorRaceGuy, and honorable enough to turn on his evil boss and help the heroes. His appearance in the [[TransformersClassics Classics community]] had him as a straight up villain, and Decepticon conqueror, but that pales in comparison to his appearance in LSTOTW (and later MTMTE), where he is one of the most depraved Decepticons ''ever'', murdering populations of creatures, pitting Autobot prisoners against each other and his own troops for his amusement, and then executing all of them so they can't be rescued.
** ''ComicBook/TransformersMoreThanMeetsTheEye'': Has Star Saber, once the heroic leader of the Autobots in the [[TransformersVictory Victory]] Cartoon, his IDW portrayal has him as a [[TheFundamentalist religious fanatic]] who once attempted an atheist Holocaust. He works for the BigBad to bring about the end of the "impure" transformers, including [[spoiler: his GoodCounterpart, Dai Atlas]], whom he had religious disagreements with.
** IDW's version of Rattrap, particularly in ''[[ComicBook/TransformersWindblade Windblade]]'', but also present in [[TransformersRobotsinDisguise Robots in Disguise]]. His ''WesternAnimation/BeastWars'' counterpart was a JerkWithAHeartOfGold who could be counted on to do the right thing, albeit complaining all the time. IDW's version? A selfish, backstabbing, amoral creep who plays TheStarscream to Starscream himself.
* Baron Karza in the Marvel ''Franchise/{{Micronauts}}'' comic books is the BigBad of the "Homeworld" sector of Microverse. The toy line gave little to no characterization of the various figures. In the toyline, he was described as the rival to Force Commander but he was also one of a number of assorted Magno figures of a similar theme. There were also other European release only characters such as Green Baron and King Atlas. All of these characters were lesser nobles under a figure named Red Falcon who was the right hand of an Emperor Megas. In the toyline, Karza seemed to be evil by default because of [[GoodColorsEvilColors color coding]] and because Karza bore a passing resemblance to [[DarthVaderClone another armored villain from]] ''[[Franchise/StarWars a then recent very popular]] [[Film/ANewHope space fantasy movie.]]'' But we don't know for sure if he was the worst of the worst, especially since Megas does an even better job at the [[DarthVaderClone passing resemblance]].
* Wonder Dog in ''WesternAnimation/{{Superfriends}}'' is a cute, ''Franchise/ScoobyDoo'' like mascot. Wonder Dog in the DC comics is a hellhound who disguised himself as a normal dog, ''killed'' Marvin, and paralyzed Wendy. He ended up getting killed by the Teen Titans in the end.
** In his cameo in the ''WesternAnimation/JusticeLeague'' episode "Ultimatum" he's portrayed similarly as a beast.
* IDW's ''Star Trek: Countdown To Darkness'', set in the [[AlternateTimeline Alternate Reality]] between ''Film/StarTrek'' (2009) and ''Film/StarTrekIntoDarkness'' features the new timeline's version of the original ''Enterprise's'' first captain in the prime reality, [[http://en.memory-alpha.org/wiki/Robert_April Robert April]]. [[spoiler: He FaceHeelTurn[=s=] into a rogue AntiVillain, hijacking the new ''Enterprise'' in order to save an alien species from extinction.]]
* ''Marvel Noir'' has some cases, most notably the XMen, who, in this timeline, aren't mutants, but sociopaths– and [[spoiler: Jean Grey killed Rogue]].
** In ''{{Wolverine}} Noir'', the BigBad is [[spoiler: Rose, from Wolvie's mini ''Origin'']].
