* In the ''ComicBook/TheMightyThor'' comics, SelfDemonstrating/{{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.
** He himself noticed this and killed himself in the ''ComicBook/{{Siege}}'' to change. His success is... ambiguous, but he managed to ''not'' go back to straight up villainy for years (as of 2015 he still didn't, instead literally waging war against himself).
* 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 Myth/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 ComicBook/{{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 the ComicBook/UltimateMarvel Universe:
** In ''ComicBook/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]], [[ComicBook/AntMan Hank Pym]], several Franchise/XMen, and [[spoiler: the Comicbook/BlackWidow]], who become more villainous characters in the ComicBook/UltimateMarvel Universe than their original incarnations were.
*** [[spoiler: Black Widow is basically a reversal of her original counterpart, who started off as an evil Russian spy before reforming and becoming an Avenger. Here, she's introduced as a seemingly heroic defender of justice, but turns out to be a murderous traitor acting as TheMole for the Liberators]].
** Also,Jean [=DeWolf=], a heroic female police officer in the original ''Franchise/SpiderMan'' comics, was made a corrupt double-agent working for the Kingpin in ''ComicBook/UltimateSpiderMan''. ComicBook/IronFist also worked for the Kingpin.
** SelfDemonstrating/{{Magneto}} went from a morally complex, ambiguous figure to an outright genocidal mutant supremacist, who [[AbusiveParents abuses his son physically and emotionally]] and is a blatantly hinted cannibal.
** More like "Adaptational {{Jerkass}}", but outside of [[ComicBook/UltimateSpiderMan Peter Parker]], even most of the characters who are still heroes got this, as they're either jackasses, psychotic, or (more often) both. ComicBook/CaptainAmerica is a good example, as he's noticeable more rude and bigoted than his "classic" counterpart, with lots of DeliberateValuesDissonance.
* 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 - in the games, he was an alternate form of Sonic as opposed to a full-blown SplitPersonality ([[SuperpoweredEvilSide and a nasty one at that]]).
* The ComicBook/{{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.
** Of course, the antivillain version of Freeze [[CanonImmigrant in the first place was based off of his alternate portrayal]] in WesternAnimation/BatmanTheAnimatedSeries. The original Freeze, from the Silver Age, lacked any such humanizing qualities, being an unrepentant villain who uses a cold theme.
** In ''ComicBook/{{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 ''ComicBook/{{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 was later 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.]]
** In the original ''Comicbook/NewGods'', the good gods of New Genesis were the creative free-will of chaos, and the evil gods of Apokolips were the stifling controlling forces of order. In the New 52 version (as seen in ''Infinity Man and the Forever People'' and ''Comicbook/GreenLantern: Godhead'') they ''both'' represent order and control, with Highfather as a WellIntentionedExtremist, who may be just as much a threat to humanity as Darkseid.
* [[spoiler: Geppetto and Goldilocks]] in ''ComicBook/{{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 Adversary", 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.
* Creator/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. He does numerous unethical things, like messing with minds and destroying evidence of Autobot war-crimes, all to preserve the dignity of their faction. He's also willing to deflect suspicion, blackmail, and conspire to make [=WMDs=] all for the sake of the Autobot cause. Prowl did suffer from a bit of DependingOnTheWriter though, as he was also written as a selfless good guy in ComicBook/TheTransformersIDW while at the same time being a schemer in ComicBook/TransformersLastStandOfTheWreckers. He eventually reverted to an UnscrupulousHero 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.
** Overlord in [[Anime/TransformersSuperGodMasterforce Masterforce]] had him as a ProudWarriorRaceGuy, and honorable enough to turn on his evil boss and help the heroes. His appearance in the [[Franchise/TransformersClassics Classics community]] had him as a straight up villain, and Decepticon conqueror. All of them pale in comparison to his appearance in ''ComicBook/TransformersLastStandOfTheWreckers'' (and later ''More Than Meets The Eye''), where he is the BigBad, and one of the most depraved Decepticons ever. He murders populations of creatures, pits Autobot prisoners against each other and his own troops for his amusement, and then executes all of them so they can't be rescued.
** ''ComicBook/TransformersMoreThanMeetsTheEye'' does this to Star Saber. In the [[Anime/TransformersVictory Victory]] cartoon, he is a squeaky-clean hero a la Optimus Prime. The IDW comic turns him into a [[TheFundamentalist religious fanatic]] who once called for an atheist Holocaust. He works for the BigBad to bring about the end of all artificially-built Transformers, including [[spoiler: his GoodCounterpart, Dai Atlas]], whom he had religious disagreements with. This is a carry-over from the author's days in the Transformers UK fandom, where his stories portrayed Star Saber as a fascist.
** IDW's version of Rattrap, particularly in ''[[ComicBook/TransformersWindblade Windblade]]'', but also present in [[ComicBook/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 ComicBook/XMen, who, in this timeline, aren't mutants, but sociopaths– and [[spoiler: Jean Grey killed Rogue]]. [[spoiler:Professor X himself]] is the BigBad of the sequel miniseries.
** In ''ComicBook/{{Wolverine}} Noir'', the BigBad is [[spoiler: Rose, from Wolvie's mini ''Origin'']].
** In ''ComicBook/SpiderManNoir'', Curt Connors is a Nazi-sympathetic scientist and assistant to Doctor Octopus who remorselessly experiments on humans, very different from his mainstream comics counterpart, who is generally a good guy when he isn't having SuperpoweredEvilSide issues.
* In Threeboot ''Comicbook/LegionOfSuperheroes'', White Witch, Polar Boy and Chlorophyll Kid (as Plant Lad) are all members of the Wanderers, which is an antihero version of the Legion of Super-Villains, a bit like the Light Speed Vanguard in [[WesternAnimation/LegionOfSuperheroes the cartoon]]. In the original continuity, White Witch is a Legionnaire, and Polar Boy and Chlorophyll Kid are founders of the Legion of Substitute Heroes.
* In ''ComicBook/{{Noob}}'', the comic version of Donteuil in regards to the webseries one. When that fact that [[spoiler:Fantöm's avatar was illegally enhanced]] gets 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 comic, 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 that gets no mention in the webseries, provided by someone else than Donteuil.
* In the ''ComicBook/MyLittlePonyFriendshipIsMagicIDW'' 2014 Holiday Equestria Girls Special, the Cutie Mark Crusaders hit this big time as the human version of "Ponyville Confidential" turns quite dark as this version of their gossip column, Anon-A-Miss, was done not out of being blackmailed, but because Applebloom [[GreenEyedMonster grew jealous of Applejack's time with Sunset Shimmer]] and the others followed along with her.
* The BiggerBad in ''ComicBook/{{Nextwave}}'' is [[spoiler: Devil Dinosaur]]. Usually a heroic character, he's now an OmnicidalManiac in charge of a massive terrorist organization, killed and ''ate'' his partner [[spoiler: Moon Boy]] (who is also abusive here), and [[ArsonMurderAndJaywalking he can also]] [[spoiler: [[SuddenlyVoiced speak]]]]. When the events of ''Nextwave'' became part of mainstream Marvel continuity, they were both naturally revealed to be evil clones. All PlayedForLaughs, of course.
* In ''[[ComicBook/TheMultiversity Thunderworld #1]]'', Magnificus Sivana is on his father's side with [[DaddysLittleVillain Junior and Georgia]], while traditionally he's [[MadDictatorsHandsomeSon a good guy]] and friend of the Marvel Family.
