** Dr. Druid has, starting in 1995, had a bad history with this. While his actions during his time as leader of the Avengers and the Defenders were due to the manipulated by Terminatrix and Slorioth respectively, his actions in ''ComicBook/Druid1995'', where he went mad with new powers he gained, were his own. While during ''ComicBook/TheAvengersKurtBusiek'' and ''ComicBook/ChaosWar'', he was among those reanimated by the Grim Reaper and Amatsu-Mikaboshi respectively to be pawns, only to break free, he returned as the tyrant of Weirdworld in ''ComicBook/SquadronSupreme2015'' when he learned he had a body there. Then in ''ComicBook/DoctorStrange, Surgeon Supreme'', he seemed to return for real and want to have a normal life, but the series ended before it could be confirmed if he was telling the truth or lying.

* ''Franchise/MarvelCinematicUniverse'': [[Characters/MCULokiLaufeyson Loki Odinson Loki]] seems to have this problem as of ''Film/ThorRagnarok'' . He spent the first part of his adult life fighting for Asgard, which, [[spoiler: [[DarkAndTroubledPast at that time, at least]]]], played the role of peacekeeper and protector of the nine realms. However, since [[GoMadFromTheRevelation going mad]] after [[InternalizedCategorism learning he is a Frost Giant]], he has [[BigBad mostly played the role of antagonist.]] In ''Film/ThorTheDarkWorld'', however, he [[spoiler: [[EnemyMine helped Thor save the universe]] and [[EvenBadMenLoveTheirMamas avenged Frigga's death]]]], and during ''Film/ThorRagnarok'', the damage he helped cause[[spoiler: to the nine realms was mostly due to [[ItsAllAboutMe inaction as the ruler of Asgard]] [[IHaveNoSon and the actions he took to get back at his father]]]] rather than the [[EvilPlan deliberate malice that characterized his past appearances.]] However, during the course of the third film, he does [[spoiler: [[ChronicBackstabbingDisorder betray Thor again to no one's surprise]], but in the end decides to come back last minute to help save the citizens of Asgard.]] At one point, when Bruce Banner asks him if he still wants to kill everyone like he did the last time they met, he even admits that [[AxCrazy it changes from moment to moment.]] He also seems very confused about whether he still wants Thor dead while he is watching the gladiator match between Thor and the Hulk, alternately cheering when the Hulk hurts his brother, jumping up in concern when he hurts him too much, pretending he isn't concerned, and then cheering the Hulk some more, all in the ridiculously short time span of a few minutes. The constant side-switching appears to be due to the fact that the character himself is very confused, in this case.

*** Magneto, as usual, especially given his FriendlyEnemy relationship with Charles. In the BadFuture, he makes a final peace with Charles. In the past, he plays both sides.

* ''Series/AgentsOfSHIELD'': After being firmly on the bad guy's side in Season 1, [[spoiler: Grant Ward]] spends most of Season 2 bouncing back and forth between helping Coulson's team and hindering them. [[spoiler: However, the season finale seems to have cemented him as a villain, though a version of him in Season 4 ends up squarely on the side of good thus proving both his FreudianExcuse and the circumstances around it being the major contributing factor to his actions]].

* ''ComicBook/SpiderManTrilogy'': In ''Film/SpiderMan3'', Harry Osborn changes sides three times. The first time, he lost his memory in an accident. Once he regained it, he became a bad guy once more. When he finds out how his father ''actually'' died, he redeemed himself.

* [[ComicBook/Warlock1967 Adam Warlock]]'s creator, the High Evolutionary, has a ''very'' long history of this, and his evil quotient will often depend entirely on the book he is in at any given time. Though his character is a fairly stock EvilutionaryBiologist with AGodAmI-level delusions of grandeur, he has been cast as the hero (or at least a heroic figure) several times, such as when he memorably faced ComicBook/{{Galactus}} in the '70s and again in the '90s in run-ins with Mr. Sinister (another Evilutionary Biologist who was retconned into being TheManBehindTheMan to him) and Exodus (who is usually a KnightTemplar AntiVillain, but was {{flanderized}} into a SmugSnake to make the Evolutionary look more heroic). Modern stories have gone back to using him chiefly as a villain, most recently (as of 2017) clashing with the ComicBook/NewWarriors.
* Creator/MarvelComics' version of ComicBook/{{Ares|Marvel}} started as a CardCarryingVillain who was causing wars and conflicts only because he liked it, but was also fighting alongside other Olympians against a common enemy. Then he realized the other gods would never accept him, went to Earth and lived peacefully among the mortals. Then, when his son got kidnapped, he joined the Olympians in the fight against evil Japanese god Amatsu-Mikaboshi. Later he joined one of the incarnations of ComicBook/TheAvengers but often acted like a typical villain towards [[ComicBook/TheIncredibleHercules Hercules]]. [[ComicBook/DarkReign Then]] he joined the ComicBook/DarkAvengers, a team of villains posing as heroes, and was fighting both good and bad guys as well, while being one of the few members who were treating the heroic part seriously. At the same time he was training a team of killers for ComicBook/NormanOsborn and let his son join ComicBook/NickFury, who was opposing Osborn. Then he [[spoiler: betrayed Osborn after finding out he lied to him about Asgard being ruled by Loki and died, fighting alongside Norse Gods he was beating minutes ago]]. Then he returned after ''ComicBook/SecretWars2015'' in ''ComicBook/ContestOfChampions2015'' on the good guys' side.
* Armadillo; originally a low level thief mutated into a humanoid armadillo by [[MadScientist Dr. Karl Malus]], he fought Captain America but reformed at the end because he wasn't really an evil guy. In his next appearance, he temporarily went mad as his wife [[UngratefulBastard (whom he underwent the mutation to get money to save from illness)]], cheated on him, with Cap again forced to stop his rampage. Since then, he's appeared throughout the Marvel Universe, usually serving as DumbMuscle for various villains, but has also been an MMA fighter (in ''ComicBook/{{Thunderbolts}}''), a rodeo performer, and even joined a hero team in ''ComicBook/{{Civil War|2006}}''. His most recent appearances have had him working with the Hood's crime syndicate, & as part of HYDRA's "Army of Evil" in ''ComicBook/SecretEmpire''. He then betrayed HYDRA on the advice of Sam Wilson, only to go on another rampage when he realised the heroes weren't putting much effort into finding a cure for him either. [[note]] Perhaps justified as, being a large armadillo man, it is probably hard for him to get legitimate work, and supervillains are likely the only ones to hire him. [[/note]]
* ComicBook/{{Magneto}}'s children ComicBook/{{Quicksilver}} and the ComicBook/ScarletWitch started as members of the [[ExactlyWhatItSaysOnTheTin Brotherhood of Evil Mutants]] then reformed and joined ComicBook/TheAvengers and have been ping-ponging back and forth between heroism and villainy ever since. Quicksilver primarily because he'd really like to be a hero but is too self-centered to not do something he thinks will improve his situation just because it's illegal or wrong or something; Scarlet Witch primarily because she has a [[WithGreatPowerComesGreatInsanity mental breakdown]] whenever a writer can't think of something more interesting to do with her [[WindsOfDestinyChange near-omnipotent]] powers.
* Baron Helmut Zemo, LegacyCharacter to unrepentant Nazi Heinrich Zemo and archenemy of ComicBook/CaptainAmerica and the Avengers as a whole, struggles with this. He believes himself to be a WellIntentionedExtremist who would [[UtopiaJustifiesTheMeans make the world a better place by ruling it]]. He constantly stresses over [[EvenEvilHasStandards the few morals he has]] and can't seem to make up his mind as to whether he should be a hero or villain. He's gone from villain to villain pretending to be a hero to AntiHero and back around again. Sadly, in the end [[FatalFlaw his massive ego and cynicism]] keeps him from becoming the truly great hero he has the potential to be.
* ComicBook/{{Deadpool}} wavers between mercenary, good guy, or doing merc work for the bad guy of the week. In recent years, Deadpool has been trying very hard to be more of a hero, especially after his long-lost daughter, Ellie, comes back into his life. This put him at odds with his wife, Shiklah, who wants him to stay the killer she married. He has fallen off hard again by accidentally siding with Hydra in Secret Empire. [[spoiler: WordOfGod came out and talked about the new series, entitled ''ComicBook/TheDespicableDeadpool'', which will be a part of Marvel Legacy. WordOfGod states that Deadpool will be ostracized for his mistakes in Secret Empire, and will receive no credit for the things he did to help rectify the situation. Thus, he will finally give up on being a hero, and return to his roots as a mercenary.]]
* Dr. Druid has, starting in 1995, had a bad history with this. While his actions during his time as leader of the Avengers and the Defenders were due to the manipulated by Terminatrix and Slorioth respectively, his actions in ''ComicBook/Druid1995'', where he went mad with new powers he gained, were his own.

Then in ''ComicBook/DoctorStrange, Surgeon Supreme'', he seemed to return for real and want to have a normal life, but the series ended before it could be confirmed if he was telling the truth or lying.
* ''ComicBook/{{Eternals}}'' has Kro, the immortal Deviant who’s been the ruler of Lemuria on more than one occasion. Sometimes he’s been a clear villain, sometimes he’s been portrayed as a reasonable, if pragmatic leader who just wants the best for his people. He’s been an ally of the Eternals - and of the US government, with an office in the Pentagon and a project to peacefully integrate Deviants into human society. And he’s also been the shadowy mastermind unleashing {{kaiju}} on human cities for no particular reason. Kro’s complicated.
* Ghost. He started out as an ComicBook/IronMan villain, but during Comicbook/DarkReign he worked against Norman Osborn from within the ComicBook/{{Thunderbolts}} and was instrumental in taking him down. Of course, this was immediately followed by him trying to kill Tony Stark yet again. Several times. He subsequently became one of the most heroic of the post-Dark Reign Thunderbolts, despite trying to kill Tony Stark. Again.
* ''ComicBook/TheIncredibleHulk'': Due to his simple and unstable psyche and tendency to go into blind rages, the Hulk has gone from hero to villain and back again his entire existence. For instance, Hulk will save a city one minute, then someone (typically his nemesis General Ross) will piss him off and he'll start ripping apart the city he just saved. In the end though, Hulk will usually end up doing the right thing, even if it's just by accident.

** Betty Ross as Red She-Hulk has pulled one of those in "Super Spy Banner" and "Heart of the Monster". She's a Face for good in the end of "Heart of the Monster". And then she seemingly resumes Heel status after becoming Red Harpy, only for it to turn out she is actually Face.
* [[ComicBook/SubMariner Namor the Sub-Mariner]] deals with this so often that the trope may as well be named The Namor. He fought the original Human Torch (that's bad) and allied with him against the Axis in World War II (that's good) then swore revenge against humanity when he thought they'd destroyed Atlantis (that's bad) then swore to defend Atlantis once it was discovered again (that's good), and [[WesternAnimation/TheSimpsons the frogurt is also cursed (that's bad)]]. To put it another way: Marvel currently has two "ruling councils" of good guys and bad guys. Namor is on both of them. There have been occasional efforts to explain Namor's moral flexibility as a psychosis induced by his biology (he's a human/Atlantean hybrid and a mutant) and/or his amphibious environment. On balance, though, readers and creators prefer him being a treacherous dick because that's just who he is.
** To expand on some of Namor's more recent history: Turns out he had sleeper-agents in America (bad), but then he helps Captain America's side in the ''ComicBook/{{Civil War|2006}}'' and promises to have all sleeper agents removed (good), he lied about the sleeper agents (bad), successfully stops his son Kamar from an attempted coup and starting a war with America (good), unfortunately this chain of events leads to Atlantis being destroyed and Namor has reforging his alliance to Doctor Doom and now the Atlantean military is based in Latveria (bad), both men join Norman Osborn's Cabal and Namor attacks Tony Stark at the behest of Osborn (also bad), but them Namor (in alliance with Emma Frost) betrays ComicBook/NormanOsborn and joins the X-Men and helps them setup and defend Utopia (good), later he becomes one of the five X-Men possessed by the Phoenix Force (who are all going a bit AGodAmI now and the the [[BigBad Big Bads]] of ''ComicBook/AvengersVsXMen'') and stages an unprovoked invasion of Wakanda (very bad).
* ComicBook/TheSentry went back and forth endlessly between being the universe's greatest hero, its greatest threat, or both at the same time. He was a bundle of mental issues even without factoring in The Void (which was either a SplitPersonality, an EvilCounterpart that was created when he gained his powers, or his true self), so it's no surprise that his Heel-Face status is as unstable as the rest of him. After some years of this, the narrative finally settled on "greatest threat" in ''ComicBook/{{Siege}}'', where he merged with the Void and became a HumanoidAbomination. He then died and got reborn (again) as one of the Final Horsemen of Apocalypse, which would seem to close the door on him once and for all, but ComicBook/DoctorStrange managed to bring him back to the side of good.
* ''Franchise/SpiderMan'':

*** The character "Toxin" was created to fit the other end of the Venom scale. Toxin is the symbiote child of Carnage who bonded onto a law-abiding police officer. While the struggle with the symbiote's natural killing desire is intense, Toxin is a more straight example of a heroic Venom.

* ComicBook/UltimateMarvel:

** Chuck Austen, of all people, got the [[ComicBook/JuggernautMarvelComics Juggernaut]] caught in one of these, introducing a redemption arc for the character that was one of the few positively-received elements of his ''X-Men'' run. Juggs eventually went back to villainy due to StatusQuoIsGod, but for a good long while there you could flip a coin to figure which side of the hero/villain line he was going to be on. Even after a hard HeelFaceDoorSlam he is still on an uneasy frenemy status with some X-Men, most notably Havok (who was one of his strongest defenders in the Austen run) and Nightcrawler (who hesitated to call Cain an enemy even after being used as a hostage by him). The 2020 ''Juggernaut'' miniseries portrays him as fundamentally directionless (ironically for a character defined by being unstoppable) and trying to figure out what he actually ''wants'' to be doing.
* It's a fairly well documented fact that any time a villain becomes popular enough, Marvel will take a stab at making them a hero, or at least an anti-hero. The most ridiculous example: their repeated (at least three times) attempts to make sociopathic casual killer and [[DependingOnTheWriter rapist]] Sabretooth into an X-Man. At least they recently seem to have realized that rehabilitating him will never pan out, and resorted to [[ExplosiveLeash coercing]] him into behaving himself. Although there have been at least two alternate universe versions that exist primarily to allow a heroic Sabretooth without all the baggage.
** And now there's a flashback storyline running, from a period when Sabretooth was somewhat less insane (presumably, the processes that Weapon X had used to control him when he was an assassin hadn't completely worn off yet) and not yet in a blood feud with Wolverine, in which he's a PunchClockHero. He doesn't much care about helping young mutants, but as long as the checks keep clearing...
** ''ComicBook/{{AXIS}}'' seems to be trying to make this stick, as he's the only villain whose Inversion stuck, thanks to being caught in a special barrier made by the Superior Iron Man. He realizes this is a second chance and seeks to find his Inner Wolverine by becoming part of [[ComicBook/UncannyAvengers the Avengers Unity Squad]].
** The latest update from ''ComicBook/XMen2019'' is that Sabretooth, back to his evil ways, manages to break Krakoa's first law (no killing humans) before it's even codified. He's sentenced to living entombment underneath the island -- and it's heavily implied the ruling Council handed down this punishment because they knew he, out of '''all''' mutants, would be least likely to follow the new laws.

* ''Film/SpiderMan3'': Harry Osborn changes sides three times. The first time, he lost his memory in an accident. Once he regained it, he became a bad guy once more. When he finds out how his father ''actually'' died, he redeemed himself.
* Loki seems to have this problem as of ''Film/ThorRagnarok'' . He spent the first part of his adult life fighting for Asgard, which, [[spoiler: [[DarkAndTroubledPast at that time, at least]]]], played the role of peacekeeper and protector of the nine realms. However, since [[GoMadFromTheRevelation going mad]] after [[InternalizedCategorism learning he is a Frost Giant]], he has [[BigBad mostly played the role of antagonist.]] In ''Film/ThorTheDarkWorld'', however, he [[spoiler: [[EnemyMine helped Thor save the universe]] and [[EvenBadMenLoveTheirMamas avenged Frigga's death]]]], and during ''Film/ThorRagnarok'', the damage he helped cause[[spoiler: to the nine realms was mostly due to [[ItsAllAboutMe inaction as the ruler of Asgard]] [[IHaveNoSon and the actions he took to get back at his father]]]] rather than the [[EvilPlan deliberate malice that characterized his past appearances.]] However, during the course of the third film, he does [[spoiler: [[ChronicBackstabbingDisorder betray Thor again to no one's surprise]], but in the end decides to come back last minute to help save the citizens of Asgard.]] At one point, when Bruce Banner asks him if he still wants to kill everyone like he did the last time they met, he even admits that [[AxCrazy it changes from moment to moment.]] He also seems very confused about whether he still wants Thor dead while he is watching the gladiator match between Thor and the Hulk, alternately cheering when the Hulk hurts his brother, jumping up in concern when he hurts him too much, pretending he isn't concerned, and then cheering the Hulk some more, all in the ridiculously short time span of a few minutes. The constant side-switching appears to be due to the fact that the character himself is very confused, in this case.

* ''Film/XMenFilmSeries''

* ''[[VideoGame/UltimateSpiderMan2005 Ultimate Spider-Man]]'' has ComicBook/SilverSable going from attacking Peter now that she knows he's the titular hero to helping him save the innocents to attacking him again to finally letting him go after Trask.

** ComicBook/{{Mystique}}, with an actual revolving door reference [[http://www.evil-comic.com/archive/20081009.html here]]. She's been a CardCarryingVillain, federal agent, terrorist, spy and full-fledged X-Man at various times, and that's not even getting into her ExpansionPackPast.

He's sentenced to living entombment underneath the island -- and it's heavily implied the ruling Council handed down this punishment because they knew he, out of '''all''' mutants, would be least likely to follow the new laws.

** The final two Avengers movies add even more to it. [[spoiler:In ''Film/AvengersInfinityWar'', he continues the heroic streak he started from the end of Ragnarok and takes it all the way until the end of his life. He is ultimately DefiantToTheEnd and dies heroically against Thanos in his effort to save Thor. While this means that Loki died a hero because he was KilledOffForReal there, ''Film/AvengersEndgame'' has the heroes go back in time to the end of the first Avengers, where they run into Loki when he was at his most evil. Past Loki escapes with the Tesseract and is never caught, meaning that past Loki could return as a villain later even though present Loki died a hero. Which gets followed up away from the films in the Disney+ ''Series/{{Loki}}'' series]]

* Creator/MarvelComics' version of ComicBook/{{Ares}} started as a CardCarryingVillain who was causing wars and conflicts only because he liked it, but was also fighting alongside other Olympians against a common enemy. Then he realized the other gods would never accept him, went to Earth and lived peacefully among the mortals. Then, when his son got kidnapped, he joined the Olympians in the fight against evil Japanese god Amatsu-Mikaboshi. Later he joined one of the incarnations of Comicbook/TheAvengers but often acted like a typical villain towards [[ComicBook/TheIncredibleHercules Hercules]]. [[ComicBook/DarkReign Then]] he joined the ComicBook/DarkAvengers, a team of villains posing as heroes, and was fighting both good and bad guys as well, while being one of the few members who were treating the heroic part seriously. At the same time he was training a team of killers for ComicBook/NormanOsborn and let his son join ComicBook/NickFury, who was opposing Osborn. Then he [[spoiler: betrayed Osborn after finding out he lied to him about Asgard being ruled by Loki and died, fighting alongside Norse Gods he was beating minutes ago]]. Then he returned after [[ComicBook/SecretWars2015 the 2015 Secret Wars]] in the ComicBook/ContestOfChampions on the good guys' side.

* Franchise/{{Batman}} villain ComicBook/TwoFace literally flips a coin to determine whether he'll do something good or bad. Harley Quinn has also had more than one failed reformation, mostly due to her lingering, err, ''affections'' for ComicBook/TheJoker -- himself probably the Batman villain ''least'' likely to have a HeelFaceTurn.
*** Whenever Harley has [[ComicBook/HarleyQuinn her own series]], the writers work around this by generally reserving her homicidal tendencies for ''other villains''. Good guys and innocent victims usually end up knocked out or BoundAndGagged at worst. {{Asshole Victim}}s on the other hand....
** ComicBook/PoisonIvy, while always a villain when on her own, tends to reform (or at least become neutral) whenever Harley is attempting to reform.
*** She was even a member of the ComicBook/BirdsOfPrey. Though that was entirely for selfish reasons, and she betrayed her teammates once she no longer got anything out of the deal.
** In his very first appearance, Two-Face had captured Batman and was throwing the coin for whether to kill or free him. Batman asked what if the coin stood on its edge? and got Two-Face to agree to surrender and submit to plastic surgery and therapy. The coin -- substituted by Batman for the real coin -- stood on its edge, and Two-Face returned to a normal life. However, he was later injured again and returned to his life as Two-Face.
*** [[RecycledScript ANY time Two-Face gets his face restored or tries to give up on his evil personality, he always goes back to his old ways.]] One was even helped along by [[spoiler: the Joker.]]
** In [[ComicBook/BatmanNoMansLand No Man's Land]] an act of ungodly luck makes Two-Face a good guy for what looks like weeks if not months. He agrees to help Renee Montoya to try and take care of the weaker people in the city; injured, old, children, etc. Each time he helps he flips a coin, according to Montoya he apparently flips the "good" side over 100 times......in a row. It's possible that the implication there was that Two-Face was cheating. Perhaps he had honestly (temporarily) reformed, but pretended it was all the coin's fault (so he'd have an excuse if he ever turned evil again). And if that's not it, maybe Batman or Montoya just slipped him a weighted coin.
** ComicBook/TheRiddler sometimes went through the door as well, though currently he's a Face. It's unknown whether he will become a Heel again.
* This Trope could also be named The ComicBook/BlackAdam. He started out as a champion of his people in ancient times named Mighty Adam (that's good) then became a brutal dictator and conqueror when his family was killed by a supervillain (that's bad) then millennia later attempted to reform and even joined the ComicBook/JusticeSocietyOfAmerica (that's good) then became a not-so-brutal dictator of his country again (NOT the bad part) and later joined a Society of Villains to ensure their safety (that's bad). After said Society betrayed him, he later fought against them when they tried to take over Metropolis (that's good) then went back to being a harsh dictator with plans to form a new Axis Powers coalition (that's bad). When he gained a new family he tried to go back to his old heroic ways and traveled the world fighting evil alongside them (that's good). When this family was killed by supervillains he went on a RoaringRampageOfRevenge, ''murdered an entire country'', and fought every superhero on Earth (that's bad, but awesome). Most recently, his wife CameBackWrong and started turning his people into dirt and he tried to defend them [[spoiler: leading to a truly bizarre situation with ''Black Adam'' defending innocents from the ''corrupted [[ComicBook/{{Shazam}} Captain Marvel]] and Mary Marvel'']] (that's good.) Then he got turned into a statue alongside his wife for his troubles [[spoiler: and an oh so ominous shadowy figure wants to make them his champions...(that's bad)]]. At least there's a free choice of toppings (that's good)...that contain potassium benzoate (...that's bad). By the Power of Shazam, that is one busy revolving door.
** [[ComicBook/{{Shazam}} Mary Marvel]] herself applies in ''ComicBook/CountdownToFinalCrisis'', starting out good, getting corrupted by Black Adam's power, doing a HeelFaceTurn, gaining her old powers back, and then moronically deciding to accept Black Adam's power and turn evil again after Darkseid has a friendly chat with her ([[http://readrant.files.wordpress.com/2008/04/couch-got-an-empty-spot-with-your-name-on-it-girl.jpg no, that's not a euphemism]]). And then she [[SugarWiki/FunnyMoments beats up Donna Troy]] [[GrievousHarmWithABody using Kyle Rayner as a club]], among other evulz. If you're wondering, this is just one reason for why 90% of the events of ''Countdown'' are subjected to a blanket decree of LetUsNeverSpeakOfThisAgain both [[CanonDiscontinuity in canon]] and [[FanonDiscontinuity out.]]
* Captain Boomerang Jr. from Franchise/TheDCU. He started out as his father's replacement in [[ComicBook/TheFlash The Rogues]], then tried his hand at being a hero as a member of Nightwing's Outsiders. When he and Dick got into an argument about what to do with Chemo, the living chemical weapon that destroyed Bludhaven, they got into a fight and Owen absconded with Chemo to join the Suicide Squad. In ''ComicBook/BlackestNight'', Owen's desire to be with his father again overrode his morals. He fed people to his zombie father, wrongly believing that this would revive him. Including women and children, [[EvenEvilHasStandards which prompted Captain Cold and the other Rogues to kill him.]] Cold lampshaded Owen's Revolving Door nature, saying he was like a boomerang going back and forth everywhere.
* ComicBook/{{Catwoman}} has been this for decades. Though she had settled on "antihero" in the 90's, the [[ComicBook/New52 modern age]] once again made her an AntiVillain who occasionally does good things.
* The Enchantress (June Moon) was introduced in Creator/DCComics' ''Strange Adventures'' as a heroine. Then she became a ComicBook/{{Supergirl}} villain. Following from that, she became a member of the Forgotten Villains, and then she joined the ComicBook/SuicideSquad, at which point it was established that June was a good person but the Enchantress was her SuperpoweredEvilSide. In ''Day of Judgement'', Enchantress is an amoral character who has to be pressurised into saving the world from Hell. During this the Enchantress is "killed", leaving June Moon. Later, in a ''JLA'' miniseries, they're merged together to form Soulsinger, and then separated again, but the powers stay with June, giving us the heroic Enchantress seen in ''ComicBook/{{Shadowpact}}''.
* Dr. Alchemy/Mr. Element (Al Desmond) showed signs of this during the Silver Age of ''Franchise/TheFlash''. He reformed after his first appearances, took up a white-collar job, and became good friends with Barry Allen, even attending his wedding. Meanwhile he was pulled back into evil, or sometimes just framed for it, by everything from Professor Zoom (twice!) to the fluctuations of a distant star to the machinations of a psychic twin (who turned out to be his own split personality given shape post-Crisis).
* ComicBook/LadyShiva wavers between anti-hero or villain.
* ''ComicBook/RobinSeries'': Despite his short tenure Dodge's desire to be special leads to him stealing a prototype teleporter which he uses to try and become a hero. When he screws that up he blames it on Robin and becomes a villain who sells fatal experimental drugs to finance his "revenge". Then after one of the villains he recruits for his revenge plot takes over from him and the Teen Titans have all but defeated his crew he switches sides claiming to have always wanted to be a hero and seems to die in a teleporter accident fighting the mutineer.
* Professor Emil Hamilton was introduced to ''Franchise/{{Superman}}'' comics as a MadScientist who attacked Superman after ComicBook/LexLuthor took credit for his inventions, in order to [[TheyCalledMeMad show them all]]! After responding well to therapy, he became Superman's science advisor. When [[ComicBook/{{Steel}} John Henry Irons]] started taking on that role, Emil went mad again and became the villain Overmind, although he blamed this on being taken over by B-13 technology through his [[ArtificialLimbs robot arm]]. Once this was dealt with, he and John Henry worked together, thanks to Emil's better understanding of B-13 tech. Then he became convinced that Superman's powers were sucking energy from the Sun and reducing the viable lifespan of the Earth, so he became the WellIntentionedExtremist villain Ruin and crossed the MoralEventHorizon by targeting Clark's loved ones. And that was the last time we saw him before ''ComicBook/{{Flashpoint}}''.
** And now in ''ComicBook/{{Convergence}}'', he appears to have reformed again, describing working on Jimmy Olsen's [[Creator/JackKirby Whiz Wagon]] vehicle as occupational therapy.
* ''ComicBook/TeenTitans'':
** ComicBook/{{Raven}} who's turned evil and been redeemed or cleansed of evil about 4 times and counting by now. Most of this has to do with attempts to recapture the success and impact of the first time it happened in the Wolfman/Pereze Titans run. That time it was subtly built up over months. The later ones? Eh, they just sort of happen in a rather transparent attempt to drive up sales. Her Face/Heel turning points almost make her TheMillstone of {{Heel Face Revolving Door}}s if only for the transparency of her subsequent changes.
** Fellow Titan Jericho is just as bad. He started out good but was driven insane by evil spirits from Raven's father's home dimension. After his father killed him to stop his rampage Jericho clung to existence as an evil spirit being. Years later he was revived and purified of his evil. Then he went evil again due to spending too much time in Superboy's clone Match. Now, he's well...kind of a mess to be honest. It's not clear at this time whether he's good, evil, or even functional.
* ''Franchise/WonderWoman'':
** Ares flips betwixt CardCarryingVillain, AntiVillain, impartial bystander and occasional AntiHero. While he has had at least one turn attempting to be an actual proper hero in ''ComicBook/WonderWomanRebirth'' his very nature means he can't meaningfully operate as such and his attempt warps him into a vicious KnightTemplar, meaning he's at his best when he's snarky, occasionally cruel and keeping his true intentions well hidden as something closer to an AntiHero.
** ComicBook/HerculesUnbound does try to be heroic most of the time, but often by the standards of Ancient Greek mythology, making him come off as an outright villain to modern sensibilities. While he does occasionally get it right it never seems to last.
