[-[[caption-width-right:350:King Dedede in [[Franchise/{{Kirby}} the games]] vs. King Dedede in [[Anime/KirbyRightBackAtYa the anime]].]]-]

* The ''Anime/AceAttorney'' anime, while keeping the same story as the games, turns Morgan Fey into even more of a villain than she was in the games. In the "Reunion, than Turnabout" case in the game, Morgan is partnered with Ini Miney, cooperating with her to get Maya arrested for murder, while Ini simply wants to kill Dr. Grey [[spoiler: to protect the secret that she is, in fact, Mimi Miney]]. However, in the anime, Ini doesn't want to kill Doctor Grey, she just wants to fake the channeling so he doesn't find out that secret. Morgan, however, comes up with the plan to kill Doctor Grey and frame Maya for it. When Ini refuses, Morgan threatens to [[spoiler: reveal Ini's secret identity.]]
* In the original ''VideoGame/ArtOfFighting'' game, King was a reluctant PunchClockVillain who gave Ryo and Robert information needed to rescue Yuri after being defeated, with her later appearances firmly establishing her as one of the good guys. In the anime film, she's an unambiguous villain and the one who actually kidnaps Yuri (at Mr. Big's behest) in the first place.
* Annie Leonhart from ''Manga/AttackOnTitan'' is a ruthless killer in both anime and manga, but the manga goes further to portray her AntiVillain status, giving her more humanizing moments such as genuinely smiling at one point, mentoring Eren Jeager in hand-to-hand combat, and also looking visibly shaken when she accidentally kills civilians. All of these moments are removed from the anime while also increasing the number of people she kills. It's not unusual to hear people say they hate her after watching the anime, then they read the manga and start sympathizing with her.
* The first anime of ''Manga/BlackButler'' does this with Queen Victoria, of all people. In the manga she's a straight CoolOldLady [[spoiler: though she seems to like the idea of a Zombie army]], while in the anime she's [[spoiler:responsible for Ciel's parents' deaths, and planning to start a world war to "cleanse" the world with her angelic accomplice, Ash. It is, at least, implied that she's not at all stable, in part due to Ash's machnations]].
* In the ''Manga/{{Bokurano}}'' manga, Koyemshi/Dung Beetle is quite a jerk throughout, but he has a few PetTheDog moments, such as performing a MercyKill on [[spoiler:his sister, Youko]], and giving Ushiro reasons to fight. In the anime, he's significantly more vicious, including mocking one of the dead kids, was quite a DirtyCoward [[spoiler:while he was a human]] and ultimately [[spoiler:gets killed by his aforementioned sister when he tries to force the youngest of the group into the game]].
* ''Anime/BombermanJetters'' famously changed Max from a FriendlyRival into a ruthless villain while doing [[AdaptationalHeroism the reverse]] for game series primary BigBad, Bagular.
* More like "Adaptational Antagonism", but Leon MacNicol in the ''Anime/BubblegumCrisis'' OVA was supportive of the Knight Sabers, but much like George Stacy towards Spider-Man in relationship to their comic counterparts in ''Film/TheAmazingSpiderMan'', Leon in the ''Tokyo 2040'' remake considers the team vigilantes and a blight on the AD Police.
* In the manga version of ''Manga/ChronoCrusade'', BigBad Aion is portrayed as misguided and possibly insane, but sympathetic, having turned to evil deeds in a desperate attempt to fix what he felt was a corrupted system after learning an AwfulTruth. In the anime, he was turned into the literal AntiChrist.
* [[TricksterMentor Cross Marian]] of ''Manga/DGrayMan''. In the manga, he was a victim of JerkassFacade at best, or a JerkWithAHeartOfGold at worst. But the anime, done by TMS Entertainment, decided that they wanted him to be a complete JerkAss. Episode 27: My Master, General Cross is infamous for the villainization of Cross' character -when Allen begins to tell Lenalee tales of how horrible his master is, so she'll know what to expect when they find him. The includes things from Cross that actually contradicted his manga characterization and WordOfGod.
** In the aforementioned episode, Cross is shown forcing Allen into slave labor to make money, whereas in the manga, Allen only gambled to make money. Also, in canon Allen mentioned he only gambled if he and Cross were very broke. But in the episode, Cross forces Allen to gamble and steals his money when he's living off of a rich lover at the time. Allen mentions that his master was lover to a Maharajah's widow because he has a thing for rich women. WordOfGod however, has stated that Cross likes good women, not rich women. We also see Cross telling Allen to bring him a lion, which almost gets Allen killed, in addition to throwing Allen to legions of Akuma without training him. And Allen mentions that given Cross' treatment of him, he battled with depression as a result, only finding happiness with Narain, a friend he met in India.
** Filler episode 25 Allen is shown to have a severe mistrust of all Exorcist Generals -saying that due to his bad experience with Cross, he didn't believe Generals were good people. There was also a scene where Yeegar speaks to Allen about Cross, saying that he is the best at destroying Akuma, but isn't good at human interaction. Neither of these scenes were in the manga, and contradicted the canon of General Yeegar already being dead before Allen and Lenalee are sent to find Cross.
** Changes were also made to canon scenes where Cross is shown doing things in them that weren't in the manga. Such as the guards dragging Allen out of Cross' room at HQ. In the manga, Cross just watches as Allen is taken away. However in the anime, he smirks and hums mockingly while waving Allen off. In addition to stealing food from the cart of the vendor he spoke to in Krory's village -which he wasn't shown doing in the manga.
** In Hallow -the 2016 continuation, there were cases of scenes and lines being cut. In the manga, Cross hugs Allen, saying he wishes Nea had chosen another host as his vessel. Then he says he can't laugh at Tiedoll's open affection for his students in longer. He's also shown wondering is sacrificing one thing always has to be done to protect something else, which hints he sees it as a case of IDidWhatIHadToDo. In the anime, Cross just tells Allen he's going to kill someone he loves when he becomes the 14th. Hie 2 lines about Tiedoll and DirtyBusiness are complete skipped over.
** Finally, both anime adaptations have a habit of changing Cross' facial expressions to include him smirking or scowling when he wasn't in the manga. One such example includes Hallow's episode 13, which adapts the flashback chapter 206, with Cross caring for young Allen. In the manga, toward the end, we see Cross sitting with Allen in the bedroom, and he has a sad expression on his face as he watches the traumatized Allen. In the anime's episode, [[http://ic.pics.livejournal.com/silverfang2/29185537/933115/933115_original.png Cross is shown watching Allen with a scowl on his face instead.]]
* ''Anime/DanganRonpa3'' does this to Mukuro Ikusaba. LightNovel/DanganRonpaZero and Dangan Ronpa If ended up having her be portrayed more sympathetic and she ended up performing a HeelFaceTurn in the latter work. Here, this show seems to downplay her sympathetic qualities and instead focuses a lot on the thoroughly reprehensible actions she committed as an accomplice in her sister's schemes. It is extremely noteworthy that she stated that Makoto Naegi (aka her crush and the person who was responsible for her HeelFaceTurn in Dangan Ronpa If) is a loser that is better off dead.
* In the manga of ''Manga/DeadmanWonderland'', the staff of the titular prison HandWave the prisoner deaths in the dog races by claiming that they are done with special effects. In the anime, the special effects angle is done away with; and the prison openly admits that many of the competitors do not survive and die brutal deaths.
* ''Manga/DeathNote'':
** While Light Yagami was always a VillainProtagonist in the anime and manga, he started out sympathetic and [[WellIntentionedExtremist well-intentioned]]. In the live-action films, he ends up JumpingOffTheSlipperySlope much sooner than in the anime and manga, to the extent that unlike his anime/manga counterpart, he's perfectly willing to personally kill his ''own father'' to prevent the Death Note from being analyzed.
** While Ryuk could hardly be considered a hero in the anime or manga, he's much more monstrous in [[Series/DeathNote the live-action TV drama]]. In the anime/manga, he just randomly dropped the [[ArtifactOfDoom Death Note]] and Light picked it up by chance, with Ryuk just kicking back and watching as Light carried out his plans. In the TV drama, he deliberately drops the notebook near Light and serves as TheCorrupter, goading Light into killing more people when he hesitates, effectively making him responsible for Kira's existence.
** L is likewise subject to this in the TV drama. Though not exactly a 'hero' (with WordOfGod admitting that he's a bit evil), he usually comes across as [[ALighterShadeofGrey A Lighter Shade of Gray]] when compared to Light and a few spin-offs (namely the film L: Change the World and the light novel Another Note) [[AdaptationalHeroism portray him more sympathetically]]. The drama by contrast draws more attention to the amorality of his actions and he generally is far more smug and arrogant than most portrayals.
* ''Anime/DragonBallSuper'':
** In his debut in ''[[Anime/DragonBallZBattleOfGods Battle of Gods]]'', Beerus was goofy and likable, though he did have moments of being a JerkassGod. Here, his more sympathetic qualities are toned down while his JerkassGod aspects are ramped up, doing such things as actively destroying planets after eating all their food, outright saying he ''never'' gets tired of watching planets explode after he blows them up, and going out of his way to be a dick to Vegeta and intimidate him after crashing Bulma's birthday party. Most notably, unlike in ''Battle of Gods'' where his slapping Bulma was more reflexive than anything, in ''Super'', after Bulma slaps him, he actually turns towards her and outright backhands her across the face, all with a SlasherSmile and a glint in his eye. After the ''Battle of Gods'' adaptation, Beerus is made more in line with his film counterpart.
** In ''[[Anime/DragonBallZResurrectionF Resurrection 'F']]'', while Tagoma was definitely a villain, being a member of Frieza's army, he showed signs of being a NobleDemon, valuing his commander, sparing the Pilaf Trio even after stealing one of their wishes (two in ''Super''), and [[EvenEvilHasStandards showing a reluctance to revive Frieza due to how evil he was]]. While he's initially much the same in ''Super'', unlike the film, where Frieza had him ThrownOutTheAirlock for daring to speak out against his [[RevengeBeforeReason revenge plan against Goku]], he survives this suggestion, only to be forced into becoming Frieza's personal training dummy; after spending the next four months being beaten within an inch of his life by Frieza ''every single day'', Tagoma not only becomes the strongest member of Frieza's army, but [[BeingTorturedMakesYouEvil a psychopathic monster on par with Frieza himself]], to the extent that he unhesitatingly shoots through Shisami to get to Gohan.
** In the anime, Zamasu wants to murder his master Gowasu, steal Goku's body before killing him and his family, then travel to Future Trunks timeline to kill all the gods and mortals [[EvilIsPetty all because Goku defeated him in a sparring match]]. His reasons to do this is even more petty in the manga; He watched the match between Goku and Hit and becomes enraged that a mortal Saiyan like him managed to attain so much power.
* Bandou was a victim of this in ''Anime/ElfenLied'': He was more a JerkWithAHeartOfGold in the manga. He was humanized through his relationship with Mayu and Nana. Mayu brings him food on the beach, and they are shown eating together. He saves Mayu from being raped by The Unknown Man. Then he sees Nana has been injured by one of the Unknown Man's spike balls. Since she is a Diclonius, he knows it would be troublesome for her to go to a hospital, so he treats her wound instead. He also [[HeroicSacrifice risks his life]] to save Mayu from Lucy, giving up his chance for revenge against Lucy. In the anime,his part is drastically shortened, and any sympathetic or good moments were omitted, while adding in filler to make him seem more cruel.
* The 2003 ''Anime/FullmetalAlchemist'' anime has several cases that were due to those characters not having been well established yet in the [[Manga/FullmetalAlchemist original manga]] when the [[OvertookTheManga anime overtook it]].
** Basque Grand's backstory in the manga showed him as a ReasonableAuthorityFigure and ColonelBadass. His anime version, not having any backstory, is a ColonelKilgore who wants to expand Amestris' military might and does some extremely unethical things to accomplish it.
** Kimblee, who had only shown up in a single manga panel when the anime caught up, ended up being a completely different person. The manga version turned out to be an AffablyEvil sociopath with [[MoralSociopathy a very odd (but very consistent) moral philosophy]], while the anime version became a MisanthropeSupreme and a StrawNihilist who just wanted to kill people because life was inherently meaningless.
** Even Hohenheim, the BigGood in the manga, became a RetiredMonster; instead of being [[UnwittingPawn tricked]] into helping Father turn the nation of Xerxes into a Philosopher's Stone, and only becoming aware of the plan once it was too late to stop it, the anime's backstory has him willingly helping Dante turn people into Philosopher's Stones to prolong their own lives.
** Wrath and Envy were already horrible monsters in the manga, but the anime made them worse. Wrath (now named Pride) loses all of his NobleDemon qualities and his last scene involves him ''strangling his MoralityPet'', [[spoiler:[[OffingTheOffspring his son]]]], Envy had his sadism cranked to maximum, and both lose their AlasPoorVillain moments.
** Barry the Chopper, while AxCrazy in both the manga and first anime, was more of a neutral character in the former and even joins forces with Mustang before his death after realizing that he's going to be hunted down for his connection to the Fifth Lab anyway. The 2003 anime's Barry unrepentantly sides up with anyone who can help him kill as many innocent people as possible, joining up on a mission to slaughter a settlement of Ishvalans forcing Scar to step in and put him down.
** Yoki in both versions starts out as a small-time villain who ends up disgraced by the Elrics, which leads him to rat out Scar to reclaim his status. There the similarities end--the manga ultimately has him becoming a reluctant and (generally) not very helpful good guy, [[spoiler: while the anime has him [[DeathByAdaptation killed by Lust]] to incite a riot between the military and the Ishbalan refugees]].
** In the manga, Scar's [[PosthumousCharacter long-dead brother]] was an idealist whose alchemical research was motivated in large part by his desire for peace. In the 2003 anime, he became something of a MadScientist willing to sacrifice his own people in order to revive his dead lover, though he retained his genuine love for his brother.
* ''Anime/GirlsUndPanzer'' has a few examples from the manga adaptation.
** An odd example comes with Anchovy, since the manga was released before the anime showed her match with Oarai. In the anime, Anchovy's competitive but fairly good-spirited, and after losing, invites the Oarai crew to eat with her and the people who set up the match. In the manga, she starts off by accusing Miho of having a "weak" way of tankery, and at the end, accuses Miho of costing her old school the championship by abandoning the flag tank.
** Erika is a {{Jerkass}} in the anime, but mainly to the extent of being snide and condescending toward Miho (for example, in the finals, saying that Oarai must be weak if she became its commander). In the manga, between the semifinals and the finals, Erika flies over to Oarai, confronts Miho, and angrily accuses her of not just costing them the victory, but abandoning them in their time of crisis, and vaguely insinuates that Miho traded her vice-captaincy of her old school for captaincy of her new school. She's significantly more vicious and angry in that scene from the manga, and leaves Miho in tears at the end of it.
* ''Manga/{{InuYasha}}'': Izumo/Gyu-oh of episodes 94 and 95. The English dub of those episodes makes him a full-fledged villain, whereas the original Japanese made it clear that he was a TragicMonster who was just driven by his madness.
* Ho Yinsen in the ''Anime/IronMan'' anime. Though near the end it turns out he's technically BrainwashedAndCrazy.
* ''Anime/TheJungleBook'':
** In the original story, the first of the tigers unintentionally brought disaster to the jungle, but he initially wanted to kill Fear (man) to restore peace among the animals, then later out of grief for finding that all those who once looked up to him would now run away in terror. In the anime, he simply believed that killing Fear would grant him supreme power over all. The Arabic dub has the tiger attempting to frame a man for a murder he himself committed; not as aspiring a goal as the former but no less despicable.
** The human owner that cared for Bagheera when he was a kitten. In the novel, Bagheera was part of a collection of exotic animals belonging to a rich rajah where he lived in luxury before escaping on his own. In the anime, the owner planned to kill Bagheera for his pelt when he grew bigger as he abused the panther along the way, the owner's daughter named Linda took care of him at that time. Later she frees Bagheera before her father can shoot him. She took the bullet, and it was unknown is she survived or not.
* The [[Literature/AliceInWonderland Cheshire Cat]] in the manga adaptation of the ''Franchise/KingdomHearts'' series is outright villainous, compared to his more neutral role in his origin book and in the game. Maleficent even offered him a place in her group, but he declined.
** He's at his worst in the manga adaptation for ''Manga/KingdomHearts358DaysOver2'': Roxas wished to be let out of a cage he was imprisoned in for trespassing the White Rabbit's house and pretending to be his servant, Mary Ann. The Cheshire Cat granted his wish by [[JackassGenie throwing a hedgehog at the Queen of Hearts]] and [[MoralEventHorizon framing Roxas for the crime]], causing her to order the young Nobody's execution by [[OffWithHisHead guillotine]].
* To a lesser extent, King Dedede of ''Anime/KirbyOfTheStars'' (pictured). While he still rarely exceeds the petty comedic {{Jerkass}} of [[VideoGame/{{Kirby}} the original games]], the SliceOfLife nature of the anime means his anime counterpart gets far fewer [[PetTheDog benevolent moments]] and he usually plays the main antagonist of each episode. In the games, King Dedede will often [[RivalsTeamUp put his rivalry with Kirby aside]] when faced with a truly [[KnightOfCerebus dangerous]] villain, and join forces with him to defeat it. In ''VideoGame/KirbyTripleDeluxe'', he even [[BigDamnHeroes saves Kirby from the villain]] with no prompting after Kirby frees him of his [[DemonicPossession possession]].
* ''Manga/TheLegendOfZelda''
** In ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina Of Time]]'', Sheik is helping Link in his quest to defeat Ganondorf. In the manga adaptation, he's soon revealed to be [[TheMole secretly working for Ganondorf]]. [[spoiler:This is subverted as, just like the game, Sheik is actually Zelda and a DoubleReverseQuadrupleAgent]].
** The Happy Mask Salesman from ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]'' gives the player some creepy vibes but genuinely wants to retreve the titular mask before it destroys Termina. In the manga adaptation he's heavily implied to be behind the events of the story.
* ''Manga/MagiLabyrinthOfMagic'': While Fatima is a ruthless slave trader in both the anime ''and'' the manga, both of which show him choosing to feed an IllGirl potential slave to a pack of hyenas rather than simply give her medical treatment because it's "not worth the money," the manga also shows that he himself was once a slave who was broken down and made loyal to his mistress Umm Madaura, who, among other things, sold him as a SexSlave to a male client. The anime completely edits out his rather horrific backstory, making him an utterly unsympathetic {{Jerkass}}.
* In the ''Manga/MaiHime'' manga, the main antagonists of the first arc are Haruka and Yukino, the latter of whom is friends with Mai and Mikoto in the anime, and the otherwise heroic Akira assists them. By contrast, Shizuru never turns PsychoLesbian, and Nao ([[TeethClenchedTeamwork reluctantly]]) helps the heroes after the teams merge.
* In the ''Manga/MaiOtome'' manga, Tomoe is DemotedToExtra and does not attempt to plot against Arika, and Nina never does a FaceHeelTurn. On the opposite end, Sergey goes from a PunchClockVillain who betrays the BigBad for his daughter's sake to a BigBad who is not related to Nina, biologically or otherwise.
* Char Aznable from the original ''Anime/MobileSuitGundam'' and its sequels certainly had his faults (up to and including [[Anime/MobileSuitGundamCharsCounterattack that time he tried to blow up the Earth]]), but ''Manga/MobileSuitGundamTheOrigin'' manages to up the ante even further by making him a freakin' ''[[RapeIsASpecialKindOfEvil rapist]]''.
** Really, all of the Zeon figures except [[AntiVillain Ramba Ral]] are shown to be much more vile and cruel in ''Origin''. Ramba's biological father and Char's mentor, Jimba Ral, was vaguely described as a loving father figure in the original anime. In ''Origin'', Jimba is a borderline ConspiracyTheorist and AbusiveParent who may have shaped Char into a sociopathic TykeBomb. Likewise, Kycillia Zabi was originally portrayed as a stoic Chessmaster who acts out of loyalty to her family. Here, she is shown to be a [[BloodKnight violence-loving]] ManipulativeBitch who happily backstabs her own family members [[LackOfEmpathy without a care in the world]]. Even Garma and Dolze were given more KickTheDog moments though they are still considered the nicer Zabis.
** Rather than making Garma a villain, ''Origin'' takes away his positive traits. In the anime he was shown to be a good person in general, being AFatherToHisMen, having a fiancée who loved him, was legitimately friends with Char (hence his shock when Char betrays him), and wants very much to prove that he deserves his command post and didn't just get promoted because [[{{Nepotism}} his father is Zeon's leader]]. In ''Origin'', he's the exact opposite of all this: a whiny SpoiledBrat who got jealous over Char's promotion, threw a literal stompy-foot temper tantrum to Daddy, got promoted (mainly because Degwin wanted him to shut up), and immediately went to Char to brag; on top of that, once he's in command he hurls [[WeHaveReserves wave after wave of his men into battle]] to earn himself glory.
* Kushana in the ''Manga/NausicaaOfTheValleyOfTheWind'' manga is introduced as an antagonist, but it's more a case of her goals not aligning with the protagonists, and when circumstances change she ends up [[HeelFaceTurn an ally to Nausicaä]]. In TheMovie, she's the main villain.
* ''Anime/NeonGenesisEvangelion'':
** Gendo Ikari: In the anime, he is AmbiguouslyEvil, he sincerely praises Shinji for his combat performance at one occasion, and with his FamousLastWords he regrets having been a bad father to him. In the manga adaptation, he is unquestionably evil, has a [[GodIsEvil massive]] [[AGodAmI God-complex]], and outright hates Shinji. In the manga, he's also implied to have [[spoiler: personally killed Kaji]], whereas it was unknown if he had anything to do with it in the anime, even though he was hinted at being involved somehow. He's somehow even ''worse'' in ''Manga/NeonGenesisEvangelionCampusApocalypse''.
** To a smaller extent, Kaworu. In the original anime, he was pretty nice (outside of, you know, [[spoiler:being the seventeenth Angel]]). In the manga, he [[KickTheDog strangles an abandoned kitten]] (a scene infamous enough to earn him the nickname [[FanNickname "Evil Manga Kaworu"]]) and has a much stronger case of BlueAndOrangeMorality.
* ''Anime/{{Pokemon}}'':
** A few Gym Leaders aren't as nice as their game counterparts. CreepyGood Sabrina is converted into something of a demonic witch who antagonizes Ash and co., while many others, most notably Lt. Surge, Erika, and Skyla, are egotistical {{Jerkass}}es with a condescending demeanor towards their challengers (or, in Erika's case, towards those who don't appreciate the perfume her gym makes). Pryce is a JerkWithAHeartOfGold who is cold towards Pokémon due to a misunderstanding with his Piloswine long ago, although he ''does'' get better when the Piloswine is found and the situation explained. In particular, Sabrina in the games is implied to be a good-natured person who happens to have [[CreepyGood frightening powers]], Pryce is a perfectly pleasant and decent man, and Lt. Surge, while cocky in the games, isn't nearly as mean about it as he is in the anime. All of them [[DefeatEqualsFriendship make friends with the heroes]] in the end. However, others, like Brock, Misty, Cilan, Iris, and Clemont, join Ash as protagonists and are more openly heroic characters.
** Ocasionally used with the Pokémon themselves (particularly either [[PoisonIsEvil Poison]] or [[DarkIsEvil Dark]] types). In the games and the anime itself, even Pokémon seen working for the antagonists generally aren't actually evil, [[PunchClockVillain just taking orders from their trainers]], and aggressive wild Pokémon are only animals obeying their instincts. While genuinely evil Pokémon do exist in the anime (such as a group of Malamar in ''XY'' and an unusually mean Togepi in ''Diamond and Pearl''), they are a minority and not representative of their species as a whole.
** Giovanni was the head of a {{yakuza}} in the games but made a HeelFaceTurn after being defeated by Red and disbanded Team Rocket (though ''[[VideoGame/PokemonGoldAndSilver HeartGold/SoulSilver]]'' implies he intended to grow stronger and one day rebuild it). Giovanni in the anime never disbanded Team Rocket and is far more violent and cruel than his game version is portrayed.
** Team Galactic is hit by this. They're a good deal more sinister and self-interested than they were in [[VideoGame/PokemonDiamondAndPearl the games]]. Cyrus in particular becomes a lot more malevolent, with his altruistic acts and qualities removed, and his tragic backstory never brought up. Moreover, he resorts to methods far worse than anything he did in the games.
** In ''VideoGame/PokemonBlack2AndWhite2'', Colress, while still a scientist in the employ of Team Plasma, does [[FriendlyEnemy encourage]] the player and even gives them a device needed to progress further in the game. He is involved with Team Plasma ForScience and is not particularly interested in their goals, expressing distaste for Ghetsis. After his defeat, he encourages the player to stop Ghetsis' plans. In ''Episode N'', Colress is a true MadScientist who experiments on Pokémon to the point of torture, uses mind control on the Pokémon in his introductory episode (including those of the main characters), and is more than willing to hurt Ash and his friends to prove his theories. He is also more appreciative of Ghetsis due to Plasma's "providing" increasingly more difficult "subjects" pushing the theories further. Colress in the game has a HeelFaceTurn, willingly disbands Team Plasma, and becomes TheAtoner after Ghetsis is defeated (which [[spoiler: his cameo in ''VideoGame/PokemonSunAndMoon'' follows through on]]), while his anime counterpart is arrested by Looker. The anime counterpart does come up with the idea for a [[SpeaksFluentAnimal Pokémon translator]], but after he's arrested and in a way emphasising his BlueAndOrangeMorality.
** Team Plasma as a whole is subject to this in ''Episode N''. While not a pleasant group in the games, Plasma is often engaged in moral debates about their intentions under Ghetsis, sometimes questioning their motives, and [[VideoGame/PokemonBlack2AndWhite2 eventually splitting into two factions]]: one genuinely concerned for Pokémon wellbeing and N's ideals, and the other being more self-centered and devoted to Ghetsis. In the anime; Plasma are outright villains with none of the moral conflicts they have in the games, fully supportive of Ghetsis' goals and [[VileVillainSaccharineShow posing a]] [[KnightOfCerebus very large threat]] to Ash and his friends throughout their arc. Uniquely, this was deliberate by the writers as their initial appearance ended up being [[TooSoon indefinitely postponed by the 2011 Tohoku earthquake and tsunami]].
** In ''[[Anime/PokemonArceusAndTheJewelOfLife Arceus and the Jewel of Life]]'', while Marcus attempts to [[KillTheGod betray and kill Arceus]] using extremely heinous methods which have serious consequences in the future, he seems to genuinely believe that returning the Jewel of Life to Arceus will cause Michina Town to turn back into a wasteland and that his actions are necessary to prevent this. [[spoiler: As it turns out, this is the case, but the inhabitants are able to restore the valley on their own.]] In the tie-in manga, his motivations are purely selfish -- he wants to kill Arceus [[AGodAmI to become a god himself]].
** In ''VideoGame/PokemonXAndY'', Yveltal, despite being the Destruction Pokémon, teams up with the player to stop Team Flare's genocidal plans, just as its life-giving counterpart Xerneas does. In addition, its destruction powers are only referred to in the context of being part of its lifecycle. In ''Anime/PokemonDiancieAndTheCocoonOfDestruction'', it is the BigBad of the movie who seems to take joy from deliberately sucking the life out of everything around it, and is more clearly a DarkIsEvil foil to the LightIsGood Xerneas.
** In the games, Mimikyu is a mischevious but DarkIsNotEvil Pokémon who imitates Pikachu because it's lonely and just wants to be loved like Pikachu. In the anime, the first Mimikyu seen is much more bitter and jealous towards Pikachu to the point of being an EvilCounterpart, even going so far as to willingly join Team Rocket. Downplayed, since other Mimikyu may have a more friendly personality.
** The Spearow line in the anime are, with one or two exceptions, generally owned by villains or are malicious of their own accord, to the point of holding grudges (most famously against Ash in the first episode and the incident which led to Pidgeot's evolution). In the games, there's nothing to indicate this level of malice - while a wild Spearow flock attacks Nebby in Sun/Moon, many other Spearow and Fearow are seen living and working with people, even as affectionate house pets, with no problem, and their Pokedex entries don't portray them in a negative light compared to other bird Pokémon.
** Team Flare in the ''XY and Z'' arc are more sinister and dangerous than their game iterations. In particular, Lysandre's history with Professor Sycamore and his backstory in the games as the descendant of AZ's brother and a FallenHero are not touched on, and in the games Xerosic eventually pulls a postgame HeelFaceTurn under the influence of [[MoralityPet Emma]], a girl who befriends him. Lysandre is more than willing to lay waste to Lumiose City to accomplish his goals in the Team Flare Crisis arc; and Xerosic is not above [[WouldHurtAChild harming Clemont]] for the sake of science in his appearances, with him seeking vengeance against him for stopping his plans at Prism Tower.
* ''Manga/PokemonAdventures'':
** Some of the Gym Leaders and Elite Four members. While most of them (with the exception of Giovanni and Malva) are good guys in the games -- Lance and Lorelei even helping out the player character at key points -- Lt. Surge, Koga, Sabrina, Agatha, Bruno, Lorelei, Lance, Karen, Will and [[spoiler: Pryce]] are villains. [[spoiler:To be fair, though, Pryce is a more sympathetic AntiVillain, Lance is a WellIntentionedExtremist, and most of the other characters listed [[HeelFaceTurn reform]] later on, with the exception of Agatha.]]
** In the games, Norman is a kind, gentle person who respects his child's wishes and would most likely not use physical violence. In the manga, Norman is a lot meaner and beats up his son for disobeying him. Despite his harshness, though, he is on the side of good and is genuinely supportive of Ruby.
** In ''VideoGame/PokemonRubyAndSapphire'', Archie and/or Maxie are ObliviouslyEvil [[WellIntentionedExtremist Well-Intentioned Extremists]], and they are probably the least evil villainous team leaders in terms of [[BenevolentBoss concern for their subordinates]] and sincere, if misguided, intentions as opposed to more manipulative and darker characters like Cyrus, Ghetsis, and Lysandre. Both of them have a HeelRealization once they [[MyGodWhatHaveIDone see the true effects of their plans]] and quickly HeelFaceTurn. This characterization is followed up in the anime and in the remakes. In ''Adventures'', neither one reforms -- they go into SanitySlippage and [[spoiler:are both seemingly KilledOffForReal]]. Maxie even [[spoiler:outright ''kills'' Norman (although he [[CosmicRetcon gets better]])]]. [[spoiler: However, both return and ultimately redeem themselves in the later ''Omega Ruby and Alpha Sapphire'' chapters, assisting the protagonists in saving the world.]]
** In ''VideoGame/PokemonBlackAndWhite'', N is a very sympathetic AntiVillain with good intentions. He eventually makes a HeelFaceTurn in the sequel games, helping the player against Ghetsis, his much more evil adoptive father. However, N has fewer redeeming qualities here and manages to convince White's Tepig to leave her. His goal also seems to be more like Ghetsis' goal than in the games.
** The manga's version of Colress is portrayed along the same lines as in the anime; being a more wicked MadScientist than his morally grey game counterpart.
** Team Flare in the games are largely an IneffectualSympatheticVillain team in the vein of early Team Rocket, [[spoiler:with the exception of BigBad Lysandre]]. In the ''XY'' arc, Team Flare ends up having their more malicious elements increased and their campier ones suppressed, [[spoiler:to the point of burning Vaniville Town to the ground in order to obtain X's Key Stone and Kanghaskhanite]].
* ''Anime/PokemonGenerations'':
** The Old Chateau ghosts and Rotom were creepy, but ultimately made little to no effort to harm the player in ''VideoGame/PokemonDiamondAndPearl''. This iteration of them, however, are much more sinister and openly terrify Cheryl.
** Boy, [[RuleOfThree Colress just has no luck in adaptations]], huh? This version, while closer to the original in terms of motives, is still outright villainous as he is completely apathetic both to Kyurem's suffering and to the entire population of Opelucid City, whom he decides to test the dragon's power on.
* ''Manga/{{Pretear}}'': In the manga version, one of the Leafe Knights ([[spoiler: Sasame, the Knight of Sound]]) is strongly hinted to have been in love with the villain in the backstory, but he's definitively a good guy and remains that way for the entire story. In the anime, where Fenrir plays a bigger role, he eventually breaks down and becomes her minion because of his MadLove.
* ''Franchise/SailorMoon'':
** Queen Beryl was a villain in [[Manga/SailorMoon the manga]], but an ultimately tragic figure who was manipulated by Metaria into her crimes in her past and current incarnations, and ultimately doomed not by her villainy, but her own belief that she was beyond redemption at this point. In TheNineties [[Anime/SailorMoon anime]], she's a straight-up evil villain who willingly and loyally serves Metalia.
** Although this is more of a case of Adaptational [[AntiHero Anti-Heroism]], Rei Hino[=/=]Sailor Mars is hit with this in the 90s anime. Rei seems more abusive towards her friends (especially to Usagi) in the anime than in the manga, especially in the first season. It's even worse in the DiC dub where Rei (or Raye as she is called in that dub) makes no qualms about wanting to kick Serena out of the Sailor Scouts and take over as the leader.
* Kaede Fuyou from ''VisualNovel/{{Shuffle}}''. While ''not'' exactly a villainess, she did, in both versions, believe that Rin was responsible for her mother's death (a misconception he encouraged to prevent her from losing the will to live), and abused him for years until learning the truth, at which point she devoted herself to him in order to atone. In the anime, in which Rin canonically goes out with their mutual friend and [[SenpaiKohai senpai]], Asa, resulting in him spending less time with Kaede (in part not wanting her to be consumed with him), she snaps and attacks Asa, causing her to collapse, but comes to regret this later. In the visual novel, after finding out that Rin and Asa are a couple, Asa apologizes, but Kaede sadly accepts their relationship, albeit with the scene being somewhat similar to Kaede and Asa's reconciliation from the anime.
* Shadow the Hedgehog in the ''Anime/SonicX'' anime. In the games, Shadow started off a vengeful weapon ready to destroy Earth's population in honor of his murdered friend. Throughout his story however, he is portrayed with a palpable sense of doubt and emotional conflict, before ultimately pulling a full HeelFaceTurn two games later. In the anime, he roughly follows his games counterpart's story, but maintains his more sinister neutral alliance and is TheUnfettered to the highest scale (at least once perfectly willing to kill a child in cold blood, along with anyone who defended her, if it meant stopping a villain).
* ''Manga/SoulEater'':
** [[MadScientist Dr. Stein]] . In the manga, he's [[SociopathicHero semi-sociopathic]], [[TheCorruptible prone to insanity]], and [[AxCrazy rather disturbing even when he's sane-ish.]] However, he's still good throughout, [[spoiler: even when Medusa begins artificially enhancing his madness]], and clearly cares about his students and teammates. In the anime, however, [[spoiler: he temporarily goes over to Medusa's side and even attacks [[MoralityChain Marie.]]]]
** [[spoiler: Justin Law]] is an [[AdaptationalHeroism inversion]]: he is revealed as TheMole and is [[spoiler: BJ's killer]] in the manga, whereas he stays firmly on the side of good in the anime.
* In ''Anime/TenchiMuyo'', Princess Ayeka is a quite haughty figure who ends up coming back down to Earth as she spends time with Tenchi and while there's a rivalry with the space pirate Ryoko, the two do have something of a friendly relationship as time goes on. While ''Anime/TenchiUniverse'' and ''Anime/TenchiInTokyo'' tends to ramp up these aspects, ''Anime/PrettySammy'' ends up turning her into an AlphaBitch flanked by her own entourage and willing to hunt down Ryoko just because she's with Tenchi. It gets worse in ''Magical Project S'' as Ayeka is recast as a third goddess who was removed from the election to become protector of Earth and she seeks to destroy Earth because of it.
* ''Anime/VariableGeo'' does this with [[LipstickLesbian Ayako's]] character. In [[VideoGame/AdvancedVariableGeo the game series]] which the OVA is based on, she protects women by luring out would-be muggers and rapist and brining them to justice. By contrast, the anime [[DepravedHomosexual practically makes Ayako a rapist, herself]], by having her sexually harass Satomi during their fight. She not only shreds Satomi's uniform, using [[CombatHandFan a hidden blade]], she even gropes Satomi and pecks her on the cheek. For Satomi, ''[[RageBreakingPoint that]]'' [[KillItWithFire was the last straw.]]
* Thanks to the ''Manga/VenusVersusVirus'' anime [[OvertookTheManga coming out]] while the manga was still ongoing it has a different plot and a GeckoEnding. [[spoiler:Lucia's father Lucif]] is the BigBad of the anime but is a far more neutral character in the manga.
* In the ''Anime/TheVisionOfEscaflowne'' movie, Folken is a psychotic BigBad, while in the original series he was more of an AntiVillain or a DragonWithAnAgenda to the actual BigBad, Emperor Dornkirk (who is absent from the movie altogether), with some good qualities such as [[BenevolentBoss respect for his subordinates]], [[EqualOpportunityEvil including races which suffer from]] FantasticRacism. [[spoiler: In fact, in the series he eventually has a HeelFaceTurn.]]
* This occurs in-series in ''Anime/YokaiWatch''. When Komasan reveals to a mangaka that he is really a {{yokai}} she uses him as inspiration for her manga. Sadly it is a horror manga where he is a big, scary monster instead of the cute CartoonCreature he really is.
* ''LightNovel/YoujoSenki'': Tanya Degurechaff, and the HR manager she reincarnated from, become more callous and heartless with each adaptation. In the first scene alone, the light novel depicts the HR manager as doing everything to help salvage the career of the employee he would fire, but said employee is a belligerent drug addict. In the manga, he is stated to not enjoy firing his employees, but has a quota to meet to keep his company aloft, and the employee he is firing is perpetually tardy or absent and a drain on company morale due to his poor work ethic. In the anime, he is shown as selfish and only interested in advancing his own career, and thus has no qualms in firing anyone who would be an obstacle in his upward mobility in the company.
* ''Franchise/YuGiOh''
** In the original ''Manga/YuGiOh'' manga, Rex Raptor/Dinosaur Ryuzaki, while a bit of a jerk, doesn't cheat and he did have a more helpful and honorable side. The [[Anime/YuGiOh anime's]] version of Rex is closer to the manga version's characterization at first, but eventually associates with more villainous characters like Dartz and Weevil Underwood in a way that Manga Rex never did, and he eventually tries to steal Joey's soul.
** Bonz/Ghost Kozuka in the manga is a PunchClockVillain working with Bandit Keith, feeling that Keith trapping Yugi, Joey and the others in a cave to get them out of the Duelist Kingdom tournament was going overboard and getting an AlasPoorVillain death when he ends up having the misfortune to duel Yami Bakura in the Battle City tournament. In the anime Bonz has no problems with Keith trapping the others in the cave and tries to cheat by stealing everyone else's duel cards during the Battle City arc, turning him into an AssholeVictim when Bakura runs across him.
* ''Anime/YuGiOhGX'':
** In both the original and dub version, Daitokuji-sensei is an AntiVillain using a façade to hide his true intentions, but the façade is much, ''much'' nastier in the dub. While in the original he spends his duel with Judai giving a NotSoDifferent speech in which he compares Judai's Fusion Monsters with the ancient practice of alchemy, in the dub he goads Judai and tells BlatantLies about his previous victories at the Academy being the result of rigged duels. (Which he admits was untrue after losing.)
** Chosaku Manjoume, or Slade Princeton in the dub has a minor case of this. In the original japanese version, after he loses to Jun (Chazz in the dub), he tells Shoji/Jagger that their little brother has grown up more than they thought and grows respect for him. None of this occurs in the dub, and he's more annoyed that he lost if anything.
** The Dark World Fiends were presented as villains in the third season, which contradicts the flavor text of some of their cards in the game and the ''Master Guide 2'', which claims they are not evil. In fact, the flavor text on [[http://yugioh.wikia.com/wiki/Zure,_Knight_of_Dark_World Zure, Knight of Dark World's]] card claims that he "never oppresses the commoners", while that's probably what he's most notorious for doing in the anime.
** Also, in the manga version, Jim Cook is an antagonist who is far more malicious than his lighthearted and benign anime counterpart. [[spoiler:It's not his fault, however; he's a BrainwashedAndCrazy pawn of [[BigBad Tragoedia]].]]
** Like Daitokuji-sensei above, Yubel also got subjected to this in the dub. While she was still a terrifying villain in the original with ''many'' horrible deeds under her belt, she was ultimately motivated by [[LoveMakesYouEvil her love for Juudai]] [[LoveMakesYouCrazy and her desire for him to]] [[ForgottenChildhoodFriend remember her]]. The dub turned her into a straight-up psychopath who wanted to "[[BreakTheCutie play]]" with him, and because it cut out Season 4, she never had her HeelFaceTurn.
* In the manga version of ''Anime/YuGiOh5Ds'', pretty much every character has a different background and personality, but Rua and Ruka more so than any other. They start of as villains in this version (and rather sadistic ones at that) ''very'' unlike the kind and innocent children they are in the anime. It is later revealed that [[spoiler:Rua underwent a [[DealWithTheDevil Duel Dragon ceremony]] to save Ruka from an illness, only Luna to become enslaved by the spirit of one of the Duel Dragons and for Rua to become {{Brainwashed}} by ''her''. Eventually, Yusei is able to use his more benevolent Dragon to break the spell.]]
* ''Anime/YuGiOhArcV'':
** As the series is all about [[spoiler: AlternateUniverse versions of the previous series]], this shows up more with cultures and societies than it does with individual characters. The forefront example is [[spoiler: Duel Academia]], which basically took the [[spoiler: Duel Academy from ''Anime/YuGiOhGX'']] and turned it from an AcademyOfAdventure that trains kids to be skilled duelists into an AcademyOfEvil that trains kids to be merciless ChildSoldiers [[spoiler: [[WarForFunAndProfit who commit genocide for fun]]]] and act as [[BigBad The Professor's]] personal army. In regards to members (and former members) of the school, folks like Asuka still have morals (she defected after they started using Human Sealing Technology), but are [[GoodIsNotNice still darker than previous versions.]]
** [[spoiler: The Synchro dimension]] is modeled on the situation in [[spoiler: ''Anime/YuGiOh5Ds'']], but the counterparts for [[spoiler: Neo-Domino and Satellite]], the Tops and the Commons respectively, are both worse than the originals. The Tops instigated the economic inequality themselves and are proportionally a much smaller group than their original versions (they make up 1% of the population, whereas the populations of [[spoiler: Neo-Domino and Satellite]] were implied to be more even). The Commons buy into the BreadAndCircuses act so thoroughly they not only support the worst aspects of their world, [[spoiler: they insult and mock Yuya for speaking out against institutionalized slavery]].
