History HeelFaceTurn / AnimeAndManga

** Several villains experience this as well to varying degrees. Buggy, while still evil, became more caring for his crew after his defeat. Hatchan (one of Arlong's subordinates), Bon Clay, and Mister 3 (of Baroque Works) all showed up again much later to become an ally of the Straw Hats; even the arrogant leader of Baroque Works, Crocodile eventually allies himself to Luffy in his escape from Impel Down, and though dismissing it simply as [[EnemyMine something he's doing because his own convenience]], he ends going out of his way to save Luffy from a certain death in the battle of Marineford. Notably, [[PsychoForHire CP9]] defects from the World Government after their defeat…but in all likelihood, they turned from Heels to [[WildCard Wild Cards]].

* ''Manga/DragonBall'' and ''Anime/DragonBallZ'' practically built its cast this way. By the end of the series, most of the heroes are former villains; it's easier to list the characters who didn't try to kill or at least beat Goku up when they met him than otherwise. For that matter, Goku himself had a {{backstory}} heel-face turn, when his inherent Saiyan nature was subverted by a blow to the head. It took Vegeta the longest to fully turn, and he actually turned all the way back to [[FaceHeelTurn heel]] right before it happened.
** To highlight it better, of the core cast of Z fighters from throughout DBZ, Goku himself had been sent to Earth initially to depopulate it as a mindless ape, Yamcha was a bandit who tried to rob Goku when they met, Krillin was TheRival for Master Roshi's attention, Tien and Chaozu were students of the Crane Hermit, a wicked rival to Master Roshi, Piccolo was the son/reincarnation of EvilOverlord King Piccolo out to avenge his father/former self's defeat by Goku, Vegeta came to Earth solely to steal the Dragon Balls and kill anyone who got in his way, Androids 17 and 18 were rebellious punks who caused a BadFuture in Future Trunks' timeline, and Majin Buu was a childlike pink blob monster who didn't even realize that causing death and destruction was bad until Mr. Satan set him straight.

** And now we have to add [[spoiler:[[Anime/GoPrincessPrettyCure Princess Twilight]] (Prince Kanata's sister Towa) to the mix, as she's been cleansed from Dyspear's evil brainwashing and is now Cure Scarlet.]]

* Sasame in ''{{Pretear}}'' after his earlier FaceHeelTurn is seen in the end happily living with Takako. Takako also decides she's had enough and switches sides in the end, it doesn't help much because she's still used by the BigBad Tree of Fenrir but can't hate her for trying.
* Effective in both the SoulEater anime and manga with [[spoiler: Crona]], though the way it plays out is rather... different.

** In Chapter 627, [[spoiler:The Greatest example of this trope in Naruto has occurred. That's right people, Uchiha Sasuke has decided to ally with the good guys.]] but it turns out that while Sasuke has decided to do this and even to [[spoiler:become Hokage]] The pep talk he got from Hashirama only turned him into a WellintentionedExtremist.He wants to kill anyone who he considers an obstacle to his Revolution. This includes [[spoiler:Naruto and all of the Kage.]].

* Happens frequently in ''{{Slayers}}'' though they are more [[CharacterDevelopment Hazy-Feel Turns]], most foes being ChaoticNeutral mostly:

* Bad Bird in ''SamuraiPizzaCats'' who joins up with the good guys after a speech from Speedy saying that if Bad Bird helps Cheese win, everyone in Little Tokyo dies, including Bad Bird's girlfriend.

* Subverted in the ''Manga/SoulEater'' manga -- Crona had changed sides, but comes back to the dark side at Medusa's request. And to make things worse, [[spoiler:Crona kills Medusa and now goes on collecting the Kishin eggs]]. The face turn sticks in the anime.

* In ''RaveMaster'', this happens more often than not. Julius, Shuda, Let and Lazenby all making prompt turns after losing to Haru or others. Also notable are King, Jegan and Captain Hardner, who make Heel-Face Turns [[spoiler:the exact moment before they die]]. And then there's the case of Reina, who makes a Heel Face Turn but then [[RedemptionEqualsDeath undergoes a]] HeroicSacrifice afterwards.

* Pixy Misa in ''MagicalProjectS''. Considering [[DarkMagicalGirl her concept]], it was inevitable.

* Adette Kistler from ''OvermanKingGainer'' joins the Exodus once she is forced to stay in the city units for a while. She eventually even takes command of her own group of fighters.

* In ''OutlawStar'', the evil Anten Seven's leader Hazanko sends elite assassin Shimi (a.k.a Leilong) to eliminate Gene Starwind when he is considered a threat to his plans. Gene faces a much weaker assassin and impostor of the real Shimi but barely wins. The real assassin converses with Gene in a bar as Leilong and you can tell he is thinking about making a serious change in his life while not revealing his true identity as an assassin to Gene. Later on, Leilong engages in a CurbStompBattle against Gene and his crew. Gene the last one standing of his crew agrees to a gun duel to the death which has Leilong get "killed" because of his faulty gun. Turns out the whole battle was orchestrated by the assassin to fake his own death, and to leave the Anten Seven. WordOfGod states that Shimi was actually a Dragon and his power was SECOND to Hazanko's level, so if Shimi didn't have that Heel Face Turn the Outlaw Star crew (who were much weaker at the time) would have been killed off before the hunt for the Galactic Leyline.

* ''Franchise/MagicalGirlLyricalNanoha'' [[DefeatMeansFriendship Befriends many of her enemies]]. To put it in perspective, the only returning good member of the regular cast in the third Season who didn't start out as a villain in one way or another is Nanoha herself.

* In the original English language manga ''AmazingAgentLuna'', Timothy Hyatt, upon learning Elizabeth Westbrook is to be killed, switches sides and helps her escape. He later returns to deal with his former partner, Martin Williams.

** It seems Hidan was the only major Naruto villain that never saw the light and died as a CompleteMonster.

** At this point, [[spoiler:Madara]] is the only major villain that ''hasn't'' seen the light. It remains to be seen whether that will last...
*** [[spoiler:It doesn't. He finally is brought down by an AuthorsSavingThrow and DefeatEqualsFriendship.]]

** In ''[[Anime/MagicalGirlLyricalNanohaStrikerS StrikerS]]'', seven of the twelve Numbers and [[spoiler: Agito]].

* There are several Heel and Face turns in ''Anime/GundamSeed''. Loyalties and what one fights for are driving themes for the entire series, in fact.

* In ''{{Gundam 00}}'', [[spoiler:A-LAWS members [[ColonelBadass Kati Mannequin]] and [[IneffectualSympatheticVillain Patrick Colasour]] vanished after the TimeSkip. Then they come back under the Katharon to help the Celestial Being attacking the A-LAWS, while reciting just how corrupted the A-LAWS is, the reason of their defection.]]

* At the end of ''ZettaiMutekiRaijinOh'', [[KidHero Jin's]] parents convincing the villain's {{mook}} Taida to [[MookFaceTurn switch sides]] turns out to be a CrowningMomentOfHeartwarming. Later on, Taida's boss actually follows and has a Heel Face Turn of his own.

* In ''TenshiNiNarumon'' [[spoiler: Mikael, after acting like a nice guy for the majority of the series and then turning into an evil and insane twit, does exactly this. Yes, the boy has issues]].

** And now we have to add [[spoiler:[[Anime/GoPrincessPrettyCure Princess Twilight]] (Prince Katana's sister Towa) to the mix, as she's been cleansed from Dyspear's evil brainwashing and is now Cure Scarlet.]]

* Rocket from ''GingaDensetsuWeed'' starts off as one of Hougen's spies but after about 3 episodes, he becomes one of the nicest dogs in Weed's pack.

* Lady Liebert and half of her comrades of Nepos does this midway through ''Anime/MajinBone''

* There are several Heel and Face turns in ''GundamSeed''. Loyalties and what one fights for are driving themes for the entire series, in fact.

* Char Aznable in ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]''. This [[CharsCounterattack reverses]] into a FaceHeelTurn.

** [And in chapter 667, [[spoiler: Kabuto has joined the fray, helping to revive Sasuke. The reason? His time in Itachi's Izanami spell helped Kabuto realize his true nature, that he's really a good person deep down, and that he has a home to return to.]]

* Nearly every villain in ''Kero Kero Chime''. In fact, in a bizarre and random musical sequence in the last episode, Demon King Bao, the SealedEvilInACan who turns out to be the true reason most of the Hebizoku and Kaeruzoku disappeared 10 years ago, as he took them with him upon being banished, reveals that he's completely reformed, and he and his former enemies like being Trapped In Another World, as it's allowed them to become such great friends.

** Heck, a lot of the Straw Hat Pirates' friends are formed from EnemyMine, FireForgedFriends, or DefeatMeansFriendship: the Shandorians, the Franky Family and Galley-La Company, the Rosy Life Riders, the Kuja tribe, the prisoners of Impel Down, the Whitebeard Pirates, Neptune's Army, and most recently, [[spoiler:Smoker, Tashigi, the almost AxCrazy Marines of G-5, and a pirate-hating samurai by name of Kin'emon (though he's far from the first pirate-hater that the Straw Hats befriended). Smoker and Tashigi already respected them because of the Alabasta incident; just how close they are now has yet to be revealed. But their subordinates? Much to Smoker's exasperation and Tashigi's amusement, they've stated that they'll start admiring the Straw Hats unless they act as if they're no different from other pirates.]]
