History FaceHeelTurn / WesternAnimation

** Book 4 gives us [[spoiler:no less than ''three'' Face-Heel Turns. Kuvira went from Suyin's protegée to a power-hungry dictator who claims to want to bring peace back to the Earth Kingdom but really seeks control, Baatar Jr. who followed Kuvira and took a ''massive'' level in Jerkass in the process, and Zhu Li, who pledged loyalty to Kuvira after finally getting fed up with Varrick for his poor treatment of her.]]

* A {{Flashback}} episode of ''[[WesternAnimation/ChallengeOfTheGoBots GoBots]]'' revealed that Cy-Kill was once Leader-1's best friend, but frustration over the leadership of Gobotron caused Xy-Kill to join the rebellion (and eventually lead it).

* [[WesternAnimation/MyLittlePonyFriendshipIsMagic Princess Luna's]] descent into Nightmare Moon.

* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode ''[[Recap/MyLittlePonyFriendshipIsMagicS4E25TwilightsKingdomPart1 Twilights Kingdom Part 1]]'', Discord is swayed into helping Tirek in exchange for true freedom.

* Zuko from ''WesternAnimation/AvatarTheLastAirbender'' does a beautiful FaceHeelTurn in the season 2 finale. Actually, he does a FaceHeelTurn, then a HeelFaceTurn, then another FaceHeelTurn, then a few somersaults, ending with another HeelFaceTurn. Say that three times fast. His first FaceHeelTurn came when he was 12. An innocent, well-meaning boy gets half his face burned off by his ''loving'' father. After this, he hunts Aang ruthlessly for his "honor." His second, and most exemplary FaceHeelTurn, came at the finale. After starting fresh in Ba Sing Se, Zuko has to choose between his honor and his Uncle. After a blatant "I Hate You" speech, he attacks Aang and returns home a hero, at least until his final HeelFaceTurn.

* Albedo from the ''WesternAnimation/Ben10'' franchise did this. In a flashback from when Ben was 11, he was allied with Ben and Azmuth, and was at least a respectful, decent guy at the time. From ''WesternAnimation/Ben10AlienForce'' onward however, he is a major enemy of Ben Tennyson, for he did turn evil during the TimeSkip between shows.

* Creator/HannaBarbera's Muttley CaptainErsatz as well as Series/{{Columbo}} {{Expy}} Mumbly was made a bad guy in ''{{Laff-A-Lympics}}'' and ''Yogi Bear and the Magical Flight of the Spruce Goose'' because they didn't have all the rights to ''WesternAnimation/WackyRaces'' at the time and [[TheyJustDidntCare couldn't be bothered]] to create a new character.

* Demona from ''WesternAnimation/{{Gargoyles}}''

* Zuko from ''WesternAnimation/AvatarTheLastAirbender'' does a beautiful FaceHeelTurn in the season 2 finale. Actually, he does a FaceHeelTurn, then a HeelFaceTurn, then another FaceHeelTurn, then a few somersaults, ending with another HeelFaceTurn. Say that three times fast. His first FaceHeelTurn came when he was 12. An innocent, well-meaning boy gets half his face burned off by his loving father. After this, he hunts Aang ruthlessly for his "honor." His second, and most exemplary FaceHeelTurn, came at the finale. After starting fresh in Ba Sing Se, Zuko has to choose between his honor and his Uncle. After a blatant "I Hate You" speech, he attacks Aang and returns home a hero, at least until his final HeelFaceTurn.

* ''WesternAnimation/StarWarsTheCloneWars'': [[spoiler:Captain Argyus, Slick, Pong Krell, Barriss Offee.]]

* In ''WesternAnimation/KimPossible'', TheDragon Shego used to be a superhero before becoming a villain. Various other characters have short heel turns, often for a single episode, including Ron at least twice.

** Mr. Krabs is a more permanent example, but YMMV.

* ''WesternAnimation/StarWarsTheCloneWars'': [[spoiler:Captain Argyus, Slick, Pong Krell.]]'

* General Modula did this prior to the start of ''WesternAnimation/SymBionicTitan''. He's seen as one of the good guys in the WholeEpisodeFlashback "Shadows of Youth". What made him turn was not answered.

* ''WesternAnimation/CodenameKidsNextDoor'' had an agent, Numbuh 274, who had appeared in a couple Season 1 and Season 2 episodes become a villain from Season 3 onwards after turning 13. However, it turned out that [[spoiler:he'd been working for [[ReverseMole the good side all along]]]] in the penultimate episode of the show.
** The 4th grade class president also began as a heroic character but, after the KND works to ensure his safe election, it's revealed that he's [[NiceJobBreakingItHero actually their enemy]]. The exact nature of his FaceHeelTurn is something of a mystery: while his blank eyes, CreepyMonotone and Father's EvilLaughter during his FaceHeelTurn implies that he'd been brainwashed, later episodes establish him as not only a [[NotBrainwashed perfectly willing]] heel, but one whose agenda has little connection to Father.

* A {{Flashback}} episode of ''[[WesternAnimation/ChallengeOfTheGoBots GoBots]]'' revealed that Cy-Kill was once Leader-1's best friend, but frustration over the leadership of Gobatron caused him to join the rebellion (and eventually lead it).
* In ''WesternAnimation/KimPossible'' TheDragon Shego used to be a superhero before becoming a villain. Various other characters have short, often for a single episode heel turns, including Ron at least twice.
** Most due to the Attitudinator, a HeelFaceTurn[=/=]FaceHeelTurn [[AppliedPhlebotinum in a helmet]]. One episode with it caused a HeelFaceRevolvingDoor for everyone but Kim Possible.

** One could argue Gene made his original turn at the start of the series, when he threw down his stepfather and took the role of Mandarin for himself. Outing himself to his friends after they out themselves as Team Iron Man just sealed the deal.

** Denahi in ''Disney/BrotherBear'' after he thinks a bear killed his brother Kenai (in reality, his brother Kenai was ''[[KarmicTransformation turned]]'' [[BalefulPolymorph into a bear]]). He spends most of the film on a RoaringRampageOfRevenge trying to kill Bear!Kenai until the very end where Kenai is transformed back right before his eyes.

* ''WesternAnimation/GreenLanternTheAnimatedSeries'': This happens to Aya after she shuts down her emotions and takes over the Anti-Monitor's body, becoming a KnightTemplar bent on eliminating all organic life to the point that she goes back in time to rewrite the creation of the universe. She comes to her senses when she accidentally nearly kills Razer.

* ''WesternAnimation/GreenLanternTheAnimatedSeries'': This happens to [[spoiler: Aya]] after [[spoiler:she shuts down her emotions and takes over the Anti-Monitor's body.]] Whether this is permanent is yet to be seen.

** Perhaps one of the more tragic examples is Copper from ''TheFoxAndTheHound'' turning into a full-on hunting dog, [[AntiVillain while still being a nice person at heart]] and [[WeUsedToBeFriends not wanting to kill his former friend]] Tod the fox. So to say, Copper does not become evil, but he's permanently switched to the side of his spiteful old hunting master, which puts him opposite of Tod, left to fulfill the traditional protagonist role.

* General Modula did this prior to the start of ''WesternAnimation/{{Sym-Bionic Titan}}''. He's seen as one of the good guys in the WholeEpisodeFlashback "Shadows of Youth". What made him turn was not answered.

** In ''TheAristocats'', we get to see Edgar turn into a villain the minute he realizes he can get all of his madam's wealth if he gets rid of her cats.

** Denahi in ''BrotherBear'' after he thinks a bear killed his brother Kenai (in reality, his brother Kenai was ''[[KarmicTransformation turned]]'' [[BalefulPolymorph into a bear]]). He spends most of the film on a RoaringRampageOfRevenge trying to kill Bear!Kenai until the very end where Kenai is transformed back right before his eyes.

* ''WesternAnimation/GreenLanternTheAnimatedSeries'': This happens to [[spoiler: Aya]] after [[spoiler: Razer rejects her and she shuts down her emotions.]] Whether this is permanent is yet to be seen.

* ''WesternAnimation/{{GreenLanternTheAnimatedSeries}}'': This happens to [[spoiler: Aya]] after [[spoiler: Razer rejects her and she shuts down her emotions.]] Whether this is permanent is yet to be seen.

* Zuko from ''WesternAnimation/AvatarTheLastAirbender'' does a beautiful FaceHeelTurn in the season 2 finale. Actually, he does a FaceHeelTurn, then a HeelFaceTurn, then another FaceHeelTurn, then a few somersaults, ending with another HeelFaceTurn. Say that three times fast.

After a blatant "I Hate You" speech, he attacks Aang and returns home a hero, at least until his final HeelFaceTurn.

* In ''{{Metalocalypse}}'', when Toki gets fed up with always being the child friendly one and then starts burning the lair with a flamethrower.

* ''CodenameKidsNextDoor'' had an agent, Numbuh 274, who had appeared in a couple Season 1 and Season 2 episodes become a villain from Season 3 onwards after turning 13. However, it turned out that [[spoiler: he'd been working for [[ReverseMole the good side all along]]]] in the penultimate episode of the show.

* [[spoiler:Raimundo]] in the season one finale of ''WesternAnimation/XiaolinShowdown''. Shortly into season two, he [[HeelFaceTurn reverses it]] and returns to his friends, but not without suffering some consequences and trust issues.
** [[spoiler:Omi]] undergoes an involuntary turn after coming back from the yin/yang dimension, leaving his good side behind.

* Dinobot in the ''{{Transformers}}: WesternAnimation/BeastWars'' episode "Maximal No More." He does a HeelFaceTurn back at the end, though, upon realizing that just because everything's going according to Megatron's plans doesn't mean that Megatron isn't a dangerous madman.
** Blackarachnia in ''TransformersAnimated'' pulls her FaceHeelTurn during the (mainly) flashback episode "Along Came A Spider." We discover that when they were in the Autobot Academy, Elita-1, Sentinel, and Optimus went to an organic planet, even though it was forbidden, and they encountered giant spiders. Escaping from the spiders, Elita used her download power to borrow Optimus's grapplers, but ran out of time, falling into a pit full of the spiders when Optimus failed to catch her with his other grappler. She attempted to use her download power on the spiders, but, the spiders being organic, it turned her into a mutated part-organic, part-mechanical Transformer with one of the spiders as her alt-mode. The new signal type made her impossible for Optimus to pick up on his radar, and led him and Sentinel to believe Elita was dead, and Blackarachnia to believe they abandoned her, and she joined the Decepticons.
** Why hasn't anyone mentioned Wheeljack from ''TransformersArmada''? He has one after believing that Hot Shot abandoned him and turns Decepticon.
** Back to ''Beast Wars'', there is also [[spoiler: Rhinox/Tankor]] in the sequel show ''WesternAnimation/BeastMachines''.

* In ''KimPossible'' TheDragon Shego used to be a superhero before becoming a villain. Various other characters have short, often for a single episode heel turns, including Ron at least twice.

* Professor Hamilton, a longtime Superman supporter, as seen in ''WesternAnimation/SupermanTheAnimatedSeries'', turns against him in ''[[JusticeLeague Justice League Unlimited]]''
* In ''IronManArmoredAdventures'', Gene Khan does this in spectacular fashion during the second half of the season finale. Given that the writers had spent the entire first season making this character friends with the hero, humanizing him and integrating him into the TrueCompanions, this is actually fairly stunning, especially given that this show loves sympathetic villains being redeemed the way it does.
** One could argue Gene made his original turn at the start of the series, when he threw down his stepfather and took the role of Mandarin for himself. Outing himself to his friends after they out themselves as Team Ironman just sealed the deal.
** Whitney Stane has often straddled the line between good and evil ever since she's donned the identity of "Madame Masque", going from UnluckyChildhoodFriend towards Tony to StalkerWithACrush to him, with murderous tendencies towards her father, to redemption, to a brief AntiHero stint as Madame Masque, and LaserGuidedAmnesia that led her to be DemotedToExtra. [[spoiler: Her heel turn is permanently established in "Iron Monger Lives!", where she remembers Tony's identity as Iron Man and her time as Madame Masque. She returns as Masque to hatch an elaborate scheme in order to ruin Tony's life and kill his friends and family. By the time the episode ends, she seems to be continuing her villainous persona and her vendetta.]]
* Jojo does this in a rather epic fashion in ''ThePowerpuffGirls'' movie, in what also counts as a CrowningMomentOfAwesome: "[[LargeHam The hobo formerly known as Jojo is no more! From this day on, I shall be known as... MOJO Jojo!]]" Then again, he was EvilAllAlong, so this might not count.

* A fictional pro wrestling example. In one episode of ''{{Futurama}}'', Bender becomes a popular robot wrestler named Bender the Offender. After his popularity fades, management turns him into the Gender Bender.
* HannaBarbera's Muttley CaptainErsatz as well as Series/{{Columbo}} {{Expy}} Mumbly was made a bad guy in ''{{Laff-A-Lympics}}'' and ''Yogi Bear and the Magical Flight of the Spruce Goose'' because they didn't have all the rights to ''WackyRaces'' at the time and [[TheyJustDidntCare couldn't be bothered]] to create a new character.

* Parodied in ''EdEddNEddy'' when, after a misunderstanding caused the other kids to beat up Captain Melonhead (Jonny) and Splinter the Wonder Wood (Plank), they face heal turned into The Gourd and Timber the Dark Shard to get revenge on the cul-de-sac. [[spoiler: Too bad the movie was over.]]
* BarnacleBoy in ''WesternAnimation/SpongebobSquarepants'', however it's only for one episode over the fact he wasn't allowed to have an adult-sized Krabby Patty.

* [[WesternAnimation/MyLittlePonyFriendshipIsMagic Princess Luna's]] descent into Nightmare Moon
* ''WesternAnimation/WinxClub'': Riven in season one, Bloom(via MindControl) in season two, and [[spoiler:Aisha]] in season four.

* ''[[TheCloneWars Star Wars: The Clone Wars]]'': [[spoiler:Captain Argyus, Slick, Pong Krell.]]'
* The Silver Surver on TheSuperHeroSquadShow was so corrupted by the infinity sword, that he turns his back on Galactus and even [[TheStarscream tricks]] Thanos into giving him the complete Infinity Gauntlet. It's rare for a Face Heel Turn to pull a Starscream, but Silver Surfer pulls it off well and becomes the new BigBad till the end of the series.
* General Modula did this prior to the start of ''{{Sym-Bionic Titan}}''. He's seen as one of the good guys in the WholeEpisodeFlashback "Shadows of Youth." What made him turn was not answered.
