History HeelFaceRevolvingDoor / WesternAnimation

* A common character type in kids cartoon shows, especially in the 80s, was the one [[{{Jerkass}} obnoxious]] member of the regular cast who could be counted upon to do something stupid, selfish, and/or rude and act contrary to the interests of the group whenever the plot focused on their everyday lives, but was considered just one of the gang when the plot focused on the world outside the main characters. They'll be trying to get the other characters expelled from school just to win an essay contest one week, then heading to the amusement park with the gang like nothing happened the next. Examples include Junior on ''WesternAnimation/TheSnorks'', Brainy on ''WesternAnimation/TheSmurfs1981'', Bianca on ''WesternAnimation/BeverlyHillsTeens'', Eric on ''WesternAnimation/DungeonsAndDragons1983'', and Reggie on ''WesternAnimation/TheArchieShow.'' Modern versions on non-kids shows would include Cartman on ''WesternAnimation/SouthPark'' and Stewie on ''WesternAnimation/FamilyGuy.''

* [[Characters/TeenTitans2003Terra Terra]], from the animated version of ''WesternAnimation/TeenTitans''. She started off good, but after a HannibalLecture from [[ManipulativeBastard Slade]] in her first outing with the team, mingled with her own paranoia, she mistakenly believed Beast Boy had gone behind her back and told Robin about her PowerIncontinence, so she ran away from the Titans. Off-screen, she hooked up with Slade, [[FaceHeelTurn agreeing to become his agent in exchange for his help in honing and controlling her powers, going so far as to become a spy inside the Titans after he was done training her]]. During her time as TheMole, she fell for Beast Boy and tried to manipulate events so he wouldn't be captured/killed by Slade when she finally betrayed the team, but Slade appeared before them when they were on their date and revealed to Beast Boy that Terra was his double agent. Beast Boy angrily telling Terra that she didn't have or deserve any friends [[HeelFaceDoorSlam made Terra push aside any guilt and throw herself wholeheartedly into being Slade's minion]]. As a result, she fought and seemingly killed the Titans, but they escaped, rallied and attacked her. The combination of nearly losing to them, [[YouHaveFailedMe Slade's abusive treatment for failing]], and a KirkSummation from Beast Boy all pushed her to make a final HeelFaceTurn and resulted in a HeroicSacrifice.

* [[WoobieDestroyerOfWorlds The Ice King]] on ''WesternAnimation/AdventureTime''. He's genuinely a nice guy (the main characters now consider him a friend), and he has good intentions, but his mind is too warped by the [[ArtifactOfDoom Ice Crown]] to [[ObliviouslyEvil realize when his actions are hurting people]], meaning that Finn and Jake still have to defeat him from time to time.

* ''WesternAnimation/AvatarTheLastAirbender'': Zuko found himself constantly switching sides due to his confused feelings and lack of resolve. Halfway through the third season, he finally made up his mind, but even before that he was trying to save Aang half the time, mostly for his own selfish purposes. {{Lampshade|Hanging}}d in one episode when no one takes his HeelFaceTurn seriously, and he accidentally burns Toph (the one hero who DID take it seriously).

* Bender from ''WesternAnimation/{{Futurama}}'' embodies this far too often to list every instance, so here's two examples: In an episode where he lost use of his body, he became a musician and inspired thousands of broken robots, only to turn it into a scam when he recovered (and didn't tell anyone). In another episode, he and Fry join the military just so they can get military discounts, but when an actual war happens, Bender ends up throwing himself on top of an explosive to protect his fellows without a second thought, knowing full well that the blast will probably kill him. Generally speaking he's a MagnificentBastard, but he's occasionally shown that there are some things he actually cares about more than his own selfish ends.

* Discord of ''WesternAnimation/MyLittlePonyFriendshipIsMagic''. His premiere had him as a full heel. He turned partially face in Season 3 thanks to Fluttershy, turned heel again at the end of Season 4, but turned full face at the end of that episode.
* ''WesternAnimation/PhineasAndFerb'': Dr Doofenshmirtz is a self-proclaimed [[MadScientist evil scientist]] bent on taking over the Tri-State Area and has done many evil schemes which always fail, either due to his incompetence or Perry's interference. However, he has on many situations [[VillainousRescue joined the good side and helped defeat several other great villains]]. Despite all of his heroics, [[AesopAmnesia he still insists that he is evil and continues with his schemes in later episodes.]] He always circles back and forth between both sides depending on the episode plot.

* Butters from ''WesternAnimation/SouthPark'' oftentimes seems to end up working with Cartman on whatever his latest scheme is. Given [[ThePollyanna Butters]] personality, however, it's more likely he just doesn't understand what he's doing.
** Cartman himself has been through the door a few times. While usually a villain of some sort, there are times when he's treated as no more than just a jerk, rather than a person capable of mass murder. There are also times when his goals are almost selfless or his goals align with the 'heroes' of the episode enough that he's effectively the {{Big Damn Hero|es}}.

* Terra, from the animated version of ''WesternAnimation/TeenTitans''. She started off good, but after a HannibalLecture from [[ManipulativeBastard Slade]] in her first outing with the team, mingled with her own paranoia, she mistakenly believed Beast Boy had gone behind her back and told Robin about her PowerIncontinence, so she ran away from the Titans. Off-screen, she hooked up with Slade, [[FaceHeelTurn agreeing to become his agent in exchange for his help in honing and controlling her powers, going so far as to become a spy inside the Titans after he was done training her]].

The combination of nearly losing to them, [[YouHaveFailedMe Slade's abusive treatment for failing]], and a KirkSummation from Beast Boy all pushed her to make a final HeelFaceTurn and resulted in a HeroicSacrifice.

* Courtney in ''WesternAnimation/TotalDrama'' is one of the most prominent examples due to her changing morality in each season. She begins as good/neutral in early-''Island'', changes to evil in late-''Island'' and ''Action'' where she serves as the BigBad, reverts back to good in the first half of ''World Tour'', before returning to evil in the second half, turns good halfway through ''All-Stars'', before being evil once again in her elimination episode. Needless to say, she's arguably one of the most frustrating cases of this trope in recent years.
