History TookALevelInKindness / WesternAnimation

** Arcee and Ratchet of ''WesternAnimation/TransformersPrime'' become kinder and more open towards their human compatriots as the series progresses. On the same track, Agent Fowler becomes friendlier towards the Autobots, serving as a staunch advocate on their behalf to his superiors.

** Amity Blight takes a level in kindness after getting out of the toxic influence from Boscha and the education demands from her mother, as well as befriending Luz [[spoiler:and eventually dating her]]. She also becomes friends with Willow again, although her attempts at being nice to her come off as InnocentlyInsensitive at first.
** Lilith Clawthorne becomes a lot nicer in the second season after [[spoiler:sharing Eda's curse]] and spending some time living at the Owl House following her HeelFaceTurn. She especially becomes much kinder towards Hooty and even forms and OddFriendship with him when he helps to defend her.

** [[spoiler: The Diamond Authority turn over a new leaf after Steven convinces them to heal all of the corrupted Gems on Earth. While initially it's out of respect for Steven's requests, Steven Universe Future shows their attempts to change are completely sincere and are actively making the galaxy a better place for all gemkind.]]

** [[Characters/TheAmazingWorldOfGumballGumballWatterson Gumball Watterson]] started off as a NiceGuy, but [[TookALevelInJerkass took several levels of jerkass]] in Season 2. Season 3 actually made him a genuinely nicer kid by showing him helping others instead of being snarky or apathetic. There was even an episode called "The Name" that extracted and ultimately destroyed his JerkWithAHeartOfJerk attitude! Every episode from there up to the end of Season 4 Gumball averts CatsAreMean on a daily basis. By Season 6 this status has reduced a little from 4 and definitely got better than [[TookALevelInJerkass Season 5]]. His kindness is arguably greater than before to the point he genuinely befriended [[spoiler: Alan]] and [[spoiler: got his mother Nicole and her parents to forgive each other]] he now just hides it under [[SheepInSheepsClothing pretending to be an indifferent blatant jerk to keep up his status]].

* ''WesternAnimation/{{Amphibia}}'': At the start of Season 3, [[Characters/AmphibiaSashaWaybright Sasha Waybright]] finally overcome with [[MyGodWhatHaveIDone huge remorse over her past actions]] and decide to pull a HeelFaceTurn by helping the Wartwood citizens fighting against the Frobots and forming a Wartwood Resistance to fight against King Andrias and his army. As the leader of the Resistance, she became a BenevolentBoss to the rest of the members and began to treat them very well, no longer relying in toxic manipulation and control.

** [[Characters/TheOwlHouseLilithClawthorne Lilith Clawthorne]] becomes a lot nicer in the second season after [[spoiler:sharing Eda's curse]] and spending some time living at the Owl House following her HeelFaceTurn. She especially becomes much kinder towards Hooty and even forms and OddFriendship with him when he helps to defend her.

* The Joker of all people in Season 3 of ''WesternAnimation/HarleyQuinn'' since he decided to become a full time husband to Bethany and stepfather to her children. In the first two seasons he was his insane, manipulative, abusive, homicidal self from the comics. But in Season 3, while still showing hints of insanity and a capacity for violence, Joker is able to control himself, is much nicer, tries to avoid killing people, and even risks his life to save his stepfamily.

* [[Characters/AdventureTimeIceKing The Ice King]] and The Earl of Lemongrab get these in ''WesternAnimation/AdventureTime''. The Ice King goes from being a villain to being a mere nuisance who tries to hang out with Finn and Jake because he wants to be their friend. Lemongrab becomes a nicer person after Princess Bubblegum makes him a clone of himself so he won't be lonely and misunderstood- which leads to him releasing his prisoners who, apparently, no longer harbor any ill will towards him. In following episodes, Lemongrab is shown to be a little bit calmer and a little bit less resentful of other people. Later subverted, however, in the case of Lemongrab. He initially seems to be getting better after his clone is made (though still an asshole), but he takes a hard turn for the MoralEventHorizon in "Too Old".

* King Julien XIII in ''WesternAnimation/AllHailKingJulien''. While in other Madagsacar related media, he is self-centered at best (the movies), and an antagonist at worst (Penguins of Madagascar), as the primary protagonist his rougher edges are smoothed out. While he can still be self centered and can suffer from tunnel vision when he sets his mind to something, overall it's shown that he does have his citizen's best interests in mind and does genuinely care about them.

** Tina Rex was a [[BarbaricBully brutal bully]] in seasons 1-2. After [[TheSpeechless she had no speaking role]] in season 3, she became a better person in season 4, though sometimes she is still a bully.

* Rose from ''WesternAnimation/AmericanDragonJakeLong'' has this in season 2, following the moment of finding out Jake is the American Dragon by the season 1 finale.
* [[Characters/AvatarTheLastAirbenderZuko Prince Zuko]] from ''WesternAnimation/AvatarTheLastAirbender'', during season 3, after his [[spoiler: HeelFaceTurn.]]

* The Joker of all people in season 3 of ''WesternAnimation/HarleyQuinn'' since he decided to become a full time husband to Bethany and stepfather to her children. In the first two seasons he was his insane, manipulative, abusive, homicidal self from the comics. But in season three, while still showing hints of insanity and a capacity for violence, Joker is able to control himself, is much nicer, tries to avoid killing people, and even risks his life to save his stepfamily.

* June from ''WesternAnimation/KaBlam'' became this in season four. She still had some cynical moments, but she became a lot nicer.

* Kim herself, yes the title character of ''WesternAnimation/KimPossible'', has this happen to her. During the first season she was fairly bossy and up herself, not uncaring or unfriendly, but something of a hypocrite and would brag about how good she is. Segue to season two and these traits were pretty much gone with her efforts being more ItsWhatIDo and less showing off.
* [[Characters/KingOfTheHillDaleGribble Dale Gribble]] from ''WesternAnimation/KingOfTheHill'' evolved from a crazy, slightly sociopathic JerkAss into a still crazy but much more likable character by around season four. You can tell by his VocalEvolution, by the way. Kahn never fully stopped being a condescending jackass, but he did eventually find some common ground with Hank and the rest of his neighbors and came to grudgingly consider them friends of his.

** Mitchell was, for the majority of Season 1, a jerk. However, once he finally befriends the main kids in the ChristmasEpisode, he seems to have mellowed out more, especially in the latter half of season 2. Compare "Mindy's Mystery" to episodes like "Sean's Robotic Arm" or "Try and Try Again", and you'll notice massive character growth.

** [[Characters/TheSimpsonsHomerSimpson Homer Simpson]]. During season 1 he used to be angry all the time, but he became sweeter after season 2. Then, when the show's {{Flanderization}} kicked in, he TookALevelInJerkass. Though DependingOnTheWriter, he occasionally snaps back to being nice, then back to a jerk, and so on. This evolution had begun since the show's beginning. Even Season One Homer is a far more sentimental and devoted father in comparison to his counterpart in ''Series/TheTraceyUllmanShow'' shorts. And then there's "Alone Again, Natura-Diddily", where Homer promises to treat Ned Flanders less like a SitcomArchNemesis, complete with a SingleTear (this was in response to Ned's [[spoiler:wife dying in a freak accident]], so they had to make him act nicer toward Ned). The one episode where he becomes friends with Flanders, [[SnapBack he's back to hating him by the end]], it's just not shown or explained how. In season 33, he's shown to be much more receptive of his children, clearly making an attempt to cheer up Lisa in "Lisa's Belly" and Bart in "My Octopus and a Teacher"; in the latter, his advice ends up helping Bart, and incidentally Lisa.

** Nelson Muntz, who started out as a bully from the wrong side of the tracks, has shown tendencies of this after season 6, often missing his DisappearedDad (who shows up once in a while) when he went out to pick up some cigarettes and never returned, convincing the other students to visit the Moon River Theater in Branson, Missouri so he could enjoy an Andy Williams concert (although he ''does'' punch Bart to get him to stop at the concert hall), and occasionally dating Lisa after she gave him $50 to start up his own business. He's on better terms with Bart, too; in "The Debarted", Bart calls Nelson his "other best friend" after Milhouse, and in "Postcards from the Wedge", "Stealing First Base", and "My Octopus and a Teacher", they're able to have serious conversations with no bullying involved.

** [[Characters/SouthParkStanMarsh Stan Marsh]] and [[Characters/SouthParkKyleBroflovski Kyle Broflovski]] (and to some extent Kenny) also gained shades of this. In earlier episodes, they were arguably worse than [[JerkAss Cartman]], being obnoxious {{Bratty Half Pint}}s who had nothing against bullying or manipulating anyone lower on the chain than themselves. As Cartman TookALevelInJerkass however, they were mellowed out to act as foils to him and the other [[OnlySaneMan increasingly insane residents of the town]]. This is particularly prevalent in their treatment of [[ButtMonkey Butters]], while they mistreated him just as frequently as Cartman in season six, as early as season seven they are on more friendly terms and take exception to using him as a patsy for a prank gone wrong.

** '''[[Characters/SouthParkEricCartman Eric Cartman]]''' himself has come to this territory. If you believe that his actions do show a character so evil and despicable, watch the episode "The Death of Eric Cartman". In it, Cartman seeks self-redemption by believing that he was dead. Another good example of this would be by the end of the episode "Jewpacabra" where he finally accepts the Jews. Speaking of Cartman, in general, he has taken quite a level of kindness from season 16 and the end of season 15, being less racist and evil, trying to show respect for Kyle in many expectations and even befriending him. He's also shown to be more [[AdaptationalHeroism heroic]] [[PetTheDog and friendlier]] in the show's [[VideoGame/SouthParkTheStickOfTruth latest]] [[VideoGame/SouthParkTheFracturedButWhole video]] [[VideoGame/SouthParkPhoneDestroyer games.]]
** [[PoliticalOvercorrectness PC Principal]] was basically a thin-skinned bully, beating up and haranguing kids for the most minor things. In season 20, he has become much more patient and tolerant.

** Thomas started off as a cheeky, {{attention|Whore}}-seeking BrattyHalfPint, and even [[AcquiredSituationalNarcissism became noticeably arrogant after he was given his own branch line]] in the first two seasons, although a couple of BreakTheHaughty moments kept him in check, but as of season 3 and on-wards, he became more kind and altruistic, especially in ''Trust Thomas'' where he agreed to do James' work despite that James was pretending to be sick, and even showed no hard feelings when he apologized for playing said trick.

* ''WesternAnimation/TheTransformers'': Grimlock and the other Dinobots become much, much nicer following the twenty year TimeSkip between season 2 and ''WesternAnimation/TheTransformersTheMovie''. Before, they was extremely dismissive of Optimus and the other Autobots and had a strong rebellious streak that the Decepticons were able to take advantage of. By the time of the movie, Grimlock in particular was more of a loyal simpleton than rebellious jerk.

* Dale Gribble from ''WesternAnimation/KingOfTheHill'' evolved from a crazy, slightly sociopathic JerkAss into a still crazy but much more likable character by around season four. You can tell by his VocalEvolution, by the way. Kahn never fully stopped being a condescending jackass, but he did eventually find some common ground with Hank and the rest of his neighbors and came to grudgingly consider them friends of his.
