[[folder:The Fairly Oddparents]]
* Timmy Turner of ''WesternAnimation/TheFairlyOddParents''. During the first few seasons of the show, Timmy was portrayed as essentially a good kid who occasionally gave into his selfishness. However, he was still very likeable. By about the fourth or fifth seasons, though, he became a {{jerkass}} along with all the other denizens of [[CrapsackWorld this hellish parody of sitcom America]], including his Fairy Godparents who were summoned to help him the first place. Timmy has returned to most of his original affable characterization by the sixth season onward but it still shows up every now and again.
* Cosmo was originally simply TheDitz and a bit of a {{Cloudcuckoolander}}, sometimes dim but still relatively normal, and perhaps strangest of all, he and Wanda seemed to be on an equal level of airheaded and careless intelligence ("We're two halves of a whole idiot!") Starting around Season 2, he started to become increasingly dumber with each season. Now he's just TheDitz. Just look back at his character in the original ''WesternAnimation/OhYeahCartoons'' pilot -- he was actually a suave and sophisticated guy, barely resembling the character he became. Also, his relationship with Wanda in Seasons 4 and 5 was the foil for a lot of marriage jokes; in a couple of episodes, he claimed to be trapped in the marriage to Wanda and that she had tricked him into it. This characteristic was toned down in Season 6, when the birth of Poof turned them into loving parents.
* Wanda was originally portrayed as being ''dimmer than Cosmo'', believe it or not, then at around Season 1 they shared an equal amount of intelligence. From Season 2 onwards, Wanda became simply the [[WomenAreWiser wiser]] one who chastised Timmy and Cosmo whenever they did something wrong. Then, all her jokes tend to be that she's a total nag, to the point where the BarbarianHero episode had her become the [[WhipItGood whip cracking]] Nagules. Her marriage to Cosmo also became one of the biggest sources of humor on the show, to the point where Cosmo made it appear that he was trapped in the marriage to Wanda; however, this was toned down in Season 6, when the birth of Poof brought them closer together and they are currently revamped as loving parents.
* Timmy's parents. They go from busy and clueless to ''extremely'' negligent parents. This was actually the plot catalyst in an episode guest starring Steve Irwin as 'The Bad Parent Hunter'.
* Vicky was originally just a bully whose worst trick was {{blackmail}}ing Timmy into doing chores by revealing false evidence that he cheated on a math test or wrecked the house while his parents were out, but otherwise was depicted as being apathetic to Timmy and more complacent with sitting around watching TV. Now, she wants to TakeOverTheWorld, is ferocious enough to intimidate and whip all the other villains into shape, and goes out of her way to harm Timmy and does little to cover up her actions because no one will stop her anyway. In the early episode "The Big Problem", Vicky freaks out when Timmy goes missing under her care; although this was only out of concern for herself, at least she intended to do her job correctly. In later episodes, she plots violence against him and doesn't care about his well-being at all.
* Jorgen Von Strangle, like Cosmo, went through two Flanderizations. He begins as a stern Terminator parody, and had little real personality apart from brutally hurting other characters and destroying things whenever he is set to do a job. His first Flanderization comes somewhere in Season 1. He becomes the boss of all fairies (which was undetermined before, and he was only assumed to have [[WhyDoYouKeepChangingJobs every job a higher official could have]]), and has more of a personality. He now has a reason to brutally harm others; he's a sadist with monstrous power and a very well defined and muscular body compared to all the other fairies. See the connection. He then shows much more enjoyment in beating, humiliating, and gloating in front of all the fairies. But in Season 6, he goes through his second Flanderization. He becomes a PluckyComicRelief character who never uses his power in dire times, only his body. It's as though he isn't even a fairy anymore, or the boss of fairies at that. If this weren't noticeable enough, he becomes a perfect ally and even a dear friend to Timmy. They were always his closest friends, but now he doesn't even ''punch Cosmo'' anymore!
* Trixie Tang was always the AlphaBitch, but her early appearances suggested she had [[HiddenHeartOfGold a nice side to her]], and that she had a tomboyish side. Now she's just a stereotypical AlphaBitch.
* While [[EvilTeacher Mr. Crocker]] was always a bit crazy, in the earlier episodes his usual demeanor was more stoic and grouchy, only veering into maniacal insane behaviour when there were fairies at work. A lot of his insanity was perceived by the other characters due to him being TheCassandra, and his fairy hunting tools were more grounded in reality (for this show, anyway). Now he has a huge lab underneath the school (to the point where it's lampshaded) and he's every bit as crazy as everyone perceives him to be. Sometimes these days it seems like he can't even form a sentence without "FAIRY GODPARENTS!" in it somewhere. He also became MUCH more fond of giving students failing grades. In his earliest appearance, he was either snarky or silent when he gave kids F's. Now he's flat-out sadistic about it and it's one of the only things that makes him happy. Hell, in his first appearance, he didn't even give out Fs, but Ds.
* AJ was originally just the smartest kid in Timmy's class. Now he rivals [[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]] in terms of brains-- a connection that was not lost in the third ''Jimmy/Timmy'' special.
* Chester was originally just a lower-income kid who lived in a trailer and whose father was a disgraced baseball player. Now he eats garbage and such things with so much vigor you wonder what he would do if he were rich. Also, near the beginning he appeared more down to earth in comparison to AJ, but now he's just a DumbBlonde.

[[folder:Family Guy]]
Various characters of ''WesternAnimation/FamilyGuy'', due to the writers usually taking one joke that was successful before and building on it in future episodes:
* Peter himself has always been a {{Jerkass}}, but in the earlier seasons he was shown with a [[JerkWithAHeartOfGold genuine good side]] and actually cared about his kids, even Meg. Peter's intelligence also drops from 'idiot' to 'legally mentally disabled'. His original flanderization came after "Petarded" where he started to rip on Meg & often make jokes about her, but at the same time, was actually well intentioned & a little intelligent deep down.
* Peter's LethallyStupid tendencies were more a case of InnocentlyInsensitive behavior in early seasons, and, akin to a standard BumblingDad, being too arrogant and idiotic to quite get what he was doing was wrong. Even at that Peter usually was handed AnAesop and saw the error of his ways. Around mid Season 4 (And completely around Seasons 6 onwards), however, he evolved more into a {{Comedic Sociopath|y}}, completely apathetic to the misery he causes, and in some episodes, outright sadistic and amused by it.
* And [[UnpopularPopularCharacter let's not even go into what happened to]] ''[[ButtMonkey her]]''... Meg has "developed" from an ordinary, level-headed teenage girl with teen problems into an outrageously hated and despised punching bag whose desperation for happiness and love often makes her insane. At one point she even snaps and beats up a passing car driver who is picking on her, and stalks Brian after he goes to the prom with her out of pity.
* During season 2, Stewie started to become ''a bit effeminated'' and show ''some glimpses'' of homosexuality, and became more fond of Brian as time went by. From season 6 onwards, he lost all of his former EnfantTerrible traits, and started to crosdress on a daily basis, dates other guys dressed as a girl, openly wants to have sex with Brian and blatantly hints that he's gay every five seconds.
* Lois' sexuality has become greatly Flanderized overtime. Originally she enjoyed a healthy sex life with her husband, yes, but it's gotten to the point where in at least ''four'' different episodes (when Peter became abstinent, when Peter became gay, when Peter got a vasectomy, and when "real life was censored"), she's been shown to be ''unable to properly live her life'' unless she can have sex with Peter.
* Aside from her sexuality, Lois also started off as being a legitimately caring mother who even attacked a group of girls for making fun of Meg. Unlike the other characters, her flanderization came much later. Since Season 6, she's been consistently shown to be extremely abusive to Meg, even going so far as to suggest Meg commit suicide because she doesn't want to put up with her daughter's depression anymore. Her callousness seems to be exaggerated outside Meg (which could have at least [[RuleOfFunny been excused by EVERYONE hating her]]). By the eight season what were merely a few out of character moments to remind she was NotSoAboveItAll slowly eclipsed her original more logical persona to the point she was a DistaffCounterpart for post Flanderization Peter, a [[PsychopathicManchild childish]], [[LackOfEmpathy self centered]] [[ComedicSociopath heckler]] constantly bullying her family and friends [[ItAmusedMe for kicks]]. Half the time she is shown giggling or joining in on Peter's antics, something she showed nothing but disdain for early on.
* Chris has also gotten a small, but noticeable flanderization, abruptly insulting others for no reason and gaining a cynical edge to him. His relationship with Meg has taken a strange turn also. It has been revealed that Chris and Meg practice kissing on one another, unknowingly made out with each other at a Halloween party and is implied to take baths together. Even Peter himself was shocked!
* The supporting cast has fallen into this trope as well. Joe Swanson went from just a handicapped character (who in fact was greatly competent despite this and admired by everyone because of it) to everything involving him leading to a "Get it? Because he's a cripple" joke with rage tendencies, and Cleveland lost his quiet, boring personality to become the butt for black jokes.
** Cleveland originally was the calm, soft guy. However when he got his [[WesternAnimation/TheClevelandShow own show]], his personality morphed into the abrasive, crude and cynical sitcom father character (to [[{{Expy}} fit in the role of leading male]] having a personality more similar to that of Peter and American Dad's [[WesternAnimation/AmericanDad Stan Smith]].
** Joe Swanson got even worse as time has gone on-his rage issues are more or less gone and now he's just a sad sack whose completely inferior at everything because he's handicapped. He can't even use the toilet for god's sake!
** Everybody noticed how Quagmire went from a pervert to a potential rapist, but he suffered a second flanderization much more prominent and fast: in Season 8, it was revealed that he hated Brian. Before Cleveland's departure, Quagmire seemingly had no beef with Brian and even allowed him to stay at his house at one time. In recent episodes, Quagmire has brutally assaulted Brian for unknowingly dating his transgendered father, furiously ranted at him for things Brian didn't know, and ran him over with his car.
*** Quagmire's overall [[TheWackyGuy wackiness]] and perverted tendencies have been toned down in a favor of making him a SelfDeprecation avatar in the Steve Callaghan seasons. Even when Brian isn't around he seems a lot more down to earth and rather prudish and cynical on occasion. Whether this counts as Flanderization or subversion is hard to say.
**** For the first few episodes of Season 12, Quagmire's personality reverted back to the way he was in the Zuckerman and Goodman and Sheridan era. Until "Life of Brian".....
** Bonnie slowly shifted into a long suffering woman who was bitchy and unhappy with her marriage around the time Joe started turning into a one-dimensional cripple joke. Some recent episodes have even gone as far as implying that she wants Joe dead by this point.
* In earlier episodes, Brian was cast as the intelligent, witty one in the family. When the show was uncancelled, he started to voice his left wing views and contempt for religion, and later Brian's character was swallowed by his political views, much to the fans' frustration.
** The political facets itself have also been dumbed down. In its initial form, Brian was originally your average cliche left wing caricature (i.e. condescending and self righteous but still well meaning and earnest in his beliefs), he slowly just devolved into a sleazy StrawHypocrite, flip flopping views to give himself moral superiority, and often babbling pretentious rants even he barely understands in a desperate ploy for [[AttentionWhore attention and dignity]].
** Infuriating given his statement in the very first episode that he didn't vote, and in "The Thin White Line" when he thanks God for blessing him with his nose.
** His insisting that [[PunctuatedForEmphasis "God! Is! Pissed!"]] when Peter's blasphemous behavior causes the ten biblical plagues to descend on the family. In that same episode Brian immediately interprets a power outage, fleas, and blood as three of the Ten Plagues of Egypt, a response you wouldn't expect from a staunch atheist.
** More than his politics became Flanderized. Originally he was a very smart, and sometimes even pretty classy, character, even if he did drink from time to time and had trouble getting women to go out with him because most of the women he dated were airheads with hot bodies. Now, he's a full-blown alcoholic, he's not very sophisticated, and a lot of his plotlines now revolve around him trying to get a date, always one with a human woman.
** Brian's tendency to date stupid women with hot bodies was originally played as something that frustrated him because he was really in love with Lois. Over time it became that he dated dumb women so he could feel smarter than them. On the other hand his love for Lois has just been made it almost an obsession and is very creepy. Both these aspects were brought up by Quagmire in his TheReasonYouSuckSpeech directed at Brian.
** On top of this, Brian's flanderization when it comes to meeting women was turned up a few notches when he goes to date Stewie's preschool teacher, a woman who is clearly unqualified for the job, ignoring their injuries and a ''dead child''! This is driven further when Stewie comes home with his arm out of the socket and tries to tell Lois when Brian shuts Stewie up just so Brian can keep dating the teacher. Brian eventually turns the teacher in to the police but only because the woman had a boyfriend already (naturally with an ever-hypocritical "there's a special level in Hell for people like you" comment as she's dragged off by the police).
** Brian's failures in dating women was also brought to light when Stewie brought him every single woman Brian dated and had them explain to him why they broke up with him (jealous, callous, insecure, pretentious, and [[ArsonMurderAndJaywalking has a small penis]]). Rather than taking what the women said to heart, Brian tried to flip it around by pointing out why all the women he dated were flawed instead of actually taking responsibility for his own actions, a trait that seems to have stuck to Brian's character.
** In a case of a de Flanderized trait, Brian was also extremely deadpan in early episodes, to the point of bordering TheStoic. By the end of the pre-cancellation run, he is a fully emotional character and more prone to neuroses.
* Lois's father, Carter, used to be an intelligent and rich businessman, even if his views are stuck from the 1950s. As the seasons went on, Carter's behavior is almost comparable to Peter's flanderization where he will say the most stupidest things or do the most ridiculous acts (mostly to Peter) just because he is rich and powerful and [[ItAmusedMe needed a quick giggle.]] The point is driven further home where Carter loses his assets a few times and it's shown that he cannot function in life without his fortune. He gets flanderized even further into a borderline monster in "The Old Man And The Big C" as it's revealed that his company developed a cure for cancer several years ago but he refuses to release it to the public all so he can increase corporate profit by making money off of sick people who have to rely on medication. Even after Lois lectures him about it Carter still refuses to release the cure, throwing him straight into CorruptCorporateExecutive.
* Fandom example: The Phony Guy is nicknamed "Holden Caulfield"; as a Flanderization of the actual [[Literature/TheCatcherInTheRye Holden Caulfield]]
* The entire character cast has been flanderized to the point where they just roll with it because that's who they are. For example, Meg knows she is the ButtMonkey of the group and is getting used to it, but still strives for something better.
* It has even got to the point where some characters have started to come back a few steps.
* All of the characters flanderized traits were amped up to 11 in Season 8, to the point of where the characters were coming a few steps back a bit after that season.
* Adam West in the first three seasons was a kooky and somewhat incompetent mayor. After the revival he's insane and extremely corrupt.

[[folder:Futurama]]
Like most long-running sitcoms, ''WesternAnimation/{{Futurama}}'' ends up Flanderizing most of its cast.
* Philip J. Fry started out as just an ordinary, kinda dumb 20th-century everyman. After accidentally [[HumanPopsicle getting cryogenically frozen for a thousand years]], he was just your average modern college dropout trying to adjust to an unrecognizable sci-fi future where everyone he ever loved was long-dead. Within a few episodes of the pilot, his below-average intelligence started getting more pronounced until he was too stupid to be real, even by modern standards.
** WordOfGod says Fry was intended to be a normal guy the audience could relate to and humor would be derived from his inability to cope with his strange new surroundings... but he [[UnfazedEveryman ended up adapting far faster than the writers had planned]], so they made him into an IdiotHero to keep the comedy flowing.
** In another sense, Fry's character actually deepened over time. It's hard to imagine the Fry of the first season becoming the soulful romantic who not only wins Leela's love but even (mostly) deserves it by the end of the original run.
** A lot of his perceived Flanderization also comes from his [[DemotedToExtra diminishing screentime]] over the show's run. Whenever an episode wasn't focused specifically on him, he would generally stay in the background and only come out when the script called for a gag out of him. On the occasions that they were, he proved himself a uniquely clever GeniusDitz.
* Amy's ditziness and shallowness was played up as the series progressed (few remember that she was originally an engineering student working with the professor), along with Leela's love of violence. Recent episodes have attempted to acknowledge Amy's stated intelligence by letting her finally earn her Ph.D, and actually assisting the Professor on inventions (the brain switch machine for example) around the last few seasons.
* Bender has gone through multiple flanderizations. When we're first introduced to Bender he can't live with himself because he learned the girders he bends are used to make suicide booths. [[note]]Admittedly this was kind of a one-off joke, highlighting the absurdity of the fact that Bender has no trouble making use of said suicide booths himself[[/note]]. Later, when he and Fry became roommates a gag featured him muttering "kill all humans" in his sleep. This gag grew into a complete disregard for human life. In later seasons this completely reversed given his experience on the robot planet, that he lived with a human, cared for a race of minute aliens, [[spoiler:grew attached to those orphans]], fell in love, [[spoiler:partly merged his programming with a female personality]], and underwent a sex change and back (twice), there is character development and also material manipulation of his mind there. His original (or at least post-lightbulb) character of lone, hurtful, dissolute renegade with a begrudged affection for Fry and Leela has been displaced by a jokey persona.
** This got to the point where in the Comedy Central seasons, Bender actually commits murder. ''Benderama'' and ''Fun on a Bun'' are primary examples.
* Perhaps the biggest victim of Flanderization in WesternAnimation/{{Futurama}} is Dr. Zoidberg. When he was first introduced, he was a [[JokeCharacter one-joke character]]: an alien doctor who treats humans, despite being ignorant of their biology (and oblivious to the fact). Despite this, the rest of the cast actually treat him with the kind of respect usually accorded doctors throughout season one. But after he got his own episode in season two ("Why Must I Be a Crustacean in Love?") where it was revealed that Zoidberg is considered a loser by his own species' standards, he became the ButtMonkey of the series. Jokes about him tended to focus on his being poor, gross, completely unpopular with the rest of the cast, or all three, while the incompetent doctor jokes tapered off (though the writers do still crack one from time to time). His background participation in "Where the Buggalo Roam" (in which he spends the entire episode freeloading off the Wongs) just hammers the point home.
** This may be reversing, however; a Season 6 episode ("The Tip of the Zoidberg") shows that he really is a brilliant xenobiologist and that his poverty comes from the fact that he chose to work for his friend Professor Farnsworth out of loyalty when he could have had a high-paying job under Mom.
* Hermes Conrad was an ObstructiveBureaucrat from early on, and episodes like "Lethal Inspection" deepened his characterization. His Flanderization is more to do with him being a pothead (as seen in "Bend Her," when Hermes mentioned that the Olympic limboing team from Jamaica was detained at the airport, in "The Sting," when his wife seeing him burning Fry's time card during his funeral, asks him: "Can't you go anywhere without lighting something up?", and in "Bender Should Not Be Allowed on Television," when his son found a "cigar," then tried to deny that it was his). With considerable restraint, the series went several years without any marijuana jokes for its Jamaican character; now they can't seem to get enough of them [[note]]though this could be because Comedy Central's censors are a bit more liberal about marijuana jokes than FOX is. Remember how FOX digitally blurred out Oscar's hand smoking a joint on ''Series/ArrestedDevelopment''? Or how the ''WesternAnimation/FamilyGuy'' episode where Peter and Lois become musicians for a talent show had to shoe-horn a message about how pot was bad and wasn't contributing anything to their creativity, though how an episode like "420" -- where Brian fights to have marijuana legalized -- got approved to air is beyond anyone's guess (although it could be that he has the law repealed because society can't function while high)[[/note]].
** It's not so much that they completely restrained from marijuana jokes at first, more that originally they were rare and subtle, certainly nothing a child would notice. After the revival Hermes apparently stopped being sneaky about smoking and just gave up on bureaucracy to become the resident stoner.
* Turanga Leela started as very archetypal captain figure, the {{Straight|Man}} ActionGirl that was sorely needed to run a crew and company that were barely competent in their own individual rights, occasionally showing odd, questionable quirks that kept her safely out of MarySue territory. In each successive season (especially the ComedyCentral ones), the latter aspect of her personality became increasingly prevalent to the point of consuming the reset of it, sometimes outright resembling {{Chickification}}. One could almost say that Fry didn't win her love by becoming smarter, but rather from her [[TookALevelInDumbass becoming dumber]].
[[/folder]]

[[folder:King of the Hill]]
* This series is unusual for giving flatter characters new aspects, ''then'' focusing on them, thus creating the sense of Flanderization at the same time as they get CharacterDevelopment.
* Hank Hill of ''WesternAnimation/KingOfTheHill'' is known for preferring traditional things over trendy new ones. This starts to get overdone in the later seasons; case in point, "Get Your Freak Off". In this episode, Hank is more Amish than the Amish; he's [[HonorBeforeReason almost medieval]].
** In early episodes, Hank was often cast as a voice of reason, although often too uptight and conservative; the series' later episodes portray him as an naive loser who often gets into trouble because of his own whims.
** In the series pilot, Hank was short tempered (to the point that his other CatchPhrase was "I'm gonna kick your ass!"), yet still polite. Over time, his short temper was dropped and he slowly became a near pushover.
*** He did spend an episode in anger management. While the end of that episode implied that Hank needed his rage in certain situations, maybe it actually worked.
** Hank's characterization definitely [[DependingOnTheWriter depends on the writer]]. According to [[http://www.macleans.ca/authors/jaime-weinman/a-brief-history-of-king-of-the-hill/ this article]], some members of the writing staff (Mike Judge included, obviously) liked the initial characterization of Hank as the OnlySaneMan. Others preferred to ridicule him as hopelessly out-of-touch. Unsurprisingly, the treatment of Hank varies from season-to-season, and occasionally episode-to-episode.
* Similarly, in early seasons Peggy seemed to have reasonable Spanish skills, but then they decide to play up her incompetence and overconfidence for laughs. She even boasts about her "high" I.Q. (self-estimated) and was worried about having an average I.Q. By Season Four, the producers received enough fan complaints to temporarily ratchet back Peggy's Flanderization... only to return to it shortly afterwards.
** In early seasons, Peggy occasionally took on odd jobs (like a notary public or writing musings for the local newspaper) or pursued hobbies (softball, music). Initially this makes sense: Peggy's only a substitute teacher, and she sometimes needed extra money or had free time to kill. Eventually though, Peggy goes through more jobs than Homer Simpson (reporter, realtor, call center employee, even running a restaurant), to the point where her teaching background becomes virtually [[TheArtifact an artifact]].
* In the beginning, Bobby was a late bloomer, but an otherwise ordinary kid: he was immature and impressionable, but in some ways wiser than his straitlaced family. Bobby's immaturity and impressionability eventually became the entirety of his character, to the point it's difficult to believe he was ever showing any sort of character development at all.
* Certain fans blame Luanne's shift from dim bulb to ditzy hillbilly on TheScrappy, Lucky. She's always been rather dim-witted and immature (her early trait of being a WrenchWench was soon dropped to make her a straight-up ditz), but as of late she's been nothing more or less than Lucky's wife.
** This is troubling because there were quite a few episodes where Luanne downright struggled to break free from her redneck roots -- she was even attending Community College. Then, this all went out the window when they introduced Lucky, all in the matter of an episode.
*** At least this was lampshaded in the same episode. Peggy tried everything she could to stop Luanne from dating Lucky for precisely these reasons, including pointing out to Luanne how hard she had worked to escape her trailer-park background.
* Joseph Gribble started out as an average kid seemingly a little more intelligent and athletic than Bobby, sometime afterwards when he hit puberty he was a bit awkward and adjusting to his new body, in the later episodes he becomes even more awkward and seemingly loses several I.Q. points to the point where he's nothing more or less than a dumb jock.
** Dumb Jock is an understatement. The level of intelligence Joseph displayed after puberty wouldn't have been out of place in fricking Beavis and Butthead. Despite his body growing big, his mind shrunk to the point where all he could think about is making out with his ditzy girlfriend (or trying to get another girlfriend). [[spoiler: Hell the episode where Bobby and Joseph became 'mentally disabled', while Bobby didn't need it...Joseph DID.]] And we never saw his [[TheChosenOne Chosen One]] schtick hinted at by John Redcorn.
* Speaking of John Redcorn, he's a bit of a double subversion, going from being just a one-note ChickMagnet (who was having sex with Dale's wife) to a New Age healer to having some sort of HiddenDepths as a musician to, in that same episode, most likely having a mood disorder, judging by his lyrics.
** Redcorn also goes through quite a radical change in regards to his mood swings. In the story arc of him wanting to know his son, he goes from just wanting to know his son better (where his worse reaction is grunting and rushing off in a RealMenDontCry fashion) to straight up crying on cue at every opportunity, famously (almost) on Hank's lap. A great example is when Hank admits he's having sex dreams about Nancy in which Redcorn lashes out at Hank. After Hank runs away, Redcorn bawls to himself.
* Dale Gribble started out just as a rather paranoid conspiracy theorist. After a few seasons, he turned into a completely psychotic idiot that actively caused more damage than he prevented and has unwittingly endangered himself and everyone else on Rainey Street multiple times (for example, building a tunnel under the road even after the one under Hank's house was clearly unsafe, and nearly getting himself, Bill and Boomhauer crushed by an incoming truck). Lampshaded in one episode, where Dale flat-out admits that if not for Hank, he'd have gotten himself killed long ago.

[[folder:The Simpsons]]
''WesternAnimation/TheSimpsons'', being the series which [[TropeNamers spawned this trope's very name]], has this almost across the board. Over time, the series has, in many ways, become a symbol of this trope in its purest form.
* The [[TropeNamers trope namer, Ned Flanders]], is an interesting case, as he was flanderized ''twice'':
** Pre-flanderization, he was a friendly, generous, ideal neighbour, who enjoyed going to church on Sundays and had a great family. He was better off than Homer, simply because he didn't spend money frivolously (which is why Homer hated him - he was jealous of Flanders' well-earned fortune).
** His first flanderization was into an obsessively pious, painfully generous, obnoxiously friendly milquetoast who was ''still'' a pretty decent person, if incredibly boring (at least until the episode "[[Recap/TheSimpsonsS8E8HurricaneNeddy Hurricane Neddy]]" where he snapped and verbally attacked his neighbors and the episode "[[Recap/TheSimpsonsS10E10VivaNedFlanders Viva Ned Flanders]]" where his boring, milquetoast ways are pitied, rather than celebrated).
** His second - and most damning - flanderization took his obsession with Christianity and expanded it, turning him into an intolerant bigot who demanded a lot of respect for his religion while openly mocking other peoples', such as Apu's Hinduism (see the episode "[[Recap/TheSimpsonsS16E6MidnightRx Midnight Rx]]", where even Homer isn't amused by what Ned says of Hinduism to Apu's face). This also turned the joke of "Why does Homer hate him?" into "''No wonder'' Homer hates him." It's worth noting that this second flanderization coincided with the death of his wife Maude, leading to a tragic AlternateCharacterInterpretation that the loss of his wife and having to be a single father led him to become bitter, depressed, and increasingly hostile to anything that goes against his increasingly fundamentalist religious beliefs.
** Also, the writing staff have stated that Flanders was deliberately changed in response to the increased influence of religion in politics. So Flanders' character was essentially derailed because ''The Simpsons'' writers wanted a StrawCharacter to mock. Portrayal of Flanders reached the point of full-on anti-Christian, and later on Flanders was ratcheted back towards his first flanderization of being a nice, yet kinda boring religious man.
*** Honestly, Ned's romance with Edna Krabappel saved him as far as his fundamentalism went. They don't make it clear why he was so drawn to her to start with, but in order for their relationship to work at all, he had to let go of a lot of his prudish hang-ups around sex and other "bad" behaviour and accept that Edna was far more ah, "wordly" than his previous wife. Now that she was involved in a loving relationship with a good man, Edna also seemed happy to mostly leave her wild days behind her.
* Flanders is not the only Simpsons character to have been flanderized multiple times. The whole cast has undergone sweeping personality changes.
** First was the "Golden Age" Flanderization: during seasons 2 and 3, the cast evolved into their most popular incarnations.
** Then came the "Zombie Age" Flanderization: a direct result of Mike Scully becoming the showrunner in season 10.
** Because many characters have undergone two flanderizations, character descriptions on the Internet seemingly contradict one another, but actually fail to address both personality shifts. To illustrate, one character description for Homer might say, "Homer used to be a lovable oaf, but he became meaner as the series went on." Another might say, "Homer used to be angry most of the time but became nicer and sweeter as the series progressed."
* Homer started out as a strict disciplinarian; quite unintelligent, but still devoted to being a father.
** His first flanderization turned him into a stupid yet lovably eccentric ManChild.
** Eventually, Homer became a moronic Jerkass. This second flanderization was toned down later on and, lately, [[DependingOnTheWriter depends on the writer]]. Throughout the series, his intelligence drops from average to "[[TheDitz really stupid]]" and sometimes even [[FlowersForAlgernonSyndrome clever]] or [[DumbassHasAPoint insightful]].
** Homer's stupidity might have been {{lampshade|Hanging}}d by the writers in the 138th episode, where a supposed fan 'asks' "I think Homer gets stupider every year.", after which [[YouMightRememberMeFrom Troy McClure]] says that isn't a question, but they'll let the viewers decide for themselves, and a bunch of clips of Homer's idiocy show up.
** His increasing idiocy may possibly be justified by the [[AmusingInjuries numerous head traumas]] Homer has been suffering throughout the years.
** Homer was never exactly a model of emotional control, but by Season 15 or so, he can't seem to go longer than a single episode without running out of the room and/or weeping hysterically, often over a minor slight like the kids wanting to go to dinner with their mother instead of him.
* The Simpson family's financial situation has also changed dramatically. In the earlier seasons, there was much more focus on the financial difficulties the family grappled with by having Homer be the sole breadwinner and Marge staying at home. For some reason in later seasons this concept was all but dropped, and the family now sports tablets, smartphones, individual computers, and frequently travel- all apparently on Homer's middle-of-the-road income at the power plant.
* Smithers merely started out as the exaggerated version of the brown-nosing co-worker who always sucked up to his boss, but along came jokes that just screamed that Smithers could be gay for his boss, despite that he sees Mr. Burns as a father figure since his real dad died to save the town from a nuclear disaster. Later he became not only unambiguously gay, but interested in men besides Burns. Now he's every gay stereotype in the book.
* Mr. Burns, as of late, has undergone a shift from being a ruthless, black-hearted corporate tyrant to a doddering old man with a skewed, quasi-Victorian conception of society. While the writers attempt every so often to enforce his villainous tendencies, his role in the show is now mostly limited to jokes concerning his incalculable age and pronounced frailty.
** The episode in Season 3 where Burns sells the power plant [[EarlyInstallmentWeirdness seems strange now]] because he seems to get along all right after he and Smithers part ways. Later episodes (e.g. "Homer the Smithers" in Season 7, "The Old Man and the Lisa" in Season 8) show him unable to function without Smithers as his assistant/caregiver.
* [[TheDitz Ralph Wiggum]] was originally just another generic classmate of Lisa's. He eventually became a childish, socially awkward kid who has HiddenDepths of brilliance (like when he turned out to be an excellent actor in the George Washington play or [[AchievementsInIgnorance when he won a diorama contest because he had collectible Star Wars action figures that Principal Skinner was trying to find all these years]]). Then he became incredibly dense (to the point that there are implications that he's a special ed. student) and frequently spouts non sequiturs, though "E. Pluribus Wiggum" showed that Ralph had a smart side, as he wanted to run for U.S. President because he wanted to bring about world peace. Heck, there used to be a trope ''named'' "The Ralph Wiggum" to describe characters as dumb as he[[note]]It was merged into TheDitz for being too similar to it. On twelve votes.[[/note]].
* Lisa started out as a sweet-natured, intelligent and very well-behaved little girl. She wasn't even that brilliant or mature in the early episodes (for example, she believes in Santa Claus and watches a cartoon that's basically ''TheSmurfs''), but she was clearly quite an achiever for her age. However, over time, she became Little Miss Perfect. Her intelligence was taken UpToEleven, with her doing things like trigonometry [[NotAllowedToGrowUp while still in second grade]] and understanding fractions in a flashback to when she was three years old. She started complaining about anything and everything that didn't meet her high standards. Her strong progressive streak became activist tendencies (as seen in "[[Recap/TheSimpsonsS5E14LisaVsMalibuStacy Lisa vs. Malibu Stacy]]," when she protested against the Talking Malibu Stacy's misogynist phrases like "Thinking too much gives you wrinkles" and "My name is Stacy, but you can call me (''(WolfWhistle)''), then full-out environmental and uber-liberal extremism (as seen in "[[Recap/TheSimpsonsS7E5LisaTheVegetarian Lisa the Vegetarian]]," "[[Recap/TheSimpsonsS8E21TheOldManAndTheLisa The Old Man and the Lisa]]," and "[[Recap/TheSimpsonsS12E4LisaTheTreeHugger Lisa the Treehugger]]"). Her sardonic view of society as uncultured, phony, pandering, and lowest-common-denominator-focused became extreme intellectual superiority and being HolierThanThou (as seen in "[[Recap/TheSimpsonsS10E22TheySavedLisasBrain They Saved Lisa's Brain]]") and her quirkiness and nerdy interests became patronizing enthusiasm for the most pretentious of vocations (as seen in "Elementary School Musical" and "The Day The Earth Stood Cool"). She went from being a model child and the voice of reason (and therefore, Bart's contrast) to a stuck-up genius prude.
* Marge went from being a loving, prepared, [[WomenAreWiser down to earth]] mother who lectured Bart whenever he was up to his old tricks to [[MeddlingParents overprotecting him and being paranoid about his well-being]]. Marge was also more forgiving of Homer early on. She loved him without question and would excuse some behaviour others wouldn't, but she'd also call him on his nonsense if he went too far. As Homer became Flanderized into a JerkAss idiot, Marge became more of a StepfordSmiler who knew that her husband did some crazy shit, but really wanted to stay with him because...well, because the writers don't want to show Homer and Marge divorced.
** Her somewhat no-nonsense personality was also Flanderized somewhat. In early episodes, she was merely [[WomenAreWiser wiser]] and something of a nag, though she ''did'' cut loose on several occasions. In later episodes she is extremely boring and un-impulsive by nature, getting hyped up by ''household chores and monotonous hobbies''.
** Marge and Lisa's Flanderization at least moderated Homer and Bart's however. While the former were usually the latter's Straight Men and thus in the "always right" to their "always wrong" role, their increasingly more self righteous and flawed zeal allowed moments of clarity from the two boys, and cases where their deranged fun loving personas were seen in a more harmless light. Compared to his earliest roles, while much more air headed, there are times Homer is treated as being right.
* Martin Prince used to be a natural leader, StrawWinner and no-nonsense kid student, with brains that were equally fit for science, sports or arts. However, as the seasons advanced, his interests on arts mushroomed into a plain effeminate personality, until he was practically turned into a flamboyant sissy and also another of the default nerdish {{Butt Monkey}}s of Springfield's Elementary.
* Milhouse Van Houten started out as a slightly awkward, smarter than average but gray and unpopular Bart's best friend. His unpopularity and bad luck were exaggerated until he became the default {{Butt Monkey}} and StrawLoser of Springfield's elementary. His personality changed later into making him extremely puny and childish in order to make him even more pathetic. His romantic interest in Lisa was a minor trait in the beginning, but then his sole purpose in life became trying to impress her.
** The writers apparently didn't know what to do with Milhouse for a while, because he went through a crazy phase and a sissy phase before he became the Lisa-obsessed dork he is today.
* Patty and Selma have gone from just making mean jokes about Homer being fat, ugly, and a lousy father and husband who should have never knocked up their baby sister (Marge) to kidnapping him and locking him in a dirty bathroom ''a la'' ''Saw'' (the first one).
** In earlier seasons, Patty was merely uninterested in dating, and actually had a serious relationship with Seymour Skinner before determining that she couldn't abandon Selma. Later in the series, her disinterest in men was exaggerated... to the point that she became a lesbian.
** At the same time, Selma was originally portrayed as a lonely singleton in her thirties, hoping to still find love. Later on her man-craziness and multiple failed marriages became a RunningGag, and she was married off to practically every single man in Springfield at some point or another, and always doomed for divorce.
* Moe started out as a simple bartender who was kind of cheap and surly, but was a generally okay person to be around. In later episodes, Moe is a serial criminal who actively revolted women (and it's been exaggerated to the point that he's now a registered sex offender). He's also often seen torching his own bar or paying someone to do something illegal and unethical, like having Homer steal and destroy his car, keeping an orca that he kidnapped from Sea World in his bar, or holding ''Deer Hunter''-style Russian Roulette games in his basement. It should be noted that the focus on Moe being a creepy pervert instead of a grump conveniently came only after ''WesternAnimation/FamilyGuy's'' Quagmire gained popularity.
** Where once he was content (if somewhat disappointed) with his low station in life, he's also developed chronic depressive tendencies, to the point that almost every modern appearance of his involves a botched suicide attempt.
* Bart simply started out as a 1990s version of DennisTheMenace who liked to piss off authority, but actually learned his lesson in the end, like when he stole Jebediah Springfield's head or when he burned Lisa's centerpiece and, after appearing on the news in a homeless shelter, returning home and apologizing for what he did after a soul search. These days, his negative qualities have been exaggerated to the point where he's a ''sociopath'' wanting to ruin Homer and Marge's marriage merely to get him out of homework (as seen in the episode "Postcards from the Wedge"). The only times Bart shows kindness to anyone are when the story demands it, as seen in "A Totally Fun Thing that Bart Will Never Do Again," in which, despite his sociopathic measures to make the cruise trip last longer, did it because he loved his family and wanted to see them be happy, as they never had a decent vacation where everyone was happy.
** Bart seems to have lost all empathy towards everyone, including his own family, if it means getting a quick laugh. When Homer is forced to go to a fathering class after accidentally making Bart pee in front of everyone when he was tickling him too much, he was forced to be strangled by Kareem Abdul-Jabbar to show what Bart experiences when he does that to him. When Homer vows not to strangle or physically punish Bart again, Bart milks it for all that it's worth. He does many blatantly illegal acts since he knows he won't be punished by Homer. He even tries to get his father ''killed'' during the bonding exercises. This was actually established all the way back in "The Itchy And Scratchy Movie". After Homer backs out from punishing Bart, he becomes increasingly rambunctious, destroying and causing mayhem in the house for reasons even he doesn't know outside that he can get away with it, smugly confident that Homer will let everything slide. As such, it was established as early as the Fourth Season that discipline is the only thing keeping Bart from acting like a complete sociopath.
** He endangers Principal Skinner's life with his peanut allergy, exploiting this to make Skinner do what he wanted. Bart is willing to ''threaten to kill'' someone just because [[ItAmusedMe the results amuse him]], though the joke was on Bart when Skinner fought back with knowledge of Bart's shrimp allergy[[note]]A SeriesContinuityError: In season two's "Blood Feud," Marge told Bart that he was allergic to butterscotch, imitation butterscotch, and glow-in-the-dark monster make-up, and some latter-day episodes, like "The Frying Game" and "Mommie Beerest" show Bart eating shrimp without any adverse effects[[/note]]
** Bart's intelligence also has dwindled down as much as Homer's. Bart started off as BrilliantButLazy to being unable to read basic sentences in books or relying on Lisa to do his school work for him due to being lazy and unintelligent. Due to Bart spending more time slacking off at school and playing pranks on the town, his dimmed intelligence is justified. This is best reflected in the "future" episodes. "Itchy and Scratchy: The Movie" and "[[Recap/TheSimpsonsS6E19LisasWedding Lisa's Wedding]]" imply that Bart will gradually outgrow his rebellious tendencies to eventually become Chief Justice of the Supreme Court (the title is actually "Chief Justice of the United States," but anyway), but all later depictions of his future [[FutureLoser imply that he'll never amount to much]].
** The writers have been trying to get rid of Bart's sociopathic characterization in recent years.
** For some reason, the writers have really loved writing romance plots for Bart and Lisa in recent seasons. Occasionally it's all well and good, but these characters are still canonically eight and ten years old, and Bart's been written as making out with a teenager!
* Similar to the WesternAnimation/FamilyGuy summation below, [[http://crazygirlmuses.tumblr.com/post/8150999695/idea-blatantly-lifted-from-here-yes-the-ironing this Tumblr image.]]
* Edna Krabappel has actually gone through reverse Flanderization. Her defining traits in the early episodes were that she [[ReallyGetsAround was a bit of a slut]], was a lonely, bitter divorcee, and was extremely apathetic and had no passion for her teaching job (though, you'd be that way too if your husband left you for "something small and fluffy down a rabbit hole" and you had someone like Bart Simpson as one of your students). After she married Ned, she became nothing more than "Ned Flanders' wife" until [[AuthorExistenceFailure her voice actress's death.]]
* Helen Lovejoy went from "the nagging wife of the pastor" to "[[GossipyHens a stuck up bitch who has to get the dirt on everyone, but mostly on Marge]]". She seems to exist to antagonize Marge for no reason other than [[ItAmusedMe because she can]].
* Otto went through the same process as Hermes on ''Futurama''. He was indicated to be a pot-smoker through occasional subtle jokes young viewers wouldn't pick up on. The drug jokes got more common and overt over time, and now seem to dominate his character. He went from being a laid-back bus driver the kids thought was cool to being a dangerous low-life who uses any and all illegal drugs.
** His love of heavy metal music was also Flanderized, with him selfishly cancelling his own wedding after his fiancée states that she dislikes heavy metal.
* Reverend Lovejoy, on the other hand, has HiddenDepths. His character has remained the same the entire series - however, one episode revealed that Lovejoy became a bitter, jaded, faux pious clergy because Ned drained all of his enthusiasm for serving God.
* Seymour Skinner was Flanderized very quickly. Early appearances had him mainly as a reasonably competent, no-nonsense principal who had been to Vietnam and had an overbearing mother. He even managed to be pretty badass in a few episodes ([[Recap/TheSimpsonsS5E20TheBoyWhoKnewTooMuch The Boy Who Knew Too Much]]). After a few seasons, he became a pathological mama's boy who was still a virgin in his 40s and merely embarrassed himself whenever he tried to assert authority over Bart or any other students.
* Lenny and Carl were originally ThoseTwoGuys that Homer worked with, who were both more competent than he was but liked Homer in a class-clown sort of way. Later in the series, they started being written as secretly gay, to the point where Lenny's defining character trait in later seasons is his (unevenly reciprocated) infatuation with Carl. Their intelligence also dimmed somewhat, making them more liable to join Homer in his antics.

[[folder:South Park]]
* Stan's father, Randy, started out as one of the smartest characters on the show. His 'wild side' stemmed from a desire to connect with his son, and he simply failed to grasp the idea of fads changing rapidly, a frequent plot point in ''South Park''. In later episodes, he became a hyperactive, extremely paranoid and idiotic ManChild.
** Adding to that, even within his earlier stupid bouts, he was still usually a KnightTemplarParent, genuinely having the best intentions for Stan and only spearheading the same hysteria the other parents succumbed to. From about Season Nine onwards however, Randy's motives became more selfish and childish, having his family in collateral damage for whatever fad he takes to and leaving even the other brain dead residents of South Park dumbfounded by his behavior.
* Cartman is an interesting case:
** In the early seasons, his anti-Semitic streak was relatively mild and was nothing more than making fun of Kyle not celebrating Christmas. Between Seasons 5 and 15, it is FAR more prominent, to the point where, in "The Passion Of The Jew", he tries to instigate his own Holocaust.
** That said, CharacterDevelopment arguably resulted in an inversion of this trope, too. Cartman has generally gotten more intelligent over the years. Originally, his selfish, impulsive behaviour stemmed from his absolute inability to think beyond his momentary desires. Now, however, he's usually running mental circles around Stan and Kyle and his evilness is premeditated, revealing him as an absolute villain. His whining used to only sway his mother and leave everybody else absolutely unmoved, but now he's a master of manipulation and can play huge crowds like a fiddle. Given that South Park has Flanderized its characters mainly to allow them to fit into the increasing "Plot of the Week" format, Cartman's role has often been repurposed to that of villain and instigator. In this format Kyle is almost always trying to combat his schemes, turning them from friends who rip on each other to mortal enemies.
* Kyle went from being the voice of reason and Cartman's contrast to a stuck-up genius prude and flak magnet, sometimes being almost as much of a ButtMonkey as Butters. His rivalry with Cartman also increased to the point where it took up B-plots (if not the whole plot) of episodes.
* Stan's [[OnlySaneMan maturity and intelligence over most of the adult cast]] has been exaggerated more in the show's run. Initially he was far more child-like and mean spirited. Compare the gang's treatment of [[ButtMonkey Butters]] in earlier and later seasons, for example. His cynicism and aggravation at others around him was also ramped up to the point where the episodes "You're Getting Old" and "Ass Burgers" [[BrokenBase created a sharp divide with fans]].
** He's also been increasingly involved in misguided escapades to the chagrin of Kyle, in a sort of fashion that disturbingly resembles him going down his [[InTheBlood father's]] [[TookALevelInDumbass path]]. This is attributable to his own increasing ({{W|angst}}){{angst}}, which just so happens to [[CerebusRetcon have been revealed as]] the cause of his father's Flanderization.
* Butters himself started out as one of the 'weird' kids but otherwise normal. Now he's an UnpopularPopularCharacter with occasional moments of brilliance. This Flanderization seems to have been slightly better received. However there are concerns that he risks becoming a DumbIsGood character if his naïvete increases.
* Wendy Testaburger used to be little more than a prepubescent HelloNurse character whose very appearance would cause Stan (who had a mild crush on her, but it was exaggerated in TheMovie) to vomit nervously, other than an episode that showed her to have dangerous jealous tendencies. Her intelligence and general competence, and her legitimacy as a character in her own right, have grown exponentially. In other words, she went from being just a normal, level-headed little girl to the most awesome person in the whole school, especially with her NoHoldsBarredBeatdown of Cartman (after he mocked her one too many times).
** She's also become the [[SoapboxSadie fervently outspoken]] de facto [[AuthorTract liberal mouthpiece]] for Trey and Matt, leaving Kyle as the primary deliverer of the show's more conservative messages.
* Butters' parents. When they first appeared, they grounded Butters for pulling a "goofy face" in his school picture because his hair was out of place. It was actually his normal face, but it was ''the school'' that thought otherwise and Butters' parents simply believed them. The first sign of the Flanderization occurs when they beat him mercilessly at the end of "Jared Has Aides." Afterwards, they seem to punish Butters for merely existing.
* Several characters have been flanderized in ''WesternAnimation/SouthParkBiggerLongerAndUncut'', mainly for plot reasons.
** Terrence and Phillip [[SirSwearsALot swear a lot more]] here than in the TV show.
** Sheila's {{Moral Guardian|s}} soapboxing evolved from mass protests to ''an actual war''.
* The show itself twice. The show started out as nothing more than WesternAnimation/{{Rugrats}} [[XMeetsY meets]] ComicStrip/{{Peanuts}} for an adult audience and had many plots focusing on the kids themselves, to the point of where the kids and the adults were as equally important to the show. However, by Season 5, the show had changed its tone to become more satirical and have much more of a mature atmosphere compared to the later seasons, satirizing a few current events and developing the characters.
** The show received a second Flanderization, much more severe than the first. When Bill Hader came onto the writing team in Season 12, all the characters were flanderized to act like teenagers, and the show began satirizing current events in every episode (Which has led to WereStillRelevantDammit plots). Not to mention that many characters that weren't flanderized before had received flanderization, and the show as a whole became much more mean-spirited. Not to mention that since Hader came on the team, the show has unexpectedly gained more teenagers as its audience (As opposed to the show's early years, where it was mostly popular with adults).
** The political element of the show can also be seen its casts' respective Flanderizations. Stan represents the reluctant-yet-noble moderate liberal side of the creators, with Kyle leaning more towards their moderate conservative end. Wendy is the voice of the militiantly pro-feminist/LGBT hard left, with Cartman resembling the {{politically incorrect|villain}} right-wing extremist [[GettingCrapPastTheRadar under the guise of]] {{Anti Villain}}y.
[[/folder]]

[[folder:Spongebob Squarepants]]
''WesternAnimation/SpongebobSquarepants'' has experienced massive flanderization since its [[UnCanceled un-cancellation]] in 2005.
* In the pre-cancellation episodes, SpongeBobSquarePants in many ways was like an underwater, sea-sponge version of Tommy Pickles from ''WesternAnimation/{{Rugrats}}''. The "earnest [[TheEveryman everyman]]" aspect of Spongebob's personality has been completely downplayed to make him gratuitously obnoxious and annoying rather than merely naive and [[{{Cloudcuckoolander}} eccentric]]. Now he's gone into ''stalker'' levels of creepiness when it comes to Squidward, copying his entire house ''down to the very last detail'' and heavily breathing whenever he calls.
** It's shown the most during his driving. When it's first revealed that he failed the test 38 times, it's apparently because he gets so damn nervous behind the wheel, he floors it, causing misery for Mrs. Puff and anyone else, DESPITE knowing everything (something that is actually a bit realistic). Now? He's a GiftedlyBad driver who puts everyone in danger behind the wheel to the point where he's a [[PersonOfMassDestruction Sponge of Mass Destruction]].
** Let's not forget of course that the number of driving tests he's failed was bumped up from 38 times (from the first season) to ''over a million'' later on; even the plot details have suffered a strange combination of Flanderization and Retcon.
* Patrick went from an oddball who was slightly slow on the uptake (he even helped Spongebob almost pass his boating test for the first time ever through radio), [[TookALevelInDumbass to one of the]] [[TheDitz dumbest characters on television]]. Recent seasons have also made Patrick [[TookALevelInJerkass take multiple levels of jerkassery]] up to FatBastard territory, going by the way he treats Spongebob and Squidward on several occasions. His stupidity was actually Flanderized ''before'' the cancellation, to the point where he forgets that he ate a chocolate bar immediately after doing so, even saying the exact same thing and biting his hand, but back then nobody minded because his antics were still funny. After the revival though, the humor is gone, so his idiocy ''causes'' his jerkass Flanderization.
* Mr. Krabs went from being a typical [[PointyHairedBoss greedy yet usually well-intentioned boss]] to being borderline FauxAffablyEvil with an over-exaggerated MoneyFetish who would go through several kinds of hell just to retrieve a ''single penny''. One newer episode portrayed him as more obsessed with money as an ''object'' rather than for its value. While his greed was always prominent, he at least had some feasible redeeming aspects and morals to balance it out, his fatherly role with Spongebob and Pearl for example. In later episodes, aside from some {{Jerkass}} qualities, his money-lust seems to be his sole defining trait, thus it is a pretty valid example of Flanderization, albeit DependingOnTheWriter admittedly. It's also worthwhile noting that in earlier seasons, Krabs [[LaserGuidedKarma usually did receive his comeuppance]] every now and then with his ([[MoralEventHorizon sometimes morally questionable]]) schemes. In later seasons, this is the total opposite -- Krabs is practically KarmaHoudini ''incarnate,'' considering that he somehow gets away scot-free with anything he does nowadays (ranging from theft to poisoning his customers to even ''driving people to suicide''), sometimes leaving someone to take the blame/pay the price. There are even times near the end of some episodes when it looks like Krabs is about to receive his comeuppance (or in rare cases, actually ''does''), but something happens at the end that puts the situation in Krabs's favor, if not lets him escape punishment entirely.
* Squidward's ButtMonkey role was transformed from mere LaserGuidedKarma to a mix of outright ComedicSociopathy and KafkaKomedy, with nearly every entity in Bikini Bottom genuinely out to make him miserable. This could arguably be considered a skewed form of CharacterDevelopment since it made his {{Jerkass}} (admittedly with a [[JerkWithAHeartOfGold Heart of Gold]]) demeanor far more justified. Squidward's hatred of Spongebob has also been flanderized, though. For example, in one of the early-season Christmas specials, he gives away everything he owns so that Spongebob won't cry. In a later-season episode, when Spongebob bursts into tears after Squidward convinces him that he can no longer laugh or smile again, Squidward just walks away with a smirk, saying "Oh, I hate it when he's sad. But I hate it even MORE when he's happy".
* Sandy, originally a science geek with OnlySaneMan tendencies, eventually gained a self-awareness of her [[ParodySue many talents]] and evolved into a rowdy Ted Baxter. They've also completely phased out her Texas Cowgirl tendencies for her scientist role, despite that her inventor traits were almost mute over the first few seasons.
* Plankton's IneffectualSympatheticVillain role, to the point where he is arguably more likeable than [[DesignatedHero his nemesis]]. His [[AIIsACrapshoot sentient computer 'wife']], Karen's DeadpanSnarker mannerisms have also been upped to eleven.
* Originally, Mrs. Puff was just a NoRespectGuy who didn't want to have to deal with Spongebob's bad driving. Then she tried to ''murder'' Spongebob...
* The show itself. As its own page says, it turned from a relatively conventional kid's show with slight GrossOutShow and GagSeries to a BlackComedy SadistShow GagSeries that involves [[CrapsackWorld apocalyptically retarded/mean characters]] in surreal situations in a show that [[CrossesTheLineTwice wouldn't be out of place in]] Creator/CartoonNetwork's Creator/AdultSwim lineup. It's safe to say that not a single TV show ''in general'' (except ''WesternAnimation/FamilyGuy'') could change as much this show.
** Which actually makes sense if you consider ''WesternAnimation/TheSpongebobSquarepantsMovie'' to be the ending (Which it was until Nickelodeon did some ExecutiveMeddling and forced the producers to uncancel the show). If you compare the movie to the pre-movie episodes you find that a lot of things don't make sense, such as Spongebob considered a "kid" when in Pre Revival episodes he appears to be somewhat childish but a well-likable person, yet everyone in Bikini Bottom called him an asshole ("A goofball, a wingnut and a KNUCKLE-HEAD [=McSpazitron=]!"), also the Pre-cancellation Plankton doesn't seem like he'll go overboard and MIND CONTROL EVERYONE in BIKINI BOTTOM and KILL HIS RIVAL (sure they hate each other in the business department but doesn't seem like they would kill each other). Then the post-movie episodes come out and slowly but surely we see the events that lead up to the movie. As Mr. Krabs becomes more greedy and crosses the MoralEventHorizon Plankton snaps from an AffablyEvil PunchClockVillain to an AxCrazy [[TheChessmaster Chessmaster]] in order to get back at Mr. Krabs, while everyone in Bikini Bottom becomes sick of Spongebob's ridiculous, often cataclysmic antics.
[[/folder]]

[[folder:Other cartoons]]
* Roger's affinity for costumes and dress up acts in ''WesternAnimation/AmericanDad'', to the point some [[BecomingTheMask take over]] [[FunnySchizophrenia his personality]]. His Jerkass traits also initially just came with [[{{Cloudcuckoolander}} the quirkiness]] of his personality and were much more toned down. As time progressed, his callousness is canonically accepted as his defining trait (to the point [[InTheBlood he'll actually die]] [[ThePowerOfHate without acting consistantly cruel]]). Most of his complexities from early episodes such as his loneliness and the fact he is an ''extra terrestrial'' are barely referred to in favor of making him essentially a cross-dressing version of [[WesternAnimation/FamilyGuy Peter Griffin]].
** This seems to be downplayed in the last season of the original run on FOX, as Roger is hardly shown and is seen joining in for the most part with the other characters and acting less like a sociopath.
*** Klaus, while somewhat pitiful at first due to his transformation, was more upbeat and quite the Jerkass at times. As episodes progressed, his depression and loneliness kicked in more and more, along with becoming more and more a consistant ButtMonkey from the Smith's neglect and abuse. However, it should be noted he is still treated with a lot more respect and dignity by the family, the writers and the fans in comparison to say, Meg from Family Guy.
**** A big part of Klaus's character in early seasons was his sexual obsession with Francine, which has completely vanished over time. Two particular episodes seem to indicate where Klaus gave up and where Francine started disliking him: "Finances with Wolves", where Klaus gets a human body and tries to seduce Francine (and she finds out) and "Big Trouble in Little Langley" where Francine commits SnubByOmission after the house catches fire and, when she tries to correct her mistake, is told by an angry Klaus "Too fucking late." Admittedly this may have been for the best, as before then he was, like Roger above, a German version of Brian Griffin.
** Early episodes have brief scenes that imply Principal Lewis had a checkered past, but overall he was shown as a responsible and respectable educator. Later episodes make him a wildly irresponsible drug addict who could never behave in an appropriate manner, even around students. Some see it as a good thing, as he was a fairly generic character. Lampshaded in one episode post-Flanderization where Steve outright says "I have a hard time believing you're an educator, Brian."
** Steve's obsession with losing his virginity.
** Hayley seems to have suffered an almost reverse-Flanderization: In the beginning, she was always expressing her leftist views; as the series went on, she was seen less and less, and when she was seen, she would just be used to deliver exposition, or as the butt of jokes with her husband Jeff.
** Stan was always something of a bumbling sociopath, but it originated more from his ego and right wing extremities, and at times he diverged from Creator/SethMacfarlane's traditional BumblingDad role by proving to have HiddenDepths and some amount of tact (to the point of having spaced moments he was actually ''right'' about something). As time passed however, the necessity for Stan to learn AnAesop [[AesopAmnesia every episode]] led to him becoming increasingly moronic and childish, and his Badass CIA agent qualities have been increasingly degraded in favor of making him a borderline StrawLoser for the rest of the Smiths. Basically Stan evolved from a slightly smarter right wing Peter Griffin to just being another Peter Griffin.
* Haley Long in ''WesternAnimation/AmericanDragonJakeLong'' went from being a slightly above average intelligence, slightly precocious, generally well behaved 8 year old girl in season 1, to an absolute ChildProdigy AttentionWhore AnnoyingYoungerSibling who loves rubbing her brother's nose in her achievements by season 2. She also has almost physical revulsion to the idea of misbehavior in season 2 whereas by contrast in season 1 she didn't bat a eye lid at sneaking out with Jake to go to a rock concert.
* The characters in ''WesternAnimation/AnAmericanTail'' don't get ''too'' flanderized in the movies, except maybe for Tiger becoming a dim-witted coward throughout the sequels, but this may be forgiven because he wasn't given much screentime to develop in the first movie. However in the TV series ''Fievel's American Tails'', flanderization affects nearly all of the characters. Fievel's fascination with the wild west becomes a complete obsession that nearly defines his entire character, Tiger becomes cowardly and a [[TheDitz complete imbecile]] (amped up much further than in any of the movies), Cat R. Waul goes from being AffablyEvil to the IneffectualSympatheticVillain, the list goes on.
* Norbert and Daggett of ''WesternAnimation/TheAngryBeavers''. Daggett was always the less intelligent of the two, even in season 1, but he still sometimes had moments of brilliance such as in the episode Bug-A-Boo, or Euro Beavers. However, by the show's final season, Daggett devolved into a complete hulking moron. In the episode The Loogie Hawk, he can't even locate the elusive hawk even after reading a sign that says, "LOOGIE HAWK: RIGHT THIS WAY". Norbert, on the other hand, being [[BigBrotherBully the older brother]] regularly picked on Daggett throughout the series, [[VitriolicBestBuds but usually in a playful way]]. By season 5, Norb had become downright MEAN towards Dag. In the episode Specs Appeal, he actually cons Dag out of his own money, even though Norb has his own stash of BILLIONS OF DOLLARS in a secret vault!
* In the first half of Season 1 of ''WesternAnimation/{{Archer}}'' Cheryl goes from being unstable and mildly neurotic to insane and psychopathic. She's actually funnier and more endearing post-Flanderization, [[TropesAreTools in a rare positive example.]]
** Another positive example happened with Pam: she goes from complete lonely and pathetic sad sack to the biggest badass in the cast.
** ISIS itself was Flanderized: in early seasons, they were a somewhat dysfunctional but still competent organization. As the series progressed, they became a full blown IncompetenceInc with all their missions ending in complete failure and resorting to increasingly harebrained schemes to stay afloat.
* Several of the characters from ''WesternAnimation/{{Barnyard}}'' were flanderized for the sake of comedy in the [[RecycledTheSeries series adaptation]] ''WesternAnimation/BackAtTheBarnyard''. The most notable is Otis, who went from the {{badass}} leader of the gang [[SugarWiki/MomentOfAwesome who beat up a bunch of coyotes to rescue the chickens they kidnapped and]] [[YouKilledMyFather avenge his father who they killed]], to both a coward and a moron who has difficulty writing his own name. There's also Freddy, whose attempts to suppress his ferret urges to eat his best friend Peck (a chicken) were exaggerated, and Mrs. Beady, who became a nut job obsessed with revealing the animals' anthropomorphism to the world, though in the case of the latter it's definitely TropesAreNotBad.
* ''WesternAnimation/BatmanTheAnimatedSeries'': Somewhere between the early seasons and the later "new look" seasons, Batman went from a caring and compassionate man with some anger issues to the mostly cold grim vigilante most people recognize. It works mostly (unless he goes the full Jerkass route) but its a bit odd when you're rewatching the series. Some of the villains go from conflicted neurotics who seemed like they could be saved to simpler hardened criminals although this is usually justified as them giving up on a normal life after failed attempts at reform. This could be attributed to the growing number of youthful, idealistic foils introduced by ExecutiveMeddling. The higher-ups became increasingly convinced that Batman was too old for the TargetAudience to relate to, hence the addition of Robin, Batgirl, the other Robin and very nearly Creeper. Some of Batman's worst Jerkass moments resulted from his use as a foil for the sidekicks, as seen in the episodes "Old Wounds", "Never Fear" and "Growing Pains". This had the effect of making Batman considerably less likable and, ironically, less relatable, although it worked in ''WesternAnimation/BatmanBeyond'' when he was 80. It's at least justified for "Never Fear" considering Batman was [[NotHimself under the effects of]] Scarecrow's gas.
** The animated portrayals of the villains remained more or less stable throughout the series' run, with two notable exceptions.
*** The Ventriloquist was always a milquetoast sissy-boy [[LetsGetDangerous who could still be quite dangerous when the situation demanded it]], but every time he appeared his wimpiness only seemed to increase until his puppet, Scarface, had virtually taken control of ''him''. Eventually he became so frightened of Scarface that he was constantly trying to ''hide from him'' (from a wooden dummy!). Somewhat justified by the fact that he's ''constantly'' being put down by Scarface, and so its understandable his confidence would dwindle by the constant bullying until he became completely docile; this trajectory finally resulted in the Ventriloquist's HeelFaceTurn, so maybe it was just CharacterDevelopment.
*** The Mad Hatter started out a quite menacing and fairly serious villain (at least by the standards of the show). He did grow more dangerous as time went on - but unfortunately he also got sillier, so that by the end of the series he was a ridiculous (if still sadistic) fruitcake constantly spouting Joker-like puns. He also physically shrunk, so in his last episode he looks barely taller than an Ewok!
* The entire Franchise/{{DCAU}} could count. With the aforementioned ''WesternAnimation/BatmanTheAnimatedSeries'', it starts off as a more representative portrayal of the original comics, but beginning with ''WesternAnimation/SupermanTheAnimatedSeries'', is later flanderized gradually into a {{Deconstruction}} of previous portrayals (including said original comics).
* In ''Franchise/{{Transformers}}: WesternAnimation/BeastWars'', Silverbolt began as an idealistic, over-the-top [[KnightInShiningArmor Paladin-type who followed chivalry and loyalty]] to often comedic extremes. His relationship with Blackarachnia nearly took over his character by the third season, though it was written with some level of competency. More egregious is Blackarachnia's overnight transformation from DarkActionGirl who, oh, had a boyfriend into a romantic who would stop at nothing, including disloyalty and [[WhatWereYouThinking downright foolishness]] to get her lover back in ''Beast Machines''. For that matter ''everybody'' in ''Beast Machines'' underwent some Flanderization as compared to ''Beast Wars''.
* And speaking of things involving Creator/MikeJudge, ''WesternAnimation/BeavisAndButtHead'' started out as immature, {{Jerkass}}, not-particularly-bright teenage delinquents. Eventually the "not particularly bright" part of their characters consumed them--Beavis became TheDitz, while Butt-head was only TheSmartGuy compared to Beavis. They both go through life completely oblivious to the world around them and ignore important things said to them to [[HehHehYouSaidX point out sexual innuendoes]]. This [[TropesAreTools made them much funnier.]]. In the revival, there's a case of a De-Flanderized trait. Beavis & Butt-Head while their stupidity remains, are geniunely seen as smarter & more self aware of the world.
** The 2011 revival, however, did have one Flanderisation; B&B's {{metalhead}} roots have been downplayed a lot. While the original incarnations were prone to burst into random AirGuitar sessions at times, the newer incarnations do not go far beyond the AC/DC and Metallica shirts they wear. However, this is pretty much justified by comparing how relevant HeavyMetal was in 1993 against 2011.
* ''WesternAnimation/{{Ben 10}}'' has an unusual case of an inanimate object being flanderized over the course of the show's run. The Omnitrix's tendency to turn Ben into the wrong alien or time out at exactly the wrong moment is slowly exaggerated over the course of the show's run; in early episodes, it's fairly reliable, only doing this once every few episodes, with the implication being that Ben's inexperience with and ignorance of [[ImportedAlienPhlebotinum a mysterious and complex alien device]] is the culprit. In later seasons, the watch screws him over so many times in a single episode that one can't help but wonder if it hasn't developed both sentience and a malicious sense of humor. It could even be a case of FridgeBrilliance if the device has indeed gained a mind of its own. The Omnitrix could be subtly training him, thinking "Yes, I'm sure that powerset would be the perfect way to get you out of this mess. However, let's see how creative you can be if I instead, hand you ''this'' powerset." Doesn't hurt for Ben to not become too set in his ways of thinking how to use these powers, after all.
** In the first two seasons of ''[[WesternAnimation/Ben10AlienForce Alien Force]]'', Gwen was initially a calm, soft-spoken and responsible person who is less snarky, but has occasional {{Tsundere}} outbursts. By the third season onwards she more consistently acts as an sternly serious, moody, headstrong, hot-headed, stubborn, snarky and occasionally aggressive teenager who becomes easily irritated.
** Kevin changed a lot with time. At first he was a kid deliquent that stole Ben's powers but then, by Alien Force, he becomes completely the opposite. He is overly responsible after recovering from his dark past, falls in love with Gwen on the first scene and is ready to give his life for any minimal chance to help Ben find his grandpa. In other words, he became a very nice dude, trying to be with the good guys and become a plumber. This of course, is all forgotten by season 3. Right on the first episode Kevin tries to hack the omnitrix (both he and Ben should've known better), he keeps self-loathing about his form and blames it on Gwen, and he sells weapons on war and never tells Ben and Gwen about it.
*** Even his Omniverse version got flanderized. Kevin loves cars but here is just ridiculous, he talks about machines and cars almost the time. He even agrees to marry a female Four Arms princess just to get the perfect engine for his car.
** Ben himself was Flanderized in an ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]'' episode where his ten year old self appeared. Somehow, Ben as a ten-year-old is even less well behaved than the Ben from Ben 10.
** Indeed, in later episodes of ''Ultimate Alien'', his teenage self has turned into a BrilliantButLazy, AttentionWhore, ItsAllAboutMe {{Jerkass}}, who only gets serious in the last ten minutes of the episode.
** Amazingly, ''WesternAnimation/Ben10Omniverse'' put it even further by flanderizing his ten years old incarnation ''again''. Ben from the original show was an immature brat, sure, but he would get serious when actual danger showed up, and show a more mature, softer side on occasion. This show portrays him in the flashbacks as obnoxious, bumbling and [[UpToEleven even more]] of a {{Jerkass}} than he was in ''Ultimate Alien''.
*** ''Omniverse'' has slowly pushed Ben out of the flanderizing traits he developed in ''Ultimate Alien,'' as evidenced with the episode "Malefactor." Ben used to be all about fame, but here, he calls out a fan for not realizing that his job involves a very real sense of danger.
*** This sadly wasn't permanent; in later episodes, his flanderization comes back especially in the third story arc: he neglects the danger represented by ''his own ArchEnemy'' in "Vilgax Must Croak", starts acting cocky again, and his CharacterRerailment is generally undone. Even the Omnitrix is flanderized further when it turns out it has ''an entire function'' to cause Ben to turn randomly into various aliens without any control.
* Panini from ''WesternAnimation/{{Chowder}}'' -- yeah, you wouldn't think it judging from the short run, but... compare her actions towards Chowder in "Chowder's Girlfriend", where she was just simply clingy and overeager about her love, to the 2nd season episode "Panini for President", where she practically goes ''[[{{Yandere}} insane]]'' and flatout admits that she wanted to be president so she can pass laws making Chowder "her property." This is lampshaded by Panini saying "I need a new hobby." after being rejected by Chowder in an episode. In her first appearance, she actually REJECTS Chowder when he asks her out, saying that "I need my space." Yet the Panini seen in later episodes seems determined to be around Chowder at all times.
** Chowder himself too, having transformed from a typical naive little boy to a flat-out dumbass.
* ''WesternAnimation/CloudyWithAChanceOfMeatballs'': Baby/Chicken Brent has the catchphrase of "Uh-oh" from his time as the mascot of the Baby Brent Sardine company. In the first film, he says it pretty often. The sequel, on the other hand, he says it so much it's reached VerbalTic levels.
* ''WesternAnimation/CodenameKidsNextDoor'' Flanderizes several characters.
** Numbuh Three (Kuki Sanban)'s ditziness. Originally, she was at least as useful as the others (albiet scatterbrained), but soon became a hyperactive ditz who's only usefull when Rainbow Monkey dolls are the case.
** Numbuh Four's stupidity. Originally, he was actually somewhat smart, he'd only lose control of himself when angry or afraid, such as in "Operation P.I.A.N.O." or "Operation L.I.C.E.". By the second season, he's become so stupid that however he even managed to get past second grade is a mystery. ''Painfully'' obvious if you've seen the first few seasons of the show, in which he was slow-witted and aggressive, but not dumb, and a pretty decent fighter. As the series went on, he can't even ''spell'' now and his "[[TheWorfEffect fighting skills]]'' are all an InformedAbility. [[spoiler: It was thankfully reverted in the DistantFinale where he's a very successful doctor]].
** Numbuh Five went from the OnlySaneMan into a borderline CanonSue in a really ridiculous case of PositiveDiscrimination.
* Katz from ''WesternAnimation/CourageTheCowardlyDog'' is an odd example. In his early appearances ("A Night at the Katz Motel" and "Klub Katz") his evil misdeeds were completely ForTheEvulz and certainly came to be disturbing and solidly creepy, but later, with attempts to kill people certainly had reason to do so, and indeed in "Ball of Revenge" seems to have become a little more affable to ally with his old foe Eustace to eliminate Courage.
* While there were a few characters in ''WesternAnimation/{{Daria}}'' who had this happen, the two most notable were probably Jake Morgendorffer and Tiffany Blum-Deckler. Jake went from being an ineffectual, easily-confused father with clear family issues to being an obsessive, infantile rageaholic {{Cloudcuckoolander}} and the show's ButtMonkey. Tiffany, conversely, was initially portrayed as being a somewhat narcissistic yes-woman to either Sandi or Quinn, depending on which one she was speaking to at the time. By the time the third season came around, though, her self-absorbed nature and incredibly slow speech patterns has developed to the point where it's a miracle that she's even made it through elementary school without having to repeat a few grades.
** Also subverted by the arc of Stacy Rowe, where her insecurity and panicky nature was ''initially'' Flanderized, but then over the course of the fifth season and series finale gained enough self-confidence that she became capable of standing up for herself and making her own decisions.
** This was ''invoked'' in the episode "Psycho Therapy", where everyone is asked to imitate each other.
** Ms. Barch (the man-hating science teacher) is an odd case. On the one hand, her simple hatred of men was Flanderized in later episodes to the point that she has used violence against her students and coworkers. On the other hand, she doesn't hate all men as she did in the early episodes. As of "The Daria Hunter" (from season two), Mr. O'Neill is the only man she loves (and brutally makes out with), even forgiving him when she sees him hold onto the waist of another woman (as seen in "Just Add Water"), abandoning her in the woods ("Anti-Social Climbers"), and falling for his allegedly assertive side after Mr. O'Neill is forced to break off his engagement to her ("Is It College Yet?")
** Also visible with the friendship between Quinn and Sandi. Originally, the two were somewhat friends (though any viewer could sense the slight animosity behind their [[PassiveAggressiveKombat "friendly" compliments]]). by season two, Sandi begins to try to sabotage Quinn for no other reason but jealousy. In season three, she begins to succeed, but Quinn remains popular. In season four, the two's rivalry has reached a boiling point, to the point the two have nightmares about the other cutting and ruining each other's hair. Could count as character development, however, and the two become closer in season five (somewhat).
* Mandark of ''WesternAnimation/DextersLaboratory'' in the post-finale seasons was pretty much ''defined'' by his hamminess and crush on Dee-Dee.
* The ''entire cast'' of ''WesternAnimation/DrawnTogether'', especially Princess Clara. One could argue that this was [[InvokedTrope on purpose]].
** Toot was originally the show's "bitch", but as time went on and she kept being called "fat", Toot actually gained more and more sympathy, eventually becoming an UnpopularPopularCharacter.
** Meanwhile, Princess Clara completely took over Toot's previous role. Originally starting off as a kind hearted, easily lovable, yet naive, and unintentionally racist and homophobic Franchise/DisneyPrincess to a cruel, god-fearing AlphaBitch who flaunts her beauty every chance she gets and a outright KnightTemplar [[TheFundamentalist fundamentalist christian]].
** Spanky evolves from being a malicious, greedy sadist to a mischievous party animal whose worst antics are defecating on pizza.
** Captain Hero went from a respected SuperHero with closeted gay tendencies and a frat boy personality to a completely disrespected loser who considers having sex with dead bodies better than coming out of the closet.
** Foxxy went from being a mystery solving hot chick who would occasionally display humorous racial stereotypes to the token who represented every black stereotype in the book.
* Zigzagged for Rufus and Amberley of ''WesternAnimation/TheDreamstone'', who started off with distinctive wackier personas (CloudCuckooLander and short fused AdorablyPrecociousChild respectively) in the pilot episode. Episodes after downplayed almost all their slapstick qualities, their personalities diluted into sometimes interchangeable {{Cheerful Child}}ren. The later half of the series started to revert them back however.
** Rufus' incompetence in particular took a steep turn. In the pilot and some Season One episodes, he was a dippy but occasionally brilliant character. As time passed, his positive traits were quickly outshone by the other heroes, who were all more powerful and intelligent than him, thus by Season Two, he was near solely TheLoad, constantly getting the stone lost (which only happened once in Season One) and prone to doing and saying the wrong thing so [[WomenAreWiser Amberley]] or another could rebuke him. He gradually reverted back come Season Three, and by Season Four he is more or less back to his old characterization. Amberley suffered a similar evolution, though at least managed to look better against Rufus.
** In addition, their contempt for [[TrappedInVillainy the Urpneys]] (which was originally more just self defensive apathy in the pilot) got exaggerated to relentless UnscrupulousHero levels, with them frequently taking much more sadistic pleasure tormenting the Urpneys [[DisproportionateRetribution far beyond the means of defense]] than [[PragmaticVillainy vise versa]]. This reached it's lowest point in "The Dream Beam Invasion" where they border MilesGloriosus bullies who back cowardly from their usual onslaught the moment the Urpneys become even slightly threatening, [[ATasteOfDefeat thus costing them a victory]]. After that, the writers seemed to get the point and similarly reverted things back.
** Zordrak was simplified almost entirely to just his angry BadBoss facets by Season Two, losing all his former competence and involvement and [[OrcusOnHisThrone usually limited to one or two scenes growling at the Urpneys to hurry up getting the stone for him]].
** In contrast, The Dream Maker's BigGood qualities took over his personality, turning from a wise, kindly but somewhat crotchety and befuddled old wizard to a pious embodiment of good between the first and second season. The extent of his magic powers, though [[StrongAsTheyNeedToBe always fluctuating according to the plot]], also became more [[InvincibleHero god like]] and [[DeusExMachina plot breaking]] as episodes passed.
** Frizz and Nug, originally interchangeable dimwitted {{Cowardly Sidekick}}s in the pilot, got Flanderized to one different facet as part of their DivergentCharacterEvolution. Frizz became more cowardly and neurotic, while Nug became more dopey and vacuous. {{Hidden Depths}} prevented the trope oversimplifying their personalities however.
* ''WesternAnimation/DuckTales'' has an in-universe case. When Scrooge winds up getting amnesia and going missing, Fenton attempts to pose as him to prevent his boss from losing a business deal regarding selling one of his factories. The only problem is, Fenton's portrayal of him is incredibly exaggerated: he's such a penny pincher ''the first thing he does is cut the allowance he gives the nephews.'' The real Scrooge has wound up getting a job at said factory and eventually winds up organizing a strike for the other workers. By the time he recovers his memory, Fenton's overly stingy version of him opens his eyes to some of his more rotten characteristics.
* On ''WesternAnimation/EdEddNEddy'', Ed went from a somewhat dim oaf with a love of comic books and horror movies to a non-sequitur-spouting [[TheDitz Ditz]] who seems unable to differentiate fantasy from reality, Edd went from a somewhat obsessively organized boy genius who was the voice of reason protesting Eddy's crazier schemes to a borderline hypochondriac goody-two-shoes, and Eddy lost most of the "loveable" part of his LoveableRogue personality and became more violent, manic, and surly. Again, that just covers the main characters.
** The episode "All Eds Are Off!" had this exaggerated and/or played for laughs. The Eds, Kevin, Rolf and Jonny gave up their flanderized habits:
*** '''Ed''': Obsession with gravy.
*** '''Edd''': [[SesquipedalianLoquaciousness Vast vocabulary.]]
*** '''Eddy''': [[NoIndoorVoice SHOUTING REALLY LOUD!!!]]
*** '''Kevin''': Using the word "dorks".
*** '''Rolf''': Eating meat. Plus, he's a [[{{Ruritania}} probably European]] [[FunnyForeigner immigrant with peculiar customs]], such as having furniture made entirely of meat, saying non-sequitur stuff supposed to be folk wisdom, etc.
*** '''Jonny''': Taking Plank's advice.
** The "Truth or Dare" episode had in-universe Flanderization done by the Ed's when they were dared to act like each other. Ed lampshades this when commenting on Double D's impersonation of him.
-->Edd (pretending to be Ed): Gravy!
-->Ed: Come on Double D I don't say "gravy" ''all'' the time.
-->Edd: Buttered toast then!
** While Jimmy was never all that masculine (he's just a kid whose best friend is a girl), he became borderline CampGay by the end of the series.
** During the first season, Jonny 2x4 was the slightly eccentric TagalongKid with his very own CompanionCube for a best friend who was an ally of The Eds, despite [[TheFool how they treated him.]] Come season two, he became [[CloudCuckoolander an annoying, oddball loudmouth]] and a saboteur how all the kids now were disliked and who almost solely would not act or even function without Plank's imput and presence. This is even [[LampshadeHanging lampshaded]] in the episode "Shoo Ed" and TheMovie, where by the end of the film [[spoiler: apparently ''he'' is now the odd kid out and decides to become [[FaceHeelTurn the villain of the show.]] Fortunately, the show is over by then.]]
** [[MsFanservice Nazz]] was known as the blonde, pretty girl who all the boys liked and who threw good parties in the first two seasons...[[FlatCharacter and nothing else.]] Come season three, she devolved into the stereotypical DumbBlonde and [[TheCheerleader cheerleader]] type who was still pretty and liked by the boys but would also spout one-liners or make "deep" observations that [[WhatAnIdiot seemed to defy all logic.]]
* In the PilotMovie for ''WesternAnimation/FostersHomeForImaginaryFriends'', Bloo was only slightly mischievous. As the series had progressed, some fans have complained that Bloo had became progressively more anarchic, selfish, and obnoxious, reaching {{Jerkass}} levels in later seasons.
** As well as Wilt being changed from an overly polite but perfectly sane and approachable nice guy to a [[TheWoobie total neurotic who's about five seconds away from a nervous breakdown,]] Edwardo going from a mere scaredy cat who can still stand up for himself at times to an extreme {{Cloudcuckoolander}}, and Herriman changing from the usual "uptight British butler" to a sadist. And that's not even getting into his [[GRatedDrug carrot addiction...]]
** Cheese went from "four-year-old with special needs" to "barely sentient baby" by his ''second'' appearance.
* Shipwreck from ''WesternAnimation/GIJoeARealAmericanHero'' was originally a confident sailor with a DeadpanSnarker side. Though he did have a lazy (and occasionally bumbling) side, he also cared deeply about the Joe team and stopping Cobra, while his emotional side could be seen in episodes like Memories of Mara and There's No Place like Springfield. By Season 2 though, he became completely incompetent and his laziness became his main trait (in one episode it was stated that he had no ambition or ability, by Hawk of all people).
* Arnold from ''WesternAnimation/HeyArnold'' was conspicuously Flanderized toward the end of the series. In the beginning of the series, he was an honest but down-to-earth, regular kid who did the right thing at the end despite sometimes letting himself get carried away occasionally (sometimes even to the point of being a Jerkass briefly, just like regular children). However, in later seasons he becomes a completely incorruptible real-life incarnation of Confucius (and possibly a fortune cookie), whose friends always consult his deep ethical wisdom in whatever subject was discussed and was willing to "do the right thing" no matter what the consequences would bring. Rather than being just another one of the neighborhood kids, he became the ultimate source for all children for advice, practically raising him into Jesus status with his deep, analytical advice and extreme consideration for ethics. The fact that this is a 4th grader we're talking about makes his Flanderization all the more blatant.
* WesternAnimation/InspectorGadget, mainly his intelligence. It's different in each episode. For example, he's smarter than usual in "Haunted Castle". And his main problem in "The Boat", where he actually almost pulled off an ObfuscatingStupidity-esque stunt but got caught at the last second, was that he suspected EVERYONE and thus didn't find the real bad guys in time. But the trend is as follows: He started off as InspectorOblivious, then progressed to TheDitz. His pride and vanity are exaggerated as the series progresses, too. Gadget's stupidity and obliviousness were taken UpToEleven where spin-offs like ''WesternAnimation/GadgetAndTheGadgetinis'' were concerned.
* ''WesternAnimation/InvaderZim''
** Gaz was originally just a CreepyChild who would occasionally act overly-dramatic over minor inconveniences: for example, in the first episode she declares that her brother "will pay!" for drinking the last soda, but then gets some orange juice and acts perfectly calm when he enters the room a moment later. Later episodes make her far more violent, beating him up numerous times for perceived slights. And that's not even going into how creepy the fanfiction can make her.
** Also Dib, who was always something of the StraightMan (at least compared to Zim) but who still seemed a bit manic and gullible in early episodes. By the end he seemed far saner (though still a bit naive), as well as far less optimistic that anyone will ever believe him about Zim. Arguably counts as CharacterDevelopment, however, since a lot of this would fit with his experiences fighting Zim throughout the series. As well as Dib's (an everyone else's) awareness/obsession/neurosis about the size of his head.
* While the jokes at the beginning of the series focused on his machismo and subsequent inability to attract women, Johnny's stupidity and immaturity were greatly exaggerated in seasons two and three of ''WesternAnimation/JohnnyBravo'', to the point where he was even classified as the village idiot by his peers in at least one episode. These elements were downplayed after Van Partible (the show's creator who was absent during those seasons) came back onto the show's staff, and Johnny was returned to his more well-adjusted season 1 personality.
* Allison "Allie" Underhill's {{Tsundere}} traits in ''WesternAnimation/{{Kaijudo}}''. Initially, Allie was simply a [[SpoiledSweet sweet rich girl]], but with an occasionally haughty attitude. By the second season, she becomes more consistently short-tempered and moody towards Ray, getting in arguements with him, endangering their friendship.
* ''WesternAnimation/KimPossible''
** [[HarmlessVillain Dr. Drakken]] was introduced in the first season as a super villain underdog who, despite some quirks, was threatening to the world and Kim. From Season 2 and onwards, the creators took his quirks and made him a full-blown GeneralFailure. And yet, he was still able to seriously threaten Kim and, indeed, the world, in ''[[WesternAnimation/KimPossibleMovieSoTheDrama So the Drama]]''.
** Ron, concerning his competence. Ron went from fairly competent PluckyComicRelief at the beginning of the series to BumblingSidekick / ButtMonkey by the end of the end of the third season. In the fourth season, he began to go through CharacterDevelopment that came with his RelationshipUpgrade with Kim that culminated in a moment of CrouchingMoronHiddenBadass in the last episode. True, he had a few instances of his bumbling self throughout the fourth season, though it was most likely done for comedy.
* ''WesternAnimation/TheLandBeforeTime''
** Petrie was initially cowardly and could be a bit of a jerk from time to time. As the series progressed, however, his cowardice has been increased to the point of full blown superstition. In the TV series he refuses to fly over a volcano based on the theory that it would make said volcano angry and cause it to erupt.
** Subverted with Cera. In the early films she disagrees with Littlefoot simply out of pride and wanting to be the leader. As the series goes on her dissents become increasingly rational and thought out.
* In ''WesternAnimation/TheLegendOfKorra'', main character Korra underwent at least two flanderizations. She started out as an assertive and brave little girl, prone to action, although with some insecurities because of her difficulties into mastering airbending. Second season saw her turning into a bossy controlling girlfriend, who treated her former teacher as crap, and a borderline psychopath that menaced with starting a war. However, season 3 and 4 turned the trend around and made her more sympathetic and level-headed when she started actually learning the lessons life threw at her.
** Lin Beifong was flanderizing on Season 2, where from a tough but competent and responsible police chief she became a complete moron who was completely unable to give a chance to her subordinates to do anything. Her personality was restored by the end of the season.
* In the original ''Disney/LiloAndStitch'' movie, after seeing Stitch build a model of San Francisco out of bits and bobs from Lilo's room and then proceeding to wreck it, she tells him she's never going to give him any more caffeine. The later animated series amplifies this side note into "give Stitch coffee, and he goes completely berserk".
** They did this to Pleakly as well. There was a short joke in the original movie about him secretly putting on his wig when he was alone "because it made him feel pretty", but in the series, he lost all pretense of masculinity and was even called "Aunt Pleakly".
** Both Pelekai sisters. Lilo, compared to her TV counterpart, was a bit more mature for her age despite her weirdness, which also got a bit of the boost. Nani, on the other hand, has this problem with her anger. In the movies, this was because of being pressured to find a job to support herself and her sister. The TV series make her come off as a bit of a bitch at times, like in "Bonnie & Clyde", [[DisproportionateRetribution where she grounds Lilo & Stitch for "running around the house and burping"]].
* ''WesternAnimation/TheLooneyTunesShow''
** WesternAnimation/BugsBunny seemed to go through some reverse Flanderization, as he is now usually more down to earth to the point of sometimes being the OnlySaneMan. But ''that'' got somewhat flanderized too, to the point of almost becoming the show's PuritySue.
** Lola has been flanderized (some would say [[TropesAreTools for the better]]) from her debut in ''Film/SpaceJam'' due to complaints of her being a MarySue, to the point now where, depending on the episode, she's either a {{Cloudcuckoolander}} or TheDitz. She's still a StalkerWithACrush in either form.
** Played sadly straight wih WesternAnimation/DaffyDuck, who took levels in [[TookALevelInDumbass stupidity]] and [[TookALevelInJerkass jerkiness]] to the point of having almost ''no'' truly redeeming aspects (except for a ''very'' rare JerkWithAHeartOfGold moment every now and then), also being made the StrawLoser compared to Bugs. And he's getting WORSE.
* [[WesternAnimation/{{Madagascar}} Rico and Mort's]] one scene moments in the first ''Madagascar'' movie have been cranked UpToEleven in [[WesternAnimation/ThePenguinsOfMadagascar the spin-off]]. In one scene in the first movie, the penguins were trapped in a cage, so Skipper commands Rico to break them out. Rico coughs up a hairpin and sets them free. This has been completely flanderized into making Rico [[StomachOfHolding regurgitate anything]] when given the chance. In another scene, the lemurs were hiding in the shrubbery, and at one point, Mort clings King Julien's feet for security. This evolves into a running gag, and an ''obsession''. In fact, there was even an episode where Julien had it up to his crown with Mort's obsession of touching the former's feet that the latter was banished temporarily.
** Also Julien's selfishness, incompetence, ego and stupidity (and his [[WhatTheHellIsThatAccent weird accent]], although this could be chalked up to Danny Jacobs [[TheOtherDarrin replacing]] Sacha Baron Cohen), Maurice's ButtMonkey status, Kowalski's [[TheSmartGuy intelligence]] and Skipper's paranoia. Everyone bar [[OnlySaneMan Private]] was Flanderized.
* In the earlier ''WesternAnimation/MakingFiends'' original web cartoon, [[TheFool Charlotte]] was a [[CheerfulChild very optimistic]] NaiveNewcomer who tried to see the best in everything and everyone, albeit with a scant sense of logic and a few realistic dislikes every little girl would have. Later in the web series and in the TV series, she is a virtually indestructible [[ThePollyanna Pollyanna]] IdiotHoudini, and "Tee hee!" with other exclamations of joy have become her {{Verbal Tic}}s instead of her catchphrases. The only thing that shuts off her smile is when she hears a poem about a cat in danger, [[AssPull for no reason other than to the inconvenience of Vendetta.]] Vendetta, the VillainProtagonist, had less of this than Charlotte, but she went from a narcissistic [[CardCarryingVillain card-carrying]] bully with supernatural abilities to a stereotypical villain who abuses the EvilLaugh (which was originally an occasional [[GigglingVillain giggle]]), and her obsession with [[TrademarkFavoriteFood clams]] goes all the way to the name of the town. However, this was probably all deliberate to make the girls bigger [[{{Foil}} foils]] of each other.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has several examples:
** The episode "Too Many Pinkie Pies" (season 3, episode 3) pretty much parodies this trope, as the clones are basically extremely flanderized versions of Pinkie. The original Pinkie is the LifeOfTheParty and would often get carried away, but made attempts to rein in her craziness out of respect for her friends. The clones are mindless and hyperactive, only capable of wrecking Ponyville and chanting "FUN! FUN! FUN! FUN!"
** Twilight Sparkle was initially a fairly lucid if prudish student who simply had poor social skills. As episodes pass, her geeky, [[TheFinickyOne finicky qualities]] are exaggerated more and more, giving her SuperOCD qualities and a tendency for neurotic snit fits. Her acerbic qualities also faded, making her more naive and hammy.
** Inverted for Applejack, who was originally more a HotBlooded cowgirl, with most of her Aesops concerning her occasionally self righteous or [[HairTriggerTemper short fused]] demeanor (especially concerning her rivalry with Rainbow Dash). After Season One she mellowed out into a more laid back TeamMom, and is the most likely of the six to convey a [[TheEveryman "normal"]] point of view. Though she does get occasional {{Character Check}}s to her original personality.
** Pinkie Pie's hyperactivity and AdultChild tendencies are much more pronounced in season 4 than in previous seasons.
* WesternAnimation/{{Pete}} in Creator/{{Disney}}'s cartoons: from the mere pursuer of a typical cartoon pursuer-pursuee relationship with {{Mickey|Mouse}} to a criminal mastermind. This was parodied in ''VideoGame/KingdomHeartsII'' when he time traveled and met his former self.
* ''WesternAnimation/PhineasAndFerb''
** Phineas Flynn went from being an occasionally [[DeadpanSnarker snarky]] genius [[TheEveryman Everykid]] trying to have some fun during summer vacation to being ''optimism and enthusiasm personified''. It's gotten to the point that if the writers want to pull some OOCIsSeriousBusiness, all they have to do is have him act mildly irritated.
** Also happens InUniverse in "Split Personality", where Candace becomes split into two selves representing her biggest obsessions: busting Phineas and Ferb and Jeremy.
** Buford started off as a {{Jerkass}} bully who beats up everybody, but soon evolved into a JerkWithAHeartOfGold until he was just a slightly edgy kid who beats up Baljeet a few times an episode.
** Dr. Doofenshmirtz, once able to take Perry in a fight or actually pose a credible threat, gets progressively more inept and silly, barely posing any sort of challenge whatsoever. His attachment and obsession with Perry is exaggerated to the point he cannot survive a single second without him. His intelligence and science abilities are also nerfed as his daughter explains he hasn't even actually earned the title of doctor.
* ''WesternAnimation/ThePowerpuffGirls''.
** In the first season The Mayor was more absent-minded than anything else, then they switched to make him more stupid after that and continued increasing his stupidity in subsequent seasons. By the final two he'd become a TheDitz ManChild. Additionally, his love for pickles went from being a one-shot joke in the first season to one of the things his life primarily revolved around in future episodes, and even TheMovie.
** Mojo Jojo is an interesting case. In TheMovie, he was probably one of the biggest threats of the series, however, the first seasons prove otherwise, that he was just a HarmlessVillain. Although seasons 4 and 5 seemed to show that he still remains an effective villain, as in the case of kidnapping and attempted murder in many cases to Professor Utonium.
* Inverted on ''WesternAnimation/RegularShow'', which has actually downplayed some of the cast's defining traits. Benson and Muscle Man have grown increasingly kind to Mordecai and Rigby (and have abandoned their respective {{catch phrase}}s of "You're ''fired''!" and "You know who else ____? MY MOM!"); Skips has gone from a stoic TheAce to showing actual emotion; and Margaret has evolved from the token female to a caring WomenAreWiser type.
** That being said, Rigby has gone through flanderization, even venturing into {{Jerkass}} territory, with the way he treats Mordecai, Skips, Benson, etc., and especially the way he intervenes with Mordecai's attempts to get with Margaret. But let's admit it, he's way nicer in the newer seasons.
* In the original Creator/JohnKricfalusi episodes of ''WesternAnimation/TheRenAndStimpyShow'', Ren was a JerkWithAHeartOfGold who despite his greedy and egotistical behavior and physical abuse towards Stimpy, deeply cared for his best friend. The episodes produced by Games Animation after John K's firing greatly reduced Ren's most sympathetic traits, turning him into a JerkWithAHeartOfJerk with no real affection towards Stimpy. Also, while Ren in the Spumco episodes would be only driven into psychotic rage in the most mentally taxing of situations (i.e. "Space Madness"), Games Ren would yell and scream at the slightest provocation.
** [[ZigZaggingTrope Zig-zagged]] for ''Adult Party Cartoon''. While Ren is still far more sociopathic than in the earlier Spumco episodes (and perhaps even the Games ones), he has at least some palpable softer or repentant moments like before.
* ''WesternAnimation/{{Rugrats}}'' (which is very strange for a {{Long Runner|s}}) cleverly avoided this trope for the most part with the exception of the baby speak, but Chuckie was flanderized, going back as far as season 2. In the first season, he was more of the cautious baby that occasionally got scared of certain things. But by season 2, this is amped up to 11 to the point where he is scared of Wilford Brimley.
** Angelica has actually suffered this twice. In the first season, she was more of a {{Jerkass}} who hardly had any sympathy for other characters but herself, but by seasons 2 and 3, she became more of a JerkWithAHeartOfGold with a Jerkass moment here and there.
** By later seasons, Angelica was flanderized again to the point of her JerkWithAHeartOfGold status overshadowing her {{Jerkass}} status from earlier seasons, meaning that her Jerkass moments were only there occasionally and to a usually more petty and ineffectual degree.
* ''Franchise/ScoobyDoo''
** Fred used to be somewhat intelligent (though not as much as Velma) and serious about the mysteries. However, beginning with ''WesternAnimation/APupNamedScoobyDoo'', Fred was "dumbed down", and thus began to constantly use the "LetsSplitUpGang!" catchphrase, believe in wild crazy theories about aliens and monsters, and blame the neighborhood bully [[MeaningfulName Red Herring]] at the end of each mystery for being the monster (99% of the time, it wasn't Red.) This also carried over to ''WesternAnimation/WhatsNewScoobyDoo'', when in addition to his trademark ascot, his seriousness and intelligence had also disappeared, and was now in ''love'' with the Mystery Machine, and was somewhat not very cool anymore (any attempts to impress the others usually failed miserably). Daphne wasn't immune to this either; she changed from the sexy "danger-prone" eye candy she originally was into a rich valley girl that was paranoid about messing up her hair and clothes, and would often be the one to get the gang out of trouble when Fred would fail to do so.
** In the 1980s series ''The New Scooby-Doo Mysteries'' and the ''WesternAnimation/The13GhostsOfScoobyDoo'', Fred and Velma were gone and Daphne became the leader of the Scooby Gang and was more intelligent and the one solving the mysteries. She retained her original hotness with Velma's brains added in.
** While Daphne TookALevelInBadass in the live-action movies and is usually considered to have been RescuedFromTheScrappyHeap, the same films arguably flanderized Velma from being "the smart one" into being a one-dimensional stereotype of intelligence, swapping actual characterization out for supplying whatever obscure knowledge was necessary to make a given puzzle click.
** Scooby-Doo himself was originally just scared easily but ever since ''What's New, Scooby-Doo?'' he has been looked upon as a full blown coward to the point just uttering the words haunted and place in the same sentence will make him run and hide for cover. The same with Shaggy as well.
** ''WesternAnimation/ScoobyDooMysteryIncorporated'' leaves Scooby and Shaggy largely intact, but has taken a lot of flak for its alterations to everyone else. Fred's predominant trait has gone from choosing to be with the girls when the gang splits up to being obsessed with making traps, a small part of older Scooby plots, to the point that, quite contrary to his older role, he often ''ignores'' Daphne. Daphne herself has largely undergone re-{{Chickification}} thus far not displaying any ActionGirl tendencies and being primarily focused on regaining Fred's attention. Velma, alas, may not be an exaggeration of her past persona but a ''completely changed'' character, having become a ClingyJealousGirl to Shaggy.
* Antoine of ''WesternAnimation/SonicSatAM'' was originally rather pompous and cowardly, but had some amount of lucidity and nobility. By Season Two however he is more or less a full time StrawLoser for Sonic, barely able to spend five seconds without saying or doing something stupid or narcissistic and acting like a full blown DirtyCoward. In retaliation Sonic's originally more playful rivalry towards Antoine evolved into flat out naked contempt (though the lengths of his other traits were usually more a case of DependingOnTheWriter).
** Sonic did however become noticably more cocky and incompetent in the Second Season. More than half the episodes are devoted to Sonic making some sort of error out of recklessness and needing to be bailed out by the rest of the team, compared to Season 1, where he made only a moderated amount of blunders, and could even play the StraightMan to Sally or others' own foolishness.
** Sally in contrast had her positive aspects exaggerated, starting off as a smart but pompous NotSoDifferent Foil for Sonic in season 1 who could occasionally hold the IdiotBall depending on the circumstance. She is practically his HyperCompetentSidekick in season 2 to accommodate his increased recklessness. In addition her more specified intellect (hacking and strategics) became expanded into making her a full blown tech wiz, often rendering Rotor redundant.
* The Warden of ''WesternAnimation/{{Superjail}}'' started off as a goofy yet crafty and sadistic type, and was considered a powerful force in the jail to the point where he took over the ''world'' in a possible future timeline. In season 2, his childish side became more of the focus than his sadism, with him winding up easily getting his jail taken over twice, getting beaten up by his own inmates and made to cower from them, and generally becoming more outgoing yet naive). These changes [[BrokenBase have been met with mixed reaction]], while season 3 continued the emphasis on his man-child nature, showing him to drink grape juice and depicting him as clueless as to how sexual intercourse works.
** Alice started out as being shown to abuse her power to force inmates to do humiliating things for her own pleasure. In season 2, her assertion of her femininity became more of the focal point, along with jokes about her bulge. Her initially one-time "date" from Superbar and his fear of her became a running gag, with her being shown to obsess over him and wanting to keep him hers.
** While the Twins had been hinted to be something other than human, their [[OutOfFocus limited screentime]] and characterization in season 2 ramped up their strangeness while confirming their alien status. Throughout their few appearances in the season, they were shown to consume all sorts of would-be toxic chemicals (including rat poison and bleach), depicted as having ''fangs'', animated in a more stretchy fashion, and referring to blood as "human juice". Their status as troublemakers also seemed to be simplified to "Twins do something random" by the turn of season 3, save for an episode or two.
* While the [[WesternAnimation/TeenageMutantNinjaTurtles1987 1980s animated version]] of the [[Franchise/TeenageMutantNinjaTurtles Ninja Turtles]] were always wisecracking heroes who would [[NoFourthWall occasionally break the fourth wall]], they overdid it a bit in ''WesternAnimation/TurtlesForever'', much to the chagrin of their [[WesternAnimation/TeenageMutantNinjaTurtles2003 2k3 counterparts]]. The movie even goes as far as to {{lampshade|Hanging}} their version of April O'Neil's habit of [[DamselInDistress getting kidnapped a lot]] to point that one of the turtles make the claim that they "save April at least once a day".
** ''Turtles Forever'' flanderized '80s Shredder and Krang in just a couple of scenes. In the first half when the '80s Shredder is seen, he seems to genuinely want to kill the Turtles and isn't afraid to use deadly force (incompent maybe but still deadly in intent), and in frustration to kill them he summons his 2k3 counterpart. But by the second half he is whining over petty things and devolved into a HarmlessVillain.
** Baxter Stockman's amalgamation with a fly in the episode "Enter: The Fly" lowered his intelligence and put holes in his memory, but he was still able to perform fairly complex tasks, and put one of his previous inventions to use. Towards the end of the following season in "Bye Bye, Fly," he was even able to set an elaborate trap for Krang and Shredder. But his intelligence dropped in each of his appearances in Seasons 4-7. In "Son of Return of the Fly, Part II," he was easily distracted from his villainous plans by things like sugar. In "Landlord of the Flies," he [[TooDumbToLive sent a swarm of flies to engulf the Technodrome in Antarctica with obvious results]]. In his final appearance, "Revenge of the Fly," his distractions were so bad that he couldn't carry out the steps of his revenge scheme without getting constant reminders and pointers. This is actually TruthInTelevision when you realize that [[FridgeBrilliance Baxter was part fly, and most insects have bad focus and terrible memories]], so his extreme personification as an AbsentMindedProfessor makes perfect sense when you think about it.
** Slash also got stupider over time. Ironically, the first episode to do this, "Donatello Trashes Slash," was about him becoming a supergenius. It makes Slash's normal state noticeably stupider than in his début episode. His third and final appearance, as a supporting character in "Night of the Rogues," shows him barely even able to speak. {{Justified|Trope}} somewhat, because of the fact that he was a baby before he was mutated. Doesn't really explain his getting stupider, though.
** Vernon Fenwick was introduced as April's foil, a professional rival with a play-it-safe attitude at odds with her bold determination. But he came through for her at the climax of the original miniseries, risking his job (and possibly his life) to help her cover the story of the Turtles fighting the giant android. He was also sometimes [[JerkassHasAPoint right to point out April's recklessness]]. The following seasons painted him as a DirtyCoward who only did anything brave if it meant stealing the spotlight. His cowardice, incompetence, egotism, and effeminacy (which wasn't even present at first) all got stronger and stronger, eliminating whatever redeeming qualities he once had.
** Michaelangelo himself. When the series began, he was an incredibly [[TheDitz ditzy and childish]] (but still likable) surfer boy who loved pizza with weird toppings. As the series continued, he became ridiculously stupid, his love for pizza became ''outright SEXUAL'', his taste in toppings became more and more disgusting and inedible, and his valley boy speak bordered on [[TotallyRadical incomprehensible]].
** Raphael went from a grumpy DeadpanSnarker to a {{Jerkass}} PungeonMaster.
* The [[WesternAnimation/TeenageMutantNinjaTurtles2012 3rd Ninja Turtles]] cartoon has had this become particularly noticeable, especially in the second season as its progressed. Raphael's {{Jerkass}} qualities have been greatly increased compared to any other incarnation, and Michelangelo's role as the jokester of the group led to him [[TookALevelInDumbass losing a severe amount of intelligence]] and repeatedly coming close to getting himself and his brothers killed. Donatello has a series exclusive case: in addition to his usual role as the team brains, he also gained [[InterspeciesRomance a crush on April]]. This latter element however became his sole domineering trait and he pretty much spends most if not all of his time pining for her more than anything else.
** An inversion happens to the turtles' disobedience to Splinter, however.
* Twayne Boneraper from ''WesternAnimation/UglyAmericans'' went from being Mark's intimidating, competent boss to a ditzy ManChild barely tolerated by his fellow demons in just a few episodes. Later his naivety and submission to his huge [[MyBelovedSmother mother]] were upped even more.
* ''WesternAnimation/TeenTitans''
** The [[QuirkyMinibossSquad HIVE kids]] were initially a competent villain team and the collective {{Evil Counterpart}}s of the Titans, sliding into infighting and immaturity only when not "working". Later seasons flanderized them into being all incompetents (except for [[DarkActionGirl Jinx]]) who only won because they got lucky.
** Their boss, Brother Blood, was in his first appearance a cool-headed, charismatic leader who only overacted when playing to an audience; later appearances made him a straight LargeHam.
** Notably, the Titans themselves and BigBad Slade inverted this trope; in the first few appearances they were defined by one or two traits (i.e. Robin was serious, Raven was a {{goth}}, Beast Boy was an immature jokester, Slade was a CardCarryingVillain, etc.), but later appearances added a lot more depth to all of them.
* ''WesternAnimation/TeenageMutantNinjaTurtles2012''
** Oh, Donatello. What makes this incarnation of him especially infamous is his unhealthy obsession of April. At first, fans thought that his crush was adorable and they supported him. However, as of season 2, his crush is less charming and more disturbing. There were people who still support the couple, but others have given up on him. [[spoiler:He seems to have given up on April, but the writers are implying that she feels the same way for him.]]
* [[WesternAnimation/TexAveryMGMCartoons Droopy]] started out as having a milquetoast, fretful personality who could be capable of great strength when roused to anger. Later characterizations give him an almost flat and bored personality whose primary attributes were being TheCatCameBack and OffscreenTeleportation personified. [[InvincibleHero And he never loses.]]
* Many characters on ''WesternAnimation/ThomasTheTankEngine'' have been hit hard with this trope, but special mention goes to Percy and James. Percy was initially intelligent and mischievous, if a bit naive. Since season 7, he has been smacked upside the head with Flanderization, becoming incredibly clueless and naive, and always needs help from someone else. James, similarly, started off the series as a cheerful and hard-working (if somewhat snobbish and conceited). As time went by, he gradually became a lazy, spoilt narcissist.
** Gordon and Henry. In the earlier seasons, Gordon was somewhat pompous and would only occasionally brag about his importance. However, as the series went on, his ego increased to the point where he couldn't go for one minute without bragging about how great he is. Henry used to be somewhat depressed and timid, but could still stand up for himself. Since Season 8, he became an incredibly neurotic and miserable coward.
** Edward started out as an old, sensible, and friendly engine. Around Series 6 the others suddenly lost all respect for him, and his old age led to him being portrayed as just feeble. More recently he's turned into sort of an attention whore who tries in vain to keep the others' respect.
** Toby started out a StraightMan to the other engines, and was one of the most confident and efficient engines. As the show branched from the books, Toby gained a more {{Adorkable}} side, but aside from gaining his own token flawed moments, was still fairly competent. In later episodes, he is an outright ShrinkingViolet, gaining similar feeble tendancies as Edward and frequently conveying self esteem issues or cowardice.
** Thomas himself started out as a snarky trickster in the first two series. In Series 3 he started becoming more friendly, but still thick-skinned. Starting around Series 8, his universally good-natured side took over, and he suddenly needed validation every time another character said something mean to him. By Series 13, he's become a CloudCuckooLander who leaves disaster in his wake as he tries to do something he thinks will benefit someone else.
** The Fat Controller was originally a firm-but-fair authoritarian who was coyly aware of what his engines were up to most of the time. Later he became more of a background figure who only appears to give engines jobs and to tell them when they've done something wrong.
** 'Arry and Bert, the steelworks diesels, had an almost nightmarish first appearance, but by the time they showed up again, they were minor nuisances.
** The narrow gauge engines have changed pretty drastically. Skarloey and Rheneas went from old and wise to a couple of juvenile pranksters. Sir Handel went from snobbish and self-centered to wise and helpful.
** Rusty, who started off as a kind helpful engine who rarely let personal gripes get in the way of work, turned much more careless later on. Duncan started off rude and obstinate, but started to calm down. Then they made him rude again, and worse yet, always forgets everything he's supposed to learn. What were they thinking?!
** A lot of the Flanderization in later episodes is owed to passing the SanityBall. Whoever is the main focus is usually the one getting their shortcomings enthasised and exaggerated while the others will be toned down and act as more rational foils. Thomas for example can range between a thoroughly competent best friend and source of advise to a Spongebob-esque well intentioned {{Cloudcuckoolander}}. James also interchanges between being a brainless narcissist or even more toned down than his original persona.
*** The new writers for Season 17 and onwards though, have begun to restore the original personalities of the characters on the show. Some added facets from the newer series (such as Thomas' [[AttentionDeficitOohShiny attention deficit]] and Henry's [[TookALevelInKindness softer personality]]) still remain, though mercifully don't overtake their entire personality.
* ''WesternAnimation/TotalDrama'' Flanderized several cast members as it transitioned into ''Total Drama Action'' and ''Total Drama World Tour''.
** In ''Total Drama Island'', Courtney was bossy and uptight, but still one of the more moral characters, and only threatened to sue when she was unfairly kicked off the show. In ''Total Drama Action'', she's become a control-freak bitch who threatens to "call her lawyers" at any opportunity.
** DJ starts as a genuinely nice guy and sensitive soul in season one; he was slow to anger, but could be mischievous (helping to prank Harold) or tough (throwing Owen off the cliff in the hunting challenge). By season three, he has become a complete MommasBoy who is reduced to a blubbering wreck because ''the tundra reminds him of his mama's freezer!''
** Cody was originally a CasanovaWannabe who flirted with all the girls when he arrived on the island; he just eventually settled on Gwen as his preferred girlfriend. By season three, he's a [[SingleTargetSexuality Gwen-sexual]] who never seems to consider dating someone else as she continually rebuffs him.
** Justin is a weird example: first he was a FlatCharacter who [[InformedAttractiveness apparently was really hot]], but during the TDI special he suddenly showed a sneaky side, and the first few episodes of TDA hinted that he would be the new villain. However, that [[AbortedArc arc was aborted]], and soon he was just too concerned about every split end or bruise on his precious face to possibly think about any schemes or trickery.
** Duncan. In TDI he was a JerkWithAHeartOfGold, with [[LoveInterests Courtney]] as his MoralityPet. By season two, his bullying of Harold has gone UpToEleven, to the point he kicks him in the testicles and nearly breaks his spine. By season three he suddenly is able to cheat on Courtney without a single twinge of his conscience and acts like a {{Jerkass}} when she finds out and breaks up with him.
** Lindsay started out as your typical DumbBlonde, then in ''All-Stars'' she became an {{exaggerat|edTrope}}ion of the trope who doesn't even understand basic concepts such as ''the difference between pushing and pulling'' and also became one of the show's biggest liabilities to their teams. The Heroic Hamsters were lucky she was the first person to be eliminated.
** Chris's increasing sadism and lack of genuine empathy has grown since the first season, becoming worse and worse with each passing season. By the time the fourth rolled around, the original cast wanted nothing to do with him ''and'' the show in any capacity whatsoever -- only appearing in brief cameos due to their legally binding contracts. It's actually been lampshaded a few times, with Chris blaming it on the time he spent in prison after the fourth season.
* Grimlock and his Dinobots from ''WesternAnimation/TheTransformers'' went from being strong, but unintelligent wild cards in the first two seasons to comic relief in [[WesternAnimation/TransformersTheMovie the movie]] and onward.
** In TheMovie, at least, the Dinobots were still pretty {{Badass}}, though they were suddenly happy to take orders from Optimus Prime and work with the other Autobots. In the third season their badassness evaporated entirely, and went from being DumbMuscle to outright idiots.
** Fortunately their final appearance in "Call of the Primitives" returned them to their brutish and freakishly-powerful standing.
* Optimus Prime has arguably been Flanderized since his original incarnation in ''WesternAnimation/TheTransformers''. Originally depicted as a regular kind of guy (interested in ninjas and able to trash-talk with the best of them) with a slight JohnWayne quality to his voice who leads the resistance on Cybertron, modern portrayals such as ''WesternAnimation/TransformersPrime'' have amplified the reverence and seriousness - and the associated vocal gravitas - to almost godlike qualities, with characters falling silent when he walks into the room, while lighter qualities, such as playing basketball in the original series, have been replaced by the edict that "Primes don't party". [[spoiler:Indeed, a retcon to the ''Prime'' character cast this version as an ''actual'' god, from the Thirteen Original Transformers.]]
** On the other hand, the original Megatron's unrealistic aim to rule the [[strike:galaxy]] universe has been significantly toned down, to the more obtainable desire to return his exiled Decepticons to Cybertron (''WesternAnimation/TransformersAnimated''), or restore the broken planet to its former glory (''WesternAnimation/TransformersPrime'').
* ''WesternAnimation/UltimateSpiderMan'' has one in J. Jonah Jameson. In most versions he's simply a somewhat {{jerk|ass}}y newspaper man with a somewhat justified hatred to Spider-Man. Here all he does is go on for hours on various Bugle Jumbotrons about what a menace Spider-Man is despite knowing full well that he's now working for S.H.I.E.L.D. It's also shown that his negative PR campaign is working better then normal and has turned almost [[NeverAcceptedInHisHometown the whole city against him]].
** This is further shown in the series' sister show ''WesternAnimation/HulkAndTheAgentsOfSmash'' episode "All About Ego", Jameson says that [[InsaneTrollLogic Spider-Man's plan]] to destroy the world with Ego has failed. Keep in mind Spider-Man was not involved in the episode in ''any'' way.
** Phil Coulson too; in the Franchise/MarvelCinematicUniverse, he's established by ''Film/TheAvengers'' as being something of a [[TheKnightsWhoSaySquee fanboy of Captain America]], [[{{Adorkable}} and can be somewhat goofy]]. The series amped this up, making him both a massive ButtMonkey who idolizes Cap, to the point of wearing a Captain America suit under his regular clothes.
** Spider-Man himself; usually Spidey is a DeadpanSnarker with an InnerMonologue with tendencies to not think through his actions, who defaults to being '[[ComicRelief the funny guy]]' when he teams up with others. The show amps up his comedy to the point he's a complete IdiotHero with NoFourthWall who can't stop making dumb jokes.
* ''WesternAnimation/XiaolinShowdown''
** Jack Spicer started off as a legit bad guy and an intelligent one at that. He built his own robots, and on several occasions kicks ass and takes names. By the final two episodes, he's portrayed as so stupid he has to write "This way up" on his underwear. See VillainDecay.
** The other villains were no stranger to this either. Chase Young was introduced as a crafty, cunning character until he devolved into being evil for evil's sake.
** The protagonists had their fair share, too. Omi began with an arrogance typical of a kid his age, but eventually it grew so disproportionate it inflated his head in one episode. Dojo's close relationship with Master Fung started going in the direction of his being a servant of the latter until it grew almost to the point of HoYay.
* Saranoia in ''WesternAnimation/YinYangYo''. Initially, she loathed Yang and men and loved Yin because she was TheUnfavourite compared to her brother Mark, and incorrectly projected that situation onto the siblings, even calling Yang "Mark". Over the course of the series... this backstory started to fade and her already over-the-top idolization of Yin and hatred of Yang was flanderized to the point that she started to come across more like a [[PsychoLesbian creepy pedophiliac lesbian]] StalkerWithACrush, peaking in one episode where she posed as a popular girl to become "Sweat Sisters" with Yin -- everyone ''in the show'' even commented on how creepy that was. Since that episode, though, she's essentially reverted to her original characterization, in an unusual reversal of a Flanderization.
** Master Yo himself. Around the titular rabbits, he would either be just your typical [[GrumpyBear Grumpy Panda]] that taught them well at Woo Foo, or a lazy, selfish Jerkass.
* In ''WesternAnimation/IceAge: A Mammoth Christmas'', the main trio was pretty much flanderized beyond belief; Sid was so stupid that he pretty much said and did things that only a complete asshole would do, no matter how smart they were, but literally did not know any better because he was that stupid, Diego did nothing but make sarcastic remarks, and Manny is pretty much seen as always in the wrong, even when he doesn't really do anything wrong like not believe in Santa Claus.
* Grandpa, and several other characters, get this bad in ''WesternAnimation/TheBoondocks'' animated series. While Huey was always the reasonable one in the show, seasons 1 and 2 saw the Idiot and Smart ball passed around fairly evenly. Grandpa was a hard working, well meaning person who occassionally did stupid things due to lack of foresight and bad luck. However his character was solid enough that he could drop anvils on shady characters like Uncle Ruckus and A Pimp Named Slickback, and words of wisdom to Huey believably. By season 3 it's clear he's an idiot, and by season 4 he's the worst regularly occurring Black person on the show, and only a handful of steps away from being a Black Homer Simpson.
* ''WesternAnimation/JimmyTwoShoes'': The entire main cast was hit hard by this in season 2.
** In Season 1, Jimmy himself was a little airheaded but could be surprisingly clever and was always smarter than Beezy. In the second season, he became a CloudCuckooLander with barely enough intelligence to make Beezy seem marginally dumber. His obliviouness to Heloise's crush on him was turned UpToEleven with Jimmy falling in love with all sorts of women except Heloise (he even fell in love with her robot duplicate) and callously ignored her. this also lead to Jimmy [[TookALevelInJerkAss taking a level in jerkass]]
** The Beezy of Season 1 was very hedonistic and [[PoisonousFriend close to Jimmy to the point of being a little selfish]], but in the end he wasn't evil like his father. In Season 2, his selfish hedonism and Jimmy obsession had created a JerkAss who constantly annoyed Heloise for no reason, harmed and humiliated others for his desires (like forcing children to play a cruel version of Simon says called Beezy Says where losers are beaten up by Lucius' henchmen or freezing his dad over not getting to eat cake), and became very cruel to anything that didn't interest him (like casually breaking up with Saffi just to chase the GirlOfTheWeek or throwing away Heloise's head for being ugly after she went through a series of dangers just to put it back on).
** Heloise did not receive much slapstick in Season 1 compared to the rest of the cast. In what was supposedly recognition of her popularity, she got entire episodes with her as the ButtMonkey like "Better Sweater", "Heloise Schmeloise", and "Heads Will Roll". Her crush on Jimmy was also made more blatant and a more frequent subject.
** Lucius started off as a FauxAffablyEvil CardCarryingVillain who was annoyed by Jimmy for making his people happy. With Jimmy transformed into a screwball in season 2, Lucius ended up being less villainous and more defined by being a [[GrumpyOldMan grumpy old]] OnlySaneMan. While he did have his villainous moments in Season 2, they were less frequent and his kinder moments were more obvious.
* On ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'', Mandy started off as an apathetic AntiHero with DeadpanSnarker tendencies. By the end of the series, she had become a sociopathic EnfanteTerrible [[JerkSue who brought a sense of domination and always seemed to solve the episode's problems by being there]]. Billy went from being a [[DumbIsGood good-natured simpleton]] to a possibly AxCrazy moron becoming more prone to violent outbursts of rage.
