25----
26* ''WesternAnimation/ActionLeagueNow'': The League started out as reasonably effective and respected heroes, though they were still [[IdiotHero morons]]. As the show progressed, they got increasingly dumber and ineffective, to the point that a person is dismayed to see them coming to save him from being flushed down a toilet in "Sink or Swim".
27* Many of the characters in ''WesternAnimation/TheAmazingWorldOfGumball'' began taking rather [[TookALevelInJerkass large levels of jerkass]] in season 2, with Darwin being the most notable offender. On the flip side, Darwin also showed an increase in intelligence, as he was sometimes the first one to call out Gumball whenever they were doing something they weren't supposed to. He isn't as bad as he was in season 3, but he still has he moments.
28** Gumball Watterson had his selfish moments in season 1, [[JerkWithAHeartOfGold but he was still a nice and likable kid]]. However, he became a bigger jerk in season 2, but was actually toned down since Seasons 3 and especially 4, but it varies in Season 5 depending on writer. His intelligence is more moderate as seasons gone by to the point he aced an exam by studying.
29** Nicole always had an [[HairTriggerTemper extremely short temper]] since the series started, but it's gotten to the point where she practically [[HulkingOut turns into]] ComicBook/TheIncredibleHulk or portrays monstrous habits when she gets [[BerserkButton pushed too far]] as of season 2.
30* 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 [[BizarreAlienBiology he'll actually die]] [[ThePowerOfHate without acting consistently cruel]]). Most of his complexities from early episodes such as his loneliness and the fact he is an ''extraterrestrial'' are barely referred to in favor of making him a cross-dressing version of [[WesternAnimation/FamilyGuy Peter Griffin]].
31** 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 (that is until the last episode before the move to TBS, in which Roger did nothing in that episode but be as loathsome and sociopathic as he could be).
32** The flanderization of Roger’s jerkassery and sociopathy became more and more obvious with each passing season but around seasons 7 through 9, the writers somehow decided to make Roger as despicable as possible and decided to have Roger flat out commit heinous crimes without any second thoughts in many episodes. In this case the flanderization on Roger’s jerkiness is so blatant in those seasons that it can’t possibly be seen as anything but intentional.
33*** 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 consistent ButtMonkey from the Smiths' 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.
34*** 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 a German version of Brian Griffin.
35** 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 saw it as a good thing, as he was a fairly generic character. But you'll likely see more people say that said change made him a far more annoying character (the increased number of appearances he got post-Flanderization didn't help either). Lampshaded in one episode post-Flanderization where Steve outright says "I have a hard time believing you're an educator, Brian."
36** Steve's obsession with losing his virginity as well as his bratty nature became his main defining traits in the show's later seasons.
37** 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. However, in exchange for her being less obnoxiously vocal about her liberal ideals, she's also become more of an emotionally unstable hypocrite. Her mood-swings are so massive that she terrified Stan and Francine throughout her teenage years, and whenever a boy breaks up with her (as opposed to her breaking up with him), she goes into such a [[BerserkButton rampage]] that she needs to be tranquilized to avoid destroying the immediate area. The CIA having brainwashed her into a ChildSoldier likely has something to do with her UnstoppableRage.
38** 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 very occasional moments where he was actually ''right'' about something). As time passed however, Stan went from a slightly smarter right-wing take on Peter Griffin to... just Peter Griffin; the necessity for him to learn AnAesop [[AesopAmnesia every episode]] led to him becoming increasingly moronic and childish, and his badass CIA agent qualities became increasingly downplayed in favor of making him a borderline StrawLoser for the rest of the Smiths.
39* 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.
40* 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.
41* 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.
42* ''WesternAnimation/AngryBirdsToons'':
43** The pigs started out as reasonably competent and cunning characters, their downside being that they could be clumsy and suffered from a lot of bad luck. As episodes passed however, they simply got dumber and dumber. They were also flanderized massively in the spin-off series ''Piggy Tales'', in which the pigs were [[TooDumbToLive so painfully, interminably moronic that they were rarely able to complete the simplest tasks without causing unintentional chaos and injury]].
44** Chuck started out as a well-meaning but mischievous speedster, but became an arrogant {{Jerkass}} obsessed with winning by the end of the series.
45* Yakko, Wakko, and Dot Warner of ''WesternAnimation/{{Animaniacs}}'' started out as {{Karmic Trickster}}s who only torment and harm those who have been rude or cruel to them, but several of the later episodes have them bother and harm people unprovoked and be pests just for shits and giggles. One example that stands out is in "Back in Style", where they are loaned out to guest star in parodies of other cartoons and are complete {{jerkass}}es to the cartoons' main characters when their only conceivable crime is being made by studios other than Warner Bros.
46* In the first half of Season 1 of ''WesternAnimation/{{Archer}}'' Cheryl goes from being unstable and mildly neurotic to insane and psychopathic. [[Administrivia/TropesAreTools She's actually funnier and more endearing post-Flanderization]].
47** Another positive example happened with Pam: she goes from complete lonely and pathetic sad sack to the biggest badass in the cast.
48** 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.
49* ''WesternAnimation/{{Arthur}}'':
50** In the later seasons Arthur went from being an average kid with an active imagination, to becoming a super serious character with almost no personality. Barely any episodes of his own show focus on him now because of this, and when they do, he often acts even more out of character. He is now often used as a voice of reason for his friends.
51%% ** Many of D.W.'s personality traits are downplayed in later episodes. ZCE
52** The Brain went from being an incredibly smart kid who still liked things other kids did, to being someone who can't accept almost anything unrealistic.
53** Sue Ellen went from being a tough, but friendly, kind, and the only student capable of intimidating Binky, to being someone unable to stand up for herself when bullied.
54* In ''WesternAnimation/AquaTeenHungerForce'' Master Shake’s laziness, ego, and delusional view of the world were upped as the series went on. The first season had him as the only Aqua Teen to try to get things done in spite of his own laziness and, while he did have a big ego, much of it seemed to stem from him viewing being a detective as a serious job even if he often jumped to conclusions, while later seasons have him as a LazyBum who lounges around the house and refuses to do even the most minor of tasks, believes in things that are utterly nonsensical even by the standards of the series, and can’t go a second without bragging about non-existent achievements.
55* In the first season of ''WesternAnimation/Ballmastrz9009'', Duleena "D.D." Duneeda had a violent temper, but it was only triggered by at least some level of anger. Come season 2, she's freaking out every other sentence with no negative triggers (in the third episode, she goes into rage mode over a hug and ice cream).
56* In the transition from ''WesternAnimation/{{Barnyard}}'' to ''WesternAnimation/BackAtTheBarnyard'', Freddy's attempts to suppress his urges to eat his friend Peck (as Freddy is a ferret and Peck is a rooster) evolved from a minor gag in the film to a recurring trait.
57* In ''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''.
58* ''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 [[Administrivia/TropesAreTools made them much funnier]]. In the revival, there's a case of a De-Flanderized trait; Beavis and Butt-Head, while their stupidity remains, are genuinely seen as smarter and more self-aware of the world.
59** The 2011 revival, however, did have one Flanderization; 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 justified by comparing how relevant HeavyMetal was in 1993 against 2011.
60* ''WesternAnimation/Ben10'' 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 [[EmpathicWeapon 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.
61** 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 a sternly serious, moody, headstrong, hot-headed, stubborn, snarky and occasionally aggressive person who becomes easily irritated.
62** Kevin changed a lot with time. At first he was a delinquent 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 is all forgotten by season 3. Right in 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 of war and never tells Ben and Gwen about it.
63*** He was flanderized again in ''Omniverse''. Kevin loves cars, but in this iteration, it is just ridiculous; he talks about machines and cars almost the time. It is even revealed in a flashback sequence that he even agreed to marry a female Tetramand princess just to get the perfect engine for his car.
64** Ben himself was Flanderized in an ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]'' episode where his ten-year-old self appeared. Somehow, ten-year-old Ben is even less well behaved than how he was back in the original series.
65** 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.
66** Amazingly, ''WesternAnimation/Ben10Omniverse'' put it even further by flanderizing his younger incarnation ''again''. 10 year old Ben back in the original series was an immature brat, sure, but he would get serious when actual danger showed up and show a more mature, softer side on occasion. ''Omniverse'' portrays Ben (who is 11 years old) in the flashback sequences as more obnoxious, bumbling, immature, and even more of a {{Jerkass}} than he was in ''Ultimate Alien''.
67*** ''Omniverse'' 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. However, his flanderization comes back in later episodes, 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.
68** Some returning villains in ''Omniverse'' have been flanderized. For example, the Vreedle Brothers were an ''Of Mice and Men'' -esque duo, with Octogon speaking more intelligently and Rhomboid being a complete idiot. However in ''Omniverse'', both characters became equally dimwitted and incompetent. Another example is their mother, Ma Vreedle. ''Ultimate Alien'' hinted at her level of influence and infamy with her robbing a bank with no resistance and Kevin turning his ship around the moment he found out he was going after Ma Vreedle. ''Omniverse'' dialed up her fear factor to 11, where ''even Vilgax himself'' doesn't want anything to do with her, even though he has the strength, numbers, and loyalty from his army to easily defeat her.
69* ''WesternAnimation/BigMouth'': In Season 1, Andrew masturbated regularly, but he wasn't much more aggressive about it than your typical pubescent teenager; he was just a shy, Jewish nerd reluctantly coping with early puberty. While he did suffer from a porn addiction, he managed to break from it within the same episode. As the seasons progressed, however, Andrew's horniness became his defining trait. He seems convinced that he won't survive without masturbating several times a day, and got off in increasingly irresponsible situations, including a funeral, while showing less and less shame. Even Maury, who Andrew used to consider humiliating for his sexual antics, [[EveryoneHasStandards is appalled at some of Andrew's behavior.]]
70* Grandpa, and several other characters, get this bad in ''WesternAnimation/TheBoondocks''. 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 occasionally 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. (By that time however, creator Aaron [=McGruder=] was no longer attached to the program, so it could be argued that everyone's writing suffered.)
71* While ''WesternAnimation/{{Caillou}}'' isn't as bratty in the later episodes, he is ridiculously/unrealistically happy almost all the time in Seasons 4-5 and the CGI reboot. Caillou even went back to throwing tantrums in ''Caillou's New Adventures''. What's worse is that he's also more loud and obnoxious than before.
72* Cat from ''WesternAnimation/CatDog'' went from being a [[{{Tsundere}} rough-skinned]] [[JerkWithAHeartOfGold but overall friendly brother]] who genuinely cared about Dog whenever he's been humiliated to a greedy JerkWithAHeartOfJerk who often abuses the poor guy just for shits and giggles. Conversely, Dog went from a KindheartedSimpleton who was [[InnocentlyInsensitive oblivious to the torment he caused Cat]] to a PsychopathicManchild who often puts his brother through hell without any second thoughts.
73* Scoutmaster Lumpus from ''WesternAnimation/CampLazlo'' was initially characterized as something akin to Squidward; [[JerkassWoobie a stern and grouchy but amiable fellow who just wanted peace and quiet from Lazlo's antics]]. In later episodes, he became a selfish, dull-witted, and irresponsible {{Jerkass}} PsychopathicManChild who couldn't care less about Camp Kidney's outstandingly poor quality. It got to the point where Joe Murray said [[OnlySaneMan Slinkman]] was the real scoutmaster of the later seasons in all but job title. [[Administrivia/TropesAreTools This made Lumpus a lot funnier though]].
74** As Lumpus took levels in [[TookALevelInJerkass Jerkass]] and [[TookALevelInDumbass Dumbass]], Lazlo TookALevelInKindness. He was initially a [=SpongeBob=]-like character; optimistic, eccentric, and often annoying to everyone but his friends. Later episodes played up his optimism making him an almost hippie-like AllLovingHero with his IdiotHero tendencies being a smaller part of him. Weirdly, this may be because Lazlo became [[DemotedToExtra less of the main character]] over time and more of TheFace of the show as later episodes tended to focus on the rest of the cast with Lazlo either not appearing at all or only having a few lines.
75* ''WesternAnimation/ElChavoAnimado'' did this in regards [[Series/ElChavoDelOcho of the original series]]:
76** El Chavo TookALevelInDumbass. He was already dumb in the original, but here, his stupidity increased to the point of becoming TheDitz of the show.
77** Quico became a much more [[{{Jerkass}} mean]] [[ItsAllAboutMe selfish]] [[BrattyHalfPint and rude boy]] who often shows LackOfEmpathy signs.
78** Ñoño TookALevelInJerkass and became a troublemaker [[ItAmusedMe for fun]].
79** Don Ramón became a LazyBum who doesn't even want to go out to look for work and wants to have everything with the slightest effort.
80** Doña Florinda has become a much more aggressive and mean woman than in the original, to the point where she often has UnstoppableRage.
81** Doña Clotilde's [[AbhorrentAdmirer obsession with Don Ramón]] was upped to rather grating levels, that she could be compared with characters like [[WesternAnimation/LooneyTunes Pepe Le Pew]] or Animation/{{Pucca}}.
82** Jaimito's RunningGag about remembering his hometown Tangamandapio has increased that he's now a {{Cloudcuckoolander}}.
83* 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.
84** Chowder himself too, having transformed from a typical naive little boy [[TookALevelInDumbass to a flat-out dumbass]].
85** Mung's wife Truffles became much more abrasive and mean in the second season to the point where CH Greenblatt himself felt she had virtually no redeeming qualities. This might be because she made less significant appearances in those seasons as Greenblatt felt there was little entertainment to come out of such an unlikeable character.
86* ''WesternAnimation/{{Clarence}}'':
87** The titular character being naive and clueless was always his sole deeming personality, but earlier episodes had him being a rather naive imaginative child with few standards. Overtime, though, his naivety became over exaggerated in later episodes of the second half of first season (depending on the episode) where [[TookALevelInDumbass he became more ostensibly stupid]], becomes over saturated with KarmaHoudini and IdiotHoudini, where he gets into trouble-making, especially with Sumo as sole subject, and will often get away without facing any consequences or some type of punishment to start with. However, a small amount of episodes can be easily taken back on the actions he made.
88** Jeff went from being an OCD, yet a well intented boy with a few set of standards and morals to lay upon, to being a borderline self-centered narcissistic, egotistic jerk that would use Clarence as pawn just to being desperate to attention to all of the other kids, to whom they don't find him cool or that interesting at all. However, the second and third seasons [[CharacterRerailment made him less of a jerk, sticking to his original roots of being moral to subjects]], and had gotten used to Clarence and Sumo, based on their hijinks.
89** Sumo originally started off as well intentioned streetwise kid who had no intention of being a troublemaker ([[DependingOnTheWriter depending on the episode]]). He later becomes a borderline insane freak and a troublemaker who, along with Clarence, will go through all kinds of hell just the shill to start trouble with nearly everyone around, although his over exaggerated insane instincts were always his sole defining trait that he has until at least recently.
90** Belson. From time to time, in the second half of the first one, he came more over a jerkass mostly to Clarence and nearly everyone else, while in Season 2, he was slightly demoted into alone playing with with portable game consoles.
91* ''WesternAnimation/CodenameKidsNextDoor'' Flanderizes several characters:
92** Numbuh Three (Kuki Sanban)'s ditziness. Originally, she was at least as useful as the others (albeit scatterbrained), but soon became a hyperactive ditz who's only useful when Rainbow Monkey dolls are the case.
93** Numbuh Four (Wally Beetles)'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]].
94* ''WesternAnimation/CosmicQuantumRay'' uses this for pretty all much of their characters, but Robbie's school friends especially. Allison is probably the most blatant, as almost everything she says revolves around either her being a vegetarian or her love of animals. This is because the show relies on StatusQuoIsGod, so the characters rarely develop because they have their minds wiped since they can't learn about Robbie's job as hero for reasons, but you'd think a show about teaching scientific concepts would be a little better with this.
95* ''WesternAnimation/CourageTheCowardlyDog'':
96** Katz 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.
97** Speaking of Eustace, he might as well be the epitome of this trope in the whole show. While Eustace has always started off as a greedy, selfish jerk, he was mostly just annoyed and indifferent in the first season like the typical old man. Then in the later season, he became cruel and abusive, primarily towards Courage, and showed him no gratitude after the dog went through all that trouble to save his life many times.
98*** It isn't until "Ball of Revenge" where he goes from downright cruel to pure evil when he finally hires a group of villains to ''murder'' Courage, going as far using ''his own wife'' as bait to do so. [[WhatDoesSheSeeInHim To this day, many still wonder why Muriel never contemplated divorce after this]].
99** Courage was originally a TalkingAnimal who would openly speak English, but would babble incoherently and mime when afraid. When the executives [[ExecutiveMeddling decided that Courage's screams and babbles were funnier than his one liners]], the crew reduced Courage's dialogue little by little to the point where he rarely spoke coherent English at all.
100* Elise in ''WesternAnimation/DanVs'' has definitely suffered this as the show elapsed. During the first season, she was annoyed of Dan's petty revenge schemes yet still reluctantly tagged along with him and Chris on the quest. Also, she seemed to somewhat enjoy them in some circumstances and [[TeethClenchedTeamwork would fight along with Dan due to sharing his experiences with whomever he's declared vengeance against]]. By the second season, she became downright hostile and hateful towards Dan, only interacting with him because neither she nor Dan want to abandon Chris. To add on to this, [[SpotlightStealingSquad Elise got more episodes focusing primarily on her]], and most of Dan's schemes are solved through DeusExMachina thanks to Elise, [[SeasonalRot which is why the second season is considered the weakest of the series as a whole]].
101* 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.
102** 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.
103** This was ''invoked'' in the episode "Psycho Therapy", where everyone is asked to imitate each other.
104** 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?").
105** 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).
106* The entire Franchise/DCAnimatedUniverse could count.
107** ''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 who has no conception of ''happiness''. It works mostly (unless he goes the full Jerkass route) but it's 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.
108** The animated portrayals of the villains remained more or less stable throughout the series' run, with two notable exceptions.
109*** 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 it's 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.
110*** 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 shrank, so in his last episode he looks barely taller than an Ewok.
111** 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).
112* Mandark of ''WesternAnimation/DextersLaboratory'' in the [[UnCanceled post-finale seasons]] is ''defined'' by his [[LargeHam hamminess]] and crush on Dee-Dee. [[VillainDecay He also becomes much more ineffectual]].
113* Bob from ''WesternAnimation/{{Dinofroz}}'' was physically the FatBestFriend, but he hardly talked about food in Season 1. In Season 2, half of his dialogue consists of him talking about food, eating, or whining whenever he gets hungry.
114* In the Nickelodeon version of ''WesternAnimation/{{Doug}}'', Doug was in love with Patti but always tried not to let that get in the way of their friendship. However, in Disney's Doug, his obsession with her goes so through the roof that he tries to ''stalk'' her in episodes. It also seems like Doug can never get Patti off his mind ,with the majority of the episodes of this series involves him trying to impress Patti in some way; in one episode, one of his fantasies is owing a planet full of Patti look-a-likes. Even Doug's best friend Skeeter [[WhatTheHellHero calls him out over this obsession over Patti]].
115* The ''entire cast'' of ''WesternAnimation/DrawnTogether'', especially Princess Clara. One could argue that this was [[InvokedTrope on purpose]].
116** 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.
117** Meanwhile, Princess Clara completely took over Toot's previous role, going from 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]].
118** Spanky evolves from being a malicious, greedy sadist to a mischievous party animal whose worst antics are defecating on pizza.
119** Captain Hero went from a respected SuperHero with closeted gay tendencies and a frat boy personality to a completely disrespected loser who considers [[ILoveTheDead having sex with dead bodies]] better than coming out of the closet.
120** Foxxy went from being a mystery solving SassyBlackGirl who would occasionally display humorous racial stereotypes to the TokenMinority who represented every black stereotype in the book.
121* 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.
122** 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.
123** In addition, their RevengeMyopia for [[TrappedInVillainy the Urpneys]] (which was originally more just self defensive apathy in the pilot) got exaggerated to relentless UnscrupulousHero levels, with them frequently preaching how evil Blob's men were and taking much more sadistic pleasure tormenting them [[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 panic and opt out the moment [[TheDragAlong Frizz]] and Nug [[ThenLetMeBeEvil become even slightly as malicious as they always claim them to be]], [[ATasteOfDefeat thus costing them a victory]]. After that, the writers seemed to get the point and similarly reverted them back to more pragmatic characters.
124** 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]].
125** 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.
126** 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.
127* WesternAnimation/{{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]].
128* ''WesternAnimation/DuckTales1987'' 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.
129* ''WesternAnimation/EdEddNEddy'':
130** 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 LovableRogue personality and became more violent, manic, and surly. Again, that just covers the main characters. The writers seemed to have picked up on this and in Season Five, the Eds are tweaked to be slightly closer to their original personalities while still keeping the wacky energy of the later seasons.
131** 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:
132*** '''Ed''': Obsession with gravy.
133*** '''Edd''': [[SesquipedalianLoquaciousness Vast vocabulary.]]
134*** '''Eddy''': [[NoIndoorVoice SHOUTING REALLY LOUD!!!]]
135*** '''Kevin''': Using the word "dorks".
136*** '''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.
137*** '''Jonny''': Taking Plank's advice.
138** 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.
139-->'''Edd''' (pretending to be Ed): Gravy!
140-->'''Ed''': Aw come on, Double D! I don't say "gravy" ''all'' the time!
141-->'''Edd''': Buttered toast, then!
142** 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.
143** 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 whom all the kids now disliked and he almost could not act or even function without Plank's input and presence. This is even {{lampshade|Hanging}}d 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]].
144** [[GirlNextDoor 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 cheerleader type who was still pretty and liked by the boys but would also spout one-liners or make "deep" observations that [[TheDitz seemed to defy all logic]].
145** Though we don't see him until the Movie, this arguably applies to [[spoiler: Eddy's brother]], who was initially presented as merely kind of a con-artist and something of a bad influence, but as seasons went on and Eddy's own {{Jerkass}} behaviour increased, the implications of what [[spoiler: Eddy's brother]] was actually like got worse and worse. This is a JustifiedTrope - the writers needed Eddy to have a suitable FreudianExcuse for all the crap he pulls over the series that will [[spoiler: make the cul-de-sac kids forgive him]], so [[spoiler: his brother]] ''had'' to be as nasty as he was in order to justify why Eddy behaved how he did. It also retroactively explained Eddy's increasing jerkassery in later seasons as him doubling down on attempts to emulate his "cool" big bro.
146* ''WesternAnimation/FiremanSam'':
147** A lot of the civilians (especially Norman and the other kids) became exceptionally dumber and more careless in the CGI seasons to necessitate the need for bigger emergencies happening.
148** Zigzagged for characters such as Elvis and Steele, who got their defining traits exaggerated, but also demonstrated more HiddenDepths to balance it. Elvis became more outwardly dopey and clumsy, but got more moments of individual competence on-duty, while Steele became a stricter UpperClassTwit, but also had more playful CoolOldGuy moments.
149* ''WesternAnimation/FostersHomeForImaginaryFriends'':
150** In the PilotMovie, ''WesternAnimation/HouseOfBloos'', Bloo was only slightly mischievous and showed at multiple points he had a very good heart underneath his occasionally brash and boisterous exterior. It took just ''one'' episode afterwards - "[[Recap/FostersHomeForImaginaryFriendsS1E5StoreWars Store Wars]]" - for him to devolve into a violent, insufferable brat who actively attempts to make everyone's lives a living hell by running around a mall attacking people for not giving him things for free to the point where the police are forced to take action[[note]]This was the seventh episode in production order, and earlier episodes in the production order did show a more noticeable transition[[/note]]. By Season 2's "[[Recap/FosterHomeForImaginaryFriendsS2E5CookieDough Cookie Dough]]" wherein he all but enslaves his friends to make himself obscenely rich, his selfishness and greed became so ridiculously extreme that it came across as parody. And he only got progressively more anarchic, selfish, cruel, obnoxious and violent as the series progressed while showing far fewer genuinely nice moments, reaching {{Jerkass}} levels in later seasons to the point where he virtually became a VillainProtagonist.
151** Wilt went from an overly polite and [[ApologizesALot apologetic]] but perfectly sane and approachable nice guy to an ExtremeDoormat and a [[TheWoobie total neurotic who's about five seconds away from a nervous breakdown]]. Eventually the special ''WesternAnimation/GoodWiltHunting'' gave him a FreudianExcuse for his behavior.
152** Eduardo went from a mere scaredy cat [[CowardlyLion who can still stand up for himself at times]] to an extreme {{Cloudcuckoolander}} who acts like a toddler and obsesses over potatoes[[note]]which began as a one-off joke from Season 1's "Bloooo"[[/note]]
153** Herriman went from the usual "uptight British butler" to a tyrannical sadist. And the less we get into his [[GRatedDrug carrot addiction]], the better.
154** Cheese went from "four-year-old with special needs" to "barely sentient baby" by his ''second'' appearance.
155* In ''WesternAnimation/{{Gargoyles}}'', [[AmplifierArtifact the Eye of Odin]] causes this InUniverse. It amplifies the wearer’s nature, making them more powerful, but also makes their defining personality traits go to extremes and consume everything else about them. Goliath, a kindhearted gargoyle who desires to protect the weak, becomes a possessive maniac who fakes danger and keeps the people he has decided to protect trapped inside a cave to protect them from the outside world, and the Archmage, a petty, selfish, egomaniacal sorcerer, becomes a CardCarryingVillain who toys with his victims out of spite for inconveniencing him centuries ago when he could easily have destroyed them and wants to TakeOverTheWorld.
156* 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, Hawk states that Shipwreck has no ambition or ability).
157* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'':
158** Mandy started off as an apathetic AntiHero with DeadpanSnarker tendencies; she was always mean and bossy, but not truly evil, as well as being surprisingly clever for her age. By the end of the series, she had become a sadistic and sociopathic EnfanteTerrible plotting world domination and an InvincibleVillain who could instantly solve any conflict in an episode just by showing up; her apathy also became outright emotionlessness, to the point where her smiling happily ''was considered a RealityBreakingParadox'' by the show's universe.
159** Billy went from being a cheerful and energetic KindheartedSimpleton to becoming a completely AxCrazy and emotionally unstable maniac with his niceness becoming an InformedAttribute and his idiocy being taken up a notch.
160** Grim's ButtMonkey qualities were considerably amplified as the show progressed, making him more pathetic with every season (especially after the transition from ''Grim & Evil'' to ''Grim Adventures''). Initially presented as [[TheComicallySerious a dark and dour figure]] comedically placed in a humiliating position by Billy and Mandy, he was quickly flanderized into a CosmicPlaything -- an ineffectual manchild who could barely handle anything the show threw at him, was deemed a loser even by his fellow supernatural beings, and actually more sympathetic than his child masters. However, he did still occasionally get his LetsGetDangerous moments.
161** Irwin's crush on Mandy became a more dominant trait in later episodes to [[StalkerWithACrush the point where it often reached stalker]] levels. In fact, his lust for Mandy evolved from a mere schoolboy crush to being outright ''sexual'' in its presentation.
162** Billy's parents too. his mother Gladys changed from a ProperlyParanoid but loving mother with the occasional nervous tendencies to a AxCrazy StepfordSmiler permanently on the verge of a mental breakdown while his father Harold went from merely being oblivious and/or apathetic to the fact TheGrimReaper was living in his house and hanging out with his son to [[TookALevelInDumbass a complete idiot]] who's just an older, fatter Billy.
163* ''WesternAnimation/{{Grojband}}'': Trina was very quickly flanderized by the series from a standard bossy, dramatic, and overbearing BrattyTeenageDaughter and AlphaBitch to a [[HateSink hateful]] and [[TeensAreMonsters monstrous]] psychopath who would go as far as to attempt to kill her brother and let the world be destroyed just to make Nick Mallory love her and see Grojband's dreams get destroyed.
164** Curiously inverted with Grojband themselves, who began as rather simple {{Unsympathetic Comedy Protagonist}}s (Corey was an IdiotHero, Laney was largely defined by her crush on Corey and being OneOfTheBoys, Kin was simply TheSmartGuy, Kon was a FatIdiot), but were quickly transformed into more complex and likeable characters around the same time Trina was being flanderized (Corey became a BookDumb BunnyEarsLawyer, Laney became a TomboyWithAGirlyStreak and began to control her feelings for Corey, Kin grew into more of a DitzyGenius MadScientist, and Kon became a GeniusDitz with hints of ObfuscatingStupidity).
165* ''WesternAnimation/HeyArnold'':
166** [[Characters/HeyArnoldArnoldShortman Arnold Shortman]] 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 of advice for all children and ''even some adults'', practically raising him into [[MessiahCreep 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.
167** [[Characters/HeyArnoldHelgaGPataki Helga G. Pataki]] went from being a LovingBully who harasses Arnold to hide her feelings for him to an outright StalkerWithACrush in later seasons.
168* In ''WesternAnimation/IceAge: A Mammoth Christmas'', the main trio is heavily Flanderized. Sid says and does things that only a complete asshole would do, no matter how smart they are, but doesn't know any better because he's just that stupid. Diego does nothing but make sarcastic remarks, and Manny is always portrayed as being in the wrong, [[InformedWrongness even when he expresses fairly normal beliefs like not believing in Santa Claus]].
169* 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 up to eleven where spin-offs like ''WesternAnimation/GadgetAndTheGadgetinis'' were concerned.
170** The dynamic of the show got Flanderized after the first handful of episodes, within which Gadget was somewhat semi-competent, with Penny and Brain only filling in when Gadget's bumbling got too extreme, but in other situations were {{Tagalong Kid}}s who needed ''his'' help (in the pilot in fact, ''Brain'' was ''Gadget's'' BumblingSidekick). Shortly in, the former premise took over, with Penny and Brian regularly solving the entire case with Gadget barely contributing at all [[TheFool besides by accidental buffoonery]]. There were sporadic {{Character Check}}s where Gadget was briefly competent again in the first season, though these even these dwindled in the second season and most revival cartoons.
171* ''WesternAnimation/InvaderZim'':
172** 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 [[CatchPhrase "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. ''Enter the Florpus'' made her less awfully violent and more of a DeadpanSnarker who [[CharacterRerailment did show genuine concern for her family]].
173** 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 (and everyone else's) awareness/obsession/neurosis about the size of his head. This is all somewhat justified, as Dib was initially not considered funny enough by the higher-ups, resulting in [[https://zim.fandom.com/wiki/God_Save_the_Dib drastic changes]] to his character and design to make him more wacky and cartoony.
174* ''WesternAnimation/JimmyTwoShoes'': The entire main cast was hit by this in [[SeasonalRot Season 2]].
175** Jimmy's IdiotHero and CloudCuckoolander qualities were heavily flanderized during the second season, turning him from a naive and childish yet surprisingly clever and sensible [[ThePollyanna Pollyanna]] to an extremely erratic and hyperactive [[TheDitz Ditz]] who was completely incapable of saying or doing anything that could even be remotely considered sane.
176** Beezy had a tendency to hold the JerkassBall in the first season, but he was generally more of a laidback JerkWithAHeartOfGold who would never be anywhere near as evil as his father, Lucius. In Season 2, he transformed outright into a completely obnoxious {{Jerkass}} who would do things like casually break up with his girlfriend just to chase the GirlOfTheWeek or make starving children play "Simon Says" for cake and have the losers beat up by Lucius' thugs for his amusement.
177** Heloise's crush on Jimmy became an increasingly emphasized part of her character as the series went on, reaching ridiculously blatant levels in Season 2. Almost all of her appearances in that season revolved around her trying to woo Jimmy or bring up her crush on Jimmy in some way. That said, the Jimmy/Heloise shippers didn't mind this one bit [[ShipTease for obvious reasons]]. However, Season 2 also made her moments as a victim of slapstick much more frequent than before, reaching ButtMonkey levels.
178** Much like what happened to Plankton in ''Spongebob'', Lucius Heinous VII's IneffectualSympatheticVillain status was exaggerated in the second season, reaching to the point where he could not be considered evil or even a mere {{jerkass}} in many episodes and is instead written as more of a fun-hating pessimist, with his love of causing misery and [[TheCaligula Caligula]] tendencies getting significantly downplayed and his ButtMonkey qualities also being consequently taken up to eleven.
179** Even the setting was flanderized! Miseryville transformed from what was meant to be [[AHellOfATime a wacky, kid-friendly version of Hell]] populated by weird and cartoony demons and monsters where any random weirdness was just meant to be one-off gags, to a nonsensical {{Cloudcuckooland}} where {{Funny Animal}}s and {{Animate Inanimate Object}}s were a normal part of the setting alongside TheLegionsOfHell. The CrapsackWorld aspect of the setting also became more of an InformedAttribute due to Lucius' aforementioned flanderization.
180* The title character of ''WesternAnimation/JohnnyBravo'' got hit with this hard. While Johnny was hardly MENSA material in the first season, he still had some common sense-his main character flaws were [[SmallNameBigEgo overconfidence]] and [[CasanovaWannabe cluelessness on how to deal with women]]. His stupidity and immaturity were greatly exaggerated in seasons two and three to the point where he was even named as the village idiot by the townspeople 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.
181%%* WesternAnimation/JohnnyTest
182* Allison "Allie" Underhill's {{Tsundere}} traits in ''WesternAnimation/{{Kaijudo}}''. Initially, Allie was simply a 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 arguments with him, endangering their friendship.
183* ''WesternAnimation/KimPossible'':
184** [[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]]''.
185** Ron, concerning his competence. Ron went from fairly competent PluckyComicRelief at the beginning of the series to BumblingSidekick / ButtMonkey by 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.
186* ''WesternAnimation/KungFuPandaLegendsOfAwesomeness'' does this to Po and company. Po's lazy and obnoxious tendencies are blown way out of proportion in several episodes, and any flak he receives from Shifu and the Furious Five is unjustified at best.
187* ''WesternAnimation/TheLandBeforeTime'':
188** 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.
189** 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.
190* ''WesternAnimation/TheLegendOfKorra'':
191** The main character Korra underwent this in Book 2. She started out as an assertive and brave girl, prone to action, although not without her insecure moments. The second season played up her assertiveness to the point of being headstrong, leading her to make rash decisions fairly frequently. She gets better by the end of the season, when her character development starts to get into full swing.
192** Lin Beifong also got this a bit in Book 2, where her no-nonsense, stubborn traits were exaggerated to the point of not being willing to hear Mako out at all, even as he brings forth perfectly-reasonable ideas and evidence. She also gets better by the end of the season.
193** [[PluckyComicRelief Bolin]] is also subject to this in the same season, shifting from a [[NiceGuy well-meaning]] [[ManChild but naive and somewhat immature]] character to [[TookALevelInDumbass a full-blown]] IdiotHero. As with the other examples, this is thankfully rectified by the end of the season.
194* In the original ''WesternAnimation/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. ''WesternAnimation/LiloAndStitchTheSeries'' amplifies this side note into "give Stitch coffee, and he goes completely berserk".
195** They did this to Pleakley 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 Pleakley".
196** 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 Series'' made 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"]].
197* ''WesternAnimation/LooneyTunes'', being a LongRunner, couldn't avoid this trope.
198** When WesternAnimation/BugsBunny debuted, he was a crazy trickster with something of a {{Jerkass}} streak. In order for him to become more sympathetic, the crew (especially Creator/ChuckJones) established rules and created villains designed to make him more sympathetic. By the mid-1950s or so, though, Bugs had become quite reserved and infallible, to the point that it became a problem with the staff (particularly Creator/RobertMcKimson, who complained that Bugs had become a FlatCharacter because of it). The early 1960s ''did'' make a few attempts to make him more hyperactive again.
199** When WesternAnimation/DaffyDuck debuted, he was a deranged heckler who wasn't in his right mind. In 1940, Creator/FrizFreleng's short ''Film/YouOughtToBeInPictures'' introduced a greedy AttentionWhore side to the character. Then, in the 1950s, he gradually transformed into to a greedy {{Jerkass}}. However, the {{Jerkass}} aspect of his character was amplified to ridiculous levels in his pairings with Speedy. To the point where, for example, one cartoon had him whipping impoverished mice simply for "starving on his property." While another had him holding up a radio DJ at gunpoint just so Speedy and his friends couldn't listen to music at his electronics store. Fortunately, in the later half of the Daffy-Speedy era, his {{Jerkass}} flanderization was toned down and he became more of a StrawLoser, even falling into JerkassWoobie territory in some cartoons.
200** [[WesternAnimation/SylvesterTheCatAndTweetyBird Tweety Bird]] initially started out as a malicious trickster who actively fought off aggressors in the same vein as Bugs Bunny. After Creator/BobClampett left the studio and Friz Freleng took over the character, he slowly underwent BadassDecay and by the mid-1950s, Tweety was usually protected by some outside force (either a bulldog or Granny) that would prevent Sylvester from getting ahold of the bird.
201** In Chuck Jones' cartoons starring WesternAnimation/WileECoyoteAndTheRoadrunner, the Roadrunner never actually fought back against the coyote, instead simply running along the road and allowing Wile E.'s schemes to foil themselves. In the mid-1960s when Rudy Larriva took over the Roadrunner cartoons, the Roadrunner began to actively fight back against Wile E. Coyote.
202** This was actually ''intentionally'' done for the early character of Piggy Hamhock, who appeared in ''At Your Service Madame'' and ''WesternAnimation/{{Pigs Is Pigs|1937}}''. In the former short, he was portrayed as gluttonous but it wasn't his only character trait as most of his screentime revolved around him exposing a swindler charming his mother. Creator/FrizFreleng got the idea to make the Hamhock family a parody of the Seven Deadly Sins with each piglet representing a sin, with Piggy representing gluttony. Thus, in ''Pigs is Pigs'' his gluttony becomes his defining character trait and his previous noble qualities are removed. The idea for a Hamhock family series was ultimately canned.
203** In post-1970s ''Looney Tunes'' productions, the characters can get this a lot. For example, Daffy tends to be reduced to little more than a {{Jerkass}} StrawLoser who exists to be humiliated and make Bugs look better by comparison. He's also often depicted as genuinely stupid as opposed to being easily manipulated due to his very poor impulse control. Fortunately, [[CharacterRerailment he would return]] to his original {{Cloudcuckoolander}} self starting with ''WesternAnimation/WabbitALooneyTunesProduction''.
204** ''WesternAnimation/TheLooneyTunesShow'':
205*** 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.
206*** WesternAnimation/DaffyDuck 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.
207*** [[Film/SpaceJam Lola Bunny]] is a particularly vexing example, being transformed from a [[TheLadette tough-as-nails]] ActionGirl to a [[{{Cloudcuckoolander}} hyperactive ditz]] who is a StalkerWithACrush to Bugs. However, for some people, [[Administrivia/TropesAreTools this is an improvement]].
208* ''WesternAnimation/{{Madagascar}}'': Rico and Mort's one scene moments in the first ''Madagascar'' movie have been cranked up 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.
209** 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. [[Administrivia/TropesAreTools Although this isn't particularly a bad thing]].
210* 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 {{giggl|ingVillain}}e), 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}}s of each other.
211* ''WesternAnimation/MenInBlackTheSeries'' is spun-off from the film, ''Film/MenInBlack.'' Because of this, several traits chacrters exibited in that movie become exaggerated. Agent J was a rookie in the film, but by the end of it, had grown as an agent. In the series he remained inexperience and needs things explained to him even towards the end of the series. In the film, Agent K was a little on the stoic side, but had a dry wit, while in the series he is all but emotionless. The most egregious example however are the four worm guys. They had one scene in the film, but because they happened to be drinking coffee in that one scene, the animated series exagerated their love of the stuff to the point where it was all they could ever talk about.
212* ''WesternAnimation/MickeyMouse2013'': As the series went on, Mickey's voice became louder and louder. Compare his voice in episodes like "No Service" to ones like "Safari, So Good".
213* ''WesternAnimation/MiraculousLadybug'':
214** The first season showed Marinette as a SmittenTeenageGirl over Adrien, who makes the rare questionable decision over her crush, like many fourteen-year-old girls do. Later seasons, however, have turned Marinette’s crush into an unhealthy obsession. So far, she has broken into his house at least once, tried to sabotage his dates with other girls, stalked him a few times, and even sniffed the things in his room and fangirled over the scent that she memorized.
215** In seasons 1-3, resident AlphaBitch Chloé was shown to have some PetTheDog moments towards others and the ability to eventually redeem herself. Starting in season 4, however, her cruelty has been ramped up to the point that most of the cast considers her BeyondRedemption.
216* Even ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has several examples:
217** In his first few appearances, Big Macintosh spoke normally but also said "eeyup" a couple times, sort of as a CatchPhrase. As [[CharacterizationMarchesOn time went on]], Big Mac morphed into TheQuietOne, only saying "eeyup" or "nope," and virtually nothing else. The few times he does articulately talk past the third season or so are [[OOCIsSeriousBusiness treated as a big deal]].
218** "Too Many Pinkies" parodies this, as a bunch of clones of Pinkie Pie are extremely flanderized versions of Pinkie. The original Pinkie is the LifeOfTheParty and would often [[GenkiGirl get carried away]], but made attempts to rein in her craziness out of respect for her friends, or if she has crossed some sort of line. The clones are mindless and hyperactive, only capable of wrecking Ponyville and chanting "FUN! FUN! FUN!". Pinkie was also originally written as a bit of a {{Cloudcuckoolander}}, often being airheaded and non-serious, but as the series progressed, these traits became more and more exaggerated, to the point where episodes often had her screeching at the top of her lungs and being completely wild and outrageous for no reason other than comic relief. Furthermore, episodes would occasionally bring the story to a complete halt, just to let Pinkie make a joke. This was most prominent in episodes that did not directly involve her in the story, such as "Filli Vanilli".
219** Fluttershy was originally [[ExtremeDoormat quiet and timid]], but was [[CrouchingMoronHiddenBadass capable of showing moments of bravery and assertiveness]] when the situation called for it, like when she made a dragon break down crying in "Dragonshy". Later on, [[NotSoAboveItAll she became increasingly blunt]] and even outright CruelToBeKind when it came to helping her friends or standing up for herself, like when her BrutalHonesty made Rainbow Dash's depression over Tank's hibernation worse in "Tanks for the Memories".
220** Twilight Sparkle was initially a fairly lucid if prudish student [[LonersAreFreaks who simply had poor social skills]]. As episodes passed, her geeky, [[TheFinickyOne finicky qualities]] are exaggerated more and more, giving her ObsessivelyOrganized qualities and a tendency for neurotic snit fits. Due to her acerbic qualities having faded, this makes her more naive and hammy. This eventually became so bad that the last season made it a specific point of an episode to de-flanderize her and bring her back down to her season 1 personality in order to rationalize why she was allowed to become the country's next monarch.
221** 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. Although she did mellow out into a more laid back TeamMom and has been the most likely to convey a [[TheEveryman "normal"]] point of view, she still does get occasional {{Character Check}}s to her original personality.
222* ''WesternAnimation/PhineasAndFerb'':
223** 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.
224** Also happens InUniverse in "Split Personality", where Candace becomes split into two selves representing her biggest obsessions: busting Phineas and Ferb and Jeremy.
225** 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.
226** Isabella's crush on Phineas became a bigger and bigger part of her character as the series progressed, with references to it growing more frequent and her desire to win Phineas' heart growing increasingly important to plots centered around her.
227* ''WesternAnimation/ThePowerpuffGirls'':
228** In the first season, the Mayor was a slightly absent-minded NiceGuy, then they switched to make him more stupid after that and continued increasing his stupidity in subsequent seasons. By the final two seasons, he'd become an [[TheDitz idiotic]] 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.
229** 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.
230** Many fans of the original series feel this way about [[WesternAnimation/ThePowerpuffGirls2016 the reboot]]. Buttercup, who was once sweet and tough, is now willing to destroy a whole school just to prove to her sisters that she doesn't shoot "air balls". Bubbles is no longer sweet and gullible, but rather a little girl who loves unicorns with a crazy side that only appeared in one or two episodes from the original series; Blossom is barely the leader, instead always arguing with Buttercup. Blossom was originally a smart, intellectual girl, however she now has heavy NeatFreak traits on top of being more into grades than before. In comparison to the original characters, a lot of fans feel cheated by the new reboot. Along with that, when they need to fight someone, Buttercup usually does all of the fighting, showing very little teamwork. Ironically, the makers of the reboot said their intention was to flesh out their personalities.
231** Even in the original series, the Girls' Flanderization was apparent. In season 1, they were occasionally impulsive, but well-meaning, and somewhat morally strong girls. Season 2 ended up starting this, as hinted by how Buttercup's centric were now leaning to rather negative territories. Blossom, despite always fighting crime for almost a season and a half, ends up committing a theft crime ''once'', and goes off the far end to try to avoid getting busted, even trying to frame Mojo Jojo for her crime. She has to be forced to confess it, but even then, she was still sympathetic, and got punished for it. In the middle of Season 3, the Girls not only commit more crimes, but turn into selfish, vindictive, abusive, and hypocritical Karma Houdinis, particularly in "Gettin' Twiggy With It", "Candy Is Dandy", "Ploys R'Us", "Powerprof.", "Equal Fights", and "Moral Decay". In Season 4, aside from "Film Flam" and "Members Only", thoae flaws seem to cool down. However, the damage from Season 3 had already been dealt. In "Knock It Off", they take the Idiot Ball massively, and inconsiderately give him Chemical X, somehting they would NOT have done in Season 1. It's really hard to sympathize with them at this point, since they should've already learned this lesson before.
232* In ''WesternAnimation/TheRealGhostbusters'', the four Ghostbusters are based on the characters from the [[Film/Ghostbusters1984 film]], plus their exaggerated traits. Egon is even more scientifically minded, characterized with more "typical nerd" behavior.
233** Within the show itself, the character of Peter Venkman suffered severe Flanderization in the later seasons. Originally starting off as a [[DeadpanSnarker laid back and sarcastic]] character, he later developed into the team doofus. Leaning much deeper into the comedic aspect of his character and having moments where he would accidentally endanger his team, his rivalry with Slimer was also significantly downplayed.
234* Surprisingly 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 "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.
235** 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.
236** Rigby's dad, in the short time he's been on screen, took a colossal level in [[TookALevelInJerkass Jerkass]]. He went from being a kind and caring dad who's proud of his underachieving son in "The Thanksgiving Special", to being a deadbeat dad who often wanders around in his underpants and cares very little for Rigby, valuing his own car more than Rigby.
237* 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.
238** [[ZigZaggingTrope Zig-zagged]] for ''[[WesternAnimation/RenAndStimpyAdultPartyCartoon 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.
239* ''WesternAnimation/RickAndMorty'':
240** Beth started out in season 1 as the OnlySaneMan who was doing her best to restrain the dysfunction in her family, with some NotSoAboveItAll moments. In season 2, her egotism and selfishness were exaggerated to the point that she was more screwed-up than anyone else in the family apart from Rick, but she still genuinely loved her family deep down. By season 3, she's become a full-blown narcissist who would literally rather die than be bored, and who only cares about her children insofar as it would hurt her ego to be seen as a bad mother. Over the course of the season even she realizes this.
241** In the first few episodes, Jerry was a pretty typical sitcom BumblingDad type character, and Rick's disdain for him had more to do with Rick's standards being impossibly high than with Jerry being significantly dumber than average. By season 2 Jerry seems to be going out of his way to prove that Rick was right all along; he's barely capable of functioning in society. However, the Jerry from the early episodes [[spoiler: got left behind in the Cronenberg dimension along with Original Beth and Original Summer in Episode 6 of Season 1; from the little we see of ''him'', he seems pretty competent]].
242** Rick in the early episodes was smart enough to build extremely advanced technologies, but was often not smart enough to control them or get them to work properly. His contraptions often backfired in unexpected ways, like his potion in "Rick Potion #9" unintentionally turning people into horrific mutant monsters. By season 3 his genius has been exaggerated to the point that he's effectively an omniscient god amongst men whose only limitation is that he's too apathetic to use his powers most of the time.
243* ''WesternAnimation/Rugrats1991'':
244** The series cleverly avoided this trope for the most part with the exception of the baby speak, which is very strange for a {{Long Runner|s}}, 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 the point where he is scared of "the guy on the oatmeal box".
245** 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.
246** Stu Pickles is a BunglingInventor with a child-like mindset and an occasional lack of common sense. In the last few seasons, he is portrayed as [[ManChild a highly energetic child in a man's body]], some of the best examples being when he gets really angry and throws his shoes away like he's a child in "Bad Shoes" or when he begs Didi to let him keep Spiffy in "A Tale of Two Puppies". The latter example gets [[LampshadeHanging lampshaded]] by Didi.
247--->'''Didi:''' Three little boys and Spike is more than enough.
248* ''WesternAnimation/RustyRivets'''s SitcomArchNemesis Frankie Fritz started out simply wanting to outsmart Rusty out of jealousy, however later episodes have him trying to wreak havoc around [[CityOfAdventure Sparkton Hills]] for no apparent reason other than [[ForTheEvulz the fact that he can]].
249* ''Franchise/ScoobyDoo'':
250** 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.
251*** Fred's love of the Mystery Machine came to a head in ''[[WesternAnimation/ScoobyDooFrankencreepy Frankencreepy]]'', when it gets destroyed during the first few minutes and sends him into a state of depression for the rest of the film until he tries to replace it with a wooden carriage.
252** In the 1980s series ''WesternAnimation/TheNewScoobyDooMysteries'' and ''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.
253** 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.
254** Scooby-Doo himself was originally just scared easily but ever since ''WesternAnimation/WhatsNewScoobyDoo'' 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.
255** ''WesternAnimation/ScoobyDooMysteryIncorporated'' leaves 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 with a HairTriggerTemper. Scooby also became more of a jerk, feuding with Velma for Shaggy's attention much of the time, rather jarring when one remembers that previous productions like ''WesternAnimation/APupNamedScoobyDoo'' and ''WesternAnimation/ScoobyDooInWheresMyMummy'' portrayed Velma as for all intents and purposes being Scooby's second best friend.
256** Daphne was never as intelligent as Velma, but she wasn't STUPID in the original show, just clumsy. This did not stop ''WesternAnimation/BeCoolScoobyDoo'' from making her a ditzy {{Cloudcuckoolander}} [[{{Expy}} a la]] [[WesternAnimation/MyLittlePonyFriendshipIsMagic Pinkie Pie]] or [[WesternAnimation/GravityFalls Mabel Pines]].
257* Antoine of ''WesternAnimation/SonicTheHedgehogSatAM'' 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).
258** Sonic did however become noticeably 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.
259** Sally in contrast had her positive aspects exaggerated, starting off as a smart but pompous 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.
260* Space Ghost in ''WesternAnimation/SpaceGhostCoastToCoast'' had his {{Cloudcuckoolander}} tendencies, narcissism and occasional bouts of [[HeroicComedicSociopath comedic sociopathy]] dialed up more and more as the series went on, until he went from a hero who's a bit of a {{Manchild}} to a NominalHero who's certifiably insane by the final season.
261** Moltar became more and more of a secondary ButtMonkey in the later seasons, to the point that even Zorak would frequently trash-talk him.
262* ''WesternAnimation/StevenUniverse'' actually for the most part managed to avoid flanderizing its core characters - many that could have very easily been flanderized to the high heavens. Pearl's OCD tendencies and trauma never became her whole character, neither did Amethyst's silliness or Greg's care-free attitude. However, this show was not immue to flanderization:
263** Garnet may have undergone this. Prior to "Jailbreak", she was a blunt, powerful, stoic but caring gem who had a few episodes exploring her personality (such as her getting sucked into a video game or feeling guilty about causing Steven paranoia with her future vision). After TheReveal of her being a fusion, however, most of her personality revolves around being a fusion: she provides exposition about fusion, makes jokes about being a fusion, and didn't have an episode focused on her that didn't in some way deal with fusion until Pool Hopping. This is probably due to how incredibly popular Ruby and Sapphire became after their first appearance.
264** Lapis Lazuli started as a fairly mercurial figure with a lot of justified trust issues. Once she started appearing in episodes that didn't revolve around her story, the writers gave her some DeadpanSnarker moments for another comedic angle. Late into season three, she's become a full-on monotone robot, rarely inflecting and describing things completely bluntly and literally. Compare how she acts in [[Recap/StevenUniverseS1E26OceanGem "Ocean Gem"]] to how she acts in [[Recap/StevenUniverseS3E21Beta "Beta"]]. She does dial it back for ADayInTheLimelight episodes, though. It's implied heavily that she's become depressed, which can't have helped her mood either.
265** Peridot started out as a goofy character with a highly curious and naive nature and a darker and more serious side. However, after season 3 only her goofiness was shown for the most part, and she was mostly only used as comic relief.
266** Used deliberately in the {{Crossover}} [[Recap/StevenUniverseS2E4SayUncle "Say Uncle"]]. Pearl has a tendency to become quite hysterical or very emotional, but the episode takes to a whole new level due to her SanitySlippage from dealing with the oddness of WesternAnimation/UncleGrandpa. This is completely PlayedForLaughs though (like most of the episode).
267** ''WesternAnimation/StevenUniverseFuture'' also deliberately flanderizes Steven. As the season progresses, Steven becomes more and more unscrewed and prone to major meltdowns and lashing out. This is done to the point it becomes his whole character and all his optimistic and happy traits Steven was known for in the original show are lost. This is done to show Steven's descent into madness and to show what can happen if mental health issues go unchecked. His unchecked trauma and mental health crisis consume and ''become'' his character until he is able to finally get the help he needs.
268* 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.
269** 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.
270** 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.
271* ''WesternAnimation/TeenTitans2003'':
272** 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.
273** 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.
274** 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.
275* ''WesternAnimation/TeenTitansGo'', being a ''[[LighterAndSofter much]]'' [[DenserAndWackier less serious program]], flanderized all the characters from the original ''WesternAnimation/TeenTitans'' into caricatures of their former versions.
276** Robin went from being a stern leader to a total killjoy with SmallNameBigEgo tendencies.
277** Starfire's naivety and Raven's snarkiness (alongside her hidden cute secrets) were upped, with Starfire adding "the" in a lot of her sentences.
278** Beast Boy became an immature, whiny, destructive couch potato; he and Cyborg had their jokester attitudes flanderized into being complete idiots.
279* 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".
280** ''Turtles Forever'' flanderizes almost ''everything'' about the original show. In one scene the '80s Turtles (while in the 2k3 world) proceed to casually walk the streets in broad daylight, go to a pizzeria and order pizza. Predictably every person who sees them runs away in terror and yet the '80s Turtles have no idea why. While their 2k3 counterparts did spend much more effort hiding themselves from the public, in the '80s show the Turtles were aware that the average person would be scared by the sight of mutant, human-sized turtles and hence never went outside without at ''least'' a [[PaperThinDisguise minimal attempt to disguise themselves]]. Also while many of the [[MonsterOfTheWeek enemies]] of the '80s show might seem somewhat silly compared those of the 2k3 show, none of them are as absurd as the one shown in the film running around the world of the '80s Turtles: [[MakesJustAsMuchSenseInContext a walking, talking anthropomorphic banana]].
281** '80s Shredder and Krang are flanderized 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 (incompetent 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.
282** 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.
283** 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.
284** 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.
285** 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]].
286** Raphael went from a grumpy DeadpanSnarker to a {{Jerkass}} PungeonMaster.
287* Many characters on ''WesternAnimation/ThomasAndFriends'' 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 smokebox 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.
288** 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.
289** 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 AttentionWhore who tries in vain to keep the others' respect.
290** 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 dorkier 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 tendencies as Edward and frequently conveying self-esteem issues or cowardice.
291** Thomas himself underwent three flanderizations.
292*** He started out as a snarky and arrogant trickster in the first two seasons. His first flanderization in Season 3 made him nicer and friendlier, although he still has his moments of arrogance.
293*** His second flanderization, which was first noticeable in Season 9, got more noticeable in Season 10 and became really apparent in Season 12 turned him into a CloudCuckooLander who never listens to Sir Topham Hatt or anyone else and leaves disaster in his wake as he either tries to do something he thinks will benefit someone else or thinks that he knows a better way of doing his job.
294*** His third flanderiztion in the All Engines Go! reboot turned him into a childish version of himself with selfish tendencies.
295*** Compare Thomas in the TV series to his original depiction in Literature/TheRailwaySeries. Yes, Thomas in the books can be a naive go-getter, but he can also easily become the co-worker from hell at the drop of a hat. Especially on his branchline in the books, Thomas has a vitriolic relationship with Percy, Toby, and Daisy, sometimes wrongly seeing himself as their superior since he was on the line ''first.'' Played for laughs in stories such as in "Ghost Train" where Thomas's ego is knocked down a peg by his fellow engines, with Thomas begging the Rev. Awdry in the book's opening passage to not include ''that'' story in the finished book and Awdry dismissing it as Thomas being cocky.
296*** Another aspect from The Railway Series that the TV show doesn't include is Thomas' aging. He is nearly 100 years old by the end of the series, and his attitude has changed from a cocky young engine to a CoolOldGuy, an aspect that is never depicted in the TV series.
297** The Fat Controller/Sir Topham Hatt also underwent two flanderizations.
298*** He was originally a firm-but-fair authoritarian who was coyly aware of what his engines were up to most of the time.
299*** In Seasons 8-16, he became more of a background figure who only appears to give the engines jobs and to tell them when they've done something wrong.
300*** In Seasons 19-24, he became a clumsy oaf who embarrasses himself in almost every scene he's in. It really makes you wonder just how this guy manages to run the NWR on top of everything else that happens on a seemingly daily basis...
301** 'Arry and Bert, the steelworks diesels, had an almost nightmarish first appearance in season 5, but by the time they showed up again in season 6, they were minor nuisances. Though they ''did'' regain their nightmarish demeanors for their appearance in season 7, by season 8 they go back to their season 6 characterizations as plain bullies.
302** The narrow-gauge engines have changed pretty drastically from their debut in Season 4 to Seasons 9-12.
303*** Skarloey and Rheneas went from a duo of old and wise engines to a couple of juvenile pranksters.
304*** Sir Handel went from a snobbish and self-centered engine to a wise and helpful one.
305*** Peter Sam went from a naive but hard-working engine who'd occasionally be cheeky to an even ''harder'' worker who never complains or grumbles about late hours or extra work.
306*** Rusty started off as a [[ThePollyanna kind, helpful engine who rarely let personal gripes get in the way of work]], but became much more careless and ruder later on.
307*** A rather unfortunate example is Duncan, who started off as a selfish and arrogant {{Jerkass}}, and after a while of [[TookALevelInKindness becoming nicer and showing more compassion to the other engines]], suddenly reverted back to his original personality once he returned in Season 18, to the point where he always forgets everything he's learned.
308** Henry was always neurotic, but later seasons play up this trait. He can't do a job now without self-doubting himself. Not to the extent of Toby, but he's still a far cry from the strong engine he used to be.
309** A lot of the Flanderization in later episodes can be attributed to the cast passing the SanityBall around. Whoever is the main focus is usually the one getting their shortcomings 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.
310*** Thankfully, much of the flanderization has been reversed in Seasons 17-24. Some added facets (such as Thomas' [[AttentionDeficitOohShiny attention deficit]] and Henry's [[TookALevelInKindness softer personality]]) still remain, though mercifully don't overtake their entire personality.
311* One of the problems with the [[AudienceAlienatingEra audience-alienating]] Creator/GeneDeitch era of ''WesternAnimation/TomAndJerry'' was that back in the original 1940-1958 era, Jerry only used extreme violence if he was protecting himself and when he was a {{Jerkass}}, he was a JerkWithAHeartOfGold. Even if he did attack for no good reason, he would at least get his comeuppannce. However, in the Gene Deitch era, he became a JerkWithAHeartOfJerk with almost no redeeming qualities, was a KarmaHoudini in nearly every short, and liked to see Tom get pummeled by his owner and would never help him. Tom was originally a JerkWithAHeartOfGold but then got reduced to a huge punching bag and more of a {{Jerkass}} as well (he shoots Jerry in the head at the beginning of "Mouse Into Space"). Jerry won in any episode, though it could be argued that Tom wins in "Calypso Cat" because he still pursuits Jerry but that is what Jerry wanted all along.
312** During the Creator/ChuckJones era, Tom and Jerry were restored to their original versions with their "heart of gold" level being raised as there are noticably more episodes where both Tom and Jerry win and several heartwarming endings.
313** Then there's ''WesternAnimation/TheTomAndJerryShow'' which flanderized the characters beyond recognition (they were made into friends. This is why this show is often receieved less positively compare to other shows and shorts.
314** ''WesternAnimation/TheTomAndJerryComedyShow'' had their {{Jerkass}} levels raised but not to the point of the Gene Deitch era. The one-sideness rivalry was restored from the Gene Deitch era, however Jerry actually loses with Tom in a couple episodes and both Tom and Jerry win in "Most Wanted Cat".
315** WesternAnimation/TomAndJerryKids reverted Tom and Jerry to their original 1940-1958 shorts' status. This carried with the rest of the Tom and Jerry franchise.
316* 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.
317** 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 (possibly intended as CharacterDevelopment to show that the Dinobots had come to embrace the Autobots as friends, or maybe they just enjoyed any chance to fight the Decepticons, maybe both). In the third season their badassness evaporated entirely, and went from being DumbMuscle to outright idiots.
318** Fortunately their final appearance in "Call of the Primitives" returned them to their brutish and freakishly-powerful standing.
319* 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 Creator/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]].
320** On the other hand, the original Megatron's unrealistic aim to rule the 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''). Despite this, through his incarnations, he's gone from a laughably incompetent bumbler no different from other 80s cartoon villains like Cobra Commander and Skeletor, to a genuine menace, starting from his DarkerAndEdgier behavior in the original movie to modern interpretations cast him as a darkly magnetic revolutionary turned warlord and often further into an [[TheAntichrist Anti-Prime]] figure, who brands himself with the name of [[SatanicArchetype The Fallen]] and in some way consorts with the powers of [[EldritchAbomination Uni]][[TheAntiGod cron]].
321* ''WesternAnimation/TransformersAnimated'' uses this in-universe with the various Starscream clones. Each one has a certain trait of Starscream's exaggerated to the point where it becomes their entire personality (so while Starscream is a cowardly, egotistical, lying suck-up, Skywarp is afraid of everything, Thundercracker has a massive ego, Ramjet is a perpetual liar, Sunstorm is a complete sycophant, and Slipstream's personality was intentionally left vague).
322* 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.
323* ''[[WesternAnimation/UltimateSpiderMan2012 Ultimate Spider-Man]]'' 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]].
324** 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. Spider-Man was not involved in the episode in ''any'' way.
325** Phil Coulson too; in the Franchise/MarvelCinematicUniverse, he's established by ''Film/TheAvengers2012'' as being something of a [[TheKnightsWhoSaySquee fanboy of Captain America]], 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.
326** Spider-Man himself; usually Spidey is a responsible DeadpanSnarker with an InnerMonologue and the occasional tendency of not thinking through his actions, who defaults to being '[[ComicRelief the funny guy]]' when he teams up with others. The show amps up his comedic traits to the point he's a completely irresponsible IdiotHero with NoFourthWall who can't stop making extremely stupid jokes that are ''very'' irritating.
327* ''WesternAnimation/WinxClub'': Diaspro started as a princess who Bloom attacked with very flimsy justification (she thought Diaspro was Icy in disguise) and only fought back to defend herself. She was also completely unaware her fiance Sky was seeing another woman, and so her anger at being attacked by a total stranger was quite reasonable. However, in her next appearance in the show she was derailed into a {{Jerkass}} {{Yandere}} who eagerly brainwashes Sky in order to marry him and wants to kill Bloom.
328** A reason Season 3 was viewed as SeasonalRot at the time was due to the sudden VillainDecay of the Trix, who were once powerful and competent enough to defeat the entire campuses of two magical schools (and one BadassNormal one) and nearly defeated [[EvilOverlord Lord Darkar]] when he betrayed them. Come season 3 they are easily dispatched over and over again, including by the Winx's ''pixie sidekicks'' at a point. This was received so negatively that when the Trix made a proper appearance again special effort was made to make them a credible threat again.
329* 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. After that episode, though, she reverted to her original characterization, in an unusual reversal of a Flanderization.
330** Master Yo himself. Around the titular rabbits, he would either be just your typical Grumpy Panda that taught them well at Woo Foo, or a lazy, selfish {{Jerkass}}.
