Notable Victims of Flanderization
NOTE: If highlighted in green, it is positive flanderization.

The Simpsons

 * Ned Flanders (seasons 11-31; The trope namer, as he went from simply enjoying going to church to being obsessively religious and overly nice, and then religious fanatic who will lash out at anyone who doesn't support Christianity.)
 * Moe Szyslak (seasons 16-30; He started as a rather grumpy bartender who will do anything for money, including resorting to do behind the scenes illegal activities that were mostly played as jokes (such as smuggling animals for unknown reasons), and while he was short tempered, he was still a good person at heart, he was simply a grumpy man living in a disappointing life and to improve it, but later on, his actions tend to be more criminal as at one point, he became a registered sex offender, and encouraged alcoholism, and is part of a running gag was he tries to kill himself but fails.)
 * Homer Simpson (seasons 11-30; He went from a dimwitted, yet well-meaning father to a moronic idiot who sometimes acts like a selfish jerk, and became even dumber, and more of an aggressive alcoholic with no control over his emotions, as he would burst into tears or throws fits on a regular basis.
 * Marge Simpson (seasons 16-30; She went from a loving, prepared, down to earth and strict mother to being a really overprotective mother worries too much about everything and is extremely boring and un-impulsive by nature, getting hyped up by household chores and monotonous hobbies. By the HD seasons, she's also become more of a jerk, particularly towards Homer.
 * Bart Simpson (seasons 16-30; He went from a mischievous kid as he loved causing trouble and didn't respect authority, but he wasn't an inherently bad kid, and he had conscience of preventing himself from doing something really bad into a borderline sociopathic jerk, as he didnt care about the health, safety, and lives of anyone, even his own family, as long as he could get some laughs, luckily he still gets his comeuppance for his antics sometimes. He's always recently a likable and lucky jerk against everyone without mercy since the beginning of the series.)
 * Lisa Simpson (seasons 7-30; As one of the earliest cases of flanderization [season 7 premiered in 1995], she went from a level headed foil to Bart and was the smartest and the most well behaved out of the family, and was the voice of reason type of character to a complete know-it-all and a political soapbox as she was start complaining about anything that didn't meet her high standards, and was the only one to protest against the injustices she perceived around her. She's considered recently an unlikable and jealous jerk and the most hated by everyone.)
 * Maggie Simpson (seasons 16-30; She went from a character who occasionally has plot relevance (such as her shooting Mr. Burns in "Who Shot Mr. Burns?"), but she later had some individuality, into simply a background character who only exists for filler. But she didn’t became unlikable here and still remains likable and memorable.)
 * Otto Mann (seasons 16-31; He went from a cool and laid back bus driver to a dangerous low-life and a drug addict.)
 * Patty and Selma Bouvier (seasons 16-30; They went from simply making mean jokes about Homer to being full-on sociopaths who wanted to see Homer suffer. Even going as far as to urge him to jump off a bridge in "Eternal Moonshine of the Simpson Mind" and kidnapping him and locking him in a dirty bathroom in "Wedding for Disaster". Later seasons tone this down though.)
 * Seymour Skinner (seasons 9-30; He went from a reasonably competent, no-nonsense principal who was a Vietnam veteran and had an overbearing mother, and was one of Bart's enemies, as he tried to force authority on Bart, to a pathological and pathetic wimp who at one point, and became even more wimpier as whenever he tries to assert authority on his students, such as Bart.)

Family Guy

 * Peter Griffin (season 8-present; He went from a from somewhat of a bumbling yet ultimately cared about his family, and was incredibly respectful to Meg (one episode involved him saying he'd take a bullet for her) and was also a silly doofus and likable father overall into a malicious, idiotic, monstrous, and incredibly abusive and insensitive psychopath who does illegal and evil things in almost every episode and is always excused for his actions as he's said to do that stuff out of idiocy, even though that's not true. He is also a rotten friend, having shot Joe in the eye and Quagmire in the arm on two separate occasions.)
 * Lois Griffin (season 8-present; She went from a a nice and compassionate wife of Peter Griffin to a short-tempered, immature and psychotic dominatrix wanna-be who sometimes abuses Peter, acts like she has control over her family's life, is a massive hypocrite who calls Peter out on things "she's" guilty of, and is very loud and obnoxious. She's an even bigger Karma Houdini than Peter. One major example was in "Peter-assment", when she says men can't be sexually harrased.)
 * Meg Griffin (seasons 8-14; She went from a a normal girl wanting to make friends to getting routinely abused until she finally snapped, such as trying to plan a sexual assault on Chris just so she could have closure from a gay boy, going all Fatal Attraction on Brian, trying to replace Bonnie as Joe's wife by framing her and breastfeeding their baby, or engaging in a deadly fight at the school cafeteria. However, since season 14 she's been abused less often. Like Squidward, her personality doesn’t change much, just her role as a butt monkey.)
 * Chris Griffin (seasons 8-present; He went from a normal, kind, slightly-dimwitted teenager who is an incredibly talented artist to a completely-dimwitted, uninteresting character who's only known for just masturbating all the time, known for going full idiot mode and is only used when Peter has had too much screen time. But he didn't see too much decline in character, and kept most of his charm.)
 * Brian Griffin (season 8-present; He went from a sarcastic and snarky talking dog who was the voice of reason, and was the most intelligent out of the family to a self-absorbed, pretentious, alcoholic, egotistical douche-bag and "occasionally" atheist fundamentalist (in other words, essentially Seth MacFarlane's political soapbox) that tells lies to get attractive women to like him, thinks religions are purely evil, and their followers are idiots even though not all of them are like that. He is a conniving and ungrateful scoundrel who will do anything to advance any of his careers, especially if it means hurting his loved ones, screwing over the people who helped him, or letting people die. He's also a massive hypocrite by saying Lois having an affair with anyone other than him is wrong. his entire personality now amounts to being a "liberal", and became a complete jerk and got even worse when he came back.)
 * (season 8-present; He went from a toddler with the mind of an evil genius to a toddler with the mind of a stereotypical gay guy, but later returned back to how he was. Depending on your view, however, you could see this as character development since Stewie is no longer evil and has changed his ways, making him seem more likable.)
 * Glenn Quagmire (season 8-present; he went from a funny and somewhat perverted ladies' man to a complete pervert who is used for little more than sex humor and has his perverted qualities exaggerated, and became not just a pervert, but an implied child molester.)
 * Cleveland Brown (The Cleveland Show (season 1); He turned from being a kind, well-meaning guy to being essentially the black version of Peter Griffin, though in season 2 onwards and 12-onwards of Family Guy, he has redeemed himself.)
 * Joe Swanson (seasons 8-10; He went from a strong and confident police officer who was a good role model, and did manage to be a skilled and competent character, despite not being able to walk to a crutch for cruel handicap jokes, an old groaner who screams way too much, and a cowardly spineless cop who lets Peter get away with everything and never arrests him for any lawbreaking acts like shooting Joe in the eye with a BB gun, and for giving his daughter a raspberry in the "wrong place." But unlike most other characters in Family Guy and like Cleveland, Joe’s flanderization wasn't too severe and he thankfully redeemed himself in season 11 where started to go back to his original personality.)
 * Bonnie Swanson (seasons 8-present; In the earlier seasons, she was Joe's caring and supportive wife, but in seasons 8-present, she now sees him as an inconvenience and someone to bully, cheat on Joe and kill him. The biggest example of Bonnie wanting to cheat on Joe is the episode "Foreign Affair" which the main plot of the episode is Bonnie wanting to have an affair in Paris.)

The Amazing World of Gumball

 * (seasons 2-4; Went from a cheerful, naïve, often a loser, childish, kind, and good-hearted protagonist to even more of a stubborn, cynical, sarcastic, reckless, self-centered cheapskate when season 2 kicked in. And in episodes like "The Saint", he can become an outright villain protagonist, from which the old Gumball we all know in love in season 1 normally wouldn't do just that. But he is still enjoyable to watch and became a bit less of a jerk in season 5 and 6. However, he'll eventually revert back to his Keet, sensitive, optimistic, thoughtful old personality with his selfish and egotistical attitude removed in The Amazing World of Gumball: The Series, when it ever gets announced or premieres.)
 * (seasons 2 & 3; Went from a carefree, innocent, dim-witted, humble, and a friendly best friend to Gumball into a real sensitive psychopath who becomes very aggressive and violent to others and often throws his brother right under the bus to stop his antics, at his worst in the episode "The Hero" depending on your view, he chews Gumball out for not encouraging Richard and becomes so spoiled and whiny to the point that he acts like an insufferable crybaby, and get this: he NEVER SHUTS UP! And don't forget about the fact that he became jealous when Gumball is spending more time with Penny than him in the season 3 episode "The Bros". But like Gumball, he's still enjoyable to watch. And he'll revert back to his cheery, air-headed, cloud-cuckoo old personality with his Only Sane Man territory removed altogether in The Amazing World of Gumball: The Series, when it ever gets announced or premieres.)
 * Jamie (season 3-6; Went from a sweet student to a bully in season 3.)
 * Nigel Brown (seasons 2-6; Was first your somewhat forgettable goofball to becoming even more forgetful by the time season 2 rolls around. He is still pleasant to watch.)
 * Sarah (season 3-6; In season 3, she became a huge stalker to Gumball & Darwin, but she is still a funny character.)
 * Alan Keane (seasons 2-6; Went from your average "good kid" to becoming huge Gary Stu with little to no flaws.)
 * Penny Fitzgerald (season 6; Went from a charming likable strong girl to basically becoming the Fitzgerald version of Nicole.)

Garfield

 * Garfield (While in the original incarnations, he was always a jerk, but in The Garfield Show, he became more of an unlikable slob with little to no redeeming qualities. He's also a hypocrite, as he stated in one episode he didn't like bullies, despite the fact that Garfield bullies Odie, Jon, and Nermal all the time.)
 * Jon Arbuckle (He used to be your average joe guy who was a bit bumbling, but now he became more of a bumbling, idiotic, and unlikable jerk who was mean-spirited towards Garfield and later Odie.)
 * Nermal (He was an arrogant, yet cute, innocently gullible and lovable cat into a despicable jerk, even worse than how he's portrayed in the direct-to-video trilogy, basically becoming a mean popular boy. He was at his absolute worst in "King Nermal".)

Teen Titans
IMPORTANT NOTE: Even if the original and Go! Titans are separate entities, as confirmed by ''Teen Titans Go! vs. Teen Titans'', it still shows that the characters were exaggerated beyond recognition from their different incarnation.


 * Robin (Teen Titans Go!) (He tends to act like a dominant and severely paranoid, arrogant jerk, especially towards Starfire, rather than being a strict team leader. Not helping matters is that he is also treated as a Butt-Monkey at times, as his subordinates often act disrespectful to him, even whenever he is in the right.)
 * Starfire (Teen Titans Go!) (She used to a slightly love funning but serious superhero to acting even more immature and childish, and screams a lot in a way as if Hynden Walch is screaming at the top of her lungs. She also adds "the" into many of her lines of dialogue which can be really annoying).
 * Beast Boy (Teen Titans Go!) (Once again, while in the original, he was always portrayed as childish, but he was also quite serious, in this series, he is now an immature, whiny, destructive, literal party-animal teenager and a lazy couch potato who barely gets up to do something simple and barely uses his powers from right.)
 * Cyborg (Teen Titans Go!) (He like Beast Boy, became an annoying and idiotic slacker, with his giraffe neck gag being annoying at times.)
 * Raven (Teen Titans Go!) (She went from a gothic and short-tempered, yet caring to emo, depressed and disastrous, and is more prone to fighting the other Titans whenever they annoyed her, especially Beast Boy. She is the most tolerable of the flanderized Titans, however.

Winx Club

 * Bloom (seasons 5-8; Bloom is basically treated like she can do no wrong, and becomes somewhat of a brat in season five and most notably in season 8, essentially getting upset every time something does not go her way. For instance, she solely blamed Diaspro for ruining her relationship with Sky, despite the fact that 1) Diaspro had no idea who she was 2) Bloom randomly decided she was one of the Trix in disguise and attacked her and 3) Sky was essentially cheating on Diaspro with Bloom, meaning he deceived two people, not just one. Sky is also never held accountable for it. What really sells it, however, is that Sky's father clearly seems to see Bloom as someone rushing headlong into a situation she doesn't understand and upsetting things for specious and self-serving reasons. He's thus cast as a nattering nabob of negativity for letting someone charging around the whole situation like a bull in a china shop.)

Ed, Edd n Eddy

 * Ed (seasons 5 & 6; He went from the muscle of the group who's a bit of a simpleton filled with hilarity to being a too dumb to live-type character who is overly emotional and excessively obsessed with gravy.)
 * Edd (seasons 5 & 6; He went from being the brains of the group who's a bit shy and awkward to being a constantly complaining goody two shoes.)
 * Eddy (seasons 5 & 6; He went from being the self-appointed leader of the group who's a bit devious and ill-tempered yet effectively encouraging with his driving force on giving his friends guidance to being a loudmouthed, problematic, unsympathetic and obnoxious maniac. However, thankfully, he is redeemed in the series finale movie, and finally regrets all his scams.)
 * Jimmy (seasons 2-6; He went from a nice and cute child to a whiny, vengeful and accidental-prone crybaby who always gets pampered by Sarah.)
 * Jonny (seasons 2-6 and in the series finale movie; He went from a loner, yet imaginative and free-spirited kid who was an occasional ally of the Eds, into an annoying, loudmouth and unfunny goofball plus saboteur who can't act or function without Plank's input and presence. In the series finale movie, he being betrayed by the other kids.)

SpongeBob SquarePants

 * SpongeBob SquarePants (seasons 6b & 7 and Patty Pursuit; He went from being a naive, eccentric and somewhat immature, yet optimistic and well-meaning protagonist who has some moments of maturity every now and then to being an even more immature, annoying, outright troublemaking, and obnoxious idiot who is either too happy or a crybaby, and annoys other characters for no discernible reason such as Squidward Tentacles, his restaurant co-worker and one of his two neighbors, and Mrs. Puff, his driving teacher. became an obnoxiously happy moronic idiot and a crybaby in some episodes. However, since season 8, he did redeem himself, and went back to his old personality, due to complaints from fans and critics.)
 * Star (seasons 1b-5; 6-9a; he suffered from two flanderization experiences; he started out as a kind of dumb but fairly intelligent, but as season 1 progressed, he became more stupid and immature and eventually his stupidity became his main, defining trait (this can be seen as good flanderization, as some of his quotes are memorable like "Is mayonnaise an instrument?"). Unfortunately, in seasons 6-8, he had a second flanderization experience (which ruined his reputation temporarily). He essentially became brain dead, with his actions becoming dangerous at times. He also became a selfish jerk. True, Patrick had his jerky and antagonistic moments in earlier seasons, but these moments pretty much became a major part of him in these seasons. Then, in season 9 onwards, he did redeem himself, and went back to his old personality, after years of complaints from fans and critics).
 * Mr. Krabs (seasons 6-10; he went from a greedy yet goodhearted restaurant owner to a more black-hearted and self-serving greedy monster who, in one episode, terrorized Plankton to the point where he attempted suicide (yes, seriously) and Krabs just brushed it off like it was nothing; his love for money also became over-exaggerated, and while he did not fully recover from flanderization in seasons 9 & 10, he is more tolerable than he was in seasons 6-8 until redeeming himself in season 11 onwards).
 * Pearl (seasons 6 & 7; In the earlier seasons, she was emotional, yet still likable teenage girl, but in these seasons, she became an extremely whiny spoiled brat who always wants very expensive things as well as being an annoying crybaby similar to SpongeBob. Speaking of SpongeBob, Pearl does not get along with him very well in these seasons compared to the first five seasons.)
 * Plankton (seasons 6 & 7; became a bigger punching bag than before just like Squidward, where bad things happen to him, even when he doesn't do anything wrong. He's also a less effective villain, particularly in season 6. But most of the time, he is still likable and keeps hs charm).
 * Karen (seasons 6 & 7; In the first five seasons, she was loyal and devoted to Plankton, if a bit snarky at times. In these seasons, she is defined by her snarky demeanor, to the point that she rarely has anything supportive to say to Plankton, even when he's on the brink of suicide. She often gets frustratingly aggressive with Plankton's attempt to outstage Eugene.)
 * Sandy Cheeks (seasons 5-8; She became a lot more obsessed with science than her other traits (eg. karate and Texas), even more so than in season 4, up to the point where she's become a bland, one-dimensional and neurotic science geek with no interesting personality whatsoever. While she did have an interest in science in the first four seasons, it wasn't her defining trait back then. But in these seasons, she wasn't unlikable as she is actually likable and helpful.)
 * Squidward Tentacles (seasons 6-8; He became a constant grouch to everyone and everything around him, showing little care towards SpongeBob or anyone else, though for Spongebob, it could be justified at times. In the earlier seasons, he was quite grumpy, but had a good heart inside and would defend SpongeBob if he was in the right. He is also used as a punching bag in a ludicrous amount of episodes that there are too many to list, see some of them below. In these seasons, as well as the modern seasons, he is often just hurt for no reason, when earlier in the show, he would try to do something bad to SpongeBob but it would backfire and hurt him instead. But in these seasons, he didn't see too much decline in character since he is mostly likable if he is not tortured.)
 * Mrs. Puff (seasons 6-8; She became a much bigger punching bag than she was in the previous seasons (more so on that latter), even if she is unlikable at the correct times, such as Demolition Doofus. But like Squidward and Plankton, she still kept most of her charm and likability.)
 * (seasons 11-present; Became even more loud and accident-prone (yes, accident-prone was one of his defining traits in the earlier seasons, but they were rare, but in this season and onwards, it's seen even more often. However, this is good because it is funny and he gets a lot more screentime in this season and onwards than in the previous seasons.).
 * Background characters/incidentals (Post-movie era; They have become bigger jerks as the series went on, yes, they were always jerks, but they were never this mean, and their jerkish side is shown more often now).
 * Harold (seasons 6-8; He became someone who gets angry even more often than he already did.)

The Fairly OddParents

 * Timmy Turner (seasons 9 & 10; He has gone from a tragic and unpopular, yet goodhearted kid who just wanted his life to be better into a selfish and bratty jerk who only cares about getting what he wants.)
 * Cosmo and Wanda (seasons 9 & 10; went from a cute and loveable fairy god couple with the former being simple-minded, yet charming and the latter being the intelligent, yet voice-of-reason into a generic idiotic husband and nagging wife stereotypes who shared an equal amount of stupidity and carelessness, while frequently losing their wands for what can only be described as plot contrivance.)
 * Mr. and Mrs. Turner (They started out as busy and clueless but soon became extremely negligent parents who have hinted at times that they don't truly love Timmy, and see him as a burden. This was actually the plot catalyst in an episode with a parody of the late Steve Irwin, called 'The Bad Parent Hunter'. While their characterizations were never perfect from the start, they were more tolerable in the first five seasons aka the classic era. Mr. Turner, in particular, has worsen as the show went on, especially in the final two seasons, due to the "Idiot Dad" trope being severely overused on him similar to Cosmo and the fact that he acts like a complete child. Mr. Turner's screen time has also been unbelievably increased in the final two seasons, usually for humor's sake.)
 * Vicky (seasons 6-10; went from a sadistic bully who enjoys torturing Timmy while keeping him safe, to a psychotic killer who wants to outright kill Timmy for no apparent reason while also having a severe reduction in screen time despite still appearing in the intro of the show.)
 * Tootie (seasons 6 & 7; went from a nerdy, yet nice girl who has a crush on Timmy and occasionally helped him to an obsessive, lovesick stalker who constantly harasses Timmy whenever she sees him.)
 * Denzel Crocker (seasons 9 & 10; went from a crazed teacher wanting to prove the existence of fairies to the world into just another annoying manchild like what Mr. Turner has become as well as an incompetent and idiotic villain while being shoehorned into almost every episode, usually for humor's sake like Mr. Turner.)
 * Jorgen Von Strangle (seasons 9 & 10; started out as an intimidating and lawful antagonistic fairy ruler, but as the show went on, he got dialed down to being more of a supporting role. Depending on your view, you may find this as an actual development in character. However, at times, this also made him more of a wimp as evidenced in "Teeth for Two". Then by season 9, he was dumbed down to just a generic plot device whenever the writers needed to bastardize Da Rules.)
 * Foop (seasons 9 & 10; He started out as a villain wanting to destroy Timmy and his fairies in his season 7 debut, "Anti-Poof". But as time went on, he himself has also seen some levels of inconsistency within his characterization here and there, in which he has become less of a villain and more of a pointless moronic comic relief in the same way as Mr. Crocker.)
 * Dark Lazer (seasons 9 & 10; He, like Foop, started out as a villain wanting to destroy Timmy, his fairies, and the town of Dimmsdale, into an incompetent and idiotic villain in one episode in season 10, followed by a typical heel-face turn villain in his remaining two appearances afterward.)

South Park

 * (season 15b & South Park: Post Covid; He became an insensitive person who for once got drug in the "Ass Burgers", become an extremely mean jerk towards Cartman at the beginning of "1%", from which Craig joins with him, and even going so far as calling him baby, when really, Cartman is just 10. And on the other hand, he eventually become so rude and mean-spirited that he acts like another person of Randy Marsh, and stubbornly refuses to go back to South Park since Kyle, Cartman, and even Wendy of all people misses him. Thankfully, he got better in seasons 16-23 and season 25 onward.
 * Gerald Broflovski (season 20; He becomes an unsympathetic asshole who hides being a troll to his whole family, causes the Danish to start the whole Troll-Trace program in the first place by causing Freja Ollegard to commit suicide after trolling her constantly, makes the split of the boys and girls at South Park Elementary (which also causes the boys to turn on Cartman at first), and frames Ike and Kyle for some of his actions. He doesn't even learn a lesson from any of his actions and he gets away scot-free with his trolling.)

She-Ra and the Princesses of Power

 * Catra (seasons 3b-4; Even though she's enjoyable and likeable to watch between seasons 1 and 3a, she became incredibly villainous and increasingly insensitively loathsome between seasons 3b and 4. After all, she was the reason she caused Queen Angella, Glimmer's mother, to be trapped in the portal, exiled Entrapta to Beast Island, became more hostile towards others since the portal incident and treats others disrespectfully, also not taking Scorpia's advice and starts shitting on her, even crosses the line by snapping at her when she broke the recording chip, causing Scorpia to finally turn her back on her, saying she's a "bad friend". At this point, you will believe that she will never be redeemed like this. Even though she did turned her life around in season 5. But still, she isn't exactly off the hook after all of the bad things she's done to Adora.)
 * Glimmer (season 4; Just like Catra, she becomes very bad-tempered and hostile to everyone, such as her increasing resentment of Adora, and Shadow Weaver's influence. She also refuses to rescue Entrapta and threatens to lock up Adora and Bow by using her authority as Queen should they disobey her. She also activated the Heart of Etheria and ends up nearly destroying Etheria in the process. She does recover and realizes the error of her ways and reverts back to her usual, fun-loving and even apologizes to Adora for her hostile behavior in season 5.)

George of the Jungle

 * George (2007; He went from being a bumbling, but strong and loveable hero in the original 1967 series, to then just dumb and childish in the first season, before becoming a literal manchild who speaks in third person with poor vocabulary in season 2.)
 * Ursula (Magnolia in season 2) (She went from being George's love interest in the original 1967 series, to then a tomboyish city girl who was a nice and friendly sidekick to George who wanted to introduce modern culture to the jungle in season 1, before becoming a cynical, obsessive “Rick Sanchez”-esque scientist with a college degree in biology as well as being the huge punching bag of the show in season 2.)
 * Magnolia (Ursula in season 2) (season 2; She became a disgusting, savage predator who not only speaks almost like a primitive caveman, but also barely shows charm and only harms everyone and the environment around her for fun.)
 * Dr. Towell Scott (Dr. Chicago in season 2) (season 2; he went from being a helpful, harmless doctor in season 1 to a mad dentist-turned-scientist who wants to destroy the jungle for no apparent reason.)
 * The Witch Doctor (season 2; Became a stereotypical traditional healer, which some Africans may find offensive.)

Dragon Ball

 * Son Goku (GT and Super; became dumber and more of a manchild)
 * Chi-Chi (Z, GT and Super; became an obnoxiously overbearing mother to her sons, Gohan and Goten, to the point where she attempted to take Gohan's infant daughter away from him as she couldn't stand the thought of her becoming a Z-Fighter when she grew up)
 * Broly (Z: Broly - Second Coming; became a brainless lunatic who did nothing but scream "KAKAROT!" at the top of his lungs)

The Lion King

 * Simba (Simba's Pride and The Lion Guard; A likable and sympathetic hero who became an unlikeable and stereotypical overprotective and over-caring father towards both Kion and Kiara.)
 * Timon (Simba's Pride and The Lion King's Timon and Pumbaa; he becomes more bossy, selfish and unlikable jerk, but thankfully is considered more funny and still likable for fans.)
 * Kiara (Simba's Pride and The Lion Guard; Became an arrogant and snobby brat, and an unlikable teenager.)

Turbo

 * Turbo (season 3, became a person who usually cares about winning and mustaches more so than the first two seasons.)
 * Skidmark (season 3, became crazier than he was in the first two seasons and often cares about hanging out with White Shadow, even more so than the first two seasons.)
 * Burn (season 3, became a greedy and aggressive mean popular girl who lost all of her character development throughout the series and constantly bullies her teammates (even Chet) whenever they mess something up for her or get what she wants, sometimes if by accident and even for petty reasons.)
 * White Shadow (season 3, became dumber than he was in the first two seasons who constantly cares about food than his other trails (e.g. Kung Fu, and racing).
 * Whiplash (season 3, became an even more short-tempered, loud man who often treated the other snails like slaves and also very stupid.)
 * Smoove Moove (season 3, became a lazy slacker Butt-Monkey without any personality as his insecurities get worse, and his team does nothing to help when he gets treated like a punching bag.)
 * Hardcase (seasons 3, became much of a filler generic doomsday villain who once nearly got everyone in Turbotown killed by the stink bomb attracted on the dryer in Turbo Does Laundry.)
 * Dunce (season 3, became a plot device that only served as filler and to keep up with the plots in Turbo-focused episodes.)
 * Mel Shellman (season 3, became overprotective over Charlie too much to the point where he couldn't let the latter get a new best friend.)

Battle for Dream Island

 * Pencil (BFDIA-present; In the first season, she was quite cheery and friendly, but became more of a meaner and a much more bossier leader than before.)
 * Spongy (Battle For BFDI; In the earlier episodes, he was more of a nice person who was disliked by others, but in BFB 12-15, he became more of a jerk, where in BFB 14, he selfishly refuses to let his team in his private jet, when the lava starts flowing in order to get back at them for their actions in BFB 12, and in BFB 15, he simply shoots cannonballs at Puffball just because they were on sale, and he wanted his moneys worth.) Thankfully, he recovered pretty quickly.
 * Book (Battle For BFDI; In BFDIA, IDFB and TPOT, she is shown to be nice, caring, harmless and can be considered to be the voice of reason of the Freesmarters, though in BFB, however, this is where her traits have been butchered completely, as she is shown as an arrogant, immature, obnoxious and moronic idiot who has yet to get over her hatred of Taco who keeps "abandoning" Bleh, though she redeemed herself in both BFB 14 and completely went back to her old self in TPOT.)
 * Match (BFDIA-present; same reason as Pencil)
 * Gelatin (BFB 1-18; He went from an intelligent, kind and sane character who occasionally had selfish moments but was still a good person into a troublesome, irresponsible, immature, and obnoxious idiot who causes trouble, screws up half of the challenges he faces, rarely ever listens to his teammates and Four, and is absolutely untrustworthy and unreliable. He even went by far to act like a spoiled brat in BFB 16)
 * Four (Battle for BFDI 1-29); They seem to become more and more of a selfish and mean-spirited asshole during every passing episode to the point most of the contestants leave the show because of that. Thankfully, they redeem themself by the end of BFB and is now much more tolerable and has less moments of selfishness now.
 * Gaty (Battle for BFDI 15-16, TPOT); Is a jerk to Book after she redeemed herself, was mean to Book when Book was trying to be nice to her again, and didn't let Book on her team in TPOT. She also became a background character to doesn't really do anything interesting, and she still hasn't redeemed herself for being mean to Book.
 * Firey (Battle For BFDI 1-22; became an immature manchild and a really big self-centered jerk who only cares about himself. However, he did redeem himself in BFB 23 afterwards)
 * Foldy (Battle For BFDI 11-13); turned from a nice and caring, plus good asset to her friends with lots of fun moments to a big butt karma fold who only wants to make a team suffer constantly to avenge Stapy and usually causes arguments. She also barely does anything after BFB 11. However, she did redeem herself in BFB 14.

Glee

 * Will Schuester (season 4-5; Became a stubborn, obsessive and pushy manchild.)
 * Rachel Berry (season 2; Became a complete psychopath who never does something without an ulterior motive of stardom.)
 * Tina Cohen-Chang (season 4-5; Became an unlikable diva.)
 * Blaine Anderson (season 3-5; Became an immature manchild.)

Johnny Test

 * Johnny Test (seasons 4-6, he went from went from a rebellious, yet goodhearted boy who helped others, cared about his family, and even had mature moments of learning lessons, and having remorse for his actions whenever they are bad, into a bland and generic spoiled brat who always tries to get what he wants by taking advantage of others and often expresses an apathetic reaction to the disasters he causes in seasons 1-3 he had a smoother character design, voice and was a lot more respectful towards his family including his sister, by seasons 4-6 though he had become a lot more rude, selfish, and an overall generic protagonist.)
 * Susan and Mary Test (seasons 4-6, they went from great teenage partners in training with comedic traits and having the ability to perform intelligent and creative experiments on Johnny to help him out while keeping him safe, into bland and generic teenage girls who constantly drool over boys, most notably Gil Nexdor, with many nonsensical and botched schemes while having little to no regard for Johnny's safety.)
 * Bling-Bling Boy (seasons 4-6; went from a typical, yet cunning villain who would threaten to destroy Porkbelly if Susan doesn't fall in love with him, into a bland and generic villain who makes uncreative and easily foiled schemes to get his hands on Susan, which can get annoying.)
 * Dukey (seasons 5-6, went from a reluctant, yet nice talking dog who can be seen as an older brother-like figure to Johnny to a yes-man Butt-Monkey-type character who, despite pointing out Johnny whenever he is about to do something dumb or otherwise irresponsible, is nevertheless perfectly willing to join in with his friend's antics and, if not, he is easily bribed with meat.)
 * Hugh (seasons 4-6, he went from a firm but fair parent, into a complete overbearing, high-strung, and hotheaded control freak who cares about almost nothing but meatloaf, not even his own kids.)

However, after the reboot he started tolerating his job more, being the comic relief character and a show-stealer)

Scooby Doo

 * Fred Jones (Be Cool, Scooby Doo!; He dialed up to 11 and is stuck in his own ego even more than he was in A Pup Named Scooby-Doo and Scooby-Doo! Mystery Incorporated, where he is into traps. This worsens in the Velma TV show, as he is even more of an egotistical figure than in his previous incarnations, even going as far to be racist towards Velma for no reason, and at times, he is also portrayed as an idiot with little common sense.)
 * Daphne Blake (Be Cool, Scooby Doo!; She is also portrayed as an annoying, bumbling idiot. In Velma, she is portrayed only as a stereotypical high-school student in terms of her mean popular nature)
 * Velma Dinkley (She is now the person hiding in the gang's shadows and no one takes her seriously. And when she has her moments, she is a complete worshipper of technology and science with no moral depths. Her character assassination is at her worst in Velma, her self-titled solo series, as she always makes unfunny and outright forceful fourth-wall breaking jokes for no reason that are usually included only to insult the audience, to pander to political correctness, to try and be funny, to be crude, or to be hip with the youth. In addition, like with Fred in this series, she is sometimes racist (which is ironic given she is race-swapped for the sake of this particular series' plot), is obnoxiously unlikable towards others around her, and is just outright annoying. For example, she falsely accuses Fred for trying to kill her, where he really wanted to pay her to keep quiet about his secret revolving around his puberty.)
 * Scooby Doo and Shaggy Rogers (They became dumber and worshippers of only food; they even disobeyed Velma not to continue eating a food trap in one of the episodes.)

 * Courtney (Total Drama, Total Drama Action onwards; became more aggressive)
 * DJ (Total Drama, Total Drama World Tour; became a cowardish butt-monkey crybaby who complains about an "animal curse")
 * Gwen (Total Drama, Total Drama Action onwards; she was originally a moody and sarcastic yet kindhearted girl, but in "Action", her impulsive actions between her and Trent somewhat caused her to lose Trent as a boyfriend, and in "World Tour", she became more of a jerk, and while she did show some remorse for her kissing Duncan, and when everyone finds out about the kiss, she doesn't vote herself out or apologize, and she tried to manipulate Cody's feelings to vote Courtney off, and in "All-Stars", she became more girly)
 * Duncan (Total Drama, Total Drama World Tour onwards; in World Tour, he became more of a jerk to the point of cheating on Courtney, and in "All-Stars", his soft side gets exaggerated to the point of where he can't stop himself from being nice)

 * Geoff (Total Drama, Total Drama Action; he became more like Chris in the aftermaths)
 * Bridgette (Total Drama, Total Drama Action onwards; became more obsessed over Geoff, and in "World Tour", she couldn't control her hormones to the point where she cheats on him with Alejandro)

 * Sky (Total Drama, Total Drama: Pahkitew Island (episodes 9-ownards), became overly competitive to the point where she threw a fit in the finale)
 * (Total Drama, Total Drama World Tour; Became somewhat hypocritical and a jerk, though this is minor, and can be seen as good by some people)

Thomas and Friends

 * Thomas the Tank Engine (Sharon Miller era, All Engines Go!; He was flanderized twice. He went from a cheeky and fussy, yet optimistic and playful protagonist into a troublesome, irresponsible and unreliable engine who almost never listens to Sir Topham Hatt and frequently causes confusion and delay. Worst of all, when he supposedly learns his lesson at the end of an episode, he completely forgets everything he's learned in the next episode. He did redeem himself in the Andrew Brenner era but suffered from an even worse flanderization in the reboot. Only now, he is portrayed as an even more unreliable child.)
 * Gordon the Big Engine (HiT Model era and seasons 12 & 13, He as went from being an arrogant but kind, wise, and good father figure to Thomas into an immature, arrogant and unlikable character and he has lost all of the original personality and charm he had in the prior seven seasons and hardly saw the light of redemption until season 14.)
 * Toby the Tram Engine (seasons 9-16, he has gone from an old and wise engine to a paranoid wimp who is too scared to do anything.)
 * Edward the Blue Engine (seasons 11 and Sharon Miller era: Just like Toby, he has gone from an old and wise engine to a paranoid wimp who is too scared to do anything.)
 * Henry the Green Engine (Sharon Miller era: He has gone from a kind and friendly gentle giant into a coward who constantly worries too much about every little thing and is too stupid to do anything right.)

 * Emily the Stirling Engine (HiT Model and Sharon Miller era; She has been flanderized twice. She started out as a kind and helpful engine in her debut in season 7, but quckly became a bossy, naggy and selfish one during S8-10. She became a bit more likable in season 11 before being flanderized again in S12-16, where she's become a more unintelligent character.)
 * Skarloey and Rheneas (seasons 9-12, They have gone from old and wise engines into reckless hyperactive children who like to race and fight over taking special trains during seasons 9-12. However, while Skarloey acted like a wimp in seasons 9-11, he acts like a child in season 12, as seen in "Push Me, Pull You".)
 * Sir Topham Hatt (Sharon Miller era, All Engines Go! He has been reduced from a strict, but kind hearted ruler to a pointless comic relief who messes up (e.g. crashing his car three times after carelessly driving on liquid bubble puddles instead of going around them in "Slippery Sodor").)

Bob the Builder

 * Scoop (2015 reboot; He went from a sensible and reliable leader to a clumsy cuckoo clock lander and a careless, useless, idiotic goofball who constantly messes everything up, either unintentionally or on purpose, it doesn't help that he gets too much screentime.)
 * Lofty (2015 reboot; He went from being friendly, shy, sympathetic, and cowardly into being sarcastic, cynical, intelligent and is no longer even scared of anything that much anymore.)
 * Muck (2015 reboot; He went from being a funny but reliable vehicle, into a more dumber idiot who equally screws up everything just like Scoop.)
 * Roley (2015 reboot; He has gone from being smooth and calm with a love of music to being an extremely fussy perfectionist about making sure everything is nice and flat.)

 * Elvis Cridlington (season 6-present; He went from a somewhat dimwitted yet friendly firefighter to an incompetent idiot who is terrible at his job of being a firefighter)
 * Station Officer Steele (season 6-present; He went from a strict and mature authority figure into a silly doofus who has a weird obsession with kids toys)
 * Sarah and James (season 6-present; They went from kind and caring siblings who loved each other no matter what into problematic siblings who fight each other all the time for no reason)

SuperMarioLogan

 * Jeffy (2017-present); While he was stupid & mostly annoying ever since his introduction into the SuperMarioLogan series, he has now become dumber, controversial & imbecilic for infamous reasons, manipulative at times, has become more of a cash cow for SML now, and he has also become a lot more obnoxious with his tediously excessive jokes being more exaggerated than before (so much that it makes Bowser Jr look harmless by comparison in some instances), and such to the point that there were some fans that wanted Logan to burn the Jeffy puppet.
 * Mr. Goodman (2016-present; Went from an decent person to a money-loving, money-hungry jerk towards Mario)
 * Mario (2017-present; He went from a down to earth man living in a house full of idiots to a sometimes stupid yet stereotypical dad and a Butt-Monkey, but is still innocent and likable)

 * Joseph (2017-present; Became an unlikable character whose sole purpose is to be Bowser Junior's annoying Yes-Man, try to look cool and to be on the radical side of things (even if it is genuinely dangerous and questionable), and also became a greedy spoiled jerk on par with The Goodman Family in "Joseph the Millionaire!".
 * Rosalina (2016-present; Became an insensitive, excessively dull-witted, and nagging mother who yells at Mario and defends Jeffy for no good reason. Not even she was immune to flanderization while she was the typical dumb blonde character as well)

Inanimate Insanity

 * Paintbrush (Inanimate Insanity II; went from a responsible contestant who is pragmatic in their approach to challenges and life to an overly competitive, impatient, bossy, and short tempered jerk who often takes things way too seriously. The way they treat Fan in episodes like "Mazed and Confused" and the second part of "Kick the Bucket" also possibly hints that they often overwork any member of the Bright Lights whenever they slack off)
 * Nickel (Inanimate Insanity II; went from a critical character to a selfish and egoistical jerk that made Suitcase paranoid and tried to break up Suitcase and Balloon)

Tamagotchi (TV Series)

 * Memetchi (Tamagotchi TV series, season 1B-present); Although she was always self-conscious about her hair being ruined, it was done in a relatable way, while her flanderization was mostly unseen, in "The Power of Gossip!", she became a bossy and manipulative jerk who would get angry over petty reasons and would throw fits and start arguments for no reason. Not only that, but she became somewhat of a Karma Houdini and gets no punishments for being an asshole to her friends, make gossip to get revenge, lying about her moving somewhere else (although it was seen in her mind), and getting into arguments with her little sister.
 * Kuchipatchi; Although not as terrible as Memetchi's flanderization, he became somewhat more of a Butt-Monkey in this series and became rude or useless depending on the plot.
 * Chamametchi; While she was always an Annoying Younger Sibling trope to Mametchi, she becomes somewhat more talkative in this series, of course, her infamous crying scene could be seen as extremely annoying.

SMG4

 * Axol (late 2020-mid 2021); (he went from a kind and understanding manga artist to a simp who lusts over Melony no matter what, though this flanderization was toned down and his relationship with Melony was developed before he was killed off in WOTFI 2021)

 * Princess Peach (SMG4 2018-onwards); (she became much more bossy, rude, and selfish than her previous personality to the point where in "If Mario was In.. Fall Guys", she punished Mario after Mario gave King Bert, the original owner, the crown instead of her. This showed that she cared about herself, also in "Food Wars", she threatened to kill Mario and his friends for participating at the "party")
 * Toad (SMG4 season 2014 & 2015 & 2018-onwards)(he received two flanderizations; In the first three years, he went from a comedic, mistreated and a slightly grumpy and sarcastic helper, similar to Squidward Tentacles in seasons 1-5 and season 9-present of SpongeBob SquarePants. However, in 2014-2015 he became a crazily obsessed fan of Mario who is addicted to sugar and often played as a poor attempt at comic relief; a complete 180 from his original personality. He would later retain his original personality in the later years, but in 2018-present, he would later become a more grumpy person who would often serve as a punching bag who is heavily mistreated by Toadette (similar to Squidward in seasons 6-8 of SpongeBob SquarePants) to the point of being more mean-spirited than funny)
 * Bowser (SMG4 seasons 2014 & 2015)(he used to be a misunderstood villain of the series who was insecure on the inside. In seasons 4-5, he became a moronic comic-relief who is obsessed with "swag" and "being fabulous" (an easy example of this is in the 2014 episode, "SwagQuest", where he's overly obsessed with making Luigi hip for a swag party at Peach's Castle). Similar to Toad's 2014 & 2015 flanderization, this is typically played as a cheap attempt at comedy.)
 * Fishy Boopkins (mid 2017-present) (he essentially became an anime-obsessed weaboo who in almost, if not every, episode he appears in, he mentions anime or anything related to that)

Half of the time when they are in an episode that takes place in the middle school, they usually tend to sacrifice each others aspirations or talents for their benefits, whether it be all of them or one of them. Despite this, they are still likable characters.)

The Wubbulous World of Dr. Seuss

 * The Cat in the Hat (season 2; started out as a trickster in season 1, but in this season he became more of a Bear in the Big Blue House-like host who gets way too much screen time. He also now has a formulaic tendency to get Terrence McBird to participate in his activities with the Little Cats.)

 * Dave Seville; (became more selfish and strict, though once again he is still likable for the most part)

Sesame Street

 * Elmo (he often gets upset over things, always wants his way, hardly gets any karma for his actions, and started treating Sesame Street's target audience as if they had the mind of a goldfish in a similar manner as other preschool show characters who try to compete with Sesame Street. He has also become a hypocrite since he gets mad whenever Zoe treats her pet rock like a friend, yet he does the same to his pet goldfish Dorothy.)
 * Zoe (seasons 30-46; she became friends with her pet rock named Rocco, despite him being an inanimate object, and becomes obsessed with Rocco)
 * Abby Cadabby (she started getting way too much involved with the show in season 38, despite only appearing in three episodes of season 37. In Abby Cadabby's Flying Fairy School, she also became a punching bag along with Abby, Blögg, Gonnigan and Mrs. Sparklenose. In season 47, she got a stepbrother named Rudy who takes her wand without asking her if he can use it. She can also be useless, like in Episode 4221, for instance.

 * Stuart (Minions and Minions: The Rise of Gru; He became less innocent than he was in the first two films and became rude, grumpy, and a slacker who refuses to follow the rules.)

Cuphead

 * Mugman (The Cuphead Show!; he became an unlikable wuss and an unhinged psychopath and can be a jerk to Cuphead. He is also a hypocrite because at the end of the first episode, he tells Cuphead he owed the Devil his soul but he caused him to do so. Also his dialogue, unlike Cuphead's, is horrendous like "I will not apologize for doing my job.", "A mug without a handle is just a bowl. I don’t wanna be bowl boy", "Nobody asked you, Bowlboy!", and "And you owe the devil your soul.", with Frank Todaro's terrible and annoying voice acting making it worse)
 * (The Cuphead Show! Cuphead, while still very likable as Mugman, has become even more idiotic and impulsive than he ever was in the game, and he's become a Gary-Stu who is loved by just about everyone, however at least he's still likeable, and Cuphead's flanderization isn't as bad as Mugman's.)

Looney Tunes

 * Daffy Duck (1964-1980: He went from being a hilariously screwball egotistical and wacky, yet comically greedy money-loving and spotlight-hungry coward into a grouchy and sadistic, ruthless, irredeemable psychopath with a Yosemite Sam-esque persinality. He also breaks the law and does illegal things just to get a hold of Speedy and abuse him and his mouse friends, with the ABSOLUTE WORST offenders being Well Worn Daffy, Assault and Peppered, and Snow Excuse)
 * The Roadrunner (The Larriva Eleven: He went from being a harmless and simple-minded, innocent bird who tries to outrun Wile E Coyote into a sadistic and malicious annoyance who actively tries to harm the coyote)
