History NeverLiveItDown / WesternAnimation

** Miss Keane often tends to receive flak from some fans due to her punishing the girls for attempting to stop the Gangreen Gang from bullying the other students at Pokey Oaks in "Schoolhouse Rocked" and (Like The Professor above) making the girls take a curfew and causes Townsville to descend into chaos so they'd [[SkewedPriorites stay awake in class]] in "Daylights Savings" despite her normally being a reasonable and friendly teacher in most episodes.

** [[CreepyChild Onion]] is seen as evil by a lot of fans. This is due in no small part to the episode "Onion Trade", which has him wreaking havoc and nearly destroying Beach City with Pearl's replicator, which Steven traded him for a toy that it turned out he stole from Steven in the first place. When the show offers any kind of explanation for Onion's behavior, the explanation is that he's [[AmbiguousDisorder strange]], he's acting out because he's lonely and bored, and his mother openly does absolutely nothing about said behavior (insofar as she's even aware of it; it's unclear whether she knows about any of his actual crimes, which range from theft to ''attempted arson''). He does have some positive traits, but these are often ignored by fans.

** While fan opinions about Mordecai and [[RomanticPlotTumor his shifting romance being the prominent focus]] have been divisive in later seasons, the infamous scene in Season 6's "Dumped at the Altar" where he hijacks Muscle Man's wedding to make an awkward speech about ''his'' relationship issues and attempts to dump CJ in front of everyone in attendance, is considered by many as his worst moment ever. [[WhatTheHellHero He's even been called out on it by his friends as well.]]

* ''WesternAnimation/{{Rugrats}}'':
** Despite Didi Pickles being a well-meaning and loving if not somewhat [[ParentalObliviousness inattentive]] mother, many fans have not forgiven her for replacing Tommy's Reptar merchandise with Goober The Gopher merchandise as well as not calling out a man dressed as Goober for rudely snatching Tommy's Reptar toy away and making Tommy cry in the episode "The Big Showdown"
** [[WesternAnimation/TheRugratsMovie In the movie,]] Many people consider Tommy practically psychopathic for nearly pouring banana baby food on Dil and leaving him in the rain to be taken by the monkeys, even though he quickly becomes remorseful and embraces Dil when he starts crying. It doesn't help that some people state Tommy wanted to murder Dil, even though it's never implied the monkeys would kill him to get the food ''and'' that was not Tommy's intent at all, he just wanted them to adopt Dil.

** Homer is known for strangling Bart, which causes a BrokenBase among the viewers.

** After "Arthur's Big Hit" aired, some viewers started to [[RonTheDeathEater demonize Arthur's parents]] due to them never punishing [[BrattyHalfPint D.W.]] for breaking Arthur's model plane and provoking him into hitting her, despite being pretty reasonable parents most of the time. While they do ultimately [[BrokenAesop contradict the episode's stated moral]] of "violence is never justified" by showing little sympathy to Arthur after he is punched by Binky, they aren't downright ''{{abusive|parents}}'' in any episode of the series, this one included.

** [=SpongeBob=] has been seen as an abusive caretaker for Gary since "A Pal for Gary", where he mistreated the snail for "bothering" Puffy Fluffy, even though the latter was clearly tormenting the former. This is despite [=SpongeBob=] having shown nothing but love for Gary before and since that episode.

** Iggy forcing Arnold to wear bunny pajamas in public in "Arnold Betrays Iggy". Even though he realized his mistake after hearing Sid and Stinky admit to pulling the secret out of Arnold's mouth, Arnold never forgave him, nor did the fans. Even Craig Bartlett himself was ashamed of the episode, and Iggy never made another major appearance again. Sid and Stinky can qualify too, since they were the ones who randomly guessed Arnold's secret about Iggy, and also that they broke the promise they made with Arnold not to give away Iggy's secret. Unlike Iggy, this didn't get the two of them removed from the series.
