** The Three Powerpuff Girls themselves in "Equal Fights" go through this as the fact of believing the nonsense of Femme Fatale and being influenced by her, since they supposedly do not trust criminals, in addition to saying that she is the only female villain in the whole city, since they already know they had faced female villains before, mainly Sedusa and Princess Morbucks, who have tried to destroy them on more than one occasion. It takes Ms. Keane and Mrs. Bellum talking the trio down do they snap out of it and realize her true nature.

* In one episode of ''WesternAnimation/TeenageMutantNinjaTurtles2003'', during a CrossOver with ''ComicBook/UsagiYojimbo'', we're immediately introduced to samurai Tomoe Ame, who decides at once to flee from the numerically superior foes she's facing. Tomoe in the source material is not only especially "AttackAttackAttack" bloodthirsty, she's known to completely disregard her own safety if she thinks she can take her foes out with her, as ''bushido'' demands. In fact, she's repeatedly refused to back down even when it was much smarter. While there was an explanation [[WatsonianVersusDoylist out of universe]] (MoralGuardians meant that ''she wasn't allowed to use the sword she had with her''), this is downright bizarre to anyone who's familiar with the character.

* ''VideoGame/GoldenSun: The Lost Age'' has Kraden, an elderly scholar who is calm and wise. Throughout the game, you can respond yes or no to some of the questions or propositions he presents. If you say no to him every step of the way and say no to him once the party reaches Lumeria, Kraden will ''completely flip out'' at Felix and yell at him for not taking the quest to save the world seriously. He never does this again.

** "A Pal For Gary" has [=SpongeBob=], who's usually nice and listens to others, even Gary (he even speaks snail), refusing to believe what Gary is telling him, even punishing him for being rude to Puffy Fluffy when it's obviously the other way around. He also lets him suffer Puffy's wrath and be tortured (even when seeing the beast in monster mode), when he's usually a PapaWolf who can sense his pet is in danger or threatened and come to save him in an instant.
** In "Company Picnic", Squidward and Mr. Krabs try to sign a contract with Plankton.

* ''WesternAnimation/{{Teen Titans|2003}}'': An early episode, "Forces of Nature", notably has Slade displaying magical abilities and summoning a huge fire monster...despite being a BadassNormal for the rest of the series.

* ''WesternAnimation/FostersHomeForImaginaryFriends'': Mrs. Foster is the kindly CoolOldLady who founded the eponymous location. She loves everybody, including Mac, so why she decided to [[spoiler:steal all the airline tickets that was going to take many of the main characters to Europe and use them for herself and her friends for no apparent reason, leaving Mac to take the heat for the tickets' disappearance]] in "Foster's Goes To Europe" is anyone's guess.

* In ''VideoGame/{{Onmyoji}}'', the super strict and uptight Hangan has a moment of this in which he acts like an overly excited little kid after his superior Enma promises to reward him whatever he wants if he takes on ''just one more mission'', much to the surprise of everybody else.

* In the ''Series/{{Degrassi}}'' episode "Take On Me" Sean, who is normally a sullen, brooding bad boy, begins to act a lot crazier. A lot like Jon Bender of ''The Breakfast Club'' which was the movie the episode was paying homage to, and Sean was the designated "rebel".

** A more [[PlayedForLaughs humurous example]] occurs in [[Manga/JojosBizarreAdventureStardustCrusaders part 3]]. Jotaro is always TheStoic and hardly smiles at anything or cracks a smile at best. But when the crew (minus Joseph) are [[ItMakesSenseInContext laughing at 2 identical rocks]], Jotaro is laughing his ass off with them. [[https://www.youtube.com/watch?v=As9ScybYxKY&ab_channel=Jos%C3%A9Fino It has to be seen to be believed]]

* In Disney's ''Pollyanna'' (©1960), based on Eleanor H. Porter's 1913 novel of the same title, Pollyanna Whittier, an 11-year-old orphan, comes to live with her wealthy, somewhat aloof aunt, Polly Harrington. Normally, Pollyanna is cheerful and optimistic, but when she meets 10-year-old Jimmy Bean, who is also an orphan, she snaps at him when he shows her what he considers "the best climbing tree in town".

-->'''Jimmy Bean''': There it is. The best climbing tree in town. Isn't it a beauty?

-->'''Pollyanna Whittier''': Well, of all the stupid little juvenile tricks! Do you mean to tell me that you brought me all the way up here just to see a crummy old--a crummy old TREE?!

* In Disney's ''Film/Pollyanna'' (©1960), based on Eleanor H. Porter's 1913 novel of the same title, Pollyanna Whittier, an 11-year-old orphan, comes to live with her wealthy, somewhat aloof aunt, Polly Harrington. Normally, Pollyanna is cheerful and optimistic, but when she meets 10-year-old Jimmy Bean, who is also an orphan, she snaps at him when he shows her what he considers "the best climbing tree in town".

* ''ComicStrip/{{Garfield}}'': Garfield actually [[https://www.gocomics.com/garfield/1979/05/28 said that he likes Mondays]] well after "I hate Mondays" had been established as his CatchPhrase. It's also parodied in [[https://www.gocomics.com/garfield/1981/10/05 this]] strip.
