** Made worse because another episode had them arguing the Doctor was human, not just an AI, when he was denied rights over the publishing of his holonovel for being a hologram.

** In the beginning of "Neutopia" every male Planet Express employee is suddenly sexist, and all the female employees suddenly act like stereotypical women. It probably was just to get the plot going, but still.

** They also had an episode in which the whole family took up smoking, and was over it by the end credits.

** The episode "Fishsticks" has Cartman suddenly have ego problems.

* Rufus of ''TheDreamstone'' spent the majority of the series as an almost sickly sweet HeroAntagonist, however the rare occasion one of the heroes was required to say or do the wrong thing and get handed AnAesop, he would usually take the role. Amberley would sometimes join in on this as well.

** Spike the dragon is normally good, but his envy in ''[[Recap/MyLittlePonyFriendshipIsMagicS1E24OwlsWellThatEndsWell Owl's Well That Ends Well]],'' at the attention Owlowicious is getting, drives him to do some very morally objectionable things, such as planting a fake mouse corpse to try to make it look like Owlowicious killed the mouse. [[note]]When called out on this, he runs away from home, tries to hide in a cave that happens to belong to another dragon... a dragon who seems like he's about to kill or at least severely hurt Spike... but Spike ends up getting saved, [[CrowningMomentOfHeartwarming by Owlowicious. And then Twilight Sparkle reassures Spike he still has an important place in their social circle, prompting Spike to apologize for what he's done]]. By the end of the episode, Spike is pretty much one of the good guys again.[[/note]]

* In ''SonicSatam'' episodes "Sonic and the Secret Scrolls" and "Warp Sonic", the team's [[TheDitherer Ditherer]] and StraightMan Princess Sally becomes as reckless and pompous as Sonic. Punctuated in the former by Sonic randomly taking on a more cautious persona instead.

* ''Series/House of Anubis''- In season 2 Sibuna all admit that they have phobias that make it hard to get through one of the tasks. These phobias came out of nowhere, and were fixed pretty quickly. Alfie's phobia, (Claustrophobia) at least, was mentioned again in season 3,and Amber's bug phobia was mentioned in passing earlier on. But the rest of them? Never mentioned again.

* D.J. had anorexia for 15 minutes on ''FullHouse''. They reduced it to skipping a couple of meals before being saved by Aunt Becky.
** Watch the episode again. D.J. was not anorexic, nor does the show classify her behavior as such. The show points out that her crash-dieting can eventually ''lead to'' developing an eating disorder. She didn't eat for three days straight and was over-exercising, she didn't skip "a couple of meals". And Danny was the one who helped her, not Aunt Becky.

* Eri in ''TensouSentaiGoseiger'' is revealed to be very messy and lazy in Epic 9, causing her to clash with Moune as part of their focus episode. These bad habits are never mentioned before or since.

** Glee does this a lot, honestly. A few other examples include Mercedes developing a borderline eating disorder (cured by a granola bar and a "Don't worry, you're beautiful" talk), Rachel becoming self-conscious about her big nose (cured by a song and dance number), everyone becoming a heavy drinker (cured by solemn talk from Mr. Schue), Ryder suddenly having crippling dyslexia (which isn't cured, it's just sort of... [[VerySpecialEpisode not mentioned again]], Tina all of a sudden being jealous of Rachel (cured when she's promised solos next year, which incidentally never happens).

The plotline has a character display some vice, flaw, prejudice, or other negative attribute/behavior, which said character has ''never before this point'' shown any signs of suffering from, but which they then [[IdiotOfTheWeek engage in solely as the setup]] for some sort of [[VerySpecialEpisode One Shot]] gag or AnAesop. (In some cases, the plot claims/suggests that they've ''always'' had this problem, even though previous episodes show otherwise.) It then vanishes totally after the end of the gag and/or plot. Sometimes this is meant to serve as CharacterDevelopment, but due to the entire process being constrained to that one single episode, it's not very convincing. If the creators are more consistent about the issue, it becomes a largely InformedFlaw which drives several distinct episodes, but still is never observed in a character outside them. Shows up frequently in VerySpecialEpisode, although rarely in the TooSmartForStrangers variant for [[{{Squick}} obvious]] [[GoodFlawsBadFlaws reasons...]]

** In "The Prisoner of Benda" Amy is suddenly an extreme glutton.
*** To be fair, it has been stated a few times that in her younger years, Amy suffered from being noticeably overweight.

* The ''WesternAnimation/SouthPark'' episode "Fishsticks" has Cartman suddenly have ego problems.
[[/folder]]

* Samantha in ''Series/{{Bewitched}}'' experienced pregnancy-related food cravings in a single episode: "Samantha's Curious Cravings".

** "Pulling Double Booty" suddenly reveals that Hayley has severe anger issues when being dumped (by "severe", I mean "rampaging death machine"), even though she was dumped by an illegal immigrant in "American Dream Factory" and harmed nobody (though she did call the FBI to capture him).

** ''[[Recap/MyLittlePonyFriendshipIsMagicS1E16SonicRainboom Sonic Rainboom]]'' takes Rarity's vanity to an extreme that results in her focusing more on showing off her wings than on helping Rainbow Dash. [[note]](Her wings end up falling apart mid-flight; furthermore, Rainbow Dash is the one who rescues her from hitting the ground.)[[/note]]

** ''[[Recap/MyLittlePonyFriendshipIsMagicS2E23PonyvilleConfidential Ponyville Confidential]]'' involves the [=CMCs=] being so insistent on making it big in the school newspaper that they're willing to gossip about their own siblings. [[spoiler:Eventually this backfires on them when Diamond Tiara {{blackmail}}s them with embarrassing photographs of themselves; they decide the best way to deal with this is to come clean to everyone about being the source of the gossip, and by that time the teacher removes Diamond Tiara's authority in the school newspaper anyway.]]

*** A more threatening temporary villainy occurs during ''[[Recap/MyLittlePonyFriendshipIsMagicS2E10SecretOfMyExcess Secret Of My Excess]],'' when his greedy dragon nature gets out of control. When [[spoiler:Rarity, not knowing he is the same Spike, talks about how generous Spike was]], he feels ashamed of what he has become and immediately reverts back to his old self.

** Spike the dragon is normally good, but his envy in [[Recap/MyLittlePonyFriendshipIsMagicS1E24OwlsWellThatEndsWell Owl's Well That Ends Well]], at the attention Owlowicious is getting, drives him to do some very morally objectionable things, such as planting a fake mouse corpse to try to make it look like Owlowicious killed the mouse.

** Twilight Sparkle has this in "[[Recap/MyLittlePonyFriendshipIsMagicS2E3LessonZero Lesson Zero]]", when Twilight is driven insane in her rush to find a friendship problem, to the point where she deviously creates one herself. Her AppleOfDiscord plan, however, [[GoneHorriblyRight goes horribly right]].

* WesternAnimation/MyLittlePonyFriendshipIsMagic: in [[Recap/MyLittlePonyFriendshipIsMagicS2E8TheMysteriousMareDoWell The Mysterious Mare Do Well]], Rainbow Dash's usually harmless tendencies towards being boastful are [[{{Flanderization}} Flanderized]] to insane levels just make an [[AnAesop Aesop]] about humility work.

** Lizzie became a over-the-top GranolaGirl for a few days.

** Leela and Amy are suddenly extremely vitriolic towards one another in "The Butterjunk Effect", when they've got along fine in every other episode.
