* {{A|nAesop}}esops about snoring tend to suffer from this, as characters spontaneously develop the habit and then no reference is made to this afterwards. Examples include Joey from ''Series/{{Friends}}'' (Chandler can suddenly hear him through the wall after living with him for five years with no problem), Charles Winchester from ''Series/{{MASH}}'' (due to allergies), and Homer Simpson from ''WesternAnimation/TheSimpsons'' (he suddenly starts snoring loudly after years of sleeping with his wife).
** The Winchester one is at least understandable if you ignore the show's status as a LongRunner and consider it to actually take place within the confines of a stint in a combat zone during the Korean War. Seasonal changes do affect the breathing of some people.

* ''WebAnimation/HappyTreeFriends'': Originally, Petunia was a FlatCharacter that [[TheyKilledKennyAgain mostly served as cannon fodder]]. Then the episode ''Wishy Washy'' reveals that she has a '''severe''' case of SuperOCD and is TerrifiedOfGerms, a trait that wasn't even hinted at [[AllThereInTheManual outside a few online materials]]. From then her OCD seems to come and go every few episodes she's in. Notably, in every episode post-''Wishy Washy'' that brings back her NeatFreak tendencies, it ends up being the indirect cause of her death, whether it be from a ChekhovsGun caused by her [[DidntThinkThisThrough not thinking things through]], or simply ending up at the wrong place at the wrong time.

* Likewise Commander Straker in the ''Series/{{UFO}}'' episode "Sub-Smash". He develops claustrophobia on a submarine despite operating numerous times in spacecraft which should give him similar problems.

* In ''Comicbook/{{Blackhawk}}'' #240 (which is towards the end of the [[DorkAge New Blackhawk Era]]), [[EveryoneLooksSexierIfFrench André Blanc-Dumont]] has been given a crippling fear of beautiful women. He declares himself cured after punching out [[spoiler:a man disguised as a woman]].

* ''WesternAnimation/TheOwlHouse'': Eda had an addiction to Hexes Hold 'Em (a card game) in the episode "[[Recap/TheOwlHouseS1E6HootysMovingHassle Hooty's Moving Hassle]]". While a [[TheGamblingAddict gambling addiction]] is completely in-character for Eda, it was never brought up before this episode and is never mentioned ever again (save for "[[Recap/TheOwlHouseS2E10YesterdaysLie Yesterday's Lie]]" showing that she disposed of all of her decks) and exists solely to make B-plot more prolonged.

** The human crew's sudden (and inconsistent) robot racism in ''Fear of a Bot Planet'' is flagrant.

* ''Machinima/ZsdavAdventures'': Zsdav is usually an easy going and cheerful character. But in ''Karácsonyi külön kiadás'' (''Christmas special'') he is portrayed as grumpy and sour who hates Christmas, just to [[YetAnotherChristmasCarol be visited by three spirits and learn the true meaning of the holiday]].

** They also had an episode in which the whole family took up smoking, and was over it by the end credits. It does go to the trouble of explaining that both Hank and Peggy were apparently smokers at some point in the past, at least. Hank does smoke once, in a much later episode (''Hanky Panky'') during a severely stressful situation.
** The episode "The Honeymooners" depicts Hank's mother Tilly as being selfish, wild, reckless, and out of control, she also cheats on her husband Gary whom she loved dearly and divorced him for a man she just met, the other characters act like she's always behaved this way.

* ''WesternAnimation/ThePowerpuffGirls'' :

* ''WesternAnimation/ThePowerpuffGirls'' episode "Cover Up" reveals that [[TheLadette Buttercup]] psyches herself up to fight crime by privately stroking a green blanket while repeatedly muttering "I am a good fighter". She's so dedicated to this ritual that she's late to helping her sisters save the day, despite flying out with them before and after this episode, and goes hysterical when the blanket disappears. Blossom tricks her with an ordinary rag, and when Buttercup gets back the real one that Professor was actually washing the whole time, her sisters shame her out of dependence. What makes this particularly odd is that Bubbles, who regularly sleeps with a stuffed octopus and keeps a large pile of stuffed animals, [[{{Hypocrite}} is just as judgmental as Blossom]].

* ''WesternAnimation/TheOwlHouse'': Eda had an addiction to Hexes Hold 'Em (a card game) in the episode "[[Recap/TheOwlHouseS1E6HootysMovingHassle Hooty's Moving Hassle]]". While a [[TheGamblingAddict gambling addiction]] is completely in-character for Eda, it was never brought up before this episode and is never mentioned ever again (save for "Yesterday's Lie" showing that she disposed of all of her decks) and exists solely to make B-plot more prolonged.

* ''WesternAnimation/TransformersPrime'': For the sake of HypocriticalHumor at the end of "[[Recap/TransformersPrimeS1E7Scrapheap Scraphead]]" episode, [[WhyDidItHaveToBeSnakes Miko gains a fear of spiders]]. While this phobia is an unusual for humans and even can be considered the stereotype girl fear, it appeared only at the end of this episode and never brought up again. And later Miko doesn't have practically any reaction (let alone fear) to Airachnid, a sadictic spider-Decepticon, so that fear was created for an one-time gag.

* ''WesternAnimation/TheOwlHouse'': Eda got an addiction to Hexes Hold 'Em (a card game) in the episode "[[Recap/TheOwlHouseS1E6HootysMovingHassle Hooty's Moving Hassle]]". While [[TheGamblingAddict gambling addiction]] is competely in-character for Eda, it was never brought up before this episode and never mentioned ever again and exists solely to make B-plot more prolonged.

** "Squirrel Scout Slinkman" has [[OnlySaneMan Slinkman]] suddenly display misoygnistic traits out of nowhere (believing that the Squirrel Scouts are unsuited to physical activity because they're girls, a very strange thing for him to suddenly believe especially since the Squirrel Scouts [[AlwaysSomeoneBetter usually manage to one-up the much wimpier Bean Scouts in everything]]), serving as a justification as to why the Squirrel Scouts decide to torment him in that episode.

* The ''WesternAnimation/CampLazlo'' episode, "Campers All Pull Pants" involves Edward pulling down the pants of every camper in Camp Kidney, with the intention of pantsing Lazlo. In most episodes of the series, [[HalfDressedCartoonAnimal most of the campers don't wear pants, or underwear, for that matter]]. In fact, Edward himself doesn't wear pants and underwear until the episode's climax.

* ''WesternAnimation/JackieChanAdventures'' episode "Relics of Demon Past" has Jade develop a burping habit. While not completely out-of-character for her, it's only there because Jade ends up possessed by the chi of the Wind Demon and her loud, long belches could be weaponized. The burping never showed up before or after this episode.

* In the ''WesternAnimation/StarVsTheForcesOfEvil'' episode "[[Recap/StarVsTheForcesOfEvilS1E10BrittneysParty Britney's Party]]", Star and Marco go to a party that takes place on a party bus, and it turns out that Marco is incredibly susceptible to motion sickness. It's so bad that even when the bus is stopped in traffic he gets ill. This has never been mentioned before or since, not even the times where he rode with his family in their car up to a campsite in "[[Recap/StarVsTheForcesOfEvilS1E6TheOtherExchangeStudent The Other Exchange Student]]" or in the Season 2 episode "Friendenemies" where he partied in a bus, sang karaoke, and even rode around on a white tiger (sort of) with absolutely no problems whatsoever.
