** Launch from ''Manga/DragonBall'' disappears after the Piccolo Jr. arc in the manga. According to Creator/AkiraToriyama, this was because [[https://www.kanzenshuu.com/rumor/characters/ he thought he had forgotten about her after writing her out]]. She got a little more screen time in the ''Anime/DragonBallZ'' portion of the anime as filler, but only up to Tien's death during the Saiyan Saga. She also has a tiny cameo in the anime, during the Kid Buu Saga, almost ''[[TheBusCameBack 300]]'' episodes later. This detail was comedically referenced a few times in the ''WebVideo/DragonBallZAbridged'' parody where characters would often ask "I wonder whatever happened to [[DubNameChange Launch]]?" in situations that reminded them of her presence.

* The Steel Saints from ''Manga/SaintSeiya'', characters original to the anime's first season, completely disappeared before the 12 Zodiac Temples Arc. A common joke among the fandom was that they took the wrong plane from Japan to the Sanctuary.

* The ''Anime/HugttoPrettyCure'' movie is one huge CrisisCrossover titled ''All-Star Memories'' that stars all the Pretty Cures for the series' [[MilestoneCelebration 15th anniversary]] -- except for Cure Echo (who debuted in ''[[Anime/PrettyCureAllStars New Stage 1]]'') because of her OriginalGeneration status. She does, however, cameo in an episode that ''promoted'' the film.

* Happens JustForFun/{{egregious}}ly in the ''LightNovel/{{Slayers}}'' novels, more so the ''Special'' series. The most notable example is a mercenary named Lantz, who helps with the fight against Copy Rezo in lieu of [[ThePollyanna Amelia]] in the third novel. He literally runs off, never to be heard of again. The only novel-exclusive character who is returned and remembered is the swordswoman Lemmy, who manages to make it to [[ADayInTheLimelight Amelia's side story]] and a radio drama. In the anime, similarly, Amelia's uncle, Christopher, doesn't get a single mention again after ''Slayers Next.''

* Sheska from ''Manga/FullmetalAlchemist'': After her initial introduction chapters, she has one more brief moment of plot relevance again after Hughes's death, before completely disappearing from the story afterward. Averted in the [[Anime/FullmetalAlchemist original anime]], however, where she remains relevant and forms a friendship with Winry.

* While ''Manga/OnePiece'' normally averts this, one episode of the 4Kids dub was edited that following Luffy's victory over Arlong, the next scene to show him would be of the crew at sea seeing Luffy's first bounty poster, with no mention of what became of Johnny and Yusako and why Nami suddenly became an official crewmate.

* Quite a few characters in ''Manga/OhMyGoddess'' drop out of the series over the course of forty-eight volumes, though some of them are justifiable. Many of the early characters are people who Keichii interacted with as a college student, so once he graduated, he was no longer anywhere that he would be likely to run into Sayoko or Aoshima anymore, and the Motor Club similarly diminished in importance, though since Keichii got a job with a former member, they hung around longer.

*** Finally subverted as of fall 2020, as the original Mewtwo appears in episode 46 of ''Pokémon Journeys'', which reveals he has been protecting several Pokémon who were abused by humans.

* The ''Anime/HugttoPrettyCure'' movie is one huge CrisisCrossover titled ''All-Star Memories'' that stars all the Pretty Cures for the series' [[MilestoneCelebration 15th anniversary]] -- except for Cure Echo (who debuted in ''[[Anime/PrettyCureAllStars New Stage 1]]'') because of her OriginalGeneration status. She does, however, cameo in the episode of ''Anime/HugttoPrettyCure'' that ''promoted'' the film.

* Several major characters in ''Anime/{{Medabots}}'', such as Dr. Aki's niece Karin, never showed up in the second season. The fact that season was made specifically for the US market may have something to do with it.

* ''Anime/SonicX'' has Big the Cat and Froggy, who disappeared after the second season. It's made stranger by the fact that one episode features all the Mobius characters having to go back to their homeworld and Big and Froggy are nowhere to be seen.

* The ''Anime/HugttoPrettyCure'' movie for the fall is one huge CrisisCrossover titled ''All-Star Memories'' that will star all the Pretty Cures over the series [[MilestoneCelebration 15th anniversary]], however, deeper analysis of the trailers reveal that Cure Echo (who debuted in ''[[Anime/PrettyCureAllStars New Stage 1]]'') is nowhere to be seen. Until Toei gives out an official explanation, many has assumed that her OriginalGeneration status is the reason behind her exclusion, which made people assume the worse about her appearance.

** In ''Manga/YuGiOh5Ds'' has Yusei's friend Rally and the other three guys. Yusei's motivation to escape the satellite is partly to improve all of their lives, and he only agrees to enter the Fortune Cup because Rex takes them prisoner. Once the Dark Signers are defeated, they completely vanish until a brief cameo in the second last episode. You'd think they could at least turn out to support their friends at the WRGP. Subverted as Yusei drives past them during his final in-show duel with Jack.

* In ''From Eroica With Love'', the first volume starts out with the main characters established as three psychic powered teens Sugar Plum, Leopard Solid, and Caesar Gabriel. By the end of the first volume, they're nowhere to be seen and never heard from again, in favor of the actual interesting characters, Dorian Red Gloria and Klaus Heinz Von Dem Eberbach.

* Shamal from ''Manga/KatekyoHitmanReborn''. He got a passing mention in the beginning of Future Arc and is never seen or mentioned anymore.

* In ''Manga/MahouSenseiNegima'', Jack recounts the story of how Nagi saved his love interest, Queen Arika, a few years before Negi was born. No one has mentioned her since, and Negi hasn't asked. This also leads to a touch of KarmaHoudini, since Arika has (evidently) never intervened to save her husband or her 10-year-old son from fates worse than death.

** There's an unusual case involving Mewtwo, who hadn't been seen or mentioned since ''The Mastermind of Mirage Pokemon''. Then [[Anime/PokemonGenesectAndTheLegendAwakened the sixteenth movie]] featured Mewtwo as the co-star, except this Mewtwo turned out to be a [[SuspiciouslySimilarSubstitute completely different character]].

* ''Anime/SonicX'' has Big the Cat, who disappeared after the first season. It's made stranger by the fact that one episode features all the Mobius characters having to go back to their homeworld and Big is nowhere to be seen.

* Several major characters in ''Anime/{{Medabots}}'', such as Dr. Aki's niece Karin, never showed up in the second season. That said season was made specifically for the US market may have something to do with it.

*** The video game ''VideoGame/DragonBallZKakarot'' attempts to explain this by saying all of the animal people were the result of everyone taking a drug called animorphaline that turns you into a beastman. And then when the animorphaline fad died, everyone on the planet stopped taking it. Considering how many holes this has [[note]]very young animal people that would have no reason to take this drug or have access to it including babies, animal people being found across the entire planet no matter how remote, King Furry's ancestry, characters like Oolong saying they were born that way, Animal Village etc.)[[/note]] [[VoodooShark this is not a very good explanation]]. [[note]]It doesn't make sense even within just the context of the game itself. The entire plot of the quest in which you learn about animorphaline is that two guys took some, and you have to help them change back. Sounds normal, except that the reason they want to change back is because, since all the other beastmen are gone, they're forced to live in a cave as outcasts due to looking like freaks in the city...except if you actually go to the city, there's actually plenty of beastmen around, and nobody cares. They're also pretty baffled that Oolong is a natural born pig, and say he must have had a rough life because of it, but again, nobody else cares or thinks it's weird that Oolong is a pig.[[/note]]
