* ''Anime/SailorMoon'' started ditching the entire supporting cast of the anime (including Usagi's parents and brother) sometime after the second season. All except Usagi's mother completely disappeared in the fifth and final season. As well as her best friend Naru and classmate Umino, whose final appearances are in the direct to DVD special Ami-chan no Hatsukoi at the end of the 4th season. They actually never appear in the 5th season and were already relegated to extras by the 3rd. The [[Manga/SailorMoon manga]] actually ditches them ''even earlier''.
* Doctor Tofu from ''Manga/RanmaOneHalf'', disappeared after the first third of the manga series because his role as MrExposition for weird martial arts was adequately filled by Cologne, one of the [[TricksterMentor Trickster Mentors]] in the series. {{Fanfic}} writers keep using him to provide a second opinion or comedy relief, though there was a joke in the fan community that he had fallen into an open sewer and died. This was only in the manga; he made minor appearances in the anime throughout the series.
* Rumiko Takahashi's earlier manga ''UruseiYatsura'' does this with Princess Kurama: after some time, she disappears altogether. She continues to get small cameos in the anime because of the crowd scenes.
** "Lum's Stormtroopers" disappeared from the manga after Shutaro Mendo showed up, as he more or less filled their roles of being the rival to Ataru. The four [[AscendedExtra became more significant in the anime]].
* Happens {{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.''
* ''[[Anime/ElHazardTheMagnificentWorld El Hazard: The Alternative World]]'' introduced a (seemingly nameless) farmer as a love interest for princess Rune Venus. One episode ended, for him, on a LiteralCliffhanger, about to fall to his doom. However, the cliffhanger was never resolved and [[FridgeHorror the character was never seen (or even mentioned) again]]. Presumably one of the consequences of the series being [[CutShort half as long as originally planned]].
* The Steel Saints from ''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.
* Shamal from ''Manga/KatekyoHitmanReborn''. He got a passing mention in the beginning of Future Arc and is never seen or mentioned anymore.
* Several major characters in ''{{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.
* In ''OnaniMasterKurosawa'', the unnamed younger sister of the protagonist appears in some boxes trying to talk to Kurosawa, only to be solemnly ignored (even by the author, after some chapters).
* ''Manga/YuGiOh'' Manga:
** A character named Hanasaki appears. The characters become friends with him, he's around for some chapters, but after the Death-T arc, he disappears and is never mentioned again.
** Miho Nosaka. She was a very minor character and Honda's love interest in the manga. She gets promoted as a main character in the [[Anime/YuGiOhFirstAnimeSeries first anime series]], but is not in the second series ''[[Anime/YuGiOh Duel Monsters]]''. But she was referenced in [[Anime/YuGiOhGX GX]] when she was listed among the missing Domino residents who are sent to the World of Darkness.
* For a {{Hentai}} with so few characters, it's quite noticeable when Io Azuma in ''MoonlightLady'' simply vanishes.
* This happens a lot in car racing manga. In ''WanganMidnight'', literally ''dozens'' of minor characters, including Rumi Aikawa, Ma, Kochan, Yoshiaki Ishida, Harada, and Makoto Morishita, have been dropped without so much as a footnote.
* Kimi Toudou, {{Kawaiiko}} and shameless GoldDigger from ''FruitsBasket''. The last scene we see with her is her [[FalseStart interrupting a love confession]] between Yuki Sohma and Machi Kuragi while looking for her missing hair brush. She never appears again. This is somewhat surprising as virtually every other minor character in the series makes some sort of appearance for a CleaningUpRomanticLooseEnds chapter at the end. (Even Naohito Sakuragi, equal to Kimi in terms of importance, gets paired off with Motoko Minagawa [the Yuki Sohma Fan Club President] at the end.)
* Klaus in ''Manga/HayateTheCombatButler'' disappeared for around two hundred chapters with absolutely no explanation. Once or twice, it was helpfully noted that, yes, he's still alive.
* This happens to Yuuno Scrya in ''MagicalGirlLyricalNanoha''. He was basically DemotedToExtra in ''[[Anime/MagicalGirlLyricalNanohaStrikerS StrikerS]]'', and then he vanished completely by the time of ''[[Manga/MagicalGirlLyricalNanohaViVid ViVid]]'' and ''[[Manga/MagicalRecordLyricalNanohaFORCE FORCE]]''.
** TheBusCameBack - he reappears for a brief moment in chapter 47 in ''[=ViVid=]''.
* In 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 sister, her lover, or her 10-year-old son from fates worse than death.
* The main character, Tamotsu, from the first ''Boku No Pico'' OVA is never seen or mentioned in the second or third ones.
* Lin's puppy, Pel, from ''Manga/FistOfTheNorthStar'' disappears some time during the Souther arc with no explanation[[note]]only in the anime; it never even shows up in the manga[[/note]]. It shows up one last time in a later episode, only to never be mentioned again.
* 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 no where to be seen and never heard from again, in favor of the actual interesting characters, Dorian Red Gloria and Klaus Heinz Von Dem Eberbach.
* Because the movies are made before the actual series are released, certain characters are left out of the ''Anime/PrettyCureAllStars'' movies. Among them, [[Anime/FreshPrettyCure Eas/Setsuna]] in ''DX 1'' and [[Anime/SuitePrettyCure Seiren/Ellen and Ako]] in ''DX 3''[[note]]It should be noted, though, that Setsuna and Ellen were ''evil'' at the time, while Ako hasn't been officially confirmed as Cure Muse, and was still busy keeping up with the silent protector disguise[[/note]]. Oddly enough, [[Anime/HeartcatchPrettyCure Itsuki and Yuri]] ''do'' show up in ''DX 2'' as [[EarlyBirdCameo brief cameos]], despite Yuri being introduced three episodes after the week the movie was released. [[note]]Although Yuri is noticeably more OOC, not acting like a cold fish she started out as in series proper.[[/note]]
* While most of the characters from ''Anime/{{Beyblade}}'s'' first season came back in season 3, a few players didn't. Steve from ''PPB All Starz'' is replaced by Rick who took Michael's place, and Ivan/Ian isn't a member of the new founded ''Blitzkrieg Boys'' (but he's shown in a flashback with the ''Demolition Boys''). ''Team WHO (the Dark Bladers)'' were never mentioned, and the ''Majestics'' were kicked out by the ''Barthez Battaillion'', and only Ralf/Robert and Johnny got the luck to appear at least in one episode. The teams from season 2 also never appeared in season 3.
* Lunch from ''DragonBallZ'', who disappears along with Tien's first death during the Saiyans' appearances. The author admitted he had forgotten about her. She makes a tiny cameo in the anime, during the Kid Buu Saga, almost ''[[TheBusCameBack 300]]'' episodes later.
* ''SpaceBattleshipYamato'': The NextGeneration characters Kitano and Sakamoto are introduced in ''Yamato The New Voyage''. It appears as if they're being groomed for the positions of Navigator and Cosmo Tiger Flight Leader respectively. Sakamoto is replaced by Shiro Kato (brother of the late Saburo Kato) in the next film ''Be Forever Yamato''. Kaoru Shintani, the ship's cook hasn't been seen since the first series. Hajime Hirata represents the ship's cooking division in ''Yamato III'' although it's not clear whether he is just veteran kitchen staff or the actual head cook.
