* In ''Theatre/AVeryPotterMusical'', Molly Weasley and Rumbleroar are each in only one scene, but no one is likely to forget either of them.
* [[spoiler: Doctor W.D. Gaster]] from ''WebVideo/UndertaleTheMusical''. [[spoiler:he]] gets ONE song, but it is unforgettable.
As well, [[spoiler: The Six Human Souls]] don't even GET a whole song, and they still stand out as a huge part of the musical.
* Ma-Ti ([[RunningGag from]] WesternAnimation/{{Captain Planet|and the Planeteers}}) gets this honor in ''{{WebVideo/Kickassia}}'' for showing up in one scene of it and calling WebVideo/TheNostalgiaCritic out on his douchebaggery.
* ''Roleplay/SurvivalOfTheFittest''. [[BearsAreBadNews Kenny the Bear.]] That is all.
* Creator/MichaelKeaton would greatly improve 87% of movies by simply appearing according to this Website/TheOnion [[http://www.theonion.com/articles/study-87-percent-of-movies-would-be-better-with-mi,19268/?utm_source=recentnews article]]
* In ''WebVideo/SuburbanKnights'', a girl using a cellphone who the villain stumbles upon and kills got quite some attention from the fandom, ever since her ''one second appearance in the trailer''. [[Creator/DougWalker The director/star]] even discusses her on the DVDCommentary (she is played by an ex-girlfriend of his).
* ''WebVideo/SonicTheHedgehog2SpecialEdition''. Failure Cresh, one of the series' few original characters, appears in only one level for about five minutes (and later gets a brief mention in the epilogue). In this short time, we learn his entire (hilariously) tragic past and see him (mercifully) die. Consequently, he makes a big impression on audiences.
* At the end of WebVideo/TheNostalgiaCritic's review of ''A Simple Wish'', its lead actress Creator/MaraWilson [[https://www.youtube.com/watch?v=pYvgL3lQycY appears to take revenge on him]].
* In the original ''The Gamers'' movie, Mark might qualify. Technically, his character is present everywhere the party goes, but he just stands around looking out into the thin air... Except when he shows up late for game-night, in the middle of a losing battle, immediately goes into a Berserker Rage, slaughters all the enemies alone, then leaves because he's got a date. He was literally only doing anything in one scene!
* ''WebAnimation/RedVsBlue'':
** In season 6, Private Jones, played by Creator/GavinFree, who along with having his name pronounced wrong ("Joannes!" "It's pronounced Jones, sir!") is killed off-screen by Caboose in spite of the latter having his hands tied behind his back.
** In Season 12, the Federation guard who the Reds and Blues fool by disguising themselves as snowmen.
