A one-shot or one-off character is a character who appears in only one episode of a series, after which they are never seen again. Very common in WalkingTheEarth and various [[IndexOfTheWeek Of The Week]] shows. LongLostUncleAesop from a VerySpecialEpisode is one example, as is the GirlOfTheWeek for any hero who suffers the CartwrightCurse. In a movie, the one-shot can be anything from a SpearCarrier to a OneSceneWonder.

Line numbers and importance to the story don't matter: A one-shot character can be the focus of an entire episode, or just be a BitCharacter. The defining trait is that they show up once and disappear afterward.

Sometimes a one-shot becomes [[EnsembleDarkhorse so popular]] they get TheCameo later in the series, or they become a [[AscendedExtra recurring extra]], or even a [[BreakoutCharacter full-blown cast member]]. Infrequently, what seems like a one-shot may actually be a [[ChekhovsGunman Chekhov's Gunman]].

The opposite would be RegularCharacter. See also RecurringCharacter. The video game equivalent is the UniqueEnemy, which is an enemy that only appears once in a game. [[JustForFun/IThoughtItMeant Not to be confused]] with OneHitPointWonder.
%% Please do NOT add examples; we don't need any, since this is such a universal concept.
