Jobber

Jobbers refer to characters in media that serve a specific niche - losing to (or getting TOYED with) and in turn playing up a threat so that another character can look more powerful when they eliminate said threat. This was the inspiration for the Jobber type introduced in the Pokémon anime. Jobber-type Pokémon are weak to every type, even Bug. Conversely, it is resisted by every type, including itself.
