Assist Trophy (Disambiguation)

Assist Trophy may refer to several Metroid series characters spawned out of the Assist Trophy item in the Super Smash Bros. series:

Additionally, unfinished data in the code of Super Smash Bros. Brawl suggests that Ridley was intended as an Assist Trophy at one point. He appears in the final game as a boss, in Super Smash Bros. for Wii U as a stage boss, and Super Smash Bros. Ultimate as a playable character. Dark Samus becomes playable in Ultimate as well.
