Assist Trophy

An Assist Trophy is an item that, when grabbed, summons a Nintendo character of various origin to quickly aid the holder, though there are currently three third party Assist Trophies. Assist Trophies work nearly identical to Poké Balls. However, no Pokémon come out of them, and once an Assist Trophy is grabbed, it is automatically activated, assuming the holder is standing on the ground, and not in a jump, attack, or hitstun. Some assist trophies must be unlocked in order to be used, such as Isaac from Golden Sun.

Trophy Description
''A capsule that contains characters who will help you out in battle. You won't know who's in the capsule until you open it. It may be someone everyone knows or someone who's a bit of a mystery. The majority of these characters are invulnerable, so attacking them is not an option. You know what that means, right? RUN!''
