Assist Trophy

An Assist Trophy is an item that, when grabbed, summons a random non-playable character to aid the player who summoned him. Assist Trophies work nearly identical to Poké Balls and Battle Cards. However, no Pokémon or Kingdom Hearts characters 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. Basically they are "guest" characters separate from the playable roster.

Only one Assist Trophy (and the character it releases) can be in a match at once. The next Assist Trophy will not appear until the data for the character it will release is fully loaded.

List of Assists Trophies

 * Amigo: Starts playing with a latin rythme which causes opponents to taunt uncontrolably until he leaves the screen.
 * Bandana Dee: Charges at opponents and jumps around, very weak and can be beaten.
 * Light Yagami: With the help of Misa Amane, who spots one opponent, he uses the Death Note to write the name of the character previously spoted to KO'ing him/her instantly after a 10 second timer has ended. Due to this, he is the rarest AT to appear.
 * Metroid Hatchling: Latches onto an opponent and continually increases their damage for a certain time, can be attacked to prevent it from latching.
 * Pac-Man: Follows the direction of the summoner and chomps the opponents to send them flying with high knockback.
 * Proto Man: Users his Proto Buster (uncharged and charged) while jumping around and dashing across the stage, hitting with his Proto Shield while he is moving.
 * Renji Abarai: Attack with several combos while jumping and running around the stage culminating with his strong Bankai: Hihiō Zabimaru.
 * Starfy: Attacks by performing a series of spinning moves that traps any opponents, a bit weak but hard to knock.
