An Assist Trophy is an item found in the Wii video game Super Smash Bros. Brawl. It is similar to the Pokéball item, as when thrown, a character from a Nintendo video game will appear, and will usually have a positive effect for the user who threw it.
Assist Trophy Characters
Super Smash Bros. Brawl
Nintendog — The Nintendog was the first Assist Trophy character revealed. However, it is one of the few characters that aren't positive for either the tosser or his opponents, as the dog will block the screen.
Andross — Based on his appearance in the SNES game Star Fox, he inhales, then blasts opponents with polygons.
Lyn — From Fire Emblem, the first Fire Emblem game to be released outside of Japan, Lyn appears taking a huge slash out of opponents.
Mr. Resetti — A mole from the Animal Crossing series who, just like in the games, gives long and boring lectures, which tend to block either the top half of the screen, or the player damage levels, and sometimes the dialogues interact with certain events in the battle. Like Nintendog, he isn't a positive effect for anyone.
Excitebike — In their pixelized forms, variously colored Excitebikers ride into opponents.
Lakitu and Spinies — Also in their pixelized forms, Lakitu flies across the stage, throwing Spinies down at opponents.
