Assist Trophy

The Assist Trophy is an item in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS, and is set to appear in Super Smash Bros. for Wii U. It calls forth a random character to assist the player who used the item, similar to the Poké Ball item. This is unique in that that the character released is from an actual Nintendo or 3rd Party series, but isn't playable. As a result, it introduces characters who couldn't make the cut as playable fighters. Almost all characters that come out of the Assist Trophy are invincible.

Players must be on the ground to summon an Assist Trophy's character. If a player is attacked and sent flying after grabbing the Assist Trophy, but before breaking it open, they must land before they can call forth the Assist Trophy's character. Only one Assist Trophy can appear at a time, unlike Pok&s.

Trivia

 * In Super Smash Bros. for Nintendo 3DS / Wii U, the Waluigi Assist Trophy is used with the Wario series icon instead of the Mario series icon. This is odd, since Waluigi has never appeared in any Wario games. This has been changed as seen on his Super Smash Bros. for 3DS trophy.
