“Assist Trophies allow you to enjoy even more characters who couldn’t quite make it as playable fighters. You may even see some that only the most dedicated fans will recognize, so you’ll have to look forward to them.”
The Assist Trophy is an item in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / 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 third-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 Poké Balls.
