Warp Star

The Warp Star is a common item in the Kirby series. Its first appears as an item in the Mario series in Super Smash Bros. Melee and Super Smash Bros. Brawl. When a character grabs one, they will fly up into the air, and then crash down to the ground, making an explosion that damages other players (except the player who used the Warp Star).

A Warp Star appears in the Subspace Emissary of Super Smash Bros. Brawl. Kirby and Peach/Zelda use it to escape from the stadium right before it is swallowed by Subspace. However, they are chased by the Halberd, and are forced to land on it.
