Warp Star

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

A Warp Star also appears in the Subspace Emissary mode 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.
