Warp Star

The Warp Star is a common item in the Kirby series. It first appears in the Mario series as an item in Super Smash Bros. Melee and later appears in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U. 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 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.

Trivia

 * The Warp Star appears in the 2006 version of Nintendo Monopoly, as a station. It takes the place B&O Railroad, and costs $200. In the 2010 version, it was replaced by a Pikmin Onion.
 * In Mario & Luigi: Superstar Saga, Mario, Luigi, Popple and Rookie ride the Beanstar in a similar fashion to how Kirby rides Warp Stars.
 * In Mario & Luigi: Dream Team, Mario is seen riding on a Starman in a similar fashion to the Warp Star. However, Luigi throws it like a frisby and it doesn't actually fly on its own. :
