The Warp Star (ワープスター, Warp Star), also formatted as Warpstar, is an item appearing in Melee, Brawl and Smash 4 that, when picked up, sends a player flying off into the sky and crashing back down into the stage with an explosion that deals 22% damage and high knockback. It is possible to control the landing location by pressing left or right on the Control Stick while the player is flying. Because of this, it is possible to miss the stage and self-destruct. If a character is hit when the Warp Star is first grabbed, the item can be "dropped" before it can be used. The Warp Star can then be regrabbed and used normally. A shield will not protect against the star's impact (except for a few frames of Yoshi's shield with proper timing when he has invincibility frames), so the only way to avoid damage is to not get struck or sidestep with the correct timing. Since Warp Stars crash into the stage from above, they can be used to "leap" to a higher part of the stage. Therefore, stages with many platforms can limit its effectiveness (and, in the case of scrolling stages with high off-screen platforms such as Rainbow Cruise or Rumble Falls, can even cause an SD). The Warp Star's ability to travel left and right before landing seems to have been diminished from Melee to Brawl. A player is invincible while riding on the Warp Star; if it hits a Bumper, it will pass through it.
Characters riding on Warp Stars can also bounce on shells if they land precisely on them.
The Warp Star has a very large role in the Kirby series. It has appeared in nearly every single Kirby game to date. In every one, it has served as Kirby's mode of transportation. When he touches the Warp Star, Kirby flies it high off the screen, then "crashes" back down in another location. In various games, Kirby is able to summon it with a cell phone. It is stated in the anime and implied in Kirby & The Amazing Mirror that a Warp Star is the trademark of a hero.
Super Smash Bros. Melee Trophy Info
The Warp Star originated as Kirby's ride: it helped the ponderous puffball get around at high speed. Hop on the Warp Star in Super Smash Bros. Melee, and your character will rapidly launch up and off the screen. You'll return in a flash, causing an explosion as you hit the ground. Try holding a direction to alter your landing.
Super Smash Bros. Brawl Trophy Info
A warp-speed item. In the Kirby series, Warp Stars are used to move between stages. In Smash Bros., they're ultrafast attack items that zoom up and down to devastate anyone they hit. You can shift your landing spot by moving the Control Stick left or right during your descent. Choose your target and hang on! Don't overshoot the mark and plummet off the stage, though.
