A launcher is an object featured in the Kirby series exclusively in Kirby Super Star and its remake, Kirby Super Star Ultra. It resembles a metal rack which lays on the floor in various places and acts similarly to a Cannon, launching any playable character who comes into contact with it in a given direction, left or right, though unlike cannons, the character in question will slowly drop in altitude until touching the ground, where they skid to a halt. When a character is standing on a launcher, they will briefly assume their Guard pose before they are propelled forward. As they fly, they will defeat any enemies they come into contact with.
