As implied by its name, Big Missile is a humongous metal missile. It has yellow eyes and a jagged mouth. It also sports a star logo on its left and right sides, red fins on all sides (connected to the body by springs), and a propeller in the back.
Big Missile only appears in Stage 2 of Lollipop Land and Stage 3 of Royal Road, where it travels straight forward through the air. It will explode if it makes contact with Kirby, a wall, or a projectile. Its size makes it a difficult obstacle to dodge. Kirby can stop it if he has the Hypernova ability; he can try to inhale the Big Missile, attaching it to his mouth. From there, he can spit it in the opposite direction. The missile can plow through enemies, and is ideal for destroying an oncoming Big Missile or the missile's manufacturer.
