||The lights of the starry path cross and a Starship appears! Now stop Marx's mad plan!
— Super Star Ultra quote
Kirby's Starship is used in the Nova stage in the Milky Way Wishes stage of Kirby Super Star and its remake. Originally known as the Shooting ability, the Starship forms when the star seals from each star Kirby has visited, which he had also used to summon Galactic Nova, combine, allowing Kirby to chase down Galactic Nova as he tries to grant Marx's wish to control Pop Star. While riding the Starship, Kirby is capable of rapidly firing stars at his opponent and flying at impressive speeds. However, the Starship is not capable of flying through enemies but rather is much better at evading them and bombarding them with star-like projectiles. In Kirby Super Star Ultra, the Starship is also used to fight Kabula, King Dedede's airship guardian.
In Kirby's Epic Yarn, the Starship is one of Kirby's Metamortex transformations. It has the same purpose as it does in Kirby Super Star and Kirby Super Star Ultra, and is similar to the Rocket transformation, only going horizontal rather than vertical.
