Species: nova (kirby)
Novas, also called Clockwork Stars by Magolor, are a mechanical species in the Kirby franchise, constructed by "the Ancients" with the power to grant any wish. They appear to be a pocket watch the size of a small planet with a cat smile.
There are two that have appeared so far, both of whom are major obstacles in their respective games: Galactic Nova in Kirby SuperStar, and Star Dream in Kirby: Planet Robobot.
