shadow kirby
A dark counterpart to Kirby, making his debut in Kirby and the Amazing Mirror as a shady character who ends up being a valuable ally to the young hero.
He has made numerous cameos and side appearances since then, sometimes even sparring with Kirby like in the Kirby Fighters games. In these games, however, he sports white eyes and a purple, void-like body, as opposed to his usual grey color scheme.
