Cotta Knight is an enemy in the Kirby series that only appears in Kirby and the Rainbow Curse. They are metallic versions of normal Cottas, which means that one can only be defeated by using a Star Dash or by using Bandana Waddle Dee's Charge Attack.
Cotta Knight looks like a grey clay pot with a grey and purple knight helmet on. He also has white eyes and magenta feet. There are also two variations of Cotta Knight; there's Cotta General, which is simply larger, and Spear Cotta Knight, which has small hands for throwing his spear.
