Kaizock (カイゾック Kaizokku?) is a walking wind-up robot pirate enemy from Mega Man 8 and Mega Man & Bass. They are mainly found in the circus/carnival themed stages of Clown Man and Magic Man, respectively, and a few are also present in Pirate Man's stage as well. Some of them walk about on the floor to try to collide with Mega Man, but some swing on trapeze-like cords to throw bombs. In Clown Man's stage, they also attack by sending miniature Kaizocks at Mega Man.
- Their name is derived from the Japanese "kaizoku", which means "pirate".
