Cobra's archenemy, Crystal Boy is a humanoid cyborg with a golden skeleton, and a body made from indestructible glass. He works for the mysterious Pirate Guild. Crystal Boy's signature weapon is a claw he can attach to his right hand. It can crush anything, and he also uses it for slitting his victims' throats. The claw has a built-in laser gun, and can be used as a grappling hook, or fired as a projectile.
