Francis X. Clampazzo, better known as Clamps, is one of the recurring antagonists in Futurama. He is robot who is a part of the Robot Mafia and works for Donbot. Clamps is a bronze colored Robot, with a slender body and small door on his torso. He has a row of rivets on the right side of his face, appearing like a scar or stitches. Clamps' personality is paranoid, sarcastic, and highly aggressive, reflecting that of Joe Pesci's character Tommy DeVito in the film Goodfellas, as well as his high pitch, high tempo voice.
