Buzzkill was a small robot that had one mechanical arm which ended in a circular, spinning saw. It was the first robot that Homer Simpson (as Chief Knock-A-Homer) faced in Robot Rumble.
Buzzkill delivered the first blow, hitting Chief Knock-A-Homer's arm with the saw and giving Homer a nasty cut. However, Homer won by grabbing Buzzkill's arm and using the saw to cut him in half, with his own saw. As a victory celebration, Homer yanked the arm out of Buzzkill's remains and swung it in the air.
