Masked Unit

The Masked Unit was a champion fighter in the Ultimate Robot Fighting League. He could transform from a skinny quite simple robot into a large angry fighting machine. He defeated most of his opponents by melting them. His career ended when Bender accidentally knocked him out cold in a movie theatre. When not fighting he is a pleasant polite robot.
