Lug

Lug is a large robot whose main problem with scavenging for parts is that he can never find them in his size. Later in the movie, he is converted into a professional-wrestler robot in order to fight evil robots.

Lug is one of the many robots Rodney Copperbottom meets on his journey to Robot City. He takes care of Aunt Fanny, Fender, Piper, Crank, and Diesel. He helps find voice/sound chips for Diesel. He is voiced by Harland Williams. Unlike other robots who had their names revealed, Lug's name is never mentioned.
