Beef Supreme is a character in the 2006 film Idiocracy, and the only character in the movie who qualifies as a villain.  He is a famous demolition derby/executioner who uses monster trucks, flamethrowers, and grenade launchers to carry out public executions known as "rehabilitation" in 2505 America, which is overrun by idiots.  When Joe (known by everyone else as "Not Sure") is sentenced to rehabilitation for ruining the economy, Beef Supreme drives a phallic-looking truck called the "Ass-Dozer", but it doesn't fit through the archway leading to the rehabilitation arena and is destroyed by crumbling cement.  He emerges from the rubble with his flamethrower and grenade launcher and tries to blast Joe, but after seeing the successful results of Joe's economic suggestions, President Camacho pushes Beef Supreme aside and gives Joe a pardon.
