Coach Carl Carnage is the physical education teacher for Leonardo High School. He is best known for quoting military movies and getting unnecessarily angry at his students for mouthing off.
Coach Carnage once ordered Erik Thiessen to do infinity push-ups, with Biff J. Rockenheimen on his back. The following year, Coach Carnage put Hawk and Croc in charge of organizing the school's halloween party. He thought they did a great job, but was upset that the Halloween party was held on November 07.
