Metalocalypse is an American musical adult animated television series created by Brendon Small and Tommy Blacha for Adult Swim. It premiered on August 6, 2006. The television program centers on the larger-than-life melodic death metal band Dethklok, and often portrays dark and macabre content, including such subjects as violence, death, and the drawbacks of fame, with hyperbolic black comedy. The show was widely heralded as both a parody and a pastiche of heavy metal culture.

Brendon Small is an American actor, stand-up comedian, writer, director, producer, and musician who is known for co-creating the animated series Home Movies and Metalocalypse. He also writes the music, and is the main performer for the virtual melodic death metal band Dethklok, which began as the subject of Metalocalypse but has taken on a life of its own, with four albums and an occasional live touring band, headed by Small. Small has also released two albums under his own name, in a similar musical style to Dethklok.
