Season 4 • Episode 12
LatestDethklok is notified of a looming secret that has been around for hundreds of years: the secret of the Metalocalypse. Before they can contemplate what this means, however, Nathan must give a eulogy and do the most brutal thing he has ever done: get in touch with his emotions.
Part-American, part-Scandinavian death-metal band Dethklok has a lingering effect on its fans, who take the words seriously and do anything Dethklok lyrics say. The government fears the band's influence and sets out to destroy it by covert means; for example, by sending military pharmaceutical psychotropic drug manufacturers. Deemed sociopaths for tossing hot coffee at their concert attendees, two of the band members are alcoholics, and they all have self-esteem issues.

Trivia, insights & behind the scenes
Gene Hoglan, legendary drummer for Strapping Young Lad, played Dethklok's live drums. The cartoon band opened for Mastodon and High on Fire for real.
Small pitched it as 'Spinal Tap meets Scooby-Doo' and Adult Swim only greenlit it because they needed cheap programming. It became their longest-running original series.
