Metalocalypse takes you through the band making an album underwater called Murmurder, Dethklok awakening a death troll in Finland, William Murderface’s Birthday among many many other monumental episodes in history as the illuminati-style group called the Tribunal tries to thwart the band by calling in experts like “military pharmaceutical psychotropic drug manufacturers”, “celebrity depression specialists” or various psychopaths that attempt to infiltrate the group.

An amazingly funny series that is a must watch!!
