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.

Mao Mao, Badgerclops and Adorabat are fearless warriors who protect the people of Pure Heart Valley from monsters, villains and all kinds of bad stuff. Led by King Snugglemagne, the Sweety Pies of Pure Heart are cute, cuddly and pretty much helpless. Luckily, they have valiant heroes like Mao Mao, Adorabat and Badgerclops to watch over them. He’ll battle baddies like the Sky Pirates: Orangusnake, Ramaraffe, Boss Hosstrich and Rat-A-Rang, while learning to become a legend in his own time.
