Avenged Sevenfold will launch a new animated series December 15th.

Hail to the King runs six episodes and was directed by Metalocalypse producer Jon Schnepp. It tells the story of the band's long-time mascot Deathbat. The entire series will debut on the Machinima's HappyHour channel on YouTube. A trailer for the series is on YouTube now.

The series is a prologue to the band's mobile video game, Hail to the King: Deathbat, which will be available in early 2014. Avenged Sevenfold frontman M. Shadows says, "Two years ago while touring in South East Asia I looked around the bus taking us from the airport to the hotel and noticed everyone was on their phones and iPads playing different types of games. We had a discussion and decided that it would be fun to create one of our own... We wanted to do something different. Something inspired by some of our favorite games. So we came up with the idea of turning some of our songs and artwork into a living, breathing, evil world."
