Humanity's greatest heroes battle the gods for the survival of the human race! Once every millennium, the gods assemble to decide if humanity is worthy of its continued existence or if it should be destroyed! When the verdict is destruction, the final battle between the gods and mortal heroes will decide the survival or extinction of the human race--a battle known as Ragnarok! Going into round 8 of Ragnarok, unbelievably, humanity is in the lead with four wins! The gods are outraged--how could this be happening? In order to hold on to that lead, Brunnhilde summons one of humanity's greatest scientists, Nikola Tesla, to bring his scientific genius into the Valhalla arena. With no more room for underestimating their opponents, the gods will be represented in the next round by the most sinister of all their fighters, Beelzebub, the Lord of the Flies, also known as.Satan.
