When the demon-god Loki attacks Valhalla and kills Odin, Odin’s son Thor must escape to the earth-realm of Mitgard (modern-day Los Angeles). With the help of Jarnsaxa, Thor’s guardian demigoddess, he races to find the Hammer of Invincibility in order to stop Loki. Bent on the destruction of earth, Loki descends upon Los Angeles with an army of Garmr (monstrous, man-eating dogs). Thor, armed with the hammer, puts a stop to the destruction. But Loki captures Jarnsaxa and tricks Thor into giving up the hammer.  Loki kills Jarnsaxa, throws Thor into a fiery pit, and summons an army of Lindworms (bipedal reptilian monsters). Armed with the Hammer of Invincibility, Loki begins Ragnarok (Armageddon). But Thor, deep in the fiery pit, summons his god-powers and forges Mjollnir, the true Hammer of the Gods. He rises from the ashes, swinging his hammer down on Loki’s minions. In this epic battle for heaven and earth, only one god will be left to rule all.
