For ages, Odin has protected his own kingdom of Asgard. But his strength must rest and recover for a single week every winter. In this period, all Asgard's foes (including trolls, giants, dark elves( and demons) attempt to claim the kingdom for their very own, however they are always ceased by Odin's son, the mighty Thor, albeit with the loss of many brave Asgardian warriors. Loki, god of mischief, has kidnapped Dr. Bruce Banner and attracted him to Asgard with the help of both Amora, once Thor's lover, today the super villain called the Enchantress. Loki makes Banner angry and he transforms to the Hulk. The Enchantress then casts a spell across the Hulk which separates his colossal alterego and Banner and grants Loki control.
