Bruce Banner is falling down a bottomless pit back to Midgard when the Enchantress plucks him back. The Warriors Three consult Oldar the Oracle and find out the origins of the Hulk. Banner transforms into the Hulk which enrages the Executioner who has fought the jade giant before. Leaving the Hulk behind, the evil duo lead an army of trolls against Asgard and the Hulk arrives on the scene just in time to lend a hand in the victory of Odin's forces. Even though he has proven himself an ally, the Hulk still manages to tick the All-Father off so an enraged Odin sends him back to earth.
