When the Cobra strikes, Loki seizes the opportunity to meddle in the lives of Thor and Jane Foster! But the Thunder God has even bigger problems to deal with - we're talking Frost Giant and gigantic demon big! Hulk doesn't have it easy either, when he's summoned to fight in an alien arena -against the cosmic powerhouse known as the Champion of the Universe! And back on Earth, he'll face the horrific nightmare that is Earth's Mightiest Mummies (including a certain bandaged-up Asgardian)! But when Thor and Hulk clash, the fireworks really start - as shown in a classic showdown scripted by none other than Stan "The Man" Lee!
