The Enchantress, as part of her master Surtur's plan, offers Loki a chance to exact his revenge on Thor and the Avengers for thwarting his conquest of the Nine Realms. She uses a spell to strip Thor, Captain America, and Iron Man of their powers. Now, the helpless heroes must defeat Loki (his soul now in command of a powerful Asgardian weapon known as the Destroyer) without their abilities.
