The Casket of Ancient Winters is the twentieth episode of Avengers: Earth's Mightiest Heroes. Malekith the Accursed (a dark elf) takes control of the casket, which begins to turn the Earth into a frozen wasteland. Thor, Iron Man and Black Panther must combine forces in order to stop him.
Malekith betrayed Loki by keeping the casket for himself, but when the Avengers stop him, the Enchantress and Executioner got away with the casket for Loki. At the very end, when Thor opens a portal to Asgard, he realized that he mysteriously couldn't return back.
- Hawkeye's remark that they should move out the west coast is a reference to the fact that in the comics, for a time the Avengers were divided into two separate teams on each coast.
