Malekith the Accursed is a minor villian from the animated television show The Avengers: Earth's Mightiest Heroes episode "The Casket of Ancient Winters". He is voiced by Quinton Flynn.

History
Malekith is a Dark Elves who, along with his people, was destroyed by the Frost Giants ages ago. Loki released Malekith from the realm of the dead, so he would retrieve the ancient artifact known as the Casket of Ancient Winters.

In Norway, he was with the travelers searching something on the ruins of the Viking fort. However, when the others saw frozen figures, they ran and the other one was frozen while attempting to open the crate. Malekith then opened it and obtained the Casket of Ancient Winters.

The Enchantress and the Executioner attempted to grab it from him, he froze them and unleashed the ancient winter on Earth, causing his dead people to rise.

He returns as he claimed that he walked on both worlds of the living and the dead. He posseses the Asgardian artifact, the Casket of Ancient Winters that he unleashes on Earth to resurrect his dead people, create a new paradise for his people and cut of Midgard of the Nine Realms.

But he was stopped by Iron, Thor, and Black Panther who came to stop him. He was destroyed by Thor's lightning strike conducted by Iron Man's armor and the Casket was sealed off for good.
