Malekith

Malekith is the ruler of the Dark Elves from Svartalfheim, known for his mastery of dark magic and his long-standing opposition to Thor and Asgard. He is recognized by his striking appearance, featuring blue and black skin and long white hair, often clad in red with yellow accents. Malekith once wielded the Casket of Ancient Winters, a powerful artifact capable of unleashing intense cold. His role as a cunning and dangerous adversary places him among the key figures in conflicts involving the realms of Norse mythology within the Marvel Universe.
