Malekith the Accursed is a supervillain in the Marvel Universe. He is ruler of the Dark Elves of Svartalfheim, and has come into conflict with Thor. He once wielded the Casket of Ancient Winters.
Malekith struck an alliance with Loki on behalf of the fire demon Surtur. He took control of a number of Earth humans using special food of the faerie provided by Hela. Malekith then killed Eric Willis, guardian of the Casket of Ancient Winters, after learning its location. As Master of the Hounds, Malekith hunted down Roger Willis, Eric's son and new guardian of the Casket. Malekith battled Thor, and kidnapped Lorelei. Using Lorelei as bait, Malekith forced Thor to battle Algrim the Strong, one of his Dark Elf followers, then attempted to destroy both combatants by plunging them into a pool of magma. He then captured the Casket of Ancient Winters from Roger Willis. Malekith was ultimately defeated by Thor, but not before he destroyed the Casket of Ancient Winters, releasing magical frigid force all over the Earth. Malekith was then brought as a captive by Thor to Asgard.
Malekith later disguised Loki as himself to take his place in the dungeon, while he disguised himself as Balder, who was about to be crowned ruler of Asgard. Kurse, the being formerly known as Algrim, saw through Malekith's disguise when he reached Asgard City. Kurse then broke Malekith's neck, apparently slaying him.
Years later, Malekith was revealed to be alive once again. Disguising himself as Balder again, he enlisted Hercules to attack Alflyse, the Dark Elf Queen of the Eastern Spires, while disguised as Thor. His scheme unraveled (partially due to the appearance of Thor disguised as Hercules), and he was easily defeated by Zeus.
