Malekith (Earth-11584)

History
"'I hope you enjoyed the Asgardian sunrise Odinson, for it will be the last light you see before the Nine Realms are plunged into Night forevermore.'"Coming Soon...

Powers & Abilities

 * Superhuman Strength and Durability: Due to his Dark Elf heritage, Malekith was supremely strong and durable, on par with most Asgardians (who themselves are far beyond normal humans). This durability also extended to handling Infinity Stones, as Malekith was able to handle the Reality Stone without it destroying his body, as it was doing to Jane Foster.
 * Longevity: Malekith was a young man during the war with King Bor over the Aether, which had taken place several thousand years prior to the present day. As such (even taking into account a prolonged period of hibernation), Dark Elves can be assumed to have a longevity beyond that of Frost Giants or Asgardians.
 * Aether: When equipped with the Aether (also known as the Reality Stone), Malekith could alter the fabric of reality into whatever shape he desired. Normally this effect would be finite or localized, but the power of the stone could be augmented by powerful enough magic and/or science (such as Amora the Enchantress or the Field-Bridge technology.)

Weaknesses
Malekith was overconfident in his own abilities, discounting the powers of Thor, especially after he absorbed the Aether and gained control of an Infinity Stone. However this would prove to be his undoing. Also, despite his longevity, Thor and many other Asgardians likely have a lengthy combat experience advantage over Malekith, given the latter's long term presence in hibernation.
