Surtur (Earth-11584)

History
"'You fool! Ragnarok has already begun! Odin no longer sits on the throne of Asgard. You are within my grasp. And when the time is right I shall ascend to your glorious world and burn it to ash.'"Coming Soon...

Powers & Abilities

 * Fire Control: Being a demon made entirely of fire, Surtur could command flames in almost any conceivable fashion. He could fire blasts of flame from his body, increase the ambient temperature over a large area and mentally command flames that were separate from himself (this power was greatly increased when empowered by the Eternal Flame of Asgard).
 * Minion Control: The lord of Muspelheim, Surtur had several creatures and soldiers under his command, most notably Fire Demons (which were viewed more of an extension of himself), the Dire Wolf Fenrir and the dreaded Midgard Serpent.
 * Twilight Sword: The source of much of Surtur's power outside of Muspelheim was the Twilight Sword, which was capable when fully charged of destroying virtually any weapon thrown against it, including Mjolnir.

Weaknesses
Due to a magic spell placed on him centuries ago by Odin, Surtur was bound to the realm of Muspelheim and unable to extend his influence far beyond this breach. Only the power of the Twilight Sword, which took centuries to gain in strength, would eventually allow him to overcome this barrier. This also made the sword his major weakness, as destroying it (or rendering it inert) would mystically transport Surtur back to his domain.
