Surtur

"So like your father. Brave. Strong. And foolish. The Sons of Muspell will ride over your ashes to claim Asgard."

- Surtur to Thor

Surtur was an enormous fiery demon native to the dimension of Asgard. He is the ruler of Muspelheim.

Biography
When Thor had unintentionally let loose the beast known as Mangog, his foster brother Loki told him that the only way to truly defeat the creature would be to infuse his hammer with the metal known as Scabrite, which could absorb large amounts of heat. So Thor ventured into the flaming realm of Muspelheim, Surtur's realm and the one place that was abundant with the Scabrite metal.

It was there that Thor realized that it was Surtur's sword that had the Scabrite he needed. But Surtur wouldn't give it to Thor willingly and he engaged the son of Odin in an intense battle.

Eventually though, Surtur was no match for Thor and his control over wind, thunder, and lightning. Surtur was eventually defeated and Thor destroyed Surtur's sword in order to collect the Scabrite he needed.
