Surtr (Shin Megami Tensei)

Surt, more commonly known as Surtr, is the gigantic fire jötunn that rules the land of fire, Muspelheim from Norse mythology. He guards the entrance of this realm with his shining sword, Laevateinn, which is said to be brighter than the sun. It is also said to be the creator and the destroyer, as the fires of his realm created the stars of the heavens, and later during Ragnarok, it will rain down fire unto all land.
