Yormungand

Yormungand - In Norse mythology, Jormungand, also known as the Serpent of Midgard or the Serpent of Peace, is a sea serpent and the youngest of the giant Angrboda and the god Loki. According to the Edda in Prose, Odin took the three children of Loki, Fenrisulfr, Hel and Jormungand, and threw Jormungand into the great ocean surrounding Midgard. The snake became so large that it was able to fly around the Earth and grab its own tail. When he frees her, the world will end. As a result, he received a different name - the Serpent of Midgard or the World Serpent. Jormungand's sworn enemy is the god Thor.
