Jörmungandr

"In Norse mythology, Jörmungandr meaning "huge monster" also known as the Midgard Serpent is a sea serpent, the middle child of the giantess Angrboða and Loki. Odin tossed Jörmungandr into the great ocean that encircles Midgard. The serpent grew so large that it was able to surround the earth and grasp its own tail. As a result, it received the name of the Midgard Serpent or World Serpent." source: wiki
