Jormungand, also known as Midgard Serpent or World Serpent in Norse mythology, is a sea serpent who is the middle child of the giantess Angrboa and the god Loki. Odin seized Loki’s three children, Fenrisulfr, Hel, and Jormungandr, and flung Jormungandr into the wide ocean that encircles Midgard, according to the Prose Edda. The serpent became so enormous that he could wrap his tail around the Earth and hold it. The world will perish when he lets go. As a result, he was given the names Midgard Serpent and World Serpent. The deity Thor is Jörmungandr’s greatest foe.
