Lurking in the depths of the seas lies Jormungand, a serpent born of evil during the chaos at the beginning of time. Coiled about the great tree of life, he gnaws slowly at the roots, severing the lifeblood that holds the worlds together. He hungers to destroy the world and return all to the nothingness from whence it came.
Prophesy says that Thor and Jormungand will destroy each other at Ragnarok.
Jormungand is the second of Loki's offspring with a giantess. He's also known as the world serpent due to his enormous size as he's capable of encircling the earth with the head meeting the tail.
