Jormungandr (mythology)

Jormugandr is one of Loki's children in Norse mythology and a major player in the events of Ragnarok, which was the Norse version of the End Times - though it was not seen as the permanent end of the universe but rather a great battle that would destroy the current world, then make way for a new world with new gods and humans : Jormugandr was one of the apocalyptic beasts who would lay waste to the current world and help in killing off the current gods (known as the Aesir), though would also be slain in the process, allowing for new life to eventually form from the ashes of the old.
