Jormungandr, also known as the Midgard Serpent, is a giant sea serpent from Norse mythology. According to the myths, he is one of the children of the god Loki and the giantess Angerboda. Jormungandr is so large that he encircles the world, biting his own tail, and is often associated with the ocean and chaos. In the mythological narrative, Jormungandr is destined to fight Thor, the god of thunder, during Ragnarok, the end of the world. This battle is significant as it symbolizes the struggle between order and chaos. Jormungandr's presence in the myths highlights the themes of fate and the cyclical nature of life.
