In Norse literature, the character Loki is often described as a complex and cunning figure, embodying both chaos and trickery. He is not a conventional villain but rather a shape-shifter who plays dual roles in various tales—sometimes assisting the gods and at other times causing mischief that leads to their downfall. Loki's actions are significant in the events leading to Ragnarök, the end of the world in Norse mythology. His contradictory nature embodies the balance between order and chaos, reflecting the complexities of life and relationships.
