In Norse mythology, the god of mischief and deception is Loki. Known for his cunning and trickery, Loki often brings chaos to the gods of Asgard. He is a complex figure, sometimes assisting the gods and at other times acting against them, representing the duality of chaos and order in the cosmos. His actions lead to significant mythological events, including the death of the god Baldr and the onset of Ragnarok, the end of the world in Norse belief.
