In Norse mythology, Loki symbolizes chaos, mischief, and transformation. He is a complex figure, often straddling the line between friend and foe to the gods. Loki's cunning nature and ability to shape-shift represent the unpredictable elements of life and nature. His actions cause significant consequences, both beneficial and harmful, ultimately leading to the unraveling of the world during Ragnarök, where he plays a pivotal role in the destruction and rebirth of the cosmos.
