Loki

Loki is the cunning trickster god in Norse mythology, a shape-shifting blood-brother to Odin who fathers monstrous offspring including Fenrir, Jörmungandr, and Hel. He causes chaos through clever pranks and deceptions, such as cutting Sif's hair or engineering Baldr's death with mistletoe, yet often aids the gods, retrieving treasures or solving crises with his wit. Loki embodies duality—ally and betrayer—culminating in his role as Ragnarök's instigator, bound in chains until he leads the forces of chaos. His fire association and fluid nature symbolize unpredictability, transformation, and the disruptive force of intellect in Norse cosmology.
