Loki In Norse mythology, Loki is a god or jötunn (or both). Loki’s relation with the gods varies by source. Loki assists the gods, and sometimes causes problems for them. Loki is a shape shifter and in separate incidents he appears in the form of a salmon and a mare. Loki’s positive relations with the gods ends with his role in engineering the death of the god Baldr. Loki is eventually bound by the gods with the entrails of one of his sons. A serpent drips venom from above him that his wife Sigyn collects into a bowl. However, Sigyn must empty the bowl when it is full, and the venom that drips in the mean time causes Loki to writhe in pain. During the events of Ragnarök, Loki is foretold to fight against the gods among the forces of the jötnar. There, he will encounter the god Heimdallr and the two will slay each other.
Loki is the son of Fárbauti and Laufey, and the brother of Helblindi and Býleistr. By the jötunn Angrboða, Loki is the father of Hel, the wolf Fenrir, and the world serpent Jörmungandr. By Sigyn, Loki is the father of Nari and/or Narfi. The stallion Svaðilfari as the father, Loki gave birth—in the form of a mare—to the eight-legged horse Sleipnir. In addition, Loki is referred to as the father of Váli in the Prose Edda.
