In Norse mythology, Loki (/ˈlɒkɪ/) Anglicized (/ˈloʊki/), Loptr, or Hveðrungr is a godor jötunn (or both). Loki is the son of Fárbauti and Laufey, and the brother ofHelblindi and Býleistr. By the jötunn Angrboða, Loki is the father of Hel, the wolfFenrir, and the world serpent Jörmungandr. By his wife Sigyn, Loki is the father ofNarfi and/or Nari. By the stallion Svaðilfari, Loki is the mother—giving 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.
Loki's relation with the gods varies by source; Loki sometimes assists the gods and sometimes behaves in a malicious manner towards them. Loki is a shape shifterand in separate incidents he appears in the form of a salmon, a mare, a seal, a fly, and possibly an elderly woman named Þökk (Old Norse 'thanks'). Loki's positive relations with the gods end with his role in engineering the death of the god Baldrand. Loki is eventually bound by the gods with the entrails of one of his sons.
