In Norse mythology, Loki is a god who would change his appearance to deceive others. He is often connected to Asgardian gods Thor and Odin. Loki is destined to kill and be killed by Heimdallr when Ragnarok, or the end of the world, happens.
Loki is the son of the ice giant Laufey, and the father of Fenrir, a giant wolf destined to kill Odin at Ragnarok. Loki is also the mother to Slepnir, who is Odin's eight-legged horse. Loki is frequently identified as the adopted son of Odin, but this is not accurate. Odin found Loki after killing Laufey, but he did not raise him as his son. Although they were not raised together, he and Thor see each other as brothers.
His involvement in the death of Baldr severs his relationship with the gods, and this event sets off the events that lead to Ragnarok
