Útgarða-Loki

In Norse mythology, Útgarða-Loki (Anglicized as Utgarda-Loki, Utgard-Loki, and Utgardsloki) is the ruler of the castle Útgarðr in Jötunheimr. He is one of the jötnar and his name means literally "Loki of the Outyards" or "Loki of the Outlands", to distinguish him from Loki, the companion of Thor. He was also known as Skrýmir or Skrymir.
