Having recently snatched the under protected Odinring and therefore being the legitimate ruler of Asgard for the moment, Loki ordered Odin to fall asleep and later convinced Karnilla the Queen of Nornheim to create an humanoid being capable of destroying Thor. That she did, but warned that even her powerful magic could not make such a being actually come alive. Loki anticipated that and, after christening the indestructible warrior as "Durok the Demolisher" ("for demolishing shall be your mission") employed the power he held by way of the Odinring to make the creature alive.
