Thor is married to Sif, a fertility goddess, and he also had a mistress, the giantess Jarnsaxa with whom he had two sons, Magni and Modi and a daughter, Thrud.
Also known as the Thunderer, he was considered to be a son of Odin, but among many tribes he actually supplanted Odin as the favorite god. He is considered to be the protector of all Midgard, and he wields the mighty hammer Mjollnir.
