Thor (Old Norse: Þórr) is the god of thunder and lightning in Norse mythology, associated with strength, storms, hallowing and fertility. He is the son of Odin and Jörð, the personification of the Earth, and is physically the strongest of the Æsir. Thor is described as being fierce eyed, with red hair and a full beard, and he is quick to anger and has an enormous appetite.
The champion of Asgard, Thor is said to protect both it and Midgard from the likes of the jǫtnar, a race of beings native to Jötunheimr. He is known in Old English as Þunor (Thunor) and in Old High German as Donar (runic þonar ᚦᛟᚾᚨᚱ), all of which stem from the Proto-Germanic *Þunraz, meaning "thunder".
He is married to the golden-haired goddess Sif, with whom he has a daughter, Þrúðr. With his jötunn lover Járnsaxa, Thor has two sons, Móði and Magni. He has a stepson, Ullr, who is Sif's son by a previous marriage.
It was fashioned for him by the dwarven brothers Eitri and Brokkr, and is said to be the most powerful weapon in all the Nine Worlds, capable of crushing even mountains. When Thor threw the hammer, it magically returned to the god's hand.
Other attributes of Thor include a pair of gauntlets known as Járngreipr, which he is required to wear in order to wield Mjölnir, a belt, Megingjörð, which doubles his strength when he wears it, and a staff, Gríðarvölr, which, along with Járngreipr, was given to him by the jötunn Gríðr.
