When he and his brothers created the first man and woman, named Askr and Embla, each god gave them gift. Odin gave them the gift of breath. As one of the creators of the universe and father of many of the gods, Odin became known as Alfodur ("Father of All").
Odin was the father of many Aesir deities. His wife and consort was Frigg. By Frigg, Odin was father of Baldr, Höd and Hermod. Odin was the father of his eldest son, Thor, by Jörd (Jord or Fjörgyn (Fjorgyn)), a giantess (some say Frigg was Thor's mother). By another giantess named Grid, Odin was the father of Vidar. Odin was also the father of Vali by Rind, daughter of King Billing.
According to the Nordic myths, he was the chief sky god, replacing Tyr, who was originally the chief gods to the ancient Germanic tribes. He also inherited Tyr's role as god of sky and war. Though Odin was the supreme ruler of the gods and men, in contrast with Tyr, he was not trustworthy, because in several stories, he would break his oaths.
Odin was more popular with noble class and the warriors, than the peasants and working class.

Odin offered wandered the world, accompanied by Vili (Hoenir) and Loki. Loki was often allowed to attend the feast in Asgard, since Odin and Loki were blood brother. In Norse myths, ties through blood-oaths were sometimes stronger than among kin. Loki often helped Odin, but sometimes his mischievous nature caused more trouble and embarrassment to him and the other gods.
Odin was depicted as somber and grim bearded god, who sacrificed one of his eyes, so he could drink from the well of Mirmir (Well of Wisdom). Odin was also described as the god who wore wide-brimmed hat and wearing an eye-patch to hid his missing eye.
Odin carried a spear Gungnir made by the dwarves (sons of Ivaldi), while his ring called the Draupner (Ring of Power) was created by the twin dwarfs, Brokk and Eiti. His symbol was the valknut, a knotted device.

Odin was also the father of Sigi, who was the grandfather of Völsung (Volsung). (See Völsunga Saga). It was he who put the sword Balmung (made by Wayland the Smith) in the mighty oak tree, Branstock. Only Völsung's youngest son, Sigmund, could draw the sword out of Branstock. The sword was supposed to allow the wielder to win all his wars.
