Balder and Thor, while they loved each other as brothers, were always competitive. At a very young age, Balder learned to fight and brawl right alongside Loki and Thor, and was only a little behind his erstwhile brother, Thor, in strength of arms. He grew up in the palace, and accompanied the elder two boys on their adventures, but always was he considered their inferior and lesser. Balder was raised with his Half-Brother, Thor, and adoptive brother, Loki as the youngest of the three, but as a friend, not as a Prince of the Blood.

Technically, this makes him both Vanir and Aesir, though Balder did not know of his parentage until he was much older.

The being known as Balder is the son of Odin and his wife Frigg.
