The young Thor grew up alongside his step-brother Loki, who was always jealous of Thor, the favored son. Thor excelled in power and popularity, and on his eighth birthday, Odin had the hammer Mjolnir created, enchanting it with powerful magic. He decreed that Mjolnir would be presented to Thor when he had been proven a worthy warrior, and Thor spent the next several years training and performing heroic deeds. Indeed, eight years later, Odin gave the hammer to Thor, declaring him to be the greatest warrior in Asgard.

Powers
As the son of Odin and Gaea, Thor's strength, endurance and resistance to injury are greater than the vast majority of his superhuman race. He is extremely long-lived (though not completely immune to aging), immune to conventional disease, and highly resistant to injury. His flesh and bones are several times denser than a human's.
As Lord of Asgard, Thor possesses the Odinforce, which enables him to tap into the near-infinite resources of cosmic and mystical, enhancing all of his abilities. With the vast magical power of the Odinforce, Thor was able to even dent Captain America’s shield with Mjolnir.
Abilities
Thor is trained in the arts of war, being a superbly skilled warrior, highly proficient in hand-to-hand combat, swordsmanship, and hammer throwing.
