Read Thor Online Summary:
All the power of the storm, from all the world, flows through my veins, and can be summoned by mine hammer at any time, wherever it is. A lightning storm in Japan? Mine. A hurricane off the coast of Barbados? Mine again. A brace of tornadoes in Kansas? Aye...mine. All that might, all that destructive force, mine to command. Channeled and guided through the mystic might of this hammer, guided right at thee!
Thor is the blood-son of Odin, All-Father of the Asgardians, and Jord, who was also known as Gaea, the goddess who was one of the Elder Gods. Odin sought to father a son whose power would derive from both Asgard and Midgard (as the Earth realm is called by Asgardians), and hence he sought to mate with Jord. Odin created a cave in Norway where Jord gave birth to Thor. Months after the infant Thor was weaned, Odin brought him to Asgard to be raised. Odin's wife, the goddess Frigga, acted as Thor's mother from that time onward. Not until many decades later did Thor learn that Jord was his birth mother.
