Odin is the motherf*cking All-Father. THe highest and most powerful of all Asgardians who toys with stars. Mjolnir was forged from a dying star and Odin seems to have at least oversaw it's construction if not directly involved in some way.
He took Thor's powers. And when he was deemed worthy by self sacrifice, he got his powers and his hammer back. It was a test from Odin.
