Thor

Thor is the blood-son of Odin, the All-Father to the Asgardians, and Jord; also known as Gaea the elder goddess of the Earth. Odin decided that it was time for Thor to learn humility. Odin had Thor surrender his hammer, and then sent him to Earth in mortal guise of a crippled young medical student named Donald Blake. Odin transferred the enchantment enabling Thor to change into mortal form with a tap of his hammer. Thor was a founding member of the team of Earth's mightest heroes -- The Avengers -- and continued to serve with them from time to time throughout the years.

In M.U.G.E.N, Thor has been created by Loganir & Black Dragon.
