First Appearance: Journey Into Mystery #83 (1962)

Played By: Chris Hemsworth

Origins: As punishment for his hubris, Thor is banished from Asgard and put into the body (and memories) of a physically weak medical student on Earth named Donald Blake. With the help of the magical hammer known as Mjolnir, Blake is re-transformed into Thor, the God of Thunder.

Known For: Son of Odin and Gaea, the mightiest of Asgardian warriors and, as a superhero, one of the Avengers, the Marvel supergroup that also includes The Hulk, Iron Man, Captain America, Hawkeye and other heroes.

Powers: Being the son of Odin lends Thor even more strength, stamina and supernatural abilities than even the strongest of other Asgardian warriors. He has amazingly keen senses, can travel through time, resist most diseases and magics, and has ultra-fast healing abilities. He's one tough cookie.
