Believing that the world needed a defender, Thor bestowed powers, similar to his own, onto Grant Farrel. Powers Farrel used to fight crime.
Thor's appearance changed over his five issue run, from blue helmet, blue trunks and cape to a gold helmet and red trunks and eventually no cape and helmet just Farrel with his original hair.
