Stan Lane
After leaving the WWWF, Irwin debuted in Championship Wrestling from Florida in December 1978 as "Thor the Viking", with Oliver Humperdink as his manager. While in FCW, Irwin found championship success and wrestled his final match as Thor on October 14, 1979, with a victory over Steve Keirn. The following month, Irwin returned to the CWF as the masked "Super Destroyer", and went on to win a tag team match with Stan Lane against Keirn and Mike Graham.
