Super Destroyer
Irwin continued to use the Super Destroyer character in the CWF throughout the rest of 1979 before debuting in Mid-South Wrestling on November 27, 1980, in a losing effort to Ted DiBiase. Irwin, as the Super Destroyer, returned to Mid-South on April 18, 1981, and won the tag team championship with the Grappler after defeating Dick Murdoch and the Junkyard Dog in the finals of a tournament to claim the vacant title. However, the Destroyer and the Grappler lost the tag team title days later to Murdoch and JYD, on April 27. Soon after the title loss, Destroyer rebounded by winning the Louisiana Heavyweight Championship on May 1. He held the title for over two months before losing it to Bob Roop on July 22. Irwin continued to perform as the Super Destroyer upon joining the Continental Wrestling Association, and soon formed a successful tag team with the Masked Superstar.
