6 Wrestling legends who have appeared only once in AEW 

#5 Greg "The Hammer" Valentine on AEW Dynamite

AEW having wrestling veterans on their shows is nothing new, but Greg 'The Hammer' Valentine is. Greg Valentine is a name wrestling fans are familiar with. The man has had quite a career that harkens back to the 1970s. Greg Valentine was part of Mid-Atlantic Championship Wrestling and was a two-time NWA Mid-Atlantic Heavyweight Champion.

He made appearances in the World Wide Wrestling Federation (WWWF), the precursor to WWF/WWE, and shuffled between them and Mid-Atlantic. Once WWE expanded, Valentine decided to stay with the company and reap the rewards. Valentine would be a WWE Intercontinental Champion, as well as a WWE Tag Team Champion.

Valentine was invited as a special guest for AEW's first-and-only Dog Collar match between Brodie Lee and Cody Rhodes. The match is significant as it ended up being Brodie's last match. But Valentine being in attendance held a greater significance. Valentine and Roddy Piper were the ones who invented this hellacious matchup, with the first occurring at Starrcade in 1983.

On a special AEW Dynamite episode, Cody Rhodes defeated Brodie Lee for the AEW TNT Championship. It was everything that most people thought it was, and so much more. It extended both men in more ways than one and served as a testament to Brodie Lee.

In a sense, Valentine's appearance on AEW Dynamite was in line with other legends that appeared on the show. Respectful and honoring those that came before. This has always been AEW's motto and, hopefully, it will continue to be so.
