When All-South Wrestling folded in 1974 both Hamilton and Renesto returned to Georgia Championship Wrestling, deciding to bury any past animosity. Renesto retired from the ring and focused more on the booking aspects of GCW while Hamilton started to work as a singles wrestler billed simply as "The Assassin". When he joined GCW Hamilton started a storyline with Mr. Wrestling II that would become the longest running storyline in Georgia wrestling history. Over the following years the Assassin would enlist several other "Assassins" to team with him as he fought against Mr. Wrestling II and various face partners. One of these partners was Randy Colley, who would go on to greater success as one of The Moondogs in the 1980s. Together Hamilton and Colley would hold the NWA Georgia Tag Team Championship on two occasions. Colley and Roger Smith would team together as the Assassins in Memphis.
