In 2006, Puma wrestled as part of MTV's inaugural television taping for the Wrestling Society X (WSX) promotion, participating in a battle royal but being eliminated by Vampiro and competing in dark matches against Altar Boy Luke and Human Tornado. In a 2009 interview, Perkins stated he asked to be released from his contract with WSX, calling the promotion "terrible". Over the next two years, Perkins competed for several different National Wrestling Alliance promotions, and on June 1, 2008, at Mach One Wrestling's debut show, he won a battle royal to become the NWA Heritage Champion.
