Takuya Sugawara
After leaving OPW, Gamma started appearing as a freelancer in Michinoku Pro Wrestling and Pro Wrestling Zero1, again as a villainous character. His activity in M-Pro was mainly outside of the rings, but he managed to corrupt the Sato brothers into turning heel, attacking The Great Sasuke and helping him form the group STONED. At the same time, he exerted his influence over his tag team partner in Zero1, Takuya Sugawara, turning him into an honorary STONED member. Gamma also appeared in Dragondoor, teaming up with yet another STONED recruit, Kagetora, who he appointed as the stable's next leader after Gamma signed up with Dragon Gate.
