土井成樹
He turned up in Dragon Gate on March 19, 2006, being brought in by Magnitude Kishiwada (previously known as Big Boss MA-G-MA) to take over his position in Blood Generation while he recuperated from a severe shoulder injury. He and stable head CIMA took an instant dislike to each other, however, and he was soon kicked out of the faction. Naruki Doi, Masato Yoshino, and Naoki Tanisaki followed him, causing Blood Generation to split in two, with them on one side and CIMA, Don Fujii and Shingo Takagi on the other. On April 23, 2006, he and Doi beat CIMA and Fujii in a tag match to earn full rights to the Blood Generation name, but they immediately renounced it, instead forming the Muscle Outlaw'z faction. Though Naruki Doi was seen as the leader, Gamma was considered a co-leader or even the real leader. The split also marked the beginning of a long feud he would have with CIMA.
