真壁刀義
After losing the IWGP Heavyweight Championship to Hiroshi Tanahashi at Wrestle Kingdom V in Tokyo Dome, Kojima suffered another big loss against longtime rival Togi Makabe on May 3 at Wrestling Dontaku 2011. Following the match, Michinoku and Taichi entered the ring and attacked Kojima, who, however, quickly took care of both of them. This led to the surprise return of freelancer Minoru Suzuki, who appeared behind Kojima and locked him in a sleeper hold, before leaving the ringside area with Michinoku and Taichi, who proclaimed Suzuki as their new leader and renamed the stable "Suzuki-gun". On May 15, during the Invasion Tour 2011, NJPW's first tour of the United States, Lance Archer made his debut for the promotion, attacking Kojima after a match, before being chased away by former Kojima-gun member MVP. The following day, Archer was officially named a member of Suzuki-gun. During the following months, Suzuki continued his feud with Kojima, while Archer went up against Togi Makabe and Michinoku and Taichi became a tag team in NJPW's junior heavyweight tag team division. Suzuki's feud with Kojima culminated on July 18 in a grudge match, where Suzuki was victorious, after which he transitioned to feuding with Togi Makabe.
