Jinsei Shinzaki
On November 28, Gannosuke teamed with his ZEN teammate Yukihiro Kanemura and they defeated Hayabusa and Masato Tanaka to win the vacant Brass Knuckles Tag Team Championship and the two formed a very successful tag team, even surpassing their leader Atsushi Onita as the top villains of FMW due to them getting the biggest heel heat from the crowd. Friction arose within ZEN as Onita put himself in the main event of the December 19 show in the Super Extreme Wrestling War tour against Masato Tanaka, instead of Gannosuke and Kanemura's Brass Knuckles Tag Team Championship defense against Hayabusa and Jinsei Shinzaki, which the duo felt deserved to be the main event of the show and it led to a heated argument between Gannosuke and Onita. Gannosuke and Kanemura successfully defended the title against Hayabusa and Shinzaki. On the final day of the tour on December 22, the team of Onita, Gannosuke and Kanemura took on Hayabusa, Jinsei Shinzaki and Masato Tanaka in a WarGames match, during which Gannosuke and Kanemura showed tactics of dissension with Onita and turned on Onita after Onita was pinned by Hayabusa. They attacked Onita until Koji Nakagawa made the rescue and then Gannosuke, Kanemura and Hido left ZEN to form their own freelance group alongside Miss Mongol. This led Onita to turn fan favorite and Gannosuke cemented his place as the top villain of FMW.
