Kotaro Suzuki
Kenta's first major rivalry in singles competition began in March 2005 following a dispute with SUWA, which led to a series of confrontations between the two, including a violent match that ended in his opponent getting disqualified for assaulting the referee. This led to Kenta getting one more chance to challenge for the Junior Heavyweight title against Yoshinobu Kanemaru at Destiny on July 18, which saw him win the title. He made his first defense two months later against Suwa, then against Kotaro Suzuki as his alter ego, Mushiking Terry. Simultaneously, Kenta began teaming with Katsuyori Shibata as The Takeover, challenging for the GHC Tag Team Championship, the heavyweight version of the company's tag team title.
