Hajime Ohara
After Tajiri worked for Fight Club Finland, he asked StarBuck to be part of his new Smash promotion. On May 29, 2010, at "Smash.3", he appeared in a video to start an invasion storyline involving wrestlers from FCF. The storyline led to StarBuck becoming an instant main-eventer in Smash. After several more videos and a match, where FCF wrestler Valentine lost the Finnish Heavyweight Championship to Tajiri, StarBuck announced that he was going come to Japan in person to reclaim his promotion's title. StarBuck made his Smash wrestling debut on July 24 at "Smash.5", squashing Hajime Ohara, winning the match by pinning him with one finger after a spike piledriver. Later that same day on "Smash.6", StarBuck defeated Tajiri in the main event to regain the Finnish Heavyweight Championship, his fourth time winning the title. After the match, Hajime Ohara turned on Tajiri and joined StarBuck's group of FCF wrestlers. After successfully defending the title against Akira on September 24 at "Smash.8", StarBuck lost the Finnish Heavyweight Championship back to Tajiri on November 22 at "Smash.10", after which he was attacked by the debuting Austrian wrestler Michael Kovac, who announced his intention of taking over Smash. On January 29, 2011, at "Smash.12", Kovac defeated StarBuck in a grudge match and used the momentum to capture the Finnish Heavyweight Championship from Tajiri later that same day on "Smash.13". Meanwhile, StarBuck went on a win streak, scoring pinfall victories over Super Crazy, Tajiri on two more occasions, Takao Omori, Yoshiaki Yago, Leatherface and Shinya Ishikawa.
