Mr. Gannosuke
In September 1996, Lethal Weapon disbanded and Oya joined Funk Masters of Wrestling, where he formed a trio with The Headhunters and won the FMW World Street Fight 6-Man Tag Team Championship. After the Funk Masters disbanded, Oya decided to turn face for the first time in his career and join forces with Hayabusa. Up until the demise of FMW in February 2002, he fought alongside Hayabusa in his wars against Mr. Gannosuke and Kodo Fuyuki.
