Wow, never heard of this before, that match between Genki and Uno was unbelievable though! Not surprised he didn't tap to that triangle, Caol never dies...
Was GCM a Japanese organization?
GCM stood for Greatest Common Multiple and was a sort of parent company that ran these organizations. i believe it also ran the Wajyutsu Keisyukai gyms for a while, and Caol Uno was heavily involved in their events although i'm not really sure in what capacity.
GCM's first real organization was DEMOLITION, which was a normal ring-based organization. then they started holding events under an organization called D.O.G. (Demolition of Octagon Gear), which was the first japanese organization to use a cage. that would evolve into Cage Force, which held several tournaments, the winners having real opportunities to go fight in the US. Takeya Mizugaki and Yoshiyuki Yoshida came to the WEC and UFC respectively after winning their tournaments in Cage Force.
they also had a women's organization called Valkyrie which was competing against Jewels as organizations that sprung up after Smackgirl folded, with Valkyrie getting fighters like Yuka Tsuji, V.V Mei, and Rin Nakai.
but they ran into financial trouble, they stopped holding events and eventually their organizations folded, and fighters took control of some of the Wajyutsu Keisyukai gyms from GCM.
already posted videos of Contenders matches, but for GCM's MMA organizations...
