Rumble fighter is it just us and the koreans?

Minbat was a Chinese Version of RF. Those are test server pictures, However it wasnt called gemfighter or rumble fighter. It was really Minbat

 

MinBat was the original Japanese one I thought? Mina no Batouru, "people's tournament". I remember reading about it early in GC's time but I never experienced or saw anything other then their Martial Arts Soul being black and purple like our BFE is now.

 

Oh maybe Japanese not chinse. Nimonix just talked about it as "Minbat"

However you're totaly right about the Black Martial Art Soul. I forgot about it. As well as cosmetic changes on certain maps
