Bought this BB Gundam Sangokuden Brave Battle Warriors Ryubi Gundam limited set @ Kinokuniya not for the grey version Ryubi but for the Zhang Shi Ping (張世平) GM (Cold Districts Type) alternative head. I always wanted to custom build my own BB Sangokuden GM general rather than having them only as soldiers. This comic limited to SD Gundam Sangokuden to be released by "Gundam Ace" in year 2010, called "SD Gundam Sangokuden Brave Battle Warriors Volume Dawn Chapter Ryubi" which Zhang Shi Ping (張世平) GM (Cold Districts Type) was featured it. Beside the GM head, I had incorporated other parts which one obvious part is the cape from Ez-8 Gongsun Zan BB kit and others. I still maintain the grey overall to keep the GM faithful to cold districts colour scheme.
