Bandai announces that there's going to be a limited set of SD Gundam Sangokuden Brave Battle Warriors Ryubi Gundam and Zhang Shi Ping (張世平) GM (Cold Districts Type) to be released.
Part swapping between the two characters.

In the story, Zhang Shi Ping is a wealthy businessman in Yuushuu (幽州) who donated horses to Ryubi Gundam for his battle against some bandits.
Rich GM, richer than Gundam. ^^
