The GAT-X105B/GC Build Strike Galaxy Cosmos was an upgraded version of Sei Iori’s GAT-X105B/CM Build Strike Gundam Cosmos. The Galaxy Cosmos was a further development of concepts that Sei created in earlier versions of the Gunpla, including the Radial General (RG) Purpose System, which could power up parts of the kit by concentrating Plavsky particles. The new Star System could create a power gate that boosted the unit’s offensive power. When both the RG and Star Systems were activated, the Galaxy Booster could deploy its 12 wing pieces, which allowed Sei to control Plavsky particles over a wide range. Sei debuted the upgraded Galaxy Cosmos in a friendly match against Meijin Kawaguchi’s amazon.co.jp A-Z Gundam. A fierce battle ensued, but a stroke of luck in Sei’s favor caused the match to end in a draw.
