Sei’s new Gunpla, it is an upgraded version of the Build Strike Gundam Cosmos he used in the 8th World Tournament. Sei has worked on every inch of the Gunpla, it has new crystal parts on the chest, shoulders and legs, as well as thick armor that can withstand Vulcan shots. Even parts with no apparent changes have been improved. The most significant difference is the Galaxy Booster, a support unit that greatly improves the Galaxy Cosmo’s performance when docked and acting as the Gunpla’s backpack.

Additionally, the Gunpla’s RG System is further enhanced, and can be simultaneously activated with the Star System, which functions like a combined version of the Star Build Strike Gundam’s Absorb and Discharge System. Although the RG and Star systems can only be used together for a short period of time, they can raise the Galaxy Cosmo’s performance to its absolute limit. However, this also makes controlling the Gunpla harder.
