The Star Build Strike Gundam is an upgraded version of the GAT-X105B/FP Build Strike Gundam Full Package. Sei Iori designed this Gunpla to shock participants all over the world in the Gunpla World Tournament. It retains all of the original weaponry from the Full Package, with some of them being redesigned and new features added. It also sports a new backpack—the Universe Booster—armed with two beam cannons and can act as an independent fighter when separated. As Sei utilized the knowledge he gained from building the RX-178B Build Gundam Mk-II when constructing the Star Build Strike, the Gunpla ends up having an inner frame similar to the former's movable frame.

The Star Build Strike also has three unique Plavsky Particles-manipulating systems: the Absorb System, the Discharge System and the Radial General Purpose (RG) System. They are the final product of Sei thinking outside of the Gundam-lore. The Absorb System allows Star Build Strike to absorb enemy beam attacks through its shield. The Discharge System's main purpose is to create a "Plavsky Power Gate" that then allows the use of the absorbed particles to enhance the Gunpla's performance in a specific area.
