Built by Sei after the 7th Gunpla Battle World Championship, the Build Strike Cosmos is the culmination of all his Gunpla work up until then and is made to fit his battle style. Although visually identical to its predecessor, the GAT-X105B/ST Star Build Strike Gundam, the unique systems created by Sei were incorporated in a more refined manner. For example, the RG System was improved and a new feature known as the Absorb Field that seems to be an improvement of the Star Build Strike's Absorb System is added.

The Build Strike Gundam Cosmos was used by Sei Iori during the 8th Gunpla Battle World Championship Japanese Third Block Qualifiers. After the Build Strike Gundam Cosmos launched, its RG System was activated and its Absorb Field was deployed. The Gunpla then charges forward, leaving a colorful Plavsky Particle trail in its wake. It then remained as Sei's regular Gunpla for Gunpla battles.
