During the final assault on La Gramis, the AGE-1 Glansa was equipped with the Glastron Launcher, becoming the Gundam AGE-1 Full Glansa. It fought at the front as the Federation troops began making their way to the fortress, but fell into a trap as the fleet was struck by La Gramis' Digmazenon Cannon. Realizing that the cannon was charging up faster than expected due to its link with the Vagan colony of Second Moon, Flit ordered all troops to abandon their ships so as to escape the line of fire. Flit and Kio also escaped La Gramis' second attack thanks to the Dark Hound's Hyper Boost. Near the end of the battle, the three Gundams were confronted by Zera Gins' Xvg-xxx Vagan Gear. After a brief clash, the Vagan Gear was overtaken and merged with the sentient mobile suit Sid before rampaging across the battlefield, regardless of friend or foe. Although confused, Flit nonetheless saw an opportunity to finish the Vagans and reverted his Gundam to AGE-1 Flat, and then equipped it with the Plasma Diver Missile to destroy both Second Moon and La Gramis.
