Technology & Combat Characteristics
After the Gundam AGE-1 Flat was severely damaged, it was eventually upgraded to keep its performance on par with current mobile suits. Its upgrades consisted of additional armor and new weaponry in the form of a pair of forearm-mounted Shield Rifles as well as six Missile Launchers in the added armor pieces. With enhanced defensive and offensive capabilities, this new form is known as Gundam AGE-1 Glansa. The AGE-1 Glansa was later equipped with the new Glastron Launcher, a back-mounted high mobility unit armed with a pair of beam launchers, and become known as the Gundam AGE-1 Full Glansa. When needed, both the additional armor and the Glastron Launchers could be purged.
History
Following its battle against Zeheart Galette's Xvt-zgc Ghirarga and Zanald Beihart's Xvm-zbc Xamdrag, the badly damaged AGE-1F Gundam AGE-1 Flat was upgraded into the AGE-1G Gundam AGE-1 Glansa to keep up with the more modern mobile suits. The AGE-1 Glansa first saw action at Luna Base, where it assisted Kio Asuno's AGE-FX Gundam AGE-FX and Asemu Asuno's AGE-2DH Gundam AGE-2 Dark Hound against Fram Nara's Xvb-fnc Fawn Farsia, Zeheart's Ghirarga, and Girard Spriggan's XMS-005 Thieleva. The AGE-1 Glansa fought evenly against the enemy units, but Girard lost control of her X-Rounder abilities and briefly stunned the Gundam before attacking it with the AGE-FX's C-Funnels. Ultimately, the AGE-1 Glansa defeated the Thieleva by shooting through its chest from above. Following this, Flit attempted to chase after the retreating Vagan forces using the AGE-1 Glansa, but was stopped by Kio, who pleaded for his grandfather to let the battle end.
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.
