Technology & Combat Characteristics
The Gundam Astray Blue Frame Second G is another configuration of Gundam Astray Blue Frame Second. The "G" in the designation stands for "Gai" and is added to differentiate it from Gundam Astray Blue Frame Second L. Blue Frame Second G is the original upgraded form of MBF-P03 Gundam Astray Blue Frame that Gai had in mind. It features redesigned shoulders and feet designed by Gai himself, while the rest of the MS is unchanged from that of the original Blue Frame.
The new, smaller feet give the MS better jumping power and are mounted with retractable "Armor Schneider" combat knives in the heels and toes, which could be used as kicking weapons or as anchoring spikes. The new shoulders contain fin thrusters to improve the suit's evasion capability, and can also be used to make unexpected sideways maneuvers during battle. Two other combat knives are also equipped on the hips. As Gai wants Second G to be a fast and mobile MS, he discards the physcial shield; he plans to rely on the MS's speed to dodge beam attacks and the antibeam-coated combat knives or the back-mounted beam sabers to battle against other melee beam weapons.
Unfortunately, all the new parts were not completed in time for Gai's battle against the Socius clones and are added to Blue Frame during the repair. Although the Blue Frame was reborn as Gundam Astray Blue Frame Second L after its repair, it can still become Second G by changing its head and backpack. As a result, the Second G now also has Trans-Phase armor around the cockpit. Blue Frame Second G retains the ability to use Blue Frame's complete sensor unit and this also shows that some of the equipment developed for Blue Frame can be used on the Blue Frame Second.
The suit's battery was later replaced by Morgenroete Inc. with one that has higher performance, this improved the suit's operating time by 30%. A sniper pack is eventually developed for Blue Frame Second G, giving it enhanced long range attack capability. By switching the shoulders and feet with those of the original Blue Frame's, Blue Frame Second G can transform into a form almost identical to the original Blue Frame.
History
The Astray Blue Frame Second G was the original upgraded form of MBF-P03 Gundam Astray Blue Frame that Gai had in mind. However, the upgrade parts were not ready before Gai's battle with Eleven and Seven Socius. They were fitted onto Blue Frame at the same time as repairs were made to the damaged MS.
In mid C.E. 71, Gai used the sniper pack equipped Blue Frame Second G during his first encounter with Canard's Hyperion Gundam. The complete sensor unit equipped Second G was used during the battle against ZGMF-X11A Regenerate Gundam to locate Regenerate's spare modular parts. Gai later switched back to Second L to confront Regenerate together with MBF-P02 Astray Red Frame "Powered Red".
