Technology & Combat Characteristics
The GN-000FA Full Armor 0 Gundam is the GN-000 0 Gundam equipped with add-on equipment that significantly improves the mobile suit's capabilities but at the cost of higher GN Particle consumption. It was developed by Sherilyn Hyde when the 0 Gundam was with Fereshte as a means of strengthening the Gundam in case it needs to be deployed.
The additional armors on the mobile suit's body are actually GN Composite Armor which was first used on GNY-004 Gundam Plutone. Besides improving 0 Gundam's defensive capability, the GN Particles within the GN Composite Armor also have the effect of reducing the equipment's weight. Additional weapons are mounted on the armor and includes a Beam Bazooka, a Twin Beam Gun, and a pair of Gundam Vulcans. The added armor can be cast off at any time and when it does, the large amounts of GN Particles within the GN Composite Armor will burst out and create a temporary defensive barrier that will protect 0 Gundam much like a GN Field.
The Full Armor equipment was considered for use with 0 Gundam (Type A.C.D.) during Celestial Being's final battle with the Innovators. However, since the 0 Gundam (Type A.C.D.) was powered by a particle storage tank instead of a GN Drive, the limited GN Particle supply was insufficient for the Full Armor equipment, so it was not deployed.
History
Originally, this equipment, alongside GN-000 0 Gundam, was meant to be used by Fereshte in their operations though it never was used. After the battle with the United Nations Forces, this equipment and 0 Gundam were given back to the Ptolemaios team. Before the final battle against the Innovators, this equipment was considered for deployment and a computer simulated battle was conducted, but it was eventually passed over due to the 0 Gundam lacking a GN Drive and thus unable to power it sufficiently.
