Technology & Combat Characteristics
In preparation for the looming decisive battles against the UN Forces, the Celestial Being deployed the enhancement and support machine – the GN Arms, of which the GN GN Arms Type E is for GN-001 Gundam Exia and the GN Arms Type-D is for Dynames. Each GN Arms can dock with their Gundam partner to form the GN Armor, with the GN Armor Type-D being the combination of GN Arms Type-D with Dynames. As per the name, the GN Armor provides the Dynames with enhanced mobility, offensive and defensive capabilities, revealing the ultimate power of the Gundam.
With the GN Armor Type-D, the Dynames' long-range shooting capabilities are boosted by the GN Arms Type-D's GN Twin Rifle and the Large-Size Missile Container, both meant for anti-fleet combat, and the support machine's Large-Size GN Cannons and Claws are also available for ranged bombardments and close combat respectively. Furthermore, the GN Armor Type-D can deploy a GN Field for better defensive capabilities, and the machine's performance can be enhanced for a brief period of time when the docked Dynames activates Trans-Am System. As the Dynames' arms are free to move while in GN Armor Type-D, it is possible for the Gundam to use its own weaponry. The GN Arms Type-D also benefited from the combination as it gains access to the Dynames' GN Drive via the Gundam's cone thruster, allowing its capabilities to be utilized at their full potential.
To form the GN Armor Type-D, the GN Arms Type-D has to undergo a quick and simple transformation where it expands and opens up for docking with Dynames. During the transformation, the GN Arms Type-D's top sections tilt backwards, the center block containing its cockpit flips to the rear and exposes the connector for the Dynames' cone thruster, the two folded leg-like parts at the bottom containing the mount latches for the Dynames' feet expand and rotate downward, the two arm-like units containing the GN Twin Rifle and Large-Size Missile Container position further to the sides, and the wings are folded up against the main body. The Dynames simply attaches to the three aforementioned docking points to form the GN Armor Type-D, and can easily eject from the machine when needed to fight on its own.
When a pilot is present in the GN Arms Type-D, control of the GN Armor Type-D is shared between the support machine's pilot and Dynames' pilot. The whole GN Armor Type-D can also be controlled from the Dynames, with the Haro in the Gundam's cockpit providing support and helping to operate the GN Arms Type-D component.
History
During the UN Forces' second attack on the CBS-70 Ptolemaios, Lockon and his GN Armor Type-D launched mid-way through the battle and took out a number of the enemy's GNX-603T GN-Xs with a barrage of GN Missiles. The GN Armor Type-D then sped off to assault the UN Forces' Virginia-class carriers, sinking two with its beam weaponry. However, before the last carrier could be sunk, the GN Twin Rifle was destroyed by Ali al-Saachez's GNW-002 Gundam Throne Zwei. Subsequently, the GN Arms Type-D component was heavily damaged by the enemies' attacks, forcing Lockon to eject the Dynames to continue the fight. The Dynames was later incapacitated, and Lockon left the Gundam with the rifle-shaped controller in hand. He then found one of the wrecked GN Arms Type-D's Large-Size GN Cannons, connected the rifle-shaped controller to it, and shot down the Throne Zwei using the cannon. As the Throne Zwei exploded, it fired a beam shot in retaliation, destroying the Large-Size GN Cannon and killing Lockon.
