Technology & Combat Characteristics
Shiro's customized Gunpla, the Perfect Gundam is a heavily modified 1/144 RX-78-2 Gundam equipped with heavy plastic armor and various equipment. Shiro's actual purpose for the equipment is to enhance the overall attack and defense capabilities of the RX-78-2. However despite the unit's enhancements, both speed and performance were not thought of and the said customization suffers from balance and performance issues.
The Perfect Gundam is a enhancement plan for the original RX-78-2 Gundam used to test a prototype version of the Full-Armor System and Weapon System (FSWS). The overall unit is planned to be reinforced with special removable armor and weaponry to maximize the overall performance and changing its overall appearance, but also gives the unit additional weight. The unit is also equipped with several thrusters on its legs and a high output backpack, which gave the unit excellent speed and mobility, however due to the high output, the unit sports a propellant tank on its back which allows the Perfect Gundam to have additional operational time.
The weaponry of the Perfect Gundam is also enhanced and changed, aside from retaining its vulcan guns and beam sabers. It is equipped with an enhanced 2-barrel Hand Beam Gun on it's right arm and a 360mm Rocket Gun on this back. It also sports a RX-M-SH-008/S-01025 type Shield, which also houses four Drop Mines.
History
The Perfect Gundam is first built by Shiro Kyoda during the first chapter of the manga. It is then modified and upgraded to the more balanced Perfect Gundam II.
The Perfect Gundam wasn't actually built and only exist as a CG Data for High Ranking Federation Officials. Very few knew about the unit's existence, especially on the history of its development as it was kept secret within the Federation's top members and researchers. However it's believed some of the specifications were carried onto the FA-78-1 Full Armor Gundam.
A gunpla of the Perfect Gundam was built and then piloted by Takeshi Iori, he used it to provide cover for his son Sei Iori, and Reiji, to destroy the out of control Plavsky Crystal. The only known modification to Takeshi's Gunpla is the conversion of the 360mm Rocket Cannon into a beam cannon.
Takeshi would use it again in London, England, where unauthorized Plavsky Particles were detected. Using a portable Gunpla Battle system, Takeshi uses his PF-78-1 Perfect Gundam to sneak into a building and open a door, allowing him and other members of the International Gunpla Battle Referees to bust in, unfortunately the room was empty; the people they were looking for weren't there.
