The PF-78-1 Perfect Gundam is a variation of the RX-78-2 Gundam, the titular mobile suit of Mobile Suit Gundam, and the first non-UC Gundam. Designed by Kunio Okawara and later by Hajime Katoki for the Gundam Fix Figuration version, it played a prominent part in the manga Plamo-Kyoshiro, and later became part of the original design series Mobile Suit Variations (MSV). Its built and piloted by Shiro Kyoda.
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 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.
