The MSN-02 Perfect Zeong is a prototype Newtype-use mobile suit, and the completed version of the MSN-02 Zeong. It first appeared in Plamo-Kyoshiro, and later in the original design series Mobile Suit Variations (MSV) and the Mobile Suit Gundam: Char's Deleted Affair: Portrait Of Young Comet manga.
Prior to its appearance in Plamo-Kyoshiro, this version of the Zeong was referred to as the Zeong (Completed Unit). The name Perfect Zeong was given by Sacky Takeda, claiming that if Shiro Kyoda's custom Gunpla is the Perfect Gundam then his is the Perfect Zeong.
The Perfect Zeong was the final unit produced under Zeon's MS-16X Bishop Plan. Using the data obtained from the test runs of the MSN-01 Psycomu Test High Mobility Type Zaku II, Zeon engineers drafted plans for a new mobile suit and constructed the Perfect Zeong. Due to the MSN-02's massive size and the vast amount of energy required to power its multitude of beam weaponry, the Perfect Zeong's fusion reactor is 3.8 times larger than that of a standard mobile suit.
