Bloody Mary

The Bloody Mary is a gigantic Mobile Weapon from the Plamo-Kyoshiro series.

Technological and Combat Characteristics
Despite it's name, the Bloody Mary is actually a modified Gundam with 4 arms, used to test the reliability of handling multiple weapons all at once. Because the arms can't hold all the weapons, the developers decided to increase the size of the mobile suit into a mobile armor, also equipped with several Ultracompact Minovsky Fusion Reactors to power the suit. Despite it's size, it's only equipped with light weaponry.

History
The unit first appeared in manga Plamo Kyo-shiro, the first non-UC Gundam, in other media. When the unit officially became part of the Universal Century Timeline, it retconned back with a UC mecha setting.

In it's UC setting, the Bloody Mary is supposed to be the official design of the MRX-009 Psyco Gundam. But due to the design, it is rejected. However, the multiple arm concept is been adapted to the development of the PMX-003 The O.
