The MS-06Z Psycommu System Zaku is an experimental mobile suit from the design series Mobile Suit Variation.
One of the prototype machines developed by the Principality of Zeon under the "Bishop Plan", this mobile suit was also referred to by the name of this project. The Bishop Plan was part of Zeon forces' research into remote weaponry controlled by a Newtype's special brainwaves, with the plan's end goal being a machine with the model number of MS-16X and the name "Zeong". Since the One Year War was dominated by visual combat, it was hoped that if this plan was realized, it would introduce tactics comparable to the old style of electronic warfare. Equipped with a prototype of the psycommu system, the Psycommu System Zaku was one of three test machines prepared for collecting data and testing beam weapons at that time, with the other two being a medium-sized fighter, and the Braw Bro.
