The YRMS-106+BL-85X By-Zack TR-2 [Big-Wig] was created for functional testing of a mobile suit-portable long-range beam cannon, and the thrusters and operating systems needed to transport and operate it. For various reasons, the YRMS-106 Hi-Zack Early Type was chosen as its base machine. The Hi-Zack was designed to be more modular than the GM series which previously served as the Earth Federation Forces’ main mobile suit, making it simpler to replace its parts. Thanks to its advanced modular construction this machine was unusually easy to modify, and by reconnecting the exposed power pipes on its exterior, its energy could be output to external mechanisms. This made it particularly suitable for use with the Big-Wig design concept. The Big-Wig was equipped with a second Hi-Zack generator to help power its beam cannon. It had two shields with built-in attitude control verniers, one of which served as a guard when the beam cannon was deployed. The “thruster units” on its legs were independent modules, each containing a thermonuclear reactor, thrusters, propellant tanks, stabilizing claws and landing gear. The generator devices visible within the intakes of these thruster units were similar to those used in the booster pods of the RX-121 Gundam TR-1 [Hazel] and RMS-117 Galbaldy β with High Mobility Unit.
