This is an original Federation Mobile Suit I designed for a Mekton role-playing campaign I played in. It's the Earth Federation Space Forces' standard Mobile Suit in U.C.0401 -- a highly advanced derivative of the GM with Minovski Drives, Psychoframe, I-Field Barrier, the works. It's name, "GzS," is pronounced "Jesus" and it stands for Gundam-type Zeta-derived Superior (or something like that).
This image shows the fully decked-out version of the MS, used for high-intensity circumstances. It integrates a variety of variants' equipment: a Hi-Mega Cannon on the forehead, dual Hyper Beam Launchers on the shoulders, a G-BRD rifle, and Micro Missile pods on the legs.
