RGM-79 Powered GM

The RGM-79C Powered GM is an Earth Federation Mobile suit from the Universal Century, which first appeared in Mobile Suit Gundam 0083: Stardust Memory.

History
As the Earth Federation Forces rebuilt its military power in the years following the One Year War, it used existing GM units to serve as testbeds for developing technologies to be incorporated into new mobile suit designs. One such unit was the RGM-79C Powered GM, a heavily-modified RGM-79C Modified GM, built to test parts and systems for the Gundam Development Project. It mounted a heavy, powerful backpack that provided it with incredible thrust and acceleration, and was equipped with improved shock absorbers in the legs. Because the GM was built for efficiency and was never designed with this kind of equipment and performance in mind, the control systems for the backpack and other improvements were placed in external "boxes" on the Powered GM's armor, making it appear more heavily armored than it actually is.
