The RGM-79C Powered GM is a RGM-79C GM Type C that has been modified with advanced parts in order to test their functionality for use in future advanced mobile suits. Many of its new components are used in the form of a backpack system that incorporates a more powerful Minovsky-type ultracompact fusion reactor and more powerful thrusters. This new equipment granted the Powered GM significantly greater mobility. Its leaping height and speed greatly surpassed that of the MS-06F2 Zaku II F2 Type, and it has greater mobility when in midair. Because of the stress the mobile suit's legs receives when landing from such heights, heights greater than the GM Kai was originally intended to go, the Powered GM was outfitted with new shock absorbers in the knees.
