The definitive command unit based on the reliable if unimpressive Zaku IImobile suit. While being visually almost completely indistinguishable from a standard model, notably only by its Commander Radio Antenna and extra thrusters on the feet area, its greatly superior performance was usually what tipped off its enemies - shortly followed by their imminent demise.
Despite being very common among Zeon's ranks, the most famous unit was definitely the red Zaku II piloted by Char Aznable, "the Red Comet", whose piloting skills and prowess created the myth that his suit was capable of moving at three times the speed of a regular Zaku.
