The MS-06R-3S High Mobility Type Zaku was a high performance MS created using one of the four MS-06R-2 Zaku II High Mobility Types and has mobility that can compete with the Federation's RX-78-2 Gundam. It was developed in a short period of time by using large number of parts from the Gelgoog. Significant increase in its generator output granted it sufficient power to use the Zeon forces' first beam rifle and beam saber, which are in prototype stage. However, this machine was equipped with a heat sword instead of a beam saber. It is considered the missing link between the Zaku and the Gelgoog, and is also known as the Gelgoog Early Prototype.
