The MSM-07 Z'Gok (ズゴック Zugokku?) is a mass-production amphibious mobile suit introduced in the anime Mobile Suit Gundam.
The MSM-07 Z'Gok is one of the heavy mobile suit developed by MIP. Like the MSM-04 Acguy, it is viewed as a second-stage amphibious MS, different from the MSM-03 Gogg, a first-stage unit. The Z'Gok's final design was improved based on actual combat data from the Gogg, but this delayed its development and the Acguy was completed before it.
Among amphibious mobile suit, the Z'Gok's focus is on ground combat. Besides using both air and water-cooled radiators, it also has chemical fuel rockets for jumping in addition to thermonuclear water jets. The Z'Gok is also designed so that it can perform anti-air combat as well as search operations on and above the water surface, duties that the Gogg could not.
The Z'Gok's specifications are superior to those of the mass production mobile suits by the Earth Federation Forces at the same period. However, in return for high performance, it is difficult to pilot. Furthermore, it is a costly machine because it lacks parts compatibility with the Gogg.
