gogg
A fictional mecha from the Gundam series. It first appeared in Mobile Suit Gundam from 1979.
MSM-03 Gogg
The first truly amphibious MS developed by Zeon, intended to replace the poorly suited (and never mass produced) experimental Zaku Mariner. Unfortunately, it relied too much on the water to cool its massive reactors, and was extremely impractical in combat.
Its basic design was a breakthrough, however, and it went on to inspire not only a successor unit, the Hygogg, but also other great amphibious MSs such as the Acguy family and the successful Z'Gok.
In real life the basic design of the Gogg was inspired by the Boss Borot from the Mazinger Z super robot series.
