A Super Neuromechanoid built with the cooperation of Akamatsu Heavy Industries. It combines StealthGao II (from Star GaoGaiGar) and LinerGao II and DrillGao II (from GaoFighGar) with the Neuromechanoid Awakener GaiGo. The most likely reason for the use of StealthGao II rather than III is that GaiGo cannot produce Program Rings, forcing GaoGaiGo to use the less powerful Phantom Rings. It is jointly piloted by Mamoru Amami and Ikumi Kaidou, and runs on a combination of Linker Gel and Ul-Tech power. The makers theorize that Ikumi Kaidou's J-Jewel energies will supercharge the G-Stones embedded in GaoGaiGo - this may be based on the effect seen with the jointly operated King J-Der. Other data concerning it is yet to be translated. Its model number is GBR-21.
