The GironGame continues the more heroic and friendly appearance of Gamera that had been established with the previous suit starting in Gamera vs. Gyaos. The suit is very similar to the modified BaruGame suit, featuring large benign eyes that are yellow in color. The suit is somewhat lighter in color than the previous suits as well. The backside of the shell still features spike-like structures, however they now sit flat on the shell and no longer protrude outwards.
