Result of Final Fusion with StealthGao II in place of the original StealthGao. StealthGao II incorporates an optional "Space Booster" that allows GaoGaiGar to remain in space for much longer operational periods. This apparatus consists of a nacelle attached to the end of either wing edge and a bladed wing assembly attached to its upper surface. (The Space Booster can also be used in atmosphere, though any potential drawbacks of doing this are unknown.)
