Called 'Gyaosu' in Japan, Gaos is the greatest enemy of Gamera in the Daiei kaiju films. The several-hundred foot tall flying giant monster, a cross between a vampire bat and a foxbat, has no radar sense but can screech a supersonic beam that can slice through almost anything. Additionally, he can topple buildings with only the shockwaves from flying overhead. Unlike Rodan, Gaos never stops hating and preying on humanity.
