Called 'Radon' in Japan, Rodan is one of the big four Toho Studios kaiju. The several-hundred foot tall flying giant monster, a cross between a pteranodon and an archaeopteryx, can topple buildings with only the shockwaves from flying overhead. In the original movie, there were two Rodans, and when one died in a volcano the other suicided in mourning for its mate. Since then, a single Rodan has often teamed up with Godzilla, King of the Monsters, usually as air support.
