Godzilla Raids Again
Within "Godzilla Raids Again", Anguirus' last roars, before being killed by Godzilla, caused ultrasonic-like effect which produced cracks on Osaka Castle. Anguirus was also noted to be able to emit stunning poison from his claws and back spikes. Anguirus was also originally planned to breath an atomic ray in "Godzilla Raids Again", and this was recorded in the official novelization of the film.
