The male MUTO is one of the two giant monsters introduced in Gareth Edwards' Godzilla from 2014, a winged creature that hunts for radiation and eventually faces Godzilla in San Francisco. Its roars were designed to sound distinct from Godzilla's own call, more shrill and animalistic, helping audiences tell the creatures apart in dark, chaotic battle scenes. Clips of its different roars later circulated on soundboards and in fan edits, where editors reuse them as a ready-made kaiju scream without needing to lift audio from the film itself.
