Godzilla first appeared in Toho's 1954 Japanese film Gojira, and the monster's distinctive roar quickly became inseparable from the character across decades of sequels, animated series and Hollywood remakes. As the franchise grew into one of cinema's longest-running monster series, the sound travelled far beyond the films, becoming shorthand online for anything huge, unstoppable or dramatically overblown. Creators still reach for it because audiences recognise it instantly, even without seeing Godzilla on screen, giving any clip instant monster-movie scale.
