This roar comes from Godzilla, the 2014 film directed by Gareth Edwards that relaunched the character for Legendary Pictures and Warner Bros., giving the monster a new, deeper vocalisation distinct from the classic Toho roar. The sound quickly became associated with that version of Godzilla in trailers, games, fan edits and reaction videos, where its size and menace made it an easy shorthand for a huge threat arriving. It remains popular because it is instantly recognisable, dramatic without dialogue, and works for both serious monster edits and exaggerated meme moments.
