The roar comes from Legendary Pictures' Godzilla, released in 2014 as a reboot of the classic Japanese monster franchise. For the film, Godzilla was presented as a massive ancient apex predator, and his distinctive roar became one of its most recognisable audio signatures. Short clips of different roar lengths circulated on soundboards and in fan edits, with medium versions becoming popular because they fit reveals and reactions without running too long. It remains in use today in memes, gaming videos and movie edits where a powerful monster sound is needed.
