This sound is best known as a general fantasy creature effect rather than a quote tied to one specific character or franchise. Dragon roar audio like this is widely used in game clips, tabletop content, cinematic edits and meme videos whenever creators want a huge mythical beast presence. Its long duration makes it useful for reveals, attacks and scene transitions, not just quick reaction cuts. It stays popular because the sound instantly communicates danger, size and classic fantasy energy with almost no setup.
