The clip is credited to Taira Komori, a Japanese creator known for free sound effects that circulate widely in games, videos and soundboards. This roar is tagged for SCP, the collaborative horror universe built around contained monsters and anomalies, which explains its use in fan games and edits. As soundboards spread the effect, creators began using it outside SCP as a generic creature roar, often grouped with sounds like the FNAF Jumpscare Scream for horror montages. Its length and build make it a staple for reveals rather than quick stingers.
