No documented origin is given for this clip beyond its title and tags, which label it as an SCP-087 roar and name Notvxnvkvx. It is presented as a short, standalone soundboard clip rather than as an excerpt identified with a particular game, film, or recording. In that form it fits horror-themed edits and short videos, where a brief labelled roar can be reused without needing its original context. Its value online comes from that label and its brevity, letting creators reuse it whenever a sudden scare or tense reveal needs a quick sound.
