The clip comes from a user-generated soundboard rather than a named film, game or viral video, so its exact original recording is not documented. That is common for short gore effects, which are often assembled from stock slashes, splats and impact sounds and then shared for reuse in edits. In Portuguese, its title simply describes the action, a claw attack with blood, which helps editors find it when they need a violent hit. It remains useful because the sound is short, clear and instantly readable, even without any visual context or dialogue.
