The file circulates on user-generated soundboards under the label Manticora, with embedded metadata describing it as manticore sounds from mythology and crediting EVOLVED GOJI (Mazellmi). Like many creature vocal packs, it appears to be an original designed effect rather than audio taken from a film or game. Fantasy creators, dungeon masters and horror editors have adopted it as a convenient shorthand for an unseen mythical predator, because few listeners have a fixed idea of what a manticore should sound like, leaving room for this growling interpretation to stick.
