This clip appears to be a user-generated sci-fi sound effect rather than a line or excerpt from a known film, game or television show, and no specific original source is documented for it. That generic, title-driven origin is common on soundboards, where short effects are uploaded, labelled by their sound and reused across unrelated videos. Robot roars of this kind remain popular because they instantly convey artificial power and threat, making them a flexible shorthand for mechs, drones, AI characters and futuristic machines in gaming clips, memes and fan edits.
