In the Lab Rat comic, the Companion Cube can ACTUALLY talk to you! I would talk to him all day, or make him robotic arms so we can play co-op games together!! :D Other than that, I'd use him as a shield since Aperture cubes are highly resistant against any type of bullets or some ballistic missles. :3
