"Eyeball" was the name Steven gave to a homeworld Ruby. Eyeball was sent to Earth along with other Rubies to discover the whereabouts of Jasper (whom Eyeball idolized and sympathized with, as she shared Jasper's hate for Rose Quartz). But Eyeball and her platoon were outsmarted by the Crystal Gems in both encounters, and she was last seen drifting in deep space.
