Outlier droid

A robot girl controlled two non-human entities disguised as orderlies, kidnapping patients from Rory Williams' hospital, at the climax of the Slow Invasion. She held an active Shakri cube and the sclera of her eyes glowed blue. She was discovered by the Eleventh Doctor who revealed her to be a simple gynoid overseeing the entire operation. The Doctor shut her down. (TV: The Power of Three)
