Spoonhead
From Tardis Wiki, the free Doctor Who reference
Spoonheads were robots created to help the Great Intelligence. In their camouflage/outer-shell changing state they looked human except for the back of the head, but there is no known boundaries to what races or beings The Spponheads could disguise as. Their percieved appearence shifted in accordance with the subconciousness of the individual looking at them. Spoonheads would be controlled by the Great Intelligence's brainwashed workers to upload people to the Internet. (TV: The Bells of Saint John)
