Spoonhead
Spoonheads were robots created to help the Great Intelligence.
Appearance
In their camouflage state they looked human except for the back of the head, which resembled a spoon and could rotate. Their perceived appearance shifted in accordance with the subconsciousness of the individual looking at them. (TV: The Bells of Saint John)
History
Spoonheads would be controlled by people to upload others to the Internet for the Great Intelligence to feed on their minds. In 2013 London, a Spoonhead disguised as a character from the book, Summer Falls partially uploaded Clara, but the Eleventh Doctor stopped it.
When another Spoonhead, disguised as the Doctor, uploaded Clara successfully, the Doctor hacked into it, and the Spoonhead, still appearing as the Doctor, rode an anti-gravity motorbike up the Shard. The Spoonhead absorbed Miss Kizlet and used her tablet to raise Mahler's obedience when she asked her to download the entire cloud back to their bodies. (TV: The Bells of Saint John)
