History
The Smilers were mechanical androids that were used as "guards" on Starship UK. They were placed in booths and if at any time a citizen of Starship UK decide to press the protest button, they would switch to their demonic face and come out and attack the protesters. They had three personalities:
Smiling - This was the face that they would be seen in usually and in the market place of Starship UK. At this point they seemed harmless to innocent tourists such as Amy and the Doctor, but they still had a hidden agenda...
Frowning - The Smilers usually took this form if a citizen entered a disclosed area, or if a child recieved a "zero".
Demonic - The most scary form of the Smilers. The eyes would become red and the mouth would have a deformed grin. It would take this form when attacking protesters or sending a child to the lower levels.
Notes
They resemble arcade fortune tellers. At some points, smiler faces were attached to the back of human heads of members of the starship UK inquisition.
