Smiler

The Security Monitoring Integrated Liability Enabler or Smilers were a type of android used aboard Starship UK.

History
The Smilers were mounted in booths around the Starship UK. When a citizen broke the law or was deemed unnecessary, the Smilers would feed them to the star whale; children who were sentenced to work in the Tower of London. The Smilers rotated their heads to show three faces: happy, displeased (for warnings), and angry (when attacking). While they had three faces, they appeared to rotate their heads halfway around, which should mean they only had two. This might mean that faces could be removed when they rotated.

While Smilers appeared to be merely heads, in extreme circumstances they would leave their booths and attack. The terrified population kept the areas around their booths clean and never dared get too close to them. The Smilers could quickly repair themselves from damage such as being shot.

Humans hybridised with Smilers were known as Winders and formed a secret police force that maintained the clockwork machinery on Starship UK. (DW: The Beast Below)
