Kandyman

The Kandy Man was a robot created by Gilbert M and employed by Helen A.

The Kandy Man (or Kandyman) was a pathological, psychopathic robotic killer who was employed by the egocentric Helen A. The Kandy Man delighted in creating methods of torture and destruction using confectionery, such as drowning people in sugary solutions like its "fondant surprise". It was sadistic, speaking with a squeaky voice and had a very warped sense of humour, claiming it liked its victims to "die with a smile on their faces" by making candies that were so sweet the human body was unable to cope with the pleasure.

Composed of things like sherbet, marzipan and caramel, it was created by Gilbert M, with whom it shared an almost symbiotic relationship. The Doctor stuck the Kandy Man to the floor using lemonade — it had to keep moving or its constituent ingredients would coagulate. The Kandy Man died when its external candy shell was dissolved in a pipe by fondant surprise released by the oppressed Pipe People. (DW: The Happiness Patrol)

The Doctor encountered the Kandy Man again on the planet Tara. Count Grendel rebuilt the Kandy Man after its charred body crash landed on Tara. (VD: The Trials of Tara)
