Bellboy
From Tardis Wiki, the free Doctor Who reference
Bellboy built and repaired the robot clowns at the Psychic Circus on Segonax. He ran away with Flowerchild from the circus, but Flowerchild was killed by the bus conductor robot.
He was forcibly brought back to the circus by the chief clown and the robot clowns, and when he realised that he was unable to run away again he programmed the robots to kill him. (TV: The Greatest Show in the Galaxy)
