Helen A

Helen A was the ruler of the human colony on Terra Alpha, enforcing her rule through the Happiness Patrol. She was overthrown by a revolt of the factory workers begun by the Seventh Doctor.

Biography
Helen A and her husband Joseph C were responsible for Terra Alpha, with Helen A building many factories where drones - forbidden from entering the city - worked. After being alerted to the overpopulation of the colony by Trevor Sigma of the Galactic Census Bureau, Helen A ignored the programme that she was given to solve the problem and instead began executing those that she deemed Killjoys, with the Happiness Patrol rooting them out and Gilbert M's Kandyman killing them.

Six local cycles after Trevor Sigma's visit, the population of the colony had been brought down by 17%, with more than 500,000 dead and the remaining population fearing her. However, the Seventh Doctor stirred up the factory workers to revolt. She sent her Stigorax Fifi to exterminate the pipe people and decided to flee because of the revolution taking place, finding that Joseph C and Gilbert M had escaped in her spaceship. The Doctor confronted Helen A and explained that happiness had to be juxtaposed with sadness to be meaningful and that love was important. She disagreed but broke down upon finding Fifi dead.
