Biography[]

Trevor was a bureaucrat sent to identify those citizens of Terra Alpha who had disappeared since his last census of six months previously. His work on the planet coincided with the Seventh Doctor's successful attempt to remove Helen A from power by starting a revolution. He later finished his study, and left to conduct a survey on Planet Earth, not too far away. (TV: The Happiness Patrol)
