Perkins (Mummy on the Orient Express)

Perkins was the Chief Engineer on the space-faring Orient Express. He assisted the Twelfth Doctor in combating the Foretold, starting a timer whenever the Foretold attacked. After the threat was over, the Doctor subtly offered him a chance to travel with him, but Perkins declined. (TV: Mummy on the Orient Express)

Behind the scenes
Perkins' character was based on a real person of the same name, a friend of writer Jamie Mathieson, from whom he extracted information about the Orient Express. (DWM 478)
