Spare Parts (audio story)

 was the thirty-fourth monthly Doctor Who audio story produced by Big Finish Productions. It explained the somewhat surprising origins of the Mondasian Cybermen.

It was the partial inspiration for two 2006 Doctor Who television episodes — The Age of Steel and Rise of the Cybermen, on which Spare Parts writer Marc Platt received acknowledgement.

Publisher's summary
"I'm not even sure they are people by the end. They’re just so many tinned left-overs..."

On a dark frozen planet where no planet should be, in a doomed city with a sky of stone, the last denizens of Earth's long-lost twin will pay any price to survive, even if the laser scalpels cost them their love and hate and humanity.

And in the Mat-infested streets, round about tea-time, the Fifth Doctor and Nyssa unearth a black market in secondhand body parts and run the gauntlet of augmented police and their augmented horses.

And just between the tramstop and the picturehouse, the Doctor's worst suspicions are finally confirmed: the Cybermen have only just begun, and the Doctor will be, just as he always has been, their saviour...
