Autons are the living plastic foot-soldiers of a formless entity known as the Nestene Consciousness. Its affinity for and ability to animate plastics has led it to Earth many times, and into conflict with the Doctor. From replacing shop-window dummies and people in positions of authority with Auton replicas to deadly plastic chairs, dolls,daffodils and rubbish bins, the Nestene have attacked humanity in some of the most creative and grisly ways imaginable. The Ninth Doctor claimed to have witnessed the destruction of the Nestene homeworld in the Time War, but was unable to save it. As part of the Pandorica Alliance, the Nestene created Auton Romans at Stonehenge – including Rory Williams – from Amy Pond’s memories.
