Ganger

The Gangers- their name a shortened form of the term 'doppelgängers'- were a clone race created by humans from the Flesh, typically controlled by their templates via specially-designed harnesses. This allowed humans to work in hostile environments without risk to themselves, as the Gangers could be easily recreated and any damage they sustained would not be felt by the real human as the nerve endings automatically shut down.

History
The Ganger process was developed some time during the 22nd century, and was in use at many facilities. An incident at the Isle of Surrey, in which a Ganger was electrocuted, resulted in the Ganger gaining sentience and horrifically killing its operator.

When a solar storm struck a factory using Gangers, the five active Gangers gained independent thought and motion, being implanted with the memories of their templates and becoming increasingly fixated on the possibility of making their own lives. (DW: The Rebel Flesh)
