Gangers
Gangers (short form of Doppelgängers) were a clone race created by humans from an artificially created organic substance called the Flesh.
Biology
Gangers were duplicates of individuals who controlled them through telepathic remote control. This allowed humans to work in extremely hostile environments without risk to themselves.
Gangers were mostly unstable and would often shift between half-Flesh and full human faces. In one case, a Ganger has been able to extend their limbs and neck due to the instability of the Flesh material.
