Early in the 21 Century, the Tyrell Corporation advanced Robot evolution into the Nexus phase – a being virtually identical to a human – known as a Replicant. Replicants were used Off-world as slave labor. Those who escaped to Earth were hunted by Blade Runner units, ordered to kill any trespassing Replicant upon detection.
