Editing Replicant (section)

=== ''Blade Runner'' ===
Prior to the events of the film, replicants became illegal on Earth after a bloody off-world mutiny. Six replicants escaped the off-world colonies, killing 23 people and taking a shuttle to Earth; the film focuses on the pursuit of the replicants by Rick Deckard, a type of fictional [[police officer]] called a "Blade Runner", who investigates, tests, and executes replicants.

Escaped replicants (all Nexus-6 models):
* [[Roy Batty]] (played by [[Rutger Hauer]]), a self-sufficient combat model for the colonization defence program
* Pris Stratton (played by [[Daryl Hannah]]), a "basic [[Comfort women|pleasure model]]" for military personnel
* Zhora Salome (played by [[Joanna Cassidy]]), "trained for an off-world kick murder squad"
* Leon Kowalski (played by [[Brion James]]), a combat model or loader of nuclear fission materials
* An unnamed replicant—"Hodge" in early versions of the screenplay—killed in an electrical field at the Tyrell Corporation
* The sixth replicant was named "Mary" in early versions of the screenplay. The only mention of this replicant occurs in the 2007 "Final Cut" version — Captain Bryant's dialogue has been fixed to say that two replicants were killed by an electric field at the Tyrell Corporation; in previous versions of the film, he states it was only one replicant.

Other replicants:
* [[List of Blade Runner characters#Rachael|Rachael]], (played by [[Sean Young]]) is a prototype replicant, with implanted memories from Eldon Tyrell's niece. The sequel film further elaborates on this by revealing she was designed as a test run for a replicant that can become pregnant.

While Deckard discusses Rachael with Tyrell, Tyrell states that to better control replicants he started to implant false memories to give them the years of experiences that humans take for granted, creating a "cushion or pillow for their emotions."

Nexus-6 units were designed to have a four-year lifespan to avoid emotional development, and all attempts to increase a replicant's lifespan have resulted in death. According to Deckard, a normal replicant can usually be discovered using the Voight-Kampff test within 20–30 questions, though Rachael answers over one hundred questions before Deckard determines she is a replicant.

The second film further develops Rachael's origin, and gives significantly more details about her radical design. It revealed that she was an experimental model of replicant with a high percentage of human organs, including human reproductive organs, and that Rachael conceived a child with Deckard. As Rachael died during childbirth, her possible survival beyond the four years was undetermined.
