In Blade Runner, the replicant leader who seeks more life from his creator is Roy Batty.
Roy Batty is a Nexus-6 replicant portrayed by Rutger Hauer. He leads a group of escaped replicants who return to Earth from an off-world colony, hoping to find a way to extend their artificially limited lifespans. Their search brings Roy to Eldon Tyrell, the founder of the company that created him.
Roy is not a conventional robot: Blade Runner presents replicants as bioengineered synthetic humans rather than metal machines. That distinction is a frequent source of confusion when the film is grouped with robot movies.
The 1982 film was directed by Ridley Scott and adapted from Philip K. Dick’s 1968 novel Do Androids Dream of Electric Sheep? Roy’s final rooftop scene is one of the film’s most discussed moments.
