A "replicant" is a bioengineered being designed to resemble a human. They are often created for specific tasks, such as labor or companionship, and possess advanced artificial intelligence. Replicants are featured prominently in the science fiction film Blade Runner, where they raise questions about identity and humanity. In the Blade Runner universe, replicants are manufactured by the Tyrell Corporation and are often used in off-world colonies. Due to their enhanced abilities, they are sometimes viewed as a threat, leading to the need for "blade runners" to track down and retire rogue replicants.
