A replicant is a fictional bioengineered being in the 1982 film Blade Runner, and in its 2017 sequel Blade Runner 2049. The Nexus-series of replicants are virtually identical to adult humans but have superior strength, speed, agility, resilience, and intelligence, to varying degrees depending on the model. A replicant can only be detected by means of the fictional Voight-Kampff test, in which emotional responses are provoked and a replicant's nonverbal responses differ from those of a human. A version of the test, referred to as a Baseline, is taken by K in Blade Runner 2049 to detect any mental or empathic damage, for which failure means retirement. Throughout the franchise the euphemism "retire" is used when referring to killing Replicants.
