Nexus-6 (Earth-7149)

Nexus-6 is a series of Replicants first introduced in 2490 by the Weyland-Yutani Corporation to be more human-like in apperance and behavior, and are widely considered to be the main Replicant variant.

Description
Introduced in 2490, the Nexus-6 series of Replicants were developed by the Weyland-Yutani Corporation to appear identical to a human being, albeit possessing superior strength, agility, intelligence, and a wider temperate range tolerance depending on the model for the use in mining operations through the outer colonies.

Physically identical to a human, Nexus-6 can be only identified by the untrained eye by its lack of emotional responses and empathy by a Voight-Kampff machine test. As of 2525, Nexus-6 Replicants were nearly indistinguishable from humans, prompting Weyland-Yutani and other megacorporations such as the Tyrell Corporation to advertise them as "More human than human."

Like all Replicants, Nexus-6 models possess a limited lifespan, in their case, of seven human years.

Despite their advancements, however, Nexus-6 became prone to disobey orders and even grow aggressive in cases against owners and handlers. The subsequent Nexus-8 series corrected these mistakes, making the newer Replicants more obedient.
