Kyoko

Kyoko was a robot who was physically designed to resemble an Asian woman in her twenties. She was built by a man named Nathan Bateman, who was the CEO of a company called Blue Book. She was based out of Nathan's private mountain estate. Kyoko operated as Nathan's personal servant, preparing food for him, and performing other menial tasks. Nathan Bateman invited one of his employees, Caleb to spend a week at his residence. Caleb was there to perform an analysis on another robot named Ava, but had no idea that Kyoko was a robot as well. Caleb eventually discovered the truth about Kyoko when he sneaked into one of Nathan's private laboratories and found evidence of Ava's predecessors. Although Kyoko was not an A.I., she did perform one critical act of self reliance. She assisted Ava in killing Nathan Bateman. It could be argued that Ava somehow inflienced Kyoko's programming to assist her in this endeavor. Ava escaped the facility following Nathan's death, but Kyoko remained behind.
