A conscious synth built to be Leo's sister, assigned to work as a prostitute when they were separated. She is violent and resentful of humans and wishes to live her own life, but later starts to care about humans. In the second season, she uploads the consciousness program to the synth network, but only a few synths are upgraded with it at a time rather than en masse. After a brief relationship with Astrid, Niska returns to the Hawkins and asks to be tried as a human for her crimes.
