Jocasta (T'Nia Miller)

Jocasta is a synthezoid whose mind was derived from the scientist Jo Carrington. Bent on unleashing her nanite creations to the world so that all humans would be under her will and control, she killed the original Carrington's co-representatives of Markridge Biotech and obtained most of their biometrics. Jocasta crossed paths with White Vision, who tried to stop her, and though he failed, Jocasta met and grew a romantic connection with Ultron, who decided to aid her in her goal.
