Cynthia Kazakov was a research specialist from Humani and is the good friend of Valerie Blaylock, whom she meet in medical school. She has helped out in numerous medical developments, like the myocardial patch.
She was dating a man called Ray Kerensky, who was actually Master Vakhushti. She was spying on Caduceus and the Army while providing help to Parnassus in Stigma research. When Vakhushti broke up with her, she went to confront him, where he installed a pump unit and chip designed to kill her via remote control if she went astray. When the Army raided the Parnassus Hideout, Markus and Valerie operate on her to remove the chip.
