A former college student who was armed by the Overmaster and joined his original Cadre, Nightfall's wristbands can create a null-field of pure darkness, absorbing all light and kinetic energy in a given area. Nightfall used her new gifts alongside the Cadre in battle against the Justice League of America, and still later, as part of Circe's "army" of female supervillains. More recently, Nightfall and the Cadre attempted to take over the world with the help of Dr. Polaris and a captive Controller.
