Agnes Cully, better known by her stage name Whitney Frost, is a scientist and an actress living in Los Angeles who used the influence of her husband Calvin Chadwick to experiment with Zero Matter. During her experiments, an accident caused Frost to become infected by the Zero Matter, granting her the ability to absorb her enemies into her skin. Using her incredible intelligence, Frost began experimenting with her new talents while fighting off the investigation of SSR agent Peggy Carter and using her powers to take control of the Council of Nine. However, her quest for Zero Matter clouded her judgement and eventually the SSR was able to trick her and steal the Zero Matter from her, leaving Frost mentally broken and confined to an asylum.
