the Freedom City Chronicles
Nuclear Winter can generate bio-radioactive blasts and fly. As a strange side-effect of her treatment, she is apparently immune to the cold.
Valentina Zaitsev was a world class ballerina when she was critically injured in a car crash. Because of her fame she was taken to a secret government clinic where she was treated with experimental procedures that used radiation to boost her natural healing. Her body absorbed the radiation at an alarming rate, giving her amazing powers and the ability to generate powerful pulses of Bio-Radiation. She accepted an offer to join the People’s Heroes after her dancing career ended.
Years later, Valentina is still beloved by the Russian people and is easily the most popular celebrity in the country.
