Nastasha Radinov

Also known as "Bloody Pierce", Natasha Radinov was originally an agent for the K.G.B. and Spetsnaz, but when the Soviet Union fell, she contracted her services out as a freelance assassin. She is proficient in almost every deadly hand weapon in the world, but prefers to work with silent weapons, especially a Welrod silenced pistol and a spring-loaded shooting knife designed for Spetsnaz use. She also wears a long coat lined with ballistic nylon and Kevlar, the inside lining holding a vast arsenal of weapons. Radinov prefers to be paid for her services in heroin, which she sells in Russia; she personally stays away from the drug herself.

Recently, she had accepted an assignment to kill Rally and May because the two had interfered in a gun-running operation run by Edward Haints, an Illinois assemblyman running for mayor under a gun-control platform. However, when the first attempt went wrong, and Radinov was injured because of it, she took it as "a matter of pride" and went after Rally personally.
