Frank Payne started off wanting to do good. He joined S.H.I.E.L.D. hoping that he could make the world just a little bit safer for his wife and daughter. An undercover operation gone wrong left him a broken man, and he fell into a life of crime, becoming the deadly Constrictor. For years, he has worked as a freelance criminal. Only recently, with the amnesty offered by Superhuman Registration, has he returned to his calling, and begun once again to try making the world a better place.
