Being born a mutant is not always a great thing. Al Rothstein learned this the hard way. His mother was the daughter of the villain Cyclotron who's radiation powers Al would later develop as he got older. But soon the radiation got out of control and Al now needs to wear an armored suit to contain the radiation he produces. His powers make him able to lift about 85 tons, grow to the size of about 15 feet, or allow him to increase or decrease his mass so he can become as hard as a diamond or phase through walls. Taking the name Nuklon Al designed his suit to resemble the one his grandfathers (Al Prat the original Atom and Terence Curtis Cyclotron) wore.
