One of the original members of
Infinity Inc. (though his first comic book appearance was in All-Star Squadron!), Albert was the grandson of a Golden Age character from Superman named Terry Curtis. In
All-Star Squadron, Roy Thomas turned Curtis into an atomic-powered character named Cyclotron who was forced to work with the Ultra-Humanite to protect his recently-born daughter (who many years later became Albert's mother). Albert's powers of strength and growth are believed to be a result of what originally happened to his grandfather.
In addition to his membership in Infinity Inc, Nuklon was also a member of the post-
Zero Hour Justice League
(of) America which was headed by Wonder Woman. In 1999, Albert joined the JSA and changed his hero identity from "Nuklon" to
Atom Smasher.
