Nuklo is the son of Robert Frank and Madeline Joyce, also known as the Whizzer and Miss America. He was born in the fictional town of Mount Athena, New York (where Project Pegasus is also located). The two retired from their careers as costumed crimefighters several years after the end of World War II, married, revealed their identities to the government, and took jobs at one of the nation’s first nuclear power plants. When a radiation experiment went awry, the Franks rushed into a high radiation area to manually activate the damping rods that were malfunctioning and were exposed to massive amounts of radiation. Madeline Frank was pregnant at the time and when she gave birth eight months later, her son proved to be a mutant who emitted toxic radiation levels. (Apparently, due to their own superhuman powers, the Franks were immune to the deleterious effects of excessive radiation.) The Franks were persuaded by the government to place their infant son in a special capsule which would retard his aging process while draining him of excess radioactivity.

The capsule lay beneath the basement of a government building for several decades, until the building collapsed and the capsule was taken into custody by the Avengers. By that time, the classified records about the capsule had been misplaced and forgotten. But while Madeline had died shortly after giving birth to a second stillborn son a few years later, the Whizzer was still alive and learned about the capsule’s discovery. He broke into the Avengers’ Mansion to take custody of the capsule but was prevented from doing so by the Avengers. Shortly thereafter, the Avengers’ probing devices tripped the release mechanism of the capsule and Robert Frank, Jr., was set free. His body, which had only aged approximately twelve years over the decades of containment, was still highly radioactive, and soon exhibited certain superhuman powers. His mind, which was of above average intelligence, was still childlike and he knew absolutely nothing about the outside world and was consequently greatly disoriented. Somehow fissioning into three separate duplicates, Frank Jr., who would soon dub himself Nuklo, ran amok through New York City. The Avengers subdued the three doppelgangers and brought them together, which merged them into a single being again. Nuklo was rendered unconscious by a hex cast by the mutant Scarlet Witch, who at that time believed herself to be his sister.
