Altered by the radiation of an alien genebomb detonated in Earth's orbit, Joseph Martin's otherwise mundane life was irreversibly changed.
With no intent on using his new found abilities for crime, Martin was assaulted by three hoodlums which left him with severe head injures. His injures caused mental damage and Martin lost his grip on reality claiming he was an old movie hero called the Atomic Skull.
