This version, known simply as Solar, was a physicist named Phil Seleski. Seleski was a fan of the Gold Key line, especially the adventures of Doctor Solar. One day, Seleski and his colleagues were testing a new type of fusion reactor located in the town of Muskogee. When an accidental breach threatened to obliterate the entire city, Seleski rushed to shut down the reactor. He succeeded, but he was exposed to lethal doses of radiation in the process. However, this did not prove to be fatal, but rather, gave him the ability to manipulate all forms of matter and energy. Seleski tried to use his powers for the good of mankind by attempting to destroy the world's supply of nuclear weapons. The U.S. government attempted to stop him and their efforts caused Seleski to lose control of his powers, which in turn caused Earth to fall into a giant black hole.
