Gary Concord Sr., a 20th-century scientist, had devoted his life to finding the means to end war. In 1950, an accident put him into suspended animation. He awoke as a chemically altered superhuman in the year 2174. His son, Gary Concord Jr., is born in 2214 to the lifespan-lengthened Gary Sr. and wife Leandra – daughter of the tyrant Rebborizon, whom Gary Sr. defeated. Rebborizon eventually returned to kill his own daughter, however, prompting Gary Sr. to kill Rebborizon in return.
