All-American Comics #9

Gary's father's story continues. He discovers he is the only one who can breathe the air outside the domed cities. Gary leads the U.S. forces against the tyrant Rebborizzan, captures him and marries his daughter, Leandra. Gary Jr. is then born. Rebborizzan escapes and kills Leandra, but Gary defeats him again. Now Gary Jr. is the leader of America and the guardian of his father's formula for peace (a foam that puts enemy soldiers to sleep).
