World’s Best: Time Bomb
by Libbylawrence 
A bomb displaces Superman, Red Robin, Lois Lane Kent, and Power Girl through the time-stream! In Camelot, Superman assists his adoptive ancestor Brian Kent the Silent Knight against another descendant — Harvey Kent, alias the criminal Two-Face! In the 1920s, Red Robin meets a young Bruce Wayne in training as the original Robin with detective Harvey Harris! In the 30th century, Lois Kent helps Craig King, the Superman of that era, against a menace from the past! And Power Girl is sent back to the 1950s, where she assists Team Justice as Lightning Girl!
