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!
Kara Zor-L is a woman with an unusual upbringing, having grown up in the virtual-reality world created by the Symbioship. In an effort to connect with her roots, Red Robin brings Power Girl back in time to Krypton to meet her parents, and the two modern-day heroes become the Kryptonian heroes Nightwing and Flamebird! Back in the present, Power Girl tries to solve the mystery of her missing cousin Superman, leading her on a greater quest throughout time and space, while fighting Colonel Future and the Futurian, the Yellow Peri, and Alexei Luthor! But while she has adventures ranging from a second career as a short-lived Golden Age mystery-woman to exploring the microcosmos, her greatest concern is reconciling her relationship with her cousin after being angry at him for so long.
