Superman and Booster Gold travel back in time to verify the claims that Kal-El's father somehow survived the destruction of Krypton. What they find, though, is a vastly different world than history has shown. When the time intruders are discovered, Jor-El and General Zod collaborate to capture or destroy them. The Eradicator will chase the pair through time to 25th-century Gotham City and back to Krypton in pursuit of justice. Collecting ACTION COMICS #993-999 and a story from ACTION COMICS SPECIAL #1.
