Synopsis
Per Degaton has once again regained his memories in 1947, and decides this time he will not fail to conquer Earth-2, this time by going into the past to 1942. His plan: use the Crime Syndicate to steal nuclear weapons from Earth-Prime circa 1962 from Cuba during the Cuban Missile Crisis (which in turn caused that world to have a nuclear war) to use for his purposes. Meanwhile, the All-Stars meet up with the JLA and JSA and learn of Earth-Prime’s fate in 1962 from them, and pledge to help out.
