While in this alternate universe, the heroes team with the Wonder Woman in 1942 to fight against a Nazi criminal by the name of Agent Axis II, while also dealing with the threat of the creature known as Ravager, which is causing massive disruptions between Earths One and Two.
The effort of the heroes are rewarded when they find a way to stop both villains and restore their timelines to normal.
