The 5 earths and their universes are temporarily safe, as a captive Flash and Psycho Pirate witness the reemergence of the Anti-Monitor with a new plan to create an antimatter cannon. Using the Pirate to emotionally control the Anti-Monitor's Qwardian Thunderers as a diversion, Flash enters the cannon and runs counterclockwise to cause its energies to build up, thus exploding and destroying the cannon. The Anti-Monitor throws Flash throughout time, killing him, and absorbs the entire energy of the anti-matter universe for a final attack.
