[Western Crossover] Restarting the Fight to Save the World

Superman has gone mad, and the world lies shattered. As the last major force opposing Superman, Batman has no choice but to call on the power of the Sorcerer Supreme and travel back in time to save the world, hoping to avert disaster. The first time, Lois died because of the Joker, and Injustice Superman was born. The second time, Barry the Flash died because of the Joker, and Lord Superman was born. The third time, Batman decisively killed the Joker, hoping to stop Superman from going mad. Unfortunately, Superman didn't go mad. Batman did first, and the Batman Who Laughs was born. The fourth time, the fifth time, the sixth time... The Dark Knight no longer remembered how many times he had failed. Until the final time, the Knight opened his eyes in the darkness. The world couldn't take it anymore and rebooted. But things did not take a turn for the better. Carrying the memories of countless parallel universes, he discovered that in the rebooted world, the Flash and Lois had both died because of the Joker, even though he had already killed the Joker. Excellent. Injustice, Lord, and the Batman Who Laughs: all the conditions are met. This is just wonderful. Thinking this, Batman decided to try a different way of saving Superman this time. For instance, he could start by beating some sense into the Superman who was on the verge of turning completely evil. PS: The Flash will survive. This is probably a story about [You went dark, so I'll go even darker, then forcefully set you on the path to redemption and save the world]. The blurb and idea have been archived.
