Crisis of two earths

The story takes place in a third earth that is different from Superman and others, and the superpowers of this parallel world of Earth are all villains, and the evil forces rule the United States by the evil alliance, and even the government does not dare to deal with them. The members of the Justice League on Third Earth are only Lex Luthor and the Joker who break into the enemy headquarters and steal the time transferr, but the Joker leaves Rex to block the pursuit of the members of the Evil Alliance and dies with Jed Jax and his Blood Hawks, and Rex flees the Third Earth to first earth to ask the Justice League for help. At this time, the members of the Justice League in the First World are busy working to renovate the base, and they were suspicious when Superman and the others heard Rex's request from Third Earth, but after confirmation and discussion, Superman, Wonder Woman, Green Lantern, Flashman, and Martian Manhunter decided to get up and head to Third Earth, while Batman chose to stay at the base alone because of concerns about the safety here.

Upon reaching the enemy base on the Third Earth, the six begin to confront Owl, The Magic Woman, and several of their men (all on the righteous side of the First Earth), and after a great battle in the air, the six are victorious. After Superman and the others arrive at the Third Earth Joker's base to make plans, Superman and Rex decide to go together to fight Superman, who was once suppressed by the enemy but defeated by two due to Rex's Kryptonite. The other four took advantage of the night attack on high-speed Johnny and his men who were restocking at the dockside, and won another victory, and the high-speed Johnny immediately fled after the Power Ring detected that the Justice League had attacked the port and went back to inform the organization. On the other hand, the defeated Demon Superman was released by President Slade, so the unwilling Superman and others went to the President of the United States, but were beaten back. The president's daughter is a person who often speaks to lead the people to overthrow the Evil Alliance, she believes that her father should be a fearless hero, but he has become cowardly due to the oppression of the Evil Alliance, martian manhunters say that the president is because he understands the preciousness of life, and then Martian manhunters volunteer to become her sponsor, but also make the two fall in love.

On the other hand, Owl man and supergirl are busy making weapons quantum native bombs, wanting to use their bombs to rule the universe, in fact, Owl is going to detonate the first earth with a quantum native bomb in an attempt to destroy all parallel earths, but no one else knows about this. Supergirl then arrives at the Justice League base on First Earth with three of her strong men to retrieve another time-shifter stolen by Rex, and engages Batman and reinforcements Aquaman, Black Canary, Black Lightning, Red Whirlwind, and Firestorm on the watchtower. After the Black Lightning defeated three of his men, Batman was fighting Supergirl alone, facing the powerful Supergirl Batman at a disadvantage, and finally Batman used his skills to unconscious his opponent and also went to the Third Earth to contact his companions.

After finding out the location of the Evil Alliance, the Justice League and Rex (martian manhunters have no counterparts) went with the magic supergirl trapped with steel, and using the ability of the Green Lantern, the party quickly broke into the enemy camp, and the evil alliance put down their work to meet the battle. Halfway through the battle with their respective enemies, Owl completed the Quantum Native Bomb and teleported directly to the first Earth along with himself, at which point Superman and the others realized that something was wrong with Owl's behavior and the two sides stopped fighting. Although Supergirl hastened to explain but it was ineffective, Rex also said that someone needed to move at high speed to make Batman activate the portal to get there, Batman thought that Flash's limit might not be achieved, and when High Speed Johnny volunteered that he could, Batman successfully reached the wild planet where Owl man was located, and the two fought a duel. Although Obelie almost had the upper hand, he was trapped by Batman with a rope as the countdown to detonation was about to start, and Batman simultaneously teleported the bomb to Earth thousands of years later, after Batman fled, Owl said "it doesn't matter" and abandoned the stop system, and Owl died. After the success of the stop operation, the high-speed Johnny died of aging due to the effects of high-speed movement. After President Wilson and the U.S. military arrested the remaining remnants of the Demon Superman, The Magic Supergirl, and the Power Ring, the President thanked the Justice League members quite much, and left the former Martian Manhunter and the President's daughter to kiss and say goodbye. After returning to the First Earth base, Wonder Woman takes Owl's stealth plane as a trophy, and Batman and Superman show a relaxed expression to greet the five heroes including Aquaman who is still at the base, and the incident ends.
