Wonder Woman could also be involved. She might be caught in the middle, trying to stop the fight at first. But if she realizes that Superman is being a threat for some reason, she could side with Batman, or at least not interfere in Batman's attempt to defeat Superman.
Another plot could be that Batman discovers a new weakness of Superman. Perhaps it has something to do with a certain frequency or energy that Superman is vulnerable to. Batman then builds a device that emits this energy, and during their battle, he uses it to incapacitate Superman. This would be a unique take on the 'Batman defeats Superman' scenario.
Indeed, Doomsday managed to kill Superman in the comics. It was a dramatic and unforgettable scene that changed the course of the story. Many thought Superman was gone for good, but as comics go, there's always a twist.
Doomsday's backstory involves being subjected to extreme genetic manipulation and torture. This made him incredibly powerful and vengeful. He emerged as a force of pure destruction.
In the Superman movies, Doomsday was so powerful because he had the power and soul of the sun. In the manga, Doomsday was the son of the Sun God. The Sun God gave him great power so that he could be compared to the sun. Doomsday's power came from the soul of the sun, which allowed him to use the sun's power, including fire, storm, and light. He also had superhuman abilities that allowed him to manipulate time and space. Therefore, Doomsday was one of the most powerful characters in Superman movies.
