Another plot development could be that Flashpoint Batman tries to convince the regular Batman to change his ways. He might see the regular Batman's methods as too soft or ineffective. This could create a lot of internal conflict for the regular Batman as he questions his own beliefs and methods in the face of this alternate - self's criticism.
Well, it could be about Batman trying to stop the Flashpoint Joker from causing chaos in Gotham. Maybe the Joker has a new and devious plan that only Batman can foil.
Well, obviously the two main characters are Batman from the normal DC universe and Flashpoint Batman. Batman is the well - known Dark Knight, a symbol of justice in Gotham. Flashpoint Batman is from an alternate timeline, with different experiences and a potentially different personality.
Perhaps they could start off as rivals in the fanfiction. Batman from the present is skeptical of Batman Beyond's more high - tech approach. But as the story progresses, they learn from each other and become a great team. For example, Batman could teach Batman Beyond some of his old - school detective skills, while Batman Beyond shows Batman new ways to use technology in combat and surveillance.
Another idea might be that one Batman is from the future and has come back to meet his past self. The future Batman could show the past version some new technologies and tactics, but also warn him about the potential consequences of certain actions. This could lead to self - reflection for the past Batman and a change in his approach to crime - fighting.
The main antagonist would be the Flashpoint Joker. In the Flashpoint universe, he is likely to be even more dangerous and unhinged. He could be targeting Batman directly or causing destruction that Batman feels responsible for stopping. His presence would drive the plot forward as Batman tries to outwit and stop him.
One idea could be that Batman and Superman have to team up to stop a new villain who has the power to manipulate time. This would put their different approaches to justice to the test as they race against the clock.
One idea could be that Supergirl and Batman team up to stop a powerful alien weapon from being used on Earth. Maybe the weapon was stolen from a Kryptonian ship and Batman uses his detective skills to find clues while Supergirl uses her superpowers to fight off the bad guys who have the weapon.
One idea could be that Arrow is transported to Gotham and teams up with Batman to take on a common enemy like Ra's al Ghul. They could combine their skills, with Arrow's archery and Batman's detective and combat skills.
One idea could be that Superman and Batman have to team up to stop a new supervillain who has the power to manipulate time. This would force them to put aside their differences and work together in a really challenging situation.
One possible plot could be that Daredevil and Batman initially clash due to their different methods of fighting crime in Gotham. Daredevil, with his heightened senses, might perceive Batman's more stealthy and high - tech approach as too cold. However, as they face a common enemy, like a powerful and elusive criminal syndicate that operates both in Hell's Kitchen and Gotham, they start to respect each other's skills. They could combine Daredevil's street - level combat knowledge and Batman's strategic planning to take down the bad guys.
