There could be a fanfiction where Batman and Superman are transported to an alternate dimension. In this new world, they find that their roles are reversed. Superman is more of a brooding, nocturnal figure, while Batman has super - like abilities. The story would be about how they adapt to this new situation and still find a way to be heroes in this strange world.
One idea could be that a powerful new villain emerges who has the ability to manipulate both Batman and Superman's minds. This forces them to fight against each other while the real enemy is pulling the strings. Another could be a situation where Gotham and Metropolis are in a territorial dispute, and Batman and Superman initially take sides based on their cities, but then realize they've been played.
One idea could be that Batman discovers a new Kryptonian weapon that Superman unknowingly has a weakness to. This weapon was hidden on Earth long ago by a rogue Kryptonian. Batman then has to decide whether to use this knowledge to defeat Superman or find a way to help Superman overcome this potential threat together.
A plot in the fanfiction could be about Lois Lane being the key to preventing the fight. She discovers a secret that proves both Batman and Superman are being used in a political game, and she has to convince them to trust each other. In this way, it would add more depth to her character as more than just a damsel in distress. For example, she could use her journalistic skills to uncover the truth behind the forces trying to pit the two heroes against each other.
One popular website for fanfiction in general is Archive of Our Own (AO3). It likely has a good collection of 'Batman v Superman' fanfictions. Another option could be FanFiction.net, which has been around for a long time and has a large variety of fan - created stories.
One interesting story could be where Superman's obsession leads him to constantly protect Batman in a very overzealous way. He might be there at every crime scene Batman shows up at, much to Batman's annoyance at first but then they gradually develop a deeper understanding. Another could be a story set in an alternate universe where Superman's obsession is due to some sort of mind - control and Batman has to figure out how to free him from it while also dealing with his overly affectionate and protective behavior.
In some fanfiction, Superman might carry Batman while they are on a mission to a far - off planet. Batman, being a normal human (albeit a highly trained one), needs Superman's flight ability to reach the destination quickly. This could lead to some interesting dialogues between them as they travel through space, with Batman analyzing the situation and Superman just focused on getting there.
No, Batman v Superman wasn't originally presented as a story in the comics. It was created specifically for the big screen.
Yes, Batman v Superman storylines have appeared in comics over the years.
The batman v superman story is complex. Batman, who has been operating in Gotham, becomes concerned about Superman's unchecked power. Superman, on the other hand, is just trying to do what he thinks is right for the world. Lex Luthor manipulates events to make Batman target Superman. However, as the story progresses, they realize they need to work together against a common enemy like Doomsday.
A really cool plot could be a 'what if' scenario. What if Superman was raised in Gotham instead of Metropolis? How would his powers and values be different? And how would Batman react to having a super - powered being in his city from the start? In this fanfic, we could explore their relationship in a completely new light.
