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.
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.
One idea could be a story where Batman and Superman have to team up against a common enemy before their big fight actually happens. Maybe a powerful alien threat that forces them to realize they need each other's skills.
Batman and Superman are obviously very popular. They are the main focus of the original movie, so in fanfiction, they often take center stage. Writers love to explore their complex relationship, whether it's a friendship, rivalry, or a combination of both.
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.
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.
In a fanfiction, perhaps there's an apocalypse scenario where Superman is infected with some kind of kryptonite - based virus that makes him go berserk. Batman has to find a cure while also keeping Superman from causing too much damage. At the same time, they are dealing with the general chaos of the apocalypse, like gangs taking over the city and other villains trying to take advantage of the situation.
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 idea could be that they team up to fight a new supervillain who has the power to manipulate time. Batman's detective skills and the female Superman's super strength would make for an exciting combination.
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.
Mercy Graves is an underrated character. In a fanfic, she could be developed more as a complex character. Maybe she has her own motives for being involved in Lex Luthor's schemes. She could be the one who has a change of heart and tries to stop Luthor from pitting Batman and Superman against each other, adding a new layer of intrigue to the story.
