In some batman and xmen fanfiction, you might see Jean Grey using her telepathic powers to help Batman get inside the mind of a particularly difficult villain he's been trying to understand. This could add a whole new dimension to Batman's detective work.
A really cool crossover could involve the X - Men's Danger Room technology. Imagine Batman getting a chance to train in it. He could learn new combat techniques and test his skills against some of the X - Men's toughest challenges. It would be a great opportunity for both worlds to learn from each other.
One interesting crossover could be Batman teaming up with Wolverine. Their different fighting styles, Wolverine's brute strength and healing factor along with Batman's gadgets and strategic mind, would make for an exciting story.
One interesting crossover could be Ben using his alien forms to help Batman fight Gotham's villains in a more unique way. For example, Heatblast could be used to deal with Mr. Freeze in a direct heat - based battle.
One interesting crossover could be a story where Daredevil and Batman team up to take on a common enemy like the Joker and Bullseye working together. They would bring their unique skillsets. Daredevil's enhanced senses could help in detecting hidden threats, while Batman's gadgets and detective skills would be crucial in uncovering the villains' plans.
One interesting crossover could be a story where Spawn and Batman team up to take on a common enemy like a powerful and corrupt crime syndicate that has connections in both Gotham and Spawn's city. They would have to overcome their differences in methods, with Batman relying on his detective skills and non - lethal gadgets, while Spawn uses his more brutal and supernatural powers.
One interesting crossover could be in a courtroom setting. Imagine Phoenix Wright from Ace Attorney defending Batman in a Gotham court. Batman's rogues' gallery could be witnesses, and Phoenix would have to use his legal skills to prove Batman's actions were just. Another crossover could involve the investigation aspect. Batman's detective skills combined with the Ace Attorney's unique way of uncovering evidence would make for an exciting story. For example, they could be investigating a crime that has ties to both Gotham and the Ace Attorney universe, like a new villain using legal loopholes to commit crimes.
One interesting crossover could be Batman finding himself in the One Piece world. He might be initially confused by the Devil Fruits and the strange sea creatures. Maybe he teams up with Luffy to take on a common enemy who has both high - tech weapons like in Gotham and the strange powers of the One Piece world. Another could be Robin or Nami being interested in Batman's gadgets and trying to reverse - engineer them.
A possible crossover in fanfiction could involve Wednesday Addams becoming an apprentice of Batman. She has her own sense of justice and a no - nonsense attitude. Batman could train her in his ways, but she would also bring her own Addams Family charm to the Batcave. She might decorate it in a more gothic and spooky way, and her dark humor could lighten up the often - brooding atmosphere in Batman's world. This could lead to some really fun and unique adventures as they fight crime together in Gotham.
One interesting crossover could be Batman getting his hands on the Death Note. He would likely be very conflicted about using it. On one hand, he could potentially rid Gotham of its worst criminals without having to physically fight them all. But his strong moral code would probably prevent him from using it, as it goes against his belief in justice through the legal system. Another aspect could be L from Death Note trying to figure out Batman's identity, using his detective skills which are somewhat similar to Batman's own.
Another possibility is that the villains from both universes team up. The Joker could make a deal with Rita Repulsa. Batman and the Power Rangers would then have to put aside their differences in fighting styles and ideologies to take on this combined threat. The Rangers' zords and Batman's gadgets would both be crucial in this epic battle.
One interesting crossover could be Batman finding himself in the world of Game of Thrones. Maybe he uses his detective skills to solve some of the mysteries in Westeros, like the true identity of Jon Snow's parents before it was revealed in the show. He could also use his gadgets to fight the White Walkers, giving the people of the Seven Kingdoms an edge in the battle against the undead.
One interesting crossover could be Blue Beetle seeking Batman's guidance on how to better protect his city. Batman, with his years of experience, could offer strategic advice to Blue Beetle. Another could be them teaming up against a common enemy like Ra's al Ghul. Ra's has complex plans that would require both their skills to stop.
