Another idea could be the contrast between Batman's brooding and often solitary nature and the more community - based and female - dominated society of Themyscira. This could lead to some character development for Batman as he learns new ways of interacting and trusting others.
A cool plot for themyscira crossover fanfiction could be a time - travel crossover. For example, a Themyscira character travels to the future and has to deal with advanced technology and different social norms. They could end up in a post - apocalyptic world and use their skills to help survivors. Or perhaps a crossover where a Themyscira warrior is magically transported to a world of fairytales. She has to navigate through the strange rules of that world, like dealing with talking animals and evil witches, all while trying to find a way back to her home on Themyscira.
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.
Some of his gadgets might not work as effectively in Themyscira. For example, his grappling hook might not find as many suitable places to attach to in the more natural and less urban landscape. But he could also adapt them. Maybe he uses his batarangs to cut through the thick vines or uses his utility belt items in creative ways to communicate with the Amazons.
One idea could be a story where Robin has to take on Batman's role temporarily when Batman is injured. He has to face a powerful villain all on his own, using the skills Batman taught him in a new and creative way.
One idea could be a crossover where Naruto is transported to Gotham City. He might use his ninja skills to help Batman fight the villains in a new and unexpected way. For example, his ability to move quickly and stealthily could be a great asset in tracking down the Joker.
One idea could be a story where Batman and Hawkgirl team up to stop a powerful villain that is causing chaos in both Gotham and Hawkgirl's home realm. They start off not trusting each other fully due to their different methods, but as they face challenges together, they learn to respect and rely on one another.
One idea could be a crossover where Batman and the Turtles team up to take on a common enemy like the Foot Clan and some of Batman's rogues gallery working together. Maybe they meet in Gotham City and have to adapt to each other's fighting styles.
One idea could be a story where Batman and Wolverine team up to take on a powerful new villain in Gotham City. The contrast between Batman's high - tech gadgets and Wolverine's brute strength would make for an exciting dynamic.
In some Punisher Batman fanfiction, the setting might be a Gotham overrun by more extreme and violent criminals. The Punisher could come to Gotham thinking he can clean it up better than Batman. This would lead to a power struggle and also a chance for them to learn from each other's techniques.
You could also do a 'what if' scenario. For instance, what if Batman had to team up with some of the Arkham inmates, like Harley Quinn and Poison Ivy, to stop a greater threat that was endangering not only Gotham but also the inmates' own lives? This would involve exploring their complex personalities and how they might interact with Batman in a different context.
