Well, his communication devices might face interference due to the different technology levels or the magic that might be present in Themyscira. However, Batman is resourceful. He could use the natural resources on the island along with his gadgets. For instance, he could combine a local plant that has conductive properties with his own electrical gadgets to create a new device or improve an existing one.
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.
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.
Well, one way it could work is if there was some sort of multiverse crossover. Maybe Batman gets transported to the wizarding world and finds himself in Hogwarts' Great Hall. He'd be quite the oddity there, with his high - tech gadgets among all the magic. He might initially be on guard, sizing up the situation, trying to figure out how to get back to Gotham while also being intrigued by the magical environment.
The plot could start with Batman's plane crashing on Themyscira. He wakes up to find himself surrounded by the Amazons. At first, there is tension as the Amazons are not used to male visitors. But Batman's honor and sense of justice quickly earn him some respect. He could then team up with Wonder Woman (who is from Themyscira) to fight a common enemy that threatens both Gotham and Themyscira. This could involve a villain who has found a way to steal the power of the Amazons and wants to use it to take over Gotham as well.
In a 'batman crashes on themyscira' fanfic, the story could start with Batman testing out a new experimental Bat - vehicle. There's a miscalculation or an attack during the test flight that sends him crashing onto Themyscira. The Amazons, led by Wonder Woman, are cautious. Batman, being the resourceful hero he is, tries to adapt to this new environment. He might learn about their culture while also trying to find a way to get back home and prevent any harm that his presence might bring to the island.
Batman's brooding and serious personality would likely have a big impact on Shazam. Shazam is more light - hearted and naive, so Batman's influence could make him more cautious. For example, Shazam might not rush into battles as quickly.
Batman would be heartbroken. He has trained Robin and sees him as a partner and almost like a son. He would first try to talk to Robin, to find out what made him turn evil. He would hope that he could reason with Robin and bring him back to the good side.
Sasuke would likely be aloof and guarded at first. He might see Batman as just another 'vigilante' like some of the shinobi in his world. Batman, on the other hand, would be cautious and try to figure out Sasuke's motives. Eventually, they could start sharing their combat techniques. Sasuke might show Batman how to use chakra in combat, and Batman could teach Sasuke about the importance of having a strong moral code.
Batman would fit in by being the ultimate strategist. The Avengers sometimes jump into action without a fully thought - out plan. Batman's meticulous planning would force them to be more organized. He could also provide a more grounded perspective. Many of the Avengers have superpowers and deal with large - scale threats from outer space or magic realms. Batman, coming from the streets of Gotham, would remind them of the importance of protecting the everyday people.
Batman's character would experience a significant transformation. Initially, he would be resistant to the idea of being Darkseid's advisor. However, as time goes on, he would adapt to the situation in order to survive. His moral compass would be severely tested as he would be forced to make decisions that go against his usual principles. He might become more calculating and less trusting of others, even his own allies. This new experience could also give him a deeper understanding of the cosmic threats that exist beyond Gotham, which could potentially change his approach to protecting the world once he manages to break free from Darkseid's grasp.
Obviously, Batman would be one of the main characters. He is the one who lands on Themyscira. And Wonder Woman would also be a key character as she is from Themyscira and would likely play a role in how Batman is received on the island.
