What are some interesting plot ideas for a 'Batman meets Wonder Woman' fanfic?

One idea could be a misunderstanding. Maybe some false information makes Batman think Wonder Woman has been compromised and he has to stop her. Another could be a competition for a powerful, mysterious artifact that they both believe they should safeguard. And a third idea could be a mind - control situation where Wonder Woman is being controlled by an enemy and Batman has to fight her to break the control.

A fanfic could explore a scenario where Batman is framed for a crime on Themyscira. Wonder Woman doesn't believe he's guilty and they have to work together to clear his name while also uncovering a conspiracy within her own homeland that threatens both their worlds.

Maybe in the fanfic, there is a threat to the entire world that only the combination of Wonder Woman's Amazonian knowledge and Batman's technological resources can solve. For example, an ancient artifact has been stolen and is being misused. They start off not trusting each other fully but as they work together, they develop a deep respect.

A great plot for this fanfic could be that a mysterious force is causing chaos in both Gotham and Themyscira. Batman and Wonder Woman join forces to investigate. Along the way, they discover that the source of the problem is related to an old grudge between two long - forgotten groups. As they dig deeper, they also explore their own feelings for each other and how their different approaches to justice can be reconciled.

One plot idea could be that an otherworldly threat emerges that only their combined powers can stop. They have to put aside their differences and work together seamlessly. For example, a powerful alien race plans to invade Earth and they need to use Batman's strategic mind, Superman's super strength and Wonder Woman's combat skills.

A possible plot is that a powerful magical object has been stolen by a group of rogue Lemmins. Batman and Wonder Woman get involved as this object has the potential to cause chaos in the entire DC universe. They journey to the Lemmin homeland, which is a beautiful but dangerous place filled with floating islands and strange energy fields. As they search for the object, they learn more about the Lemmin society, their social hierarchies, and their unique forms of magic.

One idea could be that Batman and Wonder Woman have a major disagreement over how to deal with the Injustice regime. Batman wants to use more stealth and subterfuge while Wonder Woman believes in a more direct approach. This could lead to some intense battles between them, not physical but more of a battle of wits and ideologies.

One idea could be that Batman and Wonder Woman are both vying for the attention of a new superhero in town. Batman is jealous because Wonder Woman seems to have a natural connection with this new hero, perhaps due to their similar powers or backgrounds. Wonder Woman, on the other hand, is jealous of Batman's detective skills which the new hero seems to admire a great deal. This could lead to a series of challenges and competitions between Batman and Wonder Woman to prove who is more worthy of the new hero's friendship or alliance.

A possible plot could involve a mind - control situation. An evil sorcerer manages to put Robin under his spell and sends him to attack Batman and Wonder Woman. They are reluctant to fight Robin but have to find a way to break the spell without harming him. Meanwhile, they also need to stop the sorcerer from using Robin to carry out more devious plans, like stealing secrets from the Justice League.

One idea could be that a powerful new villain emerges who is a threat to both Gotham and Themyscira. Batman and Wonder Woman team up to track down the villain's lair. Batman uses his detective skills to analyze the clues while Wonder Woman uses her combat skills in the battles along the way.
