A plotline could involve an ancient prophecy that ties Batman and Wonder Woman's destinies together. They initially dismiss it as superstition, but as events unfold, they find themselves drawn to each other in ways they can't explain. Their relationship then develops as they try to figure out how to fulfill the prophecy while also dealing with their own personal and superhero identities.
One possible plotline could be that Batman and Wonder Woman are forced to work closely together on a mission that spans multiple dimensions. As they face various challenges, they gradually realize their feelings for each other. For example, Batman, who is usually so stoic, starts to open up to Wonder Woman about his past traumas, and she in turn shares her own insecurities about being an Amazon in a man's world.
Perhaps there's a plot where a powerful villain targets their loved ones to force Batman and Wonder Woman apart. This makes them realize how much they truly care for each other. In the process of protecting their families and friends, they grow closer and their romance blossoms as they rely on each other's strengths and skills.
One possible plotline could be that Batman sacrifices himself to save Wonder Woman from a powerful enemy. Maybe he takes on a self - destructing device or holds off a horde of villains while she escapes. Another could be that he is poisoned by a new and deadly toxin, and in his final moments, he imparts some crucial knowledge or advice to Wonder Woman.
In some fanfics, like 'The Amazon, the Bat and the Cat', the plotline involves a magical artifact that can only be retrieved by the combined skills of Batman, Wonder Woman and Catwoman. This forces them to cooperate in a way they haven't before, with Wonder Woman using her strength and magic, Batman his detective skills and Catwoman her agility.
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.
Perhaps Batman discovers a strange artifact that has ties to Wonder Woman's homeland. He seeks her out for help in understanding it, and together they uncover a plot by an ancient evil force that was once sealed away but is now trying to return. Their journey involves not only fighting off minions of this evil but also learning about each other's worlds more deeply.
One common theme is the clash of their personalities. Batman is dark and often cynical, while Wonder Woman is more idealistic. Another is the idea of them being an unexpected couple that surprises those around them.
Yes, there are quite a few. You can find some on fanfiction.net. There are various stories exploring their relationship, from slow - burn romances to action - packed adventures where their love develops amidst fighting villains.
In Batman and Wonder Woman fanfic, 'branches' could refer to different storylines or plot directions. For example, a fanfic might start with a common premise, like Batman and Wonder Woman teaming up to fight a new villain in Gotham. Then, one branch could be that they discover the villain has ties to an ancient Amazonian curse, leading them on a journey to Themyscira. Another branch might involve the villain being part of a secret society in Gotham, which Batman has to infiltrate with Wonder Woman's help.
