Maybe in a fanfiction, there's a parallel universe where Batman Beyond and Wonder Woman are part of a super - hero alliance against an alien invasion. Wonder Woman could lead the charge in direct combat, while Batman Beyond uses his detective skills to figure out the aliens' weaknesses. Their relationship could start off rocky as they have different ways of approaching problems, but they learn to work together effectively.
Maybe there's a fanfic where a child is accidentally caught in the middle of a battle between Batman and some of his rogues gallery, and Wonder Woman steps in to save the child. The child then becomes sort of a mascot for the two heroes, inspiring them to work together more closely and also showing the softer side of the often - brooding Batman.
One idea could be that they go to a rooftop in Gotham City. Batman sets up a simple yet elegant dinner with candles and food from his favorite local diner. They talk about their different approaches to justice, with Wonder Woman sharing tales of Themyscira and Batman discussing his no - kill rule and how it sometimes complicates things. It's a night of deep conversation and connection.
Perhaps in a fanfiction, there's a parallel universe where Batman and Wonder Woman are the rulers of a united Gotham and Themyscira. In this world, their pregnancy is seen as a symbol of the union between their two kingdoms. However, there are still those who oppose the union and try to harm Wonder Woman during her pregnancy. Batman then has to use all his resources and skills to protect his family and his kingdom. The story could explore themes of love, loyalty, and the challenges of ruling while also dealing with the joys and difficulties of impending parenthood.
In a fanfiction adventure, they might team up to stop a mad scientist who is creating dangerous hybrids of humans and animals. Batman Beyond uses his detective skills to track down the scientist's lair, and Wonder Woman uses her combat skills to fight off the hybrids. Along the way, they have to also deal with the ethical implications of the scientist's experiments.
One idea could be that they meet during a big battle in Gotham City. A powerful villain has brought chaos and Wonder Woman arrives to help. Batman is initially suspicious of her but soon realizes they share the same goal of protecting the innocent.
One possible storyline could be a team - up against a new, powerful villain who is causing chaos in Gotham and Themyscira. Batman Beyond with his high - tech gadgets and Wonder Woman with her strength and magic could combine their skills. Maybe the villain has the ability to disrupt time and space, forcing them to travel to different dimensions to stop him.
Good fanfic writing also involves creating believable interactions between the characters. Batman Beyond might be a bit more cynical and used to working alone in the shadows, while Wonder Woman is more open and confident. Their conversations should reflect these differences. Also, don't be afraid to put them in new and unexpected situations. Like, what if they were both shrunk down to a microscopic size and had to fight tiny villains inside a high - tech device? This would force them to rely on each other in ways they haven't before.
One idea could be that Batman and Wonder Woman are investigating a series of strange disappearances in Crime Alley. They discover that an old enemy has returned and is using the alley's seedy underbelly to conduct experiments. Batman uses his detective skills while Wonder Woman uses her strength and wisdom to fight off the henchmen and ultimately face the main villain.
She could be devastated. Wonder Woman might go into a period of mourning, isolating herself from others as she grapples with the loss. She was used to having Batman as an ally, and his death would leave a big hole in her life.
In a different scenario, Batman is transported to the realm of Athena in some sort of magical accident. There, he has to prove himself worthy to her. He learns from her about justice in a different light, not just the street - level justice he's used to in Gotham. When he returns to Gotham, he has a new perspective on how to deal with crime and corruption.
