One possible way is that Batman is so dedicated to his mission in Gotham that he prioritizes it over his relationship with Wonder Woman. He might cancel dates or important moments with her because of a crime wave or a new villain in his city. This repeated neglect could break her heart as she realizes she'll always be second to his crusade.
In some fanfiction, Batman might break Wonder Woman's heart by being overly secretive. His constant need to keep his plans and emotions hidden could make Wonder Woman feel like she's not truly trusted or close to him. This lack of transparency could lead to her feeling unloved and ultimately heartbroken.
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.
A common plotline could be that Batman gets involved with another female character. Maybe he starts to develop feelings for Catwoman due to their shared history of being on the wrong side of the law sometimes. This new relationship on Batman's part could make Wonder Woman feel betrayed and her heart broken.
One possible plot could be that Batman, due to his brooding nature and fear of getting too close, does something that shatters Wonder Woman's heart. Maybe he lies to her about his true feelings or betrays her trust in some way related to their superhero duties.
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.
Wonder Woman could become a more complex character. The heartbreak from Batman might make her question her own judgment in relationships. She might become more cynical about love. Batman, initially, might seem unchanged on the outside, but internally he could be a mess. As time passes, he could be haunted by his actions and this could lead to his own character development. He might start to open up more to his friends and allies, realizing that shutting everyone out is not the answer.
After the proposal, their relationship would likely become more public. They would no longer be just comrades in arms but an engaged couple. Their interactions would be more affectionate and they would start planning a future together.
At first, it might be a bit rocky. Batman is used to working alone and being in control, and Wonder Woman is a powerful and independent hero. But as they face challenges together, they would start to respect each other's abilities. They could develop a friendship based on mutual admiration for their different skills.
Yes, it can be quite popular. Many fans are drawn to the idea of these two iconic DC characters having a romantic relationship in fanfiction. Their different personalities and powers make for an interesting dynamic, and it allows for creative exploration of their characters in a more intimate context.
One possible fanfiction could be that in an alternate universe, Batman and Wonder Woman have a relationship that leads to pregnancy. Maybe it starts with a mission where they have to work closely together for an extended period. As they face various challenges side by side, they develop a deep emotional bond that blossoms into love. The pregnancy could then be a source of both joy and concern, as they have to balance their superhero duties with the impending arrival of a child. They might worry about how the child will be received in the world of superheroes and how to protect it from their enemies.
It would be a very unique relationship. Batman would be the more cautious and protective parent, always worried about her safety given his own experiences. Wonder Woman would be the one to encourage her to embrace her powers and use them for good. Their daughter would look up to both of them, learning from Batman's intelligence and Wonder Woman's strength.
