One idea could be that Batman discovers the reader is pregnant and he struggles with how to protect both her and the unborn child while still fighting crime in Gotham. He might become even more vigilant and start to plan for a safer future for his new family.
I would recommend 'Batman's Unlikely Ally'. In this fanfic, the reader is a normal citizen who unexpectedly becomes important to Batman's fight against crime. It's filled with action scenes and some really sweet moments between the two characters. The way the author describes the relationship development is quite interesting.
First, understand Batman's character. He's a complex, brooding hero. Then, create a unique reader character that can interact with him in an interesting way. For example, make the reader have a special skill or knowledge that Batman needs. Also, set the story in Gotham and include elements like the city's crime and its dark alleys.
The relationship can develop through shared experiences. For instance, they could go through the process of preparing for the baby together, like shopping for baby stuff. Batman, despite his dark and brooding nature, might show a softer side as he anticipates the arrival of the child.
One common theme is the idea of the speed reader being a unique asset to Batman's crime - fighting. Maybe they can quickly analyze evidence or decrypt messages at a super - fast speed. Another theme could be the relationship dynamic, like the speed reader being in awe of Batman's skills and Batman being intrigued by the speed reader's special ability.
It's appealing because it often delves into the emotions and experiences that come with pregnancy. For readers, it can be a way to experience different scenarios vicariously. The fanfic can show how 'x' would support the reader during pregnancy, creating heartwarming and sometimes dramatic storylines. It also gives a chance to explore different aspects of the character 'x' that might not be shown in the original source material, like their nurturing side or how they handle stress in this new situation.
One idea could be a story where Bruce Wayne discovers the reader is pregnant. He might initially be shocked but then quickly becomes protective. He starts making arrangements to keep the reader safe, like beefing up security at their home and ensuring she has the best medical care.
You can start by looking on popular fanfiction websites such as Archive of Our Own (AO3).

A possible plot could be that Catwoman discovers she's pregnant. She then has to decide whether to tell Batman or not.
