Another idea is that the reader is a normal citizen who accidentally gets involved in one of Batman's cases while pregnant. Batman feels responsible for her safety from that moment on. As her pregnancy progresses, he finds himself becoming more attached and starts to envision a different life outside of just being the Dark Knight.
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.
Maybe the pregnant reader has some sort of connection to one of Batman's villains. For example, she could be a former associate of a villain who has turned a new leaf and is now with Batman. This creates a complex situation where the villain may try to use her pregnancy to their advantage, and Batman has to prevent that.
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.
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.
One plot idea could be that the reader is hesitant to tell Bankotsu about the pregnancy at first because she's not sure how he'll react. But then she finally does, and he surprises her with his enthusiasm. Another idea is that they face some challenges during the pregnancy, like a difficult prenatal diagnosis, but they support each other through it.
One idea could be a story where the single mom pregnant reader meets a kind-hearted stranger who offers unexpected support. Maybe at a local grocery store, this stranger helps her carry her groceries and they strike up a conversation that gradually develops into a beautiful friendship that helps her through her pregnancy.
One plot idea could be the challenges they face as a couple preparing for the baby. For example, Lloyd might be worried about protecting the reader and the unborn child from his enemies in the Ninjago world. He could start training extra hard and enlisting the help of his ninja friends to safeguard their home. Another idea is that the reader discovers some special powers within herself during the pregnancy, which are somehow related to the Ninjago realm's magic. This could lead to a whole new adventure as they try to understand and control these powers before the baby is born.
Well, Prussia could be really excited about the pregnancy and start planning all kinds of things for the future. He might want to teach the baby how to fence or other Prussian traditions as soon as possible. He could also be very nervous, especially when it comes to doctor's appointments. He would hold the reader's hand tightly during ultrasounds and be in awe when they see the baby for the first time on the screen. And when the baby kicks for the first time, Prussia's reaction could be really precious. He might be so excited that he wants to tell all his friends right away.
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.
One idea could be a love triangle situation where the reader is a servant in a grand manor served by both Sebastian and Claude. The reader is initially charmed by Sebastian's suave and proper demeanor but then finds herself drawn to Claude's mysterious allure as well. They both compete for the reader's affection in a series of events that involve solving mysteries within the manor and protecting the master.
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.
How about 'The Adventures of Ratbag and Reader'? It gives a sense of an ongoing story between them.
