Well, a plot could be centered around Robin's pregnancy in a historical setting. If it's a period piece, she might face different social stigmas and challenges compared to modern times. She could be a single mother - to - be in a society that frowns upon that, and the story could be about her struggle to find acceptance. Or it could be about her pregnancy during a time of war or unrest, and she has to find safety not just for herself but also for her unborn child.
A plot idea could be Robin's pregnancy being a surprise not just to her but also to her family. Her family might have different reactions, some being very supportive while others might be disappointed or worried. The fanfic could then show how Robin overcomes these family issues while also dealing with the physical and emotional changes of pregnancy. Or it could be about Robin's pregnancy in a world where she has some sort of special ability or power, and how the pregnancy affects that ability and how she has to protect herself and the unborn baby from those who might want to take advantage of her situation.
One idea could be that Robin gets trapped in an alternate dimension where the villains are in control and Batman has to figure out a way to bring him back. Another could be a story where Batman is injured and Robin has to take on a major villain alone, learning to trust his own instincts more. Maybe a plot where they encounter a new, powerful ally who turns out to have a hidden agenda that threatens Gotham.
A cool plot could be that there's a mysterious threat targeting all of Batman's allies. Robin and Batgirl team up to not only find out who's behind it but also to protect each other. Along the way, they share some personal stories from their pasts that bring them closer together.
Maybe in a fanfic, there's a magical villain who curses Batman and Robin to be overly ticklish for a day. This forces them to rely on their other skills like detective work and stealth while dealing with this strange affliction. They might also have to ask for help from their allies, leading to some really funny interactions.
One idea could be exploring Robin's struggle to live up to Batman's legacy in the Batman Beyond era. Maybe he has to face a new villain who is specifically targeting the new Batman and Robin duo because of their connection to the old heroes. Another plot could involve Robin discovering a long - lost technology from the original Batman's days that holds the key to stopping a major threat to the future Gotham.
Some fanfics might explore an alternate universe where their roles are different. For instance, Robin could be a powerful mage like Tharja, and they bond over their shared magical abilities. Or perhaps they are from different kingdoms originally and their relationship has to navigate the politics between the two kingdoms while also dealing with their growing feelings for each other. This can lead to a lot of complex and interesting storylines.
One idea could be focusing on the emotional journey of the character. She might feel a mix of overwhelming joy and intense fear. Another could be about the practical preparations for the arrival of four babies, like setting up a huge nursery. Or perhaps the story could revolve around how the family and friends react to this big news.
A possible plot for a 'Ranma 1/2' pregnant fanfic is that it's a result of some magical mishap. This could lead to a search for a way to reverse it, but during that time, Ranma and Akane (or whoever is involved) start to bond in new ways. They could learn more about each other's fears and hopes for the future. Or perhaps it's a plot where an enemy discovers the pregnancy and tries to use it against them, forcing them to come up with creative ways to protect themselves and the unborn child.
Well, they could face a situation where they have to go into hiding during the pregnancy because of the dangerous nature of the clone world. They might find a secluded place where Cosima can have a peaceful pregnancy, but of course, trouble still finds them. Maybe some old enemies track them down, and they have to use their wits and the help of a few trusted friends from the Clone Club to stay safe.
One idea could be exploring how Clary's relationships with her friends and family change. For example, her friends might rally around her to support her during the pregnancy. Another could be the challenges she faces in her daily life, like dealing with morning sickness while still trying to be part of the action in her world. Maybe she has to learn new magical ways to take care of herself and the baby since she's in a unique situation.
One idea could be exploring how Hawkgirl copes with her pregnancy while still having to protect the city. Maybe she has to balance her new physical limitations with her superhero duties.
