Well, you could set the 'pregnant expansion' fanfic in a historical context. Imagine a character in Victorian times dealing with pregnancy while also trying to uphold the strict social norms of the era. It could involve her hiding her pregnancy for a while due to the stigma attached to it at that time. Or perhaps in a science - fiction setting, where the pregnancy is part of an experiment and the character has to deal with the ethical implications as well as the physical changes.
One idea could be exploring the character's journey through pregnancy in a magical world. Maybe she discovers new powers related to her unborn child. Another could be a story where the pregnancy is a catalyst for bringing estranged family members together. For example, the character's mother, who she hadn't spoken to in years, comes to support her during the pregnancy.
A possible idea for a 'pregnant expansion' fanfic is to focus on the emotional growth of the character. As she goes through pregnancy, she might face insecurities about becoming a mother. She could start to question her own abilities and past decisions. The fanfic could show how she overcomes these doubts with the help of her friends or partner, and how this journey transforms her into a more confident and loving person.
In a sci - fi pregnant expansion fanfiction, perhaps an alien species has a unique form of pregnancy that expands their abilities. For example, a female alien might gain telepathic powers during pregnancy that she didn't have before. This could lead to all sorts of adventures as she tries to understand and control these new powers while also dealing with the challenges of carrying a new life.
One idea could be exploring how the character's relationships change. For example, her friends might become more protective or distant. Another could be focusing on the challenges she faces during the pregnancy, like dealing with new powers or responsibilities.
One idea could be exploring the challenges the pregnant raven faces in finding a safe nesting place. Maybe it has to deal with other animals trying to take over its chosen spot.
A great concept for 'rwby expansion fanfiction' is to introduce new kingdoms or regions in the RWBY world. Describe their unique cultures, fighting styles, and Dust usage.

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 really interesting idea could be a fanfic set in a post - war world. Garrus and Shepard are finally at peace, and Shepard's pregnancy is a symbol of a new beginning. The fanfic could explore how they build a home, raise their child, and how their friends and allies interact with the new family. It could also show the challenges of Shepard adjusting to a more domestic life after being a war hero, and Garrus learning to be a father while still being the tough Turian he is.
Well, for Hunger Games pregnant fanfic, you could write about a female tribute who was already pregnant before the Games but kept it a secret. As the Games progress, she starts to show signs of pregnancy, which both confuses and intrigues the other tributes. Or perhaps a story about a Capitol citizen getting pregnant by a tribute she was supposed to be mentoring, and how that causes a scandal in the Capitol society. Also, a fanfic where a pregnant character teams up with other tributes not for the sake of winning but for the sake of protecting her unborn child could be really interesting.

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.
