One likely character could be Edith. Since she is the main female character, a pregnancy for her could add a whole new layer of drama and complexity to the story. Her pregnancy might be intertwined with the mysteries of Crimson Peak, like perhaps the ghosts are drawn to her unborn child for some reason.
One possible fanfiction could involve Edith's pregnancy being a source of both joy and fear. In the dark and spooky world of Crimson Peak, her pregnancy might bring new life and hope, but also attract the unwanted attention of the ghosts that lurk in the mansion. Maybe she discovers some ancient family secret related to pregnancy and the supernatural during this time.
A common theme is the protection of the unborn child. In the dark and foreboding world of Crimson Peak, the mother - to - be might have to fight against the supernatural elements to ensure the safety of her baby. It can also explore the idea of legacy, as the new life represents a new beginning in a place filled with old secrets and tragedies.
Kagome is a likely candidate. She is one of the main characters and has a deep connection with Inuyasha. A pregnancy involving her would add a whole new layer of drama and character development. Also, Sango could be written as pregnant. Given her strong and independent nature, seeing her deal with pregnancy in the world of demons would be an interesting plot. Another possibility could be Kikyo, if the fanfiction takes a different turn on her story. Her relationship with Inuyasha and her own complex character make her a potential candidate for a pregnant character in fanfiction.
Well, obviously Juvia herself is the central character. Her partner would also be very involved. If it's in the context of Fairy Tail, Gray would likely be her partner in the fanfiction, as they have a strong relationship in the original series. Then there are their friends like Lucy, Natsu, and Erza. They would probably be there to support Juvia during her pregnancy, offer advice, or just be there for the big moments.
Friends or neighbors could be characters in the fanfiction. They could offer support, advice, or just be there for some friendly chatter. For example, a neighbor might bring over some home - made food when Nadya is not feeling well during her pregnancy.
Luna could be a great supporting character. She might offer her unique perspective and be very supportive of Ginny. Also, Harry, being Ginny's brother, could play an important role. He could be protective at first but then come to accept the situation. Neville might also be there, perhaps helping out with practical things like gardening to provide fresh produce for Ginny during her pregnancy.
Alice could be a supporting character. She might have visions about Bella's pregnancy and the future of the baby. Jacob could also be involved, perhaps initially being angry or concerned about Bella's situation with Aro. Carlisle could be another one, as his medical knowledge as a vampire doctor could be useful in dealing with Bella's pregnancy.
Obviously Lana herself is the central character. Her Pokemon partners are very likely to be involved. For example, Popplio might be constantly by her side, providing emotional support. Ash and his Pikachu could also be part of the story. Ash, being a good friend, would probably offer his help and advice. Misty might also be there, sharing her own experiences or just being a good friend to Lana during this time. Brock could be involved too, perhaps using his knowledge of Pokemon and nature to ensure Lana has a healthy pregnancy. And other trainers from the Pokemon world who are friends with Lana might make appearances to show their support and be part of the story.
I don't know for sure, but if it's similar to the movie, there might be Edith Cushing. She's often a central character in Crimson Peak - related stories.
The main characters are Edith Cushing, a young and aspiring author. Then there is Sir Thomas Sharpe, the baronet who marries Edith. And Lucille Sharpe, Thomas' sister. These three are central to the story as Edith gets involved with the Sharpes and has to deal with their secrets and the haunted Crimson Peak.
