Obviously, Liza would be the main character. There could also be her best friend, let's say Sarah, who is always there for her during the pregnancy, giving her advice and support. Her mother could also be a character, who might be overbearing at times but means well. And perhaps there's a mysterious neighbor who has some old - fashioned remedies for pregnancy - related issues.
Liza is the main one in this fanfic. Her sister could be a character who has her own experiences with pregnancy and can share some wisdom with Liza. A local midwife, named Martha, could be another character. She could be the one who provides more natural and holistic care for Liza during her pregnancy. And don't forget the baby in her womb, which could be thought of as a character in its own way, as Liza forms a bond with it throughout the story.
One possible plot could be that Liza discovers she is pregnant unexpectedly. Her friends and family have mixed reactions. Some are overjoyed while others are worried about how she will manage. She then has to deal with the physical and emotional changes of pregnancy while also preparing for the new life that's coming.
Obviously, Liza and Tate are the main characters. They are the Gym Leaders in Sootopolis City in the Hoenn region. They are twins and specialize in Psychic - type Pokemon battles.
Obviously, Ranma and Akane are prime candidates. Their relationship is central to the series, so a pregnancy between them would create a lot of drama and interesting storylines. Shampoo could also be involved in some way. Maybe she's jealous and tries to interfere, or she could be surprisingly helpful. Genma, Ranma's father, would also play a role. He might have some old - fashioned or comical ideas about the situation.
Obviously Ladybug would be one of the main characters as she is the one who is pregnant. Cat Noir would also be a main character as he is her partner and would likely be involved in her pregnancy journey, like helping her and being there for her.
Obviously Skye herself is the main character. There could be a love interest who is the father of the baby. Her best friend could also be an important character, providing emotional support and practical help like going to doctor's appointments with her.
Obviously, Hazel and Augustus could be the main characters. Their love story was central in 'The Fault in Our Stars', and a pregnant fanfic could explore their new chapter as a family. They already had a deep connection, and a pregnancy would add a whole new dimension to their relationship.
Melissa's sister could be a great supporting character. She could offer advice based on her own experiences with pregnancy and motherhood. Maybe she helps Melissa with baby shopping and gives her tips on dealing with morning sickness.
Obviously, Neytiri would be one of the main characters as she is the one who is pregnant. Jake would also be a central figure, as he is Neytiri's partner. Their unborn child could also be considered a main character in a sense, as the whole story revolves around the pregnancy.
The main characters would surely be Owen and Blue. Owen as the human who has a special relationship with Blue, and Blue as the pregnant one. Additionally, there could be some other dinosaurs that Blue interacts with. For example, her mate (if she has one) could be another important character, and their relationship could add more depth to the story of the pregnancy.
The father of the baby could be a major character. He could be a loving partner, or there could be some drama if he's not as committed as Lucy. Her best friend could also be in it. The best friend might be the one she confides in about all her pregnancy fears and joys.
