Tony Hutchinson could also be an interesting choice if the fanfiction takes a different turn. For example, if his partner gets pregnant and he has to deal with his own insecurities and past experiences while supporting her through the pregnancy.
Another option is Mercedes McQueen. Given her strong personality, her pregnancy would be filled with drama. She might have to face her enemies while also preparing for a new life as a mother, and the story could explore how she uses her wits to overcome the challenges.
It could be one of the female characters like Callie. Since she has a complex backstory and strong personality, her being pregnant would bring a whole new dimension to her character arc.
It could also be one of Yankumi's students' mothers. This would show a different perspective. The mother might be struggling with her pregnancy while also dealing with her child's issues at school. Maybe she looks to Yankumi for advice and support, and their relationship develops in a unique way throughout the fanfiction.
Judy Hopps would be a great choice. She's a strong and determined character. Her pregnancy could bring out a different side of her, showing her vulnerability and also her ability to adapt. It could also create interesting storylines with her partner Nick Wilde, as they navigate this new phase of their relationship.
Frankie Stein could be a great main character. Since she's always learning about the world and herself, a pregnancy could be a whole new adventure for her. She might be curious about how her body, which is made up of different parts, will handle pregnancy. And she could bring her unique perspective and positive attitude to the situation.
Sakura would be a great choice. She's a strong and independent female character. Her skills as a medical ninja would add an interesting dimension to a pregnancy story. She could use her medical knowledge to take care of herself during pregnancy and also be a role model for other pregnant women in the village.
One idea could be a character facing the challenges of an unexpected pregnancy while dealing with family drama in Hollyoaks. Maybe she has to hide it from strict parents at first.
Timmy could be a great main character in such a fanfiction. If his mother was pregnant, he could have all sorts of adventures with his fairies as he tries to deal with the upcoming changes in his family.
Mandy could also be a likely candidate. Given her more carefree nature, a pregnancy would force her to grow up and face new responsibilities. It would be interesting to see how she copes with the changes in her body and the expectations that come with being pregnant.
It could be Dexter's teacher. If she got pregnant, it would add an interesting layer to the school environment in the Dexter Laboratory. The students, including Dexter, might be curious and try to understand what's going on. And she could be dealing with all the normal pregnancy stuff while also trying to teach her students, which could lead to some comical and heartwarming situations.
The Capitol could still be the main antagonists. They might see Katniss's pregnancy as a threat, either because they fear the child could grow up to be a symbol of resistance like Katniss or just because they want to maintain control over her. They could try to harm her or the baby in some way.
