Besides Bella, including Renesmee in the fanfic can be interesting. Even though she's the result of the pregnancy, her presence can change the story in many ways. For example, how she interacts with her parents as a child. Also, the Volturi members like Aro could be included. Their interest in the unique pregnancy could create a lot of tension and conflict in the story.
Alice would be a great addition. With her ability to see the future, she could predict things about the baby or any potential threats during the pregnancy. Rosalie might also be included. Given her past desires for a child, she could have a unique perspective on Bella's pregnancy. And of course, Esme. She could provide a motherly figure for Bella during this difficult time.
Edward is an obvious choice. As the father of the baby, his role is crucial. He can be portrayed as overprotective, or struggling to understand the new situation. Jacob could also be included. His relationship with Bella is complex, and his reaction to her pregnancy could add a lot of drama. Then there's Carlisle. As a doctor - like figure in the vampire world, he can offer medical advice and support during the pregnancy.
Alice Cullen can be a very popular character. Since she can see the future, in a 'reborn as bella swan' scenario, her interactions with Bella could be really different. Maybe she tries to guide Bella in a new way based on her visions. Also, Carlisle Cullen is popular. His father - figure role towards Bella might be explored further in these fanfictions.
Edward Cullen would likely be a main character. His reaction to Bella's situation, whether it's concern for her well - being or struggle with his vampiric instincts around her period blood, could be a major part of the story.
Edward is still very popular. Since he and Bella are now both vampires, their relationship takes on new aspects that fans like to explore. Another popular character is Alice. Her ability to see the future could be really interesting in a story where Bella is a vampire. She could foresee events that involve Bella and help her avoid danger or make important decisions.
Edward Cullen is often a popular character in these fanfictions. Since he has a close relationship with Bella in the original story, his role can be further explored in relation to Rosalie and Bella's relationship. Another one could be Alice Cullen. Her ability to see the future can add an interesting dynamic, especially when it comes to predicting things that might affect Rosalie and Bella's friendship or any adventures they might go on.
It really depends on the specific fanfic. There could be her husband, who would be a central character as well. He might be the one that Bella is trying to be the perfect wife for. There could also be friends or family members. Maybe a nosy neighbor who adds some comedic relief or a mother - in - law who has high expectations of Bella. In some cases, there could be a rival character, someone who is jealous of Bella's relationship or her status as the perfect wife.
The main characters are Bella Swan and Klaus. However, depending on the specific fanfiction, other characters could also be prominent. For example, Jacob might be involved, as he has a history with Bella. He could have strong reactions to Bella's pregnancy by Klaus. Also, characters like Elijah from Klaus's family might make an appearance and add more complexity to the story, perhaps trying to influence Klaus's actions regarding Bella and the unborn child.
Alice is often a great character in such fanfiction. Her ability to see the future can add a lot of twists and turns to the story. For example, she might foresee a danger to Edward and Bella's relationship and try to prevent it.
One of the main characters could be a villainous vampire. This vampire could be after the sisters for some reason, like their unique powers or because they pose a threat to his own plans in the vampire world. Also, Bella's father Charlie could be a significant character. He might start to suspect that something is different about Bella and her sister, and his reactions and attempts to figure out the truth could be an important part of the story.
Since it's a fanfic, it might introduce new characters that are unique to this story. There could be a rival within the federal system who is jealous of Bella's new - found status with the badge. Or perhaps there's a mentor - like figure who has been in the federal service for a long time and helps Bella understand the ropes. Another possibility is that there are informants that Bella has to deal with. These informants could be from different backgrounds and have their own motives for helping or hindering Bella in her work with the badge.
Edward could be one of her allies. He could use his vampire abilities such as super - speed and strength to assist Bella in dangerous situations. His centuries - old knowledge could also prove invaluable in understanding the motives and actions of the CIA's enemies. Another ally could be Jacob. His shape - shifting abilities would give the team an extra edge in combat or in covert operations. He could also use his connection to the werewolf pack to gather information from areas that the CIA might not have easy access to.
