One possible character is Ticci - Toby. His tic - filled personality and violent tendencies could be incorporated into the fanfic. There might also be Nurse Ann, who has a rather creepy and menacing presence. Additionally, Sally, the little girl with a tragic backstory in creepypasta, could be in the fanfic. She could interact with Bella in ways that either help or hinder her in the world of creepypasta.
There could be classic creepypasta characters like Slenderman. He is a well - known figure in the creepypasta universe, often associated with mystery and fear. Another possible character could be Jeff the Killer. His creepy appearance and murderous nature would add a lot of horror to the fanfic. There might also be characters like Eyeless Jack, who has his own unique and disturbing backstory.
There could be Edward. Even though the focus is on Carlisle and Bella, Edward's presence might still be felt as he was an important part of Bella's life before. His reactions to Carlisle and Bella's relationship could add some drama.
Often, you'll see Edward in these fanfictions. Even though the story is about Bella as a vampire before Twilight, Edward still plays a role. Maybe he's a mystery to Bella at first, or he's from a different vampire group that she has to interact with. Another common character is Jacob. He could be in a more antagonistic role, being jealous of Bella's new vampire life. And of course, the Cullens might be mentioned or even play a part. Carlisle could be a figure that Bella looks up to for advice on being a 'good' vampire.
Alice could be a great addition. She could use her ability to foresee events to help Edward and Bella avoid getting caught by the police. Another good character would be Carlisle. He could be the voice of reason, trying to convince Edward to turn away from his criminal ways. Jasper might also be included, perhaps using his power to influence emotions to help in certain situations.
Edward, of course. He's Bella's main love interest in the Twilight series, so it's very likely he'll be by her side in the hospital. He would be the one to comfort her, and his vampire abilities might come in handy, like his super - speed to get things she needs quickly.
Alice is often a very popular character. Her ability to see the future can add an interesting element to the wedding planning. For instance, she might foresee some problem with the wedding dress or the weather on the big day and try to prevent it. Jacob also makes an appearance in some fanfictions. His presence can create some tension as he still has feelings for Bella.
Alice could be a great addition. She could be Bella's best friend who is always trying to play matchmaker between Bella and Jasper. She has this uncanny ability to sense when things are going well or not so well between them and gives her two cents whether they want it or not.
Since I haven't read the fanfiction, I can't say for sure. But it's possible that there could be new characters introduced to either support or oppose this strange relationship between Bella as Jasper's pet. Or perhaps some existing characters from the original story might have different roles or personalities to adapt to this new situation.
One possible main character is Alice. She has the ability to see the future, which could be crucial in the plot of the fanfiction. For example, she might foresee something related to Bella and the vampires. Then there's Jasper, with his power to manipulate emotions. His character could add depth to the story, especially in relation to how the vampires interact with Bella and each other. Also, Esme could be a main character. As a mother figure in the vampire family, she could have an influence on Bella's experiences within the vampire world.
Jacob could be a great addition. He has a complex relationship with Bella in the original series. In fanfiction, his interactions with Charlie could be explored further. For example, how Charlie reacts to Jacob's wolf - shape - shifting abilities and his love for Bella.
In addition to Bella, her family members are likely to be part of the story. Her mother could be a source of both wisdom and worry, while her father might be more reserved in his reactions. There could be a neighbor who has had children of her own and offers Bella some much - needed advice. And don't forget about the baby! Even though it's just been born, it can be a character in its own right, with its own needs and presence that affects the story.
