Bella is the central character for sure. Then there's Edward. Their relationship will likely change in many ways now that Bella is a vampire. Alice might also be a main character. With her ability to see the future, she could help Bella understand and navigate her new life. Jasper too could be important as he has experience with controlling his vampire instincts, which Bella will need to learn.
Obviously, Bella is a main character as the title implies she is the one becoming a vampire. The Cullen family members are also likely to be main characters. Edward, who was in a relationship with Bella when she was human, will surely play an important role. Also, Carlisle, the patriarch of the Cullen family, might be involved in guiding Bella through her new vampire existence.
The main character is Bella, who is at the heart of this fanfic's transformation. But we can't forget about Jacob. Even though he was on the werewolf side, his relationship with Bella was complex. His reaction to Bella becoming a vampire could be an interesting part of the story. And of course, the other Cullen family members like Rosalie and Emmett will also be main characters as they are part of Bella's new vampire family.
Bella is the central figure in these fanfics. Then, there could be new characters created specifically for the fanfic. But in terms of the original series, Edward is bound to be there. He'll have to adapt to Bella's new status. Also, Jacob might still be in the picture, perhaps having a more complicated relationship with vampire Bella. And of course, the other Cullens, who will be her family in the vampire world, are main characters as well.
Edward would still be a very important character. Since he's Bella's love interest in the original 'Twilight' series, in the fanfiction, he would play a major role in Bella's new vampire life. He might help her adjust to her new powers and the vampire lifestyle.
Well, Bella is obviously one of the main characters. She is often the central focus, with her relationship with vampires being the main plot point. Edward is also commonly a main character, as in the original Twilight series, their relationship is a big part of the story. Jacob sometimes makes an appearance too, adding an element of conflict or friendship, depending on the direction of the fanfic.
Jacob could also be a common character. Even though Bella has become a vampire, her past connection with Jacob and the werewolf pack might still play a role. There could be some tension or new interactions between the vampires and the werewolves. And of course, Carlisle, as the head of the Cullen family, is likely to be in many of these stories to guide Bella in her new vampire life.
The main characters are Edward and Bella, of course. Edward is the vampire who falls in love with Bella, a human girl at first. Bella is attracted to Edward's mysterious nature. Their relationship is the central focus of the fanfic.
There could be a vampire hunter who is after Alvin. This hunter might be an old acquaintance who now sees Alvin as a threat.
Well, Bella is obviously one of the main characters. Since it's about her being born a vampire, she will be central to the story. There might also be other vampires that she interacts with, like the Cullens if it follows the Twilight universe to some extent.
Her parents might be important characters. They could either be supportive of her career choice or initially be against it, thinking it's too difficult. Also, there could be a senior lawyer at the firm where she interns, who takes her under his or her wing and guides her through the complex world of law.
Well, a plotline could be Bella's reaction to no longer being able to eat human food. She might miss the taste of her favorite dishes and have to deal with the cravings for blood instead. Also, there could be a plot where she discovers new vampire powers that are unique to her. This could lead to her being both feared and respected among other vampires.
Perhaps some of the other Cullen family members would be her allies. They are already vampires and could help her adjust to her new powers and the vampire lifestyle. For instance, Alice might use her power of seeing the future to guide Bella in making important decisions. Jasper could teach her how to control her new vampire instincts, like the urge to hunt. And Emmett could be her sparring partner to help her improve her combat skills.
