Who are the main characters in 'Twilight Bella becomes a vampire fanfiction' other than Bella?

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.

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.

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.

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.

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.

Bella herself is obviously a main character. And then, depending on the direction of the fanfiction, it could be a new character created by the author. This new character could be the one focused on saving Bella. There might also be appearances from the original Twilight characters like Edward or Jacob, but they could have different roles compared to the original story.

Obviously, Bella is one of the main characters as the title includes her name. And then there's the billionaire character. Since it's a Twilight fanfiction, other characters from the original Twilight series might also make appearances or be referenced, like Edward or Jacob, who could potentially influence the relationship between Bella and the billionaire in some way.

The truck itself could be considered a main character in a sense. It has its own presence and significance in the story.

There could be characters from the original stories that Bella and Jane come from. For Bella, characters like Edward or Jacob might still play a role, perhaps in the form of her past relationships that now create some sort of complication in her new relationship with Jane. From Jane's side, other Volturi members could be involved, like Aro or Caius, who might have opinions on Jane's new mate.

One interesting plot twist could be that Bella, as a new vampire, discovers she has unique powers that no other vampires have. For example, she might be able to control the elements in some way.
