A school bully might be a character. This bully could pick on Bella because of her braces, making fun of how she looks. But then, as Bella becomes more confident, the bully's taunts have less of an impact. Another possible character could be a love interest. He could initially be a bit put off by the braces but then realize that Bella's personality is what really matters and start to like her more.
There could be her parents. They might play a role in encouraging her to get braces or helping her take care of them. For example, they could remind her to brush her teeth properly with braces.
Edward is almost always there. Since he's such a central figure in Bella's life as a human and vampire in the original story, he would likely play a big role in the fanfiction too. He might be the one guiding Bella through her new vampire life.
There could be the doctor who is performing the pelvic exam. This doctor might be an experienced and empathetic person.
Maybe it could be about Bella's journey of getting used to having braces. For example, she might initially feel self - conscious, but then she discovers new confidence as she sees the positive changes in her teeth over time.
There could be Edward. Even if Bella is now immortal, Edward might still play a significant role. He could be either her eternal love or her adversary depending on how the fanfiction is written. Another character could be Alice. Since Alice has her own special abilities, she might be there to help Bella navigate the new world of immortality. For example, she could foresee some of the challenges that Bella will face. Also, Jacob might be a main character. His relationship with Bella, whether it's a friendship or something more complicated, could be further explored in the context of Bella's immortality.
There could be Edward. Maybe he is involved in Bella's life with her psychic powers. He might be curious about her abilities or even try to protect her from the consequences of using those powers.
There could be her drill sergeant. This person would be tough and no - nonsense, pushing Bella to her limits during training. Another character might be her best friend in the air force, someone who is always there to support her, through the good times and the bad. There could also be a rival, someone who is constantly competing with Bella for promotions or recognition.
Well, it could be the people she targets. They would be important as they drive the action when Bella is on her 'killer missions'.
Perhaps there are characters from outside the pack that also play a role. Enemies of the pack could be main characters as they pose a threat to Bella and the pack. This would give Bella the opportunity to show her protective side as the pack mother. Or there could be some neutral characters who get involved in the pack's affairs because of Bella's new role and end up being important to the story.
Edward could be one of the characters. He might be in a love - hate relationship with Bella due to her addiction. He could be torn between his love for her and his inability to stand her self - destructive behavior.
Foster parents are likely to be important characters. They could be kind and nurturing, or perhaps they have their own issues that create more drama for Bella.
