Since Bella is already a vampire, her character development could focus more on her coming to terms with her new existence in a different way. She might not have the same initial struggles with bloodlust as she does in the books. Instead, she could be more interested in exploring the vampire culture and history right away. This would lead her to interact with different vampires, not just the Cullens, and gain a broader understanding of their world. This, in turn, would shape her character into a more worldly and independent vampire.
In the original, Bella is more of a damsel in distress. But as an assassin in fanfiction, she becomes more independent and self - reliant. She no longer waits for others to save her but takes matters into her own hands.
She might be more assertive. Since she is related to Klaus, she may inherit some of his confidence. So instead of being the meek Bella we know from the original, she could be more outspoken and take charge of situations.
Bella's character often becomes more confident. As a vampire, she has newfound strength and abilities that make her less timid. For example, she may be more assertive in her relationships and in dealing with threats.
Bella's character might become more confident. Without Edward, she has to rely on herself, which forces her to grow. As a vampire, she'll be more physically capable, and this could translate into mental strength as well.
In some fanfics, a possible plot twist is that Bella, as a vampire, has a different sire than Edward. This could lead to a whole new set of alliances and rivalries. Maybe her new sire has a dark past or is part of a vampire clan that is at odds with the Cullens. This would force Bella to re - evaluate her loyalty and her place in the vampire world.
Bella may become a more adventurous character. Maybe she decides to try new things that she was always too afraid to do before because Edward was so overprotective. She could start going to parties, trying extreme sports, or exploring new hobbies. This new adventurous side of her would make her a more well - rounded character, and when Edward returns, he would see a completely different Bella.
In such a fanfiction, it could change the entire dynamic of Bella's relationship with the other characters. Maybe she'd be more confident and powerful from the start.
The development of their relationship in fanfics can be quite complex. Some fanfics might show Jasper using his gift to calm Bella's nerves, which then becomes a way for them to get closer. As they interact more, Bella may start to see Jasper in a new light, not just as a member of the Cullen family but as a potential love interest. Their relationship might also be affected by the events in the Twilight world, such as battles with other vampires. These events can either bring them closer together as they rely on each other for support or create new tensions. But overall, in these fanfics, the relationship between Bella and Jasper often evolves from a simple attraction to a multi - faceted and passionate connection.
One popular 'Bella is already a vampire' Twilight fanfiction is 'The New Life of Bella Swan'. It takes the concept and explores how Bella's relationships change when she's already a vampire from the start. Another is 'Bella's Vampire Beginnings' which delves into her early days as a vampire, her new powers and how she copes with the vampire lifestyle.
One unique element could be the different power dynamics. Since Bella is already a vampire, she doesn't have the same vulnerability as in the original story. For example, her relationship with Edward might not be as protective - based. Another element is how she fits into the vampire society right away. In the normal story, she has to be gradually introduced, but here she's already part of it, so it might change the way other vampires view and interact with her.
