She may develop a deeper sense of empathy. Having to watch others age while she stays the same can make her more understanding of the transient nature of human life. This could lead her to be more protective of those around her, trying to make their short lives as good as possible.
Bella's character could also become more solitary. The experience of immortality can set her apart from others. She might start to withdraw from human society, only interacting with other immortals or those who understand her situation. This would be a big change from her more social and relationship - focused character in the original story.
In some fanfictions, Bella's character might become more confident. As an immortal, she no longer has the same fears of mortality. For example, she could be more fearless in facing dangerous situations.
She might become more assertive. As the daughter of Ares, she would inherit some of his war - like traits. So, instead of being the somewhat passive Bella in the original story, she could be more proactive in making decisions and taking action. For example, she may no longer wait for others to protect her but instead take the lead in dangerous situations.
She might become more protective. As Silas's sister, she would have a natural inclination to safeguard him, which could make her more assertive.
Bella could develop a stronger sense of survival. In the face of the mob's threat, she has to constantly be on the lookout for danger. This would make her more aware of her surroundings and better at finding ways to stay alive. For instance, she might learn how to hide, find safe places to stay, and avoid being detected. As she overcomes various challenges during her escape, she may also gain more confidence in her abilities. Initially, she might be very scared and unsure, but as she manages to evade the mob's pursuit, she realizes that she is capable of much more than she thought.
In princess fanfiction, Bella's character often becomes more assertive. For instance, as a princess, she has responsibilities and power. So, she may no longer be the meek girl from the original story. She might take charge in situations, like leading her people or making important political decisions.
In the fanfiction, Bella Swan as a fallen archangel may be seen as a more rebellious character. Her fall from grace could be seen as an act of defiance against the rules of the celestial realm. This new aspect of her character could lead to a whole new set of adventures and challenges, different from the love - triangle - centered plot of the original 'Twilight' series. She might be more focused on finding her place in the new world she has entered rather than just on her relationships with Edward and Jacob.
In an army fanfiction, Bella Swan's character would transform in many ways. Her self - confidence would grow exponentially. She was always a bit self - conscious in the original story, but in the military environment, she'd have to believe in herself to succeed. She'd also become more independent. No longer relying on others to protect her as much, she'd be trained to protect herself and her comrades. And her adaptability would improve, being able to adjust to different military bases, climates, and combat situations.
To develop Bella in this fanfiction, she could be given a mentor. Maybe an old witch who has been watching over her. With the mentor's help, she can learn about the history of doppelgangers in the witch world and how to control her powers. She can also struggle with the morality of using her powers, like whether she should use them to get revenge on those who have wronged her in the past.
She might be portrayed as a villain by showing her being manipulative. For example, she could use her relationship with other characters to get what she wants, like using Edward's love for her to control his actions or decisions.
Well, in some fanfictions, she might be depicted as the devil through her actions. Maybe she's shown as being manipulative, using her charm to get what she wants from others, much like how the devil is often portrayed as a tempter in traditional stories.
Bella Swan's character could be developed by having her explore different aspects of herself. In the context of Greek gods, she might discover a more passionate side of herself, like the passion associated with the Greek concept of eros. This could make her more confident and change her relationships. She could also be developed through her experiences with the Greek gods' powers. If she gets a taste of Athena's wisdom, she could use it to solve problems in Forks that she couldn't before. This would make her a more respected and important figure, not just among the Twilight characters but also among the Greek gods she encounters.
