She would likely be more confident. Knowing she has a divine connection would give her a sense of purpose and self - assurance that she doesn't have as a normal human in the original story. She might also be more selfless, as she would be influenced by the idea of her divine father's love and teachings. This could make her more willing to sacrifice for others.
She would be more confident. Since she's the daughter of a powerful god, she would have a sense of self - worth that might not have been as strong in the original story. She'd also be more assertive, using her powers to protect herself and others.
She would be much more confident. In the original Twilight, Bella is often insecure, but as Zeus's daughter, she would know she has divine powers and a powerful lineage. So she'd be more self - assured.
She would likely become more confident. Knowing she is the daughter of Hades, a powerful god, would give her a sense of self - worth that she might not have had before. For example, instead of being the damsel in distress in her relationship with Edward, she could be an equal partner, using her powers to protect him and his family if needed.
If Bella becomes a banshee, her relationship with Edward would be very different. He would be more protective of her as she has a new and potentially dangerous power. He might also be a bit wary as banshees are known for their wailing which could attract unwanted attention. With Jacob, he might see her as even more of an enigma and be more drawn to her in a way, since she's now a more powerful supernatural being.
She would likely become more confident in her own strangeness. Instead of being the somewhat shy and self - deprecating Bella we know from the Twilight series, she would embrace her darker side. For example, she might not be as hesitant to stand up to those who try to bully or intimidate her.
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 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.
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.
The story would likely have more action. Bella would be involved in more combat and stealth situations.
