Her relationships would be greatly altered. For example, her friendship with Angela and other human friends would become strained. She would have to keep her new identity a secret from them to protect them. The Cullens as a whole would have to re - evaluate their relationship with her. Carlisle might try to study her new powers, while Rosalie could be jealous or resentful of the attention Bella gets due to her unique transformation. Emmett might be more intrigued and want to see what she can do. Alice could try to predict how Bella's new powers will affect the future of the family.
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.
Well, Bella's relationship with Edward would have new challenges. He's a vampire and she's now a banshee. Their different natures could lead to conflicts. For instance, the banshee's connection to death and premonitions might make Edward worry more about her safety and sanity. With the werewolves, her relationship with them could be more complex. Jacob might feel a sense of competition as Bella now has a powerful identity of her own. And in general, her relationships within the Forks community would be in turmoil as she tries to balance her human past and her new banshee self, all while dealing with the reactions of those around her.
With Edward, their relationship would be different. They'd be more equal in terms of strength and power. No longer would Edward need to constantly protect Bella. Instead, they could fight side by side against their enemies. Their relationship might also have a new dynamic of competition, as they both explore their new vampiric abilities.
One possible plot could be that Bella discovers her new banshee powers after some strange and traumatic event. Maybe she starts having premonitions not just about danger to herself like in the original Twilight series, but about disasters that will befall the entire town. This could put her in a position where she has to figure out how to control these powers and also how to convince others, like the Cullens, that she's not going crazy.
At first, their relationship might become strained. Bella's sister would have to keep her new identity a secret from Bella, which could create distance. But once Bella finds out, they could become closer as Bella tries to understand what her sister is going through. Bella might be more protective of her sister now that she's in a more dangerous world.
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.
Her relationship with Edward would likely become more equal. As a human, Bella was often in a more vulnerable position, but as a vampire who has flipped her switch, she could stand on equal footing with him. They might engage in more intense and equal - sided battles or hunts together.
When Bella has a power like super strength in fanfiction, it can change how others view her. Her friends might be in awe of her new ability, but it could also make some of them feel inferior or intimidated. Her relationship with Edward might also change as he has to adjust to not always being the one to protect her. He might feel a bit of jealousy or pride in her newfound strength.
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.
Romantically, if Hermione becomes a boy, she might attract different people. Maybe some of the female students who were just friends with her before start to have a crush on her. And she would have to figure out how to handle these new romantic interests while still being true to herself and her old friendships.
Her relationship with Edward would definitely change. Edward is used to a more innocent and reserved Bella. If she becomes a Katherine Pierce fan, she might become more assertive and independent, which could either make Edward more attracted to her in a new way or cause him to be wary. He might not like the new, more dangerous side of Bella that is emerging.
