Yes, there might be. Fanfiction websites are filled with all sorts of creative and often dark or dramatic stories. You could try searching on major fanfiction platforms like Archive of Our Own or FanFiction.net. Just type in the relevant keywords and see what comes up.
It could be revenge. Maybe Bella has some sort of vendetta against the Mikealson family. Perhaps they did something to her or someone she loves in the past, and she sees the daughter as a way to get back at them.
Well, one possibility is that Bella's unique human nature attracts a Mikealson. Maybe her strong will, like in the original Twilight series, catches the eye of a Mikealson who is used to more submissive or less complex beings. They could start off as enemies, with the Mikealson initially seeing Bella as just another human to toy with, but then gradually fall for her unique charm.
Well, it depends on how popular the idea is within the fanfiction community. Some fanfic authors might be exploring this unique concept of Bella Swan being Bellathena Mikealson. You could also try joining relevant fan groups on social media platforms and ask for recommendations. There might be some hidden gems that haven't been widely discovered yet.
One possible plotline could be Bella Swan, now as Bellathena Mikealson, having to navigate the complex vampire - werewolf politics in a different way. Maybe she uses her new identity to bring about a truce between the two groups.
Bella's personality might become more assertive. Being around a Mikealson, who are often very dominant, she would need to hold her own. Instead of being the damsel in distress all the time, she could grow into a more self - reliant character. For example, she might learn how to fight better or use her wits in different ways.
I'm not sure as I haven't read that specific fanfiction. But generally in a fanfiction, Bella being the daughter of Trigntins would likely mean she has a special role within the story's universe created by the fanfic writer.
Sure. In the world of fanfiction, the idea of Bella being Voldemort's daughter is not unheard of. Fanfiction writers like to take existing characters and create new backstories or relationships for them. This particular concept could lead to all sorts of interesting plot twists. For example, it could change the dynamics between Bella and other characters in the Harry Potter universe, and also how she interacts with Voldemort. Maybe she could be a secret weapon or a source of redemption for him, or perhaps she could be a force of chaos in her own right.
She might have long, flowing golden hair like the sun, a symbol of her divine heritage from Zeus. Her eyes could be a bright, electric blue, reminiscent of Zeus' lightning. And she would probably have a tall and graceful stature, with a presence that commands attention.
There's also a possibility that some of the more morally grey characters in Gotham, like Catwoman, could be Bella's allies. Catwoman has her own code of ethics, and she might relate to Bella's struggle between good and evil. They could work together in certain situations, especially if there are mutual benefits involved.
