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.
Jealousy could also play a part. If the Mikealson daughter has something that Bella desires, whether it's the love of a certain character, a special ability, or a high social status within the fictional world. This jealousy could drive Bella to take such a drastic step as killing her in the fanfiction.
Power might be a motivation. If in the fanfiction universe, killing the Mikealson daughter gives Bella some sort of power or advantage. It could be a power that is unique to the world - building of that particular fanfic, like access to a special magic or a position of authority within a certain group.
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.
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.
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.
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 motivation could be his love for Bella. In the Twilight series, Edward is deeply in love with Bella. Maybe in this fanfiction, he kidnaps her out of an extreme form of protecting her. He might see some impending danger that Bella is unaware of, and he believes that by taking her away, he can keep her safe from harm.
Well, it could be about Bella having some sort of special relationship with a tiger. Maybe she has the ability to communicate with it on a deeper level, like they share a telepathic bond. And she might go on adventures with the tiger, protecting the forest or something.
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.
Well, it could involve Bella having special powers from being Poseidon's daughter. Maybe she can control water to protect Forks from some new supernatural threats. She might also have a connection to the ocean that draws her away from the normal vampire - human drama in the original 'Twilight' story.
Well, it could be a story about family secrets. Maybe Bella has just discovered that Billy is her father and she has to deal with the shock of this new information while also getting to know Billy and his side of the family.
In a 'bella is thor's daughter fanfiction', the plot could involve Bella being whisked away to Asgard. There, she has to learn about her father Thor and the ways of the Asgardians. She might get into trouble with the other Asgardians who are skeptical of her because she's from a different place. But as she proves herself, she could form alliances and help Thor in some great battle or quest, all while coming to terms with her new identity.
