In some fanfictions, her transformation into a white werewolf might lead to a war between different supernatural factions. The vampires might see her as a threat, thinking she could lead the werewolves to become more powerful. Meanwhile, within the werewolf pack, there could be those who oppose her because of her former ties to the vampires. Her journey to find her place in this new world full of conflict and power struggles would be an interesting plot point.
One possible fanfiction could be about Bella's transformation being a result of a unique genetic mutation in the werewolf bloodline. In this story, she might struggle to come to terms with her new form and the powers that come with it. Maybe she has to hide it from her friends at first, especially Edward and the Cullens, as they are vampires and there could be an inherent distrust between the two species in this fan - made universe.
Often, one interesting plot point is how Bella acquires the knowledge or power to turn Edward. Maybe she discovers an ancient spell or some new vampire lore. Another point could be Edward's initial reaction. He might be shocked, angry, or even a bit excited at the prospect of a new existence.
In some fanfiction, if Bella turns into a werewolf, it could completely change the dynamics of the story. For example, her relationship with Edward would be put to the test. Werewolves and vampires are natural enemies in the Twilight universe. Edward might struggle with his feelings for her, seeing her as a 'monster' in the eyes of his kind. And Bella herself would have to adapt to new instincts and a new identity. She'd no longer be the vulnerable human, but a powerful werewolf with her own set of rules and abilities within the pack.
Well, in some fanfictions, Bella Swan discovers she has a long - lost wizard relative. This connection then leads her to Hogwarts. Her struggle to fit in both in the wizarding world and with her own vampire - related issues in the Twilight world can be a great plot point. And the idea of a wizard - vampire hybrid that Bella might become due to some magical accident in the wizarding world is also really cool. It would completely change the power dynamics and relationships in both universes.
There's also 'Bella and the Werewolf Guardians'. This fanfiction might focus on the werewolves protecting Bella from various threats in a more elaborate way. They could have special powers or a unique connection to Bella that wasn't as emphasized in the original. It may also delve into how Bella's presence affects the werewolf pack's dynamics, like bringing about new alliances or rivalries within the pack.
In many such fanfictions, a key plot point could be the internal struggle Carlisle faces. He is a moral vampire, so turning Bella goes against his principles at first. He might worry about how Bella will adapt to the vampire life, with its bloodlust and the need to hide from humans. Another plot point could be Bella's reaction. She may be initially excited at the prospect of immortality and being with Edward forever, but then realizes the sacrifices she has to make, like leaving her human family behind.
One popular 'Aro turns Bella' fanfiction might be 'Aro's New Coven Member'. In this type of fanfiction, it often explores a different path for Bella where she is turned by Aro instead of Edward. It could involve Bella having to adapt to the Volturi way of life, dealing with their rules and politics. Another could be 'Bella under Aro's Influence', which might focus on how Bella's relationships with the other characters, like the Cullens, change when she becomes part of Aro's world.
Well, one interesting plot point could be the relationship between Lyla and Derek. Maybe they have to overcome some sort of werewolf - related challenges together, like dealing with rival packs or some ancient werewolf curse.
Another plot point could be Anikin's relationships. Her relationships with her master and other Jedi might change drastically. They may view her differently or she may develop new emotional connections with other characters. And there could be a sub - plot about her exploring her new gender identity and how it affects her connection to the Force.
One interesting plot point could be how Bella adapts to Jasper's military - like discipline. Since Jasper has a background of being in the Confederate Army, his sense of order and discipline might be new to Bella. Another plot point could be how they deal with the other Cullens' reactions. Some might be supportive, while others could be skeptical at first. Also, the way they combine their different personalities. Bella's more impulsive nature and Jasper's more reserved one could lead to some really interesting character - driven plotlines.
