One plot idea could be Bella struggling to choose between her vampire life with Edward and her deep friendship with Jacob that has the potential to turn into more. Another could be Jacob trying to protect Bella from a new vampire threat while also dealing with his feelings for her. Maybe a plot where Bella discovers a new power as a vampire that Jacob has to come to terms with.
A possible plot could be that Bella, as a vampire, starts to have visions of the future that involve Jacob. These visions show different paths their relationship could take, and they have to figure out if they should follow the visions or not. Also, there could be a story where Jacob is injured badly in a fight, and Bella has to use her vampire abilities to save him. This experience makes them realize how much they mean to each other and changes the dynamic of their relationship completely.
Well, a really interesting plot might be that Bella and Jacob find out they are soulmates in a different way than expected. This could cause a rift between Bella and the Cullens as they try to figure out how to handle this new situation. Or perhaps there's a plot where Jacob's wolf pack has to team up with the Cullens to fight a common enemy, and during this time, Bella and Jacob's relationship deepens in unexpected ways. They could start to understand each other on a whole new level.
One popular fanfiction could be about Bella's struggle between her vampire nature and her remaining feelings for Jacob. For example, a story where she tries to protect Jacob from the vampire world while still being drawn to him in a way that defies her new vampiric instincts.
Some fanfictions in this theme might focus on the reactions of the Cullen family. They could be either accepting or having some sort of conflict due to Bella's situation with Jacob. Also, the story could explore how Bella herself copes with the physical and emotional changes of being pregnant, especially in a world filled with vampires and werewolves.
I've read one where Bella discovers a new power as a vampire that allows her to communicate with Jacob telepathically. This completely changes the dynamic between them as they can now share their innermost thoughts and feelings without having to be in close proximity. It also makes their relationship more complex as they have to deal with this new form of connection.
Well, in fanfiction, Bella's character could be developed in a way that she explores her new vampire nature more deeply. She might be more curious about her powers and how they can be used in relation to Jacob. For example, she could discover that her vampire senses can help her understand Jacob's wolf side better. Jacob could be developed to be more empathetic towards Bella's vampire life. He might try to find common ground between his wolf pack and Bella's vampire world, which is a big shift from his initial hostility in the original story.
There is a fanfiction titled 'Bella's New Path with Jacob's Imprint'. This one delves deeper into how Bella copes with Jacob's imprint. It shows her internal struggle between her previous feelings for Edward and the new, intense bond with Jacob. It's a more emotional and character - driven story.
Well, a great plot might be that in a human - dominated world, Bella and Edward are trying to keep their true identities secret. But then, there's a series of mysterious disappearances in the town that they suspect are related to the supernatural. So they start to investigate together. Also, perhaps there's a prophecy in the supernatural world that involves a wolf - vampire - human bond, and they are unknowingly part of it. And this could lead to all sorts of adventures and challenges for them.
One great 'Bella Swan and Jacob Black Fanfiction' is 'The Wolf's Mate'. It delves deeper into their relationship outside of the main story, exploring Jacob's perspective more. Another good one could be 'Jacob's Redemption'. It shows how Jacob tries to win Bella back in a different way. And 'Bella's Choice' is also interesting as it presents a scenario where Bella has to make a tough decision between Jacob and her other life choices.
One idea could be that Bella discovers she has a special power that only she can use to protect the wolf pack. For example, she might be able to communicate with the spirits of the forest which give her warnings about upcoming threats.
One possible plot could be about the challenges of raising a baby in the world of Jacob and Bella. Maybe the baby has some special powers that they have to protect it from the wrong people.
Bella's actions in the fanfiction might be another cause. Maybe she accidentally says or does something that undermines Jacob's self - esteem. Like if she makes a comment about his werewolf nature in a negative way, it could wound him deeply as it's an important part of who he is.
