A possible plot for Harry Potter x Bella Swan fanfiction is that there is a spell gone wrong that pulls Bella into the world of Harry Potter. At Hogwarts, she stands out not only because she's new but also because she has this strange allure that comes from her Twilight - based self. Harry is intrigued by her and decides to help her adjust. As they explore the wizarding world together, they discover that there are similarities between the two worlds. For example, the idea of a chosen one in the Harry Potter world is somewhat like Bella's role in the Twilight series. They could then use these similarities to their advantage when facing challenges, like an ancient evil that wants to merge the two worlds for its own dark purposes.

Or perhaps Bella's vampire - like qualities in her own world are seen as a form of magic in the wizarding world, and she has to learn to control it with Harry's help.

Maybe there's a prophecy that involves both of them, and they must fulfill it to save both the wizarding world and Forks.
