Maybe a time - travel fanfiction. Bella somehow gets sent back in time and ends up in the era when the Mikaelsons were first created. She meets Elijah and they have a series of adventures. Elijah is intrigued by this strange girl from the future and tries to protect her while also using her knowledge to change some of the fates of his family members for the better.
One idea could be a story where Bella discovers the world of the Mikaelsons after being turned into a vampire. She crosses paths with Elijah and they form an unlikely alliance to deal with a common threat in the supernatural world. They learn from each other's experiences, with Bella's knowledge of the Volturi and Elijah's centuries - old wisdom.
Research is key. Look into the 'Twilight' series to fully understand Bella's world and the 'The Vampire Diaries' / 'The Originals' universe for Elijah. When writing their relationship, start slow. Maybe they start as reluctant allies. As for the story's setting, you could choose a new location that combines elements of both their worlds, like a small town that has a hidden vampire coven and is also on the verge of being invaded by an ancient evil that only they can stop together. You can also add some secondary characters from both franchises to add more depth to the story.
Sure. Fanfiction.net also has some interesting ones. It really depends on what you're looking for in their relationship. If you like angsty stories, there are those where they struggle against their different loyalties - Bella to the Cullens and Elijah to his family. And if you prefer more romantic, light - hearted tales, you can find ones that focus on their courtship and how they discover they are mates.
One common theme is the clash of their two different vampire worlds. Bella is from the Twilight world with its own set of vampire rules, and Elijah is from The Vampire Diaries universe with different lore. Another theme is the struggle for acceptance within their respective families and communities. Since they are mates, they have to find a way to make their relationship work despite potential opposition.
A fanfiction could also be about a time - traveling scenario. Elijah Mikaelson travels back in time to the era of the founders of Hogwarts. He gets involved in the early magical society and later crosses paths with a young ancestor of Harry Potter. Their interactions shape the future of both the wizarding world and the Mikaelson family in some unexpected ways.
One idea could be a crossover where Elijah Mikaelson ends up in the wizarding world of Harry Potter. Maybe he's there to seek a powerful magical artifact that could help him in his vampire family's never - ending power struggles. He might initially be seen as a threat by the Ministry of Magic but then prove himself useful in the fight against dark wizards.
A really interesting storyline could be Bella trying to reconcile her old life in Forks with her new life as a Mikaelson. She might struggle with the differences in values and lifestyles. For example, the Mikaelsons are more into power plays and manipulation in the supernatural world, while Bella was used to the more straightforward (although still complex) relationships in 'Twilight'. This internal conflict could be a major part of the story, along with her trying to find her place within the Mikaelson family and the wider supernatural community.
There is some. However, the quality can vary greatly. Some might focus on a romantic relationship between them, while others could be more about a friendship or an adventure they go on together. It really depends on what you're interested in. You might have to sift through a few to find the ones that really appeal to you.
One plot idea could be Bella's struggle to adapt to the Mikaelson family's vampire - werewolf drama while also dealing with her own newfound vampire - like powers as part of the family. Another could be her relationship with Klaus. Maybe she tries to temper his more violent tendencies and in the process, they form a unique bond that changes the family dynamics.
Klaus would probably be very intrigued by Bella. He's used to getting his way with most people, but Bella is not easily swayed. So he might start by trying to charm her, but she would be resistant. For example, he could offer her power or protection, but she would be more concerned about her own values and the people she cares about in Forks.
Well, if Bella Swan is a Mikaelson in fanfiction, it could lead to some really interesting character developments. Maybe she inherits the Mikaelson's power and has to learn how to control it. It also might change her relationships. For example, her relationships with the Cullens in 'Twilight' would be completely different as she now has a connection to the Mikaelsons. This could create a whole new set of conflicts and alliances.
