Love against all odds is also a big theme. Since they are from different fictional universes originally, their relationship is considered taboo or at least very difficult. Fanfictions often explore how their love can overcome these barriers. For example, in some stories, they have to battle powerful enemies who don't want them to be together. And in the process, their love becomes stronger. This is a very engaging aspect for readers as it shows the power of love in a very dramatic way.
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.
There's also 'Mates Across Realms'. This fanfiction delves deep into how their different worlds, Bella from the Twilight world and Klaus from The Vampire Diaries world, come together. It has a great plot that builds their relationship gradually. The author does an amazing job of creating scenarios where they have to rely on each other and in the process, fall in love.
Family interference is often a theme. Their respective families might not be too happy about their relationship. For Bella, the Cullens might have concerns, and for Rebekah, her Mikaelson siblings could have opinions. This can lead to conflict and drama in the fanfiction. Also, self - discovery is a theme as they both learn more about themselves through their relationship with each other.
One common theme is the exploration of power dynamics. Bella, coming from the 'Twilight' world where vampires have different powers, and the Mikaelsons who are powerful in their own right in 'The Originals'. Another theme could be family. The Mikaelsons are all about family loyalty and drama, and Bella has her own family issues in 'Twilight'. So, fanfictions might explore how these two aspects of family interact. Also, there's often the theme of love and attraction, whether it's a new love interest for Bella within the Mikaelson family or some sort of forbidden love scenario.
One common theme is the clash of their two different vampire worlds. Finn's more traditional vampire lore from 'The Originals' and Bella's Twilight - style vampires can make for an interesting contrast.
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.
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.
Sure. AO3 (Archive of Our Own) is also a great place to look for such fanfiction. Writers might delve into how Bella and Rebekah's personalities interact. Bella is often portrayed as a bit more reserved and Rebekah as more fierce. Their relationship as mates could bring out new sides of both characters, like Bella becoming more assertive and Rebekah more protective. There could be a lot of character development in these stories.
There could be a fanfiction where Bella, after the events in her own series, somehow ends up in the world of Klaus Mikaelson. She might initially be scared, but her strong will makes her stand up to Klaus. And as time passes, they start to see each other in a different light. Maybe she helps him deal with his family issues, while he protects her from the new threats in his world.
Well, there are fanfictions that play with the idea of Bella's mind - reading ability (if it was more developed) and how it would interact with Klaus's complex and often secretive mind. It could lead to some intense mental battles and also a deep understanding between them. Some stories might also explore a romantic relationship where Klaus, who is used to power and control, has to learn to be vulnerable around Bella. And vice versa, Bella has to adapt to Klaus's more brutal and ancient ways of dealing with things. They could face challenges from both their own 'families' in the respective fictional worlds, like the Cullens being wary of Klaus's intentions towards Bella and Klaus's siblings having their own opinions about his newfound interest.
