Well, perhaps the story could be about Kol's twin as Bella Swan trying to find a way back to her own world. Along the way, she has to navigate the complex relationships in Forks. She might befriend some of the characters like Alice in a different way, sharing with her some of the prophetic knowledge she has from her Mikaelson heritage. And when it comes to the werewolves, she could have a more diplomatic approach compared to Bella, due to her experience dealing with different supernatural factions in her own world.
One possible plot could be that Kol's twin sister, being a vampire in the Twilight universe as Bella Swan. She might be intrigued by Bella's relationship with the Cullens. Maybe she tries to interfere in their relationship out of jealousy or a desire to understand human - vampire love better. Since she has her own vampire powers from the Mikaelson lineage, it could create some interesting conflicts with the vampires in Forks.
If Kol's twin was in Bella's body, her personality would likely change the story a great deal. Kol's twin would probably be more assertive and less passive than Bella. She might not put up with Edward's over - protectiveness in the same way and would be more likely to go off on her own adventures. This could lead to her getting into more dangerous situations or uncovering secrets faster.
When it comes to the other Cullens, like Alice, Kol's sister could be both intrigued and a bit dismissive. Alice's visions might seem like a novelty to her at first, but then she could start to resent them if they interfere with her own plans. And with Jacob, she might be amused by his werewolf nature. She could see him as a more natural predator compared to the 'tame' vampires of the Cullens. Overall, her interactions would be a mix of curiosity, rivalry, and in some cases, friendship.
One possible plot twist could be that Bella, as a Mikaelson twin, discovers a hidden power within herself that is different from the other Mikaelsons. Maybe she has a unique connection to nature, like being able to control certain elements. Another twist could be that she is actually a key to an ancient prophecy that the Mikaelson family has been trying to figure out for centuries. This would put her in a central position in the family's power struggles and relationships. And perhaps she finds out that she was switched at birth and her real family is someone completely different, which would create a whole new set of conflicts and emotional turmoil within the story.
As a Mikaelson twin, Bella would likely become more assertive. In the Twilight series, Bella was often more passive, but in the Mikaelson world, she'd need to be tough. She'd have to learn to use her newfound powers quickly. Also, her relationships would change. Instead of being focused on Edward or Jacob, she'd be dealing with the complex family dynamics of the Mikaelsons. Her sense of loyalty would expand to include her new family, and she might become more calculating in her actions to protect them.
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.
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.
Yes, there are likely fanfictions out there with this concept. Fanfiction writers often come up with unique crossovers, and the idea of Bella Swan from 'Twilight' being Elsa's twin sister is a creative and out - of - the - box concept that could be explored in fan - created stories.
