One idea could be that the soulmate connection defies the natural enmity between the Twilight world and the Mikaelson's world. Maybe the soulmate bond allows them to communicate telepathically across different realms. For example, Caius could be in his vampire world in the Twilight universe while his soulmate is in the Mikaelson's world of witches and vampires, and they share dreams and thoughts that gradually bring them closer.
Over time, their relationship would also be shaped by the reactions of their respective families and communities. Caius' vampire coven in Twilight might be suspicious of his connection to a Mikaelson - related soulmate. And the Mikaelson family might have their own reservations. But as they stand up for each other against these external pressures, their bond becomes unbreakable.
She could fit in by bringing a new perspective. The Mikaelson world is often filled with violence and power - hungry characters. Hermione, with her values from the wizarding world like loyalty and friendship, could change the way some of the Mikaelsons think. Also, her magical abilities, although different from theirs, could be complementary. For instance, her skills in transfiguration might be useful in a situation where the Mikaelsons need to deceive their enemies. And she could also adapt to their world by learning about their unique brand of magic and culture over time.
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.
There's also a character named Sophia in some fanfictions. Sophia is written as very intelligent. She uses her wits to outsmart her family's enemies. She has a great relationship with her brothers, especially Klaus. They have a deep bond that is explored in the fanfiction, and she often helps him see reason when he's about to make a rash decision.
One great Klaus Mikaelson hurt fanfiction is 'Bleeding Hearts'. It shows Klaus in a really vulnerable state after a powerful spell backfires on him. Another is 'Broken Wings' where he gets physically injured during a fight with an ancient enemy and has to rely on his friends for help.
One idea could be a crossover with the Vampire Diaries. Hope could meet Elena and they could form an unlikely alliance against a new threat in Mystic Falls. Maybe a powerful witch from another dimension is causing chaos and their combined powers are needed to stop it.
Yes, it is. In this fanfiction, the world of Percy Jackson might be intertwined with the Mikaelson universe. It could bring together the demigod elements from Percy Jackson's story with the vampire - witch - werewolf dynamics of the Mikaelson family in some really interesting ways. For example, Percy's powers as a demigod could interact with the magic used by the Mikaelsons. Maybe there would be battles or alliances formed between the two groups that we wouldn't see in the original stories.
There are many amazing Elijah Mikaelson fanfictions. 'Elijah's Legacy' is a fanfic that looks at how he tries to leave a positive mark on the world despite his past deeds. It has some great character development. 'The Dark Side of Elijah' is interesting too as it explores the parts of him that he tries to hide from others. And 'Elijah and the New Beginning' is a story about him starting anew, away from all the chaos of his family and past.
I also like the fanfic 'Mikaelson Heir: Hope'. It focuses on Hope as she steps into her role as the heir of the Mikaelson family. It shows her facing various challenges and how she overcomes them with her unique blend of strength and compassion. There are some great character interactions that make it a must - read for any Hope Mikaelson fan.
