She could inherit enhanced strength. Caius is a powerful vampire, and strength is a common trait in vampire bloodlines. So Bella might be able to overpower other vampires or supernatural beings more easily.
Well, it could start with Bella being completely unaware of her connection to Caius. Caius, on the other hand, discovers her existence and decides to keep an eye on her from afar. As the story progresses, Bella might get into some trouble related to the vampire world, and Caius steps in to save her. This event could lead to a slow - building relationship where he reveals to her who he is and their family connection.
Well, Caius could be very possessive and see Bella's blindness as something that makes her even more his. He would be by her side all the time, guiding her physically when needed. He might also share his vampire senses with her in some way, like describing the world around them in vivid detail so that she can 'see' through his words. And he would definitely be very angry if anyone made fun of or took advantage of her blindness.
One interesting fanfiction could be 'The Caius Connection'. In it, Fem Harry's journey as Caius' granddaughter unfolds with her learning about the vampire world in a unique way. It has great character development and an engaging plot.
At first, it might be a bit rocky. Bella, being human and now blind, is in a very vulnerable state. Caius, as a powerful vampire, may come off as intimidating. But as time goes on, they start to develop a deep bond. Caius learns to be more gentle and caring, and Bella starts to trust him more and more.
In such a fanfiction, it could completely change the dynamics of the Twilight universe. Caius, being a powerful and somewhat cruel vampire in the Volturi, as Bella's father would bring a whole new set of storylines. Maybe he would be overly protective in a very different way compared to Charlie. He might use his vampire powers to keep Bella in a sort of 'gilded cage' for her safety, which could lead to a lot of conflict with the Cullens and other characters. It could also explore how Bella's character would develop differently, growing up with a vampire father and the knowledge of the vampire world from a very different perspective.
Yes, there could be. In the Twilight universe, while not canon, fanfiction often explores unique family relationships. Writers might create a story where Bella has a different connection to the Cullen family, making her Esme's granddaughter. It could involve alternate timelines or new backstories for the characters.
One possible scenario in such a fanfiction could be that Bella's connection to Aro as his granddaughter completely changes the dynamic of the Twilight world. Maybe she inherits some of Aro's unique vampire abilities, which would make her even more of an enigma to the other characters like Edward and Jacob. This could lead to new alliances and conflicts within the story.
The novelty of it. Combining the world of 'Harry Potter' with the 'Twilight' universe through this unique relationship is really exciting. It allows for a fresh take on both universes.
One common theme is the struggle between different vampire clans. Since Caius is part of the Volturi and Bella has her own connections, this often creates a backdrop of power struggles and politics in the fanfiction.
