Rosalie's vampire nature would mean she has a strong sense of protectiveness towards Harry. She might be overly cautious about his safety, sometimes to the point where Harry feels a bit smothered. For example, she might not let him go out alone at night in case he encounters dark creatures. However, her super - strength and speed could also be used to protect him from any immediate threats, like if Death Eaters were to attack.
The plot could involve Rosalie sensing that Harry has a special power that is not just related to his wizardry. She decides to adopt him to keep him safe from the dark forces in both the wizarding world and the vampire world. Rosalie would have to deal with the magical aspects of Harry's life that she doesn't fully understand at first. But with time, she helps him hone his skills. Harry, in turn, might introduce Rosalie to the concept of love and friendship in a way that vampires don't usually experience. This could lead to a change in Rosalie's view of the world and her place in it.
They could interact through a magical accident. For instance, a spell gone wrong could open a portal that brings Rosalie into Harry's world. Then they'd have to figure out how to get her back while also dealing with the threats in the wizarding world like Voldemort.
One common theme is the clash of different worlds. Since Rosalie Hale is from the 'Twilight' universe and Harry Potter is from his own wizarding world, fanfictions often explore how these two very different worlds collide and interact. For example, in many stories, Rosalie has to adapt to the magic and culture of Hogwarts which is very different from her vampire world.
One interesting fanfiction could be where Rosalie Hale somehow gets transported into the Harry Potter world. Maybe she uses her vampire abilities to help Harry in a battle. For example, her super strength and speed could give them an edge against the Death Eaters.
It could cause a great deal of shock and unease at first. Wizards have always been a bit wary of vampires. But if Harry and the vampire princess work together to show that their union is for the good of all, it could gradually lead to more acceptance. Their relationship might inspire new magical research into the nature of vampires and how their magic can interact with wizard magic.
Harry would likely become more confident in his pure - blood heritage. Growing up with Narcissa, he'd be exposed to different values and traditions, which could make him more well - rounded. He might also be less impulsive as he'd be in a more controlled environment.
The relationship could be developed through a mutual goal of protecting someone or something. For example, they could both be on a mission to protect a group of humans from other dangerous vampires. Working together towards this goal would build trust and understanding between them, and as they face various challenges along the way, their love for each other would grow in a more complex and interesting way.
Yes, there are some. You can start by looking on popular fanfiction websites like Fanfiction.net or Archive of Our Own. Just search for the specific pairing in their search bars.
The vampire's nocturnal nature can add an interesting twist. For example, Harry might have to adjust his schedule to fit the vampire's. Also, the vampire's need for blood could create moral dilemmas. If the vampire refuses to drink human blood, it shows his self - control, but it might also make him weaker at times, which could put Harry in danger.
Some of Harry's friends might be initially shocked. Ron, for instance, could be quite skeptical and voice his concerns about the age difference. Hermione, on the other hand, might be more open - minded at first, but as she sees how the relationship impacts Harry's studies or his role in the fight against dark forces, she could start to have doubts.
