The vampires raising her could be protecting her from a greater evil in the wizarding world. They might know of a prophecy that involves her and they are grooming her to be a powerful force against this threat. This would add an interesting layer to the story as she grows up believing she is a normal witch but slowly discovers her true purpose and the power she holds within her, all while having to deal with the prejudice against her vampiric upbringing.
One idea could be that the vampires, being from an ancient and noble line, teach her unique forms of magic that are different from what she would learn at Hogwarts. For example, they might teach her how to use her magic in a more instinctual and primal way. In this fanfiction, the female Harry Potter could also have enhanced senses due to being raised by vampires, which would give her an edge in her magical adventures.
Emotionally, she could be more aloof or mysterious. Growing up with vampires, she may have learned to keep her emotions in check. However, she might also have a fierce loyalty to those she considers family, which in this case would be the vampires who raised her. In her relationships at Hogwarts, she might have a hard time making friends at first because of her unusual background.
Well, it could be really interesting. Harry might grow up with different values compared to the original story. He could have enhanced physical abilities like super speed and strength from the vampire influence. Maybe he'd also have a different view on magic, combining vampire powers with wizardry in unique ways.
I'm not sure specifically about the most popular ones, but there are likely quite a few out there. You can check fanfiction websites like Archive of Our Own or FanFiction.net. Just search for 'Harry Potter raised by vampires' and you'll probably find some interesting reads.
Perhaps there could be a vampire clan leader named Viktor. He would be responsible for Harry's upbringing in the vampire community. He would teach Harry about the rules and traditions of the vampires. There might also be a young and rebellious vampire, Damien, who becomes like an older brother to Harry and shows him the ropes in a more unconventional way.
One idea could be a crossover where a vampire from the Harry Potter universe somehow ends up in the world of Tokyo Ghoul. Maybe a vampire who was hiding in the Forbidden Forest gets transported to Tokyo and has to adapt to the new rules of the Tokyo Ghoul world, dealing with ghouls and the CCG. This could lead to some interesting power dynamics as the vampire's magic might be a new factor in the Tokyo Ghoul ecosystem.
One possible plot could be that Harry grows up with unique vampire abilities. Maybe he has enhanced speed and strength like his vampire guardians. He might also struggle with the vampire lifestyle, like having to drink blood in some form while still having his own moral compass.
Yes, there are likely fanfictions out there with the concept of the 'father of vampires' in the Harry Potter universe. Fanfiction writers often come up with creative and unique ideas that blend different elements of the HP world. You can try searching on fanfiction websites like FanFiction.net or Archive of Our Own to find such stories.
One popular fanfiction with this concept might be 'The Unthinkable' (this is just an example, not an actual well - known title with this exact plot). In many such fanfictions, it explores how Snape's personality would influence Harry's upbringing. Snape, being strict yet intelligent, could instill in Harry a different set of values compared to the Dursleys or even Dumbledore's influence in the original series.
One interesting idea could be how Harry's personality might be different. Maybe he'd have a more unique set of skills or values influenced by Zat. Another aspect could be the relationships he forms. His friendships might take on different dynamics compared to the original story.
In some 'Harry Potter raised differently' fanfictions, he could be raised by the Malfoys. This would lead to a very different Hogwarts experience for him. He might have a more Slytherin - influenced view of magic and the wizarding world.
