Yes, there might be. Fanfiction platforms are filled with all sorts of creative and out - of - the - box ideas. You can check popular fanfiction sites like Archive of Our Own or FanFiction.net. Just search for 'Percy Jackson is born a vampire' and you may find some interesting stories.
There could also be some sort of vampire elders or leaders that are part of the story. Since Edward is a born vampire, they might be interested in him or have some sort of plan regarding him. Their presence would add to the complexity of the story and the relationships within it.
Stiles is the central figure in this fanfiction. Since he's a born vampire, he has his own set of characteristics and story arcs. His father could also be a significant character. In many fanfictions, the relationship between Stiles and his father is explored, especially when his father starts to suspect that something is different about his son. Additionally, if there are any vampire mentors or antagonists in the story, they would be main characters as well. They would either guide Stiles in his vampire journey or try to stop him from achieving his goals.
Well, Bella is obviously one of the main characters. Since it's about her being born a vampire, she will be central to the story. There might also be other vampires that she interacts with, like the Cullens if it follows the Twilight universe to some extent.
One interesting plotline could be Edward exploring his unique vampire abilities from birth. For example, he might have a different way of controlling his thirst compared to other vampires. Maybe he has an innate power that helps him resist the urge to hunt humans more effectively.
One possible plot could be that Harry, as a vampire, has to hide his true nature at Hogwarts. He might struggle with the urge to drink blood while being surrounded by his wizard friends. For example, during potions class, the smell of certain ingredients could trigger his vampire instincts, making it difficult for him to focus. And he may have to find a way to obtain blood without raising suspicion, perhaps by befriending some magical creatures that can provide a substitute or by secretly using his vampire powers to hunt small, non - magical animals in the Forbidden Forest.
Well, if Naruto was born a vampire, his diet would be a huge factor. Instead of ramen, he'd be craving blood. This would put him at odds with the village's values. His growth as a ninja would be interesting. He might be faster and stronger than normal due to his vampire abilities, like enhanced speed and strength. But he'd also have to hide his true nature from most people. His dreams of becoming Hokage might be more difficult to achieve because of the prejudice against vampires in the ninja world. He could probably use his vampire powers to sense enemies better, like having a heightened sense of smell to detect hidden foes, which could give him an edge in battles.
Another vampire, an older and more powerful one, could be an antagonist. This vampire might see Percy as a threat to his power or territory. Maybe he wants to either kill Percy or make him submit to his rule.
In a 'Percy Jackson is born a vampire' fanfiction, there would be a lot of changes. For starters, his origin story would be completely different. Instead of being a demigod, he'd be a vampire. His powers would likely be a mix of his demigod powers and vampire traits. He might be able to use his water - related demigod powers in new ways because of his vampire nature. Also, his relationships with other characters would be complex. His friends might be initially scared or distrustful of him, and he'd have to prove himself. And he could have new enemies from the vampire world who might see him as a threat or an oddity.
In such a fanfiction scenario, Harry might have enhanced physical abilities like super strength and speed from the start. He could also have a natural allure, which might make his relationships with others more complex. His magical abilities might be influenced too, perhaps having a different connection to certain spells related to darkness or life-force.
