The tone might become more fantastical. While the original Harry Potter series is already full of magic, the Fae bring their own brand of otherworldly magic. So, with Harry as a Fae prince, the story could have more elaborate and strange magical elements, like Fae - specific spells or rituals. This would change the overall feel of the story from a more traditional wizarding tale to something that has a broader and more exotic magical scope.
Fae inheritance often adds new elements of mystery. Since Fae lore is full of secrets and ancient knowledge, it can introduce new plotlines. For example, a character with Fae inheritance might be on a quest to discover their true Fae heritage, which could lead them to hidden places and forgotten magic in the Harry Potter world. This can also affect relationships as other characters may be curious, envious or afraid of those with Fae inheritance.
The overall mood of the story becomes more of an underdog tale. Harry has to fight against the perception that he's a squib. This could lead to him having to prove himself constantly. In the original story, he had his magic as a sort of safety net. Here, he has to find other ways to show his value. He may start to explore areas of the wizarding world that are not so reliant on raw magical power, like magical history or the study of magical creatures from a non - combat perspective.
It changes the power dynamics. In the original, Harry had some level of protection within Hogwarts. But as a fugitive, he has to rely on his own wits and skills more. So, the fanfiction concept makes him more self - reliant.
It changes the magic system. Instead of just relying on wands and spells, Harry can now access Pegasus - related magic. For instance, he might be able to heal faster like Pegasi are known for their resilience. It also changes his social status. He is no longer just a famous wizard, but also a mythical being's son, which makes him more of an enigma.
It changes it a great deal. For one, Harry's origin story gets a major rewrite. Instead of just being a wizard orphan, he now has a connection to Dracula. His abilities would likely be different. He might not just rely on his wand for magic but also have inborn vampiric powers like super speed or the ability to hypnotize. His friends might view him differently too, perhaps with a bit of fear or wariness.
The relationships between characters would also be altered. Hermione and Ron might be even more protective of Harry, but also more suspicious. They would constantly be on the lookout for any signs that the Horcrux is influencing Harry negatively. Dumbledore's plans, if he were still alive in the fanfiction, would have to be completely re - thought. The prophecy might take on a new meaning as well, since Harry now has a part of Voldemort's soul within him. All in all, it's a major plot - twisting concept.
His relationships would also change. His friends might be a bit more cautious around him at first when they find out. Hermione, for instance, would be researching ways to help him control his wolf side. And his relationship with Professor Lupin could be even more complex as they now share this wolf - related identity.
It also changes the way he is perceived. In normal stories, he is seen as a hero who can physically fight. But now, his heroism might be more about mental strength and using his intelligence. For example, he might use his smarts to outwit villains instead of using physical combat skills. And his friends might have to protect him more physically in dangerous situations.
The plot can be significantly different. Her Veela nature might attract unwanted attention, like from dark wizards who want to use her power. Also, in the original story, Harry was often underestimated, but as a Veela, fem Harry might be underestimated in a different way or even feared in some cases. Her Veela heritage could also mean she has different magical abilities that can change how she faces challenges at Hogwarts. For instance, she might be able to use her Veela allure to manipulate certain situations or people, which is a very different approach compared to the original Harry.
The relationships that Harry was supposed to form later in life, like his friendships with Ron and Hermione, would never happen. And the whole wizarding world would be different. Without Harry, there might not be someone to stand up to Voldemort in the same way. So, the power balance in the wizarding world would be completely shifted. Also, the mystery around Harry's scar and his connection to Voldemort would be left unresolved in a way that leaves the story with a sense of incompleteness.
