One possibility is that Harry would grow up with a very different set of skills. Vergil is a powerful and complex character from the Devil May Cry series. He could train Harry in combat, both physical and magical in a way that's far more intense than what he'd get at Hogwarts. Harry might become more of a lone wolf, relying on his own strength rather than the support of friends as much as in the original series.
Well, in this fanfiction, Harry would probably have a much darker aesthetic. Vergil is often associated with darker themes. Harry's clothing style, his way of speaking and his general demeanor could be influenced. His magic might also have a different 'flavor'. Instead of the typical warm - colored spells of Hogwarts magic, his spells could be more like Vergil's blue - tinted attacks, symbolizing a more cold and calculated use of magic.
The plot could also involve a very different magical world view. Vergil has his own code of honor and sense of power. He might instill in Harry a different understanding of magic, one that's more about dominance and self - mastery. This could lead Harry to question the more benevolent and community - based magic of the wizarding world in the Harry Potter series. He might even be seen as an outcast in the wizarding world due to his unorthodox upbringing.
Well, the plot could involve Harry having a very different upbringing. Instead of the Dursleys, he'd be in Poseidon's underwater realm. He might learn water - based magic or have special powers related to the sea. Maybe he'd have a connection with sea creatures and they'd help him in his adventures, just like how his friends at Hogwarts do in the original series.
One possibility is that Harry would be trained in dark magic from a young age. He might grow up believing in the Dark Lord's ideology, which would put him at odds with his friends from the original story. For example, he could be a formidable opponent to Hermione and Ron when they eventually cross paths.
Well, it could involve Harry growing up with the Delacour family's unique culture. Maybe he'd learn different kinds of magic that the Delacours are known for. He might also have a different personality, influenced by their flamboyant and refined ways.
In a story where Harry is raised by a boggart, he could have a very distorted view of the world. The boggart, not being a normal caregiver, might not be able to provide the love and stability that a normal family would. So, Harry might be more withdrawn and distrustful. He might also have a hard time making friends at Hogwarts as his upbringing by a boggart could have made him seem strange to other students.
The story could show Harry being an outcast among wizards at first because of his mermaid - influenced behavior. For example, he might not understand some of the basic social norms in the wizarding world. However, his mermaid - raised skills could also make him a very powerful wizard in certain areas, like water - based spells or divination related to the sea.
The story could be really interesting. Maybe the female Harry Potter would have a different set of friends. Instead of Ron and Hermione, she might befriend children from noble wizarding families. Her magical education could also be different. The Queen might ensure she has the best tutors, not just from Hogwarts but from all over the wizarding world. This could lead to her having a broader knowledge of magic and different magical cultures, which would be really exciting to explore in the fanfiction.
One possibility is that Harry would grow up with a very different set of skills. Jason Winchester is often associated with hunting and survival skills. So Harry might be trained in those areas instead of magic at first. He could be more physically adept and have a more hands - on approach to dealing with threats. For example, instead of using a wand to fight off dark wizards, he might use a weapon like a knife or a gun as Jason Winchester would. Also, his view of the world could be shaped by Jason's more gritty and down - to - earth perspective, rather than the magical world view he has in the original Harry Potter series.
Well, it could be really interesting. Harry would grow up in a very different environment. Instead of the wizarding world at first, he'd be in Gotham. Bruce Wayne, being the Dark Knight, would likely train Harry in self - defense and detective skills. Harry might bring some magic into Gotham's crime - fighting, like using spells to disarm criminals instead of batarangs. It would be a whole new take on both the Harry Potter and Batman universes.
The fanfiction might explore Percy's relationships in a new light. For example, his relationship with Annabeth could be strained as he now has loyalties to Gaea. His friendships with other demigods might also change drastically. Maybe he'd be seen as a threat and have to fight against his former allies. Overall, it would be a complete upheaval of the original Percy Jackson story dynamics.
One possibility is that Naruto's connection with the summons would make him more in tune with nature. For example, if he was raised by toads, he might learn their unique jutsu faster and have a different approach to combat. He could also have a different view on friendship and loyalty as summons often have a strong bond with their summoners.
