Perhaps Gai, being a character with strong beliefs, would raise Harry to have a different perspective on the battle between good and evil. Instead of the traditional black - and - white view in the Harry Potter series, Harry, under Gai's influence, might see that there are more shades of gray. Gai could also introduce Harry to a different set of allies and enemies, which would completely change the course of Harry's adventures in the wizarding world.
Maybe it's an existing minor character from the Harry Potter universe who is given a new identity and role as 'gai'. For example, a little - known wizard who has been living in seclusion but has some extraordinary abilities and decides to take Harry under his wing.
Perhaps in this fanfiction, the goddess protects Harry from Voldemort right from the start. She could raise him in a hidden, magical realm where Voldemort can't reach. Harry would then grow up with a sense of security and a different kind of magical upbringing. He might learn to control his magic in ways that are more instinctual and natural, as influenced by the goddess.
The plot could involve Harry being trained in unique ninja skills by the Akatsuki members. He might learn their combat techniques and use them against the dark forces in the wizarding world. For example, he could use Akatsuki - style stealth to infiltrate Voldemort's lairs.
One possible plot could be that Harry Potter, instead of growing up with the Dursleys, is found by the Winchesters. They would likely train him in hunting skills as well as magic. Harry might use his magic to aid the Winchesters in their battles against demons and other supernatural creatures. And he could also introduce them to the wizarding world, creating a whole new set of adventures and challenges as they try to co - exist in both worlds.
Well, perhaps Zatanna could use her magic to protect Harry from the Dursleys. She might teach him her unique brand of magic early on, which could give him an edge in the wizarding world. He could grow up learning both Zatanna's style of magic and the traditional Hogwarts magic, making him an even more powerful wizard.
Well, one possible plot could be that Harry grows up in the world of Madoka. He might be exposed to the magical girl system instead of the wizarding world's magic. Maybe he would have to make contracts like the magical girls in Madoka, but with his own sense of justice and the knowledge he has from his original life. This could lead to some really interesting crossovers where he tries to use his skills to fight the witches in the Madoka universe.
Well, perhaps Kaguya would use her otherworldly powers to protect Harry from Voldemort. Maybe she'd teach him some unique magic that's different from the wizarding world in Harry Potter. For example, she could introduce him to some ancient spells from her own realm.
The story could start with the apes rescuing Harry from the ruins of his parents' house. As he grows up among them, he doesn't know about the wizarding world at first. But then, as he gets older, strange things start to happen around him. Magic starts to manifest in ways that are different from how it usually does. For example, his accidental magic might be related to his ape - influenced instincts, like making vines grow to protect his ape family. Eventually, he might be discovered by the wizarding world and have to learn to adapt to both his ape - raised self and his new wizard identity.
One possible plot could be that Alucard, with his dark and powerful nature, trains Harry in unique ways. Harry might learn combat skills that are a blend of magic and Alucard's vampiric abilities. For example, he could be taught to move with super - speed or have enhanced senses in addition to his magical powers. Alucard could also introduce Harry to a different view of the magical world, one that is more shadowy and filled with secrets not known in the wizarding society Harry was born into.
One possible plot could be that Harry Potter, after some sort of magical accident or portal opening, ends up in the world of RWBY. The RWBY characters, perhaps Ruby herself, find him as a baby or young child and decide to raise him. Harry would grow up learning about the Grimm and Huntsmen, while also having his own magical abilities. This could lead to some interesting combinations in combat, like using magic along with a weapon like Crescent Rose.
