In this fanfiction, the ghosts might protect Harry in a way that living people can't. They could give him advice based on their long years of observing Hogwarts. For example, they might tell him secrets about the founders of Hogwarts that help him in his adventures. Also, Harry's personality could be influenced by the ghosts' ethereal and somewhat detached nature, making him more introspective.
The plot could involve Harry growing up in a world where the boundaries between Greek and wizarding magic are blurred. Hecate could introduce him to magical creatures from Greek mythology. He might also have to face different kinds of dark forces that are more related to the ancient evils that Hecate has been fighting for centuries. This would make Harry a very different kind of wizard, one with a more diverse magical knowledge and power base.
One possible plot could be that Harry Potter grows up in Mordor. Sauron might train Harry in dark magic, but Harry could have an internal struggle as he has an inherent sense of good from his parents. He might try to find a way to use the power he's learning for good, against Sauron's wishes.
Well, it could be really interesting. Maybe Sasuke would teach Harry some ninja skills. Harry might grow up with a different kind of magic, a blend of wizardry and ninjutsu. He could use his wand in a more combat - like way inspired by Sasuke's fighting style.
Well, perhaps Harry would grow up with a very different kind of magic. Circe was known for her potions and transformation magic. So Harry might be an expert in those areas from a young age. He could have a more wild and unorthodox upbringing compared to his life with the Dursleys. Maybe he'd be more in tune with nature and magical creatures that Circe might have around her lair.
Well, perhaps Harry would grow up with a different kind of magic. Rosalie, if we're thinking of a vampire Rosalie from Twilight in this crossover, might teach Harry some skills related to self - defense in a very physical way. He could be more in touch with his instincts and have a different view on magic compared to how he was raised in the original Potter story.
In a 'Harry Potter raised by dragons' fanfiction, the plot could be really exciting. Harry's upbringing by dragons would give him unique skills. For example, he might be able to understand dragon language which could hold ancient magic secrets. His moral compass could be different too, as dragons have their own code of survival. Maybe he would see the wizarding world from an outsider's perspective, since his values are shaped by the dragons.
In this fanfiction, Harry might learn survival skills from the wolves at a very young age. He could be more ferocious in a fight compared to the normal Harry. His view of the wizarding world would be quite different. Since he was raised by wolves, he might find it hard to adapt to the social norms of wizards at first. Maybe he would communicate in a more primal way, and his magical abilities could be intertwined with the wild nature he was exposed to.
In such a fanfiction, Deadpool would likely introduce Harry to a world of chaos. Harry's upbringing would be full of Deadpool's crazy antics. He might take Harry on adventures that are not part of the normal Hogwarts curriculum. And Harry would probably be more open to breaking the rules and thinking outside the box when it comes to dealing with the Dark Arts.
One possible plot could be that Hera, being a powerful goddess, would raise Harry in a world that's a blend of the wizarding world and the realm of Greek mythology. Harry might learn magic in a very different way, perhaps with more of a focus on the divine and natural elements that Hera represents. He could also have different relationships with the characters in the wizarding world. For example, his relationship with Dumbledore might be more of a power - struggle as Hera may not want Dumbledore to have too much influence over Harry.
Well, one possible plot could be that Magneto, with his strong views on mutants and power, would train Harry to be extremely powerful in magic. Harry might grow up with a more aggressive stance towards those who oppose him, like Voldemort. He could use his magic in ways that are more combat - oriented from a young age.
