The fanfiction might explore how Harry's relationship with the wizarding world is different. Growing up in Potter Manor, he could be seen as a more prominent figure from a young age. The manor itself could hold hidden chambers filled with challenges and rewards. Harry could stumble upon a chamber that tests his Potter lineage, like a series of magical trials. This would not only strengthen his magical abilities but also deepen his connection to his family name and the responsibilities that come with it.
Well, in a 'Harry Potter raised in Potter Manor' fanfiction, we might see Harry having a different kind of upbringing. He could be surrounded by portraits of his ancestors who could offer him advice and wisdom. The manor itself might hold hidden chambers or libraries filled with rare magical knowledge. This could lead to Harry being more confident and self - assured when he finally goes to Hogwarts.
If Harry was raised at Potter Manor in fanfiction, it would change a great deal. He could have a more stable support system. Instead of being bullied and neglected, he'd be surrounded by the remnants of his family's magic. The manor itself might have a library filled with rare magical tomes that he could study, and perhaps there would be a family - appointed tutor for him. This would make him more confident and knowledgeable when he enters Hogwarts, and his relationships with his classmates might be different as he wouldn't have the same insecurities.
It could be that the manor trunk is enchanted in a special way. In the fanfiction, it might serve as a portal to another dimension or a time - locked chamber. Harry could accidentally open it and find himself in a different era of the wizarding world, having to figure out how to get back while also dealing with the unique challenges and characters of that time.
One possibility could be that Harry Potter grows up with a strict military - like discipline on Kamino. He might be trained in unique combat skills that are different from what he learned at Hogwarts. He could also form unexpected alliances with the Kaminoans, and use their advanced cloning technology to his advantage in the wizarding world battles.
Perhaps the story could show Harry being isolated from the wizarding world he was meant to be a part of. Since demons are raising him, they might keep him away from Hogwarts and the positive influences there. He could develop powers that are a mix of wizardry and demonic abilities, which would make him a very different kind of character in the fanfiction universe. He might also have a different view on good and evil, as demons' moral compass is not the same as that of humans or wizards.
One possibility is that Harry would grow up to be a very different person. Dementors are creatures of despair, so he might be more withdrawn and less trusting. He could also have some very dark powers, having been exposed to the dementors' influence for so long.
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.
