In this fanfiction, Harry could be raised in a more secluded and wild environment due to Artemis's influence. He may have a different set of values compared to the Harry in the original series. Instead of Hogwarts being his main focus initially, he might be more interested in protecting the forest and its creatures. His magical education could also be a blend of Hogwarts' teachings and the wisdom Artemis imparts, like how to use magic for survival in the wild.
The story could involve Harry being trained by Artemis in stealth and tracking. This would give him an edge in the wizarding world. He might also have a different relationship with magic items. For instance, he could view the invisibility cloak not just as a tool for sneaking around Hogwarts, but as something that could be used in a more 'hunter - like' way to stalk dark wizards in the forest. His bond with animals, especially those associated with Artemis, would be much stronger, and he could communicate with them in ways other wizards can't.
One possible plot could be that Naruto, being raised by Artemis, might gain some unique skills related to archery and hunting. He could also develop a different personality, perhaps more in tune with the wild and nature. Maybe he'd have a special bond with the animals that Artemis is associated with.
Maybe Harry discovers he has a connection to Artemis and becomes a Hunter. He could use his magic skills along with the hunting abilities. For example, he might use magic to track down magical creatures that are also targets for the Hunters. He could face challenges from both the wizarding world, like Voldemort's followers, and the challenges within the Hunter of Artemis community, like rival Hunters or ancient curses related to the hunting.
Perhaps there's a prophecy that involves both of them. They are forced to work together to figure out what it means. Along the way, they discover they have a deep connection, not just because of the prophecy but also because of their shared values of courage and loyalty. This connection eventually leads to marriage.
The plot could be that Harry, raised by demons, has unique powers that other wizards don't. For example, he might be able to communicate with dark creatures more easily. The demons could be using Harry as a tool to infiltrate the wizarding world. When he gets to Hogwarts, he starts to question his upbringing as he sees the kindness and different ways of magic there. He has to decide whether to stay true to his demon - raised self or embrace a new way of life.
One possible plot could be that Calypso, with her magical abilities, imparts a different kind of magic knowledge to Harry. Maybe she teaches him more nature - based magic, which is different from what he would learn at Hogwarts. Harry might grow up in a more isolated and peaceful environment with Calypso, away from the prying eyes of the wizarding world in Britain. This could lead to him having a different perspective on magic and his role in the fight against Voldemort.
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.
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.
