If Naruto were raised by demons in fanfiction, he'd likely possess unique powers. Demons are often associated with dark and arcane magic. So Naruto could have abilities that are not seen in the normal Naruto universe, like the power to summon demonic creatures to fight for him. His view of friendship and loyalty might also be warped, as demons have different social structures compared to humans.
His character would likely be more aggressive. Demons are often seen as violent and forceful, and Naruto raised by them might adopt these traits. He may be quicker to anger and less likely to show mercy in combat.
Yes, there might be such a fanfiction out there. The Naruto fandom is quite large and diverse, with fans creating all sorts of unique and imaginative stories. Some fans like to explore alternative family relations for the characters, and the idea of Naruto being related to demons in some way could be an interesting concept for a fan - created story.
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.
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.
It could be the Nine - Tailed Fox. Since it already has a connection to Naruto, it might take him under its wing in a more fatherly or family - like way. Another possibility is some of the lesser - known demons from the Naruto lore that haven't been explored much.
One possible scenario in this fanfiction could be that Naruto grows up with a more balanced upbringing. Tsunade might teach him medical ninjutsu and how to control his emotions better. Jiraiya, on the other hand, would surely train him in powerful combat techniques and in the ways of the sage. Naruto would probably be more mature and well - rounded at an earlier age, with a combination of Tsunade's tough love and Jiraiya's adventurous spirit guiding him.
One possible scenario in this fanfiction could be that Naruto grows up with the Namikaze Clan's unique jutsu training methods. He might inherit some of Minato's (a Namikaze) speed and intelligence in combat at a much earlier age. This could lead to him being a more confident and skilled ninja from the start, as the Namikaze Clan has a reputation for their strong abilities.
Well, it depends on personal taste. Some people might find it really exciting as it could bring a new and dark twist to the Naruto universe. The idea of Naruto being associated with the 'king of demons' has the potential to explore different power dynamics and character developments.
