In this kind of fanfiction, one possible scenario is that Harry's whole view of the wizarding world would be warped. Voldemort might try to mold Harry into his own image. He could teach Harry dark magic instead of the traditional magic taught at Hogwarts. Harry might grow up with a completely different set of values and powers, which would surely change the whole dynamic of the fight against good and evil in the wizarding world.
In this kind of fanfiction, Harry might grow up in a very different environment. Poppy is a healer, so she could potentially raise Harry with a great deal of medical knowledge. He might learn about healing spells and potions from a very young age. Also, Poppy's kind nature would likely give Harry a more nurturing upbringing compared to his life with the Dursleys.
Well, Harry would probably have a very different upbringing. He'd be surrounded by Dumbledore's wisdom all the time. He might learn magic at a much faster pace and gain deeper insights into the wizarding world's history and secrets right from the start. Dumbledore could also protect him more effectively from the dark forces, as he's one of the most powerful wizards. And Harry would grow up in an environment full of magic and knowledge, which would shape him into a different kind of wizard compared to the original story.
In such a fanfiction, Naruto might be introduced to a whole new world of magic. He could learn spells and potions, which would be a wild contrast to his ninja skills. Maybe he'd use his chakra in unique ways in the magical world. For example, he could infuse his chakra into a magic spell to make it more powerful. Also, he'd probably make some interesting friends among the Hogwarts students, and his determination and never - give - up attitude would surely inspire them.
Well, one possibility is that Harry would be exposed to a whole new world of magic. Dr. Strange's magic is very different from the magic in the Harry Potter universe. Harry might learn new spells and ways of using magic that could make him even more powerful. He could also get involved in Dr. Strange's battles against otherworldly threats, which would be a huge change from his battles with Voldemort.
The Weasleys could be likely adoptive parents. They already have a big family and a warm, loving home. They understand the importance of family and would surely welcome Harry with open arms. They could give Harry the sense of a proper family that he has always longed for.
When Harry is adopted by Poppy, it might lead to a change in the main plotlines. For example, Voldemort may not target Harry in the same way. Since Harry is under Poppy's care, he could be better protected. Poppy might train Harry in some unique forms of magic related to protection and healing. This could make Harry a more well - rounded wizard earlier in his life. And his relationships with other characters would also shift. Teachers might view him differently as he is now associated with Poppy, a respected figure at Hogwarts.
Well, it would change his life drastically. Firstly, he'd be in a completely different cultural and magical setting. Kuroka's world likely has different magic rules and social norms. Harry would probably learn new magic skills that are unique to that world. Also, he'd be away from the Dursleys and the whole Voldemort threat in the wizarding world he originally knew. He might form new relationships with the characters in Kuroka's world and grow up with a different set of values.
The Weasleys are very common. Given their big hearted nature and their closeness to Harry in the original story, it makes sense for them to adopt him in fanfiction. They already treat him like family, so it's a natural fit.
His character would likely be very different. He might be more cynical. Growing up with Voldemort, he would be exposed to a lot of dark and cruel things. He may start to question the concepts of good and evil as they are traditionally defined in the wizarding world.
