It could be really interesting. Kreacher, being a rather complex and initially prejudiced house - elf, would raise Harry in a very different way from the Dursleys. Harry might grow up with a deep knowledge of the Black family secrets and traditions. He could also be more in tune with the wizarding world's darker elements from a young age.
Well, in such a fanfiction, Harry might be taught by Kreacher about the importance of loyalty to one's family, which in Kreacher's view would be the Black family. This could lead to Harry having a different perspective on his own family, including the Potters. Also, Kreacher's cooking skills, which are mentioned in the books, might mean Harry has a very different diet compared to canon. He might be fed traditional elf - made wizarding food that has unique magical properties.
It would be a unique take on the Harry Potter story. Kreacher is a complex character. He could raise Harry in a way that emphasizes self - sufficiency and loyalty to a fault. Harry might not be as eager to jump into the fight against Voldemort as in the original story. Instead, he could be more focused on protecting his own little world created by Kreacher. Also, his magic could develop in a more unorthodox way due to Kreacher's unorthodox teaching methods.
Kreacher is a very traditional character. His influence on Harry could mean that Harry is more into the old magic. He might be taught spells and incantations that are not commonly known in modern wizarding society. Also, Kreacher's loyalty to the Black family could make Harry more protective of the remaining members of the family and their heritage.
In this fanfiction, the plot might revolve around Harry's struggle to balance Kreacher's teachings with the values of the wider wizarding world. He could face discrimination from other wizards who are suspicious of his upbringing. Meanwhile, Voldemort might see Harry as an even greater threat because he's been raised by Kreacher. Kreacher, being protective, tries to shield Harry from the Dark Lord, but Harry realizes he has to take a stand. This could lead to a series of battles and adventures where Harry has to prove himself not just as a wizard, but as a person with his own set of beliefs.
It could be amazing. Maybe Harry would grow up with a stronger sense of family heritage. He might have access to more hidden magic within the castle walls from an early age. And he could form different relationships with the portraits and ghosts in the castle compared to his original upbringing.
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.
Well, it could be really interesting. Harry would probably grow up with a very different set of values. Goku is all about strength and protecting the Earth in a very physical way. Harry might learn martial arts instead of magic at first. He could be more straightforward in dealing with his enemies, using punches rather than spells. And his idea of friendship might be more like Goku's, based on mutual respect for power and a shared goal of protecting those in need.
It could be really interesting. Yugi has a kind heart and strong sense of justice from Yu - Gi - Oh. If he raised Harry Potter, he might teach Harry some unique strategies and ways of thinking. Maybe Harry would learn to play Duel Monsters instead of Quidditch at first. Also, Yugi's experience with the Millennium Puzzle could give Harry a different perspective on magic and mystery.
In such a fanfiction, Harry would be raised in a shinobi culture. Firstly, his upbringing would be centered around the values of the shinobi, like loyalty to the village and comrades. He'd learn to move silently, use weapons like kunai and shuriken. His Hogwarts - like education would be replaced with training in the ninja arts. His friends could be other young shinobi, and they'd go on missions together. Instead of using a wand for magic, he'd use hand signs and chakra to perform amazing feats. The story could also explore how his 'shinobi - like' thinking would influence the wizarding world if he ever returned to it.
It would be a very dark and different take on the Harry Potter story. Harry would grow up in a harsh and unforgiving environment, which would likely make him a much more hardened and perhaps distrustful person. His view of magic and the wizarding world would be colored by the prison setting, and his relationships with other characters would be extremely strained as they'd see him as an outcast from the start.
It would probably be a very strange and interesting story. Harry might grow up with orcish values and skills, which would be completely different from his wizarding world upbringing in the original series. Maybe he'd be tougher and more battle - ready, but also struggle with the differences between orc culture and the wizarding culture he was born into.
