Well, one possibility could be that Harry grows up with a completely different set of values. Maybe he's taught dark magic from a young age and has a very different view of the wizarding world. He might see Muggles as inferior or be more inclined towards using magic for self - gain rather than for good.
Harry would probably be more attuned to dark magic. His upbringing by Satan would expose him to different forms of magic and he would have a different understanding of power. He might be more ruthless in achieving his goals and less concerned about the consequences for others. For example, in the original series, Harry was always worried about the safety of his friends, but in this fanfiction, he might use his friends as pawns if it served his purpose.
Yes, there might be such a fanfiction in the vast world of fan - created works. However, this is a very non - canonical and often extreme interpretation. The 'Harry Potter' series by J.K. Rowling has its own well - established lore and character relationships, and this fanfiction idea goes against the original spirit in a major way.
Well, perhaps Kaguya would use her otherworldly powers to protect Harry from Voldemort. Maybe she'd teach him some unique magic that's different from the wizarding world in Harry Potter. For example, she could introduce him to some ancient spells from her own realm.
Well, one possible plot could be that Magneto, with his strong views on mutants and power, would train Harry to be extremely powerful in magic. Harry might grow up with a more aggressive stance towards those who oppose him, like Voldemort. He could use his magic in ways that are more combat - oriented from a young age.
In a 'Harry Potter raised on Mars' fanfiction, the story could start with a strange magical accident that lands Harry on Mars. There, he is raised by a lone wizard who has been exiled there for some unknown reason. The wizard teaches Harry about magic in the context of the Martian landscape. Harry might develop new spells or ways of using magic that are specific to Mars. For example, he could use the low - gravity to enhance the power of levitation spells. He would also face challenges like the extreme climate and the mystery of the Martian ruins, which could hold some powerful magical secrets related to his past or the future of both Earth and Mars.
In such a fanfiction, perhaps Harry would grow up with a more nurturing and understanding environment. Lupin could teach Harry about the wizarding world in a very different way than the Dursleys. He'd likely introduce Harry to magic earlier and help him better understand his parents' legacy.
In such a fanfiction, perhaps Harry would grow up with a different set of values. Charlus Potter might instill in him a more traditional pure - blood wizarding family's values. He could be trained in advanced magic from a very young age, having access to family secrets and spells that he didn't get in the original story. This could make Harry a more powerful and confident wizard earlier on, and his relationships with other characters like Ron and Hermione might develop differently as his upbringing shapes his personality in a new way.
In a 'Harry Potter raised by Merlin' fanfiction, the plot could be really interesting. Merlin, being an extremely powerful and knowledgeable wizard, would raise Harry in a secluded place perhaps. He would teach Harry not only spells but also the ethics and history of magic in a very detailed manner. Harry would grow up with a different set of values compared to the ones he would have if raised by the Dursleys. His view on dark magic might be more nuanced as Merlin has seen the rise and fall of many dark wizards. Also, his relationship with other magical creatures would be different. For instance, he might befriend centaurs or merpeople in a more profound way because Merlin could introduce him to them in a respectful and understanding way. This would make his adventures at Hogwarts and beyond quite different from the original story.
The plot could involve Harry growing up in a world where the boundaries between Greek and wizarding magic are blurred. Hecate could introduce him to magical creatures from Greek mythology. He might also have to face different kinds of dark forces that are more related to the ancient evils that Hecate has been fighting for centuries. This would make Harry a very different kind of wizard, one with a more diverse magical knowledge and power base.
In such a fanfiction, Deadpool would likely introduce Harry to a world of chaos. Harry's upbringing would be full of Deadpool's crazy antics. He might take Harry on adventures that are not part of the normal Hogwarts curriculum. And Harry would probably be more open to breaking the rules and thinking outside the box when it comes to dealing with the Dark Arts.
