The story of Fem Harry Potter raised by Sirius Black could be full of twists. Sirius would have to hide her from the Ministry and Voldemort's followers. This would mean a life on the run at times. But it also means she'd be more street - smart in the wizarding world. She might grow up with a love for Sirius' motorcycle and a sense of adventure. Her time at Hogwarts would be different too. She'd have Sirius' stories in her head and might question the school's rules more often, leading to some interesting situations with the teachers.
Well, if Fem Harry Potter was raised in Japan, she might be trained in different forms of magic. Japanese magic could be more nature - based perhaps. She might learn to communicate with spirits in a more Shinto - like way. Also, her Hogwarts experience would be quite different. She could introduce some Japanese magical traditions to her classmates, like the art of origami magic where paper creations come to life.
The Fem Harry Potter raised by Sirius Black would have a complex personality. On one hand, she'd have Sirius' loyalty and sense of justice. She'd be ready to fight for what's right. On the other hand, she'd be a bit wilder. Sirius' experiences outside of the normal wizarding society would make her question things more. She might not trust authority figures as easily as the original Harry, and be more willing to break the rules if she thought they were unjust. Her personality would be a blend of Sirius' rebelliousness and the underlying goodness that Harry Potter is known for.
In a fanfiction where Harry Potter is raised by Bellatrix Black, Harry would be exposed to a very different kind of magic. Bellatrix would probably instill in him a sense of loyalty to Voldemort. His upbringing would lack the love and positive guidance he received in the original story. He might be more isolated as Bellatrix is not exactly a social butterfly. His relationship with Hogwarts might also be very different. He could see it as a place to conquer rather than a place to learn and grow.
Well, if Harry Potter was raised by Zeref, it would be a very different story. Zeref is a rather dark and complex character from Fairy Tail. Harry might grow up with a different view of magic. He could be more inclined towards darker forms of magic or have a more cynical view of the wizarding world. Maybe he would be more isolated as Zeref's influence might not be well - received in the Hogwarts environment.
The story could be amazing. Since Narnia has a different magic system than the wizarding world in Harry Potter. Harry might have to adapt quickly. He could make friends with the talking animals in Narnia. His upbringing there would probably give him a different perspective on magic and power. For example, the power of Aslan is more like a divine power compared to the magic in the wizarding world. This could lead to some interesting conflicts or collaborations when he discovers his own wizarding heritage later.
Well, if fem Harry Potter moves to Forks, it could be really interesting. She might use her magic skills in a very different setting. Maybe she'd use magic to deal with the dreary weather in Forks. And she could make some new friends with her unique abilities, who would be both fascinated and a bit scared of her magic.
Harry would likely be more confident. Sirius is a bold and brave character, and growing up with him would instill those qualities in Harry more strongly. He wouldn't be as meek as he was in the early days at Hogwarts.
If Harry was raised in Ancient Egypt, his upbringing would be very different. In Egypt, magic was deeply intertwined with religion and the afterlife. Harry could grow up believing in different deities that govern magic. His friends would probably be Egyptian wizards or witches. His Hogwarts adventures might not even happen as we know them. Instead, he could be dealing with threats specific to the Egyptian magical world, like some ancient dark magic that has been dormant for centuries.
His relationship with Sirius would be extremely strained. Since Walburga was Sirius' mother and they had a very difficult relationship, Sirius would likely see Harry as a product of his mother's influence. Harry, on the other hand, might be initially hostile towards Sirius due to being raised with Walburga's views.
In such a fanfiction, Harry would likely grow up with a very different set of values and skills. Sirius, being a rebel and a bit of a wild card, would probably teach Harry more about the unorthodox ways of magic and the Marauders' secrets. Harry might be more confident and street - smart, having been exposed to Sirius' bold personality from a young age.
