Well, in this fanfiction, perhaps Fem Harry is trained by Itachi to be a master of stealth. In the wizarding world, she would be able to use these skills to her advantage, for example, when sneaking around Hogwarts to uncover secrets or avoid Death Eaters. Itachi could also instill in her the importance of self - sacrifice for the greater good. So, when the final battle against Voldemort comes, Fem Harry might be more willing to put herself in harm's way to protect others, just like Itachi did for his village.
A possible plot could be Fem Harry's introduction to the Uchiha clan's history and culture by Itachi. This would make her view the concept of family and loyalty in a different way compared to the pure - blood and half - blood ideas in the wizarding world. Also, Itachi's calm and collected nature could help Fem Harry deal with her own emotional turmoil, especially when facing the prejudice against her as a 'female Harry'. She could learn from Itachi how to keep her emotions in check and use her intelligence to outwit her opponents.
One interesting plot idea could be Fem Harry learning Itachi's unique jutsu skills. Since Itachi is a highly skilled ninja, he could teach her how to use Sharingan - related techniques, which would give her an edge in the wizarding world. Another idea is that Fem Harry's moral compass gets influenced by Itachi's complex sense of right and wrong. Itachi's past actions in the Naruto universe were often driven by a greater good, and Fem Harry might adopt a similar view in dealing with the threats in the wizarding world, like Voldemort.
One idea could be that Fem Harry shows a great aptitude for magic early on, much like her father James. She might have a special bond with James as he trains her privately. Another could be that she faces unique challenges in Hogwarts due to being female in a story where the original Harry was male, like different social interactions.
One interesting plot idea could be that Snape raises Harry with a strict but fair hand. He teaches Harry about the Dark Arts not to encourage him to use them, but to make him fully aware of the dangers. Harry might grow up with a more nuanced view of Snape from the start, and their relationship could be a mix of father - son dynamic and teacher - student. For example, Snape could train Harry in potions from a very young age, leading Harry to become a master of potions himself much earlier than in the original story.
One idea could be Harry being raised by the Weasleys from a very young age. He'd grow up with their large family dynamic, learning magic in a more chaotic but loving environment. It might change his personality a bit, making him more outgoing and confident earlier. Another plot could be him being raised by Remus Lupin. Lupin would instill in him a deep understanding of the dark arts in a more academic way, and also teach him about acceptance of his own lycanthropy - like condition if he were to inherit it. And a third idea is Harry being raised by the centaurs in the Forbidden Forest. He'd learn their unique brand of magic, which is more in tune with nature, and have a different perspective on the wizarding world and its relationship with the natural world.
Well, he could be raised in a small, idyllic French village full of magic. The local wizards there might be more in tune with nature magic. So, Harry grows up learning how to communicate with magical creatures in the French forests in a way that's different from what he'd learn in Britain. Maybe there's a mystery about his parents in the French wizarding world too. Like, they were involved in some secret mission in France before they died, and as he grows up, he starts to uncover clues about it.
One idea could be that they grow up learning magic together in a unique way. Maybe they discover a new spell or form of magic that no one else has. Another plot could involve them facing a common enemy from a young age and having to rely on each other's unique skills. For example, Fleur's Veela charm and Harry's Gryffindor courage could combine to defeat the foe.
Well, perhaps in this fanfic, Harry is raised by Voldemort to be his ultimate weapon against the wizarding world. He's trained to be extremely powerful in combat magic. But as he grows, he starts to notice the fear and suffering Voldemort causes. This could lead to an internal struggle within Harry, between his loyalty to the man who raised him and his own sense of right and wrong. Also, there could be a plot where Harry uses his unique position to secretly undermine Voldemort's plans from within his own ranks.
Well, a great plot might be that the protagonist raised by Pokémon has to use the unique bond with their Pokémon family to save the Pokémon world from a new, mysterious threat. For example, if raised by a Bulbasaur, the character might understand the language of plants better and use that knowledge to combat an evil force that's corrupting the natural balance. Or, if by a Jigglypuff, they could have an uncanny ability to put enemies to sleep with a special lullaby learned from their Jigglypuff guardian. Also, the story could explore how the character, raised in a Pokémon - centric way, has a different view on the relationship between humans and Pokémon compared to normal trainers.
One plot idea could be that Harry is raised by Dementors. He might grow up with a very different view on life and magic. Since Dementors feed on positive emotions, he could struggle to understand concepts like love and friendship in the same way as in the original story. Another could be if he was raised by a group of Acromantulas. He'd likely be more in tune with the Forbidden Forest and its secrets, and might have a natural ability to communicate with spiders, which would be a very strange and unique power compared to his normal Gryffindor traits.
One interesting plot idea could be that Merlin teaches Harry ancient magic that has been long forgotten in the wizarding world. This gives Harry an edge in dealing with Voldemort. Another could be that under Merlin's guidance, Harry discovers a whole new world of magical creatures that were thought to be extinct. Maybe they hold the key to defeating the dark forces. Also, Merlin could train Harry in a more holistic way of magic, not just spells and potions, but also in the spiritual and ethical aspects of magic use.
One idea could be that Fem Harry inherits Luna's unique perception of the wizarding world. She might see magical creatures that others overlook, and this ability could lead her on adventures to protect these creatures. For example, she could discover a new breed of magical beast that is being hunted by dark wizards.
