The plot could involve the fem Harry Potter having to hide her magical abilities from Batman at first, fearing his reaction. But as time goes on, he comes to accept and even help her develop her magic in ways that are unique to her situation. She could also introduce Batman to the wizarding world, which would be a huge culture shock for him. And perhaps together they could fight against threats that are both magical and non - magical, combining their different skills and knowledge.
Well, it could be that the female Harry Potter grows up with Batman's sense of justice and discipline. Maybe she learns martial arts and detective skills from him. And she might use her magic in a more stealthy and strategic way, like Batman uses his gadgets.
One possible plot twist could be that the Queen discovers Harry's magical abilities early on and decides to train her in a special way, perhaps combining magic with royal etiquette. This would give Harry a unique advantage in the wizarding world.
A plot twist could be related to Fem Harry Potter's magical abilities. Since she is raised by Crowley, she might develop some unique magical skills that are a blend of wizarding magic and Crowley's own brand of 'power'. This could make her a target for various groups in the wizarding world who either want to use her for their own gains or are afraid of her new - found powers. Also, Crowley might have some enemies in the wizarding world that he has never revealed to Fem Harry Potter. When these enemies discover her existence, they target her to get back at Crowley, putting her in great danger and forcing her to rely on skills and knowledge she has learned from Crowley to survive.
One possible plot could be that Fem Harry grows up in the harsh environment of Azkaban, developing a tough exterior. She might discover unique magical abilities due to her unusual upbringing. For example, she could have an uncanny ability to sense the emotions of dementors, which she uses to her advantage. This could lead to her being a target for both the prison guards who fear her power and those outside who want to use her for their own gain.
Well, it could be that the female Harry Potter, with her magical knowledge and skills, trains Naruto in a unique way. Maybe she teaches him spells that are somewhat similar to ninjutsu, like how to use magic to enhance his speed or strength. And she might introduce him to a whole new world of magic that Naruto then combines with his own ninja abilities.
She would probably be more brooding and reserved compared to the original Harry Potter. Batman's influence would make her keep her emotions in check more often.
The plot could be that Harry, raised by demons, has unique powers that other wizards don't. For example, he might be able to communicate with dark creatures more easily. The demons could be using Harry as a tool to infiltrate the wizarding world. When he gets to Hogwarts, he starts to question his upbringing as he sees the kindness and different ways of magic there. He has to decide whether to stay true to his demon - raised self or embrace a new way of life.
One possible plot could be that Calypso, with her magical abilities, imparts a different kind of magic knowledge to Harry. Maybe she teaches him more nature - based magic, which is different from what he would learn at Hogwarts. Harry might grow up in a more isolated and peaceful environment with Calypso, away from the prying eyes of the wizarding world in Britain. This could lead to him having a different perspective on magic and his role in the fight against Voldemort.
The fanfiction might explore how Harry's relationship with the wizarding world is different. Growing up in Potter Manor, he could be seen as a more prominent figure from a young age. The manor itself could hold hidden chambers filled with challenges and rewards. Harry could stumble upon a chamber that tests his Potter lineage, like a series of magical trials. This would not only strengthen his magical abilities but also deepen his connection to his family name and the responsibilities that come with it.
One possibility could be that Harry Potter grows up with a strict military - like discipline on Kamino. He might be trained in unique combat skills that are different from what he learned at Hogwarts. He could also form unexpected alliances with the Kaminoans, and use their advanced cloning technology to his advantage in the wizarding world battles.
Perhaps the story could show Harry being isolated from the wizarding world he was meant to be a part of. Since demons are raising him, they might keep him away from Hogwarts and the positive influences there. He could develop powers that are a mix of wizardry and demonic abilities, which would make him a very different kind of character in the fanfiction universe. He might also have a different view on good and evil, as demons' moral compass is not the same as that of humans or wizards.
