It could involve Harry being raised in a more diverse and unusual environment. Since the Al Bhed are a bit of an outcast group in their own world, Harry might develop a sense of being different that's even stronger than in the original story. He could use Al Bhed teachings about unity in diversity to bring together different wizarding groups against Voldemort. And his spells might be influenced by Al Bhed magic, if there is such a thing in this fanfiction, creating a whole new style of magic in the wizarding world.
Well, the Al Bhed have a distinct look and way of life. If Harry was raised among them, he might have different values. Instead of the pure - blood - half - blood - mudblood divide in the wizarding world, he could introduce the more inclusive Al Bhed way of thinking. His friends at Hogwarts would be quite surprised by his different upbringing. He might even bring some Al Bhed friends to Hogwarts, which would cause quite a stir as they are not part of the normal wizarding population. This would lead to new adventures and challenges as they all try to co - exist and fight against the dark forces together.
It could be more nature - based in a different way. The Al Bhed have their own relationship with the world around them. Harry's magic might incorporate elements from Al Bhed beliefs about nature. So instead of just using the typical Hogwarts spells for herbology, he could use Al Bhed - inspired magic that has a deeper connection to plants and the environment.
Well, one possibility is that Harry would be trained in combat and stealth from a very young age, much like Damian Wayne was by Talia. He might grow up with a different view of magic, perhaps more as a tool for survival and power rather than just for study at Hogwarts. Also, his relationship with the wizarding world could be very different. Instead of being excited about Hogwarts, he might see it as a place full of naive wizards who don't understand the real world threats he's been raised to face.
Well, in this fanfiction scenario, Lily raising Harry would mean he'd be protected in a different way. Instead of the Dursleys' neglect, he'd have a nurturing environment. Lily could teach him about his father in a more personal way. Maybe he'd grow up with a stronger sense of family and heritage. Also, he might not have the same sort of scar - or it could be a mark of a different kind of magic, since the circumstances of his survival would be different.
In this fanfiction concept, the story could start with Toriel finding baby Harry on her doorstep, much like how she might take in a lost child in Undertale. She would raise him with love and care, teaching him about the world in a very different way than Hogwarts. Harry would grow up with a strong sense of right and wrong, based on Toriel's moral compass. His adventures would be different too. Instead of facing Voldemort in the traditional Hogwarts setting, he might have to deal with threats to both the wizarding world and Toriel's world. And his friends could be a mix of wizards and characters from Toriel's realm, leading to some very unique interactions and story arcs.
The storyline might involve Serena bringing a whole new set of values and skills to Harry's upbringing. Maybe she'd teach him a different kind of magic, or perhaps she'd instill in him a great sense of determination and independence from a young age. It could also be that Harry would grow up with a more athletic and competitive edge, given Serena's own nature in her original context.
Well, in this fanfiction scenario, Harry would be raised in a different family environment. The Longbottoms, having their own history of struggle against the Dark Arts, would instill in Harry a sense of determination and a different perspective on the fight against Voldemort. His relationship with Neville would be complex yet interesting, as they would share a family bond. And perhaps, his magical education would have a different slant, influenced by the Longbottoms' way of doing things.
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 a really interesting story. Raiden is from a different fictional universe, so he might bring some unique skills and values to raising Harry. Maybe he'd teach Harry some super combat skills like he has in his own world. Harry would probably grow up with a different kind of discipline and power control compared to what he would have learned at Hogwarts under the Dursleys and later at the school. It could also change his view on magic and how to use it for good in a more action - oriented way.
One possibility could be that Hestia imparts her wisdom of the wizarding world to Harry in a very nurturing way. Since Hestia is the goddess of the hearth, she might create a warm and loving home environment for Harry, which is very different from his experience with the Dursleys. This could lead to Harry having a more stable emotional foundation as he grows up, and perhaps he would be less impulsive in his actions at Hogwarts.
