His relationships would be different. He wouldn't have the same kind of friendships as he did at Hogwarts. Instead, he'd form more tenuous alliances based on mutual self - interest. His view of magic would expand greatly as he discovers the different types of magic users and creatures in the Dresden Files world. This new exposure would shape his character into someone more complex and adaptable.
He could bring some of his unique spells from Hogwarts. His Patronus charm could be a very useful tool in the often - dark and dangerous Dresden Files world. It could help him fight off some of the nastier creatures there. On the other hand, the wizards in the Dresden Files might view him with suspicion at first, not knowing exactly where his loyalties lie.
One interesting crossover could be the use of magic systems. In the Dresden Files, magic is more gritty and has a cost, while in Harry Potter it's more structured. A fanfiction might explore what happens when a wizard from Harry Potter's world tries to use Dresden Files magic, or vice versa.
Well, in the original Harry Potter, magic is often about waving a wand and saying a spell. But in the Dresden Files, it's more about willpower and knowledge of the supernatural. In fanfiction, they might blend these. For example, a character might use a Harry Potter spell but with the added requirement of Dresden Files - style willpower.
His character would likely be more hardened. Growing up with the Akatsuki, he'd be exposed to a lot of tough situations and battles early on. This would make him less naive compared to the original Harry. He might be more cynical about the idea of pure good and pure evil, having been around the Akatsuki who operate in a more morally complex world. Also, his sense of loyalty might be different. While he'd still value his friends, it might be in a more guarded way as the Akatsuki don't always trust easily.
He would become more humble. Losing his magic would make him realize that he's not invincible. He'd start to value the people around him more. For instance, he'd be more grateful for Hermione's intelligence and Ron's loyalty.
Growing up with Zatanna, Harry would develop a stronger sense of showmanship in his magic. He may not be as reserved when it comes to displaying his magical abilities. Also, Zatanna's moral code, which may be different from what he would have learned at Hogwarts, could shape him into a wizard with a more fluid view of what is right and wrong in the magical world. This could lead to some interesting conflicts and decisions as he grows older and faces the challenges in the wizarding world.
He'd probably become more reserved. Growing up with the Cullens, who are often cautious and secretive, he'd pick up on those traits. His Gryffindor courage might be tempered with the Cullens' more calculating approach to life.
His creativity would likely expand. Since he's teaching himself fanfiction, he would start to view his own world from different perspectives. This could make him more empathetic towards others in the wizarding world as he tries to understand different characters' motives and feelings through writing.
In this fanfiction, Harry's character would develop in a very different direction. He would likely be more of an outcast. Growing up with a Nundu, he wouldn't have the normal social interactions a wizard kid has. So, he could be more withdrawn and less communicative. But at the same time, he would be very self - reliant and have a strong survival instinct.
His character would likely be a blend of his original self and the influence of the Madoka world. He would still be brave, but his understanding of good and evil might be more complex due to the different nature of the threats in the Madoka universe. For example, the witches are not like the Death Eaters. He might also become more empathetic towards those who are forced into difficult situations, like the magical girls.
