In this fanfiction, the interactions would be full of tension. Harry would be like a fish out of water in Arkham. The villains in Arkham, such as the Joker or Harley Quinn, could have very different reactions to Harry. The Joker might see him as a new plaything to toy with, while Harley Quinn might show some sympathy towards him. And Harry would have to constantly navigate these dangerous relationships while also trying to figure out his own identity in this strange new world.
Sam and Dean Winchester would interact with Harry like a big brother - type relationship. They would be protective of him, and teach him things. For example, Dean might show Harry how to use a gun while Sam could help him with research, both magical and non - magical. Harry would likely share his knowledge of magic with them, which would be fascinating for the Winchesters. He could also introduce them to his friends from Hogwarts like Hermione and Ron, and there would be some interesting cultural clashes between the hunter and wizarding cultures.
The interactions would be really fascinating. Harry could introduce his Hogwarts friends to things like the Ninja Way. Hermione would probably analyze it from a theoretical perspective, while Ron would be more interested in the practical side, like any new spells or skills. The teachers at Hogwarts would also have to adapt to Harry's different approach. For example, Snape might be even more critical at first, but as he sees the positive aspects of Harry's Naruto - influenced growth, he might change his view slightly.
Definitely Sam and Dean Winchester. They would be like his surrogate brothers or mentors. Then there's Castiel, the angel. He could have some interesting interactions with Harry, perhaps being intrigued by his magic. Bobby Singer could also be there, guiding Harry in the ways of hunting.
Well, in such a fanfiction, Harry would likely face a lot of challenges different from his original story. He'd be exposed to the insanity and chaos of Arkham. His Hogwarts - like education might be replaced with learning to survive in a place full of villains. He could potentially develop a very different set of skills and a much more cynical view of the world.
Well, Harry would be much more aloof and menacing. He might not interact with Hermione and Ron in a friendly way at all. Instead, he could view them as potential sacrifices or just insignificant beings. Hermione, being the intelligent one, might be terrified of Harry's newfound powers and strange upbringing. Ron would probably be outright hostile towards Harry, seeing him as a threat to the normal wizarding way of life.
The main characters in 'Harry Potter raised by Winchesters' fanfiction would have some interesting interactions. Harry would surely have a lot of interaction with the Winchesters' enemies as well. Demons and other supernatural beings that the Winchesters fight would see Harry as a new target or a strange addition to the mix. In the wizarding world, Harry might interact with Snape in a more confrontational way, as his upbringing by the Winchesters could make him less patient with Snape's attitude. Also, new characters from the cross - over of the two universes could be created, and Harry would be at the center of those interactions.
Well, he'd probably be exposed to a lot of chaos and madness. He might develop some very different magical skills, perhaps ones influenced by the dark and deranged atmosphere of Arkham. He could also have a very warped view of the wizarding world compared to what we know from the original series.
The younger Gallagher kids like Carl and Debbie would probably see Harry as a cool older brother figure with amazing powers. They'd constantly be asking him to do magic tricks for them. And Harry, having grown up without much of a family, would likely enjoy the attention and the sense of belonging in this big, chaotic family. Meanwhile, Frank might try to take advantage of Harry's magic for his own selfish reasons, which could lead to some interesting conflicts within the family.
One of the main characters would likely be Death itself, who could take on different forms and interact with Harry throughout his life. Dumbledore would also be an important character as he tries to understand and guide Harry, despite his unusual upbringing. And then there are Harry's friends like Hermione and Ron, who would have to adjust to Harry's different perspective on life and magic due to his being raised by Death.
The characters would have a different set of skills to show off. For instance, Harry could use his Yu Yu Hakusho - inspired powers to impress his friends. Ron might be a bit more envious and try to learn from Harry. Hermione would probably analyze how these new powers fit into the existing magical knowledge.
