The story would likely progress in a very different direction. Harry would no longer be just a wizard. His new vampire nature would make him an outcast in many ways. He might be hunted by some in the wizarding community who see vampires as a threat. At the same time, he could meet other vampires who have different motives. Some might want to use him for his connection to the wizarding world, while others might want to help him. His journey would be one of self - discovery, trying to balance his two natures and figure out where he belongs in this new and complex situation. He would also have to deal with the fact that his lifespan might be greatly extended, which would change his perspective on life and his future plans.
In fanfiction, if Harry Potter were bitten by a vampire, he might gain some vampire - like abilities. For example, he could have enhanced strength and speed. His magical abilities might also be affected, perhaps enhanced in some strange ways or combined with his new vampiric nature. However, he would also face the challenges that come with being a vampire, like the need to feed on blood. This could create a whole new set of moral and ethical dilemmas for him, as he is a hero who has always fought for good. And his relationships with his friends at Hogwarts would surely be put to the test as they try to come to terms with his new state.
The plot would change in many ways. Harry being bitten by a vampire means he'd have different needs and abilities. His magical training at Hogwarts might be put on hold as he tries to understand and control his vampiric instincts. He could form alliances with unexpected characters, perhaps other vampires who oppose the dark wizards. His journey would become more about self - discovery and finding a balance between his wizard and vampire sides. The existing conflicts in the story, like the war against Voldemort, would be intertwined with his new situation. For example, Voldemort might try to use Harry's new nature against him, or Harry could use his vampire powers to gain an advantage in the fight.
Well, the story might progress as Harry struggles to control his new vampire instincts while still fighting against the dark forces in the wizarding world. He could form an alliance with some vampires who are on the good side, if there are any. This would give him access to new powers and knowledge. Meanwhile, Voldemort or other dark wizards might try to use his new condition against him. For example, they could try to frame him for attacks on other wizards so that the wizarding community turns against him.
There could be a whole new plotline involving the werewolf packs. Maybe Fenrir Greyback had a specific reason for biting Hermione, and his pack might be involved in some grander scheme. Hermione could be caught in the middle of a werewolf power struggle, having to decide which side to take or how to use her new position within the werewolf community to bring about peace or change.
The story could progress with Harry trying to find a way to turn back. He might search for ancient spells or magical artifacts that could reverse his condition. His friends would be desperate to help him, and they'd start their own investigations. Maybe Hermione would scour the library for any information on wraiths and how to reverse the transformation.
The story could progress with Harry exploring his new powers. He might start by accidently using them in the wizarding world and causing a stir. Then, he would have to figure out how to control them.
In the beginning, Batman would instill in Harry a sense of vigilance and a desire to protect the innocent. As Harry enters the wizarding world, he'd be an outlier. He might face some resistance from the more traditional wizards. But he'd also introduce new ideas. For example, he could suggest a more organized approach to fighting the dark forces, similar to Batman's methods. His relationships with the teachers would also be unique. Some might admire his different perspective, while others might be skeptical. As the story unfolds, Harry would likely be at the center of a clash between the old ways of the wizarding world and his new - age ideas influenced by Batman.
The story could start with Harry finding Naruto in some sort of strange situation, like he accidentally gets transported to the wizarding world. Then Harry decides to take Naruto under his wing. As they spend time together, Naruto would start to learn about magic, and Harry would learn about Naruto's ninja skills. Their friendship would grow, and they would face various challenges together. Maybe they would have to deal with a dark wizard who is interested in Naruto's unique abilities. And along the way, Naruto would make friends with other Hogwarts students, like Neville, and they would all learn from each other.
At the start, Harry would likely be cautious around the kitsune. But as he realizes it's not a threat, he'd start to explore what it can do. They might start by communicating, which could be difficult as they come from different magical systems. As time goes on, they could discover that their magical abilities can complement each other. For instance, the kitsune's agility and shape - shifting could help Harry in some of his adventures. And Harry's knowledge of spells could be useful to the kitsune in new situations.
