The consequences could be quite complex. Firstly, there's the physical aspect. He could experience intense pain during the transformation process, which might be a regular occurrence depending on the rules of the werewolf lore in this fanfiction. Emotionally, he might struggle with his identity. Is he still Naruto the ninja, or is he now something else? This internal conflict could lead to some interesting character development. Socially, his relationships might change. Some of his friends might be afraid of him, while others might be intrigued and want to help him. And from a plot perspective, this new development could lead to all sorts of adventures, like seeking a cure or finding others like him.
The consequences could be far - reaching. Naruto's relationships would surely be strained. His relationship with Sakura, for instance, might become complicated as she may be afraid of him or try to find a way to cure him. His bond with Sasuke could also be tested. Sasuke, being more attuned to darker powers, might have a different reaction compared to others. Moreover, Naruto would have to deal with the vampire community if there is one in the fanfiction world. He would need to learn their rules and how to control his new urges, or else he could become a danger to those he loves.
Well, in the fanfiction, being bitten by a female vampire might lead to Naruto being drawn into the vampire world. He could be forced to deal with vampire politics and hierarchies. It might also create a conflict within him as he tries to balance his ninja life with this new, unexpected vampire side. For example, he might have to hide his new condition from his friends like Sasuke and Sakura at first.
Well, it could lead to her being ostracized by some in the wizarding community. People might fear her new werewolf nature, just like they did with Lupin. This could make her feel isolated and struggle with her identity. She might also have to learn to control her newfound instincts, which would be a huge challenge.
Sasuke might be initially suspicious and keep his distance. He's always been cautious, and this strange new development would make him even more so.
Naruko might also gain some vampire - like powers. For example, she could have increased speed and strength. However, she would also have to face the negative aspects. Vampires are often hunted or feared in many fanfictions. So she would have to constantly be on the lookout for those who would do her harm, and she would have to learn how to control her new vampire nature so as not to attract unwanted attention.
The bite might also change her appearance. She could develop paler skin, more prominent fangs, and a more alluring yet slightly menacing look. Her magic could be affected too. It might become intertwined with her new vampire nature, resulting in some unique and unpredictable magical effects that she would have to learn to control.
It could be the werewolf who bit Harry. Maybe the werewolf has some ulterior motives, like using Harry as a pawn in a bigger plan against the wizarding world. Or it could be some pure - blood wizard supremacists who see Harry's new werewolf status as a sign that he is now 'impure' and want to get rid of him.
Well, Kakashi is a very skilled ninja. If Naruto were to pickpocket him in fanfiction, he'd likely get caught right away. Kakashi has his Sharingan which can detect movements easily. And even if Naruto managed to steal something, Kakashi would probably figure it out quickly and Naruto would be in big trouble for disrespecting his sensei.
The consequence could be that the fanfiction community might feel less connected to Minato as a character. Since he is a significant part of the Naruto universe, his dislike of fanfiction could make some fans less enthusiastic about including him in their fan - created stories. This might lead to a shift in the focus of fanfiction towards other characters who are more 'welcoming' of fan interpretations.
If Naruto fails the academy in fanfiction, he might face a lot of disappointment from the villagers. They already look down on him, and this could make it worse. He might also lose confidence in himself and his dream of becoming Hokage could seem even more out of reach.
