The normal humans in Forks would probably be very curious about this strange new boy. They might notice his odd behavior at times, like when he seems to be looking for something that isn't there or when he reacts strangely to certain situations that seem normal to them. If the Cullens were to notice him, they might be suspicious of his presence as he has an air of mystery about him.
The Cullens, being vampires themselves, would be interested in Harry's origin as a magically - turned vampire. They might want to learn more about his powers and how they could be useful or dangerous. Bella would likely approach Harry with an open mind, given her experiences with the Cullens. The werewolves, on the other hand, would be more territorial and might view Harry as an intruder until they get to know him better. His magic could make them even more on edge as they don't know what it's capable of.
The Cullens might be cautious at first. They have their own set of rules and way of life. If Harry Vampire shows up, they would need to figure out if he's a threat or not. They might try to keep an eye on him and see what his intentions are. However, if he proves to be harmless or even helpful, they could eventually accept him.
Some of the residents might be very curious. They would notice Harry and Hermione's different behavior and mannerisms. The more perceptive ones could sense that there is something special about them.
Hermione, on the other hand, would likely have a more critical view. She'd analyze the fanfictions for their accuracy in terms of magic lore and Hogwarts traditions. If there were any inaccuracies, she'd be quite perturbed. However, she might also appreciate the creativity that goes into some of the well - written ones that add new dimensions to their magical world.
The vampires in Forks would likely be both intrigued and cautious. They'd be interested in his unique vampire - ninja abilities but also worried about how his presence could disrupt their carefully maintained balance. The werewolves, on the other hand, might see him as a potential threat to their territory and way of life. However, if Naruto showed that he meant no harm and was actually there to help, some of the more open - minded characters, both human and non - human, could start to accept him and form relationships with him.
Some characters might be excited. They could see him as a new source of knowledge and magic.
The Weasley family would have different responses. Mrs. Weasley would be motherly and concerned about this strange new person. Fred and George would see her as a source of new ideas for their pranks and inventions. Ginny would look up to her as a strong female figure, much like she does with Hermione. And all of them together would gradually get used to having Powergirl around, and they would all grow from the experience of interacting with someone from a completely different world.
Batman would probably be very cautious at first. He'd want to study Harry and his magic to see if it could be a threat or an asset. The Joker might see Harry as a new plaything, a strange and magical being to toy with. Commissioner Gordon would likely be intrigued and hope that Harry could help clean up Gotham's streets.
Some characters might be quite amused. For example, Hermione would probably analyze the fanfiction from a logical perspective, critiquing the plotlines that involve ships. Ron, on the other hand, might be a bit bewildered at first but then find it rather entertaining. Harry himself could be either indifferent or intrigued, depending on how the ships are portrayed. If it's a ship that he has a personal connection to, like his parents, he might be more interested in seeing how the author has envisioned their relationship in the fanfiction world.
Dumbledore would likely be very accepting of Stitch. He has a great understanding of all kinds of creatures and beings. He would see Stitch's potential for good and might even try to find a place for him at Hogwarts. Snape, however, would be more skeptical. He would keep a close eye on Stitch, worried that he might disrupt the order of the school or cause harm to the students. The Weasley twins would probably find Stitch hilarious and would want to play pranks with him or use his unique abilities for their own mischievous plans.
