When Harry Potter arrives in Storybrooke in fanfiction, it would cause quite a stir. Belle, being a lover of books, would be fascinated by the stories of the wizarding world that Harry could tell. Rumpelstiltskin, on the other hand, would be calculating. He'd be thinking about how he could use Harry's presence to his advantage, whether it's trading magic or getting information. The townsfolk in general would be a mix of awe, suspicion, and excitement. They're not used to strangers from such different magical backgrounds, so it would take time for them to fully accept Harry.
Some characters in Storybrooke might be very curious about Harry. For example, Henry would probably be excited to have someone new with such a different magical background. Regina might be a bit suspicious at first, as she's used to being in control. But she could also see the potential in Harry and his abilities. The Charmings would likely welcome him with open arms, seeing him as another person to help protect the town.
Some might be curious about him and his magic. Others could be a bit wary, thinking he might bring trouble. But there would probably be a few who would be excited to learn from him.
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.
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.
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.
Draco Malfoy would probably be outraged at first if he read fanfiction that showed him in a positive light towards Harry and his friends. He's so used to being on the opposite side, but then he might secretly be a bit flattered by some of the more complex characterizations of him.
In a fanfiction, the students at Hogwarts would be really intrigued by Hawkeye. They've grown up in a world of magic, and Hawkeye would represent a different kind of power. Neville might look up to Hawkeye as someone who uses their own skills to fight, without relying on magic. Ginny would probably be eager to team up with Hawkeye in any battles or adventures, seeing his potential as an ally in the fight against evil.
Hermione would probably be very curious about Darkseid at first. She'd try to research him in the Hogwarts library, looking for any clues about his powers and weaknesses. But once she realizes the danger he poses, she'd be quick to come up with strategies to fight him.
