At first, Harry Potter would likely be taken aback. The X - Men universe is so foreign to his own magical realm. But as he delved into the fanfiction, he could start to enjoy it. He might laugh at some of the more humorous interpretations of the X - Men. He could also feel a sense of kinship with the characters as they face challenges and try to protect their own kind. He may even start to daydream about what it would be like if he had some of the X - Men's powers in addition to his magic, and how he could use them to fight Voldemort.
He'd probably be very curious. Harry has always been interested in new things, and this would be a whole new type of story for him.
Harry Potter might react with a mix of fascination and disbelief. On one hand, he would be drawn into the imaginative scenarios presented in the multiverse fanfiction. He might be excited to explore the different possibilities of his life and the lives of those around him. For instance, seeing a universe where Hagrid is a powerful wizard instead of a gamekeeper. On the other hand, some of the more outlandish ideas in the fanfiction might make him skeptical at first. But overall, he would likely be very interested in this new way of looking at his world and the magic within it.
Harry would be quite surprised at first. He'd be thrown into a world without magic, yet full of strong emotions and drama. He might feel a bit out of place, but as he gets into the story, he'd start to understand the human nature in it. He could admire the courage of the characters, like how they faced the disaster. And he might also be a bit confused by some of the muggle concepts like the class system on the ship.
He might be shocked. The fanfiction could show his friends or himself in situations that are completely different from what he knows. For instance, if it shows him losing to a minor villain, it would be very unexpected for him.
Harry might react with a sense of both curiosity and discomfort. The fanfic might have elements that are completely foreign to his understanding of his own story, yet he could also be intrigued by the creativity of it. He might start to wonder how much of his own life has been turned into something so different in the minds of others. He could also feel a bit protective of his own story and those of his friends, not wanting it to be misrepresented too much in the fanfic.
The fandom's reaction would be quite mixed. Some fans, who are more open to extreme and creative interpretations in fanfiction, might find it an interesting and bold take. However, the majority would probably be horrified. Snape is a beloved and complex character, and this idea of him being aroused by Harry fanfiction is so far from what J.K. Rowling created. It could lead to a big debate within the fandom about the limits of fan - created content and how it should respect the original source material.
He might be very surprised. The magical concepts are so different.
He could be shocked. Maybe there are some fanfictions that take a very dark turn or have unexpected pairings that he never thought of. He'd probably need some time to process such strange ideas. And he might also be curious to see how far the creativity of the fans can go. He might even get some new ideas about his own life from reading some of the more imaginative fanfictions.
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.
He might be amused. Harry has a sense of humor, and the often absurd and comical situations in Blackadder fanfiction could make him laugh.
