Hermione would probably be both curious and worried. She'd want to research all about Harry's half - demon nature to find out what it means and how to help him. Ron, on the other hand, might be a bit more hesitant at first. He might be a bit scared but would eventually come around because of his loyalty to Harry.
The other students at Hogwarts would have a mixed reaction. Some, like Neville, might be sympathetic and try to befriend Harry even more. Others, especially those from pure - blood families with more traditional views, could be quite hostile. The teachers, for the most part, would probably try to keep an eye on Harry to make sure his demon side doesn't cause any problems. But they would also be interested in seeing how his unique nature could be an asset in the fight against dark magic.
I'm not entirely sure if there is a specific 'Harry Potter is half demon' fanfiction, but considering the limitless creativity in the fanfiction community, it's very likely. Writers might be inspired to create such a story to explore the contrast between the magical world of Harry Potter and the more dark and otherworldly concept of being half - demon. They could use it to examine themes like acceptance, identity, and power in a whole new light.
Often, Harry Potter himself can be a main character in these fanfictions, where his character might be reimagined in some way due to the presence of the half - demon element. For example, he could befriend or be in conflict with the half - demon character.
Harry's relationship with his enemies would also be different. Voldemort might see him as a more formidable opponent due to his dual nature. He might try to turn Harry's demonic side against the wizarding world. On the other hand, Harry's angelic side could make some of the Death Eaters question their loyalty to Voldemort as they see a glimmer of hope in Harry. Overall, his relationships would be in a state of flux as he tries to navigate his new identity and the reactions of those around 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.
Well, perhaps the plot could involve Harry struggling with his new - found half - demon nature. He might have to hide it from his friends at Hogwarts for fear of being ostracized. And he could discover that his demon side gives him some unique magical abilities that are both a curse and a gift.
One great fanfiction in this category could be 'The Half - Demon's Journey at Hogwarts'. It delves into Harry's new identity as a half - demon while still maintaining his connection to Hogwarts and Dumbledore's guidance. Dumbledore, being the good and wise figure, helps Harry navigate his new powers and the challenges that come with it, like dealing with the wizarding world's reaction to his unique nature.
One possible plot could be that Harry discovers his half - demon heritage as he grows older. He might face discrimination from some in the wizarding world who fear his demon side. He then has to go on a journey to learn about his demon heritage and how to control the powers that come with it, all while still fighting against Voldemort or other threats in the wizarding world.
Some would be very curious. They've probably never seen someone like Harry before. Others might be a bit skeptical, wondering what his intentions are.
The Death Eaters and their sympathizers would be terrified. Harry, as the overlord, would be a major threat to their ideology. Voldemort, if he somehow still existed in this fanfiction, would be in direct opposition to Harry. However, some of the more neutral characters, like Luna, would probably see Harry's new role as an opportunity for positive change in the wizarding world and would be happy to support him in his endeavors.
Well, if Harry turns into a cat, Hagrid would be quite worried. He might try to take care of Harry in his cat form, giving him treats and a warm place to sleep. The other students would have a mix of reactions. Some might be scared, thinking it's some sort of dark magic at work. But his closer friends like Neville would be determined to help. Neville might even try some of his own plant - based magic to see if it could help Harry turn back. Snape, of course, would probably be skeptical and think Harry got himself into this mess on purpose.
