The plot could change drastically. Harry might become more paranoid about the unknown threats in his world. He could start seeing potential Lovecraftian - like entities in the Forbidden Forest or in the shadows of Hogwarts. This new - found fear could make him more hesitant in his adventures and less likely to jump into dangerous situations without more information.
If Harry Potter reads Lovecraft fanfiction, the plot might take a turn towards a darker and more philosophical direction. He could start to question the very nature of good and evil in his world. Since Lovecraft's works often deal with the idea that there are forces beyond human understanding that are neither good nor bad in the traditional sense. Harry might then view Voldemort as just a small part of a much larger and more terrifying unknown. This could lead to him trying to find a different way to deal with threats in his world, perhaps one that involves more study of the ancient and arcane rather than just using spells and magic he already knows.
Well, Harry Potter might be really confused at first. Lovecraft's works are full of cosmic horror and a very different kind of magic compared to the magic in the wizarding world of Harry Potter. He would probably be shocked by the dark and often nihilistic themes in Lovecraft's fanfiction.
James Potter's perspective would likely change in several ways. He might gain a new appreciation for how his story has inspired others. He could also become more aware of the parts of his life that people find most interesting. For instance, if fanfiction often focuses on his time at Hogwarts, he might start to think more about those days and how they shaped him. At the same time, he might be a bit dismayed if the fanfiction misrepresents him or his friends. This could make him more determined to set the record straight about certain events.
He might feel a bit embarrassed. After all, these are often people's wild imaginings about his personal life.
If Harry Potter reads wuxia fanfiction, his view of magic could be revolutionized. He is used to a system where magic is taught in a formal way at Hogwarts. However, wuxia presents magic as something that can be self - cultivated through discipline and training. He may start to think that there are other ways to develop his magic power, not just relying on textbooks and teachers. Also, the way wuxia characters use magic for justice and to protect the weak might make him reevaluate his own purpose in using magic. He may become more eager to use his magic for the greater good in a more hands - on and self - reliant way.
The plot would change in many ways. Harry being bitten by a vampire means he'd have different needs and abilities. His magical training at Hogwarts might be put on hold as he tries to understand and control his vampiric instincts. He could form alliances with unexpected characters, perhaps other vampires who oppose the dark wizards. His journey would become more about self - discovery and finding a balance between his wizard and vampire sides. The existing conflicts in the story, like the war against Voldemort, would be intertwined with his new situation. For example, Voldemort might try to use Harry's new nature against him, or Harry could use his vampire powers to gain an advantage in the fight.
His view of magic might become more expansive. He'd see that magic can be used in ways he never imagined. For example, the way Fairy Tail mages use their magic for non - academic purposes like building things or creating shows. It could make him think about the practical applications of magic beyond just fighting dark wizards.
Dumbledore could gain new insights. Fanfiction might explore the social aspects of the wizarding world in ways he hadn't considered. Maybe there are stories about how the different houses interact in a more complex way than he thought. This could make him reevaluate his own views on the unity or division within Hogwarts.
Harry Potter's view on heroism might shift. In Fate Stay Night, the heroes have different backstories and goals. After reading the fanfiction, Harry could start to think about how his own heroism is defined not just by his fight against Voldemort but also by his relationships and the choices he makes in general. He might also see that heroes can come from different places and times, not just the wizarding world he knows.
He might be surprised. The Harry Potter world has its own set of rules and characters that are very different from what Merlin is used to in his Arthurian world.
The plot would be much more complex. Harry could easily defeat Voldemort with the combined power of the Infinity Stones. So the main conflict of the original story would be resolved very quickly.
