Things could have been very different in Harry Potter fanfiction. Maybe Voldemort was defeated earlier, or Harry chose a completely different career path after Hogwarts. Also, the relationships between characters could have taken unexpected turns.
Yes, it could have. Fanfiction often takes existing universes and expands or reimagines them. Harry Potter has so many elements that could potentially be the work of a fan. For example, the magical world with its unique creatures, spells, and Hogwarts as a school. If J.K. Rowling wasn't the original creator but was building on someone else's initial ideas about a magical school and a boy wizard, it would be fanfiction. However, she is the original creator, but the conceptually it has elements that could be seen in a fan - created work.
One possibility could be a world where Harry Potter takes on Voldemort's role in terms of power. The wizarding world would be in chaos as Harry, with his different values from Voldemort, tries to enforce his own version of order. He might use his knowledge of good magic in a twisted way, believing he is doing the right thing for the greater good. For example, he could start controlling the Ministry of Magic to implement changes he thinks are necessary, but which others may see as tyrannical.
The main difference would likely be the addition of kaiju - related plotlines. In the original stories, it's all about the wizarding world's internal politics and the fight against the Dark Lord. But in this fanfiction, there could be kaiju emerging from the Forbidden Forest, or some kind of kaiju - magic connection. For instance, a kaiju might be powered by dark magic that Harry has to stop. Also, the characters' interests and knowledge would expand to include kaiju lore, which is completely different from the traditional Hogwarts curriculum.
The story would likely be more light - hearted. For instance, the dark and gloomy parts of Hogwarts, like the Forbidden Forest, could be made to look less scary and more like a fun adventure area in a cartoon. The characters' appearances might change to be more cartoonish. Harry could have bigger, more expressive eyes and his hair could be even more unruly in a comical way.
The story would be different as Harry would have a new weapon. His combat approach would change. Instead of relying solely on spells, he could use Yamato for close - range combat. This would add a new layer of action to the story.
It could be a rewrite where Harry is raised by someone other than the Dursleys. For example, if he was raised by Sirius Black from the start, his whole outlook on magic and the wizarding world might be different. Sirius would have taught him about his family's noble history and perhaps some dark magic secrets earlier, which could change how Harry approaches challenges at Hogwarts.
Well, he might bake some butterbeer - flavored cookies. Since butterbeer is a popular drink in the Harry Potter world, it would be a great idea to turn it into a baked good. Also, he could bake owl - shaped pastries to feed his owl, Hedwig.
Some people might think so because of the common fantasy elements. It has things like a magical school, which is a staple in a lot of fantasy works. They may assume that it could be someone building on an existing idea in the genre, like fanfiction does. Also, the concept of a young hero coming of age in a special world is not new. So, they might see it as having the potential to be fan - created work within the broader fantasy framework.
In 'Harry Potter in a Different World Fanfiction', Harry might encounter new magical creatures. These could be creatures that are hybrids of the ones we know from the original series. He could also be part of a different magical society structure. Instead of Hogwarts being the main magical school, there could be a series of small magical academies scattered across the land, each with its own specialties.
It could be a story where the characters break the traditional Hogwarts norms. For example, instead of following the regular curriculum, students focus on a new form of magic that was previously ignored. This might change the relationships between different houses as they all work together towards this new magical discovery.
