Well, it could be really interesting. Harry Potter, with his magical background from Hogwarts, would find the world of Witchers quite fascinating. He might be intrigued by the Witchers' potions and their unique way of fighting monsters. Maybe he'd try to combine some of his spells with the Witchers' combat skills. For example, he could use a Patronus charm while also slashing at a monster with a Witcher's sword. And he'd surely be interested in the different kinds of monsters in the Witcher world compared to the ones he faced in the wizarding world.
If Harry Potter became a Witcher fan, the story would likely involve him traveling to the Witcher's world. There, he would meet Geralt and the other Witchers. Harry would be amazed by their skills and their no - nonsense attitude towards fighting evil. He might learn a great deal from them about handling different types of threats. And the Witchers, in turn, would be curious about Harry's magic. They could exchange knowledge, with Harry teaching them some basic spells and the Witchers showing him advanced combat techniques against monsters that are new to him.
The story could start with Harry finding a book about Witchers in the Hogwarts library. As he reads it, he becomes obsessed. He might start to train himself in the ways of a Witcher in secret. Since he's already good at magic, he could use magic to enhance his Witcher - like abilities. He could use magic to make his Witcher potions more effective or to help him track monsters more easily. His friends would be really confused at first, but as they see how dedicated he is, they might even join him in his newfound interest.
Well, he'd probably use his magic in a more Witcher - like way. Maybe he'd combine his Hogwarts spells with Witcher signs. For example, he could use Wingardium Leviosa along with the Aard sign to create a more powerful force push. He'd also have to deal with the monsters in the Witcher world using his new skills.
His friends would be very surprised. Hermione would probably be a bit skeptical at first. She'd want to research all about Witchers before she fully supported Harry's new interest. Ron, on the other hand, might be more excited. He'd see it as another adventure and would be eager to hear all about the Witcher world from Harry.
In such a fanfiction, Harry might gain the ability to rise from ashes, literally and metaphorically. He could have the power of regeneration and immortality like a Phoenix. This would change his battles, for example, he could fearlessly face Voldemort as he could always come back even if defeated. His relationship with his friends might also change. They would see him as an even more extraordinary being, and he might have to deal with their awe and a bit of distance that could come from his new form.
Well, if Harry Potter becomes a villain in fanfiction, it would be a complete subversion of the original story. He might use his powerful magic skills to dominate Hogwarts instead of protecting it. He could form alliances with the dark forces that he once fought against. Maybe he would start to spread fear among the students and teachers, and turn the school into a place full of chaos and tyranny.
A 'harry potter is a cowboy fanfiction' could be really wild. Picture Hogwarts as a big ranch in the middle of a prairie. The houses could be different barns or areas on the ranch. Spells could be used for things like herding magical cattle or protecting the ranch from dark wizards who are like bandits. The characters would have to learn both cowboy skills and magic, and there would be a whole new set of adventures and challenges for them.
Well, it could be really interesting. Maybe Harry discovers he has the ability to bend water like in the Avatar world. He could use it to his advantage during his battles at Hogwarts, creating water shields or using water to disarm his opponents in a very unique way.
In this fanfiction, we could see the Hogwarts castle being a place where Shazam - like powers are studied. The teachers might be trying to understand how these powers work alongside magic. For instance, Ron could accidentally get some of Shazam's powers and have to deal with the chaos that ensues. The story could also involve the villains from both worlds, like Voldemort teaming up with some of Shazam's enemies, creating a really complex and exciting plot.
If Harry Potter was raised by fanfiction, he could end up in a completely different Hogwarts. The fanfiction might rewrite the rules of the school, so he could be part of a new house system or have different classes. His friendships might also be altered. For example, he could be closer to some minor characters from the original series, and they could go on adventures that are more in line with the wild ideas often found in fanfiction.
In a 'Harry Potter is a Mandalorian fanfiction', we could see Harry Potter wearing Mandalorian armor while still being able to use his magic. He could be on a quest similar to the Mandalorian's, like protecting a youngling. The story could blend the magical elements of Harry Potter, like potions and spells, with the technological and action - packed world of The Mandalorian. For example, Harry could use a spell to enhance the Mandalorian's blaster or use a potion to heal an injured alien. There would be a lot of potential for character development as Harry adapts to this new and very different universe.
A 'harry potter is a xenomorph fanfiction' could involve the Xenomorphs infiltrating the wizarding world. The Ministry of Magic would have to deal with this new threat. Harry and his friends could be on a quest to find a way to stop the Xenomorphs from spreading, perhaps using some ancient magic that has been long forgotten. There could be a lot of action and suspense as the wizards try to understand the alien biology and weaknesses while the Xenomorphs keep attacking. The story could also explore how the different houses in Hogwarts cooperate or compete in this crisis situation.
