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.
In a fanfiction, the interaction would be full of surprises. Harry Potter and his friends would bring their own set of values and skills. Harry's sense of justice would align well with the demigods' heroic nature. Hermione would be like a walking encyclopedia, impressing the demigods with her vast knowledge. The demigods could teach the Harry Potter characters about their unique powers. Percy Jackson might show Harry how to control water in a different way than magic. There could also be some misunderstandings at first. For instance, when Harry first uses magic, the demigods might think it's some kind of dark power. But as they get to know each other better, they would form strong alliances and friendships.
Harry Potter could fit into Camp Half - Blood in a fanfic by showing his loyalty and friendship skills. He's known for being a great friend at Hogwarts, and those qualities would be useful at the camp too. Also, his magical abilities, though different from the demigods', could be an asset in certain situations, like when they need to solve a mystery or overcome an obstacle.
There would also be those who are angry. Some of the campers who have always been a bit jealous of Percy's status might think he's just being selfish or irresponsible. But deep down, they'd also be a bit concerned for his well - being, even if they don't show it at first.
Well, he might be really confused at first. The magic in the Camp Half - Blood is different from what he's used to at Hogwarts. He could make some new friends, like the demigods there. Maybe he'd learn new combat skills too.
Gabe would probably be very intimidated at first. Demigods have powers and abilities that are far beyond what he's used to. He might act tough at the start to hide his fear, but as he sees more of what they can do, he could become more submissive or try to make friends with them out of self - preservation.
If Harry Potter was raised in Camp Half - Blood, he would likely be trained in a different way of magic. The demigod training there focuses on physical combat as well as magic use. He might have an easier time with some magical creatures that are common in the Greek mythology world of Camp Half - Blood compared to the ones in the wizarding world. His wand might not be as crucial as it is in the wizarding world, since demigods rely more on their inborn powers.
Well, he might be really confused at first. Camp Half - Blood is so different from Hogwarts. He'd see all the Greek mythology stuff which is new to him. Maybe he'd try to compare the magic there with his own. He could also make new friends, but might have some clashes with the demigods because of his different magical upbringing.
Another theme is the discovery of new magic. With the merging of two different magical concepts, fanfiction often features characters exploring new forms of magic that are unique to this combined universe. For example, spells that are a combination of Hogwarts magic and the powers of the demigods. This makes the stories exciting as readers get to see something new and different.
Yes, there are quite a few. You can find them on various fanfic websites. Some might focus on crossovers between the two universes, like a character from Harry Potter ending up at Camp Half - Blood and having to adapt to the new environment and its rules.
Reyna from Camp Jupiter would also be a great character to focus on. She's strong, intelligent, and has a lot of leadership experience. In a fanfiction where the two camps meet, she could represent the Roman side well, and her interactions with the Greek demigods would be full of potential for conflict and cooperation. For example, she might initially be skeptical of the more laid - back Greek approach to things, but come to appreciate it as they work together.
