Well, he might be really confused at first. Camp Jupiter has its own set of rules and a very different culture compared to Hogwarts. He could struggle to fit in with the Roman demigods. Maybe his magic would be seen as something strange and new, and he'd have to prove himself all over again.
Some of the Roman gods or goddesses might also play important roles as characters. They could interact with Percy in different ways compared to how they interact with the Roman demigods in the camp. For instance, if Jupiter shows up, he might have different expectations of Percy compared to Poseidon, Percy's father in Greek mythology.
Perhaps Percy gets involved in a special mission at Camp Jupiter. Like he has to protect a powerful ancient artifact within the camp from an outside threat. This could involve a lot of action and strategy as he navigates the Roman camp's politics and military structure.
His powers would probably be seen as very strange. Magic isn't a common thing at Camp Jupiter. The demigods there are used to their own abilities like super strength or control over the elements. Harry's magic might seem like an otherworldly power that they don't quite understand.
He'd probably cause quite a stir. His wizarding abilities would be something new and exciting for the campers. They might be amazed when he pulls out his wand and does simple spells.
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.
Sure, there are. In these fanfictions, the idea of Harry being the son of Jupiter often leads to a whole new set of adventures. He may have to deal with both the wizarding world and the Roman mythological elements. His character might develop in different ways, perhaps becoming more confident in his powers which are now not just magic but also related to the might of Jupiter. And his enemies could also be different, maybe facing threats from both the magical and mythological realms.
Yes, there might be some. The idea of cross - over fanfiction like this is not uncommon. Writers often like to blend different fictional universes to create unique and interesting stories. However, the quality and availability can vary greatly. You may need to search on popular fanfiction websites.
