Percy might encounter Baba Yaga. She is a well - known figure in Russian folklore. She could be an adversary, testing Percy's skills and his knowledge of the magical world. Or perhaps she could be a source of information if Percy manages to earn her respect. He could also meet the Rusalki, water nymphs from Russian mythology. Given Percy's connection to water, it would be interesting to see how he interacts with them.
Well, perhaps in this fanfiction, Percy moves to Russia because there's a threat emerging from an ancient Russian magic source. The story could involve him making new friends in Russia who help him understand their local mythology better. He might get involved in a battle against a powerful Russian sorcerer who is misusing the power of the gods. Percy would use his skills with water, his sword, and his wits to stop the sorcerer and save the day.
He could be friends with Neville. Neville is kind - hearted and they might bond over their shared experiences of feeling a bit out of place at Hogwarts. Another friend could be Luna. She has an open - minded and unique personality, and she would likely accept Percy for who he is.
It could be a demigod who was overshadowed by the more well - known ones like Percy. Maybe someone who was born to a minor god or goddess and got lost in the shuffle. For example, a demigod of a nature god who was always in the background while the big battles were fought by the children of the more prominent Olympians.
Well, perhaps Percy could be a new student at Hogwarts. He might face challenges like making friends in a new and magical environment. Maybe he gets sorted into a house and has to learn to fit in with his new housemates. He could also discover some hidden secrets about Hogwarts that are not known to many.
Maybe Percy will face new challenges in college like dealing with difficult classes. He could also meet new friends or enemies. And perhaps he'll discover new powers or secrets related to his special nature.
There could be a school janitor who is actually an old demigod who retired from the hero business. He could give Percy some valuable advice based on his own experiences. And of course, Percy will surely meet Annabeth's classmates, some of whom could be friendly and some not so much, depending on how they react to the new boy in school.
Percy Jackson is likely to still be one of the main characters. Since it's related to his world, he'd be in the center of the story. Alongside him, there could be new characters representing the forgotten primordial beings. They might be ancient and powerful, with names and abilities that are unique to this fanfiction realm.
