A really interesting plot would be if Percy's friends from Camp Half - Blood transfer to Goode High for some reason. They all have to adapt to the mortal school life while also dealing with the threats that follow Percy, like a vengeful demigod from an enemy camp who wants to expose Percy in the middle of his mortal school life.
One idea could be Percy having to deal with a new type of mythical creature that has infiltrated Goode High School. Maybe a group of mischievous satyrs that are causing chaos in the school cafeteria by stealing all the food and Percy has to use his skills to stop them without revealing his true identity to the normal students.
Well, a cool plot might involve Percy's old enemies from the demigod world somehow influencing events at Goode. For example, a spell is cast that makes the students act like the minions of an ancient Greek villain. Percy then has to figure out how to break the spell without revealing his powers too much. Also, it could be interesting if there was a plot where Percy discovers a hidden part of Goode that has a connection to the gods, like a secret chamber that was built long ago by a demigod who attended the school.
Well, one possibility is that they face challenges related to hiding their demigod identities while trying to fit in at a normal high school. Maybe Percy has trouble in a swimming class because his powers make him too good and he has to hold back. Annabeth could be acing all her academic classes but struggle with the social drama that comes with high school.
Maybe in this high school fanfiction, Percy is on the swim team and Calypso is the manager. There's a big competition coming up and they have to work together to make sure the team is ready. Along the way, they develop feelings. Calypso helps Percy deal with his insecurities about the competition, and Percy shows Calypso that there's more to life than just being popular.
One idea could be Percy trying to hide his demigod powers from his high school classmates while still using them to solve normal high school problems like bullying. Another could be Percy forming a secret club in school for other kids with special abilities. Or maybe Percy getting into a friendly rivalry with the school's star athlete in a non - combat - related sport like track and field.
One idea could be a high school talent show where Annabeth and Percy team up for a project that combines Annabeth's strategic mind and Percy's natural athleticism. They could create a unique performance that showcases both their skills and also their growing relationship.
Well, it could be about their adventures in Goode High. Maybe they're facing some new mythical creatures that are lurking around the school. They might be trying to keep their demigod identities a secret while also dealing with normal high school stuff like exams and making friends.
Perhaps there's a prophecy that involves both Percy and Artemis in the high school. It could be about a hidden power within the school that only they can unlock together. They have to navigate high school politics, friendships, and enemies all while trying to figure out the prophecy and save the day.
One idea could be Percy having to hide his demigod powers at high school while dealing with a bully who unknowingly has ties to a minor Greek god. This would create a lot of tense drama situations.
Perhaps there's a mystery at Ares High School where strange things keep happening, like students getting sudden bursts of uncontrollable strength. Percy, suspecting it has something to do with Ares, investigates and discovers an ancient artifact hidden on campus that's causing the chaos. He then has to find a way to stop it without getting caught by the school authorities or Ares' minions.
