One possible fanfic could be about Percy and Annabeth facing a new mystery in high school. Maybe there's a strange teacher who seems to know more about their demigod past than they're comfortable with. Percy could be struggling with his ADHD in the academic setting, and Annabeth is constantly helping him study while also trying to solve the mystery of the teacher.
A high school fanfic for Percy and Annabeth might involve them in a school project. They are paired with some not - so - friendly classmates. Percy's natural leadership and Annabeth's intelligence come into play. They start to notice some odd things about the school building during their research for the project, like hidden passages that might lead to something related to their demigod heritage.
They could participate in a school sports event. Percy, with his natural athleticism, would be great at swimming or track. Annabeth might be more into something like debate team or chess club. But then a rival school turns out to have some sort of demigod - related threat, and they have to work together to overcome it while still trying to win the sports event or the club competition.
Another way is through the intervention of their friends. Their mutual friends could bring them together and encourage them to see things from the other's perspective. The friends can share stories about how each of them is really a good person deep down. This might soften their hearts towards each other.
One idea could be that Percy and Annabeth are new students at a high school filled with mythological secrets. They have to hide their demigod status while also dealing with normal high school problems like exams and bullies. Maybe they join the school's swim team and debate club respectively, which could lead to some interesting interactions.
Percy could meet the school bullies. And they might pick on him at first, but then be in for a big surprise when he shows his strength. Also, he might encounter some teachers who suspect there's something different about him. Maybe a science teacher who notices his quick reflexes during an experiment or a history teacher who is amazed by his knowledge of ancient mythology.
Maybe she's jealous of Percy's popularity at school. It could be that he always gets more attention, whether it's from teachers or other students.
One idea could be that they compete in various school competitions like academic decathlon or sports events, always trying to outdo each other. For example, in a science fair, Percy might do a project on underwater ecosystems because of his love for the water, while Annabeth does something related to architecture. Their rivalry makes them both push harder and come up with more creative ideas.
They could be involved in a high school project that turns out to be related to an ancient prophecy. Percy might use his water - controlling abilities in a science experiment in a really cool and unexpected way, and Annabeth would be there to explain the historical context behind it all.
There's Tyson, Percy's cyclops half - brother. In high school fanfiction, he can be really endearing as the big, strong but gentle guy. He might be on the school football team or something similar. And then there's Rachel Elizabeth Dare. She could be the artsy girl in school who has a bit of a crush on Percy and causes some jealousy with Annabeth, adding some romantic tension to the story.
Maybe Percy would struggle to fit in at first. He's used to his own world and suddenly being in a regular high school could be quite a shock.
Grover would be a great addition. He could be the quirky sidekick in the high school setting, always getting into comical situations while also providing some sage advice to Annabeth and Percy based on his own experiences. For example, he could help Percy figure out how to ask Annabeth to the prom.
