What are some interesting storylines in Percy Jackson and Hunters fanfiction?

One interesting storyline could be Percy as a baby showing early signs of his demigod powers. Maybe he can control water in his crib, like making the bath water swirl around him in a mini - whirlpool. Another could be the reactions of the gods when they discover this new baby demigod. They might be worried about his potential or already planning how to use him in their future schemes.

There could also be a fanfiction where Percy has to face his inner demons in a more psychological way. Maybe he's haunted by the memories of all the battles he's fought and the friends he's lost. His friends then have to help him through this tough time, and in the process, they learn more about each other's deeper fears and insecurities.

One interesting storyline could be where Percy Jackson somehow ends up in Ariel's underwater world. Maybe he's on a quest that takes him there and he has to team up with Ariel to defeat a common enemy, like a sea monster that is threatening both the underwater kingdom and the surface world that Percy is from.

One interesting storyline could be a Futa Percy Jackson going on a new quest that involves saving a magical realm from an ancient evil. In this fanfiction, Percy's unique form might give her an edge in combat, like being able to use both male and female - like combat styles.

A really engaging storyline could be them being transported to a different era in the world of Greek mythology. They would have to adapt to the different rules and powers that exist in that time while still relying on their own abilities. This would put their friendship and skills to the test in a whole new and exciting way.

One interesting storyline could be a crossover where Percy Jackson meets the Crusaders in a modern-day setting.

Another could be Percy using his powers in a way that the Crusaders initially misunderstand, leading to some conflict before they realize they can work together.

One interesting storyline could be Percy's first encounter with a mythological creature as a kid but in a more humorous way. For example, he mistakes a satyr for a really hairy kid at school and tries to befriend it not knowing what it really is.

One interesting storyline could be Percy facing a new and powerful enemy that is a combination of Greek and some other mythologies' creatures. This enemy might be immune to his usual powers, forcing him to find new ways to fight.

One interesting storyline could be Percy and Zoe going on a secret quest together. They might face a new and unknown monster that is a threat to both the camps. Another could be a story where Zoe gets to show Percy some hidden parts of the magical world that he didn't know before.

A plot could revolve around Percy being falsely accused of stealing a powerful artifact from the Hunters. He then has to prove his innocence while also protecting the Hunters from those who really stole the artifact and are now using it to target the Hunters.
