A new character could be a transfer student from another demigod camp. This student has a different set of powers and a unique backstory related to a less - known Greek god. They could initially clash with Percy but then become great friends as they face challenges together.
One idea could be Percy having to deal with a new bully at middle school who turns out to be a minor monster in disguise. He has to figure out how to expose the bully without revealing his own identity as a demigod to the regular students.
The Percy Jackson school reunion was a chaotic yet heartwarming affair. Percy and Annabeth arrived late, having been held up by some minor sea monster issue on the way. Once there, they were greeted by a sea of familiar faces. Clarisse was showing off her new battle scars, much to the amusement of the others. Tyson, Percy's cyclops half - brother, had brought some amazing underwater treats. Everyone took turns sharing their post - school adventures, from building new cabins at Camp Half - Blood to exploring ancient ruins in search of more demigod lore.
Well, he might be really confused at first. Middle Earth has its own rules, magic, and races. Percy, with his water powers, could have some interesting interactions with the rivers and seas in Middle Earth. Maybe he'd help the Fellowship in some way, like using his powers to create distractions during battles or to cross dangerous water areas.
One great Percy Jackson high school fanfiction is 'New Beginnings at Goode High'. It shows Percy trying to fit into a normal high school life while still having his demigod secrets. The author does a great job of portraying the internal struggle Percy faces between his two worlds.
One great Percy Jackson fanfiction set in a high school could be 'High School Demigods'. It really captures the essence of the characters in a modern high school setting. The author does a wonderful job of bringing in the elements of the Percy Jackson world, like the different cabins and powers, into the school environment.
Friendship is a very common theme. In middle school, Percy and Annabeth are starting to build a bond. Their different personalities - Percy's more laid - back and Annabeth's more studious - make for an interesting dynamic as friends.
A rather unique fanfiction in this category is 'Percy's Hidden School Life'. This one focuses on Percy's attempts to keep his demigod life a secret while also dealing with being considered a loser at school. It has some great character development as Percy tries to balance his two worlds and gradually gains the respect of his classmates through his own merits, not just his powers.
I really like 'Percy Jackson: High School Years'. In this fanfiction, the author does a wonderful job of integrating the mythology from the original series into the high - school environment. For example, the monsters become the bullies in the school, and the quests are like school projects with a life - or - death twist. It's a fresh take on the Percy Jackson world.
Percy himself is obviously very popular. His charm and his abilities as a demigod make him a central figure. Annabeth is also often included. Her intelligence and strategic thinking can play a great role in the royalty school setting. Another popular character could be Nico. His dark and mysterious nature adds an interesting element to the story.
