Perhaps it could be a centaur who was once a great guardian of the forest but has been broken by the encroachment of dark forces.

One possible plotline could be Percy having to deal with broken bones during a quest. Maybe he gets injured while fighting a monster and has to find a way to continue the mission with his injury. Another could be that his broken bones are the result of a prank gone wrong by one of the other campers, leading to some comical and tense situations at Camp Half - Blood.
It could be a new, powerful monster. Maybe a giant with the ability to shatter bones just by looking at a person. This monster could be targeting Percy specifically because of his reputation as a hero among the demigods.
In 'Percy Jackson Broken Hero Fanfiction', an interesting concept could be Percy's isolation as a broken hero. He might be physically or emotionally separated from his usual support system. This isolation could force him to rely solely on himself, which is a big change from his normal reliance on his friends. It could also show his journey of self - discovery in this new, more solitary state, and how he might come out stronger in the end despite the initial 'broken' state.
There could be a healer character. Since Percy is a broken hero, someone with the power to heal his physical or emotional wounds might be introduced. This character could have their own backstory and motives, perhaps being related to an ancient Greek deity of healing in a new and unique way.
