Maybe Percy breaks his ribs in a training accident at Camp Half - Blood. This could lead to him feeling frustrated as he can't participate fully in activities. He could then discover a new way to train or gain power while recovering, perhaps by learning more about his demigod heritage in a different way.
In the fanfiction, Percy could break his ribs while on a quest. His injury would make the quest even more dangerous. He'd struggle with pain but still be determined to complete the mission. His friends would be worried about him, and there could be moments where they debate whether to continue or find a safe place for Percy to heal.
Percy might become more empathetic. Since he's usually the strong one, being injured would make him understand what it's like for others who are hurt. He could develop more patience as he has to wait for his ribs to heal.
The plot could involve Percy having an accident during a battle. Maybe he's fighting a powerful monster and gets thrown against a hard surface, resulting in broken ribs. His friends then have to figure out how to get him medical help in the middle of their adventure.
Well, it could be about a guardian figure in the Percy Jackson world who has been broken in some way. Maybe a protector who has failed in their duty, or perhaps has had their spirit or power broken. It might explore their journey to redemption or how their broken state affects the other characters around them.
One consequence could be Percy feeling betrayed. He has always been a hero for the gods, but if they keep breaking their promises, he might lose faith in them. This could lead to him distancing himself from the world of the gods and focusing more on his own life or the lives of his mortal friends.
Well, one possibility could be a story where Percy Jackson, with his demigod powers, somehow stumbles into Morathi's realm. Maybe he initially mistakes her for an ally, but soon discovers her true nature. And they could be forced to work together against a common enemy, like a new, powerful ancient evil that threatens both their worlds.
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. Or it could be a minor god who was supposed to protect a certain aspect of the world but has failed and is now in a broken state. There are many possibilities within the rich lore of Percy Jackson.
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.
Well, one possible plot could be that Percy, as the reincarnation of void, has strange new powers. Maybe he can manipulate emptiness or darkness in a way that both helps and scares his friends. For example, he could use it to create barriers of nothingness that enemies can't cross. But at the same time, he has to struggle with not being consumed by the void within him.
One possible plot could be that the Avengers mistake Percy for a threat. Maybe they see his powers with water and think he's some kind of new, unknown enemy. They capture him to figure out what he is. Percy, of course, would be confused and probably a bit angry at being wrongly accused.
The plot could involve Percy traveling to Japan to learn more about his newfound 'parentage'. There, he meets other Japanese demigods or spirits who either help or hinder him. Maybe he discovers a prophecy that only he, as the son of Amaterasu, can fulfill, which has something to do with saving both the Greek and Japanese mythological worlds from a great threat.
