Everyone has different reasons to fight for something. They fight for their family, their pride, their fame or their power. For the world. Some just fight, without a reason. Most for themselves.
Percy Jackson fights for humanity. He fights for the people, his friends, his family. He fights for the ones in need. Often people underestimate what he would do for the ones he cares about.
Percy Jackson does not fight for the gods. He fights for the world. Even if it means having the gods on his side. Even though every part of him wants them to leave him alone. To let him heal from the past.
Percy Jackson is a boy who fights for everyone who can't fight for themselves. Even the ones who can.
He fights for them. But for what? Another threat, another prophecy, another war. What's his prize?
All Percy Jackson wants is peace, and safety. But he keeps fighting. Because the world needs him.
They need him to fight for them.
