What are Percy Jackson's character traits, specifically in chapters 1–6?

Percy Jackson is a twelve year old with a humble home life. His classmates at Yancy Academy talk about the exotic locations they plan on traveling to for summer break. In contrast, Percy will have to work over the summer, and he is not even certain where he will go to school come fall. Percy has a hard time in school because of his dyslexia and attention deficit disorder. He was kicked out of six different schools in the past six years, leading him to think that he was a magnet for trouble.
Percy narrates his own story, starting off with a comment that hints at the struggles he would rather have avoided: “Believe whatever lie your mom or dad told you about your birth and try to lead a normal life.” Everything changes when Percy Jackson discovers he is a half-blood. Whereas before he was a quiet kid just trying not to get kicked out of school, now he finds himself caught between feuding gods, fighting monsters, and learning to survive in a whole new world.
Percy is quick to jump into action. When bullies attack his friend Grover, Percy comes to his rescue. He demonstrates how capable he is when, with some coaching from his mom, he defeats the minotaur. Percy Jackson is a character defined by his bravery as well as his kindness.
