Percy Jackson

Percy has tanned, olive skin and disheveled black hair. He has sea-green eyes, which he inherited from Poseidon. Although he is not extremely fit at the start of the series, his training over the course of the books results in a muscular, lean frame.

They all live at Camp Half-Blood. Camp Half-Blood is a Greek demigod training facility located on the north shore of Long Island. The camp is directed by the god Dionysus, who the campers call "Mr. D," and Chiron, a Centaur who is the activities director. It is also the Greek counterpart of Camp Jupiter, a Roman camp between Oakland, California and Berkley, California.

Percy is a very kind-hearted, brave-spirited, natural leader. Many people tell him he is brave, such as friends, family, strangers, and even gods. He has the same "brooding" look as his father, which always had him branded as a rebel; his mother has a rebellious streak just like him. Percy is characterised by his sarcastic, smart sense of humor, and laid-back demeanour.

Percy is somewhat short-tempered and thus has trouble controlling his anger, such as when he sees bullying. He can be derisively sarcastic and moody, especially when someone tries to manipulate him or forces him to obey. He does not like to follow rules, as shown when he escapes camp to go on the quest to save Grover, and when he bowed to Poseidon before Zeus. Like many heroes, Percy is very reckless and tends to do or blurt out things before thinking, causing him to get into a lot of trouble. He feels responsible for everyone and anything which goes wrong.

Percy is obtuse, meaning he doesn't always see the obvious even when it is right in front of him, such as people's feelings and what they are trying to say indirectly. Although he has many friends in Camp Half-Blood, Percy is considered a troublemaker in school with a track record of expulsions, like most demigods.

His dyslexia makes learning and reading difficult and his ADHD makes it hard for him to be attentive or to sit still in class. He has never been one of the "cool" kids in class because he hangs out with supposedly "un-cool" people, such as his best friend Grover Underwood or his half-brother Tyson. Possibly because of his bad history in school, Percy feels a strong level of affection and attachment to Camp Half-Blood.
