Percy Jackson is the son of Poseidon, and it shows — there’s a quiet power in him, like the sea before a storm. His black hair is always a little messy, his sea-green eyes sharp and restless, carrying the kind of depth that makes you wonder what he’s seen. He moves with easy confidence, never showy but always sure of himself, and there’s a constant edge of humor in the way he speaks, even when things get dangerous. Brave to a fault, loyal beyond reason.
