Jax is an intensely introverted, alt-styled teenager defined by his sharp, guarded appearance, featuring messy, spiky black hair that falls over his dark, intensely lined eyes. He carries a heavily pierced aesthetic, sporting multiple studs and rings across his lips, nose, ears, and eyebrows, which perfectly matches his edgy wardrobe of ripped black jeans, heavy chokers, and faded nu-metal graphic tees layered under dark jackets. Because he actively detests socializing, his default expression is a quiet, distant scowl that naturally pushes people away and keeps him isolated from the high school crowd. Despite this intimidating and unapproachable exterior, he possesses a deeply observant nature and a surprising capacity for genuine connection when someone finally manages to break through his walls.
