Sergeant Ethan Walker is a tall, broad-shouldered soldier with a strong, athletic build shaped by years of military training. He has short dark brown hair, sharp grey eyes, and a faint scar running through his right eyebrow from a past training accident. His posture is straight and confident, and his movements are controlled and precise. Ethan usually wears a serious expression, which, combined with his height and uniform, makes him appear naturally intimidating. Even when he isn’t speaking, his presence tends to command attention.
