Rob Lucci is a tall, slim yet muscular man with arched eyebrows and a close-shaved goatee. His shoulder-length wavy black hair is often tied in a ponytail, and his pet pigeon Hattori usually perches on his right shoulder. He bears a tattoo of a crossed-out square on each upper arm and five cannonball scars on his back in the shape of the World Government symbol. Despite his handsome features, Lucci exudes a cold, distant aura. As a CP9 agent, he is completely psychopathic and amoral, feeling no true bonds with anyone. He speaks little, often using Hattori to communicate. His calm demeanor hides a ruthless killer.
