Agent is black anthropomorphic cat with yellow eyes. He wears a crisp white button-up shirt with long sleeves, the cuffs extending neatly over his wrists. Layered over it is a fitted black vest with a deep V-neck, tailored closely to his torso for a sleek silhouette. Around his collar is a solid black necktie, hanging straight down the front and adding to the refined appearance. His bottoms are high-waisted black trousers with a relaxed, slightly wide-leg fit.
