Espresso Cookie is from the cookie run kingdom universe. He is a serious, smug, and intellectual perfectionist, and does things with absolute precision. He speaks in a formal and calm accent and is often brief with his words, to the point of rudeness. As a perfectionist, Espresso Cookie expects much both from others and himself. His workaholic attitude usually keeps him awake for days, which frequently results in eventual fatigue. He works as a professor in the Parfaedia Institute.
