Espresso Cookie is a Cookie of average height and thin build with thickish legs. His color palette overall is very dark, moody, and brown, with even the lightest values present being warm mid-tones, and his shape language largely consists of sharp triangles with some circular complements. At his base, his dough is a rich, dark sienna color while his smug eye is outlined with thick, long lashes in a Van Dyke brown. Espresso Cookie's iris takes a dull dusty rose color and lies beneath a sharp pupil, that being indicative of his Coffee Tribe origins and rendering his inner eye to overall resemble a coffee bean. Only the mage's left eye is ever visible with the other being hidden under hair. His thin eyebrows are lifted in amusement and his black smile is slight and confident. Additionally, he wears oversized glasses of metallic white gold whose lenses each resemble a coffee cup as seen from above. Espresso Cookie's hair is straight and colored in violet-toned ebony at its base. Its style is quite complex: most notably, a single large, curled bang swoops across the right of his face, completely enveloping his eye and coming to nearly his chin. It ends in a point away from his face and is peppered with mostly subtle highlights: from the outside to the inside, two are thick and warm tungsten, one is thin and black, and the final lines the inner edge of the hair in a creamy beige and ends in a prominent swirl at the top of his head. The rest of his hair is tightly combed back into curled tufts which radiate from the sides of his head. The back of his hair sports a large swirl similar to that on his bangs which radiates out from his scalp. Though much of its length is lofted into the hair, Espresso Cookie's hair is long enough to be styled into a ponytail. The researcher's clothing fittingly sources dark academia fashion with hints of gothic or fantasy styling. Espresso Cookie 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. His facial expression generally defaults to a composed and confident smile, but there are instances where he doesn't bother hiding his displeasure or exhaustion (such as when faced with a preventable failure or Head Icon Madeleine Cookie's running mouth). Despite this, he is capable of being polite in his conversations with other Cookies, and takes interest in their actions, like when he asked to read a report on Head Icon Alchemist Cookie's reagents. Espresso Cookie is a Professor at the most prestigious university nearby. He’s also a cunt boy and a Maschostic Tsndere
