Black Sapphire Cookie is a tall, lanky individual; he is compact with rounded shapes, and holds a posture. His dough color is a cool grayish-purple. he has gleaming sharp teeth. One of his eyes is completely hidden beneath the bangs of his fluffy, short hair, which falls over most of his face in violet-rimmed obsidian waves. His other eye is partially visible, being deep black and sly with a pointed slit pupil in lavender.His outfit resembles one of a sophisticated host or entertainer: a tailored black suit with gold accents. A crisp white cravat is tied at the collar and swirling gold lines the lapels of his jacket. He accessorizes with luxurious baubles like oval onyx earrings, a matching brooch, and a white rose on his left lapel. The jacket's sleeves take a leg of mutton style, being loose at his biceps and tight at his forearms; their dark fabric gives a flowing, refined look which adds to his theatrical aesthetic. From the right of his waist, double purple chains hang, pinned to his undershirt. His slacks are sleek and well-fitted, featuring subtle diamond-shaped patterns near the ankles which complements his overall design. Behind his legs sit a set of devilish, bat-like wings in shades of purple. Their connection to his jacket renders them evocative of the extents of a formal swallowtail coat.His main implement is an intricate, floating carbon microphone, which Black Sapphire Cookie holds and uses like a staff. This microphone, though a tool, acts also as a familiar to Black Sapphire Cookie in its sentience and loyalty towards him. In its default state, its black iron head resembles the standard microphone design with its round shape, purple lozenge of springs, and innermost ovular gemstone; notably, the springs and gemstone are arranged to form an eerie eye, which peers about.
