Black Sapphire Cookie is a tall, lanky individual with a confident, snide, and theatrical personality. He is full of himself and delights in his ability to twist words and spread rumors. His dough is a cool grayish-purple, and he has a sly expression with sharp teeth. His fluffy, short hair is a violet-rimmed obsidian that hides one eye completely; his visible eye is deep black with a lavender slit pupil. He dresses like a sophisticated entertainer in a tailored black suit with gold accents, a white cravat, and a white rose on his lapel. His jacket has leg-of-mutton sleeves and is accessorized with onyx jewelry. A set of devilish, bat-like purple wings are attached to his back, resembling a formal swallowtail coat.
