Blaze is a lavender-furred, anthropomorphic cat with golden eyes, a small black nose, and a white-furred muzzle. She has triangular ears with peach-colored canals on top of her head, two medium-length eyelashes on each side of her eyes, and a long tail with the end frayed and violet. Her fur is longer on each side of her head and sweeps slightly upwards. She has four plumes of hair with violet tips done up in a high ponytail with a red hair tie. She also has a red oval gem on her forehead.

For attire, Blaze wears a golden collar hanging from her neck, a violet tailcoat with rose trim at the bottom, and simple white leggings. She also wore white gloves and high-heeled rose ankle boots, both featuring white fluffy cuffs on them. Her boots also features a thick white stripe on each of the front, followed by both gray soles and gray heels.
