Tock was a Crocodile Faunus with a shaved head, greyish-green skin, a messy dark greyish-green mohawk and yellow eyes. An x-shaped scar on the left side of her head, black polish on her nails and sharp metal teeth with two screws in them.

She wore a dark green collared shirt with a dark brown corset that has a strap attached to a narrow belt around her thigh, black and gray striped trousers and black shoes. In addition, she wore dark brown fingerless gloves and carried a large stopwatch.
