Like a typical Kineceleran, K8-E has blue skin, wheeled feet, a tail, and three-fingered hands.
K8-E wears a light blue stomach-bearing tube top, light-blue short shorts with a black-and-white belt, and a white collar-like garment around her neck. She has a gold ring piercing on her bellybutton. She also wears a black helmet, which is typical to her species, but the tip points downward, similar to a ponytail.
K8-E has black lips and white eyes.
