Espio is a purple anthropomorphic chameleon with a yellow horn between his gold eyes. His muzzle and the heart-shaped pattern on his torso are peach in color. He has a ridge of three black spikes going down his spine and a coiled tail. For attire, he wears dark purple shoes with black accents, metal-reinforced arm bracers, and white gloves with dark purple pads on the backs. Around his wrists and ankles are bandage-wrapped cuffs with gold studs on the lower bands.
