Slither Wing is a large, moth-like Pokémon with four legs. It appears to have compound eyes that are two shades of red, and there is a red spiny horn-like structure on each side of its face. The fuzz on its body and legs is smoky white and messy. Its thorax is navy blue in the center, and its tail-like abdomen is teal with black dots. It has six leaf-like wings that are orange in color with yellow-orange tips and small green diamond-shaped marks, but they do not seem to be strong enough to allow it to fly. Even though it is mostly quadrupedal, it can stand on two legs, mostly during battles.
