Aerodactyl is a reptilian, bipedal Pokémon with large, membranous wings. It has sharply pointed ears and a fierce expression with intense eyes. Its snout is ridged, with a gaping mouth and strong lower jaw full of serrated fangs. Its body is covered in light violet-gray skin with violet wings. Aerodactyl's wings consist of a membrane running from the side of the body to the tip of an elongated finger. The clawed hands at the bend of each wing allow it to grasp objects. A hump-like ridge grows from its back and it has a strong, arrow-tipped tail.
