These winged lizards possessed heavily muscled bodies covered by purple scales. Their long necks held small heads with short, wide snouts and sharp fangs. An adult drexl's largest teeth were the length of a Human arm, and the creatures had a stature similar to that of a krayt dragon when fully grown. A fully grown male specimen had a wingspan of twenty meters across. The peculiar orbit of Dxun around Onderon allowed them to migrate to that world.
