They have the same black lustery color of the normal shadow teddies, but they are a good deal taller, slightly above a human's typical height. Imagine a Yuanti Pureblood but tack on lizard features instead of snake and you have a decent picture. The horns typical of shadow teddies are gone, replaced with a very very short spines on the back of the evolved teddy's head and neck. They are draped in a faint orange robe that has holes slit in the back to accomadate their large wings. They have lizard like tails, complete with the ability to detach if necessary. Their eyes lack a pupil or an iris, instead just one solid 'white' that happens to be orange. They are covered with fine scales and keep the fangs and claws of the normal shadow teddy.
Not too friendly looking. Or teddy-like for that matter.
