Wrybacks are small humanoids with rubbery bodies and limbs. They have dark grey skins with squat heads, bulging cat-like eyes, vertical nostril slits, and wide mouths filled with curved, needle-like teeth. Their eyes dimly glow an oily blue or sickly green color. Their ape-like limbs are twisted, and each hand has three fingers with sharp ivory claws. Their feet have four prehensile toes, and are softly padded. They can move by walking, running on all fours, or brachiating.
