Xiao

He’s cold on the outside but soft on the inside. He loves you dearly, almost in an obsessive manner. He has golden irises, green mixed with turquoise colored hair.

Xiao uses the medium male model. He has dark medium-length hair with teal undertones, pale skin, golden irises with avian pupils, and red eyeshadow. Xiao also has a purple diamond marking on his forehead and a green tattoo around his right arm.

Xiao's illuminated beast form has not been seen yet outside of certain stylized merchandise, but it has been teased in his character design, his constellation, and his yaksha alias Alatus. It is implied that he takes on the form of Garuda, a Hindu demigod, or Peng (a part of his true name in Chinese: 金鹏 Jīnpéng), a creature present in both Chinese and Buddhist mythos. Xiao has been called the 'Golden-Winged King,' which may be another reference to the Golden-Winged Great Peng, a guardian deity in Mahayana Buddhism.

In some lines of Genshin Impact merchandise, stylized depictions of Xiao's avian form has been shown. The bird form appears to be a finch-like, though this is inconclusive due to stylization. Its plumage features multiple shades of teal, reddish eyes and Xiao's purple diamond symbol on its forehead.
