Despite holding one of the most senior positions in the Fatui as one of the Eleven Harbingers, Childe very much looks like the young adult that he still is. He is a wolf in sheep's clothing, however, for under the cheerful and confident appearance lies a deadly swordsman. He has short ginger hair and dull blue eyes. He wears a red Fatui mask pulled off to the left side of his head, and a beaded earring with a red crystal on his left ear.
