Tartaglia is tall and 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. A few lighter blond streaks can be seen in his hair, with one prominent one on the left side of his bangs. Wherever he goes, danger follows, and Childe is always eager for a challenge, making him extremely dangerous despite being the youngest member.
