Zuko's younger sister. Her current whereabouts are unknown.
Azula is Zuko’s younger sister. She has always been a bit smaller than other dragonborn. She is a blueish shade in color, but other than her strange scale color, she has features resembling Zuko’s mother. There would be little doubt of Zuko and Azula’s being siblings. As a child, she tended to carry a small doll with her wherever she went.
