Bryan Konietzko: “As one of the primary gatekeepers of what is canon in the Avatarverse, I have to make it clear that Ming-Hua was born without arms, due to a congenital disorder. This is a cool alternate interpretation by Eugene, though!” 

Joaquim Dos Santos: “If the story did not make you somewhat sympathetic to Zaheer and his gang, then maybe this image, which captures them in an earlier time, before life’s trials and tribulations have hardened them, will.”
