Trivia

 * She is the second named child of a member of Team Avatar, the first being Tenzin.
 * She was first announced on July 23, 2011 at San Diego Comic Con.
 * Chief Bei Fong's appearance bears a greater resemblance to her grandmother Poppy Bei Fong than to her mother, at least as seen in the Avatar:The Last Airbender series. However, this may simply be because her mother was never seen near the Chief's present age; Toph may have grown to look more like her parents during the time intervening between the two series before she died.
