Kanna, also known as Gran Gran, is Katara and Sokka's caring grandmother on their father's side. Kanna is the oldest person in the Southern Water Tribe, but is not a Waterbender. Although she had her doubts about Aang at first, when it was revealed that he was indeed the Avatar, she had regained hope; something she probably hasn't had for a long time. She cares deeply for her two grandchildren.
