Katara is a waterbending master, born and raised in the Southern Water Tribe by her grandmother, Kanna, alongside her older brother Sokka, and is the daughter of Chief Hakoda and Kya. During her childhood, Katara was the last native of the South Pole still living there who was capable of waterbending. At first she lived a peaceful life with her family, until she lost her mother in a Fire Nation raid. Years after this tragedy, as a teenager, she and her brother discovered the young Air Nomad Avatar, Aang, who had been frozen in an iceberg with his bison, Appa, for one hundred years. In need of a waterbending master, the siblings and Aang left the South Pole, headed to Northern Water Tribe. Katara and Sokka eventually became close friends of Aang, and after their journey to the North Pole, continued to travel with him across the world as he mastered the remaining elements, earth and fire. The siblings' assistance helped Aang halt the Fire Nation's ambitions of world domination, ending the century-long war, and finally restoring balance to the world.
