Katara is the last waterbender in the entire South Pole. She is the second child and only daughter of Southern Water Tribe Chief, Hakoda, and his deceased wife, Kya. When she was twelve, her father left with the other warriors of the tribe to fight against the Fire Nation, leaving Katara and her older brother, Sokka, to lead the tribe. While on a fishing trip with Sokka, she discovered the long-lost Avatar, Aang, frozen in an iceberg. The two liberated him and afterward, accompanied him on his journey around the world to prepare for his battle with Fire Lord Ozai.
