Katara (Avatar: The Last Airbender)

Katara is a fictional character in the Nickelodeon animated television series Avatar: The Last Airbender and its sequel series The Legend of Korra, and is part of the Avatar: The Last Airbender world. The character, created by Michael Dante DiMartino and Bryan Konietzko, is voiced by Mae Whitman in the original series and Eva Marie Saint in the sequel series, The Legend of Korra. She is Chief Hakoda and Kya's daughter and Sokka's younger sister. In the 2010 live action film adaptation, she was played by Nicola Peltz, while in the live-action television series adaptation, she is portrayed by Kiawentiio.

Katara is first introduced as a 14-year-old "waterbender", meaning that she has the ability to control water and ice. She later learns how to utilise waterbending to control water in the bodies of living things, a subskill known as "bloodbending". At the beginning of the story, she is the only person with such abilities in the Southern Water Tribe, one of two known communities in which waterbending is practiced. She and her older brother, Sokka, discover an "airbender" (one who can manipulate air) named Aang frozen in an iceberg. They free him and accompany him on his quest to defeat the imperialistic Fire Nation and bring peace to the war-torn world.

Katara's history is marked by loss and the temptation of vengeance; she once stood before the man who killed her mother, with the power to end his life, yet she chose mercy, a choice which speaks volumes to her strength of character. She is recognized as the greatest waterbender of her generation, earning the title of Master Waterbender from Master Pakku of the Northern Water Tribe. In her adulthood, Katara married Aang and they had three children: Tenzin, Kya, and Bumi. In The Legend of Korra, Katara is a high-ranking member of the White Lotus and one of the last surviving members of Team Avatar; being personally chosen by Korra as her waterbending teacher.

Katara has appeared in other media, such as trading cards, T-shirts, video games and web comics.
