Katara - Yenra Picture Wiki
Katara is a fictional character in Nickelodeon's animated television series Avatar: The Last Airbender and The Legend of Korra. 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.
Katara is a fourteen-year-old waterbender (i.e., she has the ability to telekinetically control water and ice); at the beginning of the story she is the only waterbender in the Southern Water Tribe, one of two known communities (along with the Northern Water Tribe at the opposite pole) in which waterbending is practiced.
She and her older brother, Sokka, discover an Airbender named Aang, the long-lost Avatar, frozen in an iceberg, and accompany him on his quest to defeat the imperialistic Fire Nation and bring peace to the war-torn world. She later earns the title of Master Waterbender from Master Pakku of the Northern Water Tribe at the age of fourteen.
