Korra

Korra was the Southern Water Tribe-born Avatar successor of Avatar Aang and predecessor of Avatar Genji.

Early Life
Korra was born to Tonraq and Senna in the Southern Water Tribe following the death of Avatar Aang in 153 AG. At the age of four, she proudly introduced herself to the Order of the White Lotus as the new Avatar by performing water-, earth-, and firebending before them. She honed her waterbending under the tutelage of Katara, though her instinctive aggressive style was nothing like the calm, slow movements the elderly master tried to pass on.

After Chief Unalaq learned that his niece was the Avatar, he constantly sought Tonraq's permission to train Korra in the spiritual ways of the Water Tribe, but his estranged brother shot him down. Since he secretly desired to indoctrinate Korra in the ways of the Red Lotus and coerce her to reopen the long-dormant spirit portals to release Vaatu, Unalaq commissioned Zaheer, Ghazan, Ming-Hua, and P'Li to kidnap her in 158 AG. However, due to the efforts of Tonraq, Chief Sokka, Fire Lord Zuko, and Councilman Tenzin, the attempt was thwarted, and the criminals were apprehended, although Unalaq's involvement remained unknown. After the incident, Tonraq and Tenzin decided to seclude the Avatar in the Southern Water Tribe compound, away from the public eye as she pursued the bending arts.

Later life
In 174 AG Wu and Korra managed to transform the Earth Kingdom into the Earth Federation and Wu abdicated. Four years later, Korra married Asami and two years later created the Global Assembly. In 189 AG a new president was elected, Jianwu; unfortunately the Earth Federation at that time was in danger of a serious economic depression and Jianwu to avoid the problem decided to invade the Si Wong desert and the misty swamp; in order to exploit the oil and mineral deposits present in the first, and the timber present in the second. The peoples who lived in both places opposed, but could do nothing against the armies of the Federation; Korra, unable to help both at the same time, decided to go to the rescue of the swamp tribe, also due to the presence of the Banyan-Grove Tree. Korra's intervention saved the swamps, but the Sandbenders were driven out of their homeland.

Death
Despite his victory, Jianwu was not re-elected and leader Dai Li, a man named Bao Jun, came to power in his place. A few months later Korra was killed in a terrible explosion. Following the avatar cycle, Korra reincarnated as a Sandbender named Genji.

Trivia

 * Korra shares similarities with Kuruk another avatar of the water tribe: both died young (Kuruk at thirty-three and Korra at thirty-nine), and the identification of both of their successors was erroneous.
 * Korra is the third female avatar whose predecessor and successor are both male. The first is Yangchen, and the second is Kyoshi.
