- ...a passionate, rebellious, and fearless teenaged girl from the Southern Water Tribe...

Korra is a character in Avatar: Legend of Korra. Not much is known about her.

Rumors (Partially Confirmed)
MTV, with information from a Nickelodeon press release, confirming some of these rumors.
 * Korra is a girl.
 * She is the current Avatar, after Aang.
 * She will be a waterbender, from the Southern Water Tribe.
 * Aang will mentor her from the spirit world, as Roku mentored Aang.
 * She has mastered the elements Water, Earth, and Fire.
 * Aang and Katara's son, Tenzin will be Korra's airbending teacher.
 * The series is set 70 years after the original series.
 * There will be flashbacks of the original characters.
 * More steampunk influenced.
 * There is a revolution and prejudice between benders and nonbenders.

Speculation

 * As she is Southern Water Tribe, she could be the granddaughter of Sokka and Suki.
 * She also could go into avatar state and might have Aang's personality. Though, this is unlikely, considering that when Aang entered the Avatar state, he was controlled by the power of all the Avatars that came before him. The same will probably happen with Korra.
 * Korra is probably between 16 and 18 years old judging from the picture. This would mean Aang died in 152/154 ASC and only lived 164/166 years. If the method of letting the avatar know their status, which would mean that she would of been told when she was sixteen, and due to the fact that mastering the elements takes time (Aang was under special circumstances, and Korra has already mastered 3 of them) would mean that Korra would more than likely be about 20-22 years old. But of course this is not true as the press release said she would be a teenager, aka between 13 and 19 years old.
