She's the Avatar. You gotta deal with it!!
17 year old Korra has mastered 3 of the 4 elements: Water, Earth, Fire, and Air. When it was decided that Korra had mastered Fire-Bending, Aang's son Tenzin was called to teach her the last element, Air.
Hope you like my cosplay!! I tried my hardest not to use the same items as previous Korra entries. :D The eyes and hair are the best, so NO complaining please.
