The Random World of Kiddy

Officially titled The Last Airbender: Legend of Korra the new series is set 70 years after events that occurred with Aang and crew in Avatar The Last Airbender. Korra who is referred to as a “rebellious” young 17 year old is the current Avatar who at the start of the series has already mastered Waterbending, Firebending, and Earthbending. She is apparently going to learn Airbending from Tenzin who is Aang and Katara’s Son and the father of a young family.
The conflict in the series surrounds the mysterious Equalist Leader known as Amon who leads an “Anti-Bending” Movement, the events seem to permeate around a relatively modern city known as Republic City.
