Altered | A Genderswap ATLA AU

Just what it sounds like. An AU in which the Gaang's gender has been reversed. When Katasi and his older sister Sokka discover a girl frozen within an iceberg, they find Aang, the long lost Avatar and very last remaining one of her race, the Air Nomads. A hundred years have passed since she'd disappeared, resulting in the Fire Nation attacking and spreading their war throughout the world as they conquered nation after nation, now under the rule of Fire Lord Ozai. Now it's up to the Water Tribe siblings to make sure Aang learns all four elements so she can defeat him and bring back the peace and balance.

So Katasi, the last waterbender in the South Pole, Sokka, and Aang set off on their journey to help her master the elements, but one constant problem cuts into their path at every opportunity. Banished Crown Princess Zuleika of the Fire Nation is hellbent on regaining her honor by capturing the Avatar herself and returning home, and nothing would stop her...

Sticks to the storyline of ATLA with a few changes.
