Avatar: The Last Airbender story idea.
Let Me know if anyone would like to see a fully fleshed out story of this idea and i will get to work on it As soon as i can.
I started rewatching this series the other day and ever since Ive had this idea in my head on what if Aang wasnt the avatar. he still managed to be saved in the ice berg but by the previous avatar who died. and the new avatar turned out to be katara but no body realised it. so katara and sokka find Aang in the ice berg and Zuko shows up to take Aang but they find out the avatar is katara when she and sokka go to save Aang from zukos ship
