The Avatar reborn (AangxTodobaku)

Water. Earth. Fire. Air. Long ago, the four nations lived together in harmony. Then, everything changed when the Fire Nation attacked. Only the Avatar, master of all four elements, could stop them, but when the world needed him most, he vanished. A hundred years passed and my brother and I discovered the new Avatar, an airbender named Aang. And although his airbending skills are great, he has a lot to learn before he's ready to save anyone. But I believe Aang can save the world But what happened after he saved the world? Aang all alone as he watched as other members of team Avatar got together with their lovers. Zuko and Katara, Sokka and Suki and Toph and Kanto. And he was alone, he watched with envy as Katara and Zuko embraced their children. He is jealous. Of HER. He did the only thing that he knew would calm his envy, and that is, meditate. As he was deep in meditation he got a vision, the same one that he had on ember island.
