"It was an accident." That was what Zuko had said to his crew when he used an element he hadn't been meant to. He wasn't the Avatar. The Avatar was supposed to be in the Earth Kingdom, hidden by its walls. Unless the old Avatar had died long ago ... and had already been replaced fifteen years ago. AU.

One year after defeating Darkseid, The League has expanded to include a third team. Where the black ops team operate on the sly, this new team will be publicly known. But now a new threat is on the horizon, one with a strong foot hold in Earth and looking for the perfect chance to strike with neither Earth's heroes or villain's knowing anything about it. My version of a season 4.
