I have more I'm going to do, but this'll do for now. Bunches of stuff. Sorry about the quality for some of the Sokka ones (the first half or so), the caps I got...weren't good. But the rest are better, I promise!
Credit, comment, no hotlink, feel free to alter (or ask for alterations). Also, please credit the makers of the fanart for those icons made from their art.
