Avatar: The Last Airbender. The Teen Years.

Ok so any fan of the show Avatar knows that he is the last Airbender. Like ever. They were all killed by an imperialistic Fire Lord named Ozai. Well that's a heavy thing to deal with. Right? Being the sole survivor of an entire race. That's a lot for a 12 year old to handle. So it's my speculation that when Aang reaches 15-17 years of age he falls in with the emo crowd. I believe this is even what he may of looked like during that phase in his life.
