Avatar, The last Airbender

As some people know already, 2 nights ago was the final episode of
Avatar, the last airbender. They celebrated by making it a 2-hour
movie named "Sozin's Comet" instead of probably an hour show. Here
are some pictures from the past years of all the characters! (Except
all the Zuko pictures are from the 2-3 season, I couldn't find any
from the first.) Enjoy!
