Yes! This is DEFINITELY Sokka
Welllllllllllllllllllllllll, this is my design sheet for Sokka in my up-coming doujinshi "ALAB: Way of the Warrior", which basically focuses on Sokka, Prince Zuko, Haru, and Jet.
In Way of the Warrior, which originally was a fanfic I'm STILL working on--not on ff.net yet--Sokka gets separated from Katara and Aang by a Firebender raid at the village they were resting at. He runs into trouble, gets "rescued" (Sokka won't admit it, he says "helped out by"

) a group of NON-bending warriors who are rebelling against the fire nation. The leader, Hisaku, is hesitant at taking Sokka in the group at first, but with persuasion from one of his best warrior's, "Swat" (his real name's not known), Sokka is on his way to becoming a warrior!
As for why his hair's changed--well--it's an important part ;D
...That's all the plot I'm revealing now--don't want to spoil it

*well...plus typing is tiring*
