Uhhh hmm when was this made..... I believe right before that Naruto/Sasuke picture... and i mean RIGHT before..... ahem about 2 hours work, and yes I know its not that great...... but hey you try drawing that friggen face!
This is Captain Yamato(NOT HIS REAL NAME) he is filling in for Captain Kakashi while hes unable to preform his Captain duties. Yamato is really a Anbu, he was assigned to basically control Naruto incase he goes beserk and starts to turn into the Kyuubi(at this point in the series Naruto has made it to four tails and nearly killed Jaraiya-sama, and Yamato is assigned to him only because he has the "wood" techniques that the First Hokage[ummm may be wrong here it might be 2nd, its been a while] -_-'' had which gives him the ability to control the Kyuubi)
Yamato is a hard guy to figure out at first but as the series progresses he opens up more and becomes a reliable character, who will protect his friends and finish his assignment with little to no flaws.
