I think that's the school teacher - Naruto's first sensai. I can't remember his name though. He shows up a lot in the first few episodes of the anime, and then some more around the time of the advancement exams/leaf village invasion. At this point on Cartoon Network (don't judge me, dial-up and a light wallet limits my options) he's leading all the wee lil ninja through an evacuation "drill." Hmmm... I should learn to summarize better or something...
I don't know if the lack of scar is that strong of an indicator. You could be correct, but the piece as a whole isn't very detailed or true to the original style. Look at Sakura for instance.
comment #42031 Hmm. Hadn't thought of that. Doesn't he have long black hair, or have I been reading the manga for too long and not watching the show. hehe.
