Since I can't vote (don't know how to vote on the poll) I would have to say the Third, he was the perfect image of underestimating your opponent when fighting Oro, i mean, when I saw him drop to the ground and kick out at Oro's feet after they had been talking about his age I think it was, it was just cool a classic show of underestimating your opponent. Oh and also he was really cool.

Kakashi and Rock Lee were tied at a close second. Kakashi is just cool (facing an opponent who was a ANBU team leader at 13 and not only that, has mastered Sharingen and is a Type-S ninja is no small feat ... also memorizing 1000 jutso's) and Rock Lee because of everything everybody has already stated, the guy works so hard you just can't help but respect him.
