my vote goes to sarutobi
Kick me high, hit me low, spit on me it's gonna take more than that to break my soul.
Ay ByaKuya_ I can't believe you never read that
As far as potential goes: Minato and Orochimaru.
Why anybody is voting for Orochimaru sama? We could see him acting in his prime (more or less) when he fought the 3rd. He was very healthy and could survive to Shiki Fuujin and succeed killing the old geezer.
And most of the time, he fought formidable but not at his full throttle. Like when Tsunade pwnd him in front of Manda, Gamabunta and Katsuyu. Or when Sasuke kun attacked him in his bed.
´K, then he was at his prime.. ur right...
OH I love your avatar dude. XD
I think oro was at his prime when he fought Naruto in 4 tails, when they fought Hanzo they were not as skilled as they were after the 3 year time skip.
