if I'm not mistaken kakashi don't use his ninjutsu before that right?
I remember when he used his ninjutsu on zabuza kakashi got the upper-hand. He could kill zabuza but haku intercept it with his body to protect zabuza. The thing is in part1 they used taijutsu a lot.
In manga part2 kakashi...
No it can't. 10tail is Too powerful.
U can't say one of the seven sword man (the guy who own a blade could crush any defance) could destroy madara's PS because "PS is a defance".. Sometime charecter can over hype other charecter.
He's physically stronger the any kages.. But to me the 5 kage are comparable in power.. (Not juat in strength but overall power)
They are special in there own way..
