Naruto vs Sasuke
2 TBBs finish the job no matter how you look at it. Sasuke needs some tanking feats.
Kamui
Kakashi's kamui one shots all currently, with Obito being an exception.
Perfect Susano'o
PS Slash could have solo'd the entire alliance by now, bar Naruto and edos. Dat plot.
Danzo Is Underrated
10 (11?) minutes of free respawns and redos. Plot (Le Sauce) killed off this OP character.
Flower Tree World
The pollen of Flower Tree World one shots most shinobi. gg.
Any others I should add?
If sasuke get perfect susannoo which he already has in a way, he can tank the tailed beast balls.
Kamui is super powerful but has only been shown taking down extremely linear targets.(while naruto has amazing speed kakashi let him in on the plans that resulted in him being kamui'd.
He has been fighting hashi for the longest, no time to slash the alliance, before that hte were testing juubi's power, some plot but nothing that can't be explained
He can can come back a limited amount of time and whats more Is the simple fact that while incredibly powerful outside of his sharingan abilities that he stole he does not match up to the other kage we have been shown.
Onoki seemed to have overcome it ith pure will power alone. Perhaps it can defeat most ninja but it is hashi teach so what do you expect. Ama can kill most ninja too, excluding naruto, MS users, Sages and a select few kage. Powerful techniques are supposed to be like this
