An attack that can penetrate this much density in a instant is clearly powerful its a air "cannon" what form of rasengan can cut threw a cannon strike and naruto dosent know how to use TSB
sasukes susanoo is not more durable then the earth itself i understand that he can slice mountains and level a battle field with ease
but, not punch or take a clean shot like bullet to the earths "core" (the initial full attack purpose) and survive.
The attack will go clean threw the skull of susanno and buy his pseudo flight speed running typhoons his big ass susanoo will get dizzy lol or be to big to catch
also people say sasuke cut madara in half while gai used his best to do so but difference is madara was bloodless and unconcerned....? night gai wasn't aiming for the tree but madara who was feet away. and when the attack concluded gai leg broke before tree
impact, as u can see gai is far from the tree, witch is why madara past his death up (also PnJ no head shot) naruto hit madara while he was still sitting on it and no doubt rasenshurkin can do that easily same with sasukes sword
this is to all my gai haters who think these two hero fodder compare to the beast...the man left you gai a half dead man and they let him blues them to get kakashis eyes who gai had no prob protecting
well naruto faild it mostly talking and saving and shit thats why im a sasuke fan though cool with naruto
