Uchiha brothers vs kisame and nagato

[Misconception]

Sasuke solo's people say his Ps sword had no feats... It broke the Rikudo's dna sword... With those feats ill put it above Madara's...

 

[Transcendence]

I give it to Uchiha Sasuke and Uchiha Itachi. It takes a little amount of insight to tell that Sasuke's PS is on Madara's level. When he was shaping it to Naruto's Bijuu Sennin Modo, the entire head literally engulfed the avatar and had to shape to it. It was much larger by contrast. Under this assumption, Sasuke could probably solo this fight given the power of the shockwave from a PS sword. Not to mention the application of Enton on his sword. Kisame would quite easily be caught in the crossfire and he is pretty much Genjutsu/Ama bait and doesn't have the speed to dodge it. Nagato, while valiant, can't defend against such a shockwave and even if he absorbed the slash, it wouldn't trounce the overall momentum of the swing and would basically be assisted suicide in this case. Factoring in Itachi makes this a rather easy win, as he can quite handily dispatch of Kisame with Enton support from Sasuke.

Itachi solos with genjutsu. Sasuke solos with genjutsu. That simple.
