Im going with Akatsuki. As long as they are working together.
Team 7 also have incredible team work even after 3 years of not fighting along side each other.
Itachi can protect them all from elemental attacks
So you're making Itachi the person who stand their doing nothing? Itachi can do much more but the fact that Itachi will be staying stationary will easily hinder his performance.One of Naruto's many KCM clones can emerge through the ground like he did to Neji in part 1 and attack Itachi from the inside of his Susanoo.
kill Sakura with Tsukyomi
Thus giving Sasuke enough time to take out Itachi with amaterasu.Losing Itachi is more harmful than losing Sakura.
and perhaps even suppress Narutos tailed beast chakra.
Please this is laughable at best.
Kisame will be the biggest threat due chakra absorbing giant water shark missle and samehada.
Samehada can't absorb anything enton/amaterasu related.Samehada couldn't absorb a normal Katon without whimpering.I can show you scans of amaterasu being hotter than any normal flame but i guess that's common knowledge for a Naruto reader.Also Sage Mode Naruto clone mixed with Kyuubi Chakra from the original Naruto can take on Kisame.
he cannot take in Sm too much since his sword will turn to stone.Amaterasu kills Kisame anyway but i felt like throwing in other scenarios into the equation.
Sasori will cover the battlefield in poison smoke and use iron sand as a another defense for the team.
Iron sand gets destroyed by any of Team 7's moves.I've already countered the poison.
Derp.
Diedara would have to stay as far as he can and just spam ranged explosives and land mines.
KCm clone shunshin no jutsu will one hit K.O him.Sasuke can knock him out with one move as well.KCm mode cloak tanks those weak explosions like C1 or C2.
Kakuzu can use Earth grudge for a devastating attack and keep his masks out to increase his survivability.
Explosion from FRS kills him.
I think i should make coffee in a few minutes.
And one key thing you guys are forgetting is that they will have to defend attacks simultaneously from 6 different akatsuki members. Like what if they all focus Sasuke first with those strongest attacks?
Also forgetting that naruto can make over 11 clones all in KCM,BM or SM.Team 7 outnumbers them.
