Itachi alone is all that is needed
Itachi would commit suicide.
OT:We don't know how strong was Hagoromo at his prime , he would solo Narutoverse if he really was able to create everything that exists in that universe with his Nunoboko sword.
Yes, i think his powers are pretty unlimited, he created the entire ninja world basically. With COAT the sky's the limit.
-He is
said to have created the world with this Nunoboko sword , that's not a manga fact.
We never saw him use that sword , so it's not a fact that he had that sword , it's a legend.
Obito claimed that Hagoromo created the world with this sword , but he didn't give us his source.
It's possible but it's not a fact.
-For the COAT thing , it's a mangafact that Hagoromo used that jutsu to create the 9 beasts (like a little planet) , but it's a legend that he used that jutsu to create everything in the universe (a big planet , the sun , the stars , life...) , and there is a huge difference between the 2 things.
-Maybe some"body" else did those 2 things , but probably not Hagoromo , because the world existed before Hagoromo's birth.
Uh...how about no? Lol. Naruto and Sasuke are each half of Hagoromo's power. Madara is on par with him or Hamura individually. Naruto and Sasuke with their added power (Bijuu and Nature Energy) are on par with Madara who is on par with Hagoromo who is in turn on par with Hamura. Madara, Naruto and Sasuke are enough to take this match. Adding in Kakashi, Gai and Obito only makes it worse for them, especially since Kakashi's planning and his abilities were key in defeating someone much stronger than Hagoromo.
But of course that's all without the Juubi in play. Lol. Forgot to give it to him for this thread. If Hagoromo gets the Juubi, then it's not a stomp, but NV still wins, but everybody will be needed.
What?
You don't know a thing over Hamura , you don't know how strong was Hagoromo , your logic of Naruto+Sasuke=Hagoromo is not good...
