Ehh????
He's an uzumaki.What you said is pure speculation.
Quite easily????lol
You talk as if Itachi is a fodder lol.I'll say it again,nagato in a 1vs1 has no counter to totsuka blade.Itachi is like a 100 times faster than nagato.Who has a better chance of using their techs first???When Itachi used the totsuka blade on nagato,so called "best sensor";he couldn't even notice the attack until he was hit.
I admit itachi is inferior to pein but nagato can't win a 1vs1 against Itachi :yeah:
Its not speculation to use the gedo mazo you must have uchiha and senju dna seeing as he sealed the beasts for 150 chapters with it and used gedo mazo rinnei tensei the most advanced gedo mazo technique its safe to say he can use it.
When Nagato was sealed ihe was being controlled by kabuto who admitted it was his fault. Every attack on Nagato was a surprise attack and why ? because itachi knows something itachi fanboys don't ... he would get completely owned.
Nagato would solo itachi and sasuke at the same time you do realise how strong nagato is and that he can just fly in the air spamming attacks something itachi cannot counter .. ever. He also has gedo mazo(juubi) which would solo itachi do not say totsuka as the sage of 6 paths couldn't seal it was that strong.
The only way itachi could win legitimately against nagato is if he suffered a heart attack.
