you sir are the smartest person on NB, Ive said this so many times that like beating someon up and ppl still say he can beat you. He saved bee and naruto, he also sealed him. why stop cs when you can just seal nagato while its being created? nagato is too slow, itachi can spam amateretsu, plus he's so much more intelligent. there is a reason tobu was the real boss and ordered pain around. theres a reason tobi didn't start this shit until itachi was gone. theres a reason itachi call tobi a pathetic shell.
Itachi>TOBI>nagato
only person above itachi is madara because he only has to worry about the weapons and itachi's intelligence as opposed to the weapons and all the uchiha jutsu's.
One question how can nagato stop izami
