Mobile Nagato solos assuming he knows how to release Edo Tensei.
Itachi's feats against him were only achieved because it was a 3v1 and he had been told, by Naruto, how to fight him.
You guys are mad underestimating Nagato. Dude's probably the strongest guy to ever live outside of Madara/Hashirama/Sasuke/Naruto and any Ootsutsuki.
He's got immunity to all visual genjutsu. He is a taijutsu master. He can absorb ALL forms of Chakra. His summonings (which he can do en masse) are almost as strong as the weaker Bijuu. Then there's the Gedo Mado, which solos anyway. This isn't even getting into Shinra Tensei, Bansho Tenin etc. let alone the fact Nagato is acclaimed to be a master of all 7 chakra natures and can literally marionette opponents with his chakra's pressure alone if somebody gets too close to him. The dude is a MONSTER and neither Minato/Itachi have anything that can top that. I mean, I haven't even mentioned soul extraction yet, that's just overkill, and it would probably end the Edo Tensei jutsu too now that I think about it.
Like, dont get me wrong, Itachi and Minato are monsters in their own right, but they simply cannot handle the Rinnegan. Nagato is the most underrated character man.
