Lol what? Let me remind you that itachi got help from Naruto and freaking bee xD, let me also remind you just because you were brought back as an Edo doesn't mean you'll be at full power as if you were alive. Alive Negato>>>>>>>>Edo Negato in terms of raw strength. Heck a path of pain that was only an extension of negato's power blew up all of Konaha and that wasn't even the original body. Imagine alive negato, dude would've blown up a LOT more than konoha. It'd be like comparing an atomic bomb to a tsar bomb. Alive negato megs Itachi sorry Itachi fans but as swagbito says "deal with it". But itachi vs all six paths? Itacho still gets low diff'd if not negged, what ameterasu? Negaato would deva him before he can even flinch. What tsykyomi? The bodies are already dead, lel. What susano? That's literally itachi's best bet but pain can out last that, itachi would have to keep final susano up, and pain would eventually find a way to beat it anyways. Without susano, deva path, human path, gg. Itachi isn't doing much against re paths to be honest.
