you mean that nagato who faced hanzou the salamander, then seeks help from gedo mazo?
Well I always thought it was negato after absorbed bee with full use of his legs but reading a couple pages back and see you guys are saying we can't use that to debate and I understand because it can be seen as a what if situation ok
But even still using the 6 paths it's too much for some of the people on that list
Tobi- agreed he can beat him
Kabuto- iffy but I could see him winning just because of ET.
Naruto- as much as I hate this goody goody he has a good chance of winning right now with his broken BM. (even thought sometimes I like I think negato is smart enought to find a way to win but that's just me)
Sasuke- I don't think he would win sasuke has no knowledge of the Rin at all he wouldn't know how to deal with them especially deva preta animal and human.
Bee- bee is strong I like him not many people can got toe to toe with him especially since he has samehada now but He can still drain him of his chakra and he still has to deal with deva along with the other 5.
Madara- agreed he would win.
Hashi- don't know enough but I'll give it to him because of the hype.
A-no knowledge of Rin he has absolutely no long range attacks yes he's fast as shit but i don't see him being able to beat deva.
Itachi- while he is one of the smartest people in the series I don't seem him walking away from this one especially since he only has ms yes is susanoo is godlike but he can't use it forever, I guess he could tsukoyomi.
Minato- I don't see this happening either but we don't really have enough info on him to tell but he has never faced a Rin user he doesn't know what it's capable of.
Deva is the real threat because of how fast he is (I know alot of people didn't like the animation used for that fight but it was ment to show how fast and powerful the two of them were.) and his tensi abilities. The other problem is actually knowing what the abilities are and how to counter them. Naruto had help from tsunades slug telling that pains powers.
