Those who could defeat him:
Tobi- master of most dojutsu
Naruto- mastered the nine tails
Hashrima- woopes his but before
Itachi- his sacred weapons tie the tie ( he is better than Nagato, i think it is so funny when people try and argue with this even when Itachi defeated him in one blow)
Naruto hasn't mastered Kurama yet, he can only be in Kurama's form for 5 mins while Bee can last for as long as he wants.
Hashirama def. Madara with EMS. this Madara that Hashirama would go against has rinnegan, can use EMS, susanoo, he can even use Mokuton and more.
Itachi didnt def. Nagato alone. He had Naruto and Bee's help. W/o them Itachi would have died a second time. Chibaku Tensei was destroyed from Itachi's Susanoo, Naruto's Rasenshuriken, and Bee's tails beast bomb. Itachi's Susanoo can't def. Chibaku Tensei solo.
Back to the Thread, I believe in my opinion (don't quote me on it, it's just an opinon as for everyone's elses answer is too), Tobi and Kabuto. Tobi's Space-Time , Izangti, brilliance , & bijuus he has control of. Tobi also pocesses Hashirama's cells too. Tobi and Madara are very similar. It's just that as of right now there's no way to kill Tobi. This Madara that Tobi's up against can be killed and isn't an Edo meaning no regenerating after a killer blow has hit. No unlimited chakra/stamina. This is just a prediction but if Madara can do most of what Nagato can do with his Rinnegan, does that mean Tobi gets the power of the SO6P , meteor, etc? Remember Tobi has Hashirama's cells too.
Kabuto because of all the Edo's he can summon, Madara won't have the chakra to seal if he can seal, all of the Edo's . Killing the Edo's not an option. Even if kabuto somehow dies the Edo goes on forever unless ur Itachi, meaning Madara will die at some point.
Reason for why i don't say Nagato can def. Madara is because Madara possess
SO6P too but the thread says not including SO6P so Nagato is out of the picture. Reason, SO6P is majority of Nagato's power and not Madara. Madara is strong himself but add SOSP , rinnegan, Mokuton and he's a new being.
Naruto Is debatable. I'm not sure about Naruto it would be a 50/50 because of no SOSP and it's not Edo Madara. But Madara was able to Control Kurama and so was Hashirama with mokuton which Madara now has. So idk aha later on in the series I bet naruto will be able to , maybe even defeat Edo-Madara who knows.
Sasuke cannot. With what we see now from sasuke, he cannot . We haven't seen his true EMS yet so edge goes to Madara. Later on same might happen with sasuke , he'll be able to def. Madara with some upgrade kish puts.
Hashirama, I don't know. My odds for him winning is 49-51. Madara has mokuton and rinnegan, hash has no knowledge on Rinnegan or it's power. Hash fighting and defeating Madara twice knows Madara the best of anyone.
I saw a post saying shisui and kakashi could def. Madara and I laughed. Shisui's KA isn't something to be afraid of in my opinion if AO is able to survive it also Itachi killed Shisui showing shisui isn't much. Not saying Itachi is weak but if he can kill a Madara with EMS, Rinnegan, Mokuton, why couldn't he kill Itachi.
Kakashi would get killed I won't even debate for Kakashi.
And lastly Itachi.. Idk lol Itachi's smart and has seal but no seal so I'd say Madara. Madara has meteor. Kunais prob gonna be useless with Mokuton , Madaras fire tech is on a higher level, BUT Itachi has amatersu and That other move I forgot what it's called and too lazy to look up but requires MS. Idk i score a 48-52 odds for Itachi .
Nagato,
