Before i get flamed lol i am referring to EMS Madara
the current madara would prob wipe the floor with anyone (BM Naruto and Rinnegan Obito with 6 bijuu is debatable)
The reason i say this is because most of his current power is because of hashirama.
Without Hashirama's power Madara cannot use rinnegan, wood release or perfect susanoo.
the reason i say he would not be able to the rinnegan is because the only 1 before madara who had the rinnegan was the sage of the six paths who was the senju and uchiha in 1. after the EMS senju dna is mot likely needed and obtaining hashirama's dna enabled him to awaken the rinnegan.
the reason i say he would not be able to use PS is because, well let me correct myself and say he would be able to susanoo but it would not be as strong or as big as his perfect 1. this is because susanoo is formed through the materialisation of the user's chakra and as such differs in appearance, as well as colour between users. uchiha were not known for their massive chakra reserves whereas the senju and uzumaki were. meaning that a uchiha with the MS or EMS would have a susanoo the size of sasukes/itachis whereas an uchiha with senju dna would have 1 like madaras. we know that hashi's power is capable of making a technique that can only be used every 10 years be used a few times a DAY.
when u think about it if madara could use PS without hashirama's power then how the hell did hashi beat PS and Kurama at the same time? madara prob would not even summon kurama if he had PS.
So when u think about it EMS madara is probably only as strong as (or maybe even weaker than) EMS Sasuke as he can use Susanoo as well as Amaterasu and Tsukuyomi which madara has not been shown to use yet?
