Oh yeah, Madara's Perfect Susano'o possibly could because he did state its power to be equal to a tailed beast and would have needed to have fought that to be able to test that hypothesis, meaning he may have tanked even Kurama's TBB.
By tank if you without any protection then;
Suigetsu
2nd mizukage
Kabuto
With protection;
Madara - perfect susano
Itachi - Yata mirror
Karum's TBB drawee karma himself at full power and it's explosion can engulf more than 10 mountains.
Madara would have fought Kurama at VOTE and unless he was talking rubbish or comparing it to another tailed beast, it is possible he could tank it.
I kind of agree, why kabuto?
Madara has a chance yes, but why itachi?
I would the yata shield seal the TBB or something?
If not the explosion would surely engulf itachi.
By dwaree I meant drawf.
Also you are right he likely did fight it, karuma may have been his on doing.
Also karuma could have been sealed instantly into mito because a blast from him would effect everying with in atleast 100 acres.
