Madara is just playing until now and his boy Obito is not going all out too like what he did to the mist ninja's

what i'm trying to say is the 4 hokages will not beat madara,obito or the 10 tails

Madara can just use 15 bansho tensei 20 CT and 30 meteors while Obito and the 10 tails are intagible

the only way i think to stop him is revive itachi again

so do you think if oro uses this 4 hokages will even make a difference?
