During Naruto,Killer bee,edo Itachi -edo pain arc,the fight didn't last long but pain was quite the fearsome opponent after Kabuto took complete control over him but that is not the point,the point is that he was sealed with the sword of totsuka by Itachi
This sword has never failed whenever itachi brought it out,but the fact is that edo Itachi is long gone nd the sword is part of Itachi's arsenal so i guess it isn't possible to defeat Madara with it or is it possible to bring back the sword of totsuka?
