Well Normal Madara , only the first Hokage is enough to defeat him .. Edo Madara .. Minato and Hashirama .. Hashirama for the fighting .. Minato only for the sealing part ...
what makes you guys think that edo madara will give the hashi and his bro problems, i mean only hashi on his own can take on edo madara like madara said minato and hiruzen would just be there to watch
