Orochimaro and Kabuto should have the 1st Hokage (Hashirama's) DNA so why didn't Kabuto revive him! I'm sure Hashirama would be stronger than the time Orochimaro revived him!
its imposible.
his soul is sealed with the the death reaper sealing jutsu because of the 3rd hokage and tobirama is sealed too so both are imposible to be resurrected and minato too because he sealed himself soooo here you go the answer to that question
