we sought that one of kabuto abilities is use other people skills trhu him, with power up given dragon mode, what make it so deadly is that every ability is more powerfull than it originally was, thru oro he might be able to use fuuri no jutsu, if his edo plan is going to fail what stops him making madara's ocular powers his own? that way edo could be stopped and terror of madara will still be alive.. other thing what has puzzled me is, is it necessary to people in question to be dead? if not think this. we know kabuto did study hashirama's genes througly and he did go through trouble to get his hand's to kabuto.. if he can use yamato thru demon twins jutsu we have yet another very strong wood element user in our hands... and this way kabuto could eventually use all elements. as that doton guy shown and kabuto himself stated im closer to old sage than anyone else here now- and he wassn't kidding.. any thoughts?
