The reason being that Danzo's right arm seems to be severely injured and his right eye, the sharingan, seems to be a transplant which means he lost his right eye at some point and we all know from Kakashi the side effects the sharingan has on someone who is not an Uchiha. Side effects that are probably even worse for a man Danzo's age.Originally Posted by RasenDori
So let's suppose that Danzo is not Madara. It would make sense that someone who was once strong enough to go toe to toe with Sarutobi when he was in his prime would want access to Orochimaru's research in order to restore his body. Someone who was that strong already wouldn't need a borrowed sharingan.
On the other hand if Danzo is Madara why would he want to restore his right arm and eye? Madara's right arm is fine and his right eye seems to be his only good eye. Also why would he risk possibly exposing himself by using the black ops to acquire Orochimaru's research data when it was previously implied that Madara's intends to use Sasuke's body or possibly just take Sasuke's eyes once he gets EMS.
Someone really needs to change the title of this thread.
