i'm just thinking He was a senju and they had the Body of the S06PI think he never expected to use all his eyes in one fight, and that he only had the firsts dna because he was awsome, and maybe he wanted his wood element?
I dont think the first had healing element, unless maybe he did, and after his fight with madara he healed him and told him he would let him live aslong and he disappearded and never returned to the village? then he told everyone madara was dead?
so massive amounts of chakra and the will of fire and if Naruto is a foreshadow of being senju i think it fits perfectly ... (but of corse he has the fox LOL) i do not think danzo is so stupid to just release his arm and go ape within the frist 3 seconds lol hahaha
and like i said i'm assuming the eye in his head is closed cause he cannot yet use it so there is a recharge that oro figured out and implanted it into danzo but oro knew that having a uchiha Body along with the eyes makes you Godly like itachi where you are soo awesome you have to throw fights to show everyone your a mortal still hahahaha
