Uh, Itachi did deactivate his Sharingan multiple times. I think alot of people would agree to that. "Never" is a strong word. And I'm not saying Madara ISN'T an Uchiha. Read the thread again if you have to.this thread is somewhat pointless. i will admit that you're probably first to mention it. but saying that he isn't an uchiha or that he isn't the real madara is mere speculation. Itachi is a real Uchiha and he never deactivated his sharingan(if you dnt count the flashbacks). when itachi sought help on assassinating the uchiha clan he looked for madara. plus if he wasn't madara or for that matter an uchiha how could he possibly know half the things he does know. not to mention if i remember correctly madara created zetsu. as for the wall of sharingans they are probably apart of his plan which we still don't know about completely.
so to put it simply, until kishi tells us he's not the real madara.HE IS!!!
I'm saying there is a POSSIBILITY that his Sharingan may be transplanted, because we haven't seen him deactivate it at all. If the thread seems pointless to you, no point in commenting
