Well duh Oro will have a part in Madaras downfall. He is helping Sasuke at the moment correct lol. And Sasuke will end up helping Naruto most likely. Son in turn Madara will lose due to the help of Oro but by his hands I think not.
ORO: I will help you Naruto . . . but i have a pricei could very well see that happening but one thing is bothering me. if he said that he has no interest in this war, then why would he even step onto the battlefield? if he had no interest then wouldnt that mean he will not have anything to do with it? i can still see either one of these theories to be true.
You maybe right in the sense that the illusion will probably not work with him (as seen with Sage Kabuto who concealed his snake eye during the battle with him & Sasuke in order to become Genjutsu & Tsukuyomi-proof).I'm betting the illusion won't work on certain ninja's, like Orochimaru. He's probably perfectly OK with most of the ninja world turning into sheep, since they'd be easier to experiment on.
& remember that Madara can only be defeated by the likes of Hashirama. The key word is likes.* Who else in the Naruto universe has spent nearly a quarter of his life conducting research and engaging in internal affairs with Hashirama DNA (giving it to people like Danzo & a whole lot more which have all died upon receiving with the exception of Yamato)?Madara is no longer under the control of edo. He broke the seal.
Lol didn't Orochimaru create him technically???What a great fantasy dream match up!
Madara vs. Orochimaru!
I doubt he would win against Edo Madara, but he'd make him sweat bullets though!
