Obito will fall to Gai and Kakashi, they will have some sort of special moment where Obito will see the error of his ways and die a peaceful death. Madara will look over and see it as a pity someone with such talent and drive could fall so easily and be susceptible to past feelings. There will be a flashback as to how Rin died... If she even died that is. Naruto and Bee will struggle with Madara. Orochimaru and Sasuke will appear on the battlefield to turn the tides with whatever information they got from the scroll Suigetsu found. Madara will be sealed. Naruto will face off against Sasuke in one epic finale. Naruto will kill him and go on to become Hokage. For Tsunade was split in half by the waist, she'll succumb to her wounds after saving the other Kage if she can, then dies a slow death.. Meets Dan in wherever they go, meet her Grandpa. Die happily knowing the war ended in the Shinobi's favor. Madara isn't a powerhouse, he's just a man who has years on everybody he's faced except Hashirama. He knows things, how techniques work, how people work. Play the psychology card. Madara is smart, unlike the trigger happy children he's had to face thus far in his return. Perfect example: Kabuto bragged about being the most powerful ninja, he was done in by Itachi... Who might I remind you said he was the perfect match against Kabuto and was the only one capable of stopping Edo Tensei. Madara is no different. Throughout history the biggest falls happen to those who had the biggest egos. Napoleon. Hitler... And so on, Madara is an idea based on these failed dead men. You'll see. For all we know... The secret on the scroll might be how to ressurect Hashirama. The one and only indefinite powerhouse. With him, you can conquer the planet literally through his Wood Style. Madara lacks that capability.
