This is the best and most Believable theory for the war that I've read on NB.ABOUT THE SUBSTITUTE MADARA IS GOING TO USE....
Agree with you 100%... continuing with your thought...
You all may recall this is the same statue that Pain used when he was teenager after Hanzo caused Yahiko to kill himself. At that time Pain only used the head and a relatively small portion of its body....but he still wipped the map clean of all enemy shinobi...Danzo lifted up his girly miniskirt and ran home (disappeared) and Hanzo used a Transportation jutsu to escape as well.
With the statue filled with 7 tailed beast chakra he can pretty much end the entire war and wipe out everyone on the battlefield like Pain did before. The difference is that Pain had to be connected directly to the statue and it took chakra from him directly through the rods.
MOST LIKELY THIS IS WHAT MADARA NEEDS TO STEAL A SUBSTITUTE FOR SO THAT SOMEONE "EXPENDABLE" CAN BE LINKED TO THE GEDO STATUE THRU THOSE CHAKRA RODS. OF COURSE THIS FODDER PERSON WOULD BE CONTROLLED VIA THE SHARINGAN OF MADARA SO HE STAYS OUT OF DANGER. AND OF COURSE HE WOULD USE THIS PERSON TO THE MAX UP TO AND INCLUDING SACRIFICING THIS PERSON... THEN ONCE HE WIPPED THE BATTLE FIELD OF ALL JOINT SHINOBI ARMY HIS PLAN WOULD BE TO BATTLE NARUTO AND/EIGHT TAILS TO SUCK OUT THEIR HOST CHAKRA WITH SOME SPECIAL JUTSU AND THEN AT THE LAST MINUTE PUT HIMSELF IN PLACE TO BENEFIT AND BECOME THE ULTIMATE 10 TAILED BEAST. THEN OF COURSE HE WOULD PLAN TO EXECUTE HIS MOONS EYE PLAN ....(AFTER AN EVIL/SINISTER SNEERING SMILE AND TAUNT THAT HE IS INVICIBLE AND NO ONE CAN STOP HIM SINCE HE IS THE ULTIMATE POWER NOW ETC ETC ETC.)
Cant completely figure out how our two hero's are going to do battle with Madara using this Gedo Maze with 7 sealed chakras vs their two. But somehow we know they will prevail.
Just remember that gedo thing is not being brought out to just stroll through the park....some heads have got to roll, literally! Goods guys gotta start dying now.
My thoughts at least for now....Let me know your thoughts on this one please. Would appreciate some feedback but not attacks guys.
I would love for someone to prove this theory wrong other then Kishi own story.
