Talking about the one Kabuto summoned last that made Madara pee a little.
when i first thought about it i thought it was Rikudo(spelling) sennin, then i thought it was Minato. but now after weeks of thought i think it may be Madara himself. i mean shouldnt he be REALLY old or something? then this obito theory came into my head which Zetsu could have helped fuse the old madara with what was left of obito
This is my first post btw and i hope everyone will learn to like me, as i am hilarious
