Seriously though, if anybody's 'pulling shit out of their ass', it's you. You've got 2 shaky reasons, Danzou is old and he doesn't agree with Shodai's philosophy. You also seem to think that Madara's powerful enough to cast genjutsu on an entire village non-stop for at least 70 years without anybody picking up on it, which is batshit insane.
Honestly, why can't Madara just be Madara? Why does he have to be every person to appear in more than 3 panels?
