^ But that's my point: neither EMS Madara or EMS Sasuke were shown to use Complete Body Susanoo alone in the manga. The only times when they used something similiar to CB S was when they used MA:S with Kurama, whose chakra can enhance ninjutsu. And like I said above, Indra was said to inherit Hagoromo's "eye's, spiritual energy and powerful chakra", which could be some form of Six Paths Chakra, not necessarily complete form of it.

So again, using Complete Body Susanoo through EMS alone isn't as 100% certain as many would like to believe. I'm willing to give big maybe, but that's it.
