[Discussion] There is one thing I do not get about Madara.

[endo]

Either he just doesn't want to use it, or he doesn't have it. It's also possible for Madara to have his own set of unique MS abilities which he hasn't shown yet either. Like Obito's has Kamui. Shisui's has Koto Amatsukami.

I think to awaken Susanoo, you have to awaken your two unique MS abilities. In which Itachi's where Tsukyomi and Amaterasu.

But it's still entirely possible that he just didn't want to use it just like he hasn't shown any other MS ability.

maybe it's not that he doesnt have it but rather he cant use it.... for some reason I can't think of xd
