Ok, guys, I keep seeing this confusion over the Base for quite some time now about if for sure Susano'o requires Tsukuyomi and Amaterasu or not, it doesn't because Sasuke doesn't have Tsukuyomi etc.
You know all these kinds of speculations that circulate around the base.
So here I come with my theory.
1. Susano'o = Tsukuyomi + Amaterasu = Sasuke has Tsukuyomi!
Yes, he does. Why? Because as Kishi mentioned in the Databook, in order to obtain Susano'o, you need to have those two. But he didn't gave any indications about how strong it has to be or how weak. Just that you have to own it.
Now you'll say that Sasuke said that he got the Susano'o by obtaining the double Mangekyo.
Well, let me remind you once again, Tsukuyomi is a Magenkyo Sharingan genjutsu as stated by Itachi himself.
Now the fact that Itachi's Tsukuyomi was stronger, that's a different thing, but it doesn't have to mean that Sasuke doesn't have it and that it's just a mere genjutsu.
a) Sasuke's Tsukuyomi is weaker + it's not his style. Because it was Itachi's style to use Tsukuyomi, it doesn't mean it has to be his own.
b) Sasuke has Tsukuyomi otherwise he wouldn't be able to obtain Susano'o. But why is his Tsukuyomi different and looks like a genjutsu? Because he still hasn't mastered it the way Itachi did, he still can't control the time and space in his Tsukuyomi as Itachi, but, once again, this doesn't mean he doesn't have it.
Now probably you'll ask about Madara Tsukuyomi with one eye, I guess. Well, as Madara said, the answer to this is Hashi's DNA, again...
However, in my point of view it could've been a simple genjutsu, in order to explain better the Tsukuyomi genjutsu.
But Madara is a special case here.
Last but not least, let us not forget from where the Susano'o came. In the japaneese mythology, Amaterasu and Tsukuyomi were Susano'o's brothers. So by common logic, Susano'o wouldn't exist without "his brothers."
2. Sharingans in different hosts get the same power.
As we can see, we have pretty evident proof.
1. Shisui Uchiha -> One eye on Danzo => Kotoamatsukami
-> One eye on Itachi => Kotoamatsukami.
2. Obito Uchiha -> One eye on his own => Kamui
-> One eye on Kakashi => Kamui.
So, from here it's pretty safe to assume the fact that if the eyes aren't together, they don't develop different powers, they develop the same power on both of the hosts.
Hope I made myself clear and that all the questions have been answered.
However, if you're not clear on something, just let me know and I'll explain again.
