To modify and continue what Seelentau is saying, a databook stated the "Tsukuyomi + Amaterasu = Susanoo" equation. At the time, Itachi was the only known user of Susanoo. And that same databook said Tobi is Madara. That databook is outdated. Many users have accessed Susanoo without the usage of Amaterasu and Tsukuyomi. Read the last page of chapter 464. The manga stated that two powers unlocked in both Mangekyo Sharingan (called the "Double Mangekyo" by Sasuke in that chapter) are required to unlock the third power, Susanoo. This was later verified in chapter 688 by Kakashi. The two powers Sasuke unlocked were Amaterasu in his left eye and Kagutsuchi in his right. The two Kakashi had were Kamui in both eyes. Shisui had Kotoamatsukami in both eyes. Madara and Indra are unknown. Only Itachi unlocked Tsukuyomi in his left eye and Amaterasu in his right. No one else. Do NOT add Madara, Indra, Kakashi, Sasuke, & Shisui as users of Amaterasu and Tsukuyomi. Doing so again after being warned by a rollback like @Tau will lead to a block. That isn't debatable.
