Re: Sasuke's true MS jutsus
I don't think the english translation is correct. I've posted a few threads on this topic before.
According to Narutopedia:
In my opinion, Amaterasu, Tsukiyomi, and Susano'o are the basic MS techniques. I think Kakashi's is different because he is not of Uchiha blood. just my speculation. I think Itachi injected his powers into Sasuke, but it was a one-time thing to trigger when he catches sight of Tobi's sharingan. This was evident because it was Itachi's MS pattern shown when Amaterasu involuntarily fired off. After that incident, Sasuke seemed to have his own MS pattern from the realization that Itachi was only being a good brother.
In chapter 397, on page 11, Madara tells Sasuke: 「最後…お前のために己の瞳力をお前の中へ注ぎ込んだのだ」 ("Saigo... Omae no tame ni onore no dōryoku wo omae no naka he sosogi konda no da"). Translated to English, this would become: "At last... For your sake he injected his own eye power inside you". He never says "all eye powers," which means it's still unknown whether or not Sasuke can actually use any of Itachi's other jutsu, besides Amaterasu. In fact, it's also unknown if that Amaterasu was anything more then a one-time thing.
For the sake of argument, let's say what you think is true.. the idea that all of the MS techniques Sasuke has been using up till now are really just Itachi's... then why would Madara put Sasuke into certain situations to draw out Sasuke's Susano'o? Could Madara really predict that Itachi would give Sasuke all of his own MSM techniques? or is it that Madara expected that all MS users could wield Amaterasu, Tsukiyomi and Susano'o?
