No... each ms eye gives the user a technqiue and with both eyes the user gains a third and final technqiue, in itachi's case it was amaterau, tsukuyomi and his final technque was susanoo.
Also each ms gives the user a different techniques. Itachi's ms cannot use koto matsu or kumai, nor can shisu or kakashi use any of itachi's ms technqiue the only reason sasuke seem to have itachi's technqiues is because he implanted it in him before be died
Wrong. Each user possess different MS technique ... only those lucky to awake Amaterasu and Tsukuyomi are able to awake Susanoo and even that is not 100%
In other words, most MS users have just 1 eye power and each user has a different one. Some have 2 (Amaterasu and Tsukuyomi) and are able to awake the 3rd Susanoo but its rare as Madara said. Also Itachi did not implanted his MS powers into Sasuke. He just scripted his amaterasu to strike Madara on sight. It was just one-shot thing. They possess the same powers because they are brothers.
Itachi's right eye posses tsukuyomi and his left amaterasu.
Whilst with sasuke amaterasu is in his right eye and he has the power to manipulate it which is in his left eye
this is right, but Sasuke's left eye possess Tsukuyomi as well
so shisui eyes have the same abilty ?
yeah
There is no doubt at all that he used KA at the summit.
yes
Since the only MS users with both eyes we have seen are sasuke and itachi, I think that its cannot be concluded that every MS gets its own technique, especially since sasuke and itachi have the exact same techniques as one another.
-Obito/Kakashi possess just Kamui
-Madara and Izuna were never mentioned as users of Amaterasu, Tsukuyomi nor Susanoo
-Itachi and Sasuke have similar eye powers cause they are brothers
-Shisui's eyes both possess just 1 and the same power
So in other words, most MS users have/had just 1 eye power unique to them.
But some are lucky to have 2 which are Amaterasu and Tsukuyomi and are able to awake Susanoo if lucky.
Proof ? Izanagi washed his face and Amaterasu,Tsukuyomi and Susanoo were born. No Obito/Kakashi's, Shisui's nor Madara's eye powers : )
And manga, databook and common sense
