This thread is not exactly ground breaking stuff but the point I wish to make here is that the Mangekyō Sharingan's abilities are all the same its up to the user and their skill that decides how they are exercised.
There seems to be some confusion over Madara's, Itachi's & Shisui's MS Genjutsu abilities which I wanted to clear up once and for all. If you look at the base Sharingan's abilities it has 2 main parts.
- "The Eye of Insight" which deals with the ability to see chakra , copy jutsu & predict motion.
- "The Eye of Hypnotism" which deals with the innate visual based Genjutsu abilities to manipulate opponents.
The Eye of of Hypnotism part is where the MS Genjutsu of the 3 vary based on their particular skills and innovation comes from.
Madara's MS Genjutsu = Seems to place the person under total control the same way he subdues the Kyuubi to be totally under his control with no free will.
Itachi's "Tsukiyomi" = Allows him to manipulate the victims perception of time so that a mere few seconds can be perceived as days.
Shisui's "Kotoamatsukami" = Subtly hypnotizes the user by placing subliminal commands in their sub conscious that allows them to be manipulated without knowing it.
Sasuke's skill in Genjutsu is lower than these 3 so his MS genjutsu is not very defined in any one area. He has show a mixture of abilities like forcing a shinobi to spill information by placing them under his control and using it to torture KB with imaginary spikes through his body. He could create his one unique version of Genjutsu manipulation but since Sasuke is more a Ninjutsu type he shows more skill with Amaterasu & Susanoo.
The MS version of Genjutsu are more powerful than the base Sharingan's but the abilities are essentially the same as we have seen Kakashi using subtle hypnotism on Zabuza to force him to make hand seals that he could then copy. This is essentially the same skill Shisui uses but Shisui's is at a more refined level.
Just as we have seen Itachi place a woman under his control to distract Jiraiya or Sasuke using his to control Manda both of which is similar to Madara's style MS to over take the victim subduing their will.
So the end point is they all have the same base ability it just depends on their skill and style of Genjutsu which determines how they use it.
