Tsukyomi is one of the hidden abilities of the Mangekyo Sharingan to cast an intense genjutsu on the opponent where the person can warp space and time and their reality. To be able to use this technique you have to unlock the Mangekyo Sharingan. Only two users are known to have used it. Itachi Uchiha was able to completely control time and space and is the only one to be able to do so. Sasuke Uchiha was said to be able to use this technique but can't completely control time and space. This technique uses a lot of chakra. Itachi was shown to be exhausted after using it twice on Kakashi and Sasuke.
