Naruto - Tsukuyomi

 Tsukuyomi : Also known as the moon god, Tsukuyomi is a attack that puts its opponent in almost unreleasable genjutsu. What seems like days is only  seconds while under Tsukuyomi genjutsu. The Mangekyo Sharingan attack causes severe mental damage to their opponent  and usually the opponent ends up fainting.  Inorder to resist the attack you need a Sharingan. It’s true that the Sharingan can resist Tsukuyomi but not totally according to Itachi Uchiha. The Technique uses a great deal of chakra and is dangerous to the Mangekyo Sharingan users eyes unless you possess  the Enternal Mangekyo Sharingan.
