When discussing the Sharingan, it is clear that its most prominent ability is being able to imitate many different types of jutsu.
However, there is one point that makes many people curious here: they do not know exactly how this eye imitates ninjutsu?
As we also know in Naruto, to perform a jutsu, the user must skillfully control his chakra and may include some hand chanting techniques.
Basically one of the Sharingan’s abilities is to be able to see faster than the naked eye, thanks to which the user can see and remember the handprints of opponents `recorded` in their eyes.
But there is a notable point: users of the Sharingan eye may not be able to copy jutsu perfectly.
Besides, Sharingan users cannot copy jutsu that have unnatural elements.
And there are some jutsu in particular that almost certainly cannot be imitated by Sharingan users.
Examples include the techniques of Yamanaka, Nara and Akimichi.
Above is the explanation and limitations of the Sharingan eye when imitating ninjutsu.
