A trait carried by the Uchiha clan in
naruto. It'
s easily recognisable as the eye goes red, and depending on the user level
will have 1 to 3 dots around each pupil. 1 dot meaning beginer user, 2 mauture user and 3 dots meaning advanced user. Uchiha Sasuke started with 2 dots in the right eye and 1 in the
left. Uchiha Itatchi was the same. Hatake
Kakashi started with 2 dots but because his eye was a transplant he can't de activate it.
The main feature of a Sharigan user is it's abilty to copy Ninjistu, Genjistu and Taijistu just by seeing the technique only once. Hatake
Kakashi has mastered this and has discovered what the Sharigan eye was really used for.
First comes the Form manipulation which is where the Sharigan user uses the eye of insight to copy the opponents movements. Secondly is the Technique manipulation which the Sharigan user uses the insight and the copy
wheel copy technique to copy an opponents justu which combines with the Form manipulation to freak out the opponent. Finaly using the copy
wheel hyponosis technique the Sharigan user hypnotises the oppoent and suggests things that they are going say which means they can copy, this is combine with a genjistu technique and the other manipulations to give the Sharigan user the illusion of seeing into the future, this is
best seen during the first fight against Zabuza
