Sharingan
Description: This Doujutsu (eye skill) gives one the ability to read Genjutsu, Taijutsu and Ninjutsu and then defeat it. As such, the clan member can view a technique being performed and almost instantly memorize the movements required to be able to complete it, including the needed chakra moldings and seals used. However the clan member cannot copy techniques that are unique to another bloodline and the clan member must have a body capable of meeting the chakra and physical requirements to do the jutsu.
Limit: Uchiha Clan.
?[1] One Tomoe
Description: The single tomoe version of the Sharingan gives the user the ability to track a user?s movements better, giving them both an accuracy advantage and pre-emptive recognition of incoming attacks. It lacks, however, many of the truly impressive abilities of the Sharingan.
?[2] Two Tomoe
Description: Along with the ability to track an opponent?s movement, the two tomoe Sharingan gives the user the ability to copy techniques and pierce an opponent?s body with their gaze to see their chakra. The two tomoe also gives the user some defense against Genjutsu.
?[3] Three Tomoe
Description: This version is the highest of the typical Sharingan forms. It gives the user the ability to predict movements by just the slightest muscle tension. The user can copy techniques with greater accuracy as well as defend against Genjutsu of higher level.
?[4] Mangekyou Sharingan
Description: The rare Mangekyou form is a unique evolution of the Sharingan beyond the three-tomoe form. Aside from being the most advance, giving the use the ability to copy almost any technique with ease as well as defend against some of the highest forms of Genjutsu , it also gives the user the ability to access the Amaterasu, Tsukuyomi, Sussan'o, and Susanowo techniques.
