Sasuke has always been able to grasp most ninja abilities with ease. When Naruto begins Sasuke is highly proficient with the Uchiha clan's signature fire-breathing and weapon-based techniques, talents he continues to hone throughout the series. Of the abilities gained through his Uchiha lineage, Sasuke most commonly uses the Sharingan, an ability manifested through the eyes, that grants him a variety of advantages. Sasuke's Sharingan develops for the duration of Part I, first only allowing him to track fast-moving objects and culminating with his ability to predict the movements of others. In Part II he starts to use his Sharingan to cast illusions, allowing him to manipulate and confuse others. Sasuke's Sharingan reaches its peak after Itachi's death; through the death of the person closest to him, Sasuke awakens his own Mangekyo Sharingan, gaining most of Itachi's techniques.
Orochimaru's influence is also a recurring element of Sasuke's abilities. During their first encounter in Part I, Sasuke is branded with a cursed seal, which grants him a brief surge in strength and speed when active. Sasuke's various uses of the seal cause him to crave more of its power as he enters to a second level amplifying the effect and drastically changing his appearance. Itachi removes Orochimaru and the cursed seal from Sasuke's body during their final battle. When Sasuke begins to train under Orochimaru, his physical abilities are greatly enhanced and he learns how to summon snakes so as to help him in battle. In addition to the techniques taught to him, Sasuke gains access to some of Orochimaru's more common abilities during the period he absorbs him into his body; Sasuke is able to recover from injuries in short periods of time and can regurgitate new bodies for himself.
Prior to Sasuke's defection, his teacher, Kakashi Hatake teaches him how to use the Chidori, a collection of lightning-based chakra in his hand that serves as a rapid thrusting attack that severely damages any target. While Sasuke is able to use the Chidori twice per day during Part I, his usage of the attack in Part II is unknown. Instead, Sasuke employs variants of the technique, using the fundamentals behind the Chidori to create a number of new abilities. Sasuke's first display of such an ability involves emitting electricity from his body as a shield and then sending it along the blade of his chokutō to increase its cutting potential.He later proves able to mold electricity into more solid forms such as extendable swords, and even harnesses natural lightning to use it as an attack named Kirin.from : wikipedia
