Uchiha Sasuke

Sasuke Uchiha (うちはサスケ, Uchiha Sasuke) is a main character in the Naruto series. He was originally introduced as a protagonist, a member of Konohagakure's Team 7. As the series progressed, he became an antagonist, culminating in his association with Akatsuki, becoming one of the most dynamic characters in the series. Sasuke is currently amissing-nin, an international criminal, and most likely the last surviving member of the Uchiha clan.
 As a child, Sasuke grew up in the shadow of his older brother, Itachi Uchiha who was an acknowledged prodigy viewed by the Uchiha clan as a genius, and whose work would further strengthen the bonds between the village and the clan. 

Personality


When he was a child, Sasuke was a very kind boy, loving towards his parents and brother, and respectful to his fellow clansmen as well as his teachers. He was even very proud of being Itachi's brother and Fugaku's son, famous for being devoted protectors of Konoha, and he always desired to emulate them. 
When first introduced to Team Kakashi, Sasuke displayed great indifference to his team-mates. Feeling superior to all of them, including his teacher, Sasuke was unwilling to cooperate with Naruto Uzumaki or Sakura Haruno, as he felt they would provide him no aid in killing Itachi. However overtime, as he spent more time with his team, he begins to see them as somewhat of a family and Sasuke starts to lose some of his anger, caring more about his team than his revenge. Sasuke even admitted to Naruto that he almost thought that he should forget revenge and instead focused on Team 7. To help push him back into his desire for power, Orochimaru branded Sasuke with the Cursed Seal of Heaven during the Chūnin Exams to give him a taste of power. Although Kakashi Hatake sealed the Cursed Seal, as well as teaching him the Chidori in the hopes of deviating him from the path of revenge, Sasuke began to draw more power from the seal in the hopes of getting stronger.

Abilities

Sasuke is established as a genius, even by the battle-excelling Uchiha clan's standards at the series' start, excelling at all that he does and finding little difficulty in more challenging tasks. 
By Part II, he develops much of his potential and becomes a very powerful ninja, strong enough to fight on par with several highly skilled shinobi. Admittedly, in his battle against Orochimaru, Sasuke downplays his victory, and attributes it to Orochimaru's sickly state.According to Tobi, Itachi had already determined the outcome of their fight, and was sick as he was using medicine to prolong his life. This didn't prevent Itachi from praising Sasuke however, saying if he didn't use Susanoo he would have been killed by Kirin. However, Sasuke managed to survive a fight with Deidara, a powerful and dangerous S-rank ninja well known for his abilities, without any form of handicaps. After receiving his Mangekyō Sharingan, Sasuke proved capable of holding his own against at least two Kage and their bodyguards, before being weakened to the point of exhaustion due to his battle with them.
