"You know what they say, don’t you Naruto…When two Shinobi are powerful enough…They read each other’s thoughts, simply through an exchange of fists. Without ever uttering a single word…Get it. You’ve always been naive…Naruto. Tell me…Do you know my thoughts? Can you tell what’s on my mind?"
Sasuke Uchiha (うちはサスケ, Uchiha Sasuke) is one of the last surviving members of Konohagakure's Uchiha clan. After his older brother, Itachi, slaughtered their clan, Sasuke made it his mission in life to avenge them by killing Itachi. He is added to Team 7 upon becoming a ninja and, through competition with his rival and best friend, Naruto Uzumaki, Sasuke starts developing his skills. Dissatisfied with his progress, he defects from Konoha so that he can acquire the strength needed to exact his revenge. His years of seeking vengeance and his actions that followed become increasingly demanding, irrational and isolates him from others, leading him to be branded as an international criminal. After learning the truth of his brother's sacrifice and later proving instrumental in ending the Fourth Shinobi World War and being happily redeemed by Naruto, Sasuke decides to return to Konoha and dedicates his life to help protect the village and its inhabitants becoming referred to as the "Supporting Kage" (支う影, Sasaukage, Literally meaning: Supporting Shadow).
Like his older brother Itachi, Sasuke is recognized as a natural prodigy of the Uchiha clan, graduating at the top of his class in the Academy. He makes a strong impression on Kakashi Hatake in the bell test and fights on par with strong shinobi, such as Haku and Gaara in Part I. Powerful individuals have noted of Sasuke's great potential: Orochimaru offers to help drastically increase his power; Madara Uchiha notes that he would have liked to recruit Sasuke had he only been born a few years earlier. Under Orochimaru's tutelage for two-and-a-half years, Sasuke becomes strong enough to fight members of Akatsuki, such as Deidara and Itachi, two of the Five Kage, and defeat Danzō Shimura, one of Konoha's strongest ninja. With the Six Paths Chakra, he could help overwhelm Madara as the Ten-Tails' jinchūriki, and Kurama compared Sasuke's prowess to that of the Sage of Six Paths. As an adult, despite losing his left arm, he could defeat all the kekkei genkai shinobi of the Coliseum without using his Sharingan, and years later, could fight on par with Kinshiki Ōtsutsuki. As such, he is regarded as a legendary shinobi who could possibly take on the entire world in a fight. The only individual capable of defeating Sasuke is Naruto.
Sasuke can placed anywhere between Inbetweener and Planetary, boasting a Perfect Susano'o, a Rinnegan and Mangekyo Sharingan, the Amaterasu along with Blaze Release, multiple forms of elemental control, etc.
