Riyoki Uchiha

Riyoki is the second eldest of the Uchiha Brothers. He is the most skilled of all brothers. He passed the Academy at the age of 5, mastered his Sharingan at that same year, was promoted to Chunin at the age of 7, was promoted to Jonin at the age of 9 and mastered his Mangekyo Sharingan when he was just 12. He is killed by Kakashi Hatake. Riyoki is the only Uchiha to have mastered the Ultimate Sharingan Eye. The Ultimate Sharingan Eye is said to be far stronger than even the Eternal Sharingan. Thus, he is the strongest Uchiha Brother, but Madara is stronger as Madara has more jutsu skill.



The Ultimate Sharingan allows the user to see at the speed of even 1/1,000,000th of a second, allowing the user to dodge any jutsu (even Taijutsu) and can copy Taijutsu as well, which the normal Sharingan was unable to do. Further mastering the Sharingan allows the user to see through any genjutsu and even stop it, including Tsukiyomi.
