Even by Uchiha standards, Shisui was noted to be one of the most talented members the famed clan ever had. Danzō even hailed him as the strongest Uchiha of his time. His abilities allowed him to rise to rank of jōnin four years into being a shinobi and eventually a captain of his own squad. His prowess was so widely known that an entire squad of Kiri-nin quickly chose to flee upon learning of his presence rather than to confront him. A further testament to his prowess is the fact that Kabuto Yakushi wanted to reincarnate him for the upcoming war but was unable to find a sufficient DNA sample for it.
