Shisui Uchiha

Shisui Uchiha (うちはシスイ, Uchiha Shisui), renowned as "Shisui of the Body Flicker" (瞬身のシスイ, Shunshin no Shisui; English TV "Shisui the Teleporter"), was a shinobi from Konohagakure's Uchiha clan and an minor character of the Naruto franchise.

Background
Born into the Uchiha clan, Shisui was noted to be one of the most talented members of the famed clan. At some point in the past, he fought with Ao of Kirigakure who retained an acute memory of Shisui's chakra colour, as well as the Uchiha's ability to control others with his Mangekyō Sharingan's ability.

When Shisui's best friend, Itachi Uchiha, began to act "oddly", Shisui was instructed by the Konoha Military Police Force to monitor Itachi because the younger Uchiha's position in Anbu was instrumental to the Uchiha's future status in Konoha. As the Uchiha continued to grow angrier and more violent from the distrust of the village due to the suspicion of their involvement from the Nine-Tails' Attack on Konoha, Shisui was perplexed that the clan would not deter from the coup d'état that they were planning and Shisui was greatly concerned with the consequences that would follow their actions. Shisui approached the Hiruzen Sarutobi revealing the truth to The Third Hokage. Trusting Shisui, seeing as he is Kagami Uchiha's descendant, Hiruzen allowed the Uchiha to spy on his clan for the village. Ultimately, it was decided that Shisui would use his Kotoamatsukami on Fugaku Uchiha to subtly end the coup d'état plan. Later, as Shisui prepared to make his move, Danzō Shimura, believing that simply manipulating the Uchiha's leader wouldn't end the conflict, chose to take Shisui's eyes for himself in the desire to protect the village in his own way. While Shisui effortlessly subdued Danzō at first, the ruthless elder caught Shisui off guard by using the forbidden Izanagi with another Sharingan already in his possession to break free and steal Shisui's right eye. As Danzō and his men surrounded Shisui to take the left eye, Shisui managed to escape.

Fearing that Danzō was right in Shisui's inability to stop the Uchiha's revolt and that the elder would continue to pursue his left eye as well, Shisui entrusted it to Itachi, telling him to protect both the village and the Uchiha name. In order to prevent conflict from arising over his eyes within the clan, Shisui wrote a suicide note and made it appear as though he had crushed his eyes when jumping off a cliff into the Naka River to kill himself. He, at the same time, was able to erase his existence, leaving no corpse behind. In the anime, Shisui was also hoping to use his death to awaken Itachi's Mangekyō Sharingan.
