Naka Uchiha

was a shinobi of Konohagakure's Uchiha clan.

Background
Naka was a close comrade of Naori Uchiha. He was able to awaken his Mangekyō Sharingan and became obsessed with the technique Izanagi, which he used to kill some of his own clansmen. In order to save him, Naori used Izanami on him to force him to accept the truth, and see reality. After struggling for a while, Naka eventually accepted his fate and broke the loop caused by the Izanami.

He presumably died at some point either before or during the Uchiha clan massacre, along with the rest of the Uchiha clan.

Appearance
Naka had grey chin-length hair, and wore the typical attire of the Uchiha clan which comprised of a high-collared shirt with the clan's symbol emblazoned on the back, a Konohagakure forehead protector, and a variation of the village's flak jacket which more closely resembled the one worn by ANBU; it had a pouch on the left strap, and no band woven around the waist. Accompanying this was a large equipment pouch and a tantō strapped across his lower back.

Abilities
Naka was at least skilled with kenjutsu, considering he had a sword. He was able to awaken his clan's dōjutsu kekkei genkai: the Sharingan. The dōjutsu granted him the ability to use the technique Izanagi, which he apparently used obsessively with such skills that he could survive combat against several other Uchiha. He was also able to activate the Mangekyō Sharingan, which took the form of a red, three-point pinwheel with his pupil being prominent in the center.
