Naka Uchiha (Sigma)

was a shinobi of Konohagakure's Uchiha clan.

Background
Naka was a close comrade of Naori Uchiha. He came to develop a Mangekyō Sharingan and he became obsessed with the Izanagi. Naori then used Izanami on him to try and make him accept the truth and see reality and he eventually accepted this and broke the loop caused by the Izanami.

He was supposedly killed in the Uchiha clan massacre along with the rest of the Uchiha clan.

Appearance
Naka had long chin length hair ending in five spikes of hair and a Sharingan.

He wore a Konohagakure forehead protector. He also had a Mangekyō Sharingan. His was similar to Itachi's, though the tomoe that connect to the middle of the pupil are much thicker than Itachi's.

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. He was also able to activate the Mangekyō Sharingan. He was able to use the Izanagi, which he apparently used obsessively.
