Shin Uchiha

He is a hooded man, whose goal is to eliminate Sasuke Uchiha. He is also the father of Shin Uchiha.

Personality
He loathes Sasuke Uchiha and plans to kill him for both murdering Itachi Uchiha and "bringing shame to the Uchiha clan". To achieve that goal, he is willing to sacrifice innocent bystanders like Sasuke's daughter, Sarada Uchiha. He also appears to want to revive Akatsuki.

Appearance
He first appears garbed in a dark, hooded cloak, later discarding it to reveal a dark, long-sleeved, high-collared shirt bearing an Akatsuki cloud emblem on both its front and back, as well as dark pants and boots. He is bald and has at least ten Sharingan implants, visible on his head and left arm, as well as Sharingan in his left and right eye sockets. A horizontal scar runs from his right temple to the bridge of his nose, over his right eye, which is held open by eight stitches; the sclera of his right eye appears dark and bloodshot.

Abilities
His abilities are still largely unknown. However, given that he possesses multiple Sharingan, it can be reasoned that he is skilled in using the dōjutsu and its enhancements. He also owns an unknown creature that resembles the miniature Ten-Tails spawns with a Sharingan and is able to share vision with it and others.

Sharingan
This man possesses multiple fully-matured Sharingan implanted into his head and left arm. Thus, it can be inferred that he is highly advanced with these eyes, having them constantly activated while showing no signs of tiring. With them, he has heightened perception, able to perform various complicated attack patterns.

Mangekyō Sharingan
Through unknown means, he was able to awaken the Mangekyō Sharingan with an identical pattern to his son and spying creature. With it, he was shown to be able to telekinetically manipulate and launch objects. Using his right eye, he has some form of Space–Time Ninjutsu.

Naruto Gaiden: The Seventh Hokage and the Scarlet Spring
With the intent to eliminate the disgrace of the Uchiha clan, he tasks his son Shin to spy on Sasuke. After their brief scuffle, Shin returns to his father. After finding out that Sasuke's daughter, Sarada Uchiha, left Konohagakure, he orders his son to abduct her. His spy creature appears telling Shin to retreat against the Hokage, to which it used Space–Time Ninjutsu and took Shin along with him.

Later, ready to begin his next attack, the man called forth Shin and six copies of him, before using his creature to teleport them. They arrived above Naruto and Sarada and attacked. After Naruto easily repelled the attack, Sasuke appeared to aid Naruto.
