Shin Uchiha (Clones)

The is a mysterious young shinobi garbed in the attire of the Uchiha clan. His identity and origins are currently unknown, though Kakashi Hatake suggests that he may be a survivor of the Uchiha clan or, more likely, one of Orochimaru's experiments.

Personality
He is quiet and enigmatic. When he does speak he does so in a stilted, monosyllabic manner. Outwardly emotionless, he nevertheless expresses a desire to avenge Itachi by killing Sasuke, declaring that Itachi's murder was unforgivable.

Appearance
This boy is an eerie-looking young man. He has an indistinct hairline, and his light-coloured hair is slicked back and tapered to a point. He lacks eyebrows and wears a perpetually wide-eyed expression, displaying a pair of active Sharingan. When confronting Sasuke Uchiha he donned a dark, hooded cloak. Beneath the robe he wears a light-coloured, high-collared kimono shirt with an Uchiha emblem emblazoned on the back and a wide obi wrapped around his waist. He wears dark arm-guards that cover his forearms, dark pants, and a pair of dark open-toed boots with distinct zig-zag treads.

Abilities
In his debut, he showed a wide range of skills such as the Body Flicker Technique which employed leaves to cover his escape. He also displayed skills at wielding a kusarigama to trap his opponent with a two-pronged attack.

Sharingan
He possesses a pair of three-tomoe Sharingan. Though much of its use has not been seen, it does grant him heightened perception during battle.
