Shinga

is the main antagonist in the arc who only appeared for Naruto Shippūden: Ultimate Ninja Heroes 3.

Background
Having left Konohagakure, Shinga was a traitor to Konoha. He once worked as a scientist under the command of the Third Hokage, Hiruzen Sarutobi. With the help of his two subordinates, he found a new technique of untold power, the Jibakugan. Only Shinga knew how to control this technique and he gained a lust for power. He created the demon, Shinki, which drains chakra from the land. The Third Hokage heard of Shinga's new discovery and felt that the technique was morally wrong to use on others. He banned the technique, making it a forbidden technique. The Third then dispatched Itachi Uchiha to arrest Shinga, but he was able to escape for they could not find his body in a mudslide. Years later, when Shinga sees Sasuke Uchiha's eyes, he believes that he is Itachi.

Abilities
Shinga was once a brilliant scientist, creating a new technique called the Jibakugan. Using this technique, he could bring out the victim's negative or hateful emotions within their subconscious, and use them to his advantage. He commented that the Jibakugan was "stronger than hypnosis" and irresistible, but Naruto Uzumaki was able to resist it. When merged with the Shinki, Shinga gains a slew of other powers, including the ability to steal chakra from others en masse.

Plot Overview
Shinga retrieves the demon seed, Shinki, from the Konoha Sealed Hall and merges with it. This results to Tsukigakure being wrapped around by a tree. He is later killed by the combined efforts of Naruto Uzumaki and Sasuke Uchiha.
