Shin Uchiha (うちはシン, Uchiha Shin) was a former test subject of Orochimaru. After developing a fixation on the Uchiha clan, more specifically Itachi, he took the Uchiha name for himself and severed ties with Orochimaru, taking his "sons" with him. Believing that peace was detrimental to human evolution, Shin began a plot to revive the Akatsuki so that the ensuing conflict would be a catalyst to further his beliefs.
