Ultimate Mortal Kombat 3

Smoke, unit LK-7T2, is the third prototype cyber-ninja built by the Lin Kuei. He tried to escape the automation process with Sub-Zero but was captured. His memories were stripped away, leaving behind an emotionless killer. However, Sub-Zero believes that within this machine is a human soul trying to escape.

Smoke was once a friend and ally of Sub-Zero when they both tried to escape from being turned into machines by their ninja clan. But, Smoke is captured and transformed into a cyborg with a mission to find and kill his old partner. But Smoke soon finds himself being pursued by Shao Kahn's minions. He learns that he still has a soul and his true mission is the destruction of the Outworld invaders. He defeats Kahn and saves the world but is forever trapped in his artificial body.
