Cyrax is unit LK-4D4, the second of three prototype cybernetic ninjas built by the Lin Kuei. Like his counterparts, his last program command is to find and terminate the rogue inja Sub-Zero. Without a soul, Cyrax goes undetected by Shao Kahn and remains a possible threat against his occupation of Earth.

(Personal note: Made with a Big Boa head, which is a remarkably close likeness, and the Crimson Guard Immortal body, which was certainly close enough, and at least provided the necessary chest-plate. The profile was taken from the strategy guide, and presumably from the game as well.)
