Lin Kuei. Like his counterparts, Cyrax's last programmed command is to find and
terminate the rogue ninja, Sub-Zero. Without a soul, Cyrax goes undetected by Shao
Kahn and remains a possible threat against his occupation of Earth.
Cyrax is captured by Sub-Zero and is reprogrammed with new orders: destroy Shao
Kahn. With the Kahn unable to detect the assassin's soulless presence, Cyrax delivers
a successful sneak attack. But, after eliminating Kahn and saving Earth, Cyrax awaits
new orders from his Lin Kuei headquarters. The orders never come and Cyrax
malfunctions. He ends up stranded in the middle of a vast desert, blindly heading
towards his base.
