Cyrax/Original Timeline

Biographies

 * Mortal Kombat 3: "Cyrax is unit LK-4D4, the second of three prototype cybernetic ninjas built by the Lin Kuei. Like his counterparts, his last program is to find and terminate the rouge ninja Sub-Zero. Without a soul, Cyrax goes undetected by Shao Kahn and remains a possible threat against his occupation of Earth."


 * Mortal Kombat Gold: "Cyrax is finally rescued from his desert prison by the Lin Kuei. The physical damage sustained while in the desert was relatively easy to repair, but Cyrax seems very different from when he first set out on his original assassination mission against Sub-Zero. Only time will tell how well Cyrax has overcome his ordeal."


 * Deadly Alliance: "The cyborg ninja Cyrax had regained his soul with the aid of Special Forces agents Sonya Blade and Jackson Briggs. In return for their help, he joined the Special Forces Outerworld Investigation Agency and became a scout in the realm of Outworld. On his last transport to that realm, Cyrax was ambushed by a reptilian creature. His arm console was damaged in the struggle and with it his inter-realm portal technology. He defeated the creature, but will have to find some other means to return to Earthrealm. A vampire named Nitara offered Cyrax a deal to return him to Earthrealm if he retrieved for her an object from the molten depths of Outworld. His cybernetic exterior was resistant to the harsh environment in which the object was hidden, but only for a short period of time. It was a risky proposition, but it was one that Cyrax was willing to take to return to Earth. Although he did not fully trust Nitara, he agreed to travel with her to the location of the mysterious object."

Mortal Kombat 3
In Mortal Kombat 3, Cyrax was working for the Lin Kuei. He appeared alongside his partners Sektor and Smoke on the order to track down and kill a renegade member of the Lin Kuei clan, the younger Sub-Zero. This Sub-Zero had disagreed with the decision to convert all its members into cyborgs and left the clan. He was thus marked for death by the grandmasters.

During the invasion of Earthrealm by Shao Kahn and his minions, Sub-Zero defeated Cyrax and reprogrammed him with orders to destroy Shao Kahn. However, Kahn was defeated by the other Earthrealm warriors before Cyrax had a chance to do so. As a result of his reprogramming, he awaited new orders. When these never came, he malfunctioned and wandered until becoming mired in the middle of a vast desert.

Mortal Kombat Gold
Cyrax was recovered and repaired by the Lin Kuei. However, he appeared somehow different than when first constructed. The short-handed clan again sent Cyrax into battle with his fellow cyborg Sektor assigned to monitor him.

After the defeat of the fallen Elder God Shinnok, it became apparent that Cyrax had begun to experience flashbacks of his former life. Special Forces agents Sonya Blade and Jax Briggs brought him to the Outerworld Investigation Agency (OIA) headquarters and used its technology to restore his humanity. Grateful for their help, Cyrax joined the OIA as a scout in the realm of Outworld.

Mortal Kombat: Deadly Alliance

During the events of Mortal Kombat: Deadly Alliance, Cyrax was ambushed by the two Oni Moloch and Drahmin. After driving the two demons off, he became stranded in Outworld. His arm console, which allowed him to return to Earthrealm, was damaged in a surprise attack by Reptile, orchestrated by the vampire Nitara. He managed to drive off Reptile as well, with his Slice and Dice buzzsaw attack. A short time later, he encountered Nitara. She offered to help him return home, in exchange for his aid in recovering a lost artifact. They traveled to the underground chamber of a hollow volcano that housed the egg of the long-forgotten Dragon King. There, Cyrax submerged himself in the lake of molten lava and discovered the orb that would separate her homeworld from Outworld. With it now in her possession, she honored her promise to Cyrax. She used her mystical necklace to open a portal, and sent him back to Earthrealm.

Mortal Kombat: Armageddon
In Cyrax's Armageddon ending, he defeats Blaze and is filled with elemental power that shatters his robot form and makes him human once again. Siding with Sub-Zero, he defeats Sektor and Smoke. Sektor and Smoke are reprogrammed by the Lin Kuei and are held until they too regain their human forms.
