Although Cyrax claimed to be human again in his Gold ending, he is still clearly mechanical as demonstrated by his abilities in Deadly Alliance, although this could be merely a figure of speech referring to regaining his humanity. His face had several implants on the eye and chin (which were removed in Mortal Kombat: Deadly Alliance). In Mortal Kombat Gold, it was revealed that the cyborgs wore helmets and retained their faces underneath Cyrax's alternate outfit and ending revealed this. This was about as complex as the cyborgs were at the time. The rest of the body is filled with odd mechanical parts and wires. The skeleton is almost completely mechanical, aside from the rib cage and skull. In Mortal Kombat 3, a damaged cyborg sparks, and its skeleton is revealed. It has never been clear as to how mechanical the automations truly are. Yet when his armor is appropriated by Reptile, it is essentially a green version of Cyber Sub-Zero.
He regained his soul almost right after automation when he engaged Kabal in kombat, and helped the Earthrealm Warriors. In this timeline, Smoke was saved, and Sub-Zero was turned into a cyborg against his will instead.
Afterwards, Smoke was found by Noob Saibot and reactivated, along with some tampering of his machinery. Hopelessly imprisoned, he chose to shut himself down. Although Sub-Zero was eventually able to help him rediscover his humanity and restore him to the side of good, he was later captured in Outworld by Shao Kahn's army. The two fled Sub-Zero escaped, but Smoke was captured and forced to become a cyborg. After returning from a mission, he and Sub-Zero learned of the Lin Kuei's plans to transform their members into robots. Smoke (unit LK-7T2): Was the third and only member of the clan to be forcefully transformed into a cyborg against his will.In gratitude, Cyrax joined the Special Forces. He was then found by Sonya Blade and Jax Briggs, and was partially returned to his human state. However, Cyrax was captured by Sub-Zero, reprogrammed, and permanently malfunctioned. Cyrax (unit LK-4D4): Was the second Lin Kuei warrior who was turned into a cyborg.Sektor was devoid of a soul, lost all human emotions, and has never succeeded in his mission. The Lin Kuei programmed the cyborgs to do their bidding, and Sektor's main objective was to seek out and kill Sub-Zero, who left the clan after refusing to be transformed into a machine. Sektor (unit LK-9T9): Was the first to undergo the process of automation through the Cyber Initiative program, where he would prove to be their biggest success.
