~ Cyrax's main quote.
We're not machines, Sektor. I chose to serve the Lin Kuei, but I will not surrender my free will!
~ Cyrax

Cyrax is a Lin Kuei warrior transformed into a cyborg and an antagonists from the Mortal Kombat series of fighting games.



Cyrax as a human before becoming a cyborg.

Making his debut in Mortal Kombat 3, Cyrax was one of the four cybernetic ninjas created by the Lin Kuei, in an effort to convert all members into unfeeling, cold-hearted, cybernetic assassins to improve their performance. He was assigned to hunt down the renegade, former Lin Kuei member Sub-Zero as designated unit LK-4D4. Of the four cyborgs, he has become the second to recover his humanity. This is due to the efforts made by Sonya Blade and Jax Briggs.

He has currently allied with them as a token of his appreciation. In the alternate timeline of MK 2011, however, he was automated and dutifully serves the Lin Kuei. Cyber Sub-Zero reclaims his humanity instead of Cyrax. In the comic prequel of MKX, Cyrax and most of other living cybernized Lin Kuei are freed from Sektor's control by a now full-fleshed and revived Sub-Zero via stolen USB virus given from Kung Jin, and help Sub-Zero kill Sektor for good. As the cybernized Lin Kuei warriors bows to Cyrax as their new master due to being one of the master programmer besides Sektor however, Cyrax felt that Lin Kuei needs their human's touch from their flesh and heart back, thus entrusting Sub-Zero to led it without Cyrax, as Cyrax sacrifice his life to destroy every traces of the cybernized Lin Kuei including himself by activating the self-destruct sequence on the cybernized Lin Kuei's lair.

Mortal Kombat: Annihilation

Cyrax briefly appears in Mortal Kombat: Annihilation. The storyline involving his connection to the Lin Kuei was eschewed in favour of him being sent by Shao Kahn, the emperor of Outworld, to kill Sonya Blade and Jax Briggs. After entering the research facility which Jax was being held, Cyrax engages Jax in battle whilst Sonya deals with the extermination squad accompanying Cyrax. Cyrax's body self-destructs after Sonya incinerates him with a variation of her "Kiss of Death" Fatality.

In the film, he displays the ability to shoot tiny, spike-studded grenades and a corrosive, green plasma net - seemingly capable of rapidly and completely disintegrating organic matter, but is successfully and harmlessly blocked by Jax's cybernetic arms. His abilities as a ruthless martial arts fighting machine are shown, as he dominates Jax for almost the entirety of their confrontation. His name is not mentioned; he is just referred to as "a robot" by Sonya in a later part of the film. During the end credits, however, he is identified as Cyrax.

Powers and Abilities

As a cybernetic ninja, Cyrax is well-equipped, both in martial arts involving ninjutsu and weaponry. Cyrax houses a number of weapons in his chest cavity designed for both incapacitating and destroying targets. Of the three cyborg ninjas, Cyrax is most associated with bombardment, his arsenal full of timed explosives with a seemingly unlimited supply. He also has access to an 'energy net' capable of incapacitating his targets completely. When his soul was returned to him, not only did Cyrax retain some of his cybernetic parts, he was also outfitted with state-of-the-art technology, courtesy of the Outworld Investigation Agency.

Cyrax was now equipped with a portable device that would allow him to freely traverse across the realms without the need of stationary portals. In addition, his armor is heat-resistant, as he was able to completely submerge himself in molten rock without severely damaging himself in the process. His net weapon was replaced with a buzzsaw-like appendage, used for mid-range combat. Cyrax is also able to relocate himself across short distances by separating all of his limbs and head as his torso would transport to a different area where all of the discarded limbs would rejoin.




  • Cyrax, Cyber Sub-Zero, and Sektor are the only playable cyborgs in Mortal Kombat (2011). "Infantry" cyborgs are seen as non-playable opponents in several Challenge Tower levels.
  • Despite being the shortest of the cyborg ninjas, he is the heaviest.
  • The Mortal Kombat: Annihilation version of Cyrax has no back story and acts as a minor villain.
  • In Mortal Kombat: Legacy, it shows that the story might be going towards his Mortal Kombat 3 version, where he gets his emotions and fights for good. The evidence that supports this is: Cyrax coming back to consciousness during the process of removing his emotions, his rebellious behavior toward's the Cyborg Initiative, and, during his battle with Hydro, an announcer was heard saying "Project Cyrax offline.", suggesting that some human qualities might have returned.
  • Cyrax's original name was "Mustard".
