Cyrax is a player character from the Mortal Kombat fighting game franchise created for Midway Games by Ed Boon and John Tobias. Making his debut in Mortal Kombat 3 in 1995, he is a member of the Lin Kuei clan of assassins who underwent transformation into cyborgs. Along with counterparts Sektor and Smoke, Cyrax was assigned to hunt down the rogue former clansman Sub-Zero, but unlike Sektor, he and Smoke were able to rediscover their human side, with Cyrax in particular joining Sonya Blade and Jax Briggs as a member of the Outer World Investigation Agency after having his soul restored. His backstory prior to his transformation is expanded in the 2011 Mortal Kombat reboot.
Cyrax has also been featured in other Mortal Kombat alternate media such as the 1996 animated series Mortal Kombat: Defenders of the Realm and the 2011 web series Mortal Kombat: Legacy. The character has received mostly positive reception, particularly for his Fatality finishing moves and gameplay.
