In Shaolin Monks, they have the ability to block almost all of the player's attacks, causing the player to rethink how to defeat them. The Masked Guards fight with a bladed staff-like weapon (the naginata), and use a dagger as a secondary means of assault. Also a single Masked Guard appeared in the opening of the Mortal Kombat IIand a dead Masked Guard is seen in the opening shot of the Mortal Kombat: Armageddon introduction video. John Vogel played the Masked Guards seen in the original Mortal Kombat arcade game.
In Mortal Kombat (2011) and Mortal Kombat: Shaolin Monks, Kung Lao disguises himself as a Masked Guard to gain access to the Mortal Kombat tournament. The Masked Guards can also be seen around the Courtyard.
The Masked Guards make an appearance in the first Mortal Kombat movie as ninjas loyal to the sorcerer Shang Tsung, one of which is pitted against the Elder Sub-Zero by Tsung in a pre-tournament match and is killed in the process. They also do battle with the three chosen heroes of Earthrealm, Liu Kang, Johnny Cage and Sonya Blade after they are discovered spying on Tsung, Goro, and Kano, but are defeated.
