Shadow Priests

Shadow Priests can be found in the Tower and Portal stages in Mortal Kombat II (when it was released, this "character" was called Cloak by fans), the Soul Chamber in Mortal Kombat 3, the Portal stage in Mortal Kombat: Shaolin Monks and Mortal Kombat: Deception, the Evil Tower stage in Mortal Kombat: Armageddon, and the Soul Chamber in Mortal Kombat (2011).

History of the Shadow Priests
The Shadow Priests are Shao Kahn's top and royal sorcerers, led by Shang Tsung. They were used in the plot to reincarnate Queen Sindel for the invasion plan of Mortal Kombat 3, and possibly helped with the creation of Mileena. They appear as enemies in the Outworld levels of Shaolin Monks, in which they also operate the device that restores Shang Tsung's youth. Shadow Priests guard the portals linking to various locations in Outworld and attack trespassers with various magic spells while supporting nearby comrades with magical enhancements such as strength and vitality augmentation. Shadow Priests are two of the only enemies in the game immune to Fatalities and the only ones immune to grabs.

Movie appearance
The Shadow Priests also made an appearance throughout the first Mortal Kombat film as shown approaching down the stairs above Sonya Blade who is being held prisoner by the shapeshifting sorcerer Shang Tsung in the Black Tower within Outworld.

TV appearance
In the TV series Mortal Kombat: Conquest, the Shadow Priests appear as invincible magical bodies and are among the few to remain loyal to Shao Kahn. They are expert martial artists as well as powerful mages skilled in magic. While shown as superior to all mortals, they failed to stand against Raiden. Unlike in the games, they are far more powerful than Shang Tsung.
