Sub-Zero is a mysterious blue-clad ninja from the Mortal Kombat video games and other media. He is an assassin for the Lin Kuei, an order of Chinese ninja that utilize mystic powers and weapons in battle. As his name implies, Sub-Zero's power is cryomancy, giving him the ability to freeze his opponents solid with icy blasts. In most MK media, Sub-Zero has a long-standing rivalry with the ninja spectre Scorpion, though their history and enmity is all but ignored in the Mortal Kombat movie.

Mortal Kombat movie

In Paul W. S. Anderson's Mortal Kombat film, Sub-Zero is portrayed by François Petit. His game history isn't explained at all in the film and he appears to work for Shang Tsung along with Scorpion. When he first appears in the film, he demonstrates his power to the chosen Earthrealm warriors by freezing Sonya Blade's handgun and breaking it. He shows off his power again in a demonstration to all the tournament contestants by freezing one of Shang Tsung's guards with an ice blast, who then falls to the floor and shatters.

Later in the film, Sub-Zero battles against Liu Kang. He attempts to freeze Liu by filling the room with an expanding aura of cold, but Liu Kang spots a bucket of water nearby and throws it into the force field. The water freezes into an icicle and impales Sub-Zero, pinning him to a wall and freezing him solid.

Mortal Kombat: Annihilation

While Sub-Zero did indeed perish during the first film, the sequel reveals that he has a younger brother who adopted his codename after the elder brother's death. The younger Sub-Zero (portrayed by Keith Cooke) is being hunted by his own clan for abandoning them prior to the Outworld invasion of Earth. He harbours no ill will toward Liu Kang and even helps him and Kitana fight off an Outworld extermination squad. After Kitana is abducted by Scorpion, Sub-Zero disappears into the shadows and is never seen again.
