An assassin of the Lin Kuei clan, Kuai Liang commands the power of ice and cold. Unlike other members of his clan, he and his older brother, Bi-Han, were abducted as children by the Lin Kuei and trained in the techniques of assassination throughout their lives. Though his codename is Tundra, he has now assumed the mantle of Sub-Zero to honor his brother after Bi-Han's mysterious death. With the help of his fellow Lin Kuei Smoke, Sub-Zero tirelessly hunts the one who killed his brother.

After the victory over Shao Kahn, Sub-Zero learned from Raiden the truth:
that the Lin Kuei were ultimately responsible for the deaths of both Sub-Zero's and Scorpion's families.
Enraged, Sub-Zero offered Scorpion a chance to share in his quest for vengeance.
With the might of fire and ice combined, they were a storm of vengeful fury as they cut down their foes. Once justice had been done...
... Sub-Zero and Scorpion disappeared into legend, emerging from obscurity only to avenge the innocent. The forces of darkness will never stop this Deadly Alliance
