Sub-Zero, also known as Kuai Liang and formerly known as Tundra and possibly because of the effects of his Dragon Medallion. There are in fact two incarnations of Sub-Zero, and they are siblings: the older brother Bi-Han, and younger brother Kuai Liang. Both are blue garbed warriors that are members of the Lin Kuei that descended from Cryomancers: an Outworld race possessing the ability to generate and control the powers of ice, although both of them were born in Earthrealm.
