Sub-Zero is one of the most popular characters in the Mortal Kombat series. 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. Kuai Liang bears a scar on his right eye which he received between the events of MKII-MK3. However - as of Deception - the scar has faded away, possibly because of the effects of his Dragon Medallion.
