sub-zero
Sub-Zero is a character in the Mortal Kombat series. A ninja of the Chinese Lin Kuei, Sub-Zero has command over the element of ice, and has the ability to freeze his foes solid.
Two people have taken the mantle of Sub-Zero. The first, Bi-Han, was killed by Scorpion in the first Mortal Kombat tournament before eventually becoming the ninja specter Noob Saibot. The second Sub-Zero, Kuai Liang, is Bi-Han's younger brother, and has helped the heroes of Earthrealm on numerous occasions, even when that meant fighting his own clan.
