Sub Zero

Sub Zero is central character appearing in the Mortal Kombat franchise, being a half human, half cyromancer (an extinct race of humanoids with the ability to manipulate ice) assassin and a regular combatant in the titular fighting tournament Mortal Kombat.

Original Timeline
Originally called Kuai Liang, the child who later became Sub Zero was kidnapped, along with his brother Bi Han, at a young age and were brainwashed to forever serve the Lin Kuei. Liang was codenamed Tundra as Bi Han was titled Sub Zero, and the two half cryomancers mastered their powers and became ice-wielding martial artists. After Bi Han was killed in the Mortal Kombat tournament by the vengeance seeking hellspawn Scorpion, Liang adopted his brother's codename and vowed to avenge his death.

Personality and Traits
Liang is depicted as a brooding yet honorable fighter loyal to the Lin Kuei. He even accepted to be transformed into a cyborg in the alternate timeline as long as they gave him time to kill Scorpion, however he later strayed from the clan after realizing how evil they were. Even after being turned into an emotionless robot, his benevolence and hunt for justice managed to wipe out the merciless personality installed in him. He was also the counterpart of Batman in the non-canon crossover game Mortal Kombat vs. DC Universe.

Weapons and Abilities
Sub Zero was trained in intense martial arts and was able to defeat almost unstoppable combatants such as Scorpion, Cyrax, Reptile, and Noob Saibot singlehandedly. As aforementioned, he is a cyromancer, and after years of practice with the Lin Kuei, he was able to master his ice-bending skills and use it in combat. This allowed him to freeze others solid in a statue of ice, shoot ice-balls from his palms, spawn kori blades (a sword made of durable ice) and slide around by freezing his soles.

As Cyber-Sub Zero, he could spawn ice bombs, a larger kori blade, teleport even more efficiently, coat himself in a shield of indestructible ice, and wield electronic shurikens.
