In the first two timelines, he is the more sinister and ambitious counterpart of Kuai Liang, his younger brother. He was killed by Scorpion in the first Mortal Kombat tournament, his brother inheriting his title, before eventually becoming the ninja specter Noob Saibot. As such, depictions of Sub-Zero from the original Mortal Kombat, Classic Sub-Zero from Ultimate Mortal Kombat 3, his associated outfit in Mortal Kombat 9, and all depictions of Noob are Bi-Han. In the third timeline meanwhile, he survives and remains Sub-Zero, becoming Lin Kuei Grandmaster, with his brother being Scorpion instead.
