Bi-Han

He's malicious and has a deadly ambition for ruling Earthrealm as he himself says. He's clearly of the same mind as Shao that Liu Kang is keeping him underfoot. He wasn't evil. He had darkness due to his life as an assassin but he was willing to reform as his mk1 ending was him ditching the Lin Kuei. While essentially neutral, he was a cold-blooded, vicious assassin whose soul had become corrupted from years of violence and remorseless killing. At the end of the first Mortal Kombat tournament, Bi-Han was murdered by Scorpion in retaliation for his own death at the cryomancer's hands. Bi-Han and his brother Kuai Liang are the sons of the previous Lin Kuei Grandmaster. Both were gifted with supernatural abilities - Bi-Han becoming a Cryomancer called Sub-Zero, and Kuai Liang a pyromancer called Scorpion. They would soon gain a sworn adopted brother in Tomas Vrbada (later to be codenamed Smoke), who had been orphaned due his family accidentally trespassing onto Lin Kuei grounds. Together, the three would participate in the defense of Earthrealm as their clan had done for many centuries. However, Bi-Han's ambition to be greater than what they were would begin to consume him, so much so that when their father died, Bi-Han did nothing to help him, a fact he deliberately hid from the softer Kuai Liang.
