Bi-Han was the original Sub-Zero, one of the most powerful and devout warriors of the Lin Kuei clan. While essentially neutral, he was a cold-blooded, vicious assassin whose soul had become corrupted from years of violence and remorseless killing. Bi-Han was shown to have a pretty deep voice. It helps that he's a Lin Kuei. In Mythologies and his Mirror Matches with Kuai Liang, Bi-Han speaks in a low, raspier voice that helps to emphasize his cold and harsh personality.
