Nina also stars in her own action/strategy game, Death by Degrees.
During those years of Cryogenic sleep, she was pregnant and gave birth to Steve Fox (who has appeared in Tekken 4 and Tekken 5). They are experimented upon for 15 years (that is the reason why Nina and her sister both remain so young during the many years of the tournaments). During the end of Tekken 2, Nina and Anna undergo Cryogenic Sleep.
She has a rivalry with her younger sister, who is named Anna Williams. Nina has a lethal fighting style, consisting of throws, grapples, and holds. She is the cold-blooded assassin that made her first appearance in the original Tekken game, Tekken, and has appeared in every Tekken ever since. Nina Williams is a character from the Tekken games.
