the cryosleep, she suffered heavy amnesia, a fate from which her sister Anna was spared. She was also controlled by the recently awakened Ogre, the God of Fighting who sent her to participate in The King of Iron Fist Tournament 3 to assassinate Jin Kazama, - Heihachi Mishima's grandson. Near the end of the tournament, Jin managed to beat Nina back to her senses, allowing her to break free from Ogre's control. As an act of compassion, Anna wanted to end Nina's job of an assassin, however wanted to continue their rivalry. So Anna worked intensively with Dr. Boskonovitch to bring her sister's memories back. However, the project failed when Nina recovered the memory about the fact that she and her sister did not get along. After this, Nina left and did not contact Anna for some time. Nina soon revived her role as an assassin, the only other memory that she recalled from her previous life. Two years later, she was contracted by a Mafia syndicate to kill a famous British boxer, Steve Fox. However, she discovered that Steve was in fact her biological son, who was born through in vitro fertilisation during her years in cryosleep. With her genes, Doctor Abel conducted a Hybrid Gene experiment creating children, including Steve, until the experiment was cancelled after most of children died during that experiment, except for Steve and one of the surviving children, whose statuses were covered by the former Zaibatsu, now G Corporation researcher, Emma Kliesen, (Leo's mother) from being watched by the Zaibatsu's eyes. At the last moment when she tried to pull the trigger to her rifle, she somehow and rarely regained her human emotions, and refused to kill Fox. Nina abandoned her assassination attempt after detective Lei Wulong brought down the syndicate. After the collapse of her employers, Nina no longer possessed a viable reason to pursue her target. It was also revealed that she remained emotionally impassive about the discovery of her biological son, but the fact that she did not kill him when the chance presented itself shows otherwise for some. Nina decided that it was time that she re-discovered her lost memories and came to the conclusion that the only person who could help her was her sister, Anna Williams. Anna met with Nina soon after. However, Nina's memories and hatred instinctively returned, and they rapidly engaged in a brawling duel. The
