cryosleep between Tekken 2 and 3, Mishima Zaibatsu, while under Heihachi's leadership attempted to use her genes to create child super soldiers that could fit the Devil Gene project for the organization army. Steve is one of the survivors thanks to the cover by the now late-Doctor Emma Kliesen. Nina stars in her own action game, Death by Degrees, released in 2005. The game provides an alternate backstory for Nina and Anna; the plot concentrating more on their father and how he died when they were children. In this game it is revealed that Richard Williams had struggled with a few guardsmen, and shouted for Nina to grab a gun which one of guardsmen had dropped. However, her hesitation and fear caused the guards to get the upper hand and shoot Richard Williams, killing him. Anna is shown comforting her sister moments after, while the older Nina looks over the scene. The rivalry which stemmed from the incident crossed over to the real-time events of the Tekken series. Nina also appears in the 2012 crossover fighting game Street Fighter X Tekken with her official tag partner, Kazuya. In the cinematic trailer, they battle against Ryu and Ken at a condemned building, before Kazuya captures Ryu as bait to lure Jin out.

And we didn't want that with Nina." Nina has a blonde ponytail, blue eyes, and a slim hourglass figure, yet a powerful build. Her look contrasts that of her younger sister, Anna, who is a brunette.

In Tekken 6, one of Nina's extra outfits is one of her Death by Degrees costumes. Her default costume
