Nina Williams is the cold-blooded assassin you've been fighting since the original Tekken, and she's basically the poster child for the series—one of only four characters to show up in every single game, and the only woman who can claim that streak. Fans often note her complicated, intense dynamic with her younger sister Anna, which oscillates between genuine affection and outright hostility.
Both sisters grew up in Ireland under their father Richard Williams, who raised them on martial arts from an early age. The competitive tension between them was real; they were constantly vying for their dad's approval. Nina ended up specializing in assassination techniques, blending Aikido with bone-breaking methods—a practical skill set that made her rise to infamy as a world-class assassin pretty much inevitable.
Her entry into the King of Iron Fist Tournament came through work: she was hired to take out Heihachi Mishima, which is how she got pulled into the series' larger conflict.
