OVA
Description
Anna Williams is a central figure in the OVA *Tekken: The Motion Picture*. Her life is defined by a bitter rivalry with her older sister, Nina Williams, stemming from their childhood in an assassin family. Their father, Richard Williams, an IRA assassin, trained both daughters in the killing arts but favored Nina, fostering Anna's jealousy and resentment. This animosity deepened after their father died shielding them from gunfire, with each sister blaming the other for his death, cementing their lifelong enmity.

Within the OVA's story, Lee Chaolan, Heihachi Mishima's adopted son, recruits Anna. Lee hires both sisters for a mission to assassinate Kazuya Mishima, Heihachi's biological son, whose bloodline threatens Lee's position in the Mishima empire. While Lee maintains a strictly professional relationship with Nina, he becomes romantically involved with Anna, engaging in intimate liaisons.

Anna's actions extend beyond the contract. Driven by her deep-seated hatred for Nina, she actively attempts to assassinate her sister alongside the primary target, Kazuya. This leads to a direct confrontation between the sisters on Mishima Island. During their fight, Anna deliberately provokes Nina by invoking their father's death and revealing the truth about Lee's affections, taunting her sister with the knowledge of Lee's romantic involvement with Anna.

The conflict escalates when Lee initiates his 'R Experiment,' unleashing genetically engineered dinosaur clones across the island. Despite warnings that Anna and Nina remain present, Lee proceeds, considering them additional test subjects. A camouflaged dinosaur creature ambushes and kills Anna amidst the chaos. Nina escapes the encounter, leaving Anna to her fate.

Anna's characterization contrasts with Nina's, emphasizing her overtly seductive and provocative demeanor. She utilizes her charm and sexuality as tools, particularly evident in her relationship with Lee. Her motivations remain rooted in her bitter rivalry with Nina and her desire for validation, ultimately leading to her demise within the film's events.
