is the flamboyant younger sister of Nina Williams. Their father, Richard, a former assassin, trained the two in a variety of martial arts. However, when Richard dies under mysterious circumstances, the sisters accuse each other, marking the beginning of a fierce, long-lasting feud. With both sisters going their separate ways, Anna enlists in a paramilitary organization and becomes an officer in the Tekken Force.

Anna plays a minor role in the story of the first game, only appearing as a sub-boss character for Nina. Later games, however, would begin to flesh out her story. ''Tekken 2'' saw Nina once again contracted to assassinate the tournament's sponsor, this time being Kazuya Mishima. Whether at Kazuya's behest or Anna's own choice, Anna becomes a bodyguard for Kazuya, along with Ganryu and Bruce Irvin. Soon after, Nina is captured by Mishima Zaibatsu's forces and becomes a subject of Dr. Bosconovitch's cryongenic research. Likewise, Anna is captured by Kazuya and joins her sister in a cryogenic slumber.

In ''Tekken 3'', following their subjection to cryogenic sleep in ''Tekken 2'', Nina awakes fifteen years later under the possessive influence of the recently unearthed Ogre, who compels her to target Jin Kazama for assassination. Anna awakens with her sister, though is unaffected by Ogre's influence. In an act of compassion, Anna sets out to stop Nina, who had lost her memories, from reverting to her assassin ways and to help regain her memories. However, her efforts are in vain as Nina suddenly recalls her lifelong feud with Anna, resulting in Nina leaving and severing all ties with her younger sister.

Anna is absent as a playable character in ''Tekken 4'' but makes her return in ''Tekken 5'', when the sisters' reunion triggers Nina's repressed hostility towards Anna. Anna retaliates, leading to a prolonged gunfight lasting several days. Eventually, the sisters reach a deadlock and agree to settle their grievances once and for all, with a glimpse of their battle appearing in the game's opening sequence. In the following tournament, both sisters agree that only one will emerge alive. However, despite Nina's victory over Anna, she decides to spare her life, feeling unsatisfied with the outcome.

In ''Tekken 6'''s "''Scenario Campaign''" story mode, Anna leads G Corporation's defenses against the Mishima Zaibatsu and Lars Alexandersson's rebel army; during a confrontation with the rebels, Anna's actions indirectly result in the death of Lars' friend, Tougou. She also accompanies Kazuya to Azazel's Temple in the desert. Following Kazuya's stalemate with Lars, Anna flees with him.

Anna additionally appears in Nina's 2005 spin-off action game ''Death by Degrees'' as a commander of the Tekken Force. Anna later becomes playable in ''Tekken 7'' as part of the Season 2 DLC. After the tumultuous events of ''Tekken 6'', Anna's spirit grew weary of constant conflict. After finally retiring, she meets and falls in love with an elite soldier in the G Corporation. However, tragedy strikes on the day of their planned wedding, when the sound of gunfire suddenly fills the venue amidst preparations. Anna rushes toward the commotion only to discover her beloved killed and her sister, Nina, escaping in Anna's wedding dress. Fueled by vengeance, Anna resolves to reengage in combat once more.

Anna's fighting style is based on Koppo and Hapkido, a martial art known for its use of spinning back kicks, jumping kicks and close-range throws. Although their father taught Anna and Nina the same martial arts skills, each sister has developed a distinct fighting style seen in the games. Provided by Wikipedia
