Nina Williams (ニーナ・ウィリアムズ Nīna Wiriamuzu?) is an Irish, cold-blooded assassin that made her first appearance in the original Tekken game and has appeared in every Tekken game ever since. Nina has a lethal fighting style, consisting of throws, grapples, and holds. She has a rivalry with her younger sister, Anna Williams.
During the end of Tekken 2, both Nina and Anna undergo Cryogenic Sleep. They are experimented upon for 15 years (this is the reason why they both remain physically young throughout the tournaments). While in Cryogenic sleep, her ovum was taken without her consent and used to create Steve Fox (who first appears in Tekken 4 and onwards).
Nina also starred in her own game, Death by Degrees, an action-adventure title released in 2005 for the PlayStation 2.

Nina's persona seems to be cold and indifferent. In fact, she had been drugged by an underground force when she was young in order to create the perfect assassin, regarding the chronology of Death by Degrees. The only man she had ever trusted was her father, who died shortly before Tekken 2. Ironically, after her father's death, Nina was controlled by Ogre, and was thus unable to feel any emotion.
Nina's personality remains monotonous yet sadistic when it comes to teasing Anna. Nina's win poses range from tomboyish and masculine to flirtatious, usually by placing a foot on top of the opponents body or showing off her body figure. Although she is an assassin, most of her missions are inclined for the good of the world, though she was hired to kill Steve by the syndicate during Tekken 4 and also assisted Jin when he started a world war during Tekken 6.
Nina is notable for her blonde hair and blue eyes. Her look contrasts from that of her sister, Anna, who is a brunette.
- Main article: Nina Williams/Outfits
Nina's signature color is purple, as she has at least one purple outfit per game. Her trademark costume is the "catsuit," as she has worn many different designs of catsuit in both Tekken and Death by Degrees, which are made of materials resembling spandex, PVC and leather. She wears her hair tied into a ponytail or a braid. Her skin is ivory-colored and she has an hourglass shape. Nina almost always wears lipstick, from violet (DbD) to red (TK1, TK2,TK:BV) to bronze (TK3) to peach (TTT, TK4, TK5, TK6).
In T7 however, she wears a white wedding dress. Though the reasons are rather messed up, the dress was originally Anna Williams's. Nina stole that dress on Anna's wedding day in Italy when Anna was going to marry a soldier of the G-Corporation (who apparently was from the Italian Mafia) and later Anna found out it was her sister Nina who had killed Anna's future husband. Nina ran out of the Chapel or Mansion (Location before the wedding is still unknown.) Leaving a furious Anna behind. This is the main reason why Anna calls out to Nina when they meet and fight in Tekken 7 "I'll tear you to pieces, Nina!" Due to Anna being furious with Nina stealing her wedding dress and killing her fiancé.
Version 1 A silent assassin. She learned assassination techniques from her father and of Aikido for self-protection from her mother. Therefore, she has an outstanding fighting sense. She was sent to assassinate Heihachi Mishima, the sponsor of the tournament, but her real intentions are not clear.
Version 2 Because she has learned assassin techniques and the art of Koppou from her father, and Aikido and self-defense techniques from her mother, Nina has a superior sense of combat. She's been commissioned to assassinate the tournament's sponsor, Heihachi Mishima. However, truth be told, she's been having second thoughts about harming people.
Version 3 Nina acquired her unusual combination of skills from her parents. Her father, once an assassin for the IRA, left Ireland to escape his past. His marriage to a British Aikido champion created a bloodline that would spawn a child with incredible talent and a killer instinct. Nina was kidnapped by an underground force and drugged into believing that the Rave War sponsor must be assassinated. God help anyone who gets in her way.
Ending Description, "High Heels": Anna opens a door. A few seconds later, there is a closeup of her feet. She is wearing a shoe on her right foot, but she doesn't have a shoe on her left foot. Anna points at her left foot, and then she looks at Nina like she is saying "Where have you hid my shoe?". Nina shrugs. Anna walks up to Nina and starts shouting at her. Nina gives her a disgusted look and slaps her. Anna turns around, cries, and puts her hands over her face. A few seconds later, Nina grins and holds up Anna's missing shoe, revealing that she had the shoe all along.
Version 1: A master of Aikido and Koppo techniques, she is an assassin for the people of Ireland. Although Nina's mission is to assassinate Kazuya Mishima, her personal agenda is to finally settle the long battle with her sister, Anna.
Version 2: Nina Williams is an Irish assassin who has an excellent command of Koppou and Aikido techniques. As one should expect, Nina's relationship with her estranged sister is at its worse. Knowing the evils fueling his daughters' hatred Richard Williams pled with Nina to make things right between them before his death, but she couldn't bring herself to comply with her father's last wishes. This time, at the tournament, Nina intends to bring an end to her and her sister's deadly quarrelling, brushing aside her assignment to assassinate Kazuya.
Ending Description, "Cemetery": Nina walks up to her father's grave and puts flowers on it. The camera zooms away from Nina for a second, and then the camera zooms in on Nina, meaning that someone is walking towards her. Suddenly, Nina turns around and pulls out a gun. Anna is shown being the person that was behind her. She, too, is holding flowers. After Nina stares at her for awhile, Anna shakes her head. Afterwards, Nina turns her head and looks at her father's grave, then turns her head back towards Anna's direction. Finally, Nina decides to walk away from the place. Anna proceeds to visit her father's grave, and Nina is shown smiling as the screen fades to white.
Version 1 After failing to assassinate Kazuya Mishima in the last Tournament, Nina was forced to become a test subject for cryogenic research. Reawakened by Ogre's powers, she is determined to eliminate Jin Kazama.
Version 2 In the last tournament, Nina was ordered to assassinate Kazuya, but an untimely quarrel with her sister, Anna, prevented it. Shortly thereafter, both sisters were captured by Kazuya's corps and were used as guinea pigs in Bosconovitch's Cold Sleep #2 experiment. They did not awaken for 15 years. Heihachi's private corps, the Tekken Forces, went to the burial site and excavated the God of Fighting. This unearthing unleashed its spirit, which awakened Nina's resting soul. Now controlled by the God of Fighting, Nina acts robotically, with the command to assassinate Jin Kazama.
Ending Description, "War Between Sisters": Nina is lying down in some kind of machine as work goes underway to restore her memories, much to no avail. The scene changes, and Anna and Nina walk into a
small cemetery where snow has fallen. Anna, who is holding flowers, leads Nina to a grave (which is probably the grave of Richard Williams) and places the flowers by that grave. There is a flashback (from Nina's Tekken 2 ending) and Nina begins groaning in pain. Anna goes to see what is wrong, but Nina slaps Anna in the face so hard that she falls to the ground. After yelling angrily at Anna, Nina furiously walks away, leaving Anna on the ground, smiling.
Prologue: After the King of Iron Fist Tournament 2, the Mishima Zaibatsu used Nina as an experimental test subject for cryogenics research. Fifteen years later, Nina was released from cryosleep to fight in the third tournament. She in the tournament while suffering from cryosleep-induced amnesia.
Since then, Nina escaped from the reaches of the Mishima Zaibatsu and spent her days carrying out missions as a contract assassin. To this day, she has been unable to regain memories of Anna or her previous life.
As a woman without memories or close relations, the only person Nina could count on was herself. Carrying out her hits for profit was the only reality she could rely on. Without memories or anyone to rely on, the only thing she could do was to execute her contracts for money.
After the Tournament, Nina pursued her target, Steve Fox, to his hotel in order to complete her objective.
While preparing for the hit, Nina received additional information on the target from the Syndicate...
The Syndicate's additional information revealed that Nina was in fact Steve's mother, who was created through in-vitro fertilization without Nina's knowledge. Nina is ready to assassinate Steve (via sniper rifle), but finds it very difficult for her to pull the trigger as she feels guilty of murdering her only child. Lei Wulong busts open her door, yelling "Freeze!" Nina does not adhere and fires two shots at Lei (which he dodges). She quickly escapes through the window and runs across the street to where Steve is. The two share a moment together, until it is interrupted by Lei. Lei fires two shots at Nina, but Steve protects her by knocking her over. Nina gets up and runs, thanking Steve for his help, but is still pursued by Lei as Steve watches.
Nina Williams, an assassin with no memories of her past.
The Syndicate told Nina that Steve Fox was her son, but she felt nothing.
Instead, she decided to meet her sister Anna to uncover her past, but soon Nina's memories rushed back to her.
In the end, they decide to set a rivalry in the King of Iron Fist Tournament 5.
After being inspired by their sibling battle, a movie director insists on starring them in an upcoming film.
Nina and Anna are shown fighting with swords on a castle's rooftop. In the end, Anna is victorious, and Nina falls to the ground. The director yells "Cut!," and then people congratulate and applaud Anna. Nina walks away from the scene amidst the praise. As she walks away from the castle, Nina presses a button on a remote control in her hand, and the castle set behind her explodes. Then, Nina is shown smiling.
At the King of the Iron Fist Tournament 5, Nina Williams has finally settled the score by defeating her younger sister, Anna Williams.
Shortly after her mission was complete, Jin Kazama recruited Nina to be his bodyguard and assist his Tekken Force in taking over the world. With strong tension between the Mishima Zaibatsu and G Corporation, the King of the Iron Fist Tournament 6 was announced.
In order to remove any threats to the life of Jin Kazama, Nina enters the tournament.
Ending Description: Nina is in the bathroom located at the Mishima Zaibatsu Victory Celebration party. She is applying lipstick when all of a sudden, Anna bursts in. She attempts to kick Nina, but Nina dodges, resulting in Anna breaking a mirror. A fight between them ensues, but is unseen and the force of the blows are powerful enough to shatter another mirror just outside the bathroom. Nina emerges from the bathroom afterwards and walks away, victorious and seemingly unharmed. It is then seen that she has rendered her sister semi-unconscious and childishly drew all over Anna's face with her lipstick. Nina is shown assisting Jin at his schemes. She is defeated by Lars twice. After Jin sacrificed himself to kill Azazel at the end, she told Lars that she already knew Jin's plans about the world war since the beginning; so he can awaken Azazel's physical body, but she was unsure whether Jin's actions were right or wrong. She then left with a Mishima Zaibatsu helicopter, which may or may not signify that she became Mishima Zaibatsu's temporary new CEO during Jin's disappearance.
While searching for Jin, Nina and Tekken Force are suddenly confronted by Heihachi, who has returned to reclaim the Zaibatsu. Defeated, Nina is forced to work for him and stands behind him while he announces The King of Iron Fist Tournament 7. Although she questions Heihachi's motives, Nina follows him as he travels to the Archers of Sirius to get them on his side. They infiltrate their main base and take out several exorcists before Heihachi fights and defeats Claudio Serafino.
They then continue their search for Jin, following on the rumors on something evil appearing in the Far East. But Nina later finds that Lars has taken Jin into hiding, saying that things have become more complicated. After the Tekken Force fails to capture Jin, Alisa and Lee, Nina decides to take the SWAT team and go in herself.
At Lee's medical facility, Nina launches a surprise attack and confronts Alisa in battle. While staying her ground, the Tekken Force captures Jin and holsters him away. But Lee manages to hijack the helicopter and traps Nina inside the facility. As the rebels make their escape, Nina is trapped in an explosion set off by Lee. However, she survives the attack, pondering as to why Lars and his group are sheltering Jin. Nina then decides that it will be fun to watch.
After failing to apprehend a comatose Jin Kazama from Violet Systems while under her last orders from Heihachi, Nina Williams decided it was time for her and the Mishima Zaibatsu to go their separate ways. On her first private assassination job, she was tasked with infiltrating a mafia wedding... posing as the bride. As it turns out, the wedding was actually between a G Corporation executive secretly part of the mafia, and the now-retired Anna Williams.
Before the wedding ceremony could start, Nina managed to steal Anna's wedding dress from her dressing room, and successfully infiltrated the wedding posing as the bride. Shortly afterwards, a firefight broke out where Nina took out all her targets, including Anna’s fiancé. However, the commotion had attracted the Tekken Force, who had been dispatched to suppress the violence, and they gave chase. With the Tekken Force, and possibly Anna too, in hot pursuit, Nina made her escape.
That's when she bumped into a man she found vaguely familiar. The man wouldn't leave her alone. He seemed to have something he wanted to say to her... Nina decided that a confrontation was her best chance of escape.
Ending Description: After defeating Steve, Nina is soon confronted by the Tekken Force. She throws a knife at one of the soldiers and quickly follows up with a flash grenade. Nina then escapes, leaving her unconscious son behind.
In Steve's ending, when Nina was defeated by her own son who demands to know how she is connected to him. She explains to him that her genes were used by the finance to create ultimate supersoldiers through experimenting on children, with Steve as one of them. The project failed due to most of the children dying from that experiment, but Steve survived thanks to Emma Kliesen's effort to cover up Steve's status from Zaibatsu's eye. As Steve discovers that she is his mother, Nina warns him that he will never be her son because she couldn't care less about him. When the Tekken Force suddenly arrives, Steve helps Nina escape while holding them off.
Nina Williams is featured in Tekken: The Motion Picture. In this story, she was hired and seduced by Lee Chaolan to assassinate Kazuya Mishima. She failed both times, as Kazuya managed to escape the first time and was saved by Jun Kazama the second time. During the Tournament, Nina is fighting Anna Williams, until Anna gets beaten. For awhile, it's a mystery whether or not she survived but as the island starts to explode, the other survivors can be seen, including an injured Nina.
Nina appeared as a playable character in Tekken Tag Tournament. She retains her moveset from Tekken 3 along with a few additions. While the game is non-canonical, it is still looked at as a refined version of Tekken 3. In said game, the sisters continue their rivalry.
Ending Description: Anna comes trying to end their rivalry. Nina, after listening to Anna reason, puts her hand out for a truce to their quarrel. Anna reluctantly puts out her hand just to have Nina pull her into her standing armbar. Nina gives a look and smile of reluctance at their sibling rivalry as she holds her sister in the submission.
2005's Death by Degrees marked the first Tekken spin-off stand-alone game and casts Nina in a starring role for the first time. Originally, the game was supposed to simply be entitled Nina but was changed to Death by Degrees to reflect the multi-front combat system in the game.
In the game, Nina is assigned a mission that is a joint operation between the CIA and MI6. The team that she's with consists of two "sneakers" (John Doe and Edgar Grant) and one "sweeper" (Nina). They are supposed to infiltrate the Amphitrite, a Glafeera corporation cruise ship. Then, they are supposed to execute a video recon of a meeting held by high-ranking members of a certain organization. Nina is assigned to enter the fighting tournament that is being held onboard the ship, and then she is supposed to hide herself and await further orders. Upon mission completion, they are supposed to rendezvous and make their exit.
The game provided an alternate backstory for Nina and Anna with a flashback, suggesting that their father died when they were children protecting them. Richard Williams had struggled with some guards, and shouted for Nina to pick up a gun one of them had dropped. However, her hesitation and fear caused the guards to get the upper hand and shoot Richard. Anna is shown comforting Nina moments later, while Nina looks over the scene. Presumably, Nina and Anna's rivalry stems from this event.
This rivalry crosses over to the real-time events of the game, when Nina is sent to investigate a mysterious group. At an Island prison, she fails to interrogate her target when she is knocked out by Anna, who is working on behalf of the Mishima clan with the Tekken Force as bodyguards, as she owes Heihachi for her sister's operation. At the end of the game, Anna is the final boss Nina must face.
Nina appeared in the 2010 live-action Tekken movie, she is portrayed by Candice Hilebrand.
In the movie, she and her sister are assassins working for Kazuya. The three of them also sleep together. Kazuya sends both of them to kill Jin. Their attempt gets foiled as Christie shows up. Nina later fights Christie in the tournament. During the fight, Christie tells Nina about what happened last night but she tells her that she likes Jin and that he's cute too. Christie manages to escape the joint locks of Nina and manages to knock her out after a brutal fight and Christie tells her that she does not share.
Nina appeared into the 2011 CGI film, Tekken: Blood Vengeance. She's the first character to appear in the film, riding her motorcycle on a highway. Afterwards, she's ambushed by G Corporation employee and her younger sister, Anna Williams, who has set up a decoy for her. After a family reunion, Nina easily defeats Anna in a short battle, and quickly returns back to Jin after quickly escaping from soldiers from G Corporation (Anna's backup). Upon returning to the Mishima Zaibatsu, she shows Jin old files and newspaper articles of the Mutare Experiment (the M-Cell), which was performed on Jin's old school friend, Shin Kamiya. Upon learning about this, Jin then sends Nina to Russia where she would activate Alisa Bosconovitch, who she would then send to an international school in Kyoto, Japan to act as a spy to get info about Shin.
Nina, later on, appears halfway through the film, where she informs Jin that Alisa is ignoring their orders and doing her own investigation (with Ling Xiaoyu). Realizing that G Corporation will track Alisa down, Nina turns Alisa's network offline. Afterwards, Jin sends her to Kyoto to go after Alisa. On her way to the android girl's location at Lee Chaolan's mansion, Nina receives a radio message that G Corporation soldiers led by Anna are after Alisa, too. After noticing her sister's presence, she decides to help Alisa and Xiaoyu escape by turning Alisa's network back online. After the two girls escape the mansion just in time, Nina arrives to welcome Anna once again. Later, it's revealed that there was another fight between the two sisters at the mansion. Nina falls unconscious after Anna wakes up. Anna then attempts to capture Nina, amusing Lee Chaolan. This attempt leads to an unknown outcome, though Nina most likely escaped.
Nina appeared in Street Fighter X Tekken as a playable character, her tag partner is Kazuya Mishima.
Nina appeared as a playable character in Tekken Tag Tournament 2. She retains her moveset from Tekken 6 along with a few additions and a network of alliances.
Nina appears in Tekken Revolution as a playable character.
Nina appears in Tekken Card tournament as a playable character. She plays as a balanced character who can heal rapidly, draw rapidly, and launch powerful attacks, but at the cost of having more difficult, or "technical" requirements for some cards to activate. She can be played in a lot of unique ways, and doesn't favor any major ability, except for healing. She can heal herself in large amounts, but her cards have to be in specific positions in order to work, making her healing tank playstyle a lot more luck-based. Playing as Nina requires patience, a high understanding of her cards' various technical abilities, and not being afraid to take chances, but she is overall a very useful character that any seasoned player can use. She currently is the best character to use in the game, doing well in tournaments, and is also a viable tag partner.
Nina appears as a playable character in Tekken (Mobile) as part of the main story character alongside Kazuya. Nina currently has three costumes: the camo-suit, the wedding dress, and the black catsuit.
Ever since her debut, Nina instantly became a fan favorite, due to her speed, lethal moves, and chain throws. Her strength is on par with most characters, and she can even evade and counterattack. Her combos are something to watch out for, as they are elaborate, strong, and even lethal. However, her chain throws are difficult to perform and require precision and patience (the same goes to Anna as well).
Nina's fighting styles is comprised of martial arts of Aikido & Koppojutsu in ways of an assassin.
Undoubtedly her greatest weaknest is that her juggle combos do not deal much damage, struggling to go above 60 and many of them do not even go above 50. This makes her more reliant on her chain grapples, which can go up to 70 damage.

Lars and Nina witness this and the latter tells Lars that she knew about Jin's plot and states that Lars is no saint himself. Nina then leaves on a helicopter owned by the Mishima Zaibatsu. This may or may not mean that she is the new leader of the Zaibatsu.
- In the first chapter of Story Mode in Tekken 7, it is confirmed that Nina serves as the de facto leader of the Zaibatsu in Jin's absence before Heihachi reclaims the company by force and convinces her to work for him.
- In the Scenario Campaign Mode, Nina's Player 2 outfit is all black except her undershirt is gray instead of red and white and during the scene of her and Jin about to go back to the Zaibatsu by riding their motorcycles, she wears her black biker outfit customization. She also wears this biker outfit in Tekken: Blood Vengeance during her fight with Anna in the beginning of the movie.
- She is the boss of Mishima Zaibatsu, Central Subway Line and the first half of the Mishima Zaibatsu, Central Tower.
- Nina's opponents in the "Arena" mode are Lars Alexandersson, Anna Williams, Kazuya Mishima (instead of Jin Kazama who is typically fought, as they are allies) and Azazel.
- Nina is the only female character who is "frowning" (an expression similar to Jin) in her CG art. Every other female is smiling.
- In Nina's and Anna's endings, the former wears her blue cocktail dress from Death by Degrees.
- It is possible that after joining Jin’s Mishima Zaibatsu in this game, Nina may have been given more detailed information about the experiments that were conducted on her, since she seems to know more details about Steve when she encounters him in Tekken 7 than she did in Tekken 4.
- Nina has a special win pose with Anna, where Anna poses for Nina only to get kicked when turning her back to her.
- Nina has two special win poses with Jin. They pass each other with Nina smiling and waving in a flirtatious, playful way.
- In another, Nina steps aside when Jin acknowledges her and then watches him intently while passing by.
- Nina is portrayed by Summer Daniels in the "Girl Power" trailer.
- She appears alongside other female assassin characters in Anna's ending, where Anna is seen defeating them all.
- Some of the lines in her pre-fight and win animations are taken from her conversation with Jin in the Scenario Campaign mode in Tekken 6 and later with Lars in the Scenario Campaign ending.
- In the Rage and Sorrow trailer, and later in the story mode, Nina's outfit is her black biker outfit from the movie, Tekken: Blood Vengeance.
- Nina is voiced by Mary Elizabeth McGlynn. She later reprises her role in Tekken 6 and onwards.
- Nina's bosses are Bryce Adams (Nina has to fight Bryce two times), Enrique Ortega (two times), Lana Lei (three times) and Anna Williams (two times). However, if we put them in the exact order of how Nina fights them, it will be - Bryce Adams, Bryce Adams, Lana Lei, Enrique Ortega, Anna Williams, Enrique Ortega, Lana Lei, Lana Lei and Anna Williams. If player completes Anna mode, the player can fight Heihachi Mishima as the final boss.
- Several kicking animations used in this game would later become moves for Nina from Tekken 5 onwards; Sweeper Combo, Deadly Assault and Deadly Hunter.
- Nina is the final boss of Lars and Alisa's Tekken Pachislot 4 storyline. She is defeated by Lars, Alisa, and Lee and surrenders information to them about Heihachi Mishima.
- The said given name was possibly meant as an acronym. But, her name was also meant as a Babylonian goddess of the watery deep, daughter of Ea or an "anglicised" form for the spelling of "Niña", meant as "girl" in Spanish.

- ^ Nina's country of origin is listed as Ireland with an Irish flag, designating that she is from the Republic of Ireland, not Northern Ireland which is part of the UK. Furthermore, her country of origin would be listed as Northern Ireland or UK if that was what was intended (see https://tk7.tekken.com/fighters/nina ). It is also mentioned that their father worked for the IRA, a paramilitary organization fighting on behalf of Republic of Ireland.
