Akira Yuki (結城 晶, Yūki Akira) is the mascot of the Virtua Fighter video game series. His fighting style is Bajiquan,^[2] a Chinese martial art (pronounced "Hakkyoku-Ken" in Japanese). Canonically, he won the second World Fighting Tournament (Virtua Fighter 2).^[3] Akira strives for perfection and will drive himself relentlessly to master his techniques. He seeks worthy opponents to fight in order to find flaws in his skills to further attain mastery. In the original Virtua Fighter, Akira serves as the assistant instructor at Yuki Budokan, and is known to be hot-blooded and impulsive by nature. He also can be naive and intemperate. After completing his training under his grandfather's tutelage at the age of 23, he went on a quest to test his abilities. When he got word of the 1st World Fighting Tournament, he decided to enter and test his abilities. He was a childhood friend of Aoi Umenokoji.

In the Virtua Fighter anime, Akira starts his quest to see the eight stars in heaven after he had gotten overconfident in his Bajiquan skills from his days training with his grandfather. He is often seen as a comedic glutton in the anime series, as opposed to the games where he is serious and disciplined. Akira Yuki and Jacky Bryant are partners in Sonic & Sega All-Stars Racing. He is appears in Project X Zone with Pai Chan as his partner, and returns in the sequel with Kage-Maru as his partner. He also appears as a guest character in Dead or Alive 5. He appears in Dengeki Bunko: Fighting Climax as a boss, as well as a playable fighter, with Pai as his assist, and was originally a non-playable final boss character in previous console release of arcade version, then eventually becoming a regular character in Ignition update. A Mii Fighter costume based on Akira's original polygonal Virtua Fighter appearance appears in Super Smash Bros. for Nintendo 3DS and Wii U as downloadable content alongside a Jacky Mii Fighter costume.

Pai Chan (パイ・チェン, Pai Chen) debuted in the first Virtua Fighter. She is the daughter of Lau Chan, another character in the game. Pai Chan was born May 17, 1975 in Hong Kong. She is a martial arts action movie star in her hometown, and her fighting style is Mizongyi (pronounced "Ensei-Ken" in Japanese). It is revealed that her favourite hobby is dancing. Pai is a leading star in Hong Kong action films. Her moods change as quickly as a cat's – she can erupt in passion in one minute, and turn icy cold in the next. Pai is Lau's only daughter, who specially trained her in martial arts from a young age. In the original Virtua Fighter, however, while Lau obsessively strove on with his training, Pai's mother worked so hard to support the family that she died of overwork. Her death devastated Pai and she blamed it on Lau; she swore that one day she would beat him. Two years later, she had become successful in the movie industry. After failing to defeat her father several times, Pai eventually learns that Lau has become ill and seeks to find a successor to his school of martial arts. Pai's goal to avenge her mother shifts and she becomes determined to defeat her father in order to gain his acknowledgment as a worthy successor and his daughter.

She also appears in Project X Zone alongside Akira as a pair unit, and returned in the sequel as a solo unit, with Kage-Maru replacing her as Akira's partner. Along with Akira Yuki and Sarah Bryant, Pai Chan makes a guest appearance in Dead or Alive 5. She appears in Dengeki Bunko: Fighting Climax as Akira's assist, and was originally a non-playable final boss character in the arcade version.

A quiet man who loves nature, he has his gentle side. He is filled with fighting spirit, however, and once provoked he is not satisfied until he finishes the job at hand. Being the strongest, he was an instant star in the pro wrestling area, and successfully defended his title several times. Dissatisfied with the level of competition, however, he turned in his belt and retired from the ring. Hearing of the World tournament, he entered to seek worthy opponents. After the end of the second tournament, Wolf had a recurring nightmare about the world being in danger. This dream was the sole reason for him joining the third tournament (Virtua Fighter 3). However, since he was defeated in the third tournament, he decided to ignore the dream and went back home. Back there, Wolf entered in countless underground tournaments and dominated. However, the same dream still haunts him.

Wolf appeared in All Japan Pro Wrestling Featuring Virtua (arcade and Sega Saturn 1997) and All Japan Pro Wrestling 2 Giant Gram (arcade and Sega Dreamcast 1999). Professional wrestler Jim Steele wrestled as "Wolf Hawkfield" in All Japan Pro Wrestling from 1997 to 2000.

IGN listed Wolf as the 4th best fake wrestler in video games,^[10] while GamesRadar ranked him as the 2nd best video game wrestler, stating "Beyond his skills and masterfully tailored ring attire, Wolf is one of gaming's most important wrestlers because of his comical self seriousness."^[11]

However, with the boat completed, Jeffry finds out that the "Satan Shark" has mysteriously disappeared. Unable to find the "Satan Shark", Jeffry starts asking the other fishermen the whereabouts of the "Satan Shark". He was then told the location of where the "Satan Shark" was seen last. However, even though he now had the location of the "Satan Shark"'s new hunting ground, he was still unable to find the "Satan Shark".

Aoi was first seen by the public as part of a teaser campaign for Virtua Fighter 3.

Taka-Arashi

Voiced by: Kiyoyuki Yanada

Taka-Arashi (鷹嵐, Takaarashi) is a sumo wrestler from Japan. His first appearance was in Virtua Fighter 3, and his fighting technique is sumo. He wears a kesho mawashi as a sign that he is a high-ranked sumo wrestler.^[16] Yu Suzuki expressed doubt that AM2 would be able to include Taka-Arashi in Virtua Fighter 3 because his mass created difficulties with his jumping moves,^[17] and he was not shown to the public until the Tokyo Toy Show in June 1996.^[16] Taka-Arashi's mass continued to present challenges, and he did not appear in subsequent installments of the Virtua Fighter series because his large size was deemed too difficult to simulate at the time.^[18] He bears the distinction of being the only character in the series ever to be retired, at least for a few games. In the Sumo world, Taka-Arashi is famous for his unusually brutal version of the fighting style. One day, while entertaining at an American bar, Taka-Arashi agreed to settle an argument in an underground fist fight. Taka-Arashi fiercely bested his opponent, a man famous in the world of underground fighting. Upon his return to Japan, Taka-Arashi informed his boss of his decision to leave Sumo wrestling. On that same day, Taka-Arashi received an invitation to the 3rd World Fighting Tournament, and, with blood still boiling with the thrill of battle, decided to enter.

Voiced by: Anri Shiono

One day, she happened to see a martial arts demonstration by Pai Chan and was amazed and captivated by the beauty and strength of her movements.

Siba

Siba (シバ, Shiba) (also known as Majid Abdul (マジド・アブドゥル, Majido Abudo~uru)) is a prototype character from the earlier builds of the original Virtua Fighter who was removed prior to the game's release, and was replaced by eventual series mascot Akira Yuki. A portrait of his appeared alongside portraits of the remaining original Virtua Fighter cast on the arcade game's cabinets, though his name was mislabeled as "Akira". He is a Middle-Eastern fighter wearing a white and purple keffiyeh, a white shirt, a purple sash; green Arabian-style pants; and red sandals.^[20] According to early beta screenshots and magazines, he was originally called "Siba", but had his name changed to "Majid Abdul" sometime during development before being scrapped altogether.

Siba is accessible through the Multiple Arcade Machine Emulator version of Virtua Fighter only via manually inserted cheat codes as a result of several data miners' discovery of unused character files hidden in the game's code.^[21] According to his profile in the character selection screen, he is a bouncer hailing from Saudi Arabia. Additionally, his name is misspelt as "Majido Ab Dul".^[22]

Despite never officially appearing as a playable character in the Virtua Fighter series, Siba would become playable in Fighters Megamix as a secret character who is unlocked after completing the "Bosses" course.

Jeff

Jeffery Buckman (ジェフリーバックマン, Jefurī Bakkuman) is another unused characters from the original Virtua Fighter. Like Siba, his data remains in the arcade version, and he is also accessible through cheat codes.^[21]

Jeff is a military character who wears camo gear, a hat, and shades, of which the latter two can be knocked off in a fight. While playable, his moveset is unfinished, as he uses a handful of Jacky's techniques and lacks throws.

His full name, Jeffery Buckman, is a likely tribute to actual VF1 design staff member Jeffrey Buchanan.^[23] The name Jeffery (minus an e) would eventually be shifted to Jeffry McWild.
