The following is a list of video game characters featured in the Fatal Fury fighting game series developed by SNK.

Series' creator Takashi Nishiyama stated that giving the characters depth was of great importance when making the series. He noted that the first Fatal Fury featured a more polished plot and more fleshed out characters than that of his previous work, the original Street Fighter, which led to the game gaining a strong fanbase. To help market the games, certain character details were revealed in magazine promotions rather than the games themselves.^[1]

Andy Bogard (アンディー・ボガード, Andī Bogādo) is Terry Bogard's younger brother. Andy practices the Shiranui-ryū ("Shiranui style" in Japanese) Ninjutsu and a form of empty-handed ninja combat called Koppō-ken, which he trained in after witnessing his foster father's murder, in order to gain revenge on Geese Howard. Mai is the girl he grew up with who is madly in love with him and proclaimed him her fiancé. She is also the granddaughter of Hanzo Shiranui, the man Andy learned Ninjitsu from. It was after his foster father Jeff's death that Tung Fu Rue took responsibility for raising him and Terry. Andy went to Japan to train under Hanzo and grew up alongside Mai, while Terry stayed in Southtown. During Andy's time in Japan, he met the Muay Thai fighter Joe Higashi and challenged him to a match. When Andy won, he invited Joe to return to the United States with him to enter the King of Fighters tournament, held by Geese.

Late in the tournament, Andy tried to kill off Geese by himself. Geese's power proved to be too much for Andy as he almost fell to his death. Terry saved Andy, who then acknowledged Terry as the superior fighter. After Terry beat Geese at the end of their first King of Fighters Tournament, a new tournament was held, this time hosted by Krauser. Andy, while present in the tournament, did not accomplish much story-wise.

Ever since Geese's death, Andy has been busy training his young apprentice Hokutomaru in the ways of the Shiranui-style ninjitsu and Koppo-ken. Instead of fighting in the KOF: Maximum Mayhem tournament himself, Andy sends Hokutomaru in his place to see what his apprentice has learned. In Hokutomaru's ending, Andy writes him a note saying that he was proud of how strong Hokutomaru has gotten. Then he ended the note by saying he is no longer his teacher but his rival and that they will cross paths again.

When the new King of Fighters '94 tournament was announced, Andy joined Terry and Joe in the new 3-on-3 matches. Since then, Andy has always agreed to follow his brother Terry whenever he decided to enter the new version of the King of Fighters tournament. The Fatal Fury Team maintained his original formation (Terry, Andy and Joe) from King of Fighters '94 to '98. With new rules in KOF '99 allowing teams of four members, Mai Shiranui (in KOF '99) and, later, Blue Mary (KOF 2000) joined the team. After the beginning of the Ash Crimson Saga (KOF 2003, XI) Andy left the Fatal Fury team to take care of Shiranui disciple Hokutomaru, who fell sick and Mai went after him. Andy made his return to The King of Fighters XII but does not participate in a defined team. The King of Fighters XIII sees Andy rejoining the Fatal Fury team as his brother's interest in the tournament has compelled him to reunite the original Fatal Fury team from the 1994 event. In his anime incarnations, though sometimes perplexed by her actions, Andy is more open to showing his affection towards Mai.

Billy Kane (ビリー・カーン, Birī Kān) is introduced in Fatal Fury as the righthand man of Geese Howard, a crime lord in the fictitious American city of Southtown. Geese holds The King of Fighters tournament every year with Billy as his champion. Billy was the undefeated champion of the tournament, until he is defeated by Terry Bogard, who moved on to later defeat Geese.^[4] He also appears in Fatal Fury Special as a playable character for the first time.^[5] After Geese recovers, Billy appears in Real Bout Fatal Fury to assist him in the conquer of Southtown. However, Geese is ultimately killed by Terry, causing Billy to leave Southtown.^[6] He later appears in the two following games from the series Real Bout Fatal Fury Special and Real Bout Fatal Fury 2: The Newcomers which do not contain a storyline.^[7][8] In the PlayStation version from Real Bout Fatal Fury Special, Billy is brainwashed by his half-brother White in order to aid him in the conquer from Southtown. He then appears as a sub-boss character in the arcade mode, but once he is defeated, he returns to normal.^[9] A 3D fighting game version of the series, Fatal Fury: Wild Ambition was produced as well, which retells the plot of the first game.^[10] By the time of City of the Wolves, Billy has assumed control of the Howard Connection after Geese's death, though he still seeks revenge on Terry for killing Geese.

In The King of Fighters series, Billy was meant to appear in the first game from the series as a member of an England Team, composed of him, Mai Shiranui, and Big Bear, but due to several problems with the capacity of the game, and the desire from the Art of Fighting staff to add Yuri Sakazaki, Billy was removed from the game.^[11] When the new King of Fighters tournament began in The King of Fighters '95 under the control of a man named Rugal Bernstein, Billy is ordered by Geese to go in his boss' place because Geese was still healing. He joins with a ninja named Eiji Kisaragi and a mysterious man named Iori Yagami.^[12] Billy's team does not win, and at the end of the tournament Iori beats up Billy and Eiji.^[13] In The King of Fighters '97 Geese sends Billy to investigate the mysterious Orochi power in Iori. Geese hires a sadistic outlaw named Ryuji Yamazaki and tricks a good freelance agent named Blue Mary to help as well.^[14] After the tournament ends, Yamazaki demands his pay from Geese by attacking him and Billy. The same team is shown in The King of Fighters '98, The King of Fighters 2002 and Neowave but none of those contain a storyline.^[15][16][17] He also appears as an assistant character (known as "Striker") in The King of Fighters '99: Evolution and The King of Fighters 2000. In the former he is available for any character, while in the latter he is a striker for Andy Bogard.^[18][19]

In The King of Fighters 2003, Geese orders the team of Billy Kane, Ryuji Yamazaki, and Gato to infiltrate the tournament in another attempt to take over Southtown.^[20] During the spin-off game The King of Fighters Kyo Billy appears as boss character along Geese to fight against the Bogard brothers and the protagonist Kyo Kusanagi.^[21] In KOF: Maximum Impact 2, it is revealed Billy has moved to the countryside of the UK with his young sister, Lilly Kane, and has decided to return to Southtown once again, willing to show the Meira twins: Alba and Soiree the town should be embarked by no one.^[22]

Billy also appeared in the console version of The King of Fighters XIII, released in November 2011.^[23] He is also present in the otome game King of Fighters for Girls.^[24]

Billy Kane appears in the TV anime film Fatal Fury: Legend of the Hungry Wolf, where he is voiced by Daiki Nakamura in the original Japanese version and Paul Dobson in the English dubbed version. Like in the original Fatal Fury video game, Billy Kane is one of Geese Howard's underlings alongside Raiden, Ripper and Hopper. He enters the King of Fighters tournament alongside Raiden on Geese's behalf and later mortally wounds Tung Fu Rue while the Bogards and Joe are escaping from Geese's men. In the final battle of the film, he ends up fighting against Andy Bogard and ends up being defeated by him.^[25] He appears again in the sequel Fatal Fury 2: The New Battle, where he makes an unvoiced appearance in the beginning of the film, in which he is confronted by Laurence Blood at the Pao-Pao Cafe and is defeated off-screen.^[26] Billy makes an extended cameo appearance in the third film, Fatal Fury: The Motion Picture, this time voiced by Tomohiro Nishimura in the original Japanese version and once again by Paul Dobson in English. He encounters his old adversary Andy in a night club, but the two are confronted by Laocorn's henchman Hauer before they get a chance to fight again.^[27]

In the second episode of the anime spin-off mini-series The King of Fighters: Another Day, Rock Howard, Geese's son, stops Billy from killing Lien Neville who was carrying out a hit on him. Billy tries to convince Rock to help him, because as he carries Geese's heritage, Lien would try to take him out too. Instead, Rock decides to save Lien's life and fights Billy, who almost manages to kill him as well for shaming Geese's legacy, but is blown away by a beam fired over Geese Tower.^[28] He also stars in manhua from the video games which retells his actions from the games.^[29] Additionally, in the manga The King of Fighters: Kyo authored by Masato Natsumoto, Billy starts investigating Kyo Kusanagi in order to make him talk about the ancient demon Orochi.^[30]

In Gamest's 1997 Heroes Collection, Billy was voted as the staff's fourth favorite character.^[31] In the character popularity poll on Neo Geo Freak's website, he was voted as the seventeenth favorite character with a total of 757 votes.^[32] For the special endings in The King of Fighters '97, three video games journals, Gamest, Famitsu and Neo Geo Freak, had to create a team composed of three characters from the game so that they would be featured in an image after passing the arcade mode. The special team created by the Neo Geo Freak's staff was a team of fire wielders: Billy, Kyo Kusanagi, and Mai Shiranui. The special ending only appears in Japanese versions of the game.^[33]

Duck King (ダック・キング, Dakku Kingu) appears in the original Fatal Fury as one of the first four opponents in the single-player mode. Possessing incredible talent when it comes to brawling and street dancing, Duck King once challenged Terry Bogard to a street fight and lost. He trained himself in order to surpass Terry. Duck uses a unique fighting style which includes rhythmical dance-like movements and attacks. His primary special move is a flying cannonball technique.

In Fatal Fury 2, Duck was one of the characters from the original game who is defeated by Krauser in one of the game's cut scenes, although he would appear as a playable character in Fatal Fury Special. He would retain his cannonball technique, now dubbed the Head Spin Attack, along with new special moves such as the Dancing Dive, Break Storm, and the Beat Rush. He also has a new hidden special move called the Break Spiral. From Special and onward, Duck would be accompanied by his pet chick "P-chan". He makes another quick cameo in Bob Wilson's ending Fatal Fury 3 before returning as a playable character in Real Bout Fatal Fury and its sequels, Real Bout Special and Real Bout 2. He also appears as an exclusive character in the PlayStation version of Fatal Fury: Wild Ambition.

Although Duck King has made numerous cameo appearances thorough The King of Fighters series, including as an alternate Striker (a character who helps the player in battle) in The King of Fighters 2000, he did not appear as a playable character until The King of Fighters XI, where he appears as a member of the new Fatal Fury Team along with Terry and Kim Kaphwan.

Hwa Jai (ホア・ジャイ, Hoa Jai) is the first of three opponents the player faces in the original Fatal Fury before the final match against Geese Howard. A former Muay Thai champion once nicknamed "The Hero of Muay Thai" (ムエタイの英雄, Muetai no Eiyū), he once fought against Joe Higashi in the past and lost, causing him to lose his title. Seeking to defeat Joe, he became a more reckless and dangerous fighter. After being banned from competing in the Muay Thai circuit, his brutal talent was noted by Geese Howard, who hired him to serve as one of his bodyguards and a participant in the King of Fighters tournament. His special technique, the Dragon Kick, was developed to compete with Joe's Tiger Kick. He also gains additional strength by drinking a sort of Super Drink, which thrown at him by one of Geese's men when he is in danger.

In Fatal Fury 2, Hwa Jai is one of the characters from the original game who gets defeated by an unknown challenger (Wolfgang Krauser). He is apparently hospitalized and visited by Joe Higashi, as seen in Joe's ending in the game and in Fatal Fury Special. He makes further cameos in the subsequent Fatal Fury games (Fatal Fury 3, Real Bout, Real Bout Special and Real Bout 2) as Joe's training partner and trainer. Despite having been absent since his original appearance as an opponent character in Fatal Fury, Hwa Jai has been confirmed to return in The King of Fighters XIII and marks the first time the character has been playable. Kim, following his "reform" of his previous teammates (Chang Koehan and Choi Bounge), seeks out Hwa Jai and Raiden as he believes they still work under Geese Howard. It is not the case as Geese had returned to America long ago but Raiden manages to talk Hwa Jai into joining the team to bolster their reputations as fighters. Hwa Jai accepts, partially due to wanting to fight Joe once again.

Raiden (ライデン, Raiden) first appears in the original Fatal Fury as the second of the final four computer-controlled opponents in the single-player mode. He was once a popular face wrestler until he was betrayed by his tag partner during a match (a character later revealed to be Big Bombarder from the SNK wrestling game 3 Count Bout). This incident transformed him completely and he became a notorious heel wrestler. Not satisfied with venting his frustration in the ring, he enters the King of Fighters tournament as a masked fighter, acting as one of Geese's guardians. His primary special move in the game is the Vapor Breath. This character was modeled after real life pro wrestler Big Van Vader.

He returns as a regular playable character in Fatal Fury 2 and Fatal Fury Special, where he renounces his Raiden persona and now fights as an unmasked face wrestler under the identity of Big Bear (ビッグ・ベア, Biggu Bea). He trains at his native land of Australia, where his deadly strength increased on several levels. He also develops a friendly rivalry with Terry, as seen in his endings in both games.

Raiden also appears in The King of Fighters XII and the sequel. In KOF XII none of the characters are assigned into teams but for KOF XIII they are. Raiden's teammates in KOF XIII are Kim Kaphwan and Hwa Jai. Kim is mistaken in thinking Raiden and Hwa Jai are still in the employ of Geese Howard, wanting to "reform" both men. Raiden convinces Hwa Jai to act as if they are so they are able to enter the tournament to build reputation for themselves. The Fatal Fury characters refer him as "Bear", his face persona, which he denies.

This status is what enabled him to convince the authorities to give him custody over Chang Koehan and Choi Bounge to rehabilitate them out of their criminal ways.^[60] Although both men resent Kim for his actions, they later grow up to grudgingly respect him.^[61] Due to the increase of required members in The King of Fighters '99, Kim's rival, Jhun Hoon, joins the Korea Team.^[62] However, in The King of Fighters 2001, Jhun has an accident and he is replaced by Kim's student, May Lee.^[63] By The King of Fighters 2003, the requirements of members return to three and this time the members of the Korea Team are Kim, Jhun and Chang.^[64] In The King of Fighters XI, Kim appears as a member of the Fatal Fury Team along with Terry Bogard and Duck King as the team needed one more member.^[65] In The King of Fighters XII, Kim is a playable character, but like each of them, he does not have a team.^[66] As The King of Fighters XIII has returned to assigning the characters into official teams, Kim is cast as the leader of his team, composing of himself, Raiden and Hwa Jai (both from Fatal Fury: King of Fighters). He is teamed with the men because, after "rehabilitating" Chang and Choi, he seeks out Raiden and Hwa Jai believing they are still working for Geese (they are not but they pretend that they still do so they can compete in The King of Fighters tournament). The games from the series which do not contain plot, The King of Fighters '98 and The King of Fighters 2002, also feature Kim along with Choi and Chang in the Korea Team.^[67][68] In the console version of The King of Fighters Neowave, Kim appears as a hidden character without an official team.^[69]

Ultimate, he appears both as a background character in the King of Fighters Stadium stage and as a Spirit.^[77]

Kim also appears in two of the three animated films from Fatal Fury in which he takes supporting roles. He is voiced by Daiki Nakamura in the Japanese versions and by David Kaye in the English dub. In Fatal Fury 2: The New Battle, Kim challenges Terry to fight after learning that he defeated the former crime lord from Southtown Geese Howard to test his own strength.

After Terry regains his courage, he challenges Krauser again and wins the rematch, causing Krauser to commit suicide due to his loss.

B. Jenet (B・ジェニー, B Jenī), real name Jenet Behrn (ジェニー・バーン, Jenī Bān), is the leader of a group of pirates known as the Lillien Knights. Jenet entered the Maximum Mayhem to rob Kain R. Heinlein of anything valuable he might be keeping in his mansion. In her ending, she passes out amidst the destruction of Kain's mansion after defeating him. Her crew saves her from being trapped under the rubble, but fails to secure any of the treasure they had been looking for. She decides to stay in South Town for some time, leading her to participate in the new King of Fighters tournament in City of the Wolves.

In The King of Fighters Maximum Impact 2, her parents are revealed to be incredibly wealthy; she formed the Lillien Knights when she became bored of her tedious lifestyle. Before the start of the tournament, she attends a party in her otherwise occupied parents' place. While there, the son of the host attempts (and fails quite miserably) to impress her with his paltry skills in Savate. Although Jenet is rather repulsed by his arrogance and embarrassing lack of skill, she learns from him that the King of Fighters tournament is being held once again. After her Lillien Knights knock the man unconscious and rob his father, Jenet decides to join the tournament in hopes of winning the prize money. She is voiced by Rei Saitō in Japanese, and by Gina Rose in the English version of KOF: MI2.

Jenet is very comfortable around men, and her win quotes and prefight and postfight animations express that she doesn't seem very serious about fighting. In The King of Fighters XI, she was in the tournament for monetary gain strictly, and she enters with Tizoc and Gato to form the Fatal Fury/Mark of the Wolves team.

Her fighting style, the LK (Lillien Knights) arts, is similar to savate, a French form of kickboxing. Her moves are mostly made up of attacks by swooping her dress (in moves such as specials "The Hind" and "Crazy Ivan" and Super Special Move "Aurora") and she is able to control the wind (being reflected in her projectile attack "Buffrass" and her Super Special Move "Too Many Torpedoes"). Her Super Special Leader Move "An Oi Madamoiselle" sees her take off her left shoe and beat her opponent with it.

Her appearance consists of a purple dress with a skull and crossbones, red fingerless gloves, a red belt with gold lining, and blonde hair, along with stiletto heels as used in "An Oi Madamoiselle".

Marco Rodrigues (マルコ・ロドリゲス, Maruko Rodorigesu) is a Brazilian Kyokugen-style karate expert, who trained under Ryo Sakazaki. He leads a somewhat austere life in a wooded area on the outskirts of town, and fights using powerful, deliberate attacks. He enters the Maximum Mayhem tournament to help promote Kyokogenryu and lure new students to his dojo. In City of the Wolves, he is forced to train at Yuri Sakazaki's fitness club due to his dojo's sign being stolen, and enters the King of Fighters tournament to reclaim it and rebuild his dojo's reputation. Just like Ryo, he has several famous moves from Art of Fighting with some of his own derivatives.

Marco was renamed Khushnood Butt in the U.S. release of Garou: Mark of the Wolves, possibly to avoid confusion with mixed martial artist Ricco Rodriguez; the character's name would be reverted to Marco in future localizations beginning in The King of Fighters XV (2022).

Tizoc, otherwise known as Griffon Mask (グリフォンマスク, Gurifon Masuku) or the Griffon in the Japanese version, is a character from both the Fatal Fury and King of Fighters series. He started out in the Fatal Fury game Garou: Mark of the Wolves and is described as being a well-renowned and popular professional wrestler. By the time of Garou: Mark of The Wolves, Tizoc already sees himself as a washed up has-been and enters the Maximum Mayhem tournament in order to regain his passion for wrestling.

When the events of King of Fighters 2003 occur, Tizoc is an up-and-coming superstar in the professional wrestling circuit and joins the Fatal Fury team after being invited by Terry Bogard himself after his brother Andy becomes unavailable since he is teaching the young Hokutomaru in Shiranui style ninjutsu in Japan. In The King of Fighters XIV, there is a new character known as King of Dinosaurs (キング・オブ・ダイナソー, Kingu Obu Dainasō), who shares the same voice actor, a similar fighting style, build, color schemes and feather decor as Tizoc, now teamed with the former NESTS agent Angel and Ramon on Team Mexico. During the tournament, several opponents, such as Tizoc's former teammate Terry, easily address King of Dinosaurs as Tizoc despite the new fighter's denials,^[115][116] while other characters, who may or may not identify King of Dinosaurs as Tizoc, merely deem him foolish.^[117] Despite Eisuke Ogura's pre-release claims that King Of Dinosaurs is not Tizoc,^[118] the Team Mexico ending reveals that King of Dinosaurs is in fact Tizoc who suffered a humiliating defeat by Nelson. To seek revenge, Tizoc adopted a new "heel" persona, King of Dinosaurs, relying on his teammates Ángel and Ramón to help cover his former identity. In The King of Fighters XV, King of Dinosaurs and Ramón team up with former KOF XIV tournament host Antonov to form the new wrestling team named "Team G.A.W. (Galaxy Anton Wrestling)".

The characters from Fatal Fury have received major positive reaction with GamesRadar calling Terry Bogard as "one of SNK's most memorable characters", as 86th "most memorable, influential, and badass" protagonist in games.^[120] IGN praised the increase of the series' cast but heavily criticized the final boss Geese Howard for his high difficulty.^[121] Avi Krebs from GamingExcellence.com commented that Billy Kane is one of the hardest boss characters from the first Fatal Fury, but he remains "pale" in comparison to Geese.^[122] Kotaku's Patricia Hernandez wrote "one of Fatal Fury 2's biggest contributions to the medium was that it was the first game to introduce a character with breasts that moved on their own. Known as Mai Shiranui, that character is famed for having very, uh, lively breasts. Though Fatal Fury may not be a huge franchise nowadays, its legacy is very much alive: many top fighting games include a similar jiggle effect".^[123] While acknowledging that Fatal Fury fans might be disappointed by the reduced roster of fighters in Fatal Fury 3, GamePro praised the new third fighting plane and ranking system, and concluded that "instead of simply adding more fighters, FF3 does more with fewer fighters (hidden moves and so on) and a unique method of gameplay".^[124] They remarked that Bob and Franco are "uninteresting" new characters but praising and the modifications to Mai Shiranui's Swan Dive attack.^[125] The cast of Garou was praised for their animations which was compared with the ones from Marvel vs. Capcom 2.^[126]
