List of Baki the Grappler characters

The manga series Baki the Grappler and its sequels feature a large cast of fictional characters created by Keisuke Itagaki. It follows teenager Baki Hanma as he trains and tests his fighting skills against a variety of different opponents in deadly, no rules hand-to-hand combat. His goal is to eventually defeat his ruthless father Yujiro Hanma, who is touted as "the strongest creature on earth" and whom he despises. Many of the characters are fighters trained in various forms of martial arts with skills that reach superhuman levels.

Main characters

Baki Hanma (範馬 刃牙, Hanma Baki)

Voiced by: Masami Kikuchi (anime), Kappei Yamaguchi (OVA), Nobunaga Shimazaki (ONA) (Japanese); Robert McCollum (anime), Troy Baker (ONA; Netflix Dub), Blake Jackson (ONA; Sentai Filmworks Dub) (English)

Baki has been training in martial arts since the age of three, and has trained under various teachers and coaches throughout his life. At the age of thirteen, he decided to take his training into his own hands and left the coaches to perform more intense training in the footsteps of his father, Yujiro Hanma. He later meets with his father and becomes disillusioned as to his father's true character, and afterwards, aims to defeat and kill him. Baki first fought in the no-rules arena run by Mitsunari Tokugawa at fifteen, and went on to become its champion without losing once. Including techniques from many different martial arts, he does not adhere to any specific style. Fighting once a month, Baki thoroughly studies his opponent leading up to their match. He eventually develops the ogre/demon face on his back when fighting his brother, Jack, but manages to suppress it. Unlike Yujiro, Baki chooses to control his killing intent and fight his battles fair and honorably no matter what the outcome. Baki has encounters with all the escaped convicts in the second manga series. He is then faced with a new foe from the prehistoric era, Pickle the caveman, after Retsu and Katsumi are defeated by him. The outcome of the match between Baki and Pickle could be considered to have gone either way: Pickle was the one who was left standing after the fight with Baki, but inadvertently used a "weapon", in the form of a martial arts technique, to beat him. As stated by the onlookers a "weapon" is a tool used by the "weak" against the "strong", which would make Baki the true winner of the fight for having cornered Pickle. Subsequently, Baki's wish to have dinner with his father like a normal family is granted. Yujiro Hanma goes to his house and eats the dinner prepared by his son, dispensing never before seen knowledge with class and proper mannerisms. As thanks for preparing the meal, Yujiro invites Baki to a dinner "in his own style" at Tokyo's best restaurant. At one point during the dinner Baki asks Yujiro why he had to kill his mother; Yujiro refuses to explain his motives "to a resentful brat" and Baki grows confrontational. This triggers their final conflict, and the final part of the manga. The gruesome fight that ensues leaves Baki a broken mess despite using remarkable techniques that earn him the praise of his father. However, Yujiro recognizes Baki's unique fighting spirit and acknowledges that he can no longer be so selfish as to call himself the strongest creature on Earth. To thank Baki he starts using imaginary cooking to prepare Miso soup. Baki plays along but says the soup is a little salty, which angers Yujiro, but when he "tastes" it himself he discovers that the miso was, in fact, salty. Baki claims the moral victory due to being able to get his father involved in his own fantasy. The conflict ends in a tie, both fighters recognizing each other's greatness. In the fourth manga, he is still seen participating in arena fights and engaging in regular intensive training, but has become bored with his day-to-day life.

Yuujiro Hanma (範馬 勇次郎, Hanma Yūjiro)

Voiced by: Kenji Nomura (anime), Akio Ōtsuka (ONA) (Japanese); Matthew Tompkins (anime); Kirk Thornton (ONA) (English)

Nicknamed "Ogre" (オーガ, Ōga) and often called "the strongest creature on earth" (地上最強の生物, Chijō Saikyō no Seibutsu), Yujiro is the father of Baki and Jack. A genius fighter, he is known to have mastered all styles of unarmed combat. His repertoire apparently includes all of the well-known fighting styles like karate, taekwondo, boxing, judo, ju-jitsu and wrestling, as well as some more esoteric ones such as the secret udondi style, passed onto only the eldest sons of the Ryukyu Kingdom royal family. He has been fighting on the battlefields, using only his bare hands, since the age of sixteen, when he fought against both American and Vietcong forces in the Vietnam War. Since then, it appears that he has obtained respect from the American forces even going so far as having them recognize him as his own national power, with each U.S. president swearing friendship to him. He is sadistic and referred to as a monster, even by Baki, who claims he can not go a day without hurting someone. When Yujiro flexes his back muscles, it appears to take the shape of a demon or ogre's face, increasing his strength and combat abilities. It is said that when he started fighting for pleasure rather than survival, the image of the demon's face appeared on his back. His many physical displays of sheer strength include: stopping an earthquake with a punch to the ground, being struck by lightning with no effect on health, ripping a wooden table into two and then those two pieces together into quarters, cutting a glass table in half only using his finger as if it were a diamond, drinking a whole bottle of high grade Brandy in one gulp with no intoxication. Since his fight with Baki went viral, Yujiro is annoyed to find that he has gained unwanted fans and public attention, and has referenced several young children asking for his autograph since the fight.

Practicing martial arts for 50 years, he is one of the few people in the world able to stand toe-to-toe with Yujiro. Doppo has two scars on his face from when Yujiro jumped him ten years earlier. In their proper fight that takes place in the underground arena, Yujiro gouges Doppo's right eye out and kills him by stopping his heart. However, Doppo is revived by Kureha Shinogi. In the underground tournament, Doppo fights Richard Phyllis in round 1 and Amanai Ryu in round 2 before facing another master, Goki Shibukawa, in round 3, which he loses after a brutal match. After that loss, he decides to close down his dojo and start his training all over again. He eventually fights the escaped American convict Dorian in the second manga series. Dorian manages to cut off Doppo's hand with a strange wire-cutting technique in which he uses a wire blade projected from a lighter. Doppo later avenges this loss when he, Katsumi, and Retsu track Dorian down. Shortly after this however, Dorian escapes from the hospital and uses an explosive that is implanted into his hand to blow off part of Doppo's face. Doppo later returns to have a battle with Mohammad Alai Jr. Doppo is the star of the spinoff manga Baki Gaiden: Kenjin.

Three years ago, he left Doppo's dojo and worked for the yakuza, honing his skills in fights against guns and knives. After both watching Baki, Doppo shows Katou the underground arena. Katou's attitude is best described as arrogant, but usually being the butt of a joke; especially around Doppo, Katsumi, Tokugawa, and Baki. However, it is shown that he truly admires and cares for Doppo. Katou's first opponent in the tournament is injured by Yasha-zaru Jr. before the match, so he tries to fight the ape, but is also beaten and drops out due to injury. Katou shows up in the second manga series and fights against the convict Dorian in his secret underground hiding place.

Voiced by: Naomi Kusumi (anime), Naoki Tatsuta (OVA) (Japanese); Matthew Yang King (English)

Tokugawa is an old man of very small stature who runs the underground arena beneath the Tokyo Dome, where fighters of any style compete in hand-to-hand combat with no rules. While not a fighter himself, he is very knowledgeable not only about martial arts, but about the fighters as well, such as their birthdays and family members. Tokugawa has the final say in each and every one of the battles that take place in his arena. While he usually prefers to keep every fight in order, he will sometimes bend the rules if it means amplifying the fight in some way, even going so far as to threaten one of his own doctors with a knife when they tried to stop a fight. In order to find the strongest alive, he decides to hold the underground tournament in arena. Tokugawa is close personal friends with Doppo and Antonio Igari, as well as acquaintances (though not exactly friendly) with Yujiro. He is one of the few people to ever outsmart Yujiro. When Yujiro attempted to upset the balance of his tournament, he had his snipers, who he had secretly stationed around the arena, to shoot him with enough tranquilizer to put down a blue whale. This gives him the very rare achievement of being the only person who has ever knocked Yujiro unconscious.

Kureha is also a surgical genius able to do surgical wonders, such as restarting a heart barehanded without piercing the skin, but uses humans as test subjects.

When his father died he was adopted by his uncle who saw great potential in him. His grip is so strong that if he grabs an opponent's arm he can cause it to explode from restricting the blood flow. As the strongest yakuza in Japan, Hanayama was hired at fifteen by Hitoshi Kuriyagawa to fight a thirteen-year-old Baki, which he states he lost. Four years later he participates in the underground tournament, beating his first opponent, Bunnoshin Inagi, by breaking both his arms and backbone with one punch.

Although Hanayama won the battle, he wears a facemask for most of the series. Later on, he is shown surgically treated. His code of honor is great as he chooses not to fall in battle even if it means his death; a family vow which has been held in a long tradition passed from generations.

He faces Bunnoshin Inagi in round 1, before losing to Orochi Katsumi in round 2. He is looked upon as an older brother figure to Baki.

He also has a friendly sparring match with Biscuit Oliva and another match with Mohammad Alai Jr. When not fighting, he's quite eccentric (as well as a bit senile) as he lives the day and fears nothing. Although in the series Gouki is said to be a master of the old style of jujutsu, and when he fights Doppo it is said that he represents Jujitsu, most Gouki's techniques looks like aikido, and even Goki himself resembles the aikido master Gozo Shioda, founder of the Yoshinkan aikido.

Voiced by: Ako Mayama

Doppo's wife and Katsumi's adoptive mother. She is very timid and, like Kozue, she always fears for her loved ones' safety. Unlike Kozue, however, she supports Doppo's violent lifestyle and always cheers for him calling him her Superman, it is unknown if she ever directly knew that Doppo had been killed by Yujiro or whether it was just that part of her knew something was terribly wrong. She appears frequently throughout the series, showing up to watch Doppo fight in the tournament vs The Bouncer and Yu Amanai (during this match Doppo completely ignored Amanai's opening monologue and yelled into the stands proclaiming his love for Natsuki and that he was going to win it for her). She was thought to be killed by Dorian during the escaped convict story but in fact, he left her unharmed. Later in Baki Son Of Ogre when Katsumi prepares to face off against Pickle, she appears before him saying she had contacted Katsumi's real mother to wish him luck before the fight, Katsumi embraced his adoptive mother thanking her for raising him and always supporting him at which point Natsuki bursts into tears of confusion saying she wasn't his real mother, in his head Katsumi says to himself he doesn't care what she says and that she has always been the best mother anyone could want being supportive and loving.

Dr. John (ジョン博士)

Voiced by: Yosikazu Nagano

He was a doctor who tried to create a serum that could exponentially increase human strength. However, no one wanted to test it. The idea came from a chance encounter with Yujiro, whom he saw kill a polar bear with his bare hands. He developed a serum and then found Jack Hammer saying he was perhaps the hardest working but weakest fighter in the world given Jack's frail physique at the time, however due to Jack's immense tolerance for pain the Doctor thought Jack would be the only test subject that could withstand the transformation the super steroid provides, after Jack takes the drugs Buren monitors Jacks training and abilities with Jack reaching higher and higher peaks of athletic performance, sprinting great distances within 10 seconds, lifting near literal tons of weight with one arm and obliterating the best sparring partners that any fighting gym could offer. The serum proved to bequite successful in increasing his strength, but he took too much and it turned him into a ruthless monster of a fighter. Dr. Buren's idea was good and his intentions pure, but Jack took things way too far. In the anime, Buren is last seen typing a document of his sighting of Yujiro and his experience with Jack. Once finished, he shoots himself in the head.

Diane Neil (ジェーン)

Voiced by: Yurika Hino

The mother of Jack Hanma. She posed as "Jane" and acted as if she was attracted to Yujiro's fighting skills and traveled with him during the Vietnam War. It was part of a ploy to capture and kill him. When it is later revealed that her real name was actually Diane Neil and that she was working for the United Nations, Yujiro raped her. She reappears very briefly at the end of Grappler Baki.

Tournament fighters

Mount Toba (マウント斗羽)

Voiced by: Yū Shimaka (Japanese); Christopher R. Sabat (English)

A veteran giant professional wrestler known all over the world. When fellow wrestler and Baki's upcoming opponent, Junichi Hanada, causes a locker-room incident, Toba badly beats him for disrespect and takes his place against Baki. It looks as if he is about to defeat Baki, but after 30 years of wrestling, Toba's right leg gives out. Baki lets Toba lose with honor by smashing his leg so he can not stand. He later fights in the underground tournament as a replacement when Yasha-zaru Jr. injures two fighters. Toba goes up against Retsu and loses by submission via kneebar. Like Antonio Igari he also fights dirty going as far as to kick sand into Retsu's eyes as well as throw his cape over Retsu to bind him like a net. He later provides commentary for Igari's matches in the tournament. He is one of the stars of the Grappler Baki Gaiden manga, where he has a wrestling match with Antonio Igari. He dies after the match, with a grand funeral held in his honor after his death. His appearance and name are based on the Japanese professional wrestler Giant Baba.

Kanji Igari (猪狩 完至, Igari Kanji)

Voiced by: Toru Okawa (anime), Kiyoyuki Yanada (ONA) (Japanese); Brice Armstrong (anime), DC Douglas (ONA) (English)

An old pro wrestler known all over the world by his ring name "Antonio Igari" (アントニオ猪狩). In the tournament, he fights and defeats American kickboxer Rob Robinson in the third fight, and Kin Ryuzan in the second round before losing to Baki in the third. Before the 3rd match, he realizes he could lose and goes so far to kneel and cry, begging Baki to let him win but this is simply one of his means of psychological warfare to make Baki underestimate him. He is well known for fighting dirty going as far to kick Baki in the balls, as well as pretend to give up so he could sneak attack Baki and even going so far as to hire an actress who looked enough like Baki's mother Emi Akezawa to try to psych Baki out further. He is one of the stars of the Grappler Baki Gaiden manga, where he has a wrestling match with Mount Toba. In the second manga series, Anton is defeated two times and left for dead by Sikorsky who scars his face badly in the shape of a star. However he survives and reappears in helping transport Sikorsky to the Korakuen arena. At the end, he witnesses the shadow boxing fight that Baki visualizes against Yujiro. His appearance and name are based on the Japanese professional wrestler Antonio Inoki.

Andreas Regan (アンドレアス・リーガン)

Voiced by: Shinya Hashimoto

A professional wrestler of immense size, he is 2.4 meters tall and weighs over 310 kilos. He is easily the biggest man in the tournament, second only to Andre Andov Garrand, and makes Mount Toba look small. Andreas easily loses to Baki in the first match of the tournament. Baki convinces him to use all of his might which surprises him because no one has ever asked him to use all his power.

Zulu (ズール)

Voiced by: Takuo Kawamura

More of a beast than a man, he is a buff fighter from Brazil that uses Vale Tudo. He beats Muay Thai kickboxer Dentoranee Jitpika in the second match, before losing to Baki.

Kinryuuzan (金竜山)

Voiced by: Takuo Kawamura (Japanese); Kyle Hebert (English)

A current yokozuna in sumo. He beats Izo Motobe in the fourth match of the tournament, before accidentally breaking his arm and shoulder in the fight with Igari Kanji in round 2 which resulted in his father/trainer throwing in the towel. It is revealed that the Yokuzuna had tried to stop himself from falling on Igari and crushing him thus the reason he broke his own arm from it being completely straight upon impact with the ground. Kinryuuzan's trainer explains that the position that Igari had put the Yokozuna in prior to his arm breaking would have resulted in a loss had the fight been a sumo wrestle. Afterwards he rips off his top knot as a sign of disgrace only to be congratulated by Igari for a good fight and convinces him to never stop fighting. Later, he almost has his back broken by Yujiro.

Sergei Taktarov (セルゲイ・タクタロフ)

A sambo fighter from Russia. Sergei breaks Regan's arm before his match with Retsu as a show of strength. He is easily beaten by Retsu in the fifth match when his neck is broken. He is brutally beaten again, but this time by Andre Andov Garrand because he failed Russia.

Bunnoshin Inagi (稲城 文之信, Inagi Bunnoshin)

Voiced by: Takuo Kawamura.

A Nippon Kempo fighter, who Inagi Kaoru Hanayama in the first round. Before the match begins, he taunts Hanayama by offering him a face guard, which Hanayama promptly crushes and rolls into a ball.

He passes out from the back pain while trying to put Hanayama in a submission.

Roland Gustaf (ローランド･グスタフ)

Voiced by: Eiji Yanagisawa (teenager), Akeno Watanabe (child)

A catch wrestler who is beaten by Orochi Katsumi in round 1. He lost despite managing to dislocate two of Katsumi's joints. He is fairly well known as Doppo knew quite a bit about him. He is trained by Billy Riley, who happened to be a real-life legendary trainer of catch wrestlers in Great Britain. He later fights and is choked out by Yujiro.

Mouko Ri (李 猛虎)

Voiced by: Yoshikazu Nagano

The only taekwondo user in the tournament he fights Ian McGregor in round 1. He nearly wins but is knocked out in one punch by the boxer. He later fights and is knocked out in one axe kick by Yujiro.

Ian McGregor (イアン・マクレガー)

Voiced by: Mitsuru Ogata

Ian is the heavyweight boxing champ. He knocks out Li Mouko in the first round and fights Shiba Chiharu in the second round. The spirit of Ian's stepfather's father (Ian's stepfather is also his boxing trainer) appears to him in order to give him inspiration to continue fighting against the very tough Shiba Chiharu. He is clearly based on John Lawrence Sullivan because he describes himself as a bare-knuckle boxing champion with only one loss on his record, and he has a very similar appearance to Sullivan. In the fight against Shiba one of Ian's hands are broken and his trainer throws in the towel in order to protect his boxing career. Despite this, Ian chooses to keep fighting, but he eventually breaks both hands, causing his trainer to run into the arena and restrain him. As a result, his decision is overruled and he loses. He is later knocked out by Yujiro with an uppercut. Baki encounters Ian inside the Arizona Prison. Ian had been trying to become the strongest convict - a dream he gives up on. Before he is released he's beaten by Mouth, only to be rescued by Guevara. He may have been based on Mike Tyson. In the English dub, his name is changed to Olam McGregor (perhaps to avoid confusion with the actor Ewan McGregor). During the credits of the second to last episode, he is seen on a flight back home sitting across from Regan.

Chiharu Shiba (柴 千春, Shiba Chiharu)

Voiced by: Tomohiro Nishimura

Leader of the Kurenai racing gangs, he is a street fighter that doesn't seem to feel pain. He fights Hatanaka Kouhei in round 1 where he severely breaks his own arm as a form of intimidation before viciously beating Kouhei. In round 2 he fights Ian McGregor with shadow bonding and nearly defeats the boxer. Shiba wins by breaking both of McGregors hands with his rock hard skull. Though he wins he is unable to continue due to injury. He is replaced by Andre who proceeds to throw him through the ceiling after a disgruntled Shiba confronts him and demands to know why he's being replaced by Andre in the tournament. After recovering from that, he is struck in the throat by Jack Hammer and knocked out. He's last shown (still injured), riding with his gang. Shiba makes a surprise return in the Son of Ogre series. At the request of Hanayama Kaoru, Shiba is to be Baki's training partner for the upcoming fight with Yujiro. Kaoru says Shiba must be Baki's partner because Shiba is weak. Baki is reluctant to fight Shiba at first, but finds a reason of his own when Shiba keeps on attacking him at various times throughout the day.

Kouhei Hatanaka (畑中 公平, Hatanaka Kōhei)

Voiced by: Daisuke Hirakawa

A judo practitioner who breaks Chiharu's left arm before being beaten senseless by Chiharu. He later fights Yujiro who destroys him again by using his own style of judo against him and throwing into the ground.

Kengo Misaki (三崎 健吾, Misaki Kengo)

Voiced by: Jin Yamanoi

A shorinji kempo user who beats Mike Queen in round 1 with an armlock, before having his wrist and ankle bitten into by Jack Hammer and getting knocked out in round 2.

Richard Filth (リチャード・フィルス)

Voiced by: Masayuki Nakata

He's a bouncer from America. Though his style could be described as brawling, he more less just stands there and takes punishment. Though this works with 3 men armed with baseball bats this does not work with Doppo. He wears a tuxedo to the ring and Doppo complied by wearing a nice suit of his own. He later fights and loses to Yujiro after breaking his hand punching Yujiro in the head, and a groin kick that makes him fly away. In the English dub his name is changed to Phyllis, perhaps not to label Americans as filth.

Roger Harlon (ロジャー・ハーロン)

A grappler and Olympic wrestler who loses to Gouki Shibukawa in round 1. He is also one of the many people Yujiro beats on his rampage by giving him a powerful belly to belly suplex. Harlon is shown to be a big fan of Andre Anov Garland.

Amanai Yuu (天内 悠)

Voiced by: Masaya Takatsuka

Yujiro's apprentice. Yujiro met him in America, where he was serving as a bodyguard to the US president. Yujiro took him under his wing after he kidnapped the president. His style is based on love in contrast to Yujiro's style which is more aggressive and based on rage. He fights Yamamoto Minoru in the first round, before losing to Doppo. After the fight he begged Tokugawa to end his match for Doppo's safety, and Yujiro nearly kills him and calls him weak.

Andreanov Garland (アンドレアノフ・ガーランド)

Voiced by: Eiji Yanagisawa

A giant Greco-Roman wrestler who has over 6000 wins and no losses. He replaces the injured Chiharu and is beaten by Jack Hammer who almost bites off his hand leaving it dangling by a piece of skin and stabs his ribs into his heart. He is later nearly killed by the Russian convict Sikorsky. He requested himself to be chained with specialized titanium shackles because he could not control his strength, but vowed to unlock himself if "Mother Russia" was in danger; thus given the nickname by his peers, "The Chained Patriot", what is most remarkable about him is that he does not possess any formal training apart from the basic rules of any combat sport he competes in and relies heavily on his own natural strength, which enabled him to cut down a tree with a single swing of his axe, rip the full roots of it from the ground and dig not any mere hole but a near meteor sized crater. In the English dub his name is pronounced "Zeigan/Zargan". This character is based on the real life Russian wrestler Alexander Karelin.

Baki characters

Dorian (ドリアン)

Voiced by: Unshō Ishizuka (OVA), Banjō Ginga (ONA) (Japanese); Aaron LaPlante (English)

An American convict that escaped from Algardos prison after being hanged. In his youth, he was a Private in the United States Army shortly after World War II, and he was stationed in Japan where he presumably started learning martial arts. He became a practitioner of Chinese kenpo and learned from the same school, and reached the same rank of Sea King as Retsu, the first Western man in history to attain that title. Besides Chinese Kempo, he also knows a form of hypnosis to cloud his opponents' senses and allows Dorian to defeat them. He has memorable battles with Doppo Orochi and Katou where he nearly killed them. After being beaten by Doppo he is hospitalized where he escaped and goes to Doppo's house where he attacks him and blows part of Doppo's face off using a bomb located on his wrist. He is later defeated by Retsu and is mentally incapacitated, making him harmless. He is later seen, under the protection of Oliva, at the Chinese Tournament where he loses in the first match. He is briefly seen in the anime during the Maximum Tournament storyline, making a cameo as both the man who dug a cave overnight and the man who recommended Retsu for his title. Of all the five convicts, he is most notable for his use of a wide variety of tools in fights, such as flammable materials, lightweight wire, and even covering his knuckles in broken glass.

Hector Doyle (ヘクター・ドイル)

Voiced by: Wataru Hatano (OVA), Takehito Koyasu (ONA) (Japanese); Johnny Yong Bosch (English)

A British convict who escaped after surviving his execution on the electric chair. While not clearly stated, he was probably a soldier in the British Armed Forces since in Britain the death penalty only exists for treason and military law, and he had a soldier acquaintance who helped his escape to Japan. He attacked and severely injured Rob Robinson and later scares Baki at school, although they don't actually fight. He has fought with Biscuit Oliva, Shinogi, Orochi Katsumi, Retsu and later Doppo after Doyle used explosives to detonate the floor of the Shinshinkai dojo. After being stabbed in the eye by Retsu, he later befriends Katsumi and plans on escaping the country on a ship. Yanagi comes and nearly kills Doyle and blinds him before Doyle escapes. Doyle is later seen in a cave where Oliva finds and captures him. His fate remains unknown. He fights using metal blades implanted into his joints and controlled by his nervous system. He also has a generator where his heart is which boosts his strength. As a side note, he is presumed to be Scottish since he referred Ardbeg Scotch as being "a drink from my home country" during his conversation with Retsu.

Sikorsky (シコルスキー)

Voiced by: Daisuke Ono (OVA), Kenjiro Tsuda (ONA) (Japanese); Grant George (English)

A Russian convict who escaped from Evans prison in Russia. To do this he had to climb up the smooth surface of a missile silo since the prison was converted from an old ICBM base. After escaping, he nearly killed Andre Andov Garland. He fights with Baki, Oliva, and Jack Hammer and even teams up with Yanagi to try to defeat Baki. He is defeated by Gaia in the Maximum Tournament arena. Gaia uses his environmental battle method to beat up and terrorize Sikorsky, and forces him to surrender and admit his defeat. His fate afterward is unknown. Although it does not say if Sikorsky has a particular martial art, it seems he uses just strength and has extremely powerful fingers, capable of carving into his opponent's flesh with his raised knuckles.

Spec (スペック)

Voiced by: Atsushi Imaruoka (OVA), Chafurin (ONA) (Japanese); Kyle Hebert (English)

Spec is an American convict who escaped from a Florida state prison, located 200 feet underwater in a giant submarine. Spec kills the councilor, who came to see him in prison, before escaping and killing five more guards on the shore. After wanting to fight Baki he is arrested. Instead of yielding to the law, he decides to make the Japanese detention center his second home. Spec has quite possibly the bloodiest battle in the series with Hanayama Kaoru where they both inflict severe injuries on each other. He threw bullets into Hanayama's mouth and forced his jaw shut, setting them off and blowing two large holes in his face. Spec has his throat ripped out after their second fight, which ultimately kills him. He knows a technique called "The Apnea Rush" where he throws a hundred rapid punches, without breathing, that destroys an opponent by melting their bones. Spec used it to heavily damage the Statue of Liberty which was almost destroyed. After his defeat, he aged rapidly and it is found out he is actually 97 years old. This character is based on the real life serial killer Andrei Chikatilo and Richard Speck.

Ryuukou Yanagi (柳 龍光)

Voiced by: Hisao Egawa (OVA), Issei Futamata (ONA) (Japanese); Chris Edgerly (English)

Japanese convict who escapes from being enclosed in rocket-proof special glass. The smallest of the convicts physically, he is later being shown as the most deadly. He is the only convict whose crime is known, that he killed a dozen men in prison as a test bed for his new skill. He uses a special martial art called Way of the Void. In this style, he practices Vacuum Palm, Whip of Mercury, Poison Hand and many others. He is seen to be an old acquaintance of Shibukawa Gouki. He has fought with Shibukawa, Baki, Doyle and Izo Motobe. He is responsible for poisoning Baki with his Poison Hand technique and also for nearly killing Doyle and for destroying Shibukawa's eye preceding the storyline. He fights with Izo who uses kenjutsu to stab his leg and cut off his Poison Hand. Yujiro then comes and declared Yanagi the loser which Yanagi did not accept. As Yujiro was ready to leave he quickly spins and smashes Yanagi's face with a backhand, nearly killing him, and leaving the left side of his face disfigured. Yanagi's defeat ended the Escaped Convicts saga.

Morio Sonoda (園田 盛男)

Voiced by: John Eric Bentley (English)

The Japanese inspector in charge of the escaped convicts. After the failure of the special forces of police, he hires Oliva to finish the job. He respects the grapplers fighting the convicts, since they do a better job than the police. However, he doesn't understand how powerful the fighters actually are.

Michael Holes (マイケル・ホールズ)

Warden of The Arizona Prison. He arranged a fight between Ian McGregor and "The Mouth", to ensure that Ian could not restart his boxing career.

Biscuit "Unchained" Oliva (ビスケット・オリバ)

Voiced by: Yusaku Yara (OVA), Hochu Otsuka (ONA) (Japanese); James C. Mathis III (English)

An assassin working for the US government as well as being a special jailer in the Arizona State Prison. He possesses an iron body and is almost invulnerable to anything. He and Yujiro crossed paths while he was sent to assassinate a drug cartel leader. At the same time, he ran into Yujiro. He refers to Yujiro as "Mr. Ogre" and tends to be polite and eccentric before fighting. Yujiro mentions to him that he should take time with his kills rather than being quick about it. Oly understands Yujiro's bloodlust but prefers to do his job than play around. His trademark is his punch which can go through his opponent's heart. Is brought in by the US government to track down and capture the escaped convicts in the Search For Our Strongest Hero manga series. He has just defeated "Che Guevara" in the Arizona Prison and was recently defeated by Baki Hanma in a brute force showdown. He doesn't seem to practice any form of martial arts, instead using his freakish strength and resilience to overcome threats. His various feats of strength and muscle control seen in the manga are doing an exercise in which he repeatedly pulls a Chinook helicopter towards the ground, withstanding multiple shotgun blasts and then squeezing out the shot by flexing, breaking through iron doors with ease in the Arizona prison (in one case by turning a locked handle until the metal twists and ruptures around it), and flinging the convict Hector Doyle by one ankle into the floor with such force that the entire building they are in shakes. He also has one bizarre technique in which he curls into a perfect sphere of muscle in which he is impervious to attacks, but can uncurl and seize his opponents, 'eating' them "like Pac-Man". He then crushes them with his muscles. He uses this on Baki, but fails the second time he tries to use it. He is then beaten unconscious, if briefly, by Baki when they abandon the use of techniques and simply pound each other with all their might without dodging or blocking. His appearance and name are based on former Mr. Universe and three-time Mr. Olympia Sergio Oliva.

Jeff Markson (ジェフ・マークソン)

A former NYPD cop, who used to threaten and extort from hippies, as a "secret side job". As a result of his corruption, Oliva was sent to hunt him down. Markson encountered Oliva while he was doing his usual side job, and Oliva destroyed every part of his body, "barely within a limit of not killing a human" according to Markson, leaving him in a hideously disfigured shape. Since then, Markson lived only thinking of avenging Oliva. 24 years later, he attacked and took control of a business building after setting a bomb, taking two dozen hostages. He demanded Oliva to face him in exchange of the life of the hostages, to which Oliva happily complied. He welcomed Oliva with several blasts of shotgun, but the bullet was stopped by Oliva's muscle. Markson then drew out a Japanese sword and attacked him, but again it had no effect on him. Oliva, disappointed by Markson's powerless attack, gave a punch into Markson's chest. The punch crushed his heart, killing him instantly and the force of the punch blasted Markson's body out of the building's window.

Master Kunimatsu (マスター国松)

Ryuukou Yanagi's sensei. He appears to be about Tokugawa's age, being very thin and old. His left arm is missing and he later divulges to Tokugawa that he had his left arm removed to prevent Yanagi from killing him with his poison hand technique. Yanagi keeps his teacher's rotten arm on display. Kunimatsu's dojo roster features students from across the globe, but none from Japan (Yanagi being the one exception).

Mohammad Alai (マホメド・アライ)

A legendary boxer who dedicated his life in fighting for the weak, and developing a perfect art of fighting. When he was still young, he encountered a young Yujirô with whom he had a fight, to see how his art of fighting is developed. Yujirô gained the upper hand, and the two legends have since kept a friendly relationship. He became catatonic after his son defeated him soundly, 5 years before the events of Baki. However, he finally retrieves his punch and starts training again, explaining his reason for doing so during an interview. He saved the life of his son during his fight with Baki, by punching him before he killed Alai Jr. He left his son crying after his defeat.

Mohammad Alai Jr. (マホメド・アライJr.)

The son of the famous boxer Mohammad Alai. He possesses some of the fastest reflexes and has destructive power in his punches. He participated in the Chinese tournament alongside the Japanese/American team. During the tournament he showcased his amazing abilities as a fighter. He claims to have perfected a martial art that only involves punches. After the tournament he challenged Baki's friends to provoke Baki himself. He easily defeated Gouki in match (Gouki didn't take it as a life or death fight) and slightly struggled against Doppo Orochi (he wasn't taking Alai seriously, and Alai dominated in their match), but is then beaten senseless by Jack Hammer who never really shows mercy in any fights unlike Doppo and Gouki. He is then seriously injured and totally defeated by Doppo and Gouki in fights in which they do not hold back against Alai Jr. Despite this, he still challenges Baki to a fight in the Korakuen Underground arena, believing that his strength and style is better. However he has one major weakness: unlike every other fighter who has faced Baki, he was not prepared to face the possibility of his own death in the fight, which goes back to his losses against Gouki and Doppo in the second matches he had against them. He loses to Baki without landing a single hit, and Baki almost kills him before Alai Sr. jumps into the ring and stops him.

Kaiou Ryuu (劉 海王, Ryū Kaiō)

Voiced by: Mitsuru Ogata (OVA), Shozo Iizuka (ONA) (Japanese)

An aged warrior, though not as old as Kaku. Ryu challenged his students to reach the Sea King rank, but was disappointed by failure. He's encountered by Retsu Shaolong (having not yet achieved Sea King). Disillusioned with Retsu's past misdeeds, Ryu had no intention of letting Retsu become Sea King. However, Dorian recommended making Retsu a Sea King. Ryu obliged, stating that Dorian could never be mistaken. He is apparently 100 years old and has retained a massively muscled physique. He battles Yujiro in the Raitai's first battle, and loses badly. He fails to land a single hit, and has his face ripped off. He is able to stand and attack again despite this injury, but Yujiro dodges and kicks him square in the face again, taking him out for good. Retsu later learned that his master is still alive.

Kaiou Kaku (郭 海皇)

The Sea Emperor of the Sea Kings in Retsu's system of Chinese fist fighting, and current champion of the Raitai (the Chinese tournament of Sea Kings against Sea Kings), he is roughly 146 years old when first seen in the manga. He is a shrunken old man, even shorter than Baki, who is almost skeletally thin, has a severely receding hairline, and a fantastically wrinkled face, who requires glasses and gets around in a wheelchair when not fighting. Despite his advanced age, however, he is a phenomenally lethal and skilled fighter with an almost sociopathic ruthlessness and pride in Chinese fighting and culture, viewing all others in contempt. His skills, the result of over a century of training in Chinese martial arts, allow him to easily defeat a Muay Thai-using Sea King, who is a fifth his age, in less than ten seconds without sustaining injury. He can slice several human limbs off with a simple chop of his hand, and even injure and send flying Yujiro himself. Kaku's primary technique is called 'Shao-li' or hyposthenia punch, a form of bodily control that allows him to present zero resistance to oncoming blows. He absorbs the impact of attacks so perfectly that even Yujiro's punches at full force only give him a slightly bloody nose. This also allows him to put his entire body weight into his blows, along with the force of his opponent's own attacks. This allows his withered fists to blast craters in stone walls and injure Yujiro. It is Kaku who disrupts the structure of the Chinese tournament, turning it into a 'Chinese team vs Japanese/American team' match-up when the majority of other Sea Kings at the tournament prove disappointing and are easily defeated by Baki and his friends. He ends up battling Yujiro Hanma, and is shown to be one of the opponents that Yujiro respects. The match ends in a draw, and Kaku bestows the title of Sea King on Yujiro after the fight as well as a challenge to battle again in another hundred years. He surprisingly reappears in Baki: Son of Ogre, to help Katsumi in the fusion between the 500 years in karate and the 4000 years of Chinese martial arts.

Kaiou Jyaku (寂 海王)

A bald Sea King with beard and glasses, he uses a fighting style which focuses on not harming the adversary. He joined the Stranger Team when the Raitai had his rules changed by Kaku, and was defeated by Retsu during a long fight, in which Jaku focused on defense and managed to take many hits without being so harmed. In the end, Retsu hits his vertebral column, and takes him down with one punch in the face, despite this, Jaku remains standing even when unconscious, which leads Retsu to declare him the victor. He reappears in Baki: Son of Ogre, in the military base, searching to fight Pickle. He also has a tendency to ask other fighters to return to Japan with him.

Kaiou Han (範 海王)

Brother of Li and part of the Chinese team, he fights Alai Jr. and gets his face slashed before being defeated in one hit.

Kaiou Ri (李 海王)

Brother of Han and master of poisons, like Yanagi. He fights the poisoned Baki in the Raitai and manages indirectly to "heal" him with his poisoned hands, as a counter effect. He is then knocked out in two hits.

Kaiou Samwan (サムワン 海王)

A Thai-born Muay Thai user, Samwon is 25 at the time of the Raitai tournament. He had apparently been spotted and trained by another former Sea King while playing with a live cobra in the streets. While his Muay Thai skills were impressive enough for him to be granted the title of Sea King in China and qualify for the Raitai, they aren't nearly enough against Kaku, who pulls off his pants and flicks his testicles, paralysing him with pain and defeating him in a profoundly humiliating manner. He later attempts to take out some of his anger and frustration on Yujiro, an ill-advised move that ends with his head smashed into the floor. He has little respect or even belief in the more philosophical or mystic side of martial arts, believing that "whoever uses his body better, wins". This is what leads to his downfall against the more logical or intellectual style of Kaku. Samwon, or a character who resembles him, is briefly seen in the Underground Tournament arc of the anime as a champion of Muay Thai. He tries to fight Yujiro, who labels him as a hollow champion. Samwon launches a fierce attack, but his blows are blocked only by Yujiro's finger. Yujiro knocks him out with a flick on the forehead.

Kaiou You (楊 海王)

A Sea King specifically trained into having a "diamond body" (by a harsh training where he is hit by sticks, cars, torrents, rocks...). He defeats Dorian and then tests his body against Oliva's strength, but he is crushed by one hand.

Kaiou Jo (徐 海王)

A tall Sea King who fights again Alai Jr, he is rapidly defeated after not even landing a single hit.

Kaiou Son (孫 海王)

A Sea King focusing on a style with fingers, he is defeated in an arm wrestling match (or finger wrestling match) against Retsu.

Kaiou Chin (陳 海王)

A Sea King who fights Jaku and is distracted by his kindly nature, and then is beaten by having his arm twisted on the ground.

Kaiou Mou (毛 海王)

A fat Sea King who doesn't fight all because he is knocked out by Kaku with one finger in the chin, because Kaku changed the rules of the Raitai in the Chinese vs Stranger team.

Shobun Ron (龍書文)

User of Yami Kenpou (dark arts), an unbeaten fighter of the Chinese underground area hired by Kaku Sea King to make the Chinese team. He hardly speaks Japanese and is mainly silent. He fights Oliva and manages to wound him significantly with his Kiai (hidden stance) which focuses on a "pocket trick", mainly letting both hands in the pockets and then attacking (like a sword stance). However Oliva blocks him and defeats him with powerful headbutts.

Shunsei Kaku (郭春成)

Nicknamed "crazy beast", he was conceived when Kaku was 125 years old (He's his youngest son, 27 years old). He gets KO by Baki before even landing a single hit.

Baki Hanma characters

• Saman (サマン)

Voiced by: Tesshō Genda (ONA)

Leader of a special task force in Africa. He gathered many troops together to kill a raging elephant. The elephant was ten or more times bigger than a normal elephant. It was big enough to impale a lion with its tusks. Saman's weapons could not defeat it, and neither could anti-aircraft weapons. Yujiro came and killed the elephant without a weapon. Saman relayed this story to the news, only to be ridiculed.

• Rumina Ayukawa (鮎川ルミナ) - A grade-schooler who challenged Baki to become the strongest. Baki slapped him. Afterwards, Rumina was complimented for taking a blow. Baki then took Rumina to his home and demonstrated his shadow boxing.
• Jun Guevaru (純・ゲバル) - In the 'Son of Ogre' series, an 'alternative universe' version of the famous Che Guevara exists. Jun is a former pirate of the high seas who went on to found his own sovereign nation of 'La Serna'. His appearance is nearly identical to the real Guevara as seen in the classic photograph, and he is one of the three strongest men in the entire world, along with Biscuit Oliva (the second) and Yujiro Hanma (the first). Much like the real-life version, this manga version of Guevara is notorious for his radical political philosophy, his anti-captitalist and more specifically anti-US stance (the crime he is presumably imprisoned for is that he broke into George W. Bush's house and threatened his family, after Bush considered using bullying military tactics against La Serna despite the warnings of his advisors), and his harsh discipline. It is this discipline that has made him so powerful, as he is described as 'one of the three men alive more powerful than a machine gun'. He uses a fighting style developed from the exclusive use of bare hands against all weapon types, and so is quite capable of killing someone in a single hit. He can defeat an opponent who has a gun to his head, or destroy several abnormally strong and/or skilled opponents at once. He is first encountered in the Arizona prison, as he has intentionally allowed himself to be captured and imprisoned there in order to battle Biscuit Oliva, a man he sees as representing the strength and arrogance of the United States. He puts up a good fight against Oliva, but loses in the end after enduring several hits from Oliva's full strength, Oliva noting that he is the first man in ages to be able to withstand his full strength. Apart from these obvious differences in personality and ability, this manga version of Guevara is also much younger than the real-life version would be, being about mid-thirties at the oldest, with the manga being set in current times. He goes back to his country after his defeat.
• Chamomile Lessen (カモミール・レッセン)

Voiced by: Kensho Ono (ONA) (Japanese); Israel Adesanya (English)

One of Guevara's underlings, he infiltrated the secret service as a bodyguard of President Bush. While Bush was having a conference about military action in La Serna, Chamomile stopped him and informed him that Guevara's men have infiltrated every state.

• Samuel (サミュエル)

Voiced by: Taiten Kusunoki (ONA)

The coach and manager of Ian McGregor. he appears first in the Maximum Tournament arc, where he is very protective of Ian. He later interferes with Ian's match against Chiharu Shiba, costing him the fight. Samuel briefly appears in "Son of Ogre" at the Arizona prison. In the English dub of the anime, it is said that Samuel is Ian's stepfather. Neither the Japanese version nor the manga make such indications, however.

• Mouth (Lips, Teeth, and Tongue) (唇（リップ）・歯（トゥース）・舌（タング）) - Identical triplets who have a knack for finishing each other's sentences. They are formidable soldiers sent to fight Ian McGregor to ensure that he can't start his boxing career again. Fighting all at once, they beat Ian nearly to death, but Jun stops them. Jun urinated on Tongue, who unleashed much profanity before being beaten by Guevara. With a core member defeated, Lips and Teeth knew they could not win and retreated, to which Guevara casually said, "As usual, the Tongue was the only one who got dirty".
• Maria (マリア) - A morbidly obese woman and the lover of Biscuit Oliva. Oliva is stunned by her beauty, so much that he says that a handkerchief from her hometown has the most intense scent. However, Maria constantly belittles and insults Oliva. She watches the Guevara/Oliva fight from atop her king-sized bed. It is later revealed she was once a slim and incredibly attractive woman, but an unknown disease and the drugs used to treat it caused her massive weight gain, possibly affecting her metabolism. Oliva continues to love her because her attitude and bearing never changed despite her hardship.
• Pickle (ピクル)

Voiced by: Takeshi Kusao (ONA)

A primitive form of man found perfectly preserved in a saline rock formation (hence he is 'pickled') this giant humanoid supposed lived originally in the Jurassic/Cretaceous era. He is revived from his long suspended animation in Baki 10.5, and is sent to Japan by Strydum after he defeats entire army battalions and even a high-tech exo-skeletal powersuit sent against him. Pickle does not resemble any form of primitive man (Neanderthal or Cro-Magnon) or even modern humans, standing taller than Jack Hammer and possessing a level of muscular development equivalent to Oliva, this has led some to believe Pickle is a missing link in the evolutionary chain. He possesses upper and lower exaggerated canines, giving him a 'fanged' appearance, and his nails resemble claws. His muscles are so developed and powerful that he withstands three 9 mm. shots to the stomach at point blank range, none of which penetrate his abs, and indeed he believes the man who shot him to be engaging in some sort of rough-house 'game'. He hunted, killed and ate T-Rexes without the use of weapons in his prehistoric life, and is one of the most blatantly superhuman characters in the entire manga. He has never been heard to speak intelligibly so far in the manga. His strength is shown in various occasions, being capable of withstanding a strength test with Yujiro himself, resisting a charge from Hanayama, sending Baki flying through the Korakuen arena with a single kick, chopping a leg from Retsu after beating him, and enduring Katsumi Orochi's attacks and taking his right arm, then praying over the severed limb to show his reverence and respect for Katsumi. When fighting Jack Hammer he lost his left ear to a bite attack after ripping off the flesh from Jack's jaw. He goes mad after this and beats Jack senseless. In Baki's battle against Pickle, Baki's adaption of dinosaur-like stances has led Pickle into believing that he's as dangerous as the only creature that ever defeated him during his youth: a wasp. He defeated Baki with a shoulder throw and began to roam the city freely, learning to speak Japanese and eventually interrupting Baki and Yujiro's fight in order to ask Baki for a rematch. Baki then roundhouse kicked him and stunned him, forcing him to sit and watch the fight from the sidelines. As time has gone on, Pickle has somewhat adjusted to civilization (i.e. wearing clothes and only killing animals that present a danger to others), though he prefers living alone in the sewers to living with other people.

• Dr. Albert Payne (アルバート・ペイン) - A nobel prize winner. He appears to be very knowledgeable about Pickle, whom he views as a treasure to the human race. Thus he harshly rebukes anyone who tries to defame Pickle, saying that his acts (i.e., sexually assaulting a female reporter, killing and eating an endangered tiger) are only natural to him in his time and thus is not wrong. He is based on Albert Einstein.

Other characters

Yuujiro's Mother (勇次郎の母)

Yujiro's mother and Baki and Jack's grandmother. Her face is never seen and her name is unknown. Apparently Yujiro was her first and last child, after which she apparently went into a monastery. She has great feelings of shame, fear and disgust for her monstrous offspring, and is unaware of the existence of Jack and Baki.

Yuuichiro Hanma

Voiced by: Hidekatsu Shibata (ONA)

Yujiro's father and Baki and Jack's grandfather. He briefly appears during the fight between Baki and Yujiro as a shadow image and gives Baki words of encouragement to beat Yujiro. As Tokugawa purported, Yuichiro is the only other being to beat the United States before Yujiro did so. His special technique was nicknamed "Dress" by the USA military and it consists of grabbing the opponent and using him as a human nunchaku.
