I never once planned to live a long life! I've long been ready to exchange the strongest body ever for death.

– Jack to Dr. John.

Jack Hanma (ジャック 範馬, Jakku Hanma) is a fictional character from anime and manga series of Baki the Grappler. In the English dub, his name has been changed to Jack Xamma (pronounced "Zah-mah").

His ringname is Jack Hammer (ジャック・ハンマー, Jakku Hanmā).

Personality[edit | edit source]

Jack's driving force is wanting to defeat his father, Yuujiro Hanma, to avenge his mother who was raped by him. Jack turned into a monster without balance who only cares about becoming stronger to take revenge, thanks to his super steroids that make him beyond unstable, that refuses to hold back against his opponents; and, speaking of behavior, he prefers to act like a wild animal rather than a true fighter, as especially shown how he bites his opponents during their fights, making him even more animalistic. Jack can indeed seem very frightening to his enemies: for example, he startled Pickle after Jack lost to him, because there is nothing in the wild that prepared the caveman to the sight of a prey seemingly coming back from the dead for a rematch. He almost out-savaged Pickle during their fight and the caveman came to see him as a wasp, the only creature he fears.

He sees his brother, Baki Hanma, as a rival, but also likes and cares for him deep in his heart as they have the same goal in surpassing Yuujiro. Following his defeat at the hands of Baki, he became more humble and amicable towards his half-brother. He learned to calm down and grow friendlier towards others. He also has perfect table manners and sometimes feeds the koi with little old man Tokugawa. Jack also seems to have some feelings for his younger brother's girlfriend, Kozue. When he first meet her in the Maximum Tournament, he flirted with her, although perhaps it was only to provoke his brother.

Jack is an incredibly determined and stubborn person; he just doesn't know when to quit. His overtraining would be suicidal, if not for a mad scientist's steroid cocktails being part of his regimen. He's had his skeleton surgically restructured multiple times to get bigger. Even having half his face bitten off by Pickle and waking up in the hospital twice, the second time from a severe coma, he still gets up and goes right back to it. Also, it can be said that he is sometimes too confident in his strength. He trains too much for his body to handle, forcing him to resort to steroids and other medical methods in order to keep his strength growing steadily. He is too obsessed with beating Yuujiro and avenging his mother, to the point where he is blinded by that dream. He doesn't know a lot of techniques and often fights head-on.

Jack's intelligence is relatively average. Although he has shown himself to be a slightly bit of a combat genius from times to times (as he was able to counter Shibukawa's Aiki), that is likely due to his lineage as a Hanma and the son of Yuujiro Hanma.

Appearance[edit | edit source]

Jack Hanma in the manga.

Jack trained so hard that his muscles became completely destroyed. He took an experimental drug known as the x4 to strengthen his body, regardless of a scientist warning it might kill him, he underwent extreme pain from the drug surviving due only to his Hanma blood line, the drug caused his muscles to become extremely large and strong. Unfortunately, a number of drugs eventually managed to destroy his body again, and drastically reducing his life expectancy in the process. But later, Jack managed to repair his body and he became even stronger. In the second series of the manga, he underwent surgery to make him taller and stronger. Kureha Shinogi carried out the operation, and thanks to that fact the desired effect was achieved. Kanji Igari stated that Jack is even bigger than Mount Toba.

His physical features include blue eyes, a piercing gaze and short blonde hair and rather large eyebrows. He's often wearing a blue t-shirt, long jeans or shorts. In the third season of the anime, Jack's eyes are brown. It can be said he looks very much like Yujiro in terms of his facial appearance and his physique looks to be similar to his grandfather Yuuichiro. The only thing he has from his mother is her hair color.

Jack is an extremely tall and muscular man. His initial height was 6'4 (193 cm), which changed to 6'11 (213 cm) after the Maximum Tournament thanks to Shinogi Kureha's limb-lengthening surgery, and finally to 7'11 (243 cm) after Jack's fight with Pickle, which was once again achieved by the limb-lengthening surgery.

History[edit | edit source]

Baki the Grappler[edit | edit source]

Past[edit | edit source]

Diane Neil, Jack's mother, was a secret agent whose job was to get rid of Yuujiro Hanma during the battlefield. When the Ogre discovered that Diane was trying to outsmart him, he decided to take revenge on her and raped Diane. That's how Jack was born. Yuujiro, unlike with Baki’s mother, did not kill her and Jack’s mom decided to keep the kid. Unlike his half-brother Baki Hanma, he has since childhood wished to surpass his father Yuujiro Hanma in strength and martial ability to get revenge rather than earning his love and respect (later, Baki also wanted to get revenge, of course).

Jack's former look.

His obsession to defeat his hated father led to extreme over-training at various fighting gyms which led to the deterioration of the muscles in his body. He wasn't much more than skin and bones because his body had been damaged by overwork. For example, Jack would punch sandbags for over 12 hours without eating, resting, or even using the restroom and would lift weights until his body refused to do anymore. He claimed he will never be able to defeat his father with normal training. After his encounter with the Yuujiro-inspired scientist named Dr. John who witnessed Yuujiro killing a polar bear, the scientist promised him great results if he tries using a special drug which he called X-4. He received from him a concentrated formula of steroids to match his over-training and gained immense power in the process, though in the process Jack had become addicted to the drugs and began overdosing leaving him even more mentally unstable. At first, the doctor was happy with Jack's results, but at one point he tells the Canadian that he's really starting to overdo completely, although the doctor finally agreed to give Jack as much drugs as he wanted. Like Yuujiro, he became powerful enough to kill a polar bear with his bare hands, but with his unstable mindset he was more brutal and made it's death agonizing.

Maximum Tournament Saga[edit | edit source]

Jack appears in the Maximum Tournament in the Underground Arena, but introduces himself as "Jack Hammer", in order to not reveal his true identity to everyone. Before his first match begins, Jack meets Kozue Matsumoto in the hallway of the Underground Arena. He starts talking to her like he's trying to flirt. Suddenly, angry Baki appears and shows a very militant attitude towards Jack. The Canadian fighter just turns around and tells Baki he wants to see him in the finals.

Jack fighting Sergio Silva.

Jack's first opponent is Sergio Silva, the Brazilian grappler. The fight is quite short and very one-sided. At the beginning of the fight, Sergio catches Jack with some grappling hold, but he is completely defenceless against the destructive power of the Canadian, who easily comes out of the hold using just pure physical force. Silva doesn't have the slightest chance against Jack, who eventually sends him into the air with an uppercut and wins the match. After the fight, Yuujiro Hanma enters the arena to talk to Jack. Yuujiro sees that Jack's using drugs to strengthen his body. After a while, he gets excited and tries to start a duel with him, but then Baki enters the arena, kicking Jack in the face. Baki screams that Jack has no right to fight the Ogre and he is the only one who will defeat him. Jack tells him that Baki's not the only one who has the right to do so, but it is unknown what he really want to say by it. Annoyed Yuujiro knocks Baki out so he won't disturb them, and after a while Jack whispers something in Yuujiro ear that makes him very happy. The Ogre smiles and announces that Jack has a great right to fight him. The Canadian competitor leaves the arena with a cold and calm expression.

Jack biting Misaki Kengo.

Before starting another fight in the tournament, Jack meets Alexander Gallen in the locker-room and tells him that he is interested in a fight with him. A tense and conflicting relationship begins to form between the two competitors. In the second round, Jack's opponent is Kengo Misaki, the Japanese master of Shorinji Kempo. Misaki tries his Shorinji Kempo techniques, but nothing works. Something strange happens during Misaki's rush, because his hand is flooded with blood. For unknown reasons, it turns out there is a wound on it. At some point in the battle Misaki knocks Jack to the ground and starts bombarding him with kicks from above. However, this time a wound on the foot of the Japanese appears unexpectedly. During their fight, Jack uses his teeth to bite Misaki's body. He tears his hand and leg apart with his teeth, doing it in such a discreet and instant way that nobody notices that he used his own teeth. Mitsunari Tokugawa even interrupts the fight to see if Jack is using some kind of weapon. When it turns out that Jack doesn't have any items with him, the fight continues. The Japanese is trying to use another Shorinji Kempo techniques, but this time the Canadian fighter stops hiding the using of his teeth and bites into Misaki's hand in front of everyone, then knocks him out with a brutal punch.

After the match, Jack meets Alexander Gallan again, but this time in the hallway. Gallen accuses him of being disgusting in his fighting style that is not graceful at all. Jack explains to him that he sees the fighting in a slightly different way. At the end of the conversation, Gallen just adds that he can't wait to fight Jack and goes away slowly.

Jack punching Gallen.

In the third round of the tournament, the dispute between Jack and Gallen is finally resolved, because Gallen is the next opponent of Jack. At the beginning of the match, Gallen dominates and hits Jack with his fists, performs suplex on him and then manages to perform his powerful technique called Gallen Special. At some point, however, Jack decides to start some counterattack and eventually almost bites off two of Gallan's fingers. The Russian is furious that Jack has disfigured the body representing Gallen's homeland and rushes at the opponent, but then Jack attacks with a powerful uppercut and then starts bombarding him with the violent blows. The Russian wrestler takes a lot of damage, but in an act of desperation, he still tries to perform a suplex. However, the Canadian neutralizes his technique and throws him into the arena fence. Gallen clearly begins to lose the fight, which Jack ends with a powerful nukite aimed at the ribs and a brutal punch to the heart. Gallen spits out a lot of blood that makes Jack's face dirty, and then the Canadian is declared a winner.

Jack vs Shibukawa.

In the semi-finals, Jack faces Gouki Shibukawa, the old jujutsu master. Before the match begins, Jack makes a show of strength in the arena. He pulls out a big coconut and starts tearing it apart with his own teeth. Shibukawa takes a sip of water just before the start of the battle, and after a while shoots a water from his mouth towards Jack. The shot hits a vital point called the "tear cable". It's a trick that makes Jack feel like he's drowning in water for a while. Shibukawa goes on the offensive and throws him very hard on the ground and then jumps on him with a kick while Jack is lying on the arena's floor. Shibukawa thinks it's the end of the fight and wants to leave the ring, but Jack suddenly bites his ankle. The Canadian attacks Shibukawa in various ways and starts to dominate, and the old jujutsu master defends himself using his special weapon called Aiki. Jack repeatedly tries his brutal attacks on the old master, but each time it ends with his fall to the ground. Soon, however, Jack finds a way to deal with this technique. He decides to approach the old man very slowly, so that he wouldn't be able to give back the impact power and knock him over again. In this way he bites his hand and then attacks Shibukawa with a few brutal blows. At the end of the fight, Shibukawa tries to use some technique with the last remaining force against the opponent, but when he clutches his hands on the Canadian, this time it is Jack who uses Aiki and throws the old man to the ground, finishing with a kick from above. Shibukawa lies semi-conscious on the ground, and Jack is declared the winner and leaves the arena.

When the match ends, Jack is stopped in the hallway by Shinogi Kureha, who advises him to not take part in the final fight because of too much drugs that Jack's body has taken. Kureha says the Canadian fighter's body will be completely destroyed in the next fight. Jack laughs at him and ignores his warnings. Desperate Kureha tries to use force against Jack to stop him, but it turns out to be completely ineffective. The Canadian tells him he's stronger even when the drugs does't work anymore. For a while, they're arm wrestles with each other and Jack wins easily with one hand. When the Canadian fighter leaves, Kureha still screams that Jack is about to die, but any attempt to convince him is futile.

Deformed Jack kicking Baki.

The final fight is coming up, and Jack's gonna face Baki. Before entering the ring, Jack meets Yuujiro in the hallway. They talk for a while and Jack tells him that he's going to beat him next. A Canadian fighter enters the arena in a coat with the "Jack Hanma" inscription, thus revealing his real name to everyone for the first time. The brothers shake hands before the fight, smile at each other and promise to do their best. From the beginning, their fight is very fierce and both combatants performs their best techniques. At some point, Jack bites through Baki's brachial artery, but he quickly bandages his wound to lengthen his time before he bleeds out. Eventually, Jack's body starts to deform due to too much drugs he took, and he starts screaming and vomiting painfully in the arena, but does not intend to stop fighting. The "mutated" Jack beats his brother with a lot of blows, but Baki keeps fighting and eventually decides to use the Front Neck-Lock. Jack gives his best to withstand his brother's grappling technique, but eventually loses consciousness. After the match, Jack helps tired Baki raise the winner's belt. When Jack leaves the ring, he meets his father Yuujiro again in the arena's corridor and after telling that he's finally ready to fight him, Jack attacks Yuujiro. Unfortunately for him, Yuujiro counterattacks, biting him very brutally and then knocking out his son in the blink of an eye. Jack Hanma falls to the ground and Yuujiro gets mad at him for losing twice in one day.

Most Evil Death Row Convicts Saga[edit | edit source]

After the Maximum Tournament, Jack has Kureha Shinogi perform surgery to lengthen his bones where multiple of his bones were broken and he had his limbs lengthened in 8 places. Jack is then first seen by Kaiou Retsu in a restaurant where Jack orders an entire roasted pig for himself and eats it in 10 seconds, even though Retsu is at first unaware that it's Jack and judges his height, saying it could be more than 210 cm. Jack then stands up and walks up to Retsu and says that he just remembered who Retsu was and that he saw him in the underground arena and at the Maximum Tournament. This shocks Retsu and makes him realise that it's Jack. He afterwards wonders on how Jack managed to gain 20cm (Jack was 6'4 the last time they met, meaning that Jack is 6'11 at this point in the series). Jack silently walks away with Retsu looking at him, still wondering on how Jack grew so much in less than a year.

Jack with Shinogi Kureha.

After this, Jack goes on to another restaurant with Kureha Shinogi, where Jack orders a T-Steak and ends up eating the bones like biscuits, leaving the waiters surprised and wondering if he's a professional wrestler. Meanwhile, Kureha compliments Jack's growth rate, calling it a miracle, and explains the limb-lengthening surgery Jack underwent in 8 places after the Maximum Tournament. It turns out that after the tournament they established a much more friendly relationship than at their previous meeting. After he finishes, Jack says that he doesn't care about brotherhood, but he can be the one who gets revenge for Kureha Shinogi. This is probably a reference to the loss Kureha suffered from Jack's half-brother Baki Hanma in the Underground Arena. However, it can be also a reference to the fact that Hector Doyle almost killed Kureha's brother Koushou Shinogi.

Later, Jack is seen confronting Sikorsky, the Russian serial killer and one of the five death row convicts. He tells Sikorsky that he is simply an enemy to him and asks where should they fight, mentioning that the police in Tokyo can be annoying. They decide to fight in an empty public bathroom. Jack strikes first with a punch which Sikorsky barely avoids. Sikorsky then grabs onto an emergency fire extinguisher on the ceiling with his thumb and index finger and kicks Jack in the face. Jack shakes off the attack and compliments Sikorsky's finger strength, before questioning for how long he can hold on like that. He charges at Sikorsky again and grabs his leg, making Sikorsky repeatedly kick Jack in the face with the other in order to release himself, but Jack punches Sikorsky so hard that Sikorsky breaks the emergency fire extinguisher and flies of to the end of the bathroom and throws up. After this, Jack and Sikorsky go to a phone booth where an unsuspecting civilian Shou is making a call. Sikorsky enters first and Jack second. After a short fight, Jack knocks out Sikorsky and orders for the phone booth to be transported into the coliseum via a truck. It turns out that Jack was helped by Kanji Igari, who wanted to take revenge on Sikorsky for insulting and beating him up.

Jack fighting Sikorsky.

After this, Jack enters the arena while the truck releases Sikorsky and Mitsunari Tokugawa explains the situation to him. Sikorsky then starts yelling loudly before taking off his shirt and screaming: "давай!", which in this context means "bring it on!" in Russian. Sikorsky strikes first and Jack tanks his strikes, only to lift Sikorsky up after Sikorsky tries to push Jack into the wall. Jack throws him into a wall on the opposite side and then rushes to him and kicks him so hard that Sikorsky flies into the audience. Sikorsky then decides to take an old man's staff, as well as a nail from a wall broken by his body while he was being tossed by Jack, and use them as weapons. Jack notices this and lets Sikorsky use the staff as a spear. Sikorsky tries to stab Jack, only for the spear to stop without piercing even his abs. Jack says that unless it's an actual spear it won't pierce his abs. Sikorsky then throws the wrinkled nail in Jack's face, but Jack catches it with his teeth and proceeds to chew it. After a short while he spits the nail out, showing that he almost made it into a gum thanks to his incredibly strong teeth. Seeing this, Sikorsky thinks to himself that Jack isn't human while Jack says that it's time for a switch and that Sikorsky will get a opponent worthy of him. At this point Gaia starts walking into the arena while Jack starts leaving. They meet half-way and Jack gives Gaia a high-five before exiting the arena.

Abilities[edit | edit source]

One of his main techniques is the biting, and he can bite hard enough to easily crush wood with his teeth. He claims that his teeth can tear a coconut. Jack could eat a whole roasted pig in 10 seconds and could chew on the bones of a T-bone steak like it was a biscuit, thanks to the amazing power of his teeth. Although he lost all of his teeth during the process, his bite can still damage Izou Motobe when he wears chain mail made of Aramid fibres, which is made for planes and tires. His body is strong enough to surpass drugs, even though he used abnormal amounts of them. Due to his super steroids Jack had a tendency to fight like a rabid animal and has severe determination skills which proves this even further.

His strength is shown many times in the story: killed a polar bear with his bare fists in the same way his father did, defeating the convict Sikorsky with a punch so strong he lifted the telephone box where they were located in that moment, and withstood his knuckle slash in the underground arena, taking many blows from Mohammad Alai Jr and defeating him, cutting Ali's tongue in the process, fighting Pickle despite some strength difference and making him run away in fear of the only creature that scares him, a wasp.

Despite using brute force to fight, Jack is a very tactical fighter, and is smart enough to counter and outmaneuver his opponents. For example, he made Chiharu Shiba pass out with a special type of a hold where Jack presses two fingers on the gang leader's vital points that are located in the throat (Baki defeated Gaia with a similar way; except that Baki did it with two hands, while Jack only used one hand) and also when he found the weakness of Aiki after being thrown many times and used a similar move to defeat Gouki Shibukawa. During his fight with Pickle, Jack tried to strike his middle fingers into Pickle's ears, piercing his brain. He used this as a last-ditch attack, because he was about to be knocked out and used his fighting spirit to activate this technique. This move may have possibly killed Pickle, if the massive powerful caveman hadn't managed to sense Jack's upcoming attack.
