|“||Strong men have a smell... You can search the world over and still not come across a smell like this... It's my favorite aroma!||”|
– Yuujiro during his first battle with Baki.
Yuujiro Hanma (範馬 勇次郎, Hanma Yūjirō) or Yuujirou Hanma, is Baki and Jack Hanma's father. He is the primary antagonist of the entire Baki franchise. Yuujiro is the son of Yuuichiro Hanma and the strongest character in the series thus far. Yuujiro works as a highly-paid freelance mercenary and assassin for various governments and organizations. It is unknown how much people or organizations pay him to do his mercenary job, but it is extremely high, judging from his expensive taste.
He is often called "the Strongest Creature on Earth" (地上最強の生物, Chijō Saikyō no Seibutsu) or "the Ogre" (オーガ, Ōga).
Yuujiro is a fierce and arrogant man. He shows no mercy towards anybody, as he views mercy as a "weak" trait. Yuujiro is also emotionally manipulative - this can be seen in his relationships with his son and Emi Akezawa, for example. He seemingly lives only to fight and cause destruction to anything and everything he can. His whole life and mindset are dedicated to nothing but fighting and growing stronger with each person he defeats, sometimes killing them. He tends to kill people if pushed or enraged enough and does not show care or remorse when doing so. He will also kill for pleasure or satisfaction when he feels like it. He has a deep resentment for the weak and does not even think it's worth killing them. He desires his son Baki to become strong like him, so he can enjoy a challenging fight with him as if Baki is a toy to him. He is also unexpectedly silent and stoic most of the time.
He is also ruthless, as shown when he ripped Kaiou Ryuu's face-off and then slammed his skinless face onto the stone floor. Another example would be when he killed Emi Akezawa by rupturing her eardrums and then breaking her spine. He is a very arrogant man, believing and knowing that he is the most vital living creature on Earth, and he feels inclined to do whatever he wants, with no one being able to stop him. He views everyone else as insects compared to him and sees them as "the weak." He believes that everything should be obtained with pure strength alone and therefore does not believe in using weapons. He considers his body as the ultimate weapon, which proves to be more effective and deadly than any other weapon or technology. Since his fight with Baki went viral, Yuujiro is annoyed that he has gained unwanted fans and has referenced several young children asking for his autograph since the fight. Despite being wrathful, Yuujiro is surprisingly patient and almost always keeps his cool. He is stoic most of the time, often speaking only what is needed and even just what is necessary. In truth, most of the time only silently listens to others and sometimes adds something and can keep his cool even when he is insulted. Although enough is enough, he can be very violent, and he almost instantly switches back to his usual calm demeanor.
Yuujiro does have a somewhat "soft" side. Offering Baki some soup as a sign of respect for his power after an eventual tie between him and his son; also trying to avoid telling Kaoru Hanayama the fact that he signed an autograph for a kid out of embarrassment. He's also shown to, despite having killed her, possess some affection towards Emi (and even seemingly regret what he did, but it is hard to say) as shown when he says to Hinary that he would protect whoever had close ties with Emi. He even fought for the weak in wars to be, in his words, a "role model." Because he was obliterating their oppressors, the weak started to see him as something sent from God. Even Musashi Miyamoto has stated that "there is a kindness" to Yuujiro.
Yuujiro unabashedly interferes in Baki's affairs by creating destructive challenges for him to overcome and develop from. It should be noted that despite his oppressive and generally hands-off parenting style with Baki, he wants him to become stronger. His motives for this are a mixture of Yuujiro's parental projection of Baki following in his image as a legendary fighter and the potential of creating a stronger opponent for himself for entertainment. He encourages Baki to have sex with Kozue Matsumoto, which eventually triggers his transition into manhood and a drastic change in Baki's fighting maturity which is seen during his fight with Ryuukou Yanagi.
It is common knowledge that Yuujiro is the father of Baki and Jack Hanma, but he states in a conversation with Mohammad Alai who invited him into his home to meet his son that Yuujiro has fathered many children throughout the world who remain unknown to the plot. No one knows for sure how many half-siblings Baki has in addition to Jack as there exists no record of the extent of Yuujiro's bloodline. Knowing this, and knowing Yuujiro's other personality traits such as arrogance, cruelty, and selfishness, as well as very little care for his children aside from Baki and Jack, it can be safely said that Yuujiro has the mind of a psychopath.
Beyond his philosophy and time spent training or fighting, Yuujiro is fully capable of living in modern society. While not stated, it's shown that Yuujiro has access to considerable resources, most likely in the form of connections or favors from some of the most influential people in the world. Given his power and threat level, this is not surprising. Other resources also most likely include a vast personal fortune. This is very clear from how Yuujiro has demonstrated sophistication and his ability to carry himself in high society. Yuujiro has sharp tastes, and whenever attending places of refining or meant for the elite of society, he can blend right in by both dress and manner. Since Yuujiro is the strongest in the world and sees himself as a king, this may be his way of trying to act in a way becoming of a king. He's also shown to be erudite, intelligent, and well-read in various topics, some of which are pretty esoteric.
During his 16th year, Yuujiro was quite different from his current self. He was much calmer, less savage and, not so bloodthirsty, most of the time defeating just his adversaries and destroying their vehicles. However, over the next two years on battlefields, Yuujiro's desire to fight and bloodlust grows exponentially and mercilessly kills everyone who stands in his way, making him the man he is today.
It may be that compared to his youth, the current Yuujiro has had the chance to calm his personality and temper his instincts. Perhaps as an extension of his manners and desire to project an image of sophistication, Yuujiro can be an excellent company to anyone who has earned his respect or consideration. In these instances, he has no problem getting along with the people he has acknowledged. He accepted Baki's request for a quiet dinner together, where despite Baki's resentment towards him, he admitted that he enjoyed the meal with Yuujiro immensely. He's also gone out for drinks with Doppo Orochi, possibly because Doppo gave him an exciting fight in the past and managed to survive. He also rejects the Kaiou title given to him by Kaiou Kaku by claiming that his feelings are enough. He later complemented Izou Motobe to Musashi by claiming Motobe fights for real and is ready to do anything to win while commenting on how Motobe was rewarded for his hard work by finally being able to face Musashi where Motobe could use all of his skills and moves.
Yuujiro is an extremely well-built man standing about 6'3" and weighing about 265 pounds (190 cm and 120 kg). His neck is exceptionally thick even compared to the rest of the fighters (rivaling Pickle and Yuuichiro), and his legs are extensionally long. Yuujiro has red wavy hair, thick black eyebrows, and red eyes (brown in Baki 2018 and 2020 anime series). Although Yuujiro isn't as tall and so over muscular as some other characters and has a more athletic frame, vast shoulders, chest area, and, somehow, less or at least slimmer legs. Despite that, his body is still trained to the utmost limit. His abnormal back muscles take the shape of a demon when he gets serious in a fight. He is usually shown wearing his signature dark red shirt and pants in the anime and black shirt and pants in the manga, though he is also shown wearing a black shirt and pants in the anime's third season. During his first meeting with Mohammad Alai, he was dressed in blacktop, green military pants, and loose sandals. Most of the time, he is seen with a cold, stoic expression.
Even as a teenager, he already had his impressive height and was very muscular, though not as later. He wore a soldier outfit consisting of green military cargo pants without a top and boots, and a green bandanna. He later adopts a ponytail for a short while, eventually leading to his present hairstyle. Yuujiro's appearance can be likened to an ogre or lion (as this was Keisuke Itagaki's intention).
Baki the Grappler
When Yuujiro was 16 years old, he went to war to fight and develop his skills. He was in the Vietnam War, where he fought against the Americans. After the famous "Bloody Mary" bombardment plan was completed, Yuujiro survives as one of the two rebels. The second person is a woman named Jane. After a short conversation, she suggests Yuujiro to have sex, but he refuses. She laughs at him and tries to dominate him, but the Ogre catches her by surprise and says that he is the one who rules and could kill her at any time. Yuujiro and Jane become companions.
While American soldiers march and watch the ruins after the "Bloody Mary" operation, Yuujiro lurks among the ruins and attacks General Sam Gary. He kills him, takes his skin off his face, puts it on his own and shows himself to the other soldiers, pretending to be semi-conscious. The soldiers take him to some headquarters, thinking he's their general, who needs help. When in fact, their general is long dead and Yuujiro has made his way to the center of the nearby American headquarters. He slaughters the army in the middle of the building and meets a soldier named Gerry Strydum. During this time, the American army gathered around the headquarters to shoot the whole building with cannons to get rid of Yuujiro. Suddenly, Jane shows up with a big barrel of explosives. She tells Yuujiro that the barrel will cause a big explosion when the army will start shooting. Jane, suspiciously, finds a secret passage to the underground exit and then starts to run away with Yuujiro. Unfortunately, the Ogre guessed Jane's true identity. Her real name is Diane Neil and she's a Canadian spy of the United Nations. Her task is to lead Yuujiro through this underground passageway, where the UN army awaits the end. Yuujiro rapes Diane Neil to take revenge on her, then goes outside and destroys the army waiting for him. Nine months later, Diane bears his child.
The anime shows another retrospective from the time when young Yuujiro fought on the battlefields. America still tries to get rid of Yuujiro and sends all its best units against him (the Green Berets, the SEAL, and the Delta Forces). However, the young fighter defeats all of them. Ultimately, the Americans turn to Biscuit Oliva, who is a powerful man and a vip convict in the Arizona prison. Oliva is hired to get rid of Yuujiro under the pretext of eliminating some drug cartel dealer. Oliva introduces himself to Yuujiro when they meet, and the young fighter lets him know that he knows who Oliva is. The prisoner is happy with this fact and starts a short fight with him, but after a while Yuujiro runs away, saying that he prefers to leave Oliva for another time. At the end, America decides to form an alliance with Yuujiro. In other words, USA is completely defeated by one man, Yuujiro Hanma.
Yuujiro once appeared at a big and expensive banquet. In this place, for the first time he meets Emi Akezawa, who comes there with her husband Eiichi Akezawa. Yuujiro and Emi almost immediately notice each other in the crowd and starts to look at each other. Yuujiro undresses her with his eyes, so jealous Eiichi enters and starts talking to Yuujiro. Eiichi spills champagne on his suit, for which Yuujiro gives Emi a kiss. Angry Eiichi attacks him, but Lorion Grassy, a Brazilian Judoka, stops them. The fighter wants to defend Eiichi, challenges Yuujiro and loses quickly. Later, Yuujiro breaks into Akezawa's mansion, knowing that Emi likes him. He asks where Emi is and then kills Eiichi before her eyes. After a while, Yuujiro embraces and kisses Emi, telling her that he likes the bloodthirst in her eyes. He also confesses to her that he wants her to be the mother of his child. Soon after that, Baki is born.
In this saga, Yuujiro appears for the first time during the duel between Baki and Kaoru Hanayama. He appears when both fighters have finished their fight. Yuujiro ridicules them and states that this battle should not end yet, since they are both alive. The provoked Hanayama attacks Yuujiro, but he can't do anything. Baki tries to help his rival, but is knocked out with one blow by his father. Eventually, Hanayama is almost destroyed by the strongest man in the world. He easily knocks Hanayama out, stating that he only lost his time to meet such weaklings.
Later Yuujiro visits Emi Akezawa, who is surprised and happy seeing him. She tries to throw herself into his arms, but he rejects her and criticizes her for not having brought up Baki in proper way, stating that their son is still too weak. He also tells her that he will now take their son's development into his own hands. After a while, Emi gets angry and rushes with a razor at Yuujiro, who easily stops her. Her bloodlust makes him happy and he kisses her. Eventually, Yuujiro says that he will "test" Baki, which Emi has trained so far. Soon after that, Yuujiro goes to the mountains and kills Yasha-Zaru. He does it only to bring and show Baki the head of the ape, with which his son made friendly relationship. Yuujiro is meeting with Baki during the boy's training. He shows him the head of a dead monkey, and Baki goes crazy. Yuujiro manages to provoke his son and desperate Baki tries to attack him. His father stops him and says he wants to fight him next month.
Some time passes and Strydum comes to talk to Yuujiro. During the conversation, the Ogre learns that Baki defeated Gaia, the master of the battlefield. Baki's father states that this is not a great feat at all, and decides to do something much better than his son did. He calls the Prime Minister of Japan and says he'll be here in an hour to kill him. Then he really shows up at the Prime Minister's mansion and defeats a huge number of guards on his own, and then he shows up in the Prime Minister's room and raises his leg up to make a kick. The Prime Minister thinks he'll be murdered, but Yuujiro only breaks his desk. He tells him that he should take better care of his protection, and then he leaves.
Before the big match with Baki, Yuujiro visits his old friend Kanamoto, who likes to hunt. They're talking about the fact that Yuujiro is going to fight his son. Kanamoto begins a short philosophical speech about what a fight is for Yuujiro, but suddenly the Ogre interrupts him, saying that he did not come to visit only to drink his "bitter tea". Kanamoto shows him his great and powerful bow, which he constructed by himself, and Yuujiro urges him to shoot him. The old friend finally agrees, but the Strongest Creature on Earth easily stops the arrow flying in his direction. Shortly afterwards, he meets with Emi at the hotel. She wants to show him her crazy love and have sex with him. Then Yuujiro tells her that he is not interested in her at all, and that if Baki disappoint him in the fight, he will break contact with her. When he leads her to an emotional breakdown, she asks if she can stay the night anyway, but he wants her to leave.
When the day of his fight with his son comes, Yuujiro is attacked by Gaia, who wants to test his skills. Gaia, of course, loses the fight, even though both fighters have long been considered by people as equals. Later, Yuujiro arrives by helicopter at the duel scene, where Baki and many of his friends are waiting. The first of the helicopters gets off the humiliated Gaia, who kneels down by Yuujiro. The Ogre is also accompanied by Emi Akezawa, Hitoshi Kuriyagawa and an old soldier known as Sir. The big match starts with an unexpected earthquake. Yuujiro stops it by hitting the ground. Everyone is surprised by the great power of Yuujiro. Baki tries not to worry about this unusual show of strength and attacks his father. Baki does his best during a fight, but is unable to give any serious damage to his father. Yuujiro is still very satisfied with the level of his son and happily announces to Emi that today he will "eat a delicious dish". At some point, excited Yuujiro starts brutally knocking out his son and almost killing him, but is stopped by Emi who, in such a critical situation, decided to protect her child. Emi attacks Yuujiro with a blow to the face, and Yuujiro is surprised that Emi "finally started to be a mother". However, eventually the Ogre hugs her for the last time and breaks her spine. Then Yuujiro gets into a crazy mood and knocks out all the people who came to watch the fight. And then he just leaves the crime scene.
Underground Arena Saga
Yuujiro initially first appeared when he was mentioned by Izou Motobe in early chapters of Grappler Baki as a form of foreshadowing. Yuujiro made his first proper appearance at the end of Baki's fight with Mount Toba in the Underground Arena of Tokyo Dome. Yuujiro suddenly entering the arena, and all the people are surprised. Baki is furious at the sight of his father, because this is their first meeting in a very long time. He rushes at him impulsively, but Yuujiro effortlessly knocks out Baki. He is seen by Doppo Orochi, who also enters the arena. Doppo tells him that he still hasn't forgotten the scars, which are a reminder of their former struggle. Both fighters attack each other, but after a while they stops, and Doppo asks the chairman, Mitsunari Tokugawa, to set up a match between him and Yuujiro. Tokugawa happily agrees to this offer. Later that night, Strydum drives Yuujiro to a local boxing gym, where he starts a fight with the reigning boxing champion there. During that fight, Yuujiro admits that beating other people is better for him than having sex. Yuujiro effortlessly defeats the champion named Youichi Tatsumi and everyone at the gym, then leaves.
Later, one day Yuujiro meets with Izou Motobe on the street. Motobe tells him that he felt jealous when he found out that Doppo is going to fight against the Ogre. He also tells him that he want to settle personal business with Yuujiro. The Ogre decides to fight on the grass rather than concrete, and Motobe takes this as an act of fear by Yuujiro. He thinks that Yuujiro doesn't want to fight him on concrete, because Motobe is a master of using throwing techniques during the fight. Yuujiro states that he doesn't want anybody to interfere. Motobe shows that he has made great progress during his last years of training and Yuujiro praises him. Unfortunately, he has no chance to win against the Strongest Creature on Earth anyway. Eventually, Yuujiro knocks him out by throwing him to the ground, mockingly stating that Motobe is lucky because they didn't fight on concrete.
There is a manga chapter whose story has never been shown in the anime. It shows Yuujiro who beat up fighters from some local pro wrestling gym. Then he returns to his exclusive hotel, where he eats a big dinner, then he goes to bed and fantasizes about killing martial artists. Suddenly he instinctively senses someone standing near his door. When he comes to the door and grabs the handle, suddenly the iron door starts to be bombarded with a lot of blows from the other side. Surprised Yuujiro breaks down the door with a kick to see who it is, but it turns out there's nobody there. Most likely it was Kureha Shinogi, who was introduced to the series in the next chapter. In the beginning, Kureha hated all martial artists and liked to show them his superiority, so it could have been him, even though he had no major personal motive. Someone can also theorize that it was just Yuujiro's imagination. This is probably one of the strangest and most ambiguous chapters in the series.
Just before the start of the big clash, Yuujiro lies down and relaxes in the locker-room of the Underground Arena. When the fight begins, Doppo starts off the fight by jumping on top of Yuujiro and putting him in a full-body headlock. Yuujiro reacts by running and jumping off a wall, then slamming his back to the ground. Doppo dodges in time, and then delivers an axe kick at Yuujiro, which the Ogre dodges. Yuujiro tries to use Udonde technique against Doppo, while at the same time Doppo uses the Maeba Stance, which is also a defensive-based style. Yuujiro attacks first, giving Doppo the benefit of the attack, punching the Ogre 5 times in the chest. Yuujiro stands up, undamaged, and wildly punches at Doppo, while the karateka blocks. The fight continues, and Doppo uses Sangan, a fighting technique which allows the user to block all the opponents strikes by making the user's eyes mimic that of a chameleon's, therefore being able to see attacks from all directions, on Yuujiro. The Ogre is unable to get past this defense, and Doppo then proceeds to continually punch at Yuujiro. Doppo is successfully landing consecutive hits on him, until Baki arrives and is seen by the Ogre. Yuujiro becomes enraged at the sight of Baki, causing him to unleash his demon back. With Yuujiro's strength and speed now boosted, Doppo's punches no longer have effect on the Ogre. Yuujiro grabs Doppo's hand, and nearly rips one of his fingers off. Strydum makes the remark to Baki that Doppo's attacks are meant for humans, with the Ogre being something inhumanely powerful. Yuujiro then viciously attacks Doppo, with each hits cutting the karateka's body up. Atsushi Suedou, who is in the audience, jumps into the ring to try to prove that karate can win, attempting to prove Strydum's statement is wrong, only to be instantly knocked out by Yuujiro. Doppo attempts to try and pierce the Ogre's abs with his arms, only to be outdone by Yuujiro's reflexes, and have his eardrums ruptured. Doppo falls to the ground for a few seconds, with everyone watching thinking he is done. Doppo stands back up to keep fighting, but Yuujiro then suddenly rips out Doppo's right eye out of its socket. The Ogre finishes the match by delivering a punch directly to Doppo's heart, almost killing him.
Later, he comes to see his son's fight against Kureha Shinogi. At some point it seems that Baki has lost and then Kureha provokes Yuujiro to come down to the arena. Yuujiro accepts the offer and comes to him. But then Baki rises up and tells his father to not interfere. The Ogre looks at Baki's fighting position and guesses what technique his son will want to use. He wishes him good luck and leaves the ring. When Baki defeats Kureha with the Goutaijutsu strike, Yuujiro explains the technique to Strydum.
Maximum Tournament Saga
Yuujiro unexpectedly appears in the fighters' locker-room during the Maximum Tournament. Mitsunari Tokugawa asks him to not destroy his tournament, and Yuujiro says he only came to watch. Nevertheless, he wants his young companion Yuu Amanai to join the tournament. The Ogre breaks the spine of one of the competitors, Jagatta Sherman, to free up space for his companion. Amanai sees this brutal act and hits Yuujiro with his open hand in the face, telling him that he recognizes him as a fighter but hates his violence. At first it is unknown who Yuujiro's comrade is, but then it turns out he's a martial artist who met Yuujiro in USA when Amanai worked for the American government. The Ogre was impressed by the fighting style and philosophy of Amanai.
Most of the time, Yuujiro sits next to Tokugawa during the tournament and watches the fights. At some point he gets bored and goes outside. He meets a Muay Thai champion named Chamoan. Their fight is very short, and Yuujiro beats him with just one finger. When Chamoan is knocked out, Yuujiro smiles and says that this should satisfy him for a while.
During the tournament, Yuujiro meets Jack Hammer. When Jack wins his fight in the first round, Yuujiro goes into the arena to talk to him. Both fighters are almost starting to fight, but they're interrupted by jealous Baki. Yuujiro throws him aside with one blow so he won't stop them. After a while, Jack walks up to Yuujiro and tells him something that makes Yuujiro very happy. After a while, the Ogre announces that Jack has very right to fight him.
When Amanai finds that Doppo Orochi is already damaged enough to finish the fight, he starts asking Tokugawa and the audience to recognize him as the winner, because he does not want to use any more violence. Then Yuujiro enters and attacks Amanai with a blow of the edge of his hand, deforming Amanai's collarbone. Yujiro calls him a weakling and throws him to the fence of the arena. He wants to fight all current winners in the tournament, in exchange for disrupting the tournament. That's when Kureha comes and says that Yuujiro should fight the losers, because this tournament can't end like this. The Ogre beats them all without a problem. Then all the victors enter the arena and stars to provoke Yuujiro. However, suddenly Yuujiro is shot with a sleep bullets. It turns out that those shots were planned by Tokugawa and Baki to stop Yuujiro. He is taken away and moved to a closed room with a steel door, but after some time he wakes up, breaks down the door and leaves.
Before Baki's match with Kaiou Retsu, Yuujiro comes to talk to his son's opponent. He tells him he should be afraid of this fight. During the battle, Yuujiro watches his son's brutality and hopes that Retsu will awake the true "Hanma spirit" in Baki. However, ultimately Baki does not kill Retsu, even though he is very close. After the fight, Yuujiro meets Baki and tells him that he is disappointed because of his son's delicacy.
When the final fight between Baki and Jack almost takes place, Yuujiro meets Jack before the match begins. Jack tells him that when he wins the fight against Baki, he will come to defeat Yuujiro. During the final fight, Jack turns out to be son of Yuujiro and Diane Neil. After the fight, Yuujiro meets Jack again and is disappointed with his defeat and his destroyed body. He turns away from his son and tells him to leave, but Jack attacks him. A beaten fighter tries to bite Yuujiro, but fails. In return, the Ogre bites Jack brutally. Then he easily knocks out tired Jack, criticizes him for losing twice in one day and leaves.
Most Evil Death Row Convicts Saga
In this saga, Yuujiro is shown for the first time when he watches television, in which they talk about five convicts who have came to Tokyo. Yuujiro is in the middle of a small training session and at the same time smokes a cigarette, which he kicks out after a while, and then starts laughing at the police, who in his opinion will never understand how five prisoners arrived at the same time. Yuujiro refers to the phenomenon of synchronicity.
He hires Sikorsky to kidnap Kozue to make Baki fight him.
He encourages Baki and Kozue to have sex as many times as possible in order to make Baki stronger.
He brutalizes Yanagi for refusing to admit defeat.
Great Chinese Challenge Saga
Yuujiro decides to test Mahammad Alai Jr. and is pissed when Junior left the match unfinished. He fights Ryuu Kaiou and violently rips off his face. He later fight Kaiou Kaku, who manages to put up a good fight but the fight ends when Kaku suddenly dies of old-age. He met Kaku after he was revived and promised to fight again in a century.
Yuujiro is the strongest character in the series; he is recognized as "the Strongest Creature on Earth" with his strength being equated to, or perhaps even greater than an entire nation's modern military. Yuujiro, similar to his father, was able to defeat the American military forces by himself during the time of the Vietnam War; he was only 16 at the time. Some of Yuujiro's greatest feats of strength include: pushing back 100 riot police, completely stopping the tectonic activity of an earthquake by punching the ground, tapping craters in a concrete wall, easily knocking out a giant elephant not even tanks could damage, cutting glass with his fingers, and crushing a piece of coal to dust. Yuujiro's hits have even been likened to that of a nuclear impact, whole armies have used their best weapons to stop him, but to no effect. His body's muscles are so strong and durable to that he's able to do things like breaking katanas and knives just by gripping them, walking through walls of bulletproof-glass, and shaking an entire building by merely tensing his muscles; although it's also been implied that it was actually his body's aura. In fact, the strength of his finger flicks can be more than enough to defeat his opponent, as demonstrated in his short fight with Chamoan; he's also used this on a young Mohammad Alai Jr, managing to send the boy rolling back into the wall several feet behind him. When Yuujiro flexes his latissimus dorsi muscles, his back takes the shape of a demon's face, thus increasing his strength and combat abilities. Yujiro is constantly advancing his strength, becoming stronger with each person he defeats every day, essentially "devouring" them, as he himself tends to say, all the while his "demon back" is exposed.
Yuujiro is also very fast; he is shown to move at warp-like speeds, a level of speed that is imperceptible to other characters vision, almost as if he were teleporting. He is able to easily out-maneuver any character in the series in terms of pure speed; with characters who are at mid-top tier level being able to traverse across hundreds of miles in a matter of hours on foot. He can strike with enough velocity that can break the sound barrier and rip through the air, causing extremely intense gusts of wind. Yuujiro was shown to catch a 45lb arrow that required 200kgs of force to successfully project and caught before it could leave the bowstrings from 9ft away. He was able to easily move at bullet-like speeds when he was only 16.
Another indication of his incredible might would be his durability, Yuujiro being capable of taking a full power strike from literally anything or anyone on Earth without being damaged or even flinching whatsoever. He's also been shown plummeting out of the top of a 50 story skyscraper and getting up as though it were nothing, and he has never actually been hurt in any serious manner by any of the characters who've managed to land a hit on him in the series, the only exceptions are Kaiou Kaku (who was using the power of his own punches against him), Musashi Miyamoto (who just managed to leave a shallow cut on his neck), and Baki (who could only do so with the help of his demon back). However, even if they do cause some damage, Yuujiro´s pain tolerance is high enough that he can shrug off most attacks. Yuujiro has also been shown effortlessly overpowering the likes of Biscuit Oliva (who is strong enough to cause interference in the GPS's of all the cars on the planet with a punch to the ground) with just his fingers. His body is tough enough to withstand things like bullets (although he prefers to just dodge them), fire, lightning strikes, blades, diseases of any kind, cannonballs, and even missiles; with none of these being able to even penetrate his skin or injure him at all.
A genius fighter who is known to have mastered all forms of unarmed combat. His repertoire apparently includes all of the well known fighting styles (such as karate, boxing, taekwondo, juujutsu, wrestling, street-fighting, and so on) as well as some more esoteric ones (such as the Udonde art, an actual system used in the Motobu-ryuu of karate). Since the age of sixteen, he has been fighting on the battlefields using just his bare hands, when he fought against both American and Vietcong in the Vietnam War. Since then, it appears he has obtained respect from the American forces, even going so far as them declaring amity towards him with each new president. Yuujiro also has a complete and full understanding of the human body and its anatomy and essentially has complete medical knowledge on each organ and muscle and their respective function. It should be noted as well that, Yuujiro has the extraordinary ability to instantly learn and master a fighting style perfectly, upon the first time seeing it and even modify them to fit him better and directly seen other humans weakness just by looking on them.
In addition to all the techniques Yuujiro has demonstrated throughout the series that are listed above, he has made it clear on multiple occasions that he can master any technique instantaneously, simply upon seeing it used by someone else. However, he rarely uses the techniques of others for reasons other than to demonstrate his skill, and usually resorts to simple martial arts and exchanges of strength.
Although famous mostly for his strength and unmatched combat prowess, Yuujiro has proven many times to be of above average intelligence and knowledgeable about various topics, mostly related to combat and human body function, but also about the history, course of nature, foresight into the activities of others, and much more. Strydum once told Baki that Yuujiro's mental capacity is far stronger than any muscle on him, which is also a source of his power.
- Axe Kick – one of Yuujiro's most common move; used against Kaiou Kaku, for example.
- Roll Kick – used against Baki Hanma.
- Death Concentration – never seen him use it, but he confirmed it during his fight with Doppo.
- Udonde – used against Doppo Orochi.
- Finger-Grab – used once against Doppo Orochi.
- Demon Face – used on many occasions against opponents considered to be worthy challengers.
- Bite – used once against Jack Hanma.
- Crotch Kick – used once against Richard Filth.
- Front Neck-Lock – used once against Roland Istaz.

- The author of the manga stated that he created Yuujiro inspired by Matsutarou Sakaguchi, the main character of Notari Matsutarou manga series. His appearance at debut was based on Matt Dillon. However, his appearance in later parts of the manga appears to take after Paul Stanley.
- The "demon's back" idea came from the fact that the look of bodybuilders' backs reminded a human face to the author. At first, Yuujiro was supposed to have a dragon tattoo on his back.
- Yuujiro is a secret unlockable character in the video game Garouden Breakblow: Fist or Twist. His hair is blue rather than red; peculiarly, he can finish most fights in the game with just one move before the match even starts.
- Yuujiro seems to bear similarities with Street Fighter character, Akuma. Both have wild red hair, a fearsome complexion, and harbor strength that is considered superior to most of the fighters in their respective universes. They also provoke their younger rivals to become stronger by embracing their violent nature. On top of that, both seem to have dark personalities and frequently desire battle to test the limits of their own strength. The difference is that Akuma, though ruthless and callous, is less sadistic and arrogant than Yuujiro.
- No one, not even Baki himself, knows the exact limit of Yuujiro's strength.
- Yuujiro's testosterone levels are over 10 times of what a normal man can produce. It has been said that no mammal can produce testosterone levels as high as Yuujiro's.
