Yujiro Hanma

Yuujirou is a fierce and arrogant man. He shows no mercy towards anybody, as he views mercy as a "weak" trait. Yuujirou 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.

Yuujirou is 37 years old, weighs 265 lbs.

Yuujirou 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 Yuuichirou), and his legs are extensionally long. Yuujirou has red wavy hair, thick black eyebrows, and red eyes (brown in Baki 2018 and 2020 anime series). Although Yuujirou 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. He almost always wears a type of Chinese-style shoes. 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.

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.

He is incredible intimidating having a menace aura that makes everyone around feel very frigthened. His mere presence is more than enough to make others be uncomfortable and nervous near to him. while normal people are scared of him, fighters and martial artists greatly respect Yuujirou due to his supernatural strength viewing him as the pinacle of power. He is considered by people as something more than a human and more like a creature or a force of nature that goes beyond human understanding. Yuujirou is feared to the point of USA granting him complete amnesty and even making a "contract" by the president that it has to be renewed every year.

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, Yuujirou was annoyed that he had gained unwanted fans and has referenced several young children asking for his autograph since the fight. Despite being wrathful, Yuujirou 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.
