– Yuuichirou talking to Doppo Orochi.
Yuuichirou Hanma (範馬 勇一郎, Hanma Yūichirō) or Yuuichiro Hanma, is the father of Yuujirou Hanma and grandfather of Jack Hanma and Baki Hanma. He is the only other person aside from Yuujirou to defeat the USA on a small island in the Okinawa territory during WW2. He is also known for defeating 2,000 US soldiers using one technique.
Not much is known about Yuuichirou's personality, but it is noted from Mitsunari Tokugawa that he is the complete opposite of Yuujirou. This implies that he is possibly much kinder than him, as shown when he supports Baki in the fight against his father much to Yuujirou's anger. Also, Yuuichirou seems to be a quite carefree and calm person. This may be considered as one of the reasons why Yuujirou is being so harsh on Baki since he reminds Yuujirou of his own father.
There is evidence that shows he can be rather ruthless shown during the battle of Okinawa, when Yuuichirou fights and brutally beats the American soldiers in a completely gruesome way (twisting necks and broken bones, for example). However, it can be somehow justified since they are invading his home.
In the first chapter of Baki Gaiden: Kenjin it is revealed that Yuuichirou wasn't afraid to lose prizefights for money. Doppo Orochi confronts Yuuichirou about this, even saying he let his opponent trample on Japanese martial arts. Anyway, that makes him more benevolent than Yuujirou since he tries to earn the money legally. Yuuichirou is also glad that Doppo Orochi could understand his strength. This may indicate that even if he is humble, he still is proud of his immense strength.
Yuuichirou is a very large muscular man with exceptionally large broad shoulders noted by many not to be considered human. He has dark-colored hair that he ties in a simple ponytail. Like many men in the Hanma bloodline, he has the "demon" on his back muscles. Yuuichirou also has cauliflower ears due to his grappling battles.
On the battlefield, he was wearing no shirt or footwear but simply dons on a pair of simple drawstring shorts.
Yuuichirou is so strong that he was the only man before Yuujirou to take on the full military might of the US with only his bare hands and win. Major General James, the man in charge of the operation against Yuuichirou, requested the use of a nuclear bomb just to kill one man. His reason being is because they were unable to control Yuuichirou's rampage on a small island near Okinawa, when Yuuichirou annihilated a platoon of soldiers unscathed. Furthermore, the island he was on received heavy naval and aerial bombardment. Yuuichirou then proceeded to kill Major General James on board the Iowa Battleship, throwing him with such immense power, his corpse pierced through the wood of the ship. When Yuuichirou finally appeared before the more than 2000 crew who gathered around their commander's corpse. They all scampered away from him with great fear jumping from the ship towards the ocean, realizing that the person who stood before them was the man behind the death of all their fellow soldiers and their commander of the ship.
Baki Gaiden: Kenjin
Yuuichirou met a disappointed Doppo Orochi, who confronted him about throwing his match against the pro wrestler Rikigouzan. Orochi knew fully well that Yuuichirou is capable of blocking all incoming attacks and guessed that Yuuichirou took the attacks because he could and because his attacks were not even worthy of blocking. However, Orochi implied that Yuuichirou trampled the pride of Japanese martial arts by throwing his match against the pro wrestler. Yuuichirou, pleased by the fact that someone like Orochi knows his real capabilities, grabbed Orochi by his clothes. Orochi responded by nimbly getting out of the clothes Yuuichirou was grabbing on to, and kick him to the jaw, possibly breaking it. He then declared that he will set things straight with Rikigouzan, which would then also clear Yuuichirou's "loss" from the last match.
Strongest Father and Child Quarrel Saga
He appeared in the fight of Yuujirou Hanma against Baki Hanma as a spiritual apparition. He shows up near the end of Baki’s climactic fight against his father, with the sole purpose of cheering on his grandson. He also gives Yuujirou a hard time for having so much difficulty fighting against a kid less than half his age. His temporary visit is particularly jarring due to the series otherwise not containing any other explicitly supernatural elements. The interesting thing is that his presence seems to be so intimidating that even the inhumanly strong caveman Pickle can only tremble at the sight of him.
The true depths of Yuuichirou's strength is still currently unknown, but those who've come across him suggest he is inhumanly strong. As such shown in the battle of Okinawa to be the only other man in the world besides his son to single-handedly defeat the USA during WWII. It is unknown if Yuuichirou is stronger than Yuujirou, but it is stated that he was the only man he never defeated (however there is currently no evidence of them having fought at all in the past). This is most likely due to Yuuichirou's death which occurred most likely when Yuujirou was quite young. This is exemplified by his shocked and fearful expression when his father's spirit appeared to support Baki.
Yuuichirou is only known to use one technique to defeat two thousand US soldiers on the battleship Iowa. Many of the soldiers call this technique "dress" only for Yuujirou to correct it by stating the real technique was really called "guise". The user uses his opponent as a human weapon like a "nunchaku" surrounding himself in a spiritual image that looks like a dress. The power behind his throws is powerful enough that he is able to kill just about anyone he hits instantly. Its power is so immense, that when Major General James was thrown to the wood of the Iowa battleship, a wood durable enough to withstand direct attacks from big weapons, his corpse pierced through it. Furthermore, he can perform his variation of the technique so blindly fast that entire squadrons of soldiers can’t turn their guns fast enough to defend themselves against this truly gruesome move.
When Doppo Orochi started to fight him, he ends up possibly breaking Yuuichirou's jaw. This incident may hint that Yuuichirou might in fact be weaker than his son (Yuujirou endured Doppo's blows considerably more brutal than a kick to the jaw without being harmed). It could mean Yuuichirou simply let Doppo attack him as a way of testing Doppo's strength, given his glib and carefree behavior towards the latter before and after the fact. However, since it's hard to assess how strong Doppo was at this stage it's possible Yuuichirou is less durable than his son.
- The character is probably based on the real-life Japanese judoka and professional wrestler, Masahiko Kimura. To consider that Yuuichirou was based on Kimura, it is quite possible that Yuuichirou lost a prizefight on purpose to earn treatment fees for his ill wife.
