Yujiro siring Jack. A U.N agent in Vietnam tries to seduce Yujiro and lead him into a trap. His response? Threatening to kill her before raping her.
Open fractures are the least sort of horrible maiming you can expect to see in major fights of this series.
Want to be able to hit your enemies with supersonic punches and kicks? Steel yourself for reality: the sheer air friction will then be able to flay your entire arm down to the bone and even if you manage to connect with your enemy you'll break your hands and feet.
Consider for a second that your father is the most powerful creature on the planet, and he is grooming you to fight him. Then consider that since most fights with Yujiro end in him either killing a person or maiming them, the chance for parental leniency is low for you at best.
Also, consider both possible outcomes. Your father wins, you risk death or maiming. You win, your own father expects you to deliver the killing blow or maim him. Even when a third option is taken, there's an awful lot of damage ensuing.
Hey wanna throw a hit so hard that it breaks the sound barrier? How about punching the ground so hard it stops an earthquake?
Jack Hanma's steroids affecting his body at one point it breaks down on him and vomits green liquid and the steroids themselves turned a mild mannered guy into a unstoppable fighting machine who brutalizes his opponents.
While Motobe is in the middle of beating Yanagi, Yujiro out of nowhere just appears right behind him. What's even more terrifying is when Motobe faces him with just only his katana, Yujiro just breaks pieces of it as if it were Styrofoam to show how little of a threat it meant him.
Koushou Shinogi's technique involves literally ripping out the nerves of his opponents. Shudder. In his introduction, he's shown tearing out the optical nerves of a random person, blinding them — just for bumping into him in a hallway. Thankfully, doctors in the Baki universe are skilled enough to glue nerves back together, but still.
Yujiro's fight against Ryuu Kaioh ends with him tearing off the old man's face and tossing it at the horrified audience. Thankfully, this is one of the few instances in the series where the Gory Discretion Shot is used, so we aren't shown directly how Ryuu looks afterwards.
During Mohammad Ali Jr.'s fight against Jack Hammer, he makes a mistake of sticking out his tongue at Jack... who promptly punches him in the face, leading to Ali almost completely biting off half of his tongue, hanging on by just a tiny slice of flesh. And yes, it's shown in full detail.
One of Jun Guevara's techniques involves him sliding a few hairs into his opponent's ear, piercing through the eardrum... and wrapping the hair around their cochlea, slicing it to pieces. The only opponent to have met this fate on-page is gunned down by a prison guard soon afterwards, which could probably be considered a Mercy Kill: it's implied that he'd spend the rest of his life incapable of standing up, due to how important the cochlea is in maintaining balance.
Yujiro's early depiction in Grappler Baki implies that he regularly picks fights with random people, which end very badly for them. In particular, he's shown entering a boxing club, blocking the exit, and promptly beating the shit out of everyone inside. It's shown in a later flashback that he went as far as gouging out their eyes (though it's unknown if it's Yujiro's memory or just a fantasy). Imagine that you're just hanging out with fellow athletes, then Yujiro decides he wants to cripple you for life because he's bored, and since he's the strongest fighter on the planet, nobody will be able to stop him.
When Yujiro arrives at the Maximum Tournament with Yuu Amanai in tow, he removes one of the contestants (Jagatta Sherman, a Muay Thai fighter) to enter Amanai in his place. And by "remove", we mean he grabs the poor guy and folds his spine in half.
Gaia's Tunnel technique, which only appears in a side chapter featuring him killing an imitator. It involves him hiding in a seat and then cutting into the anus of his enemy then crawling out through their mouths. While this would normally sound like a goreydarkly comedic joke from an adult animated cartoon like Aqua Teen Hunger Force or South Park, it manages to be extremely horrifying due to the amount of detail it's drawn with. A reporter witnessing him using it understandably wets herself from fear and passes out.
Speaking of Gaia, his first real appearance counts as this, as after Baki has defeated the Chiba brothers, Nomura suddenly begins to cry and hiccup uncontrollably, causing his fellow soldiers to panic and beg Baki to run away for his own safety, and it should be noted that these mercenaries were completely willing to cannibalize Baki to survive without a second thought and even they thought that Gaia was too cruel for him. Nomura then gains a wide-eyed look on his face and begins to violently shake, before digging himself out of the hole he was buried in a manner that looks like he's being possessed by a ghost or a demon, and then he proceeds to make two horrifying faces one after the other before he proceeds to nearly defeat and kill Baki.
Speck is this all by himself, as he's a hulking giant of a man who looks frightening even when he isn't making one of the many horrifying expressions he regularly makes due to his wild-looking eyes as well as being a childish, disgusting psychopath with no redeeming qualities whatsoever. There's also how he's the most dangerous of the Five Most Evil Deathrow Inmates to be around, due to him being the only one to exercise no restraint whatsoever, as the rest have moments of being civil and non-violent, meaning that even if you aren't a superhuman fighter, you aren't safe around him, as he'll maul or even kill you if he thinks it's funny enough. There's also his VOICE in the original Japanese audio, as Chafurin gives him a high-pitched, slimy and lispy sounded voice with a constant perverted sounding tone that unnervingly puts the "child" in the "manchild" of his "psychopathic manchild" nature.
Oliva’s defeat at the hands of the second Nomi No Sukune. To recap: Olivia challenges Sukune to a Sumo match, threatening to arrest him for breaking Tokugawa’s punching bag without his permission. Oliva’s tachiai is easily absorbed and his attempt to pick up the sumo wrestler effortlessly defeated. So Oliva challenges Sukune to a “real fight”. Sukune obliges, breaking Oliva’s fist with a headbutt and picking him up by his ribs through his muscles and skin. Sukune warns him one last time to give up, but Oliva, refusing to listen, attempts to free himself by flexing all of his muscles at once, instantly shattering most of his ribs and breaking his spine. Sukune finishes by throwing him on his head, and after calling for an ambulance, casually notes that if he’d thrown Oliva on the ground instead of the wooden floor of Tokugawa’s mansion, he’d be dead. The last we see of him before the chapter ends is him lying on the floor, with narration noting he doesn’t even have the strength left to cry.
Yanagi's second prison escape from Tokyo Revenge is something straight out of a horror novel. After he manages to successfully convince the staff of the prison he was being held at that he was harmless after pretending to be reduced to a vegetative state after Yujiro maimed him, the staff of the prison decides to send an armed squadron of guards to escort him to a regular mental hospital, believing he's no longer a threat. But when one of them mockingly asks him if he can move, Yanagi slowly turns his head to look at him, before giving him a wild-eyed, derangedsmile after a brief pause that's made even worse by the transparent acrylic skin exposing his teeth as well as the muscle underneath his flesh, and then he proceeds to kill every, last, one of them in some unknown, highly violent method that leaves them all horribly and gruesomely mutilated, with the very first one lying face down, dead on the ground, with his brains literally blown out of his body, and all but one of them having their eyes gouged out, two of them getting their faces partially, and in the case of the latter, entirely ripped off. What makes it worse is that immediately after this, Yanagi straight up disappears, without leaving any evidence behind as to how he escaped.
Pickle the caveman. Think there’s enough terrifying fighters in modern day? Introducing straight out of the Jurassic era, a caveman so strong and ferocious he could pass for a Hanma ancestor! This evolutionary anomaly was found perfectly preserved in a salt rock formation of all things with a T.Rex. And from the looks of it, the dinosaur wasn’t preying on him, he was preying on it. The faces he makes range between a kid having fun to a feral beast barring its fangs. Whatever he is, he is most definitely not human. It’s theorized that he’s not just a Neanderthal but evolved from a different beast altogether. Then there’s his appetite. He’s not just a man but a proud warrior. As such he only eats creatures he sees as worthy opponents. So what do you suppose happens when the best martial artists in the series go up against him?
The HORRIFYING expression that Yujiro makes when he flexes all the muscles in his body to defend against Baki's Benda during their climatic battle, as he's drawn in a heavily detailed style with literally every vein bulging out from underneath his skin and his eyes being heavily bloodshot as well, and also having a barely restrained look of fury on his face. To top it all off, it also has him making eye contact with the reader making it look like he's staring directly at you.
