2muchtext4me, it's faster if i say Yujiro's feats instead
Yujiro's main feats are knowing every martial that exists or existed, including Udonde, a fighting style only passed through the noble blood of the Ryukyu Royal Family that existed from the 15th to the 19th century (meaning he mastered it via hearing/reading about it). He also mastered Xiao Lee, a martial art that needs more than a century of everyday training to fully master, with a glance after seeing it being used once. His pressure points and knowledge of the human anatomy allow for him to instantly detect any physical weaknesses you may have and he can make you faint with a slight tap at the side of your heads. He dwarfs the entire verse in skill, including the likes of Doppo Orochi, Kaku Kaioh, and his son Baki Hanma. Doppo Orochi is a 10th Dan in Shinshikai Karate, and has repeated dozens of moves thousands of times for every day of his life for the last 50 years. He's also owner of the biggest Karate dojo on the entirety of Japan and knows techniques such as Sangan, that, much like Udonde, is an ancient technique that requires perfect control over the eyes' sinew to mimic the eye movements of a chameleon, amping your reaction speed and your field of view by a good lot. Orochi can also identify the difference between a "perfect" Seiken and a 99.99999999999...% accurate Seiken (Seiken being the straight punch, shot from the waist. A common move in Karate). His defensive stances, such as Mawashi Uke, allow him to defend even against fire using only his bare fists. Kaku Kaioh is a master of the Xiao Lee art, that requires for the user to completly remove their natural instincts and, like a leaf of grass in a blizzard, remain completly soft and without a trace of muscle tension even against people who can casually one-shot you. When a person punches you, even if they're millions of times stronger than yourself, your body will present 0 resistance to the impact and instead dissipate it in the shape of knokback and KE. Even the likes of Retsu Kaioh, another fighting genius and Kaku's apprentice, had to train very hard in order to even start understanding and utilizing a very incomplete version of it. Kaku also knows Chinese Kenpo moves that even Retsu, a Chinese Kenpo genius, never saw before. Hitless Blow is another move Kaku Kaioh taught to Katsumi, where you have to imagine your body like having thousands of joints. This imagination alone can make you deliver a whip-like attack that is thousands of times faster than your usual speed and as such works in people thousands of times stronger than yourself. Baki Hanma, just like Yujiro, can learn techniques extremely fast. He wastes no movements, dodging only with minimal movement, in a way that feels like you phased through him. He can perfectly predict the movements of black belts and the such of various martial arts, and exploit the 0.5 seconds of unconsciousness a person has while they're triggered but not conscious, from the time it takes for them to make an action until the time it takes for them to actually do it. And probably a bunch of other stuf i'm forgetting rn. Yujiro can perfectly see through the movements of Baki and other trained martial artists only by analyzing their stances. Yujiro is also way above Musashi Miyamoto, who is... well, Musashi Miyamoto. He should at least be comparable to his real-life counterpart. Musashi is able to intercept the brain signals of the opponent and as such predict his every move, what seems to be an ability derived from combat skill. Yujiro also defeated the USA in the Vietnam War while barehanded. The likes of Che Guevara can pull one of his own strand of hair, mold it into an appropriate shape, slip it inside the eardrums of the opponent, wrap it around their Cochlea, and push the strand of hair, crushing the Cochlea, what makes the opponent loose notion of balance. And he's not a remarkable character when it comes to skill. The likes of Kosho Shinogi can literally push your nerve cords out of your body and cut them, making selected part of your body completly useless, such as making you blind of one eye or making you lose control over one of your arms. And both these guys aren't really masters, just skilled folk.
These are starters, Baki has more than 800 chapters and obviously i don't recall everything perfectly. Specially for Baki, these aren't his best feats by far.
