Quit actin' conceited, you lousy karate punk! You've gotten such a big head from fighting a gangster...

– Katsumi to himself during his fight with Hanayama.

Katsumi Orochi (愚地 克巳, Orochi Katsumi) is a fictional character from anime and manga series of Baki the Grappler. He is the adopted son of Doppo Orochi and Natsue Orochi. Katsumi is a 3rd dan Shinshinkai Karate prodigy and one of the strongest fighters from the series. His original surname is probably Katsuragi.

He is known as the "Lethal Weapon" (リーサルウェポン, Rīsaru Epon).


A 3rd dan, Doppo's adopted son and current prodigy of Shinshinkai karate. Katsumi is initially very cocky and reckless, but later matures into one of the strongest fighters in the Baki world before his battle with the prehistoric man Pickle. Nevertheless, Katsumi is an unbelievably durable person who is always seeking to better himself mentally and physically. After losing to Kaiou Retsu, he fights him to a draw in a rematch. Despite being nearly killed by Dorian, it doesn’t take long for him to seek a rematch with Dorian and return the favor of a near-death experience to the American. Also, he emerges from Doyle’s explosion burnt but ready to fight him and knock him out. Every fight for Katsumi is another chance to improve.

His encounter with Dorian shows that Katsumi also can be a vindictive and bloodthirsty person. After his brutal defeat in a fight with him, he attacked Dorian in the Tokugawa house. He kicked the bucket of gasoline that Dorian was holding all over him before setting him ablaze with his own lighter.

Katsumi and Doppo's relationship is not much like a typical father and son but more like friendly rivalry competing in the Maximum Tournament to win the champion belt for Natsue Orochi or proving who's Orochi style of Karate was superior. Nonetheless the two care about each other in their own way.

As the youngest Karate Master in the franchise, he is portrayed as exuding an air of confidence and consistently wears a smug smile, believing himself to be atop the martial arts world. This is evident when ignorantly he provokes Yuujiro Hanma during the in the beginning of the Pickle Wars Saga. After his fight with Pickle he matures and is often depicted as calm and composed.


Katsumi is a young man of large build standing just over six feet. He has brown hair in a flap top, thick eyebrows and gray eyes. Since the third anime series, his hair colour is simply black instead of dark brown as before. Also, his look and hairstyle often changes in the series. At first, he had his hair slicked back with a few short strands of hair falling down on his forehead. In the middle of the second series, the single strands of hair were no longer visible on his forehead. In the third manga series, Katsumi's hair was still the same length, but it was slightly raised up. Since Baki-Dou, his hair has been simply slicked back. Katsumi also used to wear various headgear, for example, a baseball cap or a scarf on his head.

Later, he loses his arm in battle. Pickle tears his arm off at the end of their first. The arm was useless after the Hitless Blow anyway. In Baki-Dou II, the arm of the deceased Kaiou Retsu was sewn to Katsumi's body through a special operation.


Baki the Grappler[]


Katsumi as a kid.

Katsumi worked in the circus when he was a 5-year-old boy. He was known for his extraordinary physical abilities and strength. His real father was a lion tamer in a circus that both him and his dad used to work in. Katsumi becomes the adopted son of Doppo and Natsue Orochi when his birth father was accidentally slaughtered by one of his circus lions. There is a scene in which Katsumi calms down an aggressive lion who escaped from his cage but then starts crying over what happened to his father. Doppo decides to adopt Katsumi, raise and trains the child as his own.

Maximum Tournament Saga[]

He is first introduced before the Maximum Tournament, where he is shown fighting some thugs on the street. He proceeds to beat them senseless, even going so far as to rip out one of the mens' two front teeth with just his fingers. Later it turns out that Katsumi beat them because Takeda, their leader, molested Inoue, a friend of the Shinshinkai dojo. Katsumi arrives at the Shinshinkai dojo because he was called by Doppo Orochi after Doppo's defeat with Yuujiro Hanma, wanting the dojo to be represented by the strongest possible people. The young karateka does some demonstrations of his strength in front of Shinshinkai students.

Later, he becomes one of the Maximum Tournament competitors. Even before the first fight begins, Katsumi is accosted in the locker-room by Kaiou Retsu, a Chinese fighter. Retsu tells him that Katsumi supposedly considers his karate to be a perfect fighting style. He demands from him to admit that his karate is weaker than the Chinese Kempo. Katsumi refuses with a smile on his face and offers him a fight to settle the conflict. However, they are stopped by Sergei Taktarov, who's gonna be a first opponent of Retsu in the tournament.

Later, when Kiyosumi Katou loses the fight against Yasha-Zaru Jr, Katsumi takes action to defeat the dangerous monkey. He uses a variety of powerful karate techniques and successfully manages to do a lot of damage to the ape. At some point, he intends to perform a final blow and kill Yasha-Zaru Jr, but then Baki Hanma stops him, prohibiting the murder of Yasha-Zaru Jr (Baki knew the monkey's father). Both competitors starts to fight, but Katou interrupts them. Katsumi and Baki decide to meet each other in the final of the tournament.

Katsumi during his fight with Roland Istaz.

He faces Roland Istaz, a wrestler known as the "Joint Maniac", in his first match. Before the fights begins, Doppo Orochi tells his son that this battle will show whether Katsumi is worthy to be called Doppo's successor, but the young karateka tells him to stop talking nonsense, thinking that this match will prove his superiority over Doppo. From the very beginning, Katsumi is very confident and starts playing with Istaz, running away from him all over the arena. The wrestler manages to dislocate some arm joints of Katsumi, but after a while he sets the joints in a place with one movement. Then the karateka rushes at Roland Istaz with powerful attacks. When he intends to perform the final blow against Istaz, who is lying on the ground, the wrestler unexpectedly turns out to be conscious and counterattacks with a fast armlock. Katsumi is released by lifting both of them out of the ground with only one hand, which causes that the armlock is no longer working. Eventually, the young Shinshinkai karateka brutally bombards his opponent with various attacks and knocks him out. After the fight, Katsumi meets Baki in the locker-room. Baki tells him that he doesn't like the way the karateka deals with things. After a while they start a short fight, but Kaoru Hanayama stops them, telling that Katsumi is his own prey.

Katsumi fighting Kaoru Hanayama.

Katsumi's next opponent is the young yakuza leader Kaoru Hanayama he had altercation with before in the warm-up room. Katsumi is very disrespectful to his opponent from the very beginning. The young karateka is unprepared for the strength and determination of Hanayama, and sustains extensive damage from Hanayama's attacks. At some point, Hanayama's strength overwhelms Katsumi so much that the young karate fighter starts running away from him in the arena, but it turns out that he is doing this to recover from his injuries and finally attacks with powerful karate techniques. Hanayama, however, does not give up and uses his famous Vice Grip and starts to perform powerful punches against karateka again. After feeling hopeless and questioning his ability to fight on, Kiyosumi Katou and Atsushi Suedou starts to perform the seiken punches beside an arena fence to restore Katsumi's will to continue fighting. Katsumi is then forced to use his special technique called the Mach Punch. With this move, Katsumi punches so fast that his fists break the sound barrier. Hanayama is defenseless against the unleashed Mach Fist, but he's still standing still, even though Katsumi urges him to surrender. Eventually, Hanayama turns his back to the karateka and takes the last Mach Punch to the tattoo on his back. Despite the victory, Katsumi sustained so much damage during the battle that he has to be carried out by his fellow Shinshinkai students, Kato and Suedo. The young karate master states that he has never had such a hard fight in his life and he has learned a lot from it.

Katsumi defeated by Kaiou Retsu.

Katsumi's final match in the tournament is against Chinese Kenpo practitioner named Kaiou Retsu, who easily defeated all his opponents in previous fights. Katsumi plans to attack with the Mach Punch at the beginning of the fight. He starts slowly approaching his opponent when Retsu unexpectedly attacks with an unusual technique called the Invisible Squash. Katsumi gets blinded and loses concentration, and after a while he sees Retsu standing next to him. He's trying to perform the Mach Punch, but the Chinese fighter counterattacks with the Sunkei technique. Due to Katsumi's extensive injuries and cocky attitude, he is defeated with one punch that sends him flying into the crowd. Although Katsumi manages to get back into the ring, he's no longer able to continue fighting and is barely standing because of the damage he's taken. Retsu then praises Katsumi on being able to get up after taking one of his best punches. However, the Chinese fighter also explains to Katsumi that his karate is incomplete and that he would never have had a chance against the Chinese Kempo. After a while, Katsumi falls to his knees, completely loses consciousness, and Retsu leaves the arena.

When Doppo Orochi loses the battle against Gouki Shibukawa, Katsumi learns that he will have to become the leader of the Shinshinkai dojo, because Doppo decides to start his training again and leave the dojo. In the manga, Katsumi is later seen in shock when he witnesses Baki perform the Mach Fist against Jack Hanma, and is also seen congratulating Baki after his tournament victory. In the anime, Katsumi doesn't see the final battle between Baki and Jack because he comes home with Doppo earlier. The last scene of the anime shows a conversation between Doppo and Katsumi about who they bet on as the winner of the tournament. Katsumi says he thinks that Baki is the winner.


Most Evil Death Row Convicts Saga[]

Katsumi and Retsu.

A short time after the Maximum Tournament, Katsumi has a formal rematch against Retsu Kaiou in the Shinshinkai building. This time their battle is very even, but after a while they decide to stop. The two fight to a draw, and Katsumi tells Shinshinkai's disciples that Retsu beat him in a tournament fight and his Chinese Kempo turned out to be stronger. Both seem to have a different approach to each other than before and have much more respect. Suddenly, they are interrupted by Dorian, a tall American and one of the five convicts who came to Tokyo in searching of "defeat". Katsumi gets nervous at the stranger because he forgets to take off his shoes when entering the dojo. Dorian proceeds to surprise rush at Katsumi, he attacks his eyes and eventually uses Katsumi's own karate belt to choke him. Katsumi retaliates and attacks with a powerful karate technique, but is hit in the throat with a splintered piece of wood thrown by Dorian. Katsumi's throat begins to bleed heavily and the young karate falls to the ground while Dorian escapes from the dojo after a while, trying to set fire to Kaiou Retsu, who wanted to stop him from escaping.

Katsumi fighting Dorian.

Dorian later crashes a meeting between Baki Hanma, Mitsunari Tokugawa, Doppo Orochi, Gouki Shibukawa, Kaoru Hanayama, and Kaiou Retsu. He comes with a bottle of gasoline and a lighter to set the room on fire, but is taken by surprise when Katsumi shows up and attacks him. Katsumi douses Dorian with gasoline and lights him on fire. Katsumi starts talking to his father about whether he did the right thing by using a dirty trick to the American. After a while it turns out that Dorian has not lost consciousness yet and Doppo intends to challenge the convict to a duel, but then Katsumi interrupts him, saying that he brought Kiyosumi Katou with him. It turns out that Katsumi started treating Katou as his new "senior" and came to conclusion that Katou's dirty way of fighting is more practical and better than Shinshinkai's way, but Doppo gets mad and tells his students that they made a mistake. At some point, the situation is interrupted, and Dorian escapes when he regurgitates a grenade and flees during the explosion.

Katsumi is seen later as Dorian is lured into an amusement park to fight the Shinshinkai Karate School in retaliation for nearly killing Kiyosumi Katou. He volunteers to fight Dorian, but is pushed aside by his adoptive father Orochi Doppo and becomes a spectator in the ensuing battle. After Dorian's defeat, he is not seen until the convict Hector Doyle infiltrates the Shinshinkai building and sets off an explosive that destroys the entire floor. Doyle is later brought back to the Shinshinkai building where Katsumi is waiting for him, although Katsumi now has burn marks all over his body with most of his hair singed away. Katsumi repeatedly attacks Doyle and renders him unconscious, but later praises Doyle after he was not afraid to take one of Katsumi's strongest attacks head-on. Katsumi arranges for Doyle to leave the country and teaches him some Shinshinkai Karate techniques. Before Katsumi departs, he gives Doyle his black belt.

Katsumi is briefly seen helping Baki track down where Sikorsky is holding Kozue Matsumoto. He watches as Baki fights Sikorsky and Biscuit Oliva.

Hanma Baki[]

Pickle Wars Saga[]

Katsumi during his battle with Pickle.

Katsumi is one of the fighters that breaks into Pickle's living area in an attempt to test himself against the prehistoric man. He unsuccessfully tries to attack Yuujiro, who humiliates him by telling him that "nobody wants to seriously fight with him". When Katsumi later hears about the defeat of Retsu Kaiou at the hands of Pickle, he tells his father that he is going to be the one to take Pickle down. He begins training hard, and even attacks Doppo to signify his newfound resolve. Retsu Kaiou later visits Katsumi while he is training, and offers to let him carry on the 4000 years of Chinese Kenpo. Katsumi refuses and makes it clear that it has to be Karate that is used to defeat Pickle. Retsu then trains with Katsumi and teaches him everything he knows, and Katsumi uses this to refine his own Karate (the 501st year of Karate). Kaiou Kaku shows up and offers to teach Katsumi a "perfect" technique, which Katsumi later crafts into a newly revised Mach Fist in which he attains ultimate relaxation and flexibility in his muscles when delivering the punches.

With his newfound strength and techniques, Katsumi arranges to fight Pickle in an arena where 55,000 Shinshinkai students have come to cheer him on. Katsumi's attacks are shown to be ineffective at first, but once Katsumi unleashes his improved Mach Fist, Pickle is brought to his knees for the first time in history. However, the aerial wall that Katsumi must break when performing the Mach Fist mangles Katsumi's hands and feet, rendering him unable to continue fighting. When Pickle prepares for his final attack, Katsumi unveils his ultimate Mach Fist technique and seemingly defeats the prehistoric warrior. The use of this final Mach Fist has a price: Katsumi's hand is reduced to bone and ligaments. Katsumi raises his arm in victory, but notices that Pickle was only sleeping and implores Pickle to finish him off. Pickle rips Katsumi's mangled arm from his body, which causes Katsumi to pass out from the blood loss. As a sign of respect, Pickle walks away and does not eat Katsumi, allowing him to be carried out on a stretcher. Katsumi is then seen recovering in a hospital having tea with Retsu Kaiou and discussing the merging of Chinese and Japanese martial arts. Baki steps in to visit and has the responsibility of fighting Pickle passed on to him by Katsumi. Katsumi is later shown practicing his new one arm techniques alone in the Shinshinkai building, until Baki shows up and has a conversation with him.

Strongest Father and Child Quarrel Saga[]

Katsumi is shown as one of the spectators watching Yuujiro Hanma fight Baki's fighting aura at the conclusion of the Hanma Baki manga series.


Katsumi is very strong and powerful fighter. He is taller and stronger than Western. With his karate, he was strong enough to defeat Yasha-Zaru Jr with a few techniques. He also defeated Kaoru Hanayama with his Mach Punch. He could easily defeat Hector Doyle in a fight. Katsumi has amazing durability and pain tolerance: withstanding Kaoru's punch and his Vice Grip, fighting Dorian after being poked in the eyes and being choked with his Karate belt and surviving after Dorian threw a broken board into his throat, fighting Doyle after being burn by mixed wheat flour and gun powder and defeating him. He managed to withstand the pain after his fist and leg being mangled by the sound barrier from using the Mach Punch and stayed conscious after using his Hitless Blow that tore all the tendons in his arm, skin and left only the bones. He even stayed alive after Pickle cut off his arm, causing massive blood loss. Despite all of that, he was once defeated by Retsu with a single punch, and he was defeated by Pickle.

During his fight against Kaoru Hanayama in the Maximum Tournament Saga, he uses a technique that was similar to the Shining Wizard move. Katsumi first strikes a kick on the yakuza boss stomach, then hits the Shining Wizard-like move on the jaw and finally, finishes it with a vicious elbow strike right on his face, with the force of it could have almost ruined Hanayama's face.
