Umori Kenshiro

Umori Kenshiro (大森健志郎, Ōmori Kenshirō), is a Super Rookie Pirate and Captain of the Reaper Pirates, the Shadow Leader and a founder of the Wung Family, and a member of the allied fleet known as the “Black Ops”. He's a former CP9 agent, marine and scientist for the Marine Science Unit. His research ranged from understanding the nature of Devil Fruits, human modifications, mass destruction weapons and biological weapons.

In the Underworld, his alias is "Yeomra, King of Tartaros". As Yeomra, he is known as an entity that will appear out of nowhere to pass judgement, either executing his victim or granting a favor. However, he expects something in return for his favors, in the near future.

Being involved in so many of the Government's secret experiments and operations for so many years, he poses a large threat given his knowledge of their inner workings. Kenshiro managed to amass a very powerful crew in just a few weeks after starting piracy, having people under him that can go toe to toe with powerful foes, which speaks volumes of his own strength.

After his involvement with the “Black Ops” and his fight against one of the Captains of the Xros Numerals, the largest allied fleet of the Xros Pirates, which ended up destroying an entire island part of the Yonko's territory, his bounty increased to 200,000,000, proving himself formidable enough to clash and push a powerful New World veteran like Skelton Red to his limits.

Appearance
Kenshiro is usually dressed in green clothes, wearing a green stripped hat and either a white or black cloak. He is always seen wearing his geta, japanese style clogs. Underneath his clothing, which he rarely reveals, is an incredibly sculpted and muscular body, built from decades of brutal training since childhood. He is usually seen carrying his katana on his hand, strapping it onto his waist on some occasions

Personality
Kenshiro is a very ambitious individual, always aiming for great achievements. He is not a coward, and he will face tough odds with a grin on his face. Some may describe him as being insane, as he will smile and not waver in difficult situations. He has no fear of death, which enables him to face though challenges and surpass his limits. He is a born leader and is very charismatic, something his superiors noticed while he worked under the government. He also seems to like to tease others quite a bit, as seen when he was teasing Dragon D. Dexter and questioning his capabilities.

Behind that charisma and nonchalant attitude, Umori Kenshiro is very manipulative, and is able to make people do what they want, even without their knowledge, mixing psychological tactics with his carefree attitude. At times, some even sense a dark aura at times around him, when he shows his more sinister, serious side. In battle, Kenshiro enjoys to play around, only showing his true power when necessary.



He seems to like joking around at times, as he will even tease his opponents while in the middle of a fight, and also pull pranks on others, as seen when he woke Eren Gyo up by placing a beetle on his face, claiming it was the best option at the moment. Kenshiro may be portrayed as cold, manipulative, sarcastic, carefree and ruthless, but Kenshiro is actually very attached to his crew, being the only people he apparently cares about, going as far as to decapitate someone who threatens his crew members. He also likes to keep himself informed, and he will always be up to date with the latest newspapers. He enjoys spicy food, even though they give him stomach problems.

History
Umori Kenshiro was born in Karakuri Island, located in the Grand Line. Being an orphan, he was raised in an orphanage, but he often escaped to science facilities. Because of this, he was exposed to highly advanced science since childhood and became quite proficient at them. He was recruited by the World Government at age 8 to receive training as a Cipher Pol agent.

Kenshiro rests on the island of Zen after escaping Marine HQ. Commodore Escaria Rita discovered that Kenshiro had been responsible for the murder of twelve marine soldiers. He killed them by injecting them with drugs without their knowledge. After she confronts him, he reveals that he had been waiting for a chance to leave everything behind, and proceeds to detonate five scientists, killing them and a few more marine soldiers.

After leaving Zen, Kenshiro arrives at Nassau, where he spends a week training with his recovered Meito sword, Junketsu, while waiting for Veno works to construct him a ship he had payed for. There, he finds his first mate, a woman named Catrina, and a few more crew members. He leaves with his new crew, and arrives at Dressrosa, where he stays for a while, recruiting four more members in the process. Now with a powerful crew, he contacts his old ally, Hydra Omelia, to execute a plan, to take over the Wung Family. He acquired the aid of Rander Vladious, and while Vladious dealt with the leader, Wung Juno, Kenshiro would ensure that he aided the Wung Family, in a ploy to act as the "saviors". Things don't go exactly as planned, and Kenshiro is forced to execute dozens of members of the security division, and later, to take down the infiltrators sent by the Several Pirates.

Nine years before current events, Kenshiro spars with his master, Bairen Guile, and later with a younger Hale Osiris. He is attacked by a sleepwalking Jirunga while he was taking a nap. The Giant assaults him with a barrage of attacks, which led the Marines present to believe Kenshiro had been killed. However, he stops Jirunga's final attack with one hand, while being bloody all over his face, and proceeds to knock the Marine Giant unconscious with one hit. Kenshiro comments about the Devil Fruit he recently acquired as a mission reward, but leaves everyone with doubts as he does not confirm if he ate it or not. He was also warned by Hale Osiris and Bairen to keep his “willpower” in check, as it would cause him serious trouble with his superiors. Later, Guile and Osiris discuss young Kenshiro's incredible Haki development, and the possibility of he possessing Haoshoku Haki.

Kenshiro is invited to join an assault on Xros territory, in order to take down the Yonko’s crew largest and strongest allied fleet, composed of veteran and notorious pirates, the Numerals. After a brief reunion and the formation of the “Black Ops”, the group composed of three Rookies, a Yonko commander and two Warlords, split up in order to take down the allied Captains and their forces. Kenshiro is joined by his crew mate Kire, and together engage in deadly combat against the Captain of the Mime Pirates, Numeral number III, the mysterious and powerful Skelton Red.

The battle is tough enough that Kenshiro is forced to reveal his hidden abilities, in order to prevent Red from rendezvousing with his allies. After the conflict, the already destroyed island of Megido was reduced to almost a barren

Abilities
Kenshiro is a former member of the CP9 unit and the Marines, and has been regarded as an extremely talented and powerful combatant with an insane potential and prodigious talent. He has been trained in hand to hand combat, Rokushiki and swordsmanship since he was 8 years old, training under Government and Marine instructors, some of the best they had to offer. Even after becoming a Marine scientist, in HQ he was required morning training almost every day, keeping him in top shape. He also trained under the Haki Development System since age 16, and was instructed by both Quarha Jaina and Bairen Guile. He has been regarded as an extremely talented Haki user

His strength has even been recognized by the likes of Vice Admiral Hale, when she insisted on him becoming an official Marine soldier, after sparring with him a couple of times. Also, at age 19, Guile even recommended that he should apply for CP-0, believing him to be a powerful addition to the group. He claimed that such a talented individual only appears once every few years. Bairen Guile also noted that Kenshiro has a very strong will, one of the strongest he had ever witnessed. This strong will was what allowed him to endure and become stronger after torturous years of training, and to completely nullify the Government’s brainwashing.

Being the captain of an incredibly powerful pirate crew already speaks volumes of his strength, commanding the respect and obedience of individuals that can go toe to toe with powerful individuals. It should also be noted that many of the members of his crew are Devil Fruit users, and have great mastery of their powers, which indicates that Kenshiro, without using his powers, which he prefers to have remain hidden, gained the total respect of his crewmates with his pure strength alone.

Kenshiro possesses incredible influence in the Underworld, having been one of the founding members of a successful Underworld organization. It should be noted that he dealt in illegal trades and constructed hidden laboratories where he conducted experiments, while being a part of the Marines.

Kenshiro and his comrade Kire face the Veteran Skelton Red, in which after a while testing their abilities, Kire takes a breather and leaves his Captain to face Red by himself for a while. During their incredible clash, Kenshiro proved more than capable of holding Red at bay and pushing him to the point of forcing Red to use his Devil Fruit Awakening, and even managed to land several cuts and bruises, although nothing serious. Even after Red used his awakening, Kenshiro held his ground, demonstrating masterful use of his Devil Fruit, Haki, and swordsmanship abilities.

Vice Admiral Hale Osiris considers Kenshiro such an enormous threat that she suggests a kill-on-sight order against him.

Kenshiro and Liam Grim attack a Marine ship in order to capture his former boss, Peg Nez. He demonstrates the usage of advanced Busoshoku Haki, when without even touching his target, he was able to send a Marine Captain flying almost out of the ship with a Haki enhanced palm strike.

Physical Strength
Kenshiro possesses immense superhuman physical strength. He is so powerful, he can stop a punch from an angry, sleepwalking giant with just one hand, and his kicks can destroy stone and steel, and easily crush a person's bones. He may not look imposing, but his days training as an assassin, and the daily training with the Marines, has given Kenshiro monstrous physical capabilities and condition for battle, and exceptionally tough endurance and superhuman durability.

Kenshiro very rarely strikes with punches, preferring to use palm strikes and chops when using his hands. Yet, these palm strikes carry unbelievable force behind them, creating a stream of air pressure than can knock someone back several meters and knock him out cold, usually reinforced by his Haki.

When serious, Kenshiro will not prolong a fight, as he usually does, aiming for fatal blows in order to finish fights quickly. Normally, he tends to go joke around and hold back unless interested in an opponent. However, he does enjoy a fight where he is forced to make a little more effort. He will keep his sword sheathed and retaliate with only the necessary strikes, but even while holding back, he rarely leaves an opening for his opponents, unless he does it deliberately in order to take advantage of it later.

As a fourteen year old, Kenshiro was capable of stopping a coup' in a country in the Grand Line. It should be noted that he fought for four days straight, taking down tanks, hundreds of soldiers and their reinforcements. He defeated an entire military force and their Revolutionary Army reinforcements by himself. At this point, he was already strong enough to kill trained soldiers in one blow, removing their heads with his bare hands, or striking their hearts, ensuring his kills. The successful completion of this extremely difficult mission was the reason he was awarded a Meito sword right after, and even Marine Vice Admirals and top Government officials began recognizing his name.

Swordsmanship
While already an incredibly powerful martial artist, Kenshiro is more comfortable using a sword in combination with his other techniques. He's been using a sword since before he began training as a CP-9 hopeful. At age 8, he began to receive formal swordsmanship training directly with some of the best swordsmen the World Government had to offer. At age 14, he became an official member of CP-9, and received a Meito sword after his first successful mission.

Umori Kenshiro carries his sword with him at all times. He is an extremely skilled swordsman, able to combine speed, agility and power masterfully. He can perform powerful attacks that cause devastating effects, creating craters in the area with just the shock wave of his sword attacks, as seen in his battle with Skelton Red.

Kenshiro is able to combine his swordsmanship with his Rokushiki, giving him extreme versatility in combat. This is possible because since he began training in Rokushiki, he also received sword training, so he is extremely comfortable using both styles interchangeably.

To this day, Kenshiro practices a training method known as the 3 day, 60 hour training routine. Where he isolates himself, and practices a single technique, for example a basic sword swing, for twenty hours straight, and has 4 hours to rest, eat, and do his basic needs, and repeats again until he completes 60 hours. He then may do it again with another technique. Another set of training was when he was required to perform several thousand "kata's" in a time span, with perfect form. This and several other intense training practices has granted Kenshiro with incredible mastery of his techniques and astounding training discipline.

By using Haki, Kenshiro can augment the force of his swordsmanship several times. He can also implement specific techniques by altering the form of his Haki. With his "Dragon Force", for example, the Haki coating his sword takes the form of a serpentine dragon, which he can shoot as if it were an air slash and can serve to overwhelm and capture his opponent. Another example is when he coats his sword in an even greater amount of Busoshoku Haki, extending his sword's length and reaching even his shoulder, and makes use of his "Sword of the Underworld" technique.

Iaijutsu

After leaving the CP-9, he began to train and master Iaijutsu techniques, also using it in combination with his Rokushiki techniques, in order to improve his swordsmanship. Iaijutsu is a swordsmanship technique where a person unsheathes his sword, cuts a target or blocks and attack, removes the blood from the sword if necessary and sheathes it again, all of this done fluently with amazing speed.

Kenshiro is capable of using this technique to block incoming attacks, slashing them faster than the blink of an eye. For offense, he uses it in combination with his fastest variant of Soru. He can do this without prior warning or preparation, just reappearing behind his target while his afterimage is still seen in his starting location, already having sliced his opponent. His strongest use of this technique requires a few seconds of concentration, and is basically capable to breaking almost anyone's defenses, seemingly unavoidable. Only the strongest of martial artists would be able to keep up and defend this powerful technique.

Stealth
Kenshiro, being trained in the art of assassination, has learned techniques to conceal his presence, even becoming "invisible" to a weaker user's Kenbunshoku. He can hide his presence for just a brief moment, aiding him in sneak attacks even when facing his opponent head on, which is supported by his immense speed. If Kenshiro proceeds to hide his presence even while being in front of someone, that person, even if not a martial artist, can "feel" his presence vanishing.

This is possible by controlling his breath and lowering his heartbeat to the point where his whole being becomes almost undetectable. Kenshiro combines this technique for daily use, with his Seimei Kikan, hiding his true strength and appearing as a normal person with no fighting capabilities, which takes his opponents off guard. Kenshiro not only can hide the presence of his body, but also his attacks, making it quite difficult for an opponent to "read" or predict his movements. This is a technique designed to combat efficient Kenbunshoku users.

Speed
Kenshiro possesses incredible leg strength and speed. He was able to spar with his master, Bairen Guile, and move so fast that the onlookers only felt the shock waves of their clashes, being unable to keep up with their fight. When activating his Soru he may sometimes appear to "teleport" around.

Kenshiro is able to attack and kill his opponents by moving at such speeds that they are terminated without ever realizing what had happened. Kenshiro can create afterimages that by all means and purposes, appear as completely solid clones of himself. By combining this with hiding his presence, it makes him possible to completely disappear from an opponents view, leaving a "solid" afterimage behind that disappears moments later.

During his fight with Red, Kenshiro demonstrated the ability to create hundreds of afterimages spanning a wide area, which aided in his misdirection attack, as they distracted Red from a large scale attack from above. He also proved capable of moving so blindingly fast his afterimage was still visible on his previous location when he was already striking Red from above.

Endurance and Durability
Kenshiro underwent brutal, torturous training since he was 8 years old, which resulted in him building a very powerful and resistant body, the result of a secret Government experiment. Even before this, he was surviving as an orphan in an island which is mostly covered by snow and cold year round, fighting against thugs and forest animals, which granted the young boy with a tough will. After he was recruited, Kenshiro's training was so tough, it was torture, as the World Government submitted Kenshiro and several hundred of other kids to gruesome trials and experiments as those performed by the Devil's Playground. He was submitted to days of training without rest and barely any food, under the toughest conditions, in order to push his body to peak levels. He was pushed to the point of vomiting blood and even almost dying multiple times. It was such the pain he underwent during his training that he attempted to assassinate his own instructors multiple times in rage.

His extreme training changed his physiology at the cellular level, the fibers in his muscles and even the tissues in his organs were greatly enhanced, developing an inhuman durability and tolerance to pain, abnormal levels of stamina and endurance. Kenshiro developed an extremely dense bone structure, many times denser than that of a regular human. Even he had to test himself as he thought he had some sort of exoskeleton, like those from modified humans.

At age 14, he had the capability to fight an entire nation's military comprised of thousands of soldiers, and kill hundreds in a span of four days, without barely having any rest. Another notable feat is that at age 19, Kenshiro tanked a barrage of attacks from a very angry giant, and casually stood up with only a bloody nose and forehead, something that made those present consider the option that if he was even human. It should be noted that he had just finished an intense sparing session with his master.

Not only did Kenshiro develop incredibly durable bones and tissue, he also developed a high tolerance to pain and electricity. One of the more frequent "training" methods for developing durability was exposing the trainees to extremely high voltages of electricity, in order to develop their resistance and pain tolerance. It would take a couple million of volts of electricity for Kenshiro to receive burn marks and to begin feeling slight pain. He later developed an immunity to most poisons by experimenting on himself and creating such antibodies.

Agility and Reflexes
He has incredible reaction time and reflexes, being able to keep up with an advanced Soru user, dodging deadly attacks prior to learning Kenbunshoku. If knocked back or down, he can instantly recover his balance and counterattack without wasting a single movement. Kenshiro can adapt to various surfaces and his surroundings, and use them to aid in his combat or to swiftly move around.

Sky Combat
With the use of Geppo and his speed at Soru, Kenshiro can easily fight without ever touching the ground in a battle. Moving quickly and attacking from various angles in the air, making even highly powerful opponents have a hard time with him, given his versatility and fighting arsenal. When he moved their fight to the air, Skelton Red recognized it would be difficult to fight Kenshiro while in midair.

Rokushiki
As a former Agent of the Chipher Pol 9, he was trained to become a master in unarmed combat, becoming a superhuman and a human weapon. He mastered all six styles and was considered a top agent, to the point where he was recommended to apply for CP-0, the strongest of the Cipher Pols. His Douriki is unknown. He claims he mastered the Six Styles equally, with no preference over any of them, also mastering the style's more advanced variations. Kenshiro has years of training with Rokushiki, as such, he is able to use the techniques and combine them in such a way that seems second nature..

Soru
While claiming he has no preference over techniques, two of Kenshiro's strongest attacks require the faster-than hypersonic speed of Soru. Soru is clearly one of the techniques he uses the most out of all. He can move so fast that he seems to vanish and reappear, even when his opponents are focused on him. He can create afterimages that appear solid, giving the illusion that he has created solid clones of himself. Against [[

Shigan
Kenshiro employs the use of Shigan quite frequently when he fights unarmed. He is shown to even be able to pierce through metal armor using just his fingers, without even activating his Haki, as shown in My Hunt, My Raid, where he pierced a Marine Captain's body with his bare hand, and even pulled out his heart.

Tekkai
Kenshiro rarely uses a full body Tekkai, instead opting to use the technique on certain parts at a time, giving him more use of it. He already has an incredibly durable and tough body, which this technique amplifies many times. Tekkai is essentially a muscle condensing technique, hardening his body to the point of imitating the toughness of iron. He may use the technique not only for defense, but combining it offensively with his already massive strength to increase it even further. He discovered this while training with Jaina, after both clashed their swords, he used Tekkai on his arms to try and overpower her, and later on his legs to maintain a solid stance. He can also use it at the last second of landing a kick or a palm strike, increasing the strength and heaviness of the attack even further.

Kamie
By making his body flexible, Kenshiro is able to effectively evade attacks. Combining this technique with Kenbunshoku Haki permits him to increase its effectiveness even further. He also uses this technique offensively, becoming able to bypass an opponents defenses using the same flexibility. Another use of this technique is when he combines it with Life Return, slimming down his body to increase speed, making his evasion even greater.

Rankyaku
Kenshiro mostly combines this technique with his swordsmanship, though he hasn't displayed this ability yet.

Geppo
One of his most used techniques, Kenshiro can combine this technique with Soru, moving at a high speed in the air that gives the perception that he is flying.

Rukuogan
Kenshiro hasn't revealed if he has the capacity to use this technique.

Life Return
Seimei Kikan is a technique Kenshiro learned that allows him to control his bodily functions. It was one of the first techniques he mastered, which helped him to develop the six styles even faster than others and with greater mastery. It also enables him to concentrate to focus on healing wounds faster, and digest the nutrients of the food he consumes at an accelerated rate. He uses it daily to conserve his energy and strength during his daily activities or training, as well as in fights, where he reserves his full strength and releases it when it is required. He can release Seimei Kikan in bursts, releasing his hidden strength for specific strikes or techniques and activating it again to conserve his strength, though it becomes quite tiring to switch in short lapses of time. This allows him to train or fight for days without tiring and actually recovering himself and his injuries.

Haki
Umori Kenshiro possesses all three types of Haki. At age 16, he was taught both Armament and Observation by undergoing the Haki Development System. After joining the Marines, at age 24, he had attained a 6th Dan (六段, Rokudan). He can use the Haki techniques of 6th Dan practitioners and lower.

Kenbunshoku
Kenshiro's level of precognition enables him to achieve nigh-perfect visions of the near future, depending on his level of concentration. He can also identify a person he has encountered before using Kenbunshoku, as seen when he sensed and recognized it was Commodore Rita when she entered the building he was in, even while he was several stories high. Even without the use of Haki, Kenshiro can sense if he's being followed or watched, as well as quickly pick up even a hint of malicious intent.

Circle of Perception: Kenshiro heightens his Kenbunshoku Haki even further, but on a much smaller radius. Inside this range, he can even count the droplets of rain in this state. He activates this in combat, and especially when using his Iaido techniques. When activating this in combat, his attacks are almost unavoidable. He displayed this technique when he arrived on the island of Megido.

Black Voice: Kenshiro developed a sonar technique, by touching the ground or a wall and activating his Kenbunshoku, he can further visualize the auras on a far greater surrounding area. He can effectively hear conversations through walls or at a distance.

Busoshoku
Being a Sixth Dan level practitioner, Kenshiro's mastery over Armament Haki is extremely high. He can regulate the output of Armament he employs, and also even be able to use it on his internal organs. Busoshoku: Bogyo, Busoshoku: Bugutai and Busoshoku: Seigyo are some of the techniques he can employ, using his armament internally and externally, providing a much stronger form of armament. He can also combine his Haki techniques with his Rokushiki and swordsmanship. He also learned how to extend his Armament on other physical objects, like tendrils on the ground.

Combat Techniques
Kagu-tsuchi Slash: Kenshiro fires a large and destructive air slash. It is one of his most used attacks.

Kagu-tsuchi Slash, Guillotine: Kenshiro does a 360 slash, cutting everything in a circumference area.

Kagu-tsuchi Slash, Assassination: Kenshiro surrounds his opponent using Soru, creating afterimages of himself, while launching air slashes with his sword, and shooting air needles at the air above of his opponent, which make it hard to detect, only after they start raining down on his opponent, because he keeps them occupied with high speed movement and slashes. This proved to work even against Skelton Red, as he managed to land a few slashes on the powerful veteran pirate.

Air Bullet: He applies the "Shigan" technique, using the tip of his sword or finger to shoot "air bullets" from a distance. By implementing Haki, is flying Shigan is several times more powerful and can travel at an even greater distance, capable of passing through several concrete walls.

Apophis Iaido: Kenshiro uses Soru to reach his opponent and strike multiple times, while reappearing behind him and already sheathing his sword. This was one of Kenshiro's most trained techniques. He can begin this technique while even casually walking, without prior warning.



Iaido, Izanami: Kenshiro envelops himself in a killing aura, sometimes paralyzing his opponent for a second and using Soru and Busoshoku: Bugutai to almost instantly deeply cut his opponent, and reappears behind his victim with his sword already sheathed, with his victim still looking at the previous location Kenshiro was in. This happens at such speeds, it is basically painless to his victim, being knocked out cold and in most cases, killed without realizing what had happened. With this technique, Kenshiro moves many times faster than in Apophis, Iaido, and only does one slash, combining all of his techniques, Haki and strength in this one attack. Kenshiro moves so fast and his strike is so powerful, that he can cut his opponent clean in half, even if coated in Armament Haki. This is one of Kenshiro's ultimate moves, as such he can only use it twice in battle so far, but the second time is a bit slower, although still faster than his other iaido technique. Kenshiro also developed a weaker version of this technique, which he can use without his sword, instead slashing with his hand. Kenshiro moves at such speed in this technique, that usually the ground is crushed at his starting point. Busoshoku: Bugutai greatly enhances Kenshiro's already insane speed and cutting power.

Equipment
Junketsu(Pure Blood): A Meito sword, he used to have and use the sword during his days on the CP9. He got rid of the sword after joining the marines, but recently acquired in on Nassau from an underworld broker. Being an O Wazamono grade sword, it is regarded as one of the finest made weapons in the world.

Genius Intellect
Kenshiro has been regarded as possessing a genius intellect, even from his days as an agent. As a child born in the famed science island, the same island the famous Dr. Vegapunk was born, he has been exposed to highly advanced technologies since birth. Even the Marines knew of the high intelligence of Kenshiro, as he often visited the science division before joining them.

Kenshiro is always planning many moves ahead. When he was confronted by Commodore Rita, he quickly knew what to do, having devised various plans for his escape when the time came. It was because of this, that he was able to do the things he did, like co-funding an Underworld Organization, and acquiring fame through his alias as a broker, even while being in the heavily guarded Marine HQ, and escape without much problems.

Even in his crew, he always has a few plans in motion in order for them to rise through the ranks,ea as seen in his schemes on Great Minds Think Alike.

When fighting an opponent, he combines his Kenbunshoku with his genius intellect to rapidly decipher his opponents patterns. He is able to notice subtle shifts in movement before an attack, and in most cases, he is able to see through attack patterns that even high level martial artists are unaware of themselves. He is even able to quickly develop effective countermeasures after seeing a Devil Fruit Ability or martial arts technique once, as he did against Red's powerful and versatile Mamu Mamu no Mi.

Master Scientist & Inventor:
As a former member of the Science Unit, Kenshiro is an inventor, engineer and scientist, having created a number of devices and techniques to aid the Government in battle. He worked in understanding the nature of Devil Fruits, on developing a greater understanding and use of the lineage factor, improving on human weapons and biological weapons.

After he became a scientist, it was known that he loved to experiment, even on himself. He experimented on himself and developed anti-bodies in order to become immune to most poisons. It is unknown what other experiments he did on himself.

Inventions
Flesh Bomb: Kenshiro has developed biological bombs that can be implanted into the bodies of people by pill or injection. By using a remote detonator he can set off the bombs that are inside the victim's body, causing a massive explosion that may kill nearby people. He demonstrated this bomb's functionality in A Not So Fresh Start.

Devil Fruit Sensor: A work in progress, Umori Kenshiro aims to create a Devil Fruit sensor device which will detect Devil Fruits or Devil Fruit users.

Nervous system Drug: A powerful drug which makes the nervous system of a person go array, in a couple of seconds rendering the victim incapable of performing anything.

Thought Inhibitor Drug: Kenshiro concocts a special drug which can stop thought processes from occurring within the brain.

Superhuman drug: It makes the user reach peak physical form for a couple of minutes, later completely destroying the user's muscles, ligaments and tendons.

Red Laser: Similar to the Pacifista's laser beams, he helped develop another type of laser, which takes on a reddish color. It's destructive capabilities is greater.

Exoskeleton Augmentation: Kenshiro developed an exoskeleton, similar to those the Germa children are born with around their skeletons, except they are worn externally and are more durable.

Cyborg Creation: Kenshiro learned the mechanics of creating robotic bodies and installing artificial intelligence, which he used to aid in the government's new weapons and cyborg improvements.

Warmongers: Weaponized cyborgs developed by Kenshiro, originally for the purpose of serving the Government.
