Black Lightning (Official Version)

Black Lightning is the highest level of Lightning Release.

To master nature transformation for lightning, one must learn to vibrate their chakra at the highest speed and volume to create as much lightning chakra as possible in an instant. Black Lightning stems from refining this process to the greatest extreme, increasing the frequency and intensity of the chakra vibrations to the maximum level possible. Once it reaches the pinnacle, the chakra transforms even further and turns pitch black.

In this state, the lightning chakra is closer to the true lightning of nature. It is capable of leaving flash burns and permanent nerve damage in its victim rather than temporarily paralysis and pain, moving at speeds surpassing ordinary lightning jutsu and even capable of producing thunder claps from the force of their passing.

Shinobi with exceptionally powerful chakra have been known to unconsciously create Black Lightning when performing Lightning Release but it usually happens once or twice in lifetime.

The art itself is a rare type of ninjutsu taught exclusively in Kumogakure. Starting from the Third Raikage's regime, the most promising students of each generations are given the chance to start learning Black Lightning. Those who succeed are given the right to bear a tattoo on their shoulder that says "Lightning" to mark their mastery, making it a well-known symbol of respect in Kumo.

Temporary Paralysis Jutsu

The Temporary Paralysis Jutsu is a D-rank ninjutsu which projects the user's chakra at the chosen target to physically restrain them, binding their bodies as if it was tied in invisible steel ropes. This freezes them in place to prevent any part of them from moving from the position they were in when the jutsu struck. And it can be performed on multiple targets at once to hold them all in place.

The strength of the paralysis depends on the user's level of skill, the number of targets it is being used on and the strength of its victims. As the name suggests, the paralysis is only temporary and a single casting can last no longer than a minute or so before the binding dissolves even at its maximum strength.

This jutsu is commonly learned by genin across all of the hidden villages. They typically use it on for paralyzing wild animals or criminals they encounter on their missions. But it does have its uses in combat to distract an opponent, briefly suppress them in preparation for a greater move or just for a stronger ninja to restrain a lesser one without hassle.

Attempting to cast the jutsu against an opponent too strong for it may not even delay them for a moment, doing nothing but wasting the user's own chakra.

Sai's Imitating Drawing

The Imitating Drawing Ninja Art was invented by Sai, former agent of Root.

Ever since he was a child, he had an incredible talent and interest in drawing and painting. After war tore apart his family and he became one of the orphans inducted into Konohagakure's Root Anbu, he continued to indulge that hobby throughout his ninja training. And he discovered that by infusing his chakra into the ink of his brush strokes he could make the drawings move across the paper as if alive.

Sai learned to use his ink as a medium such as wrapping himself in ink to hide his movements or composing a clone of himself entirely from ink.

With his moving drawings as inspiration, Sai created jutsu to truly bring his drawings to life. By infusing his ink with yang chakra and drawing living creatures, he can animate those drawings to grant them a three-dimensional shape that moves according to his will. They can keep to the same size of the original drawing and can grow several times larger if it suits his needs. And the more pictures he draws then the more of them can be brought to life. Once damaged, the drawings lose all cohesion and revert back to ink.

To ensure that he can always use his jutsu, he arms himself with plentiful supplies of ink, scrolls and brushes. And he practices his drawing so that he can draw his chosen images as fast as others can perform hand-seals for their own jutsu. Unfortunately his jutsu can only take effect for the relatively short period where his chakra remains in the ink which prevents him from simply keeping previously drawn images on hand.

The Super Beast Imitating Drawing animates the pictures of animals. The effects of the jutsu depend on which animals has chosen to draw with different creatures fulfilling different purposes. Lions can be used to attack enemies with fang and claws, birds can be used to survey the land from the sky or act as flying transportation to travel at high speed, mice can quietly move unnoticed for searches and relay anything they discover back to the caster and snakes can constrict their target and assassinate them with their bites.

Sai can draw any animal he knows of and the sheer versatility of the ability makes it Sai's signature jutsu for the many missions he has participated in. He can even combine his intelligent reports with his ink animals, allowing them to send themselves to his chosen target and turn back into written information.

The Super God Imitating Drawing animates the pictures of gods and buddhas. These are humanoid images rather than animal ones and are designed strictly for combat purposes. Divine beings that attack with their bare hands and immense strength, wield the bow with peerless accuracy, shield the wielder with their armored form or cut down their enemies with spear and sword. And their human shape gives them a greater connection to Sai himself, meaning that his own powerful emotions can enhance the strength of the beings he creates.

Amaterasu (Official Version)

This is an unquenchable black flame which is ignited within the caster's line of sight. It is the highest level of Fire Release with flames far hotter than what any other fire jutsu can accomplish, even with the skill and chakra of a master, such that it's likened to the heat of the sun itself.

Amaterasu will burn for seven days and nights or until its target has turned to ash. Its incredible heat and undying flames means that it is quite capable of burning or melting its way through practically any substance given time. Even fire itself can be burned out by the superior Amaterasu.

It cannot be extinguished through normal means and does not require fuel for it to burn so any volume of water will simply evaporate and even removing the oxygen would have no effect. But when it interacts with something flammable, the black flames are quick to spread so that even a small fire can turn into a firestorm that rages for days. And when a human is ignited, it only takes second for them to be completely enveloped in flames and rendered defenseless from the heat and pain.

Unlike ordinary fire jutsu, these black flames will ignite specifically at the target within the caster's sight without traveling the intervening space. They can continually create this fire anywhere within their line of sight even while shifting their gaze, allowing the flames to spread under their direction.

The only way for an enemy to overcome Amaterasu is to seal the flames away or absorb them. Otherwise they would need to intercept the flames with some kind of defence, move to avoid being set alight or remove the burning material but their flesh is caught alight. The caster, however, has the innate ability to extinguish Amaterasu to prevent it from going out of control.

Kagutsuchi (Official Version)

This is the ability to freely apply shape transformation to any and all flames within the caster's sight.

When they perform their regular fire ninjutsu, they can control these jutsu outside of their normal limitations to make them move, expand and change in a ways in all kinds of unpredictable ways that would be supremely difficult to manage otherwise. A fireball can turn into a mass of burning spikes, a flamethrower into a wall of flame or a fiery dragon into a swirling fire vortex. More importantly, the caster is not limited to their own jutsu as they can accomplish the same effects on the fire jutsu of their allies and enemies. Any incoming flames can be turned aside to protect them or turned back on their caster.

And while it can technically be used on the flames that weren't created by chakra, the same can be done with the application of fire chakra and makes it pointless to waste the use of Kagutsuchi on it.

But the true potential of the jutsu is realised when used in conjunction with Amaterasu as they directly complement one another as it allows the caster to go far beyond merely igniting and extinguishing the black flames.

This control can make the fire function like a solid substance to interact with other solids in ways that fire usually can't. It can be shaped into spikes to pierce through an object, into a blade to slice through them or even into arrows to strike from a distance. The flames can even be held in the caster's hand without burning them by preventing the flames and heat from affecting them.

Gold & Silver Brothers

Kinkaku and Ginkaku are the Gold and Silver Brothers, the greatest heroes and villains in the history of Kumogakure.

Truthfully, they are half-brothers born from two different mothers within a year of one another. Kinkaku was named for his mother's golden blonde hair while Ginkaku was named for the silver of his mother. Their father was a man of great vice descended from the Sage of Six Paths and both of his sons were inherited the strength of that ancestry. He trained them in the ways of shinobi until they were old enough to fend for themselves where they left to work as a two-man team.

Even when young, they possessed remarkable talent and power that allowed them to fight against enemies older and more experienced than themselves to succeed in their missions. More than often, they deliberately sought challenges were the odds were against them and still managed to come out on top.

One such challenge was to collect the Treasured Tools of the Sage of Six Paths that had been scattered around the world. They read the stories, sought the rumors and tracked down every single one regardless of how well protected they were or who wielded them. Then, to protect these tools from others, they sealed them within their bodies in such a way that only they would be able to summon them.

Thus it did not take long for them to became known as the Gold and Silver Brothers.

When Kumogakure was founded, the brothers had audacity to invite themselves into the organization. It was an unusual situation as only established ninja clans were joining the hidden villages at the beginning due to their strength and numbers. But their legendary reputation, proven skill and possession of the Treasured Tools were enough of the deal breaker that they were made welcome.

Within the hidden village's first year, they decided that their next greater challenge would be to fight and capture the Nine-Tailed Demon Fox with the Treasured Tools for Kumo. And they did find and fight the Tailed Beast but underestimated its power. Instead of capturing it, they were eaten alive and found themselves trapped within a belly of the beast.

None of their jutsu could overcome its immense, malignant energy and not even the Treasured Tools were of any use from inside it but they continued to fight for their survival. in the meanwhile, the brothers ate the fox's flesh and drink its blood to save themselves from dying of malnutrition or dehydration. Anyone else would have sickened and died from trying it but their heritage gave them a unique resistance, not only surviving but thriving on it.

By eating the chakra-made flesh, Kinkaku and Ginkaku assimilated that chakra into their own body. It altered them to mark their faces with whiskers, increased the quality and quantity of their chakra and, most importantly, granted them a permanent well of the Nine-Tails' chakra.

At any time, these pseudo-jinchuuriki could wrap themselves in a cloak of blood and chakra that turns them into a miniature version of the beast. They only possess six tails' worth of its chakra but are capable of incredible destruction, protected from many types of damage and retain their consciousness without the will of a Tailed Beast dominating their own.

When they returned to Kumo, having their failed mission but stronger than ever, this power was kept secret among the higher-ups. Whenever they used it on the battlefield they ensured that they killed everyone involved to prevent rumors of their ability from spreading. And the ones that did spread were simply considered exaggerated tales of their abilities.

Kinkaku and Ginkaku came to be known as Kumo's twin rays of light during the First Shinobi World War as they fought on the front lines to great effect. They even developed a following within their own hidden village as a number of ninja wished to train under their guidance and fight by their side. Each brother was formed a force of their own ninja - the Kinkaku Force and Ginkaku Force respectively - who went from battlefield to battlefield to wage war against Kumo's enemies.

But when Konoha and Kumo entered talks to form an alliance that could end the war, the brothers were against it. They had no interest in siding with their enemies and believed that they should destroy anyone who stood against them rather than seek peace through concession. In light of this, Kinkaku and Ginkaku attempted to launch a coup d'etat by killing the Second Hokage and Second Raikage during a diplomatic meeting.

The Kinkaku and Ginkaku Forces assaulted the meeting, killed the guards and were even able to murder the Second Raikage. However the Second Hokage was able to kill Ginkaku before escaping the ambush alive.

Enraged, Kinkaku swore vengeance against the Hokage for the death of his brother. Having failed their mission, he was forced to abandon Kumo knowing that he would be branded as a traitor for his actions. especially since the Treasured Tools sealed by Ginkaku were inaccessible even to his brothers, making the Amber Purifying Pot left in Kumo's possession as it was used to hold their tailed Beasts.

What was left of the brothers' followers unified under the name of the Kinkaku Force and went with him into exile. They continued to participate in the war for their own ends and killed everyone who was sent after them.

During the closing stages of the war later that year, the Kinkaku Force was able to confront the Second Hokage once more. Sacrificing himself to protect his team, Senju Tobirama battled them all single-handedly in a final battle that led to the death of everyone involved, including Kinkaku.

The Gold and Silver Brothers would be remembered as the greatest heroes who fell from grace to become the most reviled criminals in Kumo's history.

Explosive Tag (Official Version)

Explosive tags are a standard ninja tool that consist of a sealing formula applied to a slip of paper that is able to unleash an explosion.

The Explosion Sealing Method is a sealing formula which stores an individual's chakra in an pattern that causes it to react violently when unsealed. Once activated, the explosive tag starts to burn and then the chakra is released in an instantaneous burst of heat, flame and concussive force to produce an explosion. The more chakra sealed within the formula then the greater the force of explosion that is released.

An explosive tag can be activated in a number of ways. The standard method is for the user to channel their chakra into tag to unlock the seal. But it can also be set to detonate on a delay so that it explodes after a specified amount of time has passed, when in proximity to another person to hurt an enemy when they get too close or when they are moved or touched to set a sensitive trap.

If a tag explodes in close enough proximity to another tag then it will cause that one to react and explode as well. The more tags exploding together then the greater the range and scale of the explosion unleashed. Even just setting a tag on fire will cause it to react and explode.

Explosive tags can be combined with ninjutsu to add an extra dimension to using them in combat. Such as changing the coloring of the paper to camouflage it with its surroundings, manipulating the tags to attach themselves to the target, placing them in formation for a multi-directional explosion, and even combining them with other sealing formula for additional effects.

Most explosive tags are created by physically drawing the sealing formula and infusing the ink with chakra to empower it. The specifics of the explosion produced can be altered with changes to the sealing formula such as explosions with only heat or concussive force, focused in a specific direction or produce more light than force.

And charging these tags with nature transformed chakra can produce additional effects e.g. fire chakra that significantly increase the volume of flames produced by the explosion, water chakra can release a burst of scalding steam, earth chakra can fire shrapnel of razor sharp rocks etc.

Those who master the Explosion Sealing Method would be capable of creating the entire formula from their chakra alone. This is practically a required skill for Iwagakure's Explosion Corps who learn to create such explosion with a mere touch.

Spirit Transformation Jutsu

The Spirit Transformation Jutsu is an S-rank kinjutsu which detaches the caster's soul from their body and grants them conscious control over it, becoming a living ghost.

This transformed spirit is a ethereal copy of the caster that lacks substance and is not bound to the natural forces of the world. They are visible to the naked eye and can even communicate with the living but they cannot touch anything physical or be touched by it. And so they are able to travel by willing themselves to move, flying across great distances and through air, earth and water with great speed.

The purpose of the jutsu is for the caster to possess another person. If they have a specific target in mind then they can find that individual across any distance as their souls are drawn to one another.

By entering their target's body, they are able to seize control and use that body as their own to move and fight as they please. This makes it a useful tool for infiltrating enemy lines by possessing someone who belongs and using them as a tool to gather information or find a specific target.

More dangerously, they can kill the person they have possessed by making the existing soul collapse in itself. Once the original soul is broken, it vacates the body and passes on. However this is not an absolute killing method as it essentially relies on the caster pitting their chakra and soul against that of the individual they are possessing which can result in the death of either one of them, if not both.

There are, however, less harmful uses of this jutsu such as a communicating directly with another person's mind and soul over long distances or sharing their chakra with another person.

Ordinary, removing a soul from its original body results in the individual's death. But this jutsu tethers the soul to the body with an invisible bond of chakra to prevent them from being truly separated from one another, allowing the body to remain functionally alive but in a comatose state. This makes it vulnerable to harm as the caster has no awareness of their body's state or surroundings unless present which means that an enemy could attack it and thus kill them without resistance. To perform the jutsu safely, the caster needs allies they trust to watch over their body or a location where they are safe from harm.

The caster can only remain in this state for as long as they have the chakra to maintain it. The jutsu will constantly drain their chakra until they return to their original body to restore their stamina that they can replenish the chakra that they have lost. If they run out of chakra before returning to their body then they lose that tether and are left adrift until they pass on to the Pure Lands.

And the caster is not entirely invulnerable in their spirit form either. Though they are immune to physical attacks, the same does not apply to chakra-based attacks which are part spiritual energy. Their soul-body disperses if struck by an offensive jutsu and forces them to use their chakra to restore themselves so if it occurs too many times then the caster would die. Barrier ninjutsu are also capable of preventing them from entering or leaving a location in this form as the chakra forms in impassable wall for them.

It was one of the jutsu invented by the Second Hokage, Senju Tobirama, in his research of the nature of the soul as well as the Pure and Impure Lands. Years after his passing, it was learned by Kato Dan who used it to assassinate many of his nation's enemies until he was feared as the Spectre.

Tsukuyomi

Tsukuyomi is a genjutsu of the Mangekyo Sharingan.

It creates a dreamworld where the caster controls all time, space and substance. By manipulating all of the victim's senses, they can make them experience anything they desire by controlling the reality that they perceive. The illusion is only limited by the caster's imagination and knowledge as they can recreate the world as they know it or create their own world with its appearance and rules.

And their manipulation of one's sense of time means that they can extend the experience of the illusion far beyond the times it takes in the real world. While the genjutsu might only last a second in the real world, the victim could experience an illusion that lasts for hours or days entirely at the caster's mercy.

Like any other genjutsu, Tsukuyomi does not physically harm the victim in this sense that it inflicts wounds on their body. However its psychological damage can potentially kill one who lacks the mental fortitude to withstand it. Under the caster's control, they cannot rest or sleep regardless of how much the pain and exhaustion they feel so they are forced to experience every moment of the illusion.

At the very least, one would suffer migraines and mental exhaustion after the genjutsu. But more often than not, the victim's mind would be so thoroughly damage that they immediately lose consciousness and fall into a coma. Some might recovery after weeks or months, some could remain in a coma for the rest of their life and others might simply pass away as their mind breaks under the strain.

Tsukuyomi requires the caster to make eye contact with the target just like Genjutsu: Sharingan. The longer the genjutsu lasts and the more elaborate the illlusion then the more chakra it requires and the greater the strain it places on the caster, mentally and physically.

No ordinary subject is able to resist or escape the illusion. As they have lost all control over their body under its effect, they cannot disrupt their chakra flow or injure themselves to break it. Even if another individual realises that they are in an illusion and tries to break them free before it ends, it is powerful enough to resist such attempts regardless.

Only a Uchiha with the Sharingan would be able to resist its psychological effects or overcome the genjutsu itself depending on their strength. If this victim does overcome the jutsu, it has a painful backlash upon the caster and exhausts them more than a typical use of the jutsu.

Doing this one again.

Chakra Metal v2

A chakra metal is a specially made alloy which possess unique properties in reaction to the presence of chakra.

Ordinary substances only react to chakra being flowed through them in relatively minor ways. But by mixing together different metals with other metals or substances, carefully measuring their ratios and influencing that process with the manipulation of chakra, it is possible to create alloys that have all kinds of varied effects.

The most common type of chakra metal is one which perfectly conducts chakra without losing any in transmission or damaging the metal itself. While this would not be wasted on standard sets of kunai and shuriken, it is typically used for more customized weapons meant for long-lasting use such as the tanto provided to chuunin or the katana used by swordsmen.

Then there is that chakra metal which is able to absorb individual's chakra nature when it is channeled into them. Even after the wielder stops focusing their chakra into it, the metal will stay charged as the energy slowly dissipates over time. More importantly, it can even contain elemental chakra that has been transformed into a jutsu to allow the metal itself to produce the desired effect without the caster's direct input.

Other types have more esoteric effects such as becoming heavier and are used to provide small but effective training weights, becoming denser to resist physical force, absorbing chakra to consume incoming jutsu or repel chakra to act like armour.

 

[Knyght]

I'mma shelve for that for now then.

I did a load more of these research lists some time ago but haven't gotten around to using them yet:

Medical Ninjutsu (Research Notes)

• Kabuto healed a facial wound without a visible sign of chakra or hand-seals.
• Soldier Pills are used to increase your chakra. Among the genin, only Kiba and Chouji were shown to have any.
• Hinata had a healing salve which quickly heals injuries (though this was never used on someone without a pre-existing healing factor).
• The Dead Soul Jutsu is used to reanimate corpses.
• Kabuto was able to heal Hinata's internal damage and then knock Kiba unconscious with the Mystical Palm Jutsu.
• Tsunade was able to perfectly examine Orochimarus physical condition by mere proximity. It was believed that she would be able to heal his cursed arms.
• During the wars, Tsunade wanted to implement a system where each four-man cell included a medic-nin.
• It's impossible for medical ninjutsu to reform a destroyed organ.
• Tsunade can make a drug that can numb the body and temporarily interfere with their ability to create and use chakra for hours.
• Medical ninjutsu can be used to kill. Kabuto, as a medic himself, was able to recognize this.
• Chakra Scalpels are a medical ninjutsu which can be used to sever muscles and tendons without leaving an external injury. They can also sever arteries but this require too much control to achieve in battle. And they can cut off organs from the chakra network. These scalpels can be focused into fingertips instead of the entire hand and can cut through clothing or wood.
• Tsunade's Body Pathways Derangement confuses the electrical signals between the brain and body so trying to move one body part causes another to move instead.
• Kabuto carried a Blood Increasing Pill for after he slit his wrists. Apparently only medic-nin carry these pills.
• Kabuto's Yin Healing Wound Destruction heals the body before it is injured to rapidly recover.
• Healing injuries can cause steam to be released from the wound.
• Tsunade was able to heal the psychological damage caused by the Tsukuyomi to release Sasuke and Kakashi from their coma.
• She could perform a surgery which extracted bone fragments from vital nerves.
• After using the Three Coloured Pills, Chouji's body was wrapped in bandages with sealing formula. One nurse had a sealing formula on her hand and the other one has her hand pressed on another one.
• Konoha has a medical corps with a uniform.
• The Healing Resuscitation Regeneration Jutsu uses a giant sealing formula and can use hair as a medium to convert into different types of cells to heal an injury.
• Medical ninja need precise chakra control, a lot of medical expertise and the ability to apply it practically (and ambition?).
• Sakura practiced the Mystical Palm Jutsu on a fish to resuscitate it.
• The Delicate Illness Extraction Jutsu uses water as a medium to extract poison from the body. Any minute traces of the poison then need to be neutralized.
• Suna has its own medicinal herbs. Sakura used them to manufacture an antidote.
• Sakura was able to stop the bleeding of her wound and start healing it even with the weapon still inside her and without her hands.
• Chiyo started closing the wound while removing the sword.
• Aiming for vital spots can help hinder medic-nin from healing their patients.
• Kabuto can use the Mystical Palm Jutsu to heal from a distance.
• Sakura could heal burns over an entire body.
• Medical ninjutsu falls under Yin Release or Yang Release.
• Sakura learned how to create sleeping powders from Tsunade and poisons from Shizune.
• Medical ninja to learn use machines to analyzing a person's genetic profile.
• Tsunade can heal more than one person at once.
• Tsunade's medical ninja have three rules.
• Tsunade could share her chakra with another person.
• She restored Shikamaru to his normal condition after having his chakra drained to a life-threatening degree.
• Sakura used Chakra Scalpels to cut open Naruto's flesh and surrounded her other hand in chakra to manually pump his heart.

I've got a separate list for Creation Rebith.

 

[Knyght]

Where does one draw the line between medical ninjutsu and other jutsu that affect the body?

Medical Ninjutsu

Medical ninjutsu is a jutsu style which uses chakra to repair any harm the body has suffered by guiding, accelerating and enhancing the body's natural healing processes to restore their physical condition. As a type of Yang Release, it uses chakra mostly composed of physical energy to manipulate the body's cells and biological functions.

Fundamentally, it requires one to convert their chakra into a state that can be accepted by the recipient's chakra system without rejection. Otherwise channeling their chakra into their target would merely harm their body. Doing this allows them to restore the target's physical and mental energy so that they return to a physical state that can better mend their injuries and ailments. It is this requirement to transfer chakra without harm that separates medical ninjutsu from other jutsu that manipulate the body.

Then one sends chakra into a wounded area to make it restore itself by rapidly increasing its healing ability to repair the damaged cells of both external and internal injuries. The greater the injury then the more difficult and time-consuming it is to heal and not every wound can be healed. Scratches, bruises, burns and stab wounds are the easiest wounds to heal, followed by broken bones, torn muscles and severed tendons. The most difficult injuries are ones that are widespread across the body or damaged organs due to the time, effort and chakra required to restore them to a state without danger of death. And a significantly injured or destroyed organ is impossible to heal.

Beyond merely healing wounds, medical ninjutsu can also be used to treat drugs, poisons, sickness and disease by flushing out foreign substances, detoxify bodies and treat negative physical symptoms.

This ninja art is considered one of the most difficult as it requires precise chakra control, above average intelligence and advanced medical knowledge to effectively use it to heal without accidentally causing more harm. Those who specialize in medical ninjutsu - as well as other fields of medicine - are known as medic-nin.

And while it is known for being used to heal others, it works best the user's own body rather than that of another person as the chakra does not need to be changed to support a foreign chakra system and has direct access to the wounded area. In addition to healing one's own body, medic-nin typically learn jutsu that allows them to enhance their own bodies to better survive battle such as activating adrenal glands for surges of adrenaline, stimulating the nervous system to enhance their natural reflexes, triggering sweat glands and muscle to lower body temperature and other such manipulations.

Advancements in medicine and specialized training for medic-nin during the last century have led to the development of cooperative medical ninjutsu. By having training medic-nin work together on a patient, they are able to perform feats of healing that would be impossible for any of them individually such as regrowing lost flesh, healing internal organs or reattaching severed limbs. However these procedures can take hours to perform and are far more taxing than an ordinary healing session on everyone involved.

Fuuinjutsu is essential for this practice and is more closesly associated with medical ninjutsu than any other ninja art. As the primary role of fuuinjutsu is to seal out-of-control power it allows medical chakra to flow in a controlled state even when being provided by multiple users at once. Furthermore, fuuinjutsu can help the body remain in stable state when injured to avoid any further decline in health as well as sealing off afflicted body parts.

And just as an antidote can also a poison, medical ninjutsu can also a weapon in the right hands. The most obvious example of this are chakra scalpels which creates an extension of chakra from the user's hands. Often mistaken for wind release, this jutsu is actually composed of non-elemental yang charged chakra. Despite the name, a chakra scalpel is not actually sharp. Rather, the "blade" selectively severs the chemical bonds holding together any cells which it passes through. Chakra scalpels offer several advantages over conventional surgical instruments - Firstly, because the chakra scalpel does not actually cut living tissue, the lacerations it creates are much cleaner and finer than those created by even the sharpest wind blade, making them much easier to heal with other medical ninjutsu such as the mystical palm technique. And secondly, because the use decides what cells to sever and which to pass through harmlessly, a chakra scalpel can be used to operate on internal organs and tissue without causing unnecessary damage and while completely eliminating the risk of infection.

In addition, the very same properties that make the chakra such a versatile and powerful medical tool also make it a very effective weapon, although the chakra control and focus needed to wield them under such stressful conditions is quite high. In heated combat, even the greatest medical-nin won't be able to exert the precision needed to make fatal cuts, but it can still effectively cut muscle tissues and tendons, rendering the target immobile. No amount of body hardening or muscle training can protect someone from the effects of a chakra scalpel - if they are made of cells, they are vulnerable. Furthermore, reinforcing the hands with chakra is relatively easy for a ninja already skilled enough to fight with chakra scalpels, especially as they are already channeling chakra into their hands to use the jutsu in the first place, so a truly skilled medical ninja can not only use their hands for inflicting deadly wounds but also for blocking and deflecting swords, kunai and other ninja weapons.

And being able to manipulate bodily functions means that they can force their target's body to experience reactions that could hurt or kill them. One could cause their blood to clot within their veins, weaken the integrity of their bones, rewire their nervous systems or even cause cellular death throughout their body. While most medic-nin are best suited for support roles rather than battle, those with enough skill can be remarkably deadly enemies to face.

Most Famous Medics

Tsunade - The Slug Princess of Konoha's Sannin will undoubtedly be remembered as the greatest healer in history. Possessing a natural talent for chakra control, a keen intellect and a deep fascination with medicine, Tsunade was perfectly suited for the role of a medic-nin. She is a genius of medical ninjutsu who achieved greater contributions and achievements during her lifetime than anyone else had in centuries. This was especially true during the Shinobi World Wars where her medical skills were relied upon to save many lives.

In the Second Shinobi World War, Tsunade regularly fought on the front lines to protect her comrades. She healed their injuries both during and after battles to keep them alive and treated many different types of wounds, sicknesses and poisons used in the war. And as feared as she was for her superhuman strength, her ability to use medical ninjutsu in close combat could be just as dangerous. Then in Third Shinobi World War, she worked almost exclusively within Konoha rather than participating in battle. Yet her reputation as the greatest medic-nin only grows as she nevertheless developed new drugs, antidotes and medicine, trained more medic-nin, wrote advanced medical articles and create new medical ninjutsu up until the conclusion of the war.

She retired after the war as both a ninja and medic. She left Konoha with her chuunin apprentice, Shizune, and chose to travel the world having fulfilled her duties to her hidden village and nation. Even so Tsunade would go on to create her greatest medical ninjutsu yet, Creation Rebirth.

Haruno Sakura - She was the one of Tsunade's apprentice and proved herself to be the perfect successor as she learned all of her master's medical and combat skills. Her greatest achievement was completing the Strength of a Hundred Seal herself and using its chakra for the Creation Rebirth. While this was not so great as Tsunade inventing these jutsu, Sakura was able to master them before she was even twenty years old which made her a far greater healer than Tsunade herself at that age even if she didn't truly surpass her master until years later. Completing the seal in the Fourth Shinobi World War even allowed Sakura to become a more powerful fighter as she could use even more chakra to enhance her strikes without fearing that she would run out of chakra instead of holding back to carefully conserve it.

Yakushi Kabuto - Kabuto's own skill as a medic-nin is often overshadowed by his history as a spy and war criminal but he is considered by some to be the equal to Tsunade or her successor, Sakura. He spent most of his career using these skills almost entirely for the sake of self-preservation or preserving the victims of experimentation rather than simply healing the wounded, but that made him a more deadly fighter than most medics as he wielded those skills in battle.

One of his best medical ninjutsu was his self-invented Yin Healing Wound Destruction. It is named as such because it does not require yang chakra but regular chakra, meaning that it has far more mental energy than other medical ninjutsu. When Kabuto focuses his chakra into the area of the body that he anticipates a wound, it uses that mental energy to trick the cells into preparing for cellular repair before it has even been injured something that would negatively impact the body if tried with yang chakra. By building up a lot of chakra for this "pre-healing" it means that once the attack lands, it instantly starts to heal the wound even as the damage is being inflicted. This means that there is no delay in recovering from injury and grants an element of surprise as Kabuto counterattacks. Its only drawbacks are that it consumes far more chakra than an ordinary medical ninjutsu and if Kabuto fails to anticipate where the attack is going to hit then he suffers its full effect and wastes a lot of chakra for nothing.

Kabuto's medical skill was even pivotal to his later success as he delved into Orochimaru's research to assimilate the cells of other ninja, adopting their abilities for his own to make himself into a far more dangerous ninja than anyone expected.

Creation Rebirth/Strength of a Hundred Seal (Research Notes)

• Tsunade has a diamond shaped marking on her forehead to indicate her seal.
• Once unsealed with Yin Seal: Release, it spreads markings across her face.
• Creation Rebirth is a medical ninjutsu which regenerates organs and limbs rather than just healing at the cost of the wielder's lifespan. The seal on her forehead is from storing chakra for many years. It was developed after she left Konoha.
• The seal vanishes after performing Creation Rebirth.
• It causes a physical strain on her body.
• The seal reappeared once the battle was over.
• A side-effect of using Creation Rebirth causes her body to return to her original age. This is reverted once she rests.
• Tsunade has a jutsu where she transfers her chakra to Katsuyu to heal injuries and restore stamina remotely. She does not activate the seal to do this.
• To protect the villagers from Pains jutsu, Tsunade activated Creation Rebirth and transferred all of the chakra to them via Katsuyu. The effort put her in a coma for days/weeks.
• When she awoke, her seal had returned.
• Tsunade gorged herself to return her chakra levels back to normal.
• She used Creation Rebirth to heal the damage from the Heavenly Transfer Jutsu. She resealed her chakra before the marking disappeared and suffered no side-effects.
• The Strength of a Hundred Jutsu: Creation Rebirth spreads the seals markings across her entire body.
• It is a forbidden jutsu that applies only to her and the reason she is allowed to fight on the frontline according to her medical rules.
• Tsunade's ability to regenerate without hand-seals is comparable to Hashirama's innate healing.
• Tsunade is able to fight even when she sustained massive injuries to her torso.
• She can transfer her chakra into another person with her Strength of a Hundred Jutsu active.
• Tsunade was unable to regenerate her lower half after she was split in two.
• When Sakura's seal reached full capacity, the diamond marking appeared on her forehead.
• Her Cherry Blossom Impact grew severa times stronger as well.
• Sakura awakened the Strength of a Hundred Seal (named for the first time) by continuously amassing chakra with extremely delicate chakra control over three years. Shizune wasnt skilled enough to do the same.
• Sakura became able to remotely heal people through Katsuyu once she completed the Strength of a Hundred Seal.
• Katsuyu's healing power/speed is directly proportional to the strength of the Strength of a Hundred Seal. Tsunade retains her diamond marking even when aged, wounded and exhausted.
• Katsuyu can be remodelled into a healing area to restore anyone she touches.
• The markings of the Strength of a Hundred Seal can be spread to another person to transfer as much chakra as possible.

Added a section for Sakura to the previous article.

Creation Rebirth

This is a the pinnacle of all medical ninjutsu, created by the Slug Princess Tsunade.

Creation Rebirth uses a vast amount of chakra to stimulate all proteins in the body and accelerate cell division to rebuild them, allowing it to regenerate practically any body part when injured or destroyed. Flesh and muscle are regrown, bones knit back together, nerves are remade and blood is replenished. Even organs can be completely rebuilt and functioning when destroyed and amputated limbs are restored back to normal.

Unlike ordinary medical ninjutsu which can only repair cells, making cells regenerate is a far superior type of healing. One who wields this jutsu in battle is near impossible to kill. Tsunade was inspired by Senju Hashirama's unique ability to recover from injuries without needing hand-seals.

Creation Rebirth itself is intended as a short-lived jutsu which is activated to regenerate all of the wounds that Tsunade has suffered in battle and then stops once the body has been restored to its normal state.

However cells are only able to divide a finite number of times in one's lifespan so speeding up cell division allows them to survive immediate lethal injuries while shortening their life in the long term. Thus the more numerous and severe the injuries one suffers while using Creation Rebirth then the closer they ultimately come to death. Moreover, regenerating wounds so quickly strains the body which can render it weak and slow as soon as the jutsu ends, potentially leaving the user vulnerable.

Unfortunately, the amount of chakra required to activate such an extreme level of healing would exhaust almost anyone to death. To overcome this, Tsunade invented the Strength of a Hundred Seal.

Strength of a Hundred Seal

This S-rank fuuinjutsu is created by using extremely delicate chakra control to continuously amass chakra into a seal. One focuses a portion of their chakra into the shape of a sealing formula on their forehead at regular intervals to store it within the developing seal.

The greatest difficulty is when adding more chakra into the seal as they must prevent any chakra from leaking from it while carefully adding chakra to the sealing formula without disrupting it. The more chakra one tries to add at once then the harder it is to successfully seal, and the more chakra already contained in the seal means the greater the resistance as more is added so it becomes increasingly difficult as it reaches completion. At the same time, the longer the gap between intervals then the more chakra is lost from the seal in the meantime which extends the overall time it takes to complete it.

The sheer amount of chakra required for the seal to reach full capacity means that it takes years of effort and very few have the level of control required to succeed, even among medic-nin.

Once the seal reaches it full capacity, it becomes a diamond shaped marking engraved upon the user's forehead as it becomes permanent part of the bearer's chakra system. Just as Creation Rebirth was inspired by her grandfather's healing ability, the seal's shape was inspired by the marking her grandmother wore and was once a symbol of the Uzumaki Clan.

As the culmination of years of gathering chakra, it contains a truly vast amount that surpasses what even the most powerful shinobi could possibly produce at once. Its name symbolizes how it contains the chakra of a hundred versions of themselves.

Although this chakra is intended for Creation Rebirth, it is not restricted to this and can be used as fuel for any ninjutsu. One can be share the seal's chakra with another individual to provide them with chakra far beyond their normal limits or induce Creation Rebirth within their own body for a life-saving treatment.

Tsunade in particular learned to use the Strength of a Hundred Seal in conjunction with her slug summon, Katsuyu, to create the Immense Healing Network. By channeling her medical chakra through Katsuyu's clones, she is able to transfer her it into whoever they are attached to to heal their wounds and restore their stamina without being physically present.

Once all of the chakra within the seal has been exhausted, the seal vanishes from sight. It will then automatically draw in chakra from the bearer's body to replenish itself until its diamond marking reappears. However, unlike when the seal is first created, it does not need to be filled to its full capacity to be restored and the bearer can channel as much chakra into the seal as they desire without resistance.

Creation Rebirth: Strength of a Hundred Jutsu

This is the next stage of Creation Rebirth. By releasing the Strength of a Hundred Seal in its entirety and maintaining its presence, its immense chakra infuses every cell in her body to enact an ongoing regenerative effect which allows her to receive all kinds of injuries in battle without ever needing to slow down or stop as she immediately heals.

Moreover, this constant regeneration allows her to draw out as much of her superhuman strength as possible. She removes all physical restraints to unleash a hundred percent of her strength - magnified by her perfectly chakra control - to unleash more force than humanly. This comes at the cost of tearing her muscles and breaking her bones with every single blow but these wounds are instantly healed before they can debilitate her.

On the other hand, one's chakra and lifespan is used up at a far faster rate than merely using Creation Rebirth so it helps one fight at the highest peak but draws them ever closer to death.

Before finalizing the Medical Ninjutsu article, here is a revised version of an older article now with links. This will still be part of the greater article for kekkei genkai rather than a stand-alone.

Dead Bone Pulse

This kekkei genkai manipulates bone.

By controlling their osteoblasts and osteoclasts - cells which grow and break down bone tissue - one can control the growth and properties of their bones to freely manipulate and expand upon their own skeletal structure.

This allows them to grow any number of bones beneath their flesh in shapes and sizes that can be similar to their original bones or entirely different from their natural forms. And they can control the density of these bones to make them as hard as steel, raising their offensive and defensive capabilities as one.

These bones can protrude from any part of their body such as their hands, chest, shoulders and knees to stab or cut their enemies with any of their limbs. Able to rapidly extend and retract these bones without motion or hand-seals, one can attack in the most unpredictable ways. They can even separate these bones from the body entirely to wield them as a hand-held weapon and fashion them into crude tools, or even eject them from the body with enough force to become lethal projectiles. Alternatively, the bones can be grown specifically under the skin as a layer of armor that can deflect blades and blunt blows, protecting their internal organs from harm.

Masters of this kekkei genkai become inhuman monstrosities, surrounding themselves in armored plates, jagged spikes and disturbing weaponry. They can tear their enemies apart with every step while walking through incoming jutsu unimpeded.

And when combined with ninjutsu, one becomes able to create bones from surrounding materials rather than from their own body. They can create blades from the ground to pierce through enemies, cages to act as a shelter or a trap, shoot spikes from the terrain itself, blow up their own bones into high-speed shrapnel and even animate entire skeletons.

Upon awakening this kekkei genkai, the individual's bones harden to better resist breaking and any damage they do suffer heals instantly.Whenever they consciously grow and move bones, their bodies reacts by shifting and tearing their muscle fibers, blood vessels and flesh to allow passage and then restore the body to normal again (including replacing any missing bones) to prevent the body from killing itself with its own power. Even their pain receptors do not respond to these changes or damage inflicted to the bones to avoid debilitating the individual.

However these adaptations are only a reaction to the kekkei genkai itself and so the individual would not heal from damage caused by a foreign object or avoid experiencing pain from such injuries.

And it's dear companion piece.

Sakon and Ukon's Kekkei Genkai v3

Twin Cell Pulse

This kekkei genkai manipulates cells.

By controlling cellular fusion and fission, one can grow copies of their own body parts to provide them with additional limbs that they can control like any other. They can create hands and arms to grab objects, block attacks or punch an opponent, legs and feet to provide extra stability or kick an enemy, or even create another head that can perceive the world around them to cover one’s blind spots. These body parts can appear anywhere on the original body near instantly then withdraw just as quickly and there is little limit on how many body parts can be created, making them incredibly difficult to predict as they do not follow ordinary human movement.

However the proportions of these limbs have to be exactly the same as the original as they are literal copies. Because they are connected to the original body, any injury inflicted on them causes the individual to fully experience that pain themselves which does not have any lasting effect once the copied limb is removed but it can be distracting. And if a copied body part is severed from the main body, it cannot be reattached or controlled any further.

This cellular control grants those who possess this kekkei genkai with a type of accelerated healing by consciously splitting and fusing cells in response to the injuries they have suffered. This makes their recovery time far faster than ordinary humans and able to deal with injuries that others wouldn’t be able to without medical aid. However this feat does require focus and a significant portion of chakra which makes it unsuitable for combat situations so it is ideally only used after the battle has ended and cannot deal with extreme injuries.

And an unusual trait of this kekkei genkai is that it is often possessed by identical twins who instinctively use their abilities on each other from an early age. They willingly merge their bodies together with one of the twins becoming the main body while the other twin rests inside them, sharing one body and each other’s senses. Existing in this state becomes so natural that they spend practically their entire lives in the same body.

The advantages of this body sharing is that any battle against them is two-on-one as the twins utilize unsurpassed teamwork to overcome their enemies. By acting in unison, they can simultaneously attack and defend without needing to consciously focus on both actions as each twin acts independently both from the same body. The resting twin is able to separate their body parts from the active twin, allowing them to extend their hands to punch or grab or their feet to kick out or even their head to see from an entirely different angle. Merging can even aid in their self-healing ability as the synergy between their kekkei genkai helps accelerate the process further and the injured twin can hide within their sibling to avoid further damage.

However, twins often become too reliant on each other’s support which can be a significant disadvantage when they are separated. The active twin is more vulnerable to blind spots and has lower defences in combat, and the resting twin lacks the stamina and focus for protracted fights. At the same time, they are both unaccustomed to using their kekkei genkai to replicate their own body parts like the rest of their clan since they would ordinarily perform that role for one another which arguably makes them less dangerous when separated.

The ability to merge bodies is not actually limited to twins and can be performed by any two individuals who possess this kekkei genkai. But this is usually just a temporary measure to aid in combat to make them into one, stronger unit with a hidden trump card rather than a permanent state. There are no known cases where three or more individuals have successfully merged together, even among siblings.

When combining their abilities with ninjutsu, one can perform much greater feats such as creating entire clones of flesh directly from their body to act in concert, grow body parts from the surrounding environment rather than their own body or even forcibly merge with an enemy by breaking down their own body on a cellular level and enter their enemy's flesh, then they corrode the cells of their host to essentially consume them from within and recreate their own body. While these are rare and advanced skills that few possessed, it was enough to give this kekkei genkai a sinister reputation among those with such knowledge.

Summoning: Impure World Reincarnation (Research Notes)

• The Edo Tensei summons coffins that can act as a shield.
• The coffins contain reanimated shinobi.
• They possess their personality and are capable of speech but barely move beyond stepping out of their coffin.
• Orochimaru implanted a talisman directly into their head which didn’t appear damaged. He performed a hand-seal which restored their physical appearance by infusing them with life force.
• It sacrifices a living person to summon the soul of a dead person to turn them into a vessel. The talisman suppresses their personality to make them completely obedient.
• Orochimaru performs hand-seals to activate them which changes their eyes and black and white.
• They can perform ninjutsu and genjutsu.
• Any physical damage is quickly regenerated.
• Removing its soul is one of the ways to defeat it. Manipulating the soul also breaks the binding on their personality.
• After it is released from the summoned, the sacrifice returns. Even if they body had been totally destroyed.
• Several coffins can be summoned at once. They open and close as needed.
• Only three people have ever learned it: Tobirama, Orochimaru and Kabuto.

• Kabuto could strengthen the binding by increasing his personal power with Orochimaru’s chakra.
• It’s possible to resist the binding depending on the strength of the summoner and the summoned. Leaving their emotions weakens the binding.
• Total domination of the subject is shown when their eyes are a solid black and white. If they aren’t, they still possess awareness.
• It requires a certain amount of flesh of the target to revive them.
• Souls that don’t exist in the Pure Land cannot be summoned.
• Casting the jutsu creates a jutsu formula around the sacrifice.
• The sacrifice is engulfed in ash and dust to recreate the target. The talisman is needed to give them all of their power, including kekkei genkai.
• One way to stop the jutsu itself is for the caster to release it.
• Tobirama could not control as many as Kabuto.
• They can summon one another.

• They can be affected by poison and still have their internal organs.
• A powerful genjutsu can overwrite the binding.
• Nagato still suffered from weak legs after his revival.

• The purpose of the jutsu was to destroy everything and everyone without destroying the one who performed it. They always return.
• Tailed Beasts can be sealed inside them.
• The regeneration restores their clothing.
• Significant damage affects the entire body at once.
• Genjutsu can be used to force the caster to end the jutsu.
• They can experience pain.
• Izanagi and Izanami still affect the body
• Ending the jutsu causes the spirit to detach from the body.
• If the summon performs the jutsu themselves, they can free themselves from control.
• They can’t become the Ten Tails Jinchuuriki.
• Multiple sacrifices can be made simultaneously. The scroll isn’t needed.
• They can immediately be summoned with vitality and consciousness.
• Orochimaru doesn’t consider it a complicated jutsu.
• He could control them even without talismans
• The Hokages weren’t originally revived at their full power, this time they’re close it.
• Orochimaru could bind them in place and prevent them from using jutsu. He used Hashirama’s cells to boost his strength.
• They remain conscious regardless of the damage inflicted.
• Tobirama created a suicidal jutsu for his summons.
• Yin-Yang Release can stop its regeneration and kill the summons.
• Using Rinne Tensei on Edo Tensei gives them their existing body.
  Body parts missing from their original body are lost if revived. It creates fake versions of those body parts. Madara’s fake Rinnegan disappeared when revived.
