Blocking Technique Absorption Seal

A highly advanced sealing technique that is capable of absorbing any chakra, regardless of any spacial or nature transformation, and dispersing it within one's body by spinning the chakra within one's body in the opposite direction. As a result, this technique can absorb any ninjutsu based technique, regardless of power, without harming the user.
This technique also has an offensive use. Should the user get close enough to grab the opponent, the barrier can absorb chakra right out of an individual's body, effectively draining them (similar to the Chakra Absorption Technique).

Blade of Wind

This jutsu creates a blade of wind. The blade is said to be impossible to block because of its intangible nature. Unlike the Sickle Weasel Technique, this jutsu requires no tool.

Black Secret Technique Machine One Shot

First the opponent must be trapped in the torso of Kuroari. After this is accomplished, Karasu separates into about eight components, each with a sharp blade. Kankurō guides the separate pieces into slits in Kuroari's torso, impaling the victim inside.

Binding Smoke Prison

Kigiri can manipulate his smoke to wrap around a target to keep them from moving.

Bee Honey Technique

Suzumebachi summons a large number of bees that swarm over and sting the opponent. Every time a bee is injured or destroyed, it releases sticky honey on the opponent, which is strong enough to immobilize them. This is particularly effective against opponents who rely on close range physical attacks, such as practitioners of the Gentle Fist.

Bee Bomb Technique

This jutsu summons bees with exploding tags attached to them. Once the bees come into contact with their target, the tags explode.

Bat Controlling: Ultrasonic Mind Waves

Once the Sound Ninja Rinji controls his bats, he commands them to produce high frequency ultrasonic waves that affect the mind of the opponent.
These bats (along with Shino's evolving bug strategy) have been the only effective counters to the Crystal Style. The ultrasound waves move at a frequency that allowed the crystal to breakdown at a molecular level. Allowed dispersion of crystal particles back into the air.

Bat Controlling

The Sound ninja Rinji has the special ability to produce ultrasonic waves and understand them. This way he can talk with bats, who use ultrasonic waves for communication. He is able to give them orders, like to search the area around him, and they seem to consider him a friend. He can use these bats for his attack Bat Controlling: Ultrasonic Mind Waves.

Barrier: Toad Gourd Prison

This technique summons a small, gourd-shaped toad, called a "Gourd Toad" (瓢箪蝦蟇, Hyōtan Gama), a unique species of toad indigenous to Myōbokuzan. This technique is used to capture and isolate a victim by dragging them into the toad's stomach. Isolated from the outside world by a barrier, the space inside the Gourd Toad's stomach is far larger than the surface size of the Gourd Toad itself.
The environment inside the toad's stomach is a cavernous chamber, which includes a lake of strong corrosive gastric acid that can dissolve anything that should happen to fall into it, along with shores around the acid lake, and stack formations sticking out of the acid lake. Once trapped inside, an opponent is cut off from any allies and susceptible to attack, and can then be easily defeated.

Barrier: Dome Method Formation

This barrier allows Jiraiya to detect the movements and position of any enemy that steps within it. He used it against Pain in an attempt to detect him after he had hidden inside a chameleon summon, which had blended into its surroundings.

Barrier Gate Five Seals Technique: Castle Closing Eight Gates

This jutsu requires a scroll on which a blueprint of a particular area should be. It will cause four giant gates to emerge north, east, south, and west of the desired area. Afterwards, the gates will form a protection barrier around the area. This barrier has a very high durability, anything that makes contact with it will immediately be engulfed in flames. The only way to pass through the barrier unharmed is with a special seal.

Barrier Encampment Method

An array of four exploding tags are jointly placed around the boundary of an area. If anyone or anything happens to walk through the boundary, the seals will instantly activate and explode, killing the imprisoned target.

Banshō Ten'in

Banshō Ten'in is a technique similar to Shinra Tensei in that it manipulates gravity at the users will, however instead of pushing objects away, it draws them close. It is unknown if it can be used in a similar scale as Shinra Tensei or if it has the same five second limit.

Ballistic Waterwheel

After the user swallows a great amount of water to make themselves into a human-sized ball, they tuck their limbs inside their clothes and use chakra to propel themselves into a powerful roll. The added water gives the user extra weight, causing more damage to the opponent and area. This is an excellent technique to use against Water Release users as it not only nullifies their attack but also turns it against them.

Asura Path

This body was very different from all other paths, being more like an android, as it had a number of body alterations. It was shown to have robotic inner workings, possessing six arms and a folded, serrated blade-like tail. It could fire one of its left forearms off as a long-range projectile, and could pull out his arms to reveal and fire a cluster of segmented missiles at its targets. It could quickly propel itself forward with a burst of chakra from its boots, and could protract multiple blades and a drill from one of its arms in battle. Also, it could open up the crown of its head to release a titanic shockwave that was capable of destroying numerous buildings at once. Its physical raw power was enough to rip Jiraiya's arm off, and then crush his throat with basic Taijutsu moves, as well as to throw Animal Path all the way into Konohagakure from the forests in its outskirts. All of these abilities befitted the "warring demon" name that the Asura Path held, whilst giving it a considerably higher degree of versatility than the other paths had (aside from the Deva Path).
Despite being used frequently and providing heavy firepower, the Asura Path was readily sacrificed to protect the even more powerful Deva Path, acting as a human shield against Kakashi's Lightning Cutter.

Assimilated Sand Waterfall Funeral

Very similar to Gaara's Sand Waterfall Funeral, with the exception of using rock powder instead of sand. After capturing a target with the Assimilated Sand Binding Coffin, Nagare causes the coffin to constrict and crushes the opponent to death.

Assimilated Sand Binding Coffin

This jutsu is a copy of Gaara's Sand Binding Coffin by Nagare, with the difference being rock powder instead of sand. However, Nagare needs to use Assimilate All Creation Technique before he can use this jutsu. The powder encloses the opponent and then crushes them, killing them.

Assimilated Rock Tank

This jutsu is a copied version of the Akimichi clan's Human Bullet Tank jutsu, the only difference being that the user uses the Assimilate All Creation Technique to fuse with a nearby rock and collect the necessary mass to perform it, instead of creating it themselves. Additionally, using rock powder makes it more damaging, since the resulting human ball is made of a much stronger and heavier material.

Assimilated Rock Blizzard

After performing the Assimilate All Creation Technique to fuse with an object, the user controls the rocks that make up his "body" and shoot the rocks at the target.

Assimilate All Creation Technique

With this technique, the user can take the properties of a nearby object. In the anime filler arc, Nagare took the properties of a rock and was then able to use his imitation of other technique, like Assimilated Rock Blizzard and Assimilated Sand Waterfall Funeral. He was also able to turn his skin to rock, entirely or partly, and could even survive being blown to bits by simply assembling himself.

Armor of Sticky Gold

By excreting his Sticky Gold from his pores, Kidōmaru can quickly create a temporary armor that is capable of blocking chakra once exposed to oxygen and even blocks the Hyūga clan's special taijutsu style, the Gentle Fist.

Armor of Sand

Using this jutsu, Gaara can cover himself in a compacted layer of sand, providing an additional defense should his Shield of Sand fail. Though quite effective, maintaining the armor requires a large amount of chakra and stamina. Furthermore, it is nowhere as resilient as the Shield of Sand, since it easily breaks away upon impact, meaning that the sole purpose of the armor is to absorb impact channeled unto Gaara's body during battle. Another weakness is the additional weight of the sand means a decrease of speed and mobility.

Arhat Fist

This style of combat focuses on simple physical attacks augmented with Jirōbō's incredible strength. Using simple palm strikes, shoulder thrusts, knee strikes, and punches, Jirōbō can easily defeat an opponent in one or two blows. The strength of his attacks is greatly increased when his cursed seal is active. For example, in his Cursed Seal Level One, he managed to strike back Chōji who was using his Spiked Human Bullet Tank with just one blow.

Moves
Rising Knee (昇膝, Shōshitsu): Jirōbō strikes his opponent with an upward thrust of his knee.
Thrusting Shoulder (突肩, Tokken): Jirōbō strikes his opponent with his shoulder.
Crumbling Palm (崩掌, Hōshō): Jirōbō strikes his opponent with a forward palm thrust.
Upwards Attacking Palm (昇撃掌, Shōgekishō): Jirōbō strikes his opponent with an upwards palm thrust.
Pressure Palm (圧掌, Asshō): Jirōbō strikes his opponent with an downwards palm thrust.
Rock Attack (岩撃, Gangeki): Jirōbō punches his opponent.

Antlion Ninja Arts: Ephemeral

The user creates four firefly-like chakra wings and fires out a powerful energy blast from them. Kagerō claims that this jutsu can be used only once in a lifetime, since it consumes so much chakra that the user is left in a near death state after performing it.

Animal Path

The Animal Path's main abilities revolved around summoning various animals and creatures to aid it in battle. Each creature served a different purpose in battle, much like every path of Pain was also different from the others. Each animal summon also shared Nagato's Rinnegan eyes and had various body piercings as well, suggesting that they too were under his control.
Tactics wise, the path's primary role in battle appeared to be overwhelming multiple opponents with its summons. In addition to that, both bodies used for this path were of a smaller stature than the other five, which, coupled with Pain's tendency to use his Asura Path to throw the second Animal Path in order to reach far off locations and infiltrate Konoha, as well as Pain's decision to first confront Jiraiya with the first Animal Path body, suggests that it acted as both a scout, as well as a way for Pain to move around the battlefield quickly through summons.
However, no blood sacrifice has been made when performing a Summoning Technique.

Animal Cursed Seal

To obtain this particular cursed seal, the chosen person is bitten by a snake to receive the instructions on how to form the potion that grants the user a seal, rather to have one directly given through a bite from Orochimaru like the rest of his cursed seals.
When the ingredients are formed into the potion and then ingested, the user will go into the first stage of the cursed seal and obtain enhanced abilities along with muscle growth and, in Mizuki's case with his tiger-like stripes, traits of an animal.
When the second level is reached, the user will attain the form of an animal along with the increasing strength and abilities, but decreased speed.
However, if the potion for the seal is consumed earlier than it is intended, then the results will backfire and the person's body will begin to destroy itself. In Mizuki's case, when the potion effects dissipated, he shriveled up into an angry and powerless old man, and would have died if not for Tsunade's medical skills. Regardless, Mizuki lost all of his powers and could never be a ninja ever again.

Amplification Summoning Technique

Upon being struck by a direct attack, the canine can divide into another identical beast and increase its power. The beast can then recombine if needed, with one body carrying the heads of however many additional beasts were created.

Amida's 1000-arm Death Embrace

This jutsu is activated when the user uses his left hand to make a half-ram and extending his right hand down with his palm parallel to the ground. Music starts playing as the user summons the spirit of Amida. The spirit is normally calm, angelic and looks peaceful. However, whenever the user gets angry, the spirit turns red and transforms into a somewhat demonic-looking creature. Amida then attacks the user's target with its 1000 spirit fists.
Asuma is able to use this technique. Although, Asuma's version isn't as effective as Chiriku's since the size of the spirit that envelops Asuma is much less.

Amaterasu

Amaterasu is the highest level Fire Release technique, as well as one of the most powerful ninjutsu in existence. It is said to represent the "Material World and Light" (物質界と光, Busshitsukai to Hikari), the antipode to Tsukuyomi, a genjutsu of similar power and a fellow Mangekyō Sharingan dōjutsu.
The jet-black flames of the Amaterasu, said to be as hot as the sun, ignite whatever the user looks upon. This can be either a specific point or anything in the user's field of vision. They're unavoidable as long as the user keeps their eyes focused on their target. The flames are extremely powerful, capable of burning through Jiraiya's Summoning: Toad Mouth Bind, which Jiraiya stated to be fire resistant. It can even smother regular flames easily. Amaterasu is said to burn for seven days and seven nights, and cannot be extinguished with water or any other normal methods. However, the flames burn fairly slowly, allowing anyone struck by Amaterasu an opportunity to remove whatever clothing or body parts have been caught ablaze. Use of the technique also puts a great deal of strain on the user, typically causing their eyes to bleed.
Amaterasu was originally unique to Itachi Uchiha, which he used with his right Mangekyō Sharingan. He is able to quell the flames to some extent. Prior to his death, Itachi implanted some of the black flames into Sasuke's eye to be used upon Madara Uchiha. Sasuke, after gaining his own Mangekyō Sharingan, is later able to use Amaterasu on his own. Sasuke's Amaterasu originates from his left eye, and Shī indicates he is more skilled with it than Itachi; he can put out the flames with greater ease and can even manipulate the flames themselves as part of the "Blaze" element.

Altering Terrain Diagram Scroll

Fuen uses a diagram of a location which can be changed when Fudō uses his Earth Release: Wheel of Fortune on the scroll. After the rock is summoned, Fuen can control the rock by changing her picture, allowing her to insert traps or create tracking mechanisms represented by red dots on her drawing.

All Directions Shuriken

After creating copies of himself with shadow clones, Naruto and his clones bombard the opponent with shuriken from every direction, making it hard to avoid. It is similar in effect to the Shuriken Shadow Clone Technique.

Adamantine Prison Wall

While in the form of the staff, Enma duplicates himself into a large quantity of staffs and forms a cage with them to protect Hiruzen Sarutobi. This jutsu was strong enough to defend even against Hashirama Senju's techniques. It is possible that this technique may be used to imprison a foe or enemy.
