List of Jutsu Edit
Hiraishin no Jutsu - Flying Thunder God Technique Edit
Hiraishin no Jutsu is a ninjutsu technique utilized by the Fourth Hokage. The technique gave Yondaime his nickname "Konoha's Yellow Flash," due to his bright yellow hair and his ability to traverse great distances in the blink of an eye. A space-time jutsu like Kuchiyose, Yondaime first needs to mark his destination with a shiki (rite) first, he can then activate the jutsu to come to the mark. He can apply this to a weapon such as a kunai, and when thrown or used, he can instantly travel to it. He can also apply the mark to a touched area, such as his opponent or some other surrounding feature. No matter where the opponent goes, Yondaime can travel to the mark to kill them.

Edo Tensei - Resurrection to the Impure World Edit
Kuchiyose • Edo Tensei is a Ninjutsu technique which had been forbidden because of its dark nature. The technique involves the summoning of dead souls from the afterlife back into the real world. Normally Kuchiyose (summoning) involves the use of the caster's blood as compensation for summoning, Edo Tensei is different though. The ninja will first sacrifice a living person to provide the vessel that the dead soul will inhabit. The dead body will then be incased in ash and dirt to resemble the soul of the person that was resurrected. When the ninja wishes to recall the souls, a portal will open in the ground and the caskets holding the bodies will appear. When the caskets open the bodies will be grey and in a state of minor decay. At this point the dead souls are able to remember their past life, but they are at the command of the one who summoned them. One final act will fully wipe out their conscious and make them under the command of the one who summoned them. The ninja will place a fuda (charm/tag) of some form into the head of the body. This will then give vitality back to the body and make it a pure killing machine.
When a portion of the dead body is damaged, the ash and dust will merely return and fix the damaged body part. The only way currently known to stop the resurrected person, is to utilize the Shiki Fuujin technique and remove the soul from the body.

Raiton no Yoroi - Lightning Armor Edit
Raiton no Yoroi in a Ninjutsu technique which utilizes the Lightning Element. After surrounding and infusing his body with the Lightning Element, Raikage will greatly increase his speed, power and reaction time. This Lightning chakra will also act as a defensive shield, being able to greatly decrease the strength of incoming attacks, like a Chidori. The increase in speed will also grant him reflexes on par with Yondaime Hokage. These abilities will also be used in conjunction with his already powerful Taijutsu to create even deadlier attacks.
5 Lightning jutsus learned
Kirin - Kirin Edit
Kirin is a Ninjutsu technique developed by Uchiha Sasuke out of the original Chidori technique. Sasuke will first launch fireballs into the sky above using his Gouryuuka jutsu. These fireballs will warm the atmosphere and create a powerful rising air current, which in turn generates thunderclouds. Sasuke will then form Chidori and raise his arm to the heavens. This will allow him to channel the lightning down upon his target. Because he is merely channeling the naturally created lightning, he is able to utilize a power greater than what a ninja could create with their own elemental chakra. Because this is also natural lightning, it will travel more quickly than any ninja could dodge. Upon calling down the lightning, it will create a powerful impact with a large amount of destruction.
Chidori (and all varients)

Rasen Shuriken - Spiral Shuriken Edit
Fuuton • Rasen Shuriken is a Ninjutsu technique utilizing the Wind Element. Rasen Shuriken was developed by Uzumaki Naruto out of the original Fuuton • Rasengan. This spiraling Wind attack has only been seen in a half completed state. But even in this incomplete form, it has wrought massive destruction. With the aid of clones Naruto will form Rasengan and add the Wind Element. Though called "shuriken" the attack is not thrown. The trick name along with the aid of clones who act as a feint allow Naruto to get in close and strike his opponent. The attack itself can only be maintained in his hands for a few seconds time.
Rasen Shuriken is formed by enumerable miniscule small blades which slice into every cell of his target, severing the chakra circulatory channels connecting all the vital points on the body. Once it connects the highly dangerous attack will envelop the target in a massive sphere of destruction. The attack hits the opponent in such a way that it is even beyond the abilities of the Sharingan to copy. Due to its channel severing nature, the result on the body resembles a fast acting poison more than an outright attack. Unfortunately this same damage is done to Naruto's arm. For that reason Tsunade declared it forbidden.
Infuuin • Kai - Secret Mark Seal • Release Edit
Infuuin • Kai is a Fuuinjutsu technique developed by Tsunade that allows her to use the Souzou Saisei technique. Over a period of time, Tsunade will focus and build up chakra in the seal mark on her forehead. The release command will disperse the seal and allow the stored chakra to pump back into her body.

Shiki Fuujin - Corpse Spirit Sealing Method Edit
Shiki Fuujin is a Fuuinjutsu technique developed by the Fourth Hokage. A variation of this technique was used to seal the Kyuubi within Naruto. The technique was taught to the Third Hokage who later used it in battle. After calling forth the Shinigami (Death God) with the proper handseals, the user will hand over their soul in exchange for the Death God removing the soul from his target. The ultimate sacrificial jutsu, this technique can be used by a Kage Bunshin, but the Death God will still remove the original caster's soul.
With the jutsu activated, a spectral form of the caster will appear in front of the Death God. The Death God will push his arm through this spectral body, and the arm will extend from the chest of the real caster. This forces the caster to be close or grasping his target. The arm will reach out into the body of the target, and draw their soul from their body. If the Death God is unable to remove the whole soul because of the near death of the caster, it can remove it's knife and merely slice off a portion of the spectral form's soul to consume. This will render the targets corresponding body part dead and useless. The soul portion removed will then be sealed within the chest of the caster. Both the soul of the target and the caster will never pass into the afterlife. They will be condemned to suffer in the Death God's stomach for all eternity, locked in a hated combat, never to escape.
Senjutsu refers to a specialized field of jutsu that allows the user to sense and then gather the natural energy around a person. Senjutsu practitioners can then learn to draw the energy of nature inside of them blending it with their own chakra (created from spiritual and physical energy within the shinobi), adding a new dimension of power to the sage's chakra, resulting in the creation of "senjutsu chakra". This new chakra enables the user to enter an empowered state called Sage Mode, which can then drastically increase the strength of all ninjutsu, genjutsu, and taijutsu. A person who is able to use senjutsu is called a sage (仙人, sennin). It would seem that it stems from the toads of Mount Myōboku, as only Shima, Fukasaku, Jiraiya and Naruto have been seen using it.
