Flying Thunder God Technique

The Flying Thunder God Technique is a technique which allows the user to transport themselves to a given marked location instantaneously.

Overview
To activate this technique, the user places a special seal or to mark an intended destination. After this is done, they can enter a dimensional void at will that instantaneously transports them to the location of the seal. The mark can be applied to almost any area through brief physical contact, including an opponent or some other surrounding feature. Because this technique is able to affect anything that is in contact with the user or somehow connected to their chakra, they can also use this technique to teleport other objects or people, such as when Minato used it to teleport Kurama out of Konohagakure, though the size of the object dictates the amount of chakra required. As Minato also noted, the marking formula never disappears from a marked target.

Tobirama Senju
As its original user, Tobirama's skills with this technique are quite impressive. As the general basis of the technique, Tobirama also uses a unique seal to mark his targets or desired location to teleport himself to within mere moments. He was fast enough to not only deflect Obito Uchiha's orb but to also return it to him before it could expand. He is also skilled enough to teleport not only himself, but other persons along with him over some distance.

Through his use of the Flying Thunder God Technique, Tobirama has also created derived techniques from it such as the Flying Thunder God Slash — a derived technique that compliments his kenjutsu prowess by incorporating this technique's instantaneous teleportation. With that technique, he was able to land a mortal wound on Izuna Uchiha. Another one of these derived techniques is the Instantaneous Swapping Flying Thunder God Technique which allows him to switch places at any point in time with another Flying Thunder God Technique user that he has marked. This technique's use was demonstrated with his fellow practitioner Minato Namikaze and together, they were able to land a surprise attack on the jinchūriki.

Minato Namikaze
Due to his exploits with this technique, Minato Namikaze gained the moniker of. Minato most commonly applied the formula in advance to his special kunai, which he would scatter all over the battlefield when a fight commenced, so that they could be teleported to at any time. Using such tactics, Konohagakure even proved victorious in a battle against Iwagakure during the Third Shinobi World War, despite already being vastly outnumbered. By having his subordinates toss his special kunai randomly into the enemy's lines, Minato used the technique to appear within their ranks, using his great speed to seemingly be in several places at once and wipe out entire squadrons one by one before they could even react.

This technique — combined with Minato's immense natural speed and reflexes made him the fastest ninja to ever live according to A. The technique is fast enough to even allow Minato to escape being warped away, despite having already been partially sucked in, and dodge A's top-speed attack. Minato could also incorporate the formula into other seals, such as that of his wife, allowing him to come immediately to her aid at any time. Minato also has the ability to send people to different markings simultaneously through direct contact with either himself or his chakra. Minato's shadow clone can use the technique to summon the original to its position.

Minato can also use the derived techniques of the Flying Thunder God Technique such as the Instantaneous Swapping Flying Thunder God Technique which he performed with Tobirama on the battlefield to devastating effects on Obito Uchiha.

Hokage Guard Platoon
Minato passed this technique on to his special guards: Genma Shiranui, Raidō Namiashi, and Iwashi Tatami. However, when they use this technique all three together are required to execute the technique. To do so, they form a circle with one another each performing the seal of confrontation so that their thumbs, middle, and index fingers are touching those of the other's. This allows them to transport both themselves and anything inside the confines of the ring to a marked destination. Since becoming the guards of the Fifth Hokage, they have marked Tsunade with the technique formula so that they can teleport to her side at any time. They used this method to teleport themselves, and Mei Terumī to the frontlines quite some distance away.

Trivia

 * Although it is often compared with the Body Flicker Technique, the speed and range of this technique are much greater. In principle, this technique is instead more similar to the Summoning Technique, as it revolves around the manipulation of the space–time continuum rather than accelerated movement. However, instead of bringing something to the user, it sends them somewhere. The technique was referred to as a on different occasions, though.
 * The name Hiraishin is also the phonic of the Japanese word 避雷針, which means "lightning rod". This may suggest the reasoning as to why the technique is restricted towards a seal, because lightning is attracted to lightning rods.
 * The technique can create smoke similar to a Summoning Technique, but that is not always the case.
 * Tobirama was the creator of the Flying Thunder God Technique.
