Flying Thunder God Technique

The Flying Thunder God Technique was a technique created by Minato Namikaze, allowing the user to transport himself to another location in the blink of an eye. This technique was the reason behind his nickname, "Konoha's Yellow Flash" (木ノ葉の黄色い閃光, Konoha no Kiiroi Senkō).[1]
To activate this technique, the user needs a special seal or "technique formula" (術式, jutsu-shiki) to mark the destination. After this is done, the user enters a dimensional void that instantaneously transports himself to the location of the seal. The technique can create smoke, similar to a Summoning Technique, but that is not always the case. Minato applied the formula in advance to weapons such as kunai. By giving one such kunai to a person, he can immediately teleport to that person at any time. He can also apply the mark to a touched area, such as his opponent or some other surrounding feature.[2][3]
The technique is fast enough to even allow Minato to escape Tobi's Space–Time Migration, despite the latter already being in physical contact with him. Minato can also use this technique to teleport other objects, such as when he used it to teleport the Nine-Tailed Demon Fox out of Konohagakure, though the size of the object determines the amount of chakra required.[4]
It is because of this technique that Konohagakure came out victorious in a battle against Iwagakure during the Third Shinobi World War, despite already running short on manpower in the frontlines. After having his subordinates toss marked kunai randomly into the enemy ranks, Minato used the technique to appear within their ranks, using the great speed of this technique to seemingly appear to be in several places at once and wipe out entire squadrons one by one in moments before they could even react. This, combined with Minato's immense natural speed and reflexes makes this technique extremely deadly and according to A made Minato the fastest ninja to ever live.[5]
Minato passed the technique on to his special guards, Genma Shiranui, Raidō Namiashi and another shinobi, however all three are needed to perform the technique. To do so, they form a circle with one another by performing the seal of confrontation with each other with their thumbs, middle and index fingers touching. This allows them to transport anything within the confines of the ring. As they are now the guards of the Fifth Hokage, Tsunade has been marked with the technique formula.[6]
