Fourth Hokage

Although as yet a largely unknown character to the series, Yondaime the fourth Hokage is widely known for his creation of powerful techniques such as Rasengan, a technique which solidifies chakra into the palm of the hand and swirling into confined instability until you release it on an object and a technique that Naruto uses himself. The move that gave him the nickname of yellow flash is Shunshin No Jutsu or “body flicker”. This uses Kunai which have had a seal drawn onto the handle, when he or someone else throws them they are used as a reference point on the battle field allowing him to flash to any point in the blink of an eye, they can also be given to friends or allies as a quick way to summon him if there should be need, by use of the seals on the kunai which allow him to know whenever one of them has been thrown
