Naruto Uzumaki is the third jinchūriki of Kurama — the Nine-Tails. He is gifted with its enormous supply of chakra, to which Kakashi Hatake estimated it to be a hundred times greater than his own when its influence is not suppressed. It also gives Naruto accelerated healing (recovering from minor injuries within seconds and major injuries within a day). Also, depending on the amount of Kurama's chakra he's using, Naruto is given an increase in strength, speed, and his healing factor are pushed to such levels that he completely recovered from a Chidori through his chest in mere seconds with no signs of injury left. At times, he is also granted a nearly impenetrable, fox-shaped chakra shroud. Naruto had a unique access to Kurama's chakra, due to the seal that his father, Minato Namikaze, the Fourth Hokage, used on him. Minato stated that he sealed Kurama's Yang chakra within Naruto because he believed that Naruto would someday control its power to battle Tobi, which became a reality during the Fourth Shinobi World War.
