Kurama first came into being in the waning days of the Sage of the Six Paths, who used his Creation of All Things ability to separate the Ten-Tails' chakra from its body and divide it into nine separate constructs that would come to be known as tailed beasts in order to ensure that it would never resurface after his death. Some time after being created, the Sage sat down with all the young tailed beasts and told them that they would always be together, even when separated, and that one day they would become one entity again with different names and forms than they did. Then, when the time came, they would know what true power is. Over the centuries, Kurama has gained a reputation as an age-old natural disaster, appearing suddenly out of nowhere to attack areas that have been breeding grounds for the darkest aspects of human nature. Kyuubi no Kitsune is responsible for attacking Konohagakure before being stopped by the Fourth Hokage, who gave his life to seal the fox into his son, Naruto Uzumaki, twelve years before the series' start.
Although Kurama is a kitsune with red-orange fur and red eyes, it possesses the upper-body structure of a human, complete with opposable thumbs on its clawed hands.
