The Eight Demons (八魔,Hachima) are nine giant demons created by the Zenhōi kage. Each demon is said to have great strength that surpasses normal ninja. However, this immense strength is tempered due to their bestial nature, which restricts them from being intelligent enough to use it effectively. When the Tailed Beasts are sealed within humans, they are able to benefit from the knowledge of their hosts, giving them the ability to better utilise their powers. After being bound to a user, they are able to benefit from the knowledge of their hosts, giving them the ability to better utilise their powers.
