Bijuu List

The Tailed Beasts (尾獣, bijū) are giant demons that serve to drive the plot of the Naruto series. They are differentiated by the number of tails they have, with each possessing a number from one to nine. The Tailed Beasts are large, living forms of chakra, sometimes referred to as "Chakra Monsters" (チャクラのバケモノ, Chakura no Bakemono), giving them power that far outmatches most shinobi. 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 utilize their powers.

Only 2 demon hosts per village and you may not have a Kekki Genkai or 8 Gates if you are applying for a Jinchūriki character
