Bijuu (Earth-2356)

The Bijuu, also known as tailed beasts and sometimes referred to as "Force monsters", are the nine titanic sentient forms of midi-chlorians created by the Sage of Six Paths out of the midi-chlorians from the Ten-Tails. They are differentiated by the number of tails they have, ranging from one to nine. Individuals who became recipients to the Bijuu are known as Jinchuriki.
