The Legendary Tailed Beasts (尾獣, Bijū) are a group from the Naruto series created by Masashi Kishimoto. The series first began serialization in Shueisha's Weekly Shonen Jump in November 1999. It first appeared in NarutoVolume 1, CH. 1 "Uzumaki Naruto".
The Tailed-Beasts are demonic monsters that possess vast chakra, immense physical might, and unbelievable destructive power.They were all derived from the Ten-Tailed Beast. Thousands of years ago, the Ten-Tails tormented the world with its vast power. The world was saved from the Ten-Tails' wrath by the Sage of Six Paths; who sealed the Ten-Tails within his own body to contain it. However, this was only a temporary solution. Upon his death, the Ten-Tails would be released. The Sage of Sixth Paths used the Creation of All Things (万物創造, Banbutsu Sōzō) ninjutsu to separate the Ten-Tails' power into nine separate beasts then sealed the body using Catastrophic Planetary Construction (地爆天星, Chibaku Tensei). Though separated, he named all the Tailed-Beasts, and promised them that though they may be separated that they would always be a part of each other.
Long after the death of the Sage of Six Paths, the Tailed-Beasts were looked upon as destructive monsters, and the various ninja clans sought to capture them to use them as weapons. They would be sealed into the bodies of humans that were called the Jinchūriki. The number of tails is directly related to the amount of power that each of the beasts hold.

Powers & Abilities
The Bijuus each possess immense physical strength and endurance because of their giant proportions, they also possess accelerated healing and vast chakra supplies. They have shown the ability to release shockwaves from their roars as well.
The Bijuus are essentially just masses of Daidarabotchi's chakra given shape and sentience. Even if killed or destroyed, they will just eventually reform.
The Bijuu Bomb (尾獣玉, Bijūdama) is the ultimate offensive technique that is used among all the various Tailed-Beasts, a chakra blast projected from their mouths which can destroy mountains. This is created by molding positive black chakra (+の黒チャクラ, purasu no kuro chakura), and negative white chakra (−の白チャクラ, mainasu no shiro chakura) together. The power is then compressed. The opposing chakra must be balanced at an 8:2 ratio respectively or it will backfire.
Each Bijuu seems to have a unique power from the others, such as Shukaku whom is able to control sand whereas Son Goku is able to create lava, amongst others
A Bijuu's human host is capable of channeling the Bijuu's chakra which not only grants the individual increased strength and chakra, but also forms a protective solidified chakra shroud around the individual in the shape of their Bijuu. This chakra shroud can be shaped and manipulated to a small degree, capable of doing things such as extending additional arms or even creating a doppelganger of the individual.
