The nine tailed demons and the juubi. (Do not post in this)

[Asuka Uchiha Kitari]

The tailed beasts are nine 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 an amount from one to nine. The tailed beasts are large, living forms of chakra, sometimes referred to as "Chakra Monsters" (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 speak and better utilize their power.

The tailed beasts have been around since long before the founding of the ninja villages. In the beginning of the ninja history, there existed one demon, the Ten-Tailed Beast, that plagued the planet until the Sage of the Six Paths defeated and sealed the beast within himself, making him the first jinchūriki. On his deathbed, he divided the Ten-Tails' chakra into the nine other tailed beasts and sealed its body in the moon.
By the time of the formation of the shinobi villages, Hashirama Senju, the First Hokage, managed to capture and control some of them with his Wood Release techniques, and used them as peace treaties to the other great shinobi nations in order to stabilize the balance of power between them. After his death, however, the shinobi nations couldn't control these giant demons themselves and they began to run wild, so the nations instead moved to seal the tailed beasts within humans.

The One-Tailed Shukaku- is a monster tanuki. It was sealed within Gaara of Sunagakure since his birth. It has been captured by Deidara, then extracted and sealed by Akatsuki. is intelligent, but also incoherent, giving it the demeanor of a drunkard, which fits well with the typical depictions of tanuki in Japanese folklore. Shukaku itself translates to "drunk" in Japanese. Like other tailed beasts, its innate rage and bloodlust influences its behavior. According to Gaara,"It relishes the opportunity to kill anyone in sight, even more so during a full moon". Gaara knows how to control it sometimes, but most of the time it simply forces him to let it out.

As Shukaku's jinchūriki, Gaara has the ability to move and levitate sand at will. In addition, Shukaku protects him at all times with the Shield of Sand, regardless of his will (even self-inflicted injuries are prevented by the sand). He also suffers from lifelong insomnia, a side-effect of being Shukaku's jinchūriki. Whenever he fell asleep, Shukaku would eat away his personality, turning him into a monster.
When angry or in a state of bloodlust, Gaara can use the sand in his gourd to take on the form of a miniature Shukaku, or even create a giant copy of Shukaku's body. It is only when Gaara begins to take on Shukaku's form that he is allowed access to its wind element, such as Wind Release: Drilling Air Bullet. Gaara can even allow Shukaku to take on the full Shukaku form by going asleep, but is left vulnerable, as his sleeping body is left unprotected on Shukaku's head.

Two-Tailed Monster Cat- is a blue-flamed, odd-eyed bakeneko. It was sealed within Yugito Nii of Kumogakure when she was two years old. It has been captured by Hidan and Kakuzu, then extracted and sealed by Akatsuki. Like the One-Tailed Shukaku, many people believed that the Two-Tails was once a human that turned into a living ghost. As the Two-Tails' jinchūriki, Yugito had the ability to transform into the monster cat, giving her access to its strength and its ability to breathe fireballs from its mouth without losing control.

The Three-Tailed Giant Turtle - is a large, turtle-like tailed beast. It was formerly sealed in Yagura of Kirigakure, but was extracted for unknown reasons. It has been captured by Deidara and Tobi, then sealed by Akatsuki. At some point in the past, the Three-Tails was sealed within Yagura, the Fourth Mizukage. It was later extracted from its host for some reason, and escaped into the wild. Because it did not have a host, it was not intelligent enough to effectively utilize its great strength, instead being reduced to animal instincts.
The Three-Tails was depicted as having no hind-legs, with only a pair of fore-legs and its three distinctive tails. Its right eye was constantly closed, indicating some sort of injury. Because of this, it was particularly vulnerable to attacks directed at its left eye.

Other than being a very fast swimmer despite its size, the Three-Tails' abilities were not seen in the manga. Tobi suggested that Kisame would have been a better choice for capturing the beast, given its affinity for water. In the anime, its abilities were greatly elaborated upon, many of which dealt with its size: it could roar to repel attacks; it could produce a large tidal wave that spread away from it in all directions; it could strike with any of its three spiked tails to break through most defenses. Its skin was resistant to attack in a similar fashion.
Of the beast's more specialized abilities, it could produce a hallucinogenic mist that exploited the victim's insecurities and forced the victim to face them. It could also shoot white, Menacing Ball-like shockwaves. When it swallowed something, thousands of "mini-clones" of itself would attack what it had eaten within its gut, presumably to facilitate digestion.

The Four-Tailed Monkey-is a tailed beast sealed within Rōshi of Iwagakure. It has been captured by Kisame Hoshigaki, then extracted and sealed by Akatsuki Rōshi was somehow defeated and captured by Kisame. Kisame had difficulty capturing Rōshi because of the Four-Tails' ability of Lava Release. The Four-Tails was later extracted and sealed, leading to Rōshi's death. As the jinchūriki of the Four-Tails, Rōshi had the ability to use its power of Lava Release, a combination of fire and earth the likes of which have rarely been seen outside of kekkei genkai.

The Five-Tailed Dolphin Horse-is a tailed beast sealed within Han from Iwagakure. It has the body of a horse, but the head is based off of a dolphin. It has since been captured, extracted, and sealed by Akatsuki.

The Six-Tailed Slug- is a demon slug sealed within Utakata of Kirigakure. It is a giant, bipedal slug with six tails. It has been captured, extracted, and sealed by Akatsuki.

The Seven-Tailed Horned Beetle- is a demon kabutomushi sealed within Fū from Takigakure. It resembles a gigantic, blue rhinoceros beetle, with six of its seven tails resembling green insect wings, along with the seventh tail, all growing from the end of its abdomen. It has been captured, extracted, and sealed by Akatsuki.

The Eight-Tailed Giant Ox- is a demon ushi-oni sealed within Killer Bee of Kumogakure. Little is known about the Eight-Tails' strength so far. As the Eight-Tails' jinchūriki, Killer Bee can transform himself into the Eight-Tails and can access its high-level chakra without losing control. Killer Bee is one of the two jinchūriki who has been known to be able to fully control his tailed beast's powers, the other being Yagura. It has been shown to fire an attack similar to the Four-Tailed Fox Menacing Ball, but with much greater force. Killer Bee is also able to use the Eight-Tails to block his chakra to break illusions, even ones cast from a Mangekyō Sharingan. Killer Bee can also create ink because of the octopus nature that his tailed beast resembles.

The Nine-Tailed Demon Fox- is the most powerful out of all nine of the tailed beasts; a single swipe from just one of its nine tails can raise tsunamis and flatten mountains. After the Nine-Tails attacked Konohagakure, Minato Namikaze, the Fourth Hokage, sacrificed his own life by sealing it within his newborn son, Naruto Uzumaki. The Nine-Tails is a giant, malevolent fox demon of mass destruction. It is also intelligent, and has a sadistic and sarcastic personality. However, it does have a distinct sense of honor and pride, and possesses a loathing respect for Naruto and Minato.
At first, the Nine-Tails relished the thought of killing Naruto, but it soon realized that it shares the same fate as Naruto as long as it is sealed within him; so it has no choice but to cooperate with Naruto or it will die. It will go to great lengths to preserve its own life, as shown when it forces its chakra into Naruto whenever his life is in danger. Later in Part II, the Nine-Tails became angry and contemptuous at Naruto when he rejected its chakra, although this was merely the rage of missing the opportunity to usurp control over Naruto's mind and body, which would have weakened the seal. However, it will back down if Naruto threatens to harm or kill himself.
The Nine-Tails has a deep hatred for the Uchiha clan and their Sharingan, likely because of the many times Madara manipulated it in the past. It even remarked that Sasuke Uchiha is a lot like Madara because of his power of the Sharingan.[1] According to the third Naruto Databook, the Nine-Tails is the only one who knows the truth about the Uchiha clan and about Naruto. However, it appears that it has no intention of telling what it knows.

The Ten-Tailed Beast- All nine of the tailed beasts are but portions of chakra divided from the Ten-Tails. Madara Uchiha's ultimate goal, the Moon's Eye Plan, is to capture and merge all nine of the tailed beasts back into the Ten-Tails, and become its host to cast the reflection of his Sharingan on the moon, casting a genjutsu known as the Infinite Tsukuyomi which will put the entire world under his control. Centuries before the founding of the hidden villages, the Sage of the Six Paths saved the world from the Ten-Tails. He managed to subdue the beast and sealed its chakra within his own body, becoming the first jinchūriki.
However, this offered merely a temporary solution to the menace; in the event of his death, the seal would dissolve and the Ten-Tails would once again be unleashed upon the world. Knowing this, the Sage devoted the remainder of his life to searching for a more permanent solution. Ultimately, the Sage succeeded by dividing up the chakra of the Ten-Tails into the nine monstrous entities that would later become known as "tailed beasts" and scattering them throughout the world. As a final precaution the Sage, using his Chibaku Tensei jutsu, entombed the physical remains of the Ten-Tails within a colossal stone prison and hurled it into the heavens, creating the moon.
So far, the Ten-Tails has only been seen once, in silhouette, but the form of its body seemed to be closest to that of the Nine-Tailed Demon Fox's body. Also, it appeared to have only one eye, which had four Rinnegan-like concentric circles, with nine Sharingan-like tomoe in the three circles closest to the pupil.
As the fusion of all nine tailed beasts, the Ten-Tails is said to possess massive and overwhelmingly foul chakra that is potent enough to bring total despair and destruction to the world. The astonishing feat of not only successfully sealing the Ten-Tails, but also suppressing it, made the Sage a god-like hero throughout
