Jinchūriki

The are humans that have a tailed beast sealed within them. They exhibit extraordinary powers, and in some cases are more powerful than their tailed beasts, because they have the intelligence to use the beast's powers effectively.

The first jinchūriki was the Sage of Six Paths, who sealed the Ten-Tailed Beast within himself to save the world, but before his death, the Sage divided the Ten-Tails' chakra into nine separate tailed beasts and sealed the Ten-Tails' body into the moon. The Second Kazekage of Sunagakure was the first to research the jinchūriki, with the other villages following soon after. Each village has used a different seal when creating their jinchūriki, however Mito Uzumaki was the first known Jinchuriki since the Sage of the Six Paths. For example, Konohagakure used the Dead Demon Consuming Seal, while Akatsuki, an organization whose role in the series is to capture the jinchūriki, uses the Illusionary Dragon Nine Consuming Seals to extract the tailed beasts, and seal it away for future use. They have, as of the Fourth Great Shinobi World War, captured seven of the nine beasts.

In order to prevent the jinchūriki from turning traitor, it is tradition for the host to be selected from the family of the village's own Kage. In this way, the jinchūriki not only has strong ties of loyalty to village and their leader, but they also serve to show off the Kage's might. For example, Naruto is the son of the Fourth Hokage, Gaara is the son of the Fourth Kazekage, Killer Bee is the brother of the Fourth Raikage. What relationships the other jinchūriki hold to their Kage (except Fū, whose village has no Kage leader) are currently unknown.

The seal that keeps the Tailed Beast insides its host is at its weakest when a female Jinchuriki is in child birth du eto the seal using some of it power to nourishes the child while inside the womb.

Personality
Jinchūriki are typically lonely people, viewed by those around them as the beast that has been sealed within them, leading to prejudice and being hated and feared. According to Akatsuki, the first two jinchūriki they captured loathed humanity, and their villages were in fact glad to be rid of them. However, certain jinchūriki refuses to waver, despite being shunned, instead having a cheerful demeanor, and eventually earning respect. Such examples are Killer Bee and Naruto Uzumaki.

As the jinchūriki draws on more of their beast's power, their personality tends to corrode into animalistic instincts. Because their survival depends on the safety of their hosts, the tailed beasts are very protective, and will act whenever their hosts' lives are in danger. Normally, these hosts have little control over themselves as they transform deeper into their tailed beast forms, and become more beastly in battle. However, Yagura and Killer Bee, the only two jinchūriki to have full control of their tailed beasts, can retain complete consciousness and control even after a full transformation.

Abilities
Jinchūriki have access to a unique fighting style, depending on their tailed beast: Gaara controls sand, Yugito controls fire, Rōshi controls lava, Killer Bee can spit ink, and Naruto has high stamina and rejuvenation. By training, they can gain additional access to their tailed beast and its chakra, such as Killer Bee being able to synchronize with his beast, and transform himself into it. Not all jinchūriki can retain control when transforming into their tailed beast; when Naruto taps into his four-tailed form, he loses the ability to discern between friend and foe, and attacks anything in sight. A tailed beast can also provide its host with constant advantages, such as Gaara's self-activating Shield of Sand which automatically protects him, even from self-injury and Naruto's healing factor that immediately activates as soon as he incurs wounds.

Similar Cases
In the anime, Sora only had a part of the Nine-Tails' chakra sealed into him, which made him a "pseudo-jinchūriki." Even though he was granted similar abilities to those of a real jinchūriki, his were vastly inferior.

In Naruto Shippūden 2: Bonds, Amaru had the Zero-Tailed Masked Leech sealed within her, but because the Zero-Tails is not an actual tailed beast, Amaru is not considered a jinchūriki.

In the anime, Yūkimaru had the ability to control the Three-Tails. While his appearance is similar to that of Yagura, the Three-Tails' former jinchūriki, with the same distinctive eye and hair color, no confirmed connection exists between the two. The tailed beast was not actually sealed inside of him, and, thus, he was not a real jinchūriki.

Trivia

 * Gaara died when Akatsuki removed Shukaku from his body, but he was later revived. Although he no longer has Shukaku sealed within him, he can still control sand. It is unknown if other jinchūriki would have kept their powers under the same circumstances had they survived their beast's extraction.
 * Takigakure is the only village, not belonging to one of the Five Great Shinobi Countries, known to have had a jinchūriki.
