Jinchūriki

The, or hosts, have had a Tailed Beast sealed into them. They exhibit extraordinary powers, and in some cases are stronger than their Tailed Beasts because they have the intelligence to use the beast's power effectively.

Each village has used a different seal when creating their Jinchūriki, resulting in different levels of access to the beast's chakra. For example, Konohagakure used the Dead Demon Consuming Seal, while Akatsuki, an organization that spends the series capturing Jinchūriki, uses the Illusionary Dragon Nine Consuming Seals to extract their Tailed Beast and seals it away for future use. They have so far captured seven of the Tailed Beasts.

In the case of Sora, an anime character, he only had a Tailed Beast's chakra sealed into him, not an actual beast. This made him a "Pseudo-Jinchūriki". Although he was granted similar advantages as a real Jinchūriki, his were vastly inferior.

Personality
Jinchūriki are typically lonely people, viewed by those around them as the beast that has been sealed within them. According to Akatsuki, the first two Jinchūriki they captured loathed humanity, and their villages were in fact glad to be rid of them. As the Jinchūriki draws on more of their beast's power, their personality tends to corrode into animalistic instinct. Because their survival depends on the safety of their hosts, Tailed Beasts are very protective of their hosts and act whenever the host's life is in danger.

Abilities
Jinchūriki have access to a unique fighting style depending on their Tailed Beast: Gaara controls sand, Yugito controls fire, and Rōshi controls lava. By training they can gain additional access to their Tailed Beast and its chakra, such that Kirābī can synchronize with his beast and transform himself into it. Not all Jinchūriki can retain control when transforming into their Tailed Beast; Naruto quickly loses the ability to discern between friend and foe, instead becoming a wild animal that attacks anything in sight. A Tailed Beast can also provide its host with constant advantages, such as Gaara's self-activating Shield of Sand and Naruto healing wounds almost as soon as they're inflicted.
