In the world of Naruto, few creatures are more fearsome than tailed beasts and their jinchuriki. While different clans hold high esteem and unique abilities, Naruto's jinchuriki are on another level. After all, they are bonded with ancient monsters. Despite Naruto being a jinchuriki himself, fans were in the dark about the creatures and their purpose for quite a while. It isn't until Naruto: Shippuden where viewers learn more about these mysterious beasts and their hosts. They have far more range than expected; some are hate-filled and bloodthirsty, but a few are gentler souls that didn't ask for their strength either.
In their time with their tailed beasts, the jinchuriki in Naruto learn that the easiest way to utilize them is to befriend them. When it comes to mystical beasts, though, it is hard to gain their trust. Some jinchuriki never do. Others, however, learn to walk in step with their inner demons and grow stronger for it. A strong jinchuriki is just as vital to making the bond work as it is to have a strong beast. Only the best paired monsters and ninja become truly impressive partners with the power to save the world or destroy it.
Updated by Amanda Bruce on October 29, 2021: Though the jinchuriki are a dying breed in the Naruto sequel series, Boruto, they remain a huge part of the Naruto franchise mythology. During most of Naruto's formative years, anyone in a position of power wanted to use a jinchuriki and their tailed beast to their advantage. Even as the jinchuriki are eliminated one by one, fans won't forget the huge impact they had on the original storylines.
Bunpuku
Before Bunpuku could even say the word jinchuriki in Naruto, he was made into one. His village sealed the one-tailed beast, Shukaku, inside him. Eventually, this powerful monster would be recklessly sealed inside the emotionally unstable Gaara, but it started locked in a prison with Bunpuku. The villagers feared young Bunpuku and jailed him, and Shakaku, for the entirety of their life together.
However, against the village's cruelty and prejudice, Bunpuku was a kind pacifist. Without anyone else to talk to, he and the one-tailed beast became friends. While one of the more mentally sound jinchuriki, years spent imprisoned and powerless makes him easily one of the weakest ninja. That doesn't discount his indomitably strong spirit, though.
Kushina Uzumaki
Wife of the Fourth Hokage and second jinchuriki of the nine-tailed beast, Kushina is hardly a weak soul, bearing the burden of Kurama with grace. Though Kushina was afraid of becoming a jinchuriki, she understood its necessity and accepted her role in protecting Konoha.
As an Uzumaki, Kushina has deep chakra levels and the ability to be a great ninja. However, as time went on, she was more drawn to being a friend and wife over the life of a shinobi. If it wasn't for the nine-tails tragedy, she also would have been a great mother. Her sacrifice, along with her husband's, marks one of the saddest deaths in all of the Naruto franchise.
Fu
Unlike many young jinchuriki, Fu grew up protected by the village leader. While many others get shunned, despised, or ridiculed, Shibuki did his best to make sure Fu was defended and cared for. Unfortunately, that upbringing became part of Fu's downfall. Like any wide-eyed young teen, she was desperate to learn what was beyond her secluded lifestyle and signed up for the Chunin Exams, against Shibuki's wishes.
During the exams, she made friends with several Konoha genin. She was an outgoing butterfly, hyperactive to explore the world. Sadly, the Akatsuki tracked her down and, in a feign to befriend her, extracted her seven-tailed beast, Chomei, which ended her life. Though she was likely the happiest of all jinchuriki, it didn't save her from the ills of the world.
Rin Nohara
Sometimes being a jinchuriki for even a short time period can change the course of several lives. When Rin Nohara, a young chunin and beloved team member of Kakashi and Obito, became the host for the three-tailed beast, everything in their lives changed. After all, Isobu wasn't meant to stay in Rin. Enemies captured her to use her as a human time bomb, waiting to slay her and set the beast free once it reached Konoha.
Though it devastated him, Rin decided Kakashi had to end her life instead of risking Konoha. This broke Obito's heart, hardened Kakashi's, and took a fierce, brave ninja from Konoha. Rin may only have been Isobu's jinchuriki for a short time, but her selfless bravery made her a very strong Konoha protector.
Yugito Nii
Though the first jinchuriki fans meet are children, a fair amount of them grow into adulthood or even old age. One example is the powerful jonin, Yugito Nii, jinchuriki of the two-tailed beast, Matatabi. When she was only two years old, she and Matatabi were bound together. Her people put her through years of rigorous, unforgivable training.
While her most distinctive power is her long, blade-like nails, Yugito is also proficient in fire jutsu. Combined with the power of her fearsome beast, Yugito is a force to be reckoned with. It's more a testament to the immense strength of all the jinchuriki that she ranks so low. As a team, Yugito and Matatabi are impressive.
Utakata
While not much is known about how Utakata became a jinchuriki, the fact he comes from the "Bloody Mist" period of Kirigakure speaks volumes. Between the six-tailed beast inside him and his home village's bloody practices, his youth must have been terribly hard.
Utakata's beast, Saiken, is one of the most unique tailed beasts. While most of the creatures are fearsome mammals, Saiken is a soapy slug. His abilities combined with Utakata's innate water powers made the young ninja a bubble master, using them for shielding, entrapment, and more.
Blue B
Blue B had a long, hard life, to say the least. As the jinchuriki of Gyuki, the eight-tailed beast, he had a difficult time keeping the tentacle puppy in line. For most of his life, Blue B was known to have trouble sleeping, plagued by darkness and loneliness. He learned to accept it might be part of the jinchuriki experience, especially for ones like him who were "incompatible" with their beast.
Before Blue B ed on, he lost control over Gyuki and, using B's body, slew eight Kuma ninja. When he came to, he deeply regretted this and wished the next jinchuriki better luck. He fully believed Killer B, his successor, might be able to control Gyuki in a way he never could.
Han
Hailing from Iwagakure, Han is one of the most mysterious of all jinchuriki. Fans only met him once he was resurrected by Kabuto for the Fourth Shinobi World War, but he immediately leaves an impression. Host of the five-tailed beast Kokuo, Han is a calm and reserved ninja. After his ing, his village revered him as the legendary steam ninjutsu master.
Han and Kukuo are possibly the calmest and most friendly of all the tailed-beast duos, as it's not their friendship that keeps Kukuo calm. This beast is one of the few that is pacifistic in nature, only choosing battle when necessary. As a legendary warrior, Han is up there when it comes to strength.
Mito Uzumaki
First jinchuriki of Kurama and wife of the first Hokage, Mito Uzumaki is an impressive woman. When her people were in danger, she took it upon herself to seal the dangerous nine-tailed beast within her. Naruto's ancestral clan is known for their high chakra capacity, and Mito used it to keep the threat of Kurama at bay for the entirety of her life. While Kushina was terrified of housing Kurama, Mito comforted her and told her she was strong enough if she countered its hatred with love.
Though Hashirama saved the village from Madara's assaults, it's Mito's daring decision that helped solidify his ability to do so. Without the nine-tailed beast reigning havoc, he could pacify the true threat. Anyone powerful and bold enough to seal such a beast is a pretty strong character.
Roshi
As a jinchuriki of Iwagakure, Roshi was a powerful ninja with a deep connection to the earth. Tied to fire and rock, he became a fierce, impressive lava ninja as well as the jinchuriki of Son Goku, the four-tailed beast. In his journey to understand his fiery beast better, Roshi left his village to explore the monster inside.
Between his lava, aggressive beast, and heavy attacks, Roshi is no jinchuriki to attack without a plan. Though his hot-headed style aided him in battle, it was also what led to Roshi's downfall. When the Otsutsuki were in pursuit, Roshi attacked before assessing the situation. Roshi was subdued and Son Goku was extracted. Despite his headstrong nature, he deserved a nobler end.
