No, Sasuke did not successfully capture the 8-tails jinchuriki Killer B. Killer B was the jinchuriki or host of the 8-tailed beast Gyuki. During the Fourth Great Ninja War arc in Naruto Shippuden, Sasuke attempted to capture Killer B under orders from the Akatsuki leader Tobi. However, Killer B was able to outsmart and overpower Sasuke, faking his own capture and death. So in the end, Sasuke failed in his mission to deliver Killer B and the 8-tails to the Akatsuki.
Background on Sasuke
Sasuke Uchiha was originally a member of Team 7 in the Hidden Leaf Village along with Naruto Uzumaki and Sakura Haruno. He possessed the Sharingan eye and was the last surviving member of the Uchiha clan after his brother Itachi killed the rest of their family. Sasuke left the Leaf Village and joined up with Orochimaru to gain more power, driven by his desire for revenge against Itachi. After defeating Orochimaru, Sasuke formed his own team Taka (Hawk) and aligned himself with the Akatsuki. His goal was to destroy the Leaf Village which he blamed for the tragedy of his clan.
Sasuke Joins the Akatsuki
After Itachi’s death, Sasuke learned the truth about his brother’s past and the real reasons for killing their clan. Feeling lost and betrayed, Sasuke decided to take revenge on the Leaf Village elders who had forced Itachi’s hand. To do this, he aligned himself with Tobi, the mysterious leader of the Akatsuki. Tobi told Sasuke about the history of the village and how it had mistreated the Uchiha clan. Convinced by Tobi’s version of events, Sasuke agreed to work together with him and Akatsuki. Tobi promised to help Sasuke get his revenge after the Akatsuki completed their plans to capture all the tailed beasts.
The Akatsuki’s Goal to Capture the Tailed Beasts
The Akatsuki was an organization made up of rogue ninjas from various villages. Their goal was to capture all nine of the tailed beasts, powerful creatures of chakra that were sealed inside human hosts called jinchuriki. By extracting the tailed beasts from their jinchuriki hosts, the Akatsuki aimed to harness their immense power for world domination. Each Akatsuki member was assigned to capture a specific tailed beast. At the time Sasuke joined, the Akatsuki had already captured 7 of the 9 tailed beasts, including the 7-tails that was sealed inside Fuu from the Hidden Waterfall Village.
Sasuke is Assigned to Capture Killer B and the 8-Tails
After proving himself by capturing Orochimaru’s hideout, Sasuke was assigned by Tobi to capture the 8-tailed beast, Gyuki. Gyuki was sealed inside Kumogakure shinobi Killer B, the younger brother of the Raikage. Capturing Killer B would be essential for the Akatsuki’s plans. With his Sharingan abilities and lightning-based attacks, Sasuke seemed ideally suited for subduing a jinchuriki like Killer B. Tobi warned Sasuke not to underestimate Killer B or kill him in the extraction process. Meanwhile, Sasuke was determined to succeed in his mission to get closer to his goal of destroying the Leaf Village.
Killer B’s Jinchuriki Powers
Killer B was originally made Gyuki’s jinchuriki to become Kumogakure’s ultimate weapon. As Gyuki’s host, Killer B had access to the 8-tails’ massive chakra reserves and could draw on its power when needed. He could form various chakra tails in his Version 1 and Version 2 jinchuriki forms. In full Version 2 form, he resembled Gyuki with 8 octopus tentacles emerging from his back. Killer B could also form a partial Version 2 transformation just on his arm to increase his strength and speed. On top of his jinchuriki abilities, Killer B was an extremely skilled swordsman, using 7 special swords in battle. His signature fighting style was highly unpredictable, making him very dangerous.
Killer B’s Ability to Transform into Gyuki
As Gyuki’s jinchuriki, Killer B had the unique ability to fully transform into the 8-tails. This was something none of the previous jinchuriki hosts could accomplish. By fully transforming, Killer B could access the 8-tails’ massive chakra and destructive power. In his full 8-tails form, Killer B took on Gyuki’s appearance – a huge ushi-oni (bull-octopus demon) with 8 tentacle tails. In this form, he gained immense strength, durability and access to Tailed Beast Balls, immensely destructive chakra balls that could devastate an entire town. Killer B’s mastery of his tailed beast made him a formidable opponent for Sasuke.
Killer B’s Control Over Gyuki’s Chakra
Unlike some other jinchuriki who struggled with their tailed beasts, Killer B had a very cooperative and friendly relationship with Gyuki. This allowed Killer B to access Gyuki’s chakra at will without losing control of himself. Killer B and Gyuki could communicate telepathically within his subconscious, even devising battle strategies together. Furthermore, Killer B’s seal allowed him to fully control how much of Gyuki’s chakra he accessed at any time. He could carefully regulate 1 to 8 tails worth of power. This high level mastery prevented Gyuki’s chakra from overwhelming him. Overall, Killer B had complete control over his tailed beast abilities.
Sasuke Attacks Killer B
When Sasuke and his team Taka arrived in Kumogakure, he immediately sought out Killer B’s chakra and launched a surprise attack. However, Killer B quickly gained the upper hand with his unpredictable sword skills and lightning Release techniques. When Sasuke used his Sharingan genjutsu, Killer B countered it by substituting with one of his swords. Sasuke and his team kept up their assaults but Killer B successfully blocked or evaded them all, even as he transformed into his 7-sword Version 2 form. He then fully transformed into Gyuki itself, revealing his full 8-tails jinchuriki power.
Killer B Overwhelms Sasuke and Team Taka
Now in his 8-tails form, Killer B completely overwhelmed Sasuke and Taka. He could regenerate from their attacks almost instantly due to Gyuki’s chakra. Sasuke resorted to using Amaterasu black flames, but they had almost no effect. Killer B then formed a Tailed Beast Ball and fired it at Sasuke, who managed to block it using his Mangekyo Sharingan’s Susano’o power. However, Killer B’s assault had destroyed most of the surrounding forest and Team Taka was running out of options. Recognizing Killer B’s power, Sasuke decided they needed to regroup and reformulate a new battle strategy before attempting capture again.
Killer B Fakes His Capture
After their first battle, Killer B fooled Sasuke and Team Taka into thinking they had successfully captured him. When Sasuke next encountered Killer B, the Kumo ninja pretended to have been heavily weakened and immobilized. Believing Killer B’s powers and Gyuki’s chakra had been sealed, Sasuke and his team transported him back to the Akatsuki hideout. However, this was all an act on Killer B’s part. He had substituted himself with a tentacle so he could escape. Back in Kumogakure, Killer B alerted the Raikage A that the Akatsuki was targeting jinchuriki hosts. The Raikage then assembled the other Kage for an emergency summit meeting.
Killer B Substitutes Himself with Gyuki’s Tentacle
To fool Sasuke into thinking he had been captured, Killer B utilized an ingenious deception. Right before their second encounter, Killer B severed one of the 8-tails’ tentacle tails. He then used the Transformation Jutsu to shape the tentacle into a copy of himself. When Sasuke used his powers to immobilize what looked like Killer B, it was actually just the severed tentacle. With his captors fooled, the real Killer B slipped away unnoticed. This strategy demonstrated both Killer B’s wit and his superb chakra control to transform the tail.
Killer B Alerts the Raikage and Kage about the Akatsuki Threat
After escaping from Sasuke and Akatsuki, Killer B informed his brother the Raikage about the organization’s plans to capture jinchuriki. The Raikage recognized the grave threat this posed to all the villages who relied on their tailed beasts for military power. He quickly contacted the other Kage – from the Leaf, Sand, Stone, Cloud, and Mist villages – to discuss forming a Shinobi Alliance against the Akatsuki. Killer B’s escape and subsequent warning enabled the ninja villages to unite against the common threat. This later proved critical in the Fourth Great Ninja War against Tobi and the Akatsuki.
Conclusion
In summary, Sasuke ultimately failed in his mission to capture Killer B and deliver the 8-tails to the Akatsuki. He was unable to counter Killer B’s unpredictable fighting style and mastery over Gyuki’s chakra. Even Sasuke’s Mangekyo Sharingan proved ineffective. Killer B’s decision to fake his own capture also allowed him to escape and warn the other Kage about the Akatsuki’s plans. This proved a major setback for the Akatsuki. Sasuke’s defeat showed that even his powers as an Uchiha were insufficient against a jinchuriki who could fully control their tailed beast. Killer B’s victory was a defining moment that tilted the balance against the Akatsuki in the leadup to the Fourth Great Ninja War.
