Killer B

is a shinobi from Kumogakure and the jinchūriki of the Eight-Tailed Giant Ox. He is also the mentor of Team Samui. It is hinted he comes from the Yotsuki clan. He is the current Raikage's younger brother.

Appearance
Killer Bee is very similar in terms of appearance with his older brother, being dark-skinned and possessing a muscular build, as well as white hair and beard. On his right shoulder, he has a tattoo that says ; and on his left cheek, he has a tattoo of a bull's horn (correspondingly, the Eight-Tails has horns like a bull, and the left one is missing).

Killer Bee wears oval-shaped sunglasses and a white-colored forehead protector. He also wears a white-colored one-strap-over-one-shoulder Flak Jacket of a Kumogakure Jonin, with a red rope tied around his waist, white hand-bands, and a white scarf around his neck. He carries seven swords on his back, but currently has only two, losing five others in battle against Taka.

Personality
It seems that he demands respect from others and asks to be called and his tailed beast be called. He also appears willing to speak in song, more specifically in rap-style, even when confronted with potential threats. He will even stop in a middle of a fight to write whatever rhymes come to him, even if they are no good. This sometimes causes his opponents to become greatly bothered by him. He has a casual relationship with the Eight-Tails, frequently engaging in friendly conversation with it. The Raikage notes that he is the only being that Killer Bee will listen to.

Despite Killer Bee's conceited arrogance, he knows talent when he sees it, and respects those with it. The primary example is his fellow Kumogakure jinchūriki, Yugito Nii, who he looks up to for her extreme skills.

Killer Bee appears to dislike light, as he complained when he exited his training area to find that the sun had risen.

Killer Bee seems to wish to leave his village for a vacation due to being tired of being the guardian and he can also be very deceitful; as he transformed into his full Eight-Tails form and faked his defeat and capture, only to escape from his village for a "vacation". When the current Raikage, Darui and Shī learned that Killer Bee was not captured by Akatsuki, they immediately guessed his intentions and were not surprised by it, though they were very displeased. He does, however, seems to care for those who shares similar interests with him, as seen when he prioritized the safety of his singing master, Sabu and his pet Ponta first over confronting Kisame head-on when the Akatsuki confronted his entourage

The Raikage has noted that Killer Bee is not the type of person to work with the strategies created by people and that he would only bring chaos into a battlefield. Gaara compares Naruto Uzumaki in regards to this attribute.

Hunt for the Eight-Tails arc
Taka tracks Killer Bee to the Valley of Clouds and Lightning soon after he finishes training with his tailed beast. When Suigetsu attacked him, he easily overpowered him, and uses Suigetsu's sword to defeat Jugo afterwards. He later shows an unorthodox sword style where he manages to hold all seven of his swords in a rather awkward pose; this is deceiving as his seven sword style is extremely formidable and he even fatally wounds Sasuke Uchiha as Sasuke could not track the sword movements even with his Sharingan.

As he moves in to finish Sasuke, Suigetsu comes to save him while Jugo attacks from behind. Even while the three fighting him at once Killer Bee appears unfazed by their attacks and quickly moves away from their location. Finally getting annoyed with Taka, Killer Bee announces he will unveil the. Killer Bee formed his own demon chakra shield and proceeded to attack Taka. Sasuke then attempted to place him in a genjutsu but as Sasuke lowered his guard, Killer Bee struck. In the end, he blasted a hole in Sasuke's chest and neck claiming that a jinchuriki that has full control of his beast can become immune to genjutsu. He then completely released the full power of the Eight-Tails, ordering the team to cower in fear of him.

Sasuke then hit the Eight-Tails with Amaterasu. As one of it's tails was about to fall on Karin, Sasuke cut it with Chidori Sharp Spear. Killer Bee disguised himself as the cut part of the tail and escaped. The Eight-Tails transformed into an unconscious form of Killer Bee. With his defeat, Sasuke carries him away. When his brother, the current Raikage, learns of his capture, he makes plans to deal with Sasuke and Akatsuki. When Akatsuki later tries to extract the Eight-Tails from Killer Bee's body, they find that it is only one of the beast's tentacles disguised as Killer Bee. He had made the appearance that he was captured to escape his village, where he had grown bored of being a guardian. Since his village now believes him to be captured, he uses this as an opportunity to take a "vacation" from being a guardian. As Eight-Tails comments that a new era is coming, Killer Bee thinks he means about his new music career.

Kage Summit Arc
Killer Bee is shown to be near a far off mountain practicing his music career with his seemingly new music teacher, Master Sabu, who thinks Killer Bee lacks passion in his singing. Later, Killer Bee is approached by Kisame Hoshigaki saying his Samehada tracked his powerful chakra scent. Killer Bee says he'll make quick work of Kisame.

Much to Killer Bee's shock, all of his lightning techniques fail against Kisame as Samehada continues to eat all the chakra that gets close enough, even his demon chakra. Eventually, Kisame has Samehada unleash its true form. Later as the battle progresses, Killer Bee uses the Eight-tail's chakra to transform into a seven-tailed version of the Eight-tails, similar to a six-tailed Naruto along with the skeleton of an ox. Killer Bee then uses the Lariat technique on Kisame severely injuring him to the point of exposing Kisame's ribcage, while Samehada absorbs the Eight-Tails' chakra. Kisame then uses Samehada to heal himself and combines with Samehada transforming himself into a monstrous shark-like form. Bee continues to fight Kisame and eventually gets a head on attack from Kisame in which he partially transforms one of his tails into a Octopus tail and wraps Kisame in it. When Kisame tried to slice off Killer Bee's legs after he was rendered unconscious, Samehada dug itself into the ground to prevent that from happening. It also attacked Kisame to protect Killer Bee as it has grown fond of his chakra. Killer Bee is now conscious again after obtaining some chakra from Samehada, but still appears to be in a weakened state.

Abilities
Killer Bee is an extremely powerful ninja, capable of overwhelming the entire Team Taka, and has had his skill praised by several Kumogakure ninja, including his brother, the current Raikage. Madara claimed that he is the perfect host. Similar to how other Jinchūriki obtain physical traits from their inner demon, Killer Bee is able to produce ink from his mouth, which he mainly uses to write lyrics when he is lacking of regular writing tools or to blind his opponent. As expected of a Jinchūriki, Killer Bee has a very large reservoir of chakra, enough to make Samehada to get very excited and taken a liking to him.

Taijutsu
Bee possesses immense physical strength and combat prowess, capable of disarming a skilled opponent with his bare hands. He is also shown to be incredibly durable, have received a solid kick to the neck from Sasuke only to drop his sword and begin writing lyrics, escaping unscathed after being hit by Sasuke's Chidori, and blasted from behind with Jugo's rocket-augmented attack.

Sword Skills
As a swordsman, Bee specializes in swordplay. Possessing a unique fighting style, Bee holds his blades in between the joints of his arms, left leg, stomach, the left side of his neck, and in his mouth. As strange as it appears, Bee is quite skilled with this, spinning around like a buzz saw and overwhelming his opponent with all of the varying swings, giving him great versatility. When he finds an opening, Bee can impale his opponent with most of his swords quickly and simultaneously. Neither Suigetsu nor Sasuke could read his sword work, despite being a highly trained swordsman and having the Sharingan. capable of cutting through almost anything. Also, by covering himself with the Eight-Tailed Beast's chakra, he creates an "Eighth" sword.

Lightning Element
During the battle with Sasuke he displayed the ability to flow lightning-natured chakra through his blades to increase their cutting power, similar to Sasuke's own jutsu. Killer Bee's prowess in Lightning Release techniques is so great, he can even charge sharp but weak pencil-point to pierce straight through a large tree trunk and even through the ground. As stated by Kisame, Killer Bee is able to do this by increasing the vibration frequency of his lightning chakra to surpass the standard penetrative force of wind chakra.

Jinchūriki Transformations
Like other jinchūriki, Killer Bee has the ability to create a chakra cloak by drawing on part of his demon's power. He can then form this chakra into the form of two horns, and use them to attack the enemy;Or he can partially transform into his tailed beast. a technique called Lariat. This attack has incredible speed and power, but the linearity of his movements makes him easier to predict. Because he has a strong relationship with his own tailed beast, it acts as his partner in battle, disturbing his chakra to dispel even genjutsu from Mangekyo Sharingan.

Like his fellow Cloud shinobi, Yugito Nii, Killer Bee is able to become his tailed beast itself with great ease. Unlike her, however, he can retain complete control even in this fully released state, partially transform parts of his chakra shroud into parts of the Eight-Tails body. When he fully transforms, he can easily and repeatedly fire massive chakra blasts many times the size of its already giant body, but Killer Bee was forbidden from transforming by the current Raikage.
