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 younger brother of the Fourth Raikage, Ē, and the Guardian of Kumogakure.

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 a white 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 Jōnin, 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 one, losing five in battle against Taka and another during his fight with Kisame Hoshigaki. As Kisame is about to finish him off with it, Darui breaks it by throwing a lightning infused shuriken at it: thus saving Bee's life but breaking the sword.

Personality
Killer Bee is very proud of his own power, and like Naruto, has great overconfidence and can be quite cocky and stubborn, especially in terms of his own strength, demanding 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 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, an attribute that Gaara compares Naruto Uzumaki in regards with. The Raikage also notes that he is the only being that Killer Bee will listen to, as he is able to keep him in check. Despite all this, Killer Bee 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. He had also praised Sasuke after their fight, stating he was one of the strongest shinobi he had ever fought.

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 lazy and not much of a hard worker, ready to transform into his full Eight-Tails form and faked his defeat and capture, only to escape from his village for a "vacation". When Ē, 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.

However, when someone close to him is in danger, Killer Bee has no qualms about putting himself at risk to save them, if necessary, 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.

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

\ious, 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 octopus chakra. Killer Bee then regained conciousness after obtaining some chakra from Samehada, but still appears to be in a weakened state. Kisame kicks Samehada aside and prepares to sever Bee's legs with one of his own swords. After another failed attempt to kill Kisame with the pencil he threw at him earlier, Killer Bee is saved by his brother, the Raikage, Shī and Darui. Killer Bee and his brother then finish off Kisame by performing a Double Lariat to decapitate him. After that, Bee got reprimanded by Ē for running away from the village.

Abilities
As the Guardian of Kumogakure and jinchūriki of the Eight-Tailed Giant Ox, Killer Bee is an extremely powerful ninja, capable of overwhelming the entire Team Taka all by himself, and has had his skills praised by several Kumogakure ninja, including his older brother, Ē. Madara Uchiha 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 get very excited and turn against Kisame.

Physical Prowess
Bee possesses immense physical strength and combat prowess, capable of disarming a skilled opponent like Suigetsu with his bare hands. He is also shown to be incredibly durable in battle, having received a solid kick to the neck from Sasuke Uchiha only to drop his sword and begin writing lyrics, escaping unscathed after being hit by Sasuke's Chidori, and blasted from behind with Jūgo's Boosting Jet Pistons. Killer Bee has a fighting style which is similar to that of the Raikage's because they both use wrestling moves instead of standard taijutsu. He supplements the speed and power of his taijutsu with his Tailed-beast cloak. Another form of Killer Bee's amazing strength was when he and the Raikage took Kisame's head off almost instantly, while Killer Bee was using his off hand.

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 very 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 the former being a highly trained swordsman and the latter having the Sharingan. He is also capable of cutting through almost anything. He can also use these blades as mid-range projectiles,and coat them lightning chakra to slice right through the target. 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 charge a 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 with 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 Mangekyō 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. He can also partially transform parts of his chakra shroud into parts of the Eight-Tails body. When he fully transformed, he can easily fire massive chakra blasts many times the size of its already giant body, but Killer Bee was forbidden from transforming by Ē.
