Killer B (Killer Bee) is one of the major supporting characters in the series, a shinobi from Kumogakure and the jinchūriki of Gyūki, the Eight-Tails. Killer B is very proud of his own power and also very proud of who he is. Like Naruto Uzumaki, who has great overconfidence, Killer B can be quite cocky and stubborn, especially in terms of his own strength, demanding respect from others and asks to be called "Lord Jinchūriki" and his tailed beast be called "Lord Eight-Tails". B has a special way of expressing his pride through song, more specifically in rap-style and tends to use "Bakayarō! Konoyarō!" when referring or speaking to others. He will even write his rhymes in the middle of a fight, or during an important meeting, even if they are no good, which is usually the case. This sometimes causes the people around him to become greatly annoyed by him. B doesn't respect anyone who would make fun of rap or his lyrics.
The Raikage has noted that Killer B is not the type of person to work with the strategies created by people and that he would only bring chaos into a battlefield; in his youth he was already seen completing missions, that were supposed to be assigned for both him and his brother, without A's knowledge. The Raikage also notes that he is the only being that B will listen to, as he is able to keep him in check. Despite all this, B knows talent when he sees it, and respects those with it. The primary example is his fellow Kumo jinchūriki, Yugito Nii, who he looked 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. B has a very close relationship with his older brother, the Raikage. According to Motoi, the reason behind him becoming a jinchūriki was for the sake of his brother, even if it meant being shunned by the villagers. He didn't complain, and was always cheerful and determined.
Due to the fact that he was confined to the village very soon after his brother assumed office and made the village's guardian, B desperately wished for a vacation and was even ready to fake his capture for one. When the Fourth Raikage, Darui and C learned that B was not captured by Akatsuki, they immediately guessed his intentions and were not surprised by it, though they were very displeased. This lead to him receiving his brother's "Iron Claw" as punishment. B also tends to fist bump with others. This ties into his rapper personality and also serves as a means of communication of sorts, with others without the need to speak.
However, when someone close to him is in danger, Killer B has no qualms about putting himself at risk to save them, if necessary, as seen when he prioritised the safety of his singing master Sabu and his pet, Ponta over confronting Kisame head-on when the Akatsuki confronted his entourage. This caring nature differentiates him from a typical jinchūriki, most of whom are cynical and uncaring towards others due to their circumstances. However, it was hinted that his past as a jinchūriki may not have been unlike Naruto's, since Motoi claimed that being a fellow jinchūriki, B understands what Naruto went through. He has a casual relationship with Gyūki, frequently engaging in friendly conversation with it, even sitting upon its nose when not in combat. He was also completely unaffected by Naruto's Harem Technique, resisting lustful advances and even appearing indifferent. However, he is not completely unaffected by such things, as he noticed Tsunade's chest, which his brother reprimanded him for and he later stared at Yugito's own chest when it was shown during his fight with Tobi's Six Paths. This is later explained as having a preference toward older woman, at one point confessing it during the fight against Tobi, much to his tailed beast's surprise and chagrin.
B is also very kind and compassionate, having befriended all the giant animals on the Island Turtle which may indicate that he has a liking for animals, as well as never expressing any ill will towards Motoi who tried to take his life, nor against the villagers who used to shun him. [Source: wikia]
