Killer Bee is a shinobi from Kumogakure. He is the current jinchuriki of the Eight-Tails, Gyuki, since he managed to master the beast and protect his village, unlike his predecessors. Despite being responsible for the village’s protection, Bee aspires to become the world’s greatest rapper.

Killer Bee has dark skin and a muscular built individual, as well as blonde hair and a goatee. On his right shoulder, he has a tattoo of the kanji for “iron”, which is the Iron Armour Seal that is used to seal Gyuki into him, and on his left cheek, he has a tattoo of a bull’s horn. His top lip also has a slightly darker hue than his bottom one.

Killer Bee wears oval shaped sunglasses and a white-coloured forehead protector. He also has his village’s standard one-strap-over-one-shoulder flak jacket, and a long red rope belt tied around his waist, the standard Kumo hand and shin guards, high-calf shinobi sandals, and a white scarf around his neck. He carries two swords around his back and the other five inside Samehada.

Killer Bee is very proud of his own power and also very proud of who he is. Like Naruto Uzumaki, who has great overconfidence, Killer Bee can be quite cocky and stubborn, especially in terms of his own strength, demanding respect from others and asks to be called “Lord Jinchuriki” and his tailed beast be called “Lord Eight-Tails”. Bee 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. Bee doesn’t respect anyone who would make fun of rap or his lyrics.

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; in his youth he was already seen completing missions, that were supposed to be assigned for both him and his brother, without Ay’s knowledge. The Raikage also notes that he is the only being that Bee will listen to, as he is able to keep him in check. Despite all this, Bee knows talent when he sees it, and respects those with it. The primary example is his fellow Kumo jinchuriki, 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. Bee 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.
