Info: Akatsuki has yet to find and seal two Jinchuuriki: Naruto and the Hachibi Bijuu named Kiraa Bii (Killer Bee). After Uchiha Madara swayed Sasuke to his side, he sent the young man after this Bijuu. Killer Bee posseses the ability to become his Bijuu, that of a tentacled ox beast. He was eventually knocked out by Sasuke's Amaterasu and taken for sealing. His body was revealed as a transformed tentacle, while the real Bee was still safe in Lightning. This allowed Bee to escape capture and evade Akatsuki.

Even though he has only been shown in one fight so far, Killer Bee has shown to be an extremely powerful ninja. He was easily capable of overwhelming the entire Team Taka, and has had his skill praised by several Kumogakure ninja, including his brother, the current Raikage.

His physical strength and taijutsu skill is immense. He is easily capable of disarming a skilled opponent with his bare hands, and proficiently wielded Suigetsu's huge sword seconds after picking it up. His defense is very strong as well, receiving a solid kick to the neck from Sasuke only to drop his sword and begin writing lyrics, and escaping unscathed after being shocked with Sasuke's Chidori and hit from behind with Jugo's rocket-augmented attack. His speciality, however, is wielding his seven swords, which he does in an odd way, holding them in between the joints of his arms and left leg, his stomach and the left side of his neck and in his mouth. As strange as it appears, he is quite skilled with this, spinning around like a buzz saw and overwhelming his opponent with all of the varying swings.

He is also capable of seamlessly releasing some of the swords to fight in a more conventional style, giving him great versatility. When he does find an opening, he can impale his opponent with most of his swords extremely quick all at once. Neither Suigetsu nor Sasuke could read his sword work, despite being a highly trained swordsman and having extreme mastery over the Sharingan.

During the battle with Sasuke he displayed the ability to flow lightning-elemental chakra through his blades to increase their cutting power, similar to the Chidori Current Sasuke uses with his Kusanagi Sword.

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; a technique called Lightning Plough Hot Sword. 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, he is able to become his tailed beast itself with great ease. With the form 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 Raikage.

The Eight-Tailed Giant Ox (八尾の巨牛, Hachibi no Kyogyū) is a demon ushi-oni sealed within Killer Bee of Kumogakure.
