The Eight-Tailed Beast is currently one of the two remaining Tailed Beasts that were not extracted by Akatsuki, the other one being the Nine-Tailed Demon Fox. The Jinchūriki is a black, musclebound Cloud shinobi, who appears to dislike light. On his right shoulder, he has a tattoo that says "iron"; and on his left cheek, he has a tattoo of a bull's horn. He also carries seven swords. It also seems that he hates being called the host for the Eight-Tailed Beast, and prefers to be referred as "me and that thing". Killer Bee appears to be a physically strong man as he was able to wield Suigetsu's sword with great ease and was also able to take down Jugo during his curse seal stage.

Abilities
Most of his abilities are still yet unknown, but it has been shown that he uses eight swords in a very peculiar manor. He places two swords in his hand, two on his elbows, two in his knees, one on his neck and the last in his mouth. This special maneuver allows him to attack his opponent with great speed and also in a circular faction, like a ball. Also, he is able to put chakra into his blades allowing them to up their power and also re transfer any other chakra being propelled by the opponent.

Speculation
As most of the other Tailed Beasts seen so far are based upon mythological creatures, it was speculated that this Tailed Beast was based upon the eight-headed and eight-tailed serpent, Yamata no Orochi. But from the shadow when Sasuke goes to retrieve the beast, it seems to be an octopus. Some fans believed that Orochimaru was the Eight-Tailed Beast due to his snake-like abilities, however, this was proven false in chapter 408.
