Killer B

The Eight-Tails Jinchuuriki is a ninja from Kumogakure and the host of the Eight-Tailed Beast. He 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.

Personality
It seems that he looks highly of himself, and prefers to be referred as Mr. Host or Mr. Eight-Tails by all people. He also appears willing to speak in song more specifically in rap style, even when confronted with potential threats.

Hunt for the Eight Tails
Team Hawk, after discovering that the Eight Tails was training in the Unraikyo Mountains traveled up the mountain. The Eight-Tails revealed himself after appearing to contain his tailed beast. When Suigetsu attacked him, he easily overpowered him, and uses Suigetsu's sword to defeat Jugo afterwards. He later shows an unorthodox sword style where he manages to hold all seven of his swords in a rather awkward pose, this is deceiving as his Seven sword style is extremely formidable and he wounds Sasuke.

Abilities
He appears to be able to control the power of his tailed beast with great ease, similar to his fellow Cloud shinobi, Yugito Nii.

He wields seven swords 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. However he also seems to be quite skilled with this, being able spin around like a buzzsaw, and even completely impale his opponent with most of his swords

During the battle with Sasuke he displayed the ability, like Sasuke, to conduct Chakra down his blade to increase its cutting power like Chidori Current does with Sasuke's Kusanagi.

Trivia

 * His Sword style is reminiscent of | Roronoa Zoro's | Santōryū in One Piece, a fellow Shonen Jump manga.
