Killer B

A shinobi from Kumogakure as well as one of the greatest brother characters in anime, Killer B. The most recent jinchriki of the Eight-Tails, Gyki, was able to become friends with it and harness its strength for Kumo, unlike his predecessors. B wants to be the best rapper in the world despite being in charge of the village's security. Killer B is a skilled swordsman and the jinchuriki of the Eight-Tails. His ability with a sword allowed him to defeat Sasuke Uchiha, demonstrating his superior fighting skills.

Killer B became a fan favorite because of his colorful persona and love of rapping. The Third Raikage adopted Killer B, making him Lightning A's sibling. The two became an incredible team and even co-developed unique fighting techniques.

Regardless of his position and upbringing as a jinchuriki, Killer B is highly proud of his own power and, consequently, of who he is. B really wanted a vacation and was even prepared to fake his imprisonment for one because he was imprisoned in the hamlet very soon after his brother entered government and was named the village's guardian. Killer B, however, has no qualms about risking his life in order to save a loved one when they are in danger.
