Sabu

is an enka ninja music master. He apparently has a large raccoon named Ponta, as a pet. Killer Bee calls him and later the oddly constructed.

Appearance
Sabu is a short, middle aged man. His hair is done in a traditional Japanese manner, but with a punch perm bun on top of his head. He wields a very large axe.

Abilities
Sabu is shown to possess immense strength from the size of the axe that he wields. He is also highly observant as displayed when he witnessed the fight between Killer Bee and Kisame. Despite this, he has yet to display any specific jutsu.

Five Kage Summit arc
Sabu is introduced while teaching Killer Bee to show more passion in his singing. Kisame arrives during their practice to capture Killer Bee, and Ponta immediately charges at him. As soon as Ponta is defeated Sabu prepares to battle. Kisame runs towards him but is distracted by Killer Bee, giving Sabu a chance to strike. Killer Bee attacks too, but Kisame blocks both attacks with his Samehada, but obtains a minor injury in his left shoulder by one of Killer Bee's katana. When Killer Bee begins to transform, Sabu sees that Samehada is absorbing all of his chakra. Sabu stood back while Killer Bee continued his fight with Kisame. Seeing Killer Bee losing to Kisame, Sabu rushes to his aid only to see Kisame's decapitated head fall in front of him and that Killer Bee and his brother, the Fourth Raikage killed him.
