Sabu

is an enka ninja music master. Killer B calls him and later the oddly constructed. In the anime, Sabu's name was changed to for unknown reasons.

Appearance
Sabu is a short, middle aged man. He wears a cream-coloured robe adorned with a purple belt and two purple fuzzy balls hanging in the front. He also appears to wear a purple garment underneath the robe and has a mesh shirt under his robe as well. He has dark brown hair which 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 great strength, as he wields an enormous axe with ease. He is also highly observant as displayed when he witnessed the fight between Killer B and Kisame Hoshigaki.

Five Kage Summit Arc
Sabu is introduced while teaching Killer B to show more passion in his singing. Kisame arrives during their practice to capture Killer B, 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 B, giving Sabu a chance to strike. Killer B attacks too, but Kisame blocks both attacks with his Samehada, but obtains a minor injury in his left shoulder by one of Killer B's katana. When Killer B begins to transform, Sabu sees that Samehada is absorbing all of his chakra. Sabu stood back while Killer B continued his fight with Kisame. Seeing Killer B losing to Kisame, Sabu rushes to his aid only to see Kisame's decapitated head fall in front of him and that Killer B and his brother had killed him (in the anime, Sabu was instead next to the Kumo-nin, and Kisame's head was not shown landing next to him), though it was later discovered to be Zetsu instead.
