One Piece Wiki

Zanki is a member of the Numbers in the Beasts Pirates, representing the number "three".[2]


Due to the experiments conducted on him Zanki is far taller than even normal giants, and has a pair of slender, straight, outward-pointing horns, along with a mouth full of sharp teeth. He has a round body with slender arms. He has an oval-shaped face with a small downward-pointed nose, red cheeks and a bushy dark-colored goatee. He has a prominent brow-ridge, which is often seen sloped downward in a sad-looking expression. The kanji "参", which stands for the number 3, is tattooed on his right side. He wears a plain-looking dark-colored kabuto helmet, a braided Shimenawa rope as a necklace, and a dark garment on his lower body. On his left wrist Zanki seemingly wears some sort of dark, metallic bracelet or gauntlet.


Like the other Numbers, Zanki possesses a unique laugh which plays off his name: "Zakikikiki".[2]

Abilities and Powers

As an artificial ancient giant, he is tremendously powerful[2] and can tear the roof off of a building with one hand.[1]



Sometime in the past, Zanki was part of an experiment on Punk Hazard that attempted to artificially recreate the ancient giants. The experiment was deemed a failure, and Zanki and his fellow test subjects were eventually bought by Kaidou, becoming known as the Numbers and residing on Onigashima.[3]

Wano Country Arc

Five days before the Fire Festival, the Numbers arrived in Hakumai via Mogura Harbor and headed toward Onigashima with Scratchmen Apoo.[4]

Zanki and fellow Numbers Inbi and Fuga were eating and drinking in a Skull Dome chamber together, and were not participating in the war that broke out between the Beasts Pirates and Ninja-Pirate-Mink-Samurai Alliance. They were eventually joined in the room by Apoo and X Drake.[2] Zanki sat while Apoo and Drake fought. After Yamato passed through the room, Apoo chased after her and ordered Zanki and Inbi to follow him.[5]


  • Zanki's name contains the kanji for "three" ( zan?) and the kanji for "oni" (?)
  • The shape of Zanki's brow-line resembles the Arabic numeral used to represent the number three, the character's namesake.
