Zanki belongs to the Numbers, the band of artificial giants in the service of the Beasts Pirates, and he stands for the figure three. Born of failed cloning experiments and later bought by Kaidou, he took part in the Onigashima battle during the Wano conflict.
The experiments forced on his body left Zanki towering even over an ordinary giant. His head bears two thin horns that point straight out to the sides, and his mouth is crowded with sharp teeth. The face is oval, fronted by a small nose angled downward, flushed cheeks, and a dense dark goatee, while a heavy brow droops to lend him a forever-mournful cast. His body is round, the limbs by contrast rather thin. Marked onto his right side is the formal kanji standing for three.
His attire is plain: a dark kabuto, a braided shimenawa cord looped around his neck like a necklace, and a dark wrap covering his legs. A dark metallic guard wraps his left wrist, a sash at his waist holds a tucked-away katana, and his feet rest in simple wooden geta.
Loyalty to the Beasts Pirates runs deep in Zanki, and he carries out Scratchmen Apoo's orders faithfully. In keeping with every member of the Numbers, his name feeds his own peculiar laugh, written out as Zakikikiki.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...
His nature as an artificial ancient giant makes Zanki immensely strong, to the point that he can tear a building's roof loose with just one hand. A katana rests at his hip, yet he has yet to demonstrate any combat skill with the weapon.
His beginnings trace back to a Punk Hazard program that set out to recreate the giants of old by artificial means. Judged a failure, Zanki and the rest of the test subjects were later bought up by Kaidou and shipped to Onigashima, where the group earned the name the Numbers. With the Fire Festival five days out, they landed at Hakumai by way of Mogura Harbor and made for Onigashima in Apoo's company. Once war erupted there, Zanki ate and drank with the fellow Numbers Inbi and Fuga rather than fighting, until Apoo and X Drake joined them in the chamber. He went on to face CP0 and was beaten by Maha.
