Jack the Drought

Overview

Jack the Drought is the first All-Star the audience encounters in One Piece, and his introduction through the ruins of Zou sets the tone for what Kaido’s inner circle represents: not simply powerful fighters but forces of destruction that leave permanent marks on the world. The devastation of the Mokomo Dukedom is presented as a historical event with real consequences for the Minks — not just a battle that happened and was resolved.

His bounty of over 4.6 billion berries places him among the highest confirmed bounties in the series and reflects a real-world assessment of how dangerous he is to encounter.

The Zou Zou no Mi, Model: Mammoth

Jack’s Ancient Zoan grants him access to a prehistoric megafauna — the woolly mammoth — at a scale that dwarfs modern elephant transformations. In full beast form, he becomes a massive mammoth capable of devastating charges, trunk strikes that demolish structures, and sustained physical assault that outlasts most opponents’ ability to keep fighting.

Ancient Zoan fruits are categorized separately from standard Zoans because they access species that no longer exist: the extinct creatures they transform users into are documented as having been physically superior to their modern equivalents. For Jack, this means his mammoth transformation represents power beyond what any living animal could provide.

He also demonstrated sufficient Haki to fight Mink rulers for five days straight — endurance that places him in a category where raw stamina is a weapon in itself.

The Attack on Zou

The Zou arc reveals Jack’s assault on the Mokomo Dukedom in retrospect, through accounts from the Minks. He arrived searching for Raizo, the ninja. When the Minks refused to reveal information about someone they claimed not to know (truthfully), Jack destroyed the city over five days.

The detail that distinguishes this assault is its duration. Jack was not executing a quick raid — he fought continuously against the Mink Tribe’s full strength, including their two kings, for five days. Neither Inuarashi nor Nekomamushi could stop him. The fact that Zunesha eventually defeated his fleet (by slamming a foot into it at Momonosuke’s command) is what finally ended the attack, not any failure on Jack’s part.

He survived even this — Jack was found alive after being submerged at sea, demonstrating a physical endurance that borders on unkillable.

Wano and Defeat

During the Onigashima Raid, Jack commanded Beast Pirate forces against the invading alliance. His encounter with the Akazaya Nine (Nine Red Scabbards) demonstrated his power against multiple high-level opponents simultaneously.

His final confrontation was with Inuarashi, who used his Sulong transformation — the Minks’ moon-powered enhancement — to fight on equal footing. Inuarashi won, ending Jack’s undefeated streak and avenging the destruction of Zou. The defeat was personal for the Minks and represented the liberation of Zou’s honor alongside Wano’s.

Significance

Jack establishes early in the Wano arc that Yonko crews have internal hierarchies of genuine catastrophic power. His existence answers the question of what it takes to devastate an entire civilization — the answer being a single subordinate operating without his captain’s full attention. The implication for Kaido himself is appropriately terrifying.
