Jack
Jack is a horned mink warrior and mammoth Zoan user who serves as one of Kaido's three Calamities and captain of the Mammoth in the Hundred Beast Pirates. He leads forces that attack islands and demand the handover of specific individuals while maintaining a one billion berry bounty displayed on his belt. Jack is known for prolonged assaults on Zou to locate Raizo and for later confrontations in Wano that involve direct clashes with mink leaders and samurai.
His actions connect to broader efforts by the Beast Pirates to retrieve allies and suppress resistance, including an attempt to destroy Zunesha after the Zou conflict. Jack survives multiple defeats and returns with reinforcements, demonstrating persistence in carrying out Kaido's objectives across the New World.
Appearance
Jack the Drought stands as a massive muscular figure with long curved tusks, wild hair, and a beaded necklace. He wears a spiked belt featuring a skull emblem and the text indicating his one billion berry bounty. His posture towers over smaller opponents during confrontations, with bared fangs and an intense glare visible in close views of his face.12

Personality
Jack issues single clear demands for the handover of Raizo while threatening the loss of peaceful lifestyles to those who resist. He mocks opponents by claiming no true warriors remain on an island and states that pity is troublesome because the dead do not seek revenge.45
Jack complains about returning to Zou with an annoyed and reluctant mood while scowling at the island. He expresses disbelief at reports that Raizo is absent and decides to kill the elephant Zunesha with ruthless determination after subordinates fail to provide acceptable answers.5
History
Jack first engages in broader New World matters when his death remains unconfirmed after attacking four ships escorting Doflamingo. His bounty stands at one billion berries during active conflicts in the area where he gets overpowered and thrown by Nekomamushi. These events mark early involvement in larger pirate alliances and responses to defeats like that of Caesar.67
After retreating from Zou Jack appears bandaged and resting inside a building there prompting shock from the minks at his survival. His forces then continue cannon bombardment on Zunesha as Duke Inuarashi orders mink ships to intercept. Transponder snail communication with Jack gets interrupted by sea conditions leading Kaidou to receive a report about lost contact.8910
