Boo Jack

Boo Jack is a portly man dressed head to toe in pig motifs. A bandanna-style cap shaped like a pig's head sits atop him, and he sports a yellow shirt stamped with the letter J along with suspenders. His torso is wrapped in furred white Toge Toge Armor, and matching furred bands ring his arms and elbows.

Every bit as vicious as his siblings, Boo Jack is a conceited servant of Bear King who delights in exploiting unfair odds and taunting those he judges beneath him, a smugness that helped bring about the thrashing Sanji handed him. He occasionally slips into the manner of a quiz-show emcee, fitting since boo doubles as Japan's buzzer for a wrong answer, grilling enemies on the identity of the future Pirate King; his own reply is forever Bear King, whereas Luffy forever names himself.

Boo Jack swims capably, enough that Honey Queen could balance on his back as he drifted in the water, and his bounty of 3,200,000 Berries marks him as a genuine danger. His main weapon, the Toge Toge Armor, projects or fires spikes and folds him into a giant rolling spiked sphere. He further lobs white orbs that either burst like bombs or scatter spikes. In Clockwork Island Adventure, he and Honey Queen confronted the Straw Hats together with the Thief Brothers, denied taking the Going Merry, then ordered an assault. Shadowing the crew afterward, they bombed the Thief Brothers' vessel and seized Nami as a present for Bear King. Boo Jack later punctured the heroes' hot-air balloon, helped capture Sanji, and following Luffy's explosive arrival rushed at Nami, only for Sanji to intercept and pummel him. His ultimate fate is uncertain, since he lay senseless as the island fell apart.
