Boo Jack

Boo Jack appears in the second movie, Clockwork Island Adventure. He is one of the Trump Siblings Pirates.

Appearance
Boo Jack is a fat man with a pig-themed outfit. He wears a bandanna-like hat with a pig's head design, a yellow shirt with a "J" on the front, as well as suspenders, and a white furred-back that is his Toge Toge Armor. He also has furred arm- and elbow-bands.

Personality
Boo Jack enjoys asking riddles. He asks a few riddles about who will be the Pirate King ("Bear King" is the answer to all of them). Each time, Monkey D. Luffy answers "himself".

Boo Jack also seems quite arrogant, as he mocks Sanji that even with the recovered shoes, there is nothing he could do to win (which he is wrong).

Weapons
Boo Jack fights with a weapon called the Toge Toge no Yoroi (トゲトゲの鎧 Spike Spike Armor), with which he can emit spikes on his coat and launch them at people. He can also become a giant, rolling, spiked ball.

He also has white balls that he can throw at his opponents, which either explode like bombs or emits spikes.

History
Boo Jack first appears with Honey Queen to kidnap Nami from the rest of the Straw Hat Pirates. Sanji found himself at a disadvantage against him as he couldn't attack properly in his bare feet (his shoes were stolen with the Going Merry). Once Sanji gets his shoes back, however, he easily beats Boo Jack into submission.

Trivia

 * Every member of Bear King's crew has animal and card based themes. Boo Jack was based on a Pig and the Jack. The similar noise "Buu" is the sound a pig makes in Japanese ("Oink" to an English speaker).
 * His Toge Toge Armor is similar to Miss Doublefinger's Toge Toge no Mi powers.
