Trump Pirates

The Trump Siblings are a group of animal/card themed captains, with Bear King being the leader of the crew. They appeared in the second One Piece Movie. Each captain commanded several pirate ships that are adorned with card symbols and animal figureheads suited to their personal effects.

Part in the Story
The siblings ruled over Clockwork Island for years in their headquarters, the Trump Castle, and forcing the scientists to build a cannon for which they could use make their leader into the Pirate King (an obvious exaggeration on how they think a mere weapon could conquer the pirate world). Eventually, the entire crew were defeated by the Straw Hat Pirates.

Crew Strength
The overall crew strength seems to be rather weak, despite having five bounties, two Devil Fruit users, and each commanding several crews of pirates (which it a large group altogether, similar to Don Krieg's Pirate Armada). Three of the captains, Boo Jack, Skunk One, and Pin Joker were quickly defeated. Honey Queen, despite holding a Logia-class Devil Fruit, was easily captured. The overall leader, Bear King, was the only one who put up a longer fight, but was regardless killed.
