Drake Pirates

The Drake Pirates are an infamous and notable rookie pirate crew discovered on the Sabaody Archipelago around the time the Straw Hat Pirates arrived there.

The crew ship is a marine battleship.

Crewmates
They resemble European fencers and swordsmen, reminiscent of the three musketeers.

Crew Strength
The crew is presumably strong because their captain is one of the Eleven Supernovas and a former Rear Admiral, which is the 4th highest position in the Marines. Another suggestion that the crew is strong is the fact that they made it all the way to Sabaody Archipelago, despite them being a "rookie" crew.
