Bonney Pirates

The Bonney Pirates (ボニー賊団) are an infamous and notable rookie pirate crew discovered on the Sabaody Archipelago around the time the Straw Hat Pirates arrived there.

Crewmates
Most crewmembers are seen wearing undersized clothing like their captain, most notedly small singlets and sweatshirts, presumably so their clothes will still fit if they were transformed into children. At least one of the crewmembers is seen wearing a chef's hat and two have French-style moustaches, which may pertain as a theme to Jewelry Bonney's insatiable hunger and compulsive eating habits.

Crew Strength
It can be presumed that they are strong because of their captain's high bounty and the fact that they made it all the way to Sabaody Archipelago.
