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
Much of her crew wear greatly undersized clothing like their captain, presumable so their clothes will still fit if they were transformed into children.

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