Kid Pirates

The Kid Pirates are an infamous and notable rookie pirate crew discovered on the Shabondy Archipelago around the time the Straw Hat Pirates arrived there. Like the Straw Hats, this crew has two bounties above one-hundred million belli, but both members have higher bounties than the respective members of the Straw Hat crew.

Pirate Flag
The flag used by the Kid Pirates differ from most other pirate flags in the way that it is somewhat of a smiley (something mainly seen, used by North Blue Pirates only) with a stitched together mouth.

Crewmates
The only thing significant of most, if not all, of the Kid Pirates is their heavy metal like appearance and the fact that many of them seems to wearing leather in one way or another.

Crew Strength
They are notable for the massive amount of damage left in their wake as they traveled through one of the other paths of the Grand Line towards the New World, causing a great lot of civilian casualties.

Furthermore, the entire crew easily survived the Haki released by Silvers Rayleigh, and they seem to be verry arrogant and confident in their skills. Although of that, they are still level minded.
