The Black Petrel Pirates (クロ ウミツバメ 海賊団, Kuro Umitsubame Kaizokudan) are a pirate crew under a year old, yet their strength and ferocity are already well known in government bases throughout the grand line. Their captain is the ruthless Hayward D. Rockefeller, an oil-man who ate the Seki Seki no Mi, and the only reason that Hayward is not one of the Supernovas is that his parents, of Noble lineage, persuaded the government to lower his bounty so as not to call a great deal of attention to him. The name of the crew is a pun based on Hayward's power, as their insignia of a black petrel (a seabird) is a homophone of petrol, a byproduct of petroleum.
