The Black Hole Gang constituted a group of pirates whose base of operations was the Delphon system, and they were known for their acts of terror against the shipping lanes within the Anoat sector. Initially established and commanded by Hethra Mcgrrrr, a Corellian, under the moniker Mcgrrrr Gang, the group experienced frequent changes in leadership because of intense internal conflicts. Nevertheless, when the gang encountered challenging periods, the former captain, Mcgrrrr, would consistently reappear to assist in restructuring the crew before going back to a state of partial retirement.
During a certain period when the Galactic Empire was at its peak, the Black Hole Gang found itself under the leadership of Cru Devilar, a Pantoran, who made use of several Trandoshan henchmen. Cage, a Mikkian technology dealer hailing from Delphon City, maintained connections with the gang.
In the era of the Empire's Iron Blockade, the criminal organization known as the Trade Spine League was compelled to negotiate with the Black Hole Gang whenever they sought to discreetly transport a consignment of crystals from the planet Burnin Konn to the planet Delphon.
