Gillian B. Loeb was the fictitious Gotham City police commissioner in the DC Multiverse in the story arc, Batman: Year One.
He was ranked above Detective Jim Gordon and his partner, Flass. He was thoroughly corrupt and found Gordon's honesty and heroic behaviour most troubling for his operation. However, he did not immediately share the same opinion about the mysterious vigilante, Batman since he thought the character was targetting only low level criminals which he thought was politically advantageous. However, Batman attacked his residence during a dinner party with his criminal and political contacts and publicly announced that he fully intended to bring them down as well.
With that threat, Loeb ordered Gordon to arrest Batman immediately. However, the vigilante proved frustratingly elusive until a impromptu rescue on the street led to him being cornered in an abandoned building. Although the situation seemed hopeless with the police surrounding the building, the commissioner ordered a bomb dropped on and a SWAT conducting an armed search of the rubble, Batman still escaped much to Loeb's aggravation.
Eventually, Batman's investigations, Gordon's resistance to Loeb's attempts to cow him and District Attorney Harvey Dent's prosecution of Flass who divulged damaginng evidence force Loeb to resign.
Commissioner Loeb appears Batman Begins, played by English actor Colin McFarlane. The character is african american and there is no indication that he is corrupt.
