Harvey Bullock is a cop in the GCPD, who served alongside James Gordon.

Batman's Profile on Harvey Bullock
''Bullock is typical of most of the GCPD officers - he's on the take, and uses his position of authority to his advantage. However, careful examination of his record and recent activities suggests he does follow the law when dealing with civilians. Perhaps theres hope yet for Harvey. With the right motivation and direction, he could turn out to be a good cop, but for now he should be considered just as dirty as any other GCPD officer.''

Harvey Bullock, similar to other GCPD officers under Commissioner Loeb, was on the take for various criminal organizations. At one point, Loeb, under the influence of Black Mask, had Bullock placed as the partner of then-Sergeant James Gordon to see if he could uncover any blackmail material (as well as given the implied suggestion of arranging a honeypot trap for Gordon). Bullock was skeptical about it working, due to knowing that Gordon does not trust him.

When Batman was discovered at Blackgate in the aftermath of a prison riot at the prison orchestrated by Black Mask (resulting in the execution of Commissioner Loeb instead of Julian Day) on Christmas Eve, Bullock, alongside Gordon, tried to apprehend him, but Batman managed to escape via the Batplane. After Batman's departure, Bullock then sarcastically commented "No such thing as a Bat Man, huh?", alluding to Gordon's public denials about the rumors about Batman's involvement in ensuring the GCPD arrested criminals.

Later, after Batman managed to subdue The Joker at the Gotham Royal Hotel and left him to be arrested by the GCPD, Bullock, when arresting the madman, demanded to know where Batman was headed under the belief that the Joker was his employer, pointing out that it was the only reason he could think of that the masked vigilante would "risk [Batman's] life to save [The Joker's] sorry ass" (referring to Batman jumping after the Joker after the latter was thrown off the roof of the hotel by an explosion).
