Harvey Bullock is a Detective in the Gotham City Police Department working underneath James Gordon. His rough slovenly demeanor and willingness to do what it takes have given him a mean reputation, although he's one of the few honest cops on the force. Because of his position he often works alongside Batman, although their relationship began as adversarial. This has evolved into a begrudging mutual respect. He has also been a member of Checkmate.
"Lt. Bullock" was created by Archie Goodwin and Howard Chaykin, first appearing in Detective Comics #441. (1974) Harvey Bullock was further developed by Doug Moench and Don Newton when they re-introduced the character and cemented his legacy in the Batman mythos in Batman #361. (1983)
