James Gordon is the Commissioner of the Gotham City Police Department, and one of Batman's greatest allies. He is a controversial political figure in Gotham City because of his willingness to work alongside a vigilante, but he is one of the most honest cops on the force, often struggling against corruption from within. He frequently works outside the law when necessary, although he maintains a strict unbreakable moral code. He has made it clear many times that he only tolerates Batman because they follow the same code, and if he ever crossed the line Gordon would not hesitate to bring him down. They share many rooftop meetings on top of Gotham City Police Headquarters going over cases, with Gordon supplying information to the dark knight. He contacts Batman for their regular meetings using the Bat-Signal, a spotlight that shines a bright bat symbol into the night skies. His niece or sometimes daughter is Barbara Gordon, better known as Batgirl. His son was originally shown to be Tony Gordon, but was changed to James Gordon, Jr. during Year One in Post-Crisis continuity. Commissioner Gordon was created by Bob Kane and Bill Finger, first appearing in Detective Comics #27 (1939).
