James Gordon Jr. in the context of "Jim Gordon (character)"

James W. "Jim" Gordon Sr. is a character appearing in American comic books published by DC Comics, most commonly in association with the superhero Batman. Created by Bill Finger and Bob Kane as an ally of Batman, the character debuted in the first panel of Detective Comics #27 (May 1939), Batman's first appearance, making him the first Batman supporting character ever to be introduced.

As the police commissioner of Gotham City, Gordon shares Batman's deep commitment to ridding the city of crime. The character is typically portrayed as having full trust in Batman and is even somewhat dependent on him. In many modern stories, he is somewhat skeptical of Batman's vigilante methods, but nevertheless believes that Gotham needs him. The two have a mutual respect and tacit friendship. Gordon is the biological or adoptive father (depending on the continuity) of Barbara Gordon, the second Batgirl and the information broker Oracle. Jim Gordon also has a biological son, James Gordon Jr., a psychopathic serial killer who first appeared in Batman: Year One (as an infant).

Barbara Joan Gordon is a superheroine appearing in American comic books published by DC Comics, commonly in association with the superhero Batman. The character was created by television producer William Dozier, editor Julius Schwartz, writer Gardner Fox, and artist Carmine Infantino. Dozier, the producer of the 1960s Batman television series, requested Schwartz to call for a new female counterpart to the superhero Batman that could be introduced into publication and the third season of the show simultaneously. The character subsequently made her first comic-book appearance as Batgirl in Detective Comics #359, titled "The Million Dollar Debut of Batgirl!" in January 1967, by Fox and Infantino, allowing her to be introduced into the television series, portrayed by actress Yvonne Craig, in the season 3 premiere "Enter Batgirl, Exit Penguin", in September that same year.

Barbara Gordon is the daughter of Gotham City police commissioner James Gordon, the sister of serial killer James Gordon Jr. and is initially employed as head of the Gotham City Public Library. Although the character appeared in various DC Comics publications, she was prominently featured in Batman Family which debuted in 1975, partnered with the original Robin, Dick Grayson, whom she has a history of working closely and being romantically involved with. In 1988, following the editorial retirement of the character's Batgirl persona in Batgirl Special #1, the graphic novel Batman: The Killing Joke depicts the Joker shooting her through the spinal cord in her civilian identity, resulting in paraplegia. In subsequent stories, the character was reestablished as a technical advisor, computer expert and information broker known as Oracle. Becoming a valuable asset providing intelligence and computer hacking services to assist other superheroes, she makes her first appearance as Oracle in Suicide Squad #23 (1989) and later became a featured lead of the Birds of Prey series. In 2011, as part of DC Comics The New 52 relaunch, Barbara recovered from her paralysis following a surgical procedure and returned as Batgirl. Barbara has since featured in the eponymous Batgirl monthly title as well as Birds of Prey and other Batman books. Following the events of Joker War, Barbara returned to her Oracle role while recovering from an injury, and continues to operate as both Batgirl and Oracle after the 2021 Infinite Frontier event.
