Alfred Pennyworth in the context of "Batman"

The Batman supporting characters are fictional characters that appear in the American comic books published by DC Comics featuring the superhero Batman as the main protagonist.

"Batman family" or "Bat-Family" is the informal term for Batman's closest allies, who are mainly masked vigilantes operating in Gotham City. Since the Bat-Family's introduction in 1939, Batman has accumulated a number of recognized supporting characters. The first Batman supporting character was Commissioner James "Jim" Gordon, Batman's ally in the Gotham City Police Department, who first appeared with Batman in Detective Comics #27 (May 1939). Some of the other allies of Batman include his vigilante partner, Robin, who was introduced in 1940; his butler, Alfred Pennyworth, who was introduced in 1943; and Barbara Gordon, who was introduced in 1967.

Pennyworth, marketed as Pennyworth: The Origin of Batman's Butler for its third season, is an American television series that premiered on July 28, 2019, on Epix, based on DC Comics' Batman character of the same name. The series was developed for television and is executive produced by Bruno Heller and Danny Cannon, and stars Jack Bannon as Alfred Pennyworth, a younger version of the iteration of the character previously portrayed by Sean Pertwee in Heller's and Cannon's Fox series Gotham (2014–2019), with the series serving as a prequel to both Gotham and V for Vendetta, by Alan Moore, David Lloyd, and Tony Weare. Ben Aldridge, Hainsley Lloyd Bennett, Ryan Fletcher, Dorothy Atkinson, Emma Paetz, Paloma Faith, Polly Walker, James Purefoy, and Jason Flemyng also star.

In October 2021, it was announced that the series would premiere on HBO Max for its third season, although it would still continue to air on Epix in addition.

Richard John "Dick" Grayson is a superhero appearing in American comic books published by DC Comics, commonly in association with Batman, the Teen Titans, and the Justice League. Created by writer Bill Finger and artist Bob Kane, he first appeared in Detective Comics #38 in April 1940. Dick is the original and most popular incarnation of Robin, Batman's crime-fighting partner – together known as the Dynamic Duo. In his origin story, he is the orphaned son of master acrobats the Flying Graysons who is later adopted by Batman's alter ego Bruce Wayne.

Dick Grayson has undergone significant character development since originally introduced in 1940. In 1984, he graduated from the role of Robin to become the adult superhero Nightwing, protector of the city of Blüdhaven, Gotham City's economically troubled neighbouring city. Since then, as Bruce's eldest son, Dick has taken on an older brother figure to his male successors as Robin – tearaway Jason Todd, teenage prodigy Tim Drake, and trained assassin Damian Wayne, who is also Batman's biological child. Among other members of the Batman Family, his closest relationships are with Batman's loyal butler and father figure Alfred Pennyworth, and with his romantic interest Barbara Gordon, who served as Batgirl alongside Dick as Robin, and who later aids Nightwing as Oracle. Dick has also taken up the mantle of Batman himself on a number of occasions when Bruce was missing, incapacitated, or believed dead.
