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.
The "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.[1]
Batman also forms bonds and close working relationships with other superheroes, including Justice League members such as Superman, Green Arrow, Zatanna and Wonder Woman, as well as members of the Outsiders superhero team. Others such as Jason Bard, Harold, Onyx, and Toyman work for him.
In addition, Batman has a collection of adversaries in fiction that is commonly referred to as Batman's rogues gallery. The rogues gallery includes the Joker, the Penguin, and the Riddler, among others. He also has several love interests, including Catwoman, Talia al Ghul, Silver St. Cloud, Poison Ivy, and Julie Madison.
