Riddler in the context of "Domino mask"

Batman is a superhero who appears in American comic books published by DC Comics. Batman was created by artist Bob Kane and writer Bill Finger, and debuted in the 27th issue of the comic book Detective Comics on March 30, 1939. In the DC Universe, Batman is the alias of Bruce Wayne, a wealthy American playboy, philanthropist, and industrialist who resides in the fictional Gotham City. His origin story features him swearing vengeance against criminals after witnessing the murder of his parents, Thomas and Martha, as a child, a vendetta tempered by the ideal of justice. He trains himself physically and intellectually, crafts a bat-inspired persona, and monitors the Gotham streets at night. Kane, Finger, and other creators accompanied Batman with supporting characters, including his sidekicks Robin and Batgirl; allies Alfred Pennyworth and James Gordon; love interest and occasional adversary Catwoman; as well as foes such as the Penguin, the Riddler, Two-Face, and his archenemy, the Joker.

Kane conceived Batman in early 1939 to capitalize on the popularity of Superman; although Kane frequently claimed sole creation credit, Finger substantially developed the concept from a generic superhero into something more bat-like. They drew inspiration from pulp fiction characters like the Shadow, Sherlock Holmes, and the Green Hornet. Batman received a spin-off publication, Batman, in 1940. Kane and Finger introduced Batman as a ruthless vigilante who frequently killed or maimed criminals, but he evolved into a just, tempered superhero with a stringent moral code that prohibits killing during the 1940s. Unlike most superheroes, Batman does not possess any superpowers, instead relying on his intellect, fighting skills, and wealth. The 1960s Batman television series used a camp aesthetic, which continued to be associated with Batman for years after it ended. Various creators worked to return Batman to his darker roots in the 1970s and 1980s, culminating with the 1986 miniseries The Dark Knight Returns by Frank Miller.

The Batman family enemies are a collection of supervillains appearing in American comic books published by DC Comics. These characters are depicted as adversaries of the superhero Batman and his allies.

Since Batman first appeared in Detective Comics #27 (May 1939), his supporting cast has expanded to include other superheroes, and has become what is now called the "Bat-family". As with most superheroes, a cast of recurring enemies to the Batman family have been introduced throughout the years, collectively referred to as Batman's "rogues gallery". Many characters from Batman's rogues gallery who are criminally insane become patients at Arkham Asylum after they are apprehended.

A supervillain, supervillainess or supercriminal is a variant of the villainous stock character who possesses superpowers. The character type is sometimes found in comic books and is often the primary adversary of a superhero in the same story.

The Batman is a 2022 American superhero film based on the DC Comics character Batman. Directed by Matt Reeves from a screenplay he wrote with Peter Craig, it is a reboot of the Batman film franchise. Robert Pattinson stars as Bruce Wayne / Batman alongside Zoë Kravitz, Paul Dano, Jeffrey Wright, John Turturro, Peter Sarsgaard, Andy Serkis, and Colin Farrell. The film sees Batman, in his second year fighting crime in Gotham City, uncover corruption with ties to his own family while pursuing the Riddler (Dano), a mysterious serial killer targeting the city's elite. Reeves and Dylan Clark produced the film for DC Films and Warner Bros. Pictures.

A Batman film for the DC Extended Universe (DCEU) franchise was announced in October 2014, with Ben Affleck starring as the character. He signed on to also direct, produce, and co-write The Batman by 2016, but had reservations about the project and stepped down in January 2017. Reeves took over the following month and reworked the story, removing the DCEU connections to focus on a younger version of the character earlier in his vigilante career compared to Affleck's portrayal. Reeves worked on the script with Craig and Mattson Tomlin, and sought to explore Batman's detective aspects more than previous films, drawing inspiration from the films of Alfred Hitchcock and the New Hollywood era, and comics such as "Year One" (1987), The Long Halloween (1996–97), and Ego (2000).

Richard W. Sprang (July 28, 1915 – May 10, 2000) was an American comic book artist and penciller, best known for his work on the superhero Batman during the period fans and historians call Golden Age of Comic Books. Sprang was responsible for the 1950 redesign of the Batmobile and the original design of the Riddler, who has appeared in film, television and other media adaptations. Sprang's Batman was notable for his square chin, expressive face and barrel chest.

Sprang was also a notable explorer in Arizona, Utah, and Colorado, whose discoveries included "Defiance House", a previously unrecorded ancestral Puebloan structure. Sprang's voluminous correspondence, journals, and thousands of photographs are archived at Northern Arizona Universities Cline Library Special Collections in Flagstaff, Arizona. A small amount of material is at the Utah Historical Society in Salt Lake City, Utah.
