Robin (character) in the context of "Sidekick"

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.

Martha Wayne (née Kane) is a fictional character appearing in American comic books published by DC Comics. She is the mother of Bruce Wayne (Batman), and wife of Dr. Thomas Wayne as well as the paternal grandmother of Damian Wayne, the fifth Robin. After she and her husband are murdered in a street robbery, her son—orphaned—is inspired to fight crime by adopting the vigilante identity of the Batman.

As a key figure in Batman's origin story, Martha Wayne has appeared in multiple forms of media. Notable portrayals of the character in live-action include Sara Stewart in Batman Begins, Lauren Cohan in Batman v Superman: Dawn of Justice, Carrie Louise Putrello in Joker, and Stella Stocker in The Batman. Emma Paetz also portrays her in the television series Pennyworth in a main role.

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.

Batgirl is the name of several superheroines appearing in American comic books published by DC Comics, depicted as female counterparts and allies to the superhero Batman. The character Betty Kane was introduced into publication in 1961 by Bill Finger and Sheldon Moldoff as Bat-Girl, and was replaced in 1967 by Barbara Gordon, who became the most iconic Batgirl. The character debuted in Detective Comics #359 (January 1967) by writer Gardner Fox and artist Carmine Infantino, introduced as the niece/adoptive daughter of police commissioner James Gordon.

Batgirl operates in Gotham City, allying herself with Batman and the original Robin, Dick Grayson, along with other masked vigilantes. The character appeared regularly in Detective Comics, Batman Family, and several other books produced by DC until 1988. That year, Barbara Gordon appeared in Barbara Kesel's Batgirl Special #1, in which she retires from crime-fighting. She subsequently appeared in Alan Moore's graphic novel Batman: The Killing Joke where, in her civilian identity, she is shot by the Joker and left paraplegic. Although she is reimagined as the computer expert and information broker Oracle by editor Kim Yale and writer John Ostrander the following year, her paralysis sparked debate about the portrayal of women in comics, particularly violence depicted toward female characters.

The Joker is a supervillain appearing in American comic books published by DC Comics. Created by Bill Finger, Bob Kane, and Jerry Robinson, the character first appeared in the debut issue of the comic book Batman on April 25, 1940. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for his design while acknowledging Finger's writing contribution. Although the Joker was planned to be killed off during his initial appearance, he was spared by editorial intervention, allowing the character to endure as the archenemy of the superhero Batman.

In the DC Universe, the Joker is portrayed as a criminal mastermind and the antithesis of Batman in personality and appearance. He was introduced as a murderous psychopath with a warped, sadistic sense of humor but became a comical prankster in the late 1950s in response to regulation by the Comics Code Authority, before returning to his darker roots during the early 1970s. The Joker has been part of defining Batman stories, including the murder of Jason Todd—the second Robin and Batman's ward—in "A Death in the Family" (1988) and the paralysis of Barbara Gordon—the first Batgirl—in The Killing Joke (1988). Unlike many comic book characters, the Joker does not have a definitive origin story, but various possible ones have been developed. The most common story involves him falling into a tank of chemical waste that bleaches his skin white, turns his hair green and lips red, and leaves him with a rictus grin; the resulting disfigurement drives him insane.

Batman is an ongoing superhero comic book series published by DC Comics, featuring the character of the same name as its protagonist. The character, created by Bill Finger and Bob Kane, first appeared in Detective Comics #27 (cover dated May 1939). Batman proved to be so popular that a self-titled ongoing comic book series began publication with a cover date of spring 1940. It was first advertised in early April 1940, one month after the first appearance of his new sidekick, Robin the Boy Wonder. Batman comics have proven to be popular since the 1940s.

Though the Batman comic book was launched as a quarterly publication, it later became a bimonthly series through the late 1950s, after which it became a monthly publication.

Batman is an American live-action television series based on the DC Comics character of the same name. It stars Adam West as Bruce Wayne/Batman and Burt Ward as Dick Grayson/Robin—two crime-fighting heroes who defend Gotham City from a variety of archvillains. It is known for its camp style and upbeat theme music, as well as its intentionally humorous, simplistic morality aimed at its preteen audience. The 120 episodes aired on the ABC network for three seasons from January 12, 1966, to March 14, 1968, twice weekly during the first two seasons, and weekly for the third. A companion feature film was released in 1966 between the first and second seasons of the TV show.

Batman held the record for the longest-running live-action superhero television series (in terms of episodes) until it was surpassed by Smallville in 2007.

All Star Batman & Robin, the Boy Wonder is an American comic book series written by Frank Miller and penciled by Jim Lee. It was published by DC Comics, with a sporadic schedule, between 2005 and 2008. The series was to be rebooted under the title Dark Knight: Boy Wonder in 2011, when both Miller and Lee were to finish the last six issues. The series retells the origin story of Dick Grayson, who became Batman's sidekick Robin.

This was the first series to be launched in 2005 under DC's All Star imprint. These series are helmed by renowned writers and artists in the American comic book industry and attempt to retell some of the history of prominent DC Universe characters, but outside of DC Universe continuity, and not be restricted by it, in order to appeal to new and returning readers. Each title under the All Star imprint is set in its own continuity and separate universe. According to Miller, the series takes place in the same continuity as Miller's other Batman-related works, such as The Dark Knight Returns.

Damian Wayne (né al Ghul) is a superhero appearing in American comic books published by DC Comics, commonly in association with Batman. He was created by Grant Morrison and Andy Kubert. Damian Wayne is the biological son of Bruce Wayne/Batman. His mother is Batman's love interest Talia, daughter of Batman's adversary Ra's al Ghul, who wants Bruce Wayne to sire his future lineage. Talia calls off their marriage once she falls pregnant and tells Bruce she miscarried, keeping Damian's existence hidden until Batman #656 (2006). Damian was intended to kill and replace Batman and serve as a host body for Ra's al Ghul, which would unify the Wayne and al Ghul factions. Damian is Bruce's youngest child and only biological one, with Dick Grayson, Jason Todd, Tim Drake, and Cassandra Cain as his adopted siblings.

A prototype of the character originally appeared as an unnamed infant in the 1987 story Batman: Son of the Demon, which at the time was not considered canon. Following this, various alternate universe stories dealt with the character's life, giving him various names. In 2006, the character was reinterpreted as Damian Wayne by Grant Morrison, and introduced into the main continuity in Batman #655, the first issue of the "Batman and Son" story arc. Damian Wayne is the fifth character to assume the role of Robin, Batman's vigilante partner.
