Dick Grayson in the context of "Teen Titans"

Robin is the alias of several superheroes appearing in American comic books published by DC Comics. The character was created by Bob Kane, Bill Finger, and Jerry Robinson to serve as a junior counterpart and the sidekick to the superhero Batman. As a team, Batman and Robin have commonly been referred to as the Caped Crusaders and the Dynamic Duo. The character's first incarnation, Dick Grayson, debuted in Detective Comics #38 (April 1940). Conceived as a way to attract young readership, Robin garnered overwhelmingly positive critical reception, doubling the sales of the Batman titles. Robin's early adventures included Star Spangled Comics #65–130 (1947–1952), the character's first solo feature. He made regular appearances in Batman-related comic books and other DC Comics publications from 1940 through the early 1980s, until the character set aside the Robin identity and became the independent superhero Nightwing.

The character's second incarnation, Jason Todd, first appeared in Batman #357 (1983). He made regular appearances in Batman-related comic books until 1988, when he was murdered by the Joker in the storyline "A Death in the Family". Jason was resurrected following a reality-changing incident, eventually becoming the Red Hood. The premiere Robin limited series was published in 1991, featuring the character's third incarnation, Tim Drake, training to earn the role of Batman's vigilante partner. After two successful sequels, the monthly Robin series began in 1993 and ended in early 2009, which also helped his transition from sidekick to a superhero in his own right. In 2004 storylines, established DC Comics character Stephanie Brown became the fourth Robin for a short time before the role reverted to Tim Drake. Damian Wayne succeeds Drake as Robin in the 2009 story arc "Battle for the Cowl."

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.

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.

The Golden Age of Comic Books describes an era in the history of American comic books from 1938 to 1956. During this time, modern comic books were first published and rapidly increased in popularity. The superhero archetype was created and many well-known characters were introduced, including Superman, Batman, Robin, Captain Marvel, Captain America, and Wonder Woman.

Deathstroke is a supervillain appearing in American comic books published by DC Comics. Created by writer Marv Wolfman and artist George Pérez, the character first appeared in The New Teen Titans #2 (1980) as Deathstroke the Terminator.

Deathstroke is the alias of Slade Joseph Wilson, a mercenary and former U.S. Army operative who gains enhanced physical and mental abilities from an experimental super-soldier serum. Regarded as the greatest and deadliest assassin in the DC Universe, he serves as the archenemy of Dick Grayson and the Teen Titans, although he has also fought other superheroes, including Batman, Green Arrow, and the Justice League. Deathstroke's vendetta against the Titans began when he swore revenge for the death of his eldest son Grant; his other two children, Joseph and Rose, would go on to join the Titans to oppose him. A bicolored black-and-orange mask that covers his missing right eye serves as Deathstroke's visual motif.

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.

Timothy Jackson "Tim" Drake is a superhero appearing in American comic books published by DC Comics, commonly in association with the superhero Batman. Created by Marv Wolfman and Pat Broderick, he first appeared in Batman #436 (August 1989) as the third character to assume the role of Batman's crime-fighting partner and sidekick Robin. Following the events of Batman: Battle for the Cowl in 2009, Drake adopted the identity of Red Robin. In 2019, Tim returned to his original Robin persona and briefly used the mononym "Drake".

As a young boy, Tim was in the audience the night Dick Grayson's parents were murdered and later managed to discover the identities of Batman and the original Robin through their exploits. After the death of the second Robin, Jason Todd, and witnessing Batman spiral into darkness, Tim attempted to convince Dick to resume the role of Robin, stating that "Batman needs a Robin". However, Dick refused to return to being Batman's sidekick, and instead, Tim was appointed as the third Robin. Neal Adams redesigned the entire Robin costume specifically for Tim Drake's character, with the sole exception of the redesigned "R" logo by Norm Breyfogle.

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.
