Robin is the name of several fictional characters appearing in comic books published by DC Comics, originally created by Bob Kane, Bill Finger and Jerry Robinson, as a junior counterpart to DC Comics superhero Batman. The team of Batman and Robin is commonly referred to as the Dynamic Duo or the Caped Crusaders. The character's first incarnation Dick Grayson debuted in Detective Comics #38 (April 1940). Conceived as a vehicle to attract young readership, Robin garnered overwhelmingly positive critical reception, doubling the sales of the Batman related comic books. The early adventures of Robin included Star Spangled Comics #65–130 (1947–1952), which was the character's first solo feature. Robin 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 debuted in Batman #357 (1983). This Robin made regular appearances in Batman related comic books until 1988, when the character was murdered by the Joker in the storyline "A Death in the Family" (1989). Jason would later find himself alive after a reality changing incident, eventually becoming the Red Hood. The premiere Robin limited series was published in 1991 which featured the character's third incarnation Tim Drake training to earn the role of Batman's junior partner. Following two successful sequels, the monthly Robin ongoing series began in 1993 and ended in early 2009, which also helped his transition from sidekick to a superhero in his own right. The fourth Robin incarnation was established DC Comics character Stephanie Brown and thus the first in-continuity female version of the character. But shortly after her acquisition of the Robin mantle, she was stripped of the identity by Batman and was apparently killed by the supervillain Black Mask in the crossover Batman: War Games (2004). It has since been revealed that her death was a ruse and she eventually returned to resume her previous identity before becoming the sixth Batgirl. In the final issue of "Battle for the Cowl", Damian Wayne (Bruce Wayne's son) becomes the new Robin. Following the 2011 continuity reboot "The New 52", Tim Drake is revised as having assumed the title Red Robin out of deference to the deceased Jason Todd; Jason Todd, as he exists today; operates as the Red Hood and has been slowly repairing his relationship with Batman; Dick Grayson reclaims his role as Nightwing; and Stephanie Brown is unheard of, prior to her being reintroduced as Spoiler in the pages of Batman Eternal (2014). After Damian is killed in a 2013 story, the position of Robin becomes vacant.
Robins have also been featured throughout stories set in parallel worlds, owing to DC's longstanding "Multiverse" conceit. For example, in the original Earth-Two, Dick Grayson never adopted the name Nightwing, and continues operating as Robin into adulthood. In The New 52's new "Earth-2" continuity, Robin is Helena Wayne, daughter of Batman and Catwoman, who was stranded in the Earth of the main continuity following her father's death at the hands of an alien invasion. Operating alongside Power Girl on Prime Earth, she takes the name Huntress
