Robin is the name of several fictional superheroes appearing in American comic books published by DC Comics. Bob Kane, Bill Finger, and Jerry Robinson originally created the character, to serve as a junior counterpart to the superhero Batman. 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. 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 team of Batman and Robin has commonly been referred to as the Caped Crusaders or Dynamic Duo.
