Personal DataRichard Grayson of Earth-2. Son of John and Mary Grayson. Ward of Bruce Wayne/Batman of Earth-2. Cousin of Charles "Chuck" Grayson.
Residence: Gotham City of Earth-2; briefly Capetown, South Africa
Robin became the millionaire's constant companion. Wayne saw that Grayson got the best in formal education as well as private tutelage in detective work, criminology, and martial arts. Robin became a skilled mystery-man in his own right, joining Batman in pursuit of dangerous criminals like the Joker (Batman #1) and in becoming a member of the All-Star Squadron, a loosely organized team of mystery-men during World War II (All-Star Squadron #3). Later in the war years, as he approached adulthood, Robin began to work more independently, working his own cases and defeating several professional criminals such as No-Face (Star-Spangled Comics #66), The Clock (Star-Spangled Comics #70) and The Fence (Star-Spangled Comics #76). When the war was over, Robin attended college but remained active as Batman's partner.
Unlike many of the other mystery-men of the 1940s, Robin remained active into the 1950s due to his relationship with Batman and the Gotham City Police Department. During this time, he grew to maturity and entered law school where he obtained his juris doctor degree. He later became a partner in the law firm of Crantson and Grayson, which became Crantson, Grayson, and Wayne when Helena Wayne, daughter of Bruce Wayne, joined the firm. When Batman entered semi-retirement in the 1960s, Robin became one of Gotham City's leading crimefighters and took Batman's place in the roster of the Justice Society of America (Justice League of America #55). During the Carter Administration, Grayson was granted a diplomatic appointment in South Africa, which ended in 1981 (first seen in All-Star Comics #58). After this, he returned to Gotham to resume his partnership in Crantson, Grayson, and Wayne. During the 1980s, Robin's activity decreased, focusing more on his legal career and allowing Batman's daughter, Helena (The Huntress), to take his place. Following Batman's death (Adventure Comics #462), Robin considered taking up the role of his mentor, but he and Helena decided to let Batman's legend end with him. Robin did briefly wear the Batman costume to stop the aging Joker, who escaped from Arkham after Batman's death to determine if the Dark Knight was truly dead (Wonder Woman vol.1 #281-283).
During the Crisis on Infinite Earths, Robin and the Huntress joined
the struggle. In the aftermath, they found that their identities had been
erased from human history (Crisis on Infinite Earths #11). In the
final struggle against the Anti-Monitor's shadow-demons, Robin was slain
trying to protect the injured Huntress (Crisis on Infinite Earths
#12). He and Helena were laid to rest in simple ceremony by the JSA (Last
Days of the Justice Society #1). However, with the death of the multiverse
and stabilization of history, neither humanity nor the JSA remembers the
Golden Age version of Robin, the Boy Wonder.
