Richard "Dick" Grayson is a superhero appearing in American comic books published by DC Comics, commonly in association with Batman, Teen Titans and Justice League. Created by writer Bill Finger and artist Bob Kane, he first appeared in Detective Comics #38 in April 1940 as the original and most popular incarnation of Robin, Batman's crime-fighting partner. He is also the oldest child of Bruce Wayne, Batman's alter ego, being the first child to be adopted by Batman. In Tales of the Teen Titans #44, the character, after becoming a young adult, retires his role as Robin and assumes the superhero persona of Nightwing. Grayson has donned the cape and cowl to replace Bruce Wayne as Batman. His most notable spell as Batman followed Bruce Wayne's supposed death in Final Crisis, and sees Grayson adopt Damian Wayne, Bruce's biological son and his adoptive younger brother, as his Robin.

The Teen Titans are a superhero team appearing in American comic books published by DC Comics, frequently in eponymous monthly series. As the group's name indicates, the members are teenage superheroes, many of whom have acted as sidekicks to DC's premier superheroes in the Justice League. The original team later becomes known as the Titans when the members age out of their teenage years, while the Teen Titans name is continued by subsequent generations of young heroes. First appearing in 1964 in The Brave and the Bold #54, the team was formed by Kid Flash, Robin, and Aqualad (Garth) before adopting the name Teen Titans in issue 60 with the addition of Wonder Girl to their ranks.
