Robin of Earth-Two.

About Robin of Earth-Two

Robin of Earth-Two is an alternate version of the superhero Robin, who appears in American comic books published by DC Comics. The character was introduced after DC Comics created Earth-Two, a parallel world that was retroactively established as the home of characters which had been published in the Golden Age of comic books. This allowed creators to publish comic books taking place in current continuity while being able to disregard Golden Age stories featuring Robin, solving an incongruity, as Robin had been published as a single ongoing incarnation since inception. Unlike his main counterpart, Robin is the only alter ego of Dick Grayson, who uses the title into adulthood, rather than taking on later codenames such as Nightwing or Batman. In addition, the name "Robin" is not taken on by later characters.
