Robin (character) episodes that this Robin is Dick Grayson. In the season two episode "Fractured", a version of Bat-Mite is introduced who claims to be Robin's "DNA buddy" (genetic twin). Bat-Mite gives his name as Nosyarg Kcid ("Dick Grayson" spelled backwards). In another episode, Raven reads Robin's mind and sees a man and a woman falling from a trapeze (an event known only to have happened to Grayson and not to any other Robin). In another episode, Starfire travels to the future and discovers that Robin has taken the identity of Nightwing. Menville reprises his role as Robin in "Teen Titans Go!".
Alternative versions of Robin and his status as a crime-fighter with the Justice Society certainly reflected what had gone before. After the events of Flashpoint, Helena Wayne, daughter of Earth-2's Batman and Catwoman served as Robin and became the only partner that Batman had ever had. In this continuity, Bruce Wayne had never adopted Dick Grayson as his ward, so he never became Robin on Earth-2. However, he does appear later, married to Earth-2's Barbara Gordon, who never became Batgirl on Earth-2. The second Talon is shown in "Teen Titans" #38 (2006), the former sidekick of Owlman, created by Geoff Johns and Tony S.
