Richard Grayson

Richard "Dick" Grayson was a member of a circus group until his family was murdered. Grayson was then adopted by Bruce Wayne, alias Batman, who trained him to fight alongside him during his war on crime. Grayson was the first to assume the Robin identity.

Return as "The Joker"
Sometime after abandoning his role as Robin, Grayson began working for a group of individuals that allowed him to undergo radical gene therapy that provided him with superhuman abilities. With these newfound abilities, Grayson became the second Joker, as he murdered several people, specifically targeting costumed heroes. When Grayson attempted to murder Catgirl, Batman intervened. After an emotionally charged conflict, Grayson met his demise when Batman destroyed the Batcave with volcanic magma.
