Richard John "Dick" Grayson was a vigilante known as Robin and the former protégé of Batman. However, one day in 2002, both of his parents were killed mid-act in fall before a packed crowd,[5] and the devastated Dick would be promptly adopted by Bruce Wayne. Grayson was later trained by Wayne to become the vigilante "Robin" and fight crime by his side as Batman,[6] forming "the Dynamic Duo."[7] However, in 2011, while on a mission on behalf of his mentor, he was kidnapped, tortured and murdered by the Joker and Harley Quinn, who set him ablaze and defaced his suit, now kept in the Batcave. Robin was avenged by Batman when the latter broke the Joker's teeth, permanently damaging his smile, and later captured Harley Quinn for his murder.
