Flying Trapeze

The Flying Graysons are fictional characters appearing in American comic books published by DC Comics. They were a family of trapeze artists in Haly's Circus, of which Dick Grayson was a member. After his parents are killed by mob boss Tony Zucco in retaliation for the circus' boss not paying him protection money, the orphaned Dick is adopted by Bruce Wayne aka Batman and becomes his sidekick, Robin. The Flying Graysons have been featured in several media adaptions outside of comics, commonly as part of Robin's origin story.
