Flying Graysons

History
The Flying Graysons were an acrobat group in Haley's circus. It consisted of John and Mary Grayson, and their young son Dick.

When Dick was twelve, Haly’s Circus came to Gotham. A new crime lord named Tony Zuccoattended a special performance of the Flying Graysons during an “Elect Dent” fundraiser event. Zucco tried to shake down Jack Haly, the owner of Haly’s Circus, wanting him to pay Zuccos protection money for the duration of their stay in Gotham. Dick overheard Mr. Haly’s refusal and later that night, Dick watched in horror as the high wire snapped, sending Dick’s parents to their deaths in front of Gotham’s rich and powerful.
