The original Royal Flush Gang was Professor Amos Fortune's childhood gang. With Fortune himself as Ace, they fought the Justice League on two occasions, using Fortune's luck-altering "stellaration" technology to realize the fortune-telling significance of playing cards. After Fortune abandoned the Gang, they attempted to steal paintings containing clues to a hidden treasure but were thwarted by the Joker's manipulations (Joker #6). Most of them then abandoned their criminal careers, although Jack briefly joined the Secret Society of Super Villains as "Hi-Jack". Fortune's gang wore costumes based on the suit of clubs.
In the pages of JLA Classified, it was revealed the original Royal Flush Gang (sans Amos Fortune) reunited to fight the "Detroit Era" Justice League and their successors in the second gang. In this battle, the original King, Queen, and Ten were all killed.
