|Royal Flush Gang|
The Royal Flush Gang were a family of bank robbers. In the comics, the Royal Flush Gang is depicted as a superpowered group of individuals, which were very different from the TV show's interpretation of them.
- King, (leader)
- The Royal Flush Gang depicted here are similar to the Joker's clown henchmen in The Dark Knight. They wear customised masks. Their first appearance was robbing a bank, and they manage to give the police the slip by putting masks on hostages.
