Some of the enemies of the comic book superhero the Flash, led by Captain Cold, constitute a loose criminal association who refer to themselves as the Rogues, disdaining the use of the term "supervillain" or "super-criminal".The Rogues, compared to similar collections of supervillains in the DC Universe, are an unusually social group, maintaining a code of conduct as well as high standards for acceptance. No Rogue may inherit another Rogue's identity (a "legacy" villain, for example) while the original still lives. Also, simply acquiring a former Rogue's costume, gear, or abilities is not sufficient to become a Rogue, even if the previous member is already dead.
