Rogues (comics)
Some of the enemies of the comic book megahero the Flash, led by Captain Cold, constitute a loose criminal association who refer to themselves as the Rogues, disdaining the use of the term "super villain" 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. They don't kill anybody unless it's necessary. Additionally, the Rogues refrain from drug usage.
Although they tend to lack the wider name recognition of the villains who oppose Batman and Superman, the enemies of the Flash form a distinctive rogues gallery through their unique blend of colorful costumes, diverse powers, and unusual abilities. They lack any one defining element or theme between them, and have no significant ambitions in their criminal enterprises beyond relatively petty robberies.
