[1] 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.
[2] 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.
Speedster villains, such as Reverse Flash or Zoom, are typically not welcome within the ranks of the Rogues due to their obsessive, untrustworthy and psychotic behavior.
Confirmed Rogues include the Golden Glider (Lisa Snart) as the current leader, the Weather Wizard (Marco Mardon), the Trickster (Axel Walker), Heat Wave (Mick Rory), and the Mirror Master (Sam Scudder).
A year prior, Captain Cold, Heat Wave, the Mirror Master (Sam Scudder again), and the Weather Wizard underwent a procedure at an unknown facility that would merge them with their weapons, giving them superpowers.
However, they are forced to team up with the Flash, Cold, and the Pied Piper when Gorilla Grodd invaded Central City.
In chronological order (with issue and date of first appearance): In the Modern Age, the graphic novel The Flash: Iron Heights introduced new characters, many of whom would later become a new band of Rogues under the leadership of the crime lord Blacksmith.
This version of the group are police officers and members of the "Reverse-Flash Task Force" from the 25th century, led by Commander Cold and consisting of Heatstroke, Mirror Monarch, Weather Warlock, Trixster, and the Top.
The Rogues appear in the Injustice: Gods Among Us prequel comic, led by Mirror Master and consisting of Golden Glider, Heat Wave, and Weather Wizard.
