When Gorilla Grodd sought to steal the Flash's speed and finally vanquist his old foe, he teleported six Central City felons... Captain Cold, Pied Piper, Top, Captain Boomerang, Heat Wave and Mirror Master.... to distract the speedster. However, the Flash defeated this Rogues Gallery, just as he had when he ventured from Earth-One to Earth-Two to aid his counterpart versus that Flash's foes Fiddler, Shade and Thinker. In both Central and Keystone City, various combinations of Flash foes would teamup from time to time throughout the years to plague both Scarlet Speedsters. However, their petty schemes never matched their meticulous crimson enemies.
Central City had it's Rogues Gallery, Keystone City had it's Lairs Club. Both were less than honorable societies. The former were filled with Felons who faced the Flash. The latter were lads who laughed at their Flash. And his tales, which seemed as outlandish as those of his counterpart a universe away.
While the Rogues were colorful costumed criminals, the Liars were more dignified in their posh suits. Additionally, they included as their member the alter ego of the Flash, Jay Garrick, who spun tales of his battles with foes like Tag "Eel" Madden and alongside the Three Dimwits. Decades later, it was Barry "Flash" Allen who had real life tales versus his own set of adversaries.
