The group has a varying line-up, sometimes consisting of five-to-six members and sometimes having a staggeringly huge membership. Originally the Vicious Circle was led by the Overlord, an armored mastermind who ruled all of Chicago's underworld. Later, it would be ruled by the technology controlling Cyberface. Once the Savage Dragon started policing the streets of Chicago, the Vicious Circle began to falter and its members started winding up in prison, the hospital or just plain dead. The Vicious Circle remains a consistent thorn in the Savage Dragon's side, and frequently faces off with the SuperPatriot and others, including Raphael of the Teenage Mutant Ninja Turtles, who in issues 10 and 11 of the series run with Image took on the entire Vicious Circle himself in a bar fight.
