Roulette was a conniving entrepreneur who ran an illegal, no-halt, cage fighting league—the Meta-Brawl.
Roulette ran a successful, underground fighting ring, featuring super-powered villains to entertain Gotham's elite. Among her criminal roster was also the crime fighter Wildcat, whom she recruited by playing on his "mid-life crisis". He was her biggest contender and her business thrived mostly thanks to him. However, all of this changed when Black Canary and Green Arrow broke into Meta-Brawl to extricate Wildcat, thus depriving Roulette of her main source of income.
Consequently, Roulette turned to Grodd, who supplied her with contenders from the Legion of Doom in exchange for a cut of the profits. However, when Lex Luthor overthrew Grodd and took over the Legion, Roulette's revenues decreased significantly. So, she sought Luthor for commiseration, and following an argument with a jealously possessive Tala, they came up with a new concept for the Meta-Brawl: Glamor Slam, a no-halt cage fighting tourney in which the main contestants would be female Justice Leaguers.
Roulette set up a new arena in Blüdhaven and, thanks to Grodd's mind controlling technology, recruited the League's most prominent heroines. Her most valuable attraction was Black Canary, who managed to retain the champion title for some time. However, when Canary broke free of her control thanks to Huntress's meddling, Roulette pitted both of them against the might of the unwitting Vixen and Shayera. Then, when the they also snapped out of their mind manipulation, Roulette unleashed her secret weapon: a mind-controlled Wonder Woman. While the Amazon princess spread havoc all over the arena, Roulette was confronted by Huntress in a hand-to-hand combat. She revealed herself to be a cunning martial artist, but despite her talents, Roulette was eventually overpowered by Huntress. The Glamor Slam was shut down and Roulette was finally arrested.
Veronica Sinclair, a.k.a. Roulette, first appeared in JSA Secret Files #2 (September 2001). She ran "The House", an underground Casino for super-villains where mentally-controlled superheroes were compelled to fight each other to death. Roulette was responsible for the death of many superheroes, including most of the members of Hybrid, and Firebrand III. She also abducted seven members of the Justice Society, but that maneuver caused her arena's destruction. Roulette had no powers of her own, but she was endowed with a keen intellect, and surrounded herself with all sorts of security gimmicks, such as death traps and robot security dogs. Roulette is the granddaughter of her namesake Golden Age villainess, who clashed with Mr. Terrific (I) and had an affair with his brother, Ned.
