Roulette

Roulette (Veronica Sinclair) is a supervillainess in the DC Comics universe. Publication history Roulette first appeared in JSA Secret Files #2 (September 2001) and was created by Geoff Johns and Derec Aucoin. Fictional character biography Roulette's grandfather was a Golden Age villain of the same name, who ran a conventional casino and fought Terry Sloane. The current Roulette believes Terry Sloane to be her grandfather, but it is indicated that her grandfather was actually Terry’s brother Ned. Both Roulette and Ned have been added into Mr. Terrific's history, and do not appear in the original stories. Having encountered the second Mister Terrific during one of her schemes, she has come to view him as an unworthy successor to Sloane. Her casino ("The House") is a superhuman gladiatorial arena, capturing heroes with teleporter technology similar to Holt's T-Spheres, and pitting them against each other, while various supervillains bet on the outcome.
