- "That's the last time I trust a woman with a dragon tattoo." – Oliver Queen about Victoria, Roulette
Roulette is an attractive young Asian woman who wears a red Chinese dress and heels as well as chopsticks in her hair. She also has a dragon tattoo which starts on her left shoulder plate and ends down her leg.
- "But I've seen you before. Your type. The player who can't find a game to satisfy him." – Victoria Sinclair, to Oliver Queen, Roulette
Victoria found Oliver Queen in a casino that she ran called Roulette. Oliver flirted with her, then Victoria offered to play a little game; Oliver agreed. She gave him a tablet which caused Oliver to fall unconscious in the street; then she kidnapped him.
Trying to seek a solution to the dangerous game he was playing, Oliver returned to the casino and found Victoria there. She made him believe that she was only a pawn and that his life would be in danger if she did not follow the orders of her boss. Victoria faked her death, leaving Oliver to be accused of murder; she used her employees to make Oliver reveal the password of his bank account and then steal all the money he had.
Later, Victoria fought with Lois Lane in the street and kidnapped her, then made her pose as her with the hope that Oliver would kill her by mistake.
When this did not happen, Victoria tried to escape from the casino through the kitchen, but an explosion occurred and she became trapped. When Oliver went to rescue her, Victoria asked him why he returned for her, to which Oliver replied that he couldn't let her die. She then came out from under the rubble in which she was caught, revealing that it was a fake fire and that everything was part of a plan to make Oliver rethink his life.
Roulette was seen as a member of Toyman's Marionette Ventures. At their group meeting about dealing with Clark Kent's team of heroes, she was given the task of taking out the League's token information supplier: Watchtower.
In the Comics
Roulette is a female DC Comics character who runs a metahuman fighting place called The House. Roulette's grandmother was a Golden Age villain of the same name, who ran a conventional casino and fought Mister Terrific, as well as having a relationship with his brother, Ned. The current Roulette believes Terry Sloane to be her grandfather, rather than great-uncle, and sees the current Mister Terrific as an unworthy successor. 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. In her debut, she captured most of the current Justice Society and forced them to fight each other; Mr. Terrific and Dr. Mid-Nite were forced to play a chess game where the loser would be electrocuted, Sand and Hawkman had to reach Hawkgirl while infected with a fast-acting lethal virus (of which Kendra had enough of the cure for one) while Black Adam clashed with Atom Smasher.
Roulette has no apparent superhuman abilities, but is a genius when calculating odds and gambling winnings. Roulette has robot security dogs, automated security devices, a series of death traps, and at least one metahuman on staff who can negate super-powers.
In Justice League America vol. 2 #35, Roulette appears working with Amos Fortune who has plans to take down the Justice League.
- In the comics, Roulette's alter ego is Veronica Sinclair. But it can be assumed that the writers got the name "Victoria Sinclair" from the DC Comics Encyclopedia where her name was given as "Victoria" rather than Veronica.
- The premise of "The House", the fighting place that Roulette runs in the comics, is similar to the fighting club managed by Richtor Maddox in Season Six's Combat.
