|Bio: The ringleader of the illegal meta-human battles, Roulette
commanded a large sum of the rich citizens in the city’s money;
wagering on her fights between meta-humans, she made millions
with her prized fighter, the human Wildcat. When his friends
attempted to break him out of the battles and his fighting
obsession, Black Canary and Green Arrow brought it al down on
top Roulette—literally. Using her canary scream, Black Canary
toppled the stadium into rubble.
After not being able to recoup her losses from her Meta Brawls, she
turned to Luthor for help. Since Luthor received some of the profits
from the matches, he gave Roulette the ability to control the female
members of the Justice League via their comm links. She had the biggest
names in the Justice League show up to fight, but her plan was foiled
when Huntress tracked Black Canary and discovered her ploy.
