YMMV / Supergirl (2015) S2E4 "Survivors"

• Complete Monster: Veronica "Roulette" Sinclair is a ringmaster who organized an underground fight club in National City, commanding aliens to fight to the death for money to entertain rich people, including herself. In her first appearance, when J'onn and M'gann refuse to fight, Roulette releases Draaga to try to kill them both, but gets arrested. Upon being freed due to her connections, Roulette, with the help of an alien doctor, plans to sell humans in a slave market on Maaldoria in exchange for a large amount of diamonds. Utterly apathetic to aliens and human beings alike, Roulette is a Rich Bitch who has no qualms against making quick money at the expense of others.
