Grudge Match
Roulette (Virginia Madsen) and Lex Luthor (Clancy Brown) decide to boost the ratings and fortunes of Metabrawl, their underground boxing ring, by using superpowered female fighters instead of human combatants. To fill the ring each night, Roulette and Luthor tap into the Justice League communicator that the heroes all wear in their ear, and use it to place the female members of the League under mind control.

When Huntress (Amy Acker), who is not in the League, tracks Black Canary (Morena Baccarin) to a match, she uncovers the plot and manages to free Canary. Roulette forces the two women to fight two other mind-controlled heroines: Vixen (Gina Torres) and Hawkgirl (Maria Canals), but it ends with Vixen and Hawkgirl being freed as well. Roulette then calls on Wonder Woman (Susan Eisenberg) to defeat them. Wonder Woman is more powerful than the other four fighters combined, so Huntress and Canary engineer an escape from the ring and shut down the mind control signal.
