Beat-Down

From publisher blurb: And In THIS Corner ... In a different location each time, there exists in the dark streets of New York City a secret club where the influential and wealthy gather to have a night of drinking, carousing, and revelry, while watching super-human gladiators fight. This secret club is called “The Beat-Down.” Down-on-their-luck heroes and villains sign up with the Beat-Down to make a few bucks until something better comes along. Super Powered Legends. Because sometimes you a need characters everyone knows, even if they're meeting them for the first time.
