The first rule of superhero fight club? Geek the eff out over superhero fight club.
The CW's latest Arrow/Flash promo features the Arrow (Stephen Amell) bringing the Flash (Grant Gustin) down to the basement of what is formerly known as Queen Consolidated to participate in –what else?—a superhero fight club.
In the no-rules arena, Canary (Katie Cassidy) fights Arsenal (Colton Haynes), Flash has a showdown with Reverse Flash (Tom Cavanaugh), Heat Wave (Dominic Purcell) has a series fanboy moment over Firestorm (Robbie Amell), and it's basically a bunch of superheroes geeking out over each other in the only way they know how: with violence. Super cool, well-choreographed violence, that is.
