Do you have what it takes to join the Gang of Harleys?

Harley Quinn collaborators Amanda Conner and Jimmy Palmiotti will host the first "Great Harley Quinn Cosplayer Showdown" Friday at the DC Entertainment booth at Comic-Con International.

The official rules can be found on the DC website, but here's the gist of the contest: Come to the DC booth (#1915) Friday at 3:30 p.m. dressed as Harley Quinn (the costume must be 50 percent made or "significantly modified from original garments"). A panel of judges will determine first the finalists and then the winners based on creativity, attitude, overall adherence to the character, and enthusiasm.

The grand-prize winner will receive signed copies of the first two hardcover collections of Harley Quinn; the runner-up will get a signed copy of the first volume.
