I know of a few(including one I am helping gather) DC cosplay groups for photos and such that are going on!
So who's cosplaying a DC character? And who are you cosplaying?
For me I am debuting my own vision of the Joker, and bringing my main cosplay of my Bane.
If you haven't seen my Bane I debuted at NYCC '12 and was very successful:
