Harley Quinn and Her Gang of Harleys (2016-) #6

This is it! The moment you've been waiting six long issues for! The identity of Harley Sinn is revealed, and Harley's gang has found their great leader. But trouble is only beginning for Har-oh who are we kidding? This is the issue where Harley and her Gang kick butt on her captors (and she gets quite a few shots with her mallet as well), as Harley Quinn teaches her gang the most important lesson of all: losing stinks, so win-and never leave Brooklyn if you can help it.
