Harley Quinn
The series began being published in November 2013, starting with "Harley Quinn" #0, which brought together seventeen comic book artists, including Harley Quinn co-creator Bruce Timm, to illustrate a fourth wall-breaking story about Harley thinking of the artists that could illustrate her in her own comic book series. The rest of the series details Harley Quinn's adventures in Coney Island with her supporting cast. In "Harley Quinn" #25, Palmiotti and Conner reunited Harley Quinn with the Joker after two years of not being together in comics; the story depicts Harley Quinn returning to Gotham City to confront the Joker and end their relationship.
