Rocksteady and WB Games Montreal’s Arkhamverse tetralogy featuring Batman introduced a great number of antagonists. Some antagonists were backburned for others, while some would go on to become a main villain in a later entry. The Joker is extremely prevalent in the Arkhamverse, for example, and would often overshadow other interesting villain interpretations, such as Batman: Arkham Origins’ Bane. Now that Suicide Squad: Kill the Justice League is on the way, it seems that Harley Quinn is just as paramount to the Arkhamverse as Batman is.
