Harley Quinn
The Harley Quinn LEGO Minifig may be my favorite Batman LEGO minifigure. She is very well designed by LEGO and can be used for other LEGO theme sets besides Batman, for instance a Jester in a royal court for the Castle LEGO Sets. The Harley Quinn LEGO minifig also has awesome weapons, she carries a gun and an oversized hammer! Harley Quinn is a part of the Batcycle: Harley Quinn's Hammer Truck Batman LEGO Set.
