The female characters had composite storylines too, but back in the day the producers started shortening and combining the stories to fit them in cinematics and cartoons. The unexplored female characters from the Batman universe are a gold mine for any female movie producer interested in exploring the psychology behind the Batman/Bruce Wayne character. Harley Quinn is a character with her own story, she addresses issues such as inequality, injustice and compassion - she's not entirely a villain, she helps the orphans and when she finds out Batman is an orphan, she has a change of heart. The entire Batman universe is about kids who became orphans - some became heroes and some became villains.
