>>85165601 Originally she was simply designed to be a slightly sexualized pun-themed hench-goon in a children's cartoon, when they expanded her backstory to make her a brainwashing victim in "mad love" with "Mr.J." but then somebody decided that the Joker's love slave shouldn't be that wholesome...
So they reimagined her brainwashing as less Joker exploiting her undiagnosed insanity and more as Joker pimping her out.
This might make more real-world sense, but they're fucking comics, there was no need to sexualize her victimization. The idjits at DC should have known that.
