I think it comes from the same deep french vein as stuff like this?
It would be easy to just say that french feminists married sexuality and power dynamics in a way that was taboo in the U.S. but I don't think that's accurate. There is this long running vein of french comics and pulp with strong female characters, but they're always sexualized and mostly drawn and written by men.
I'm no Francophile or french scholar, but the powerful bimbo is a long running tradition in French pop culture and I don't know why
