Speaking of Catwoman, I just remembered her solo mini-series from about 1990 or so.
Look at the cover of the first issue.

"In the RUINS OF INNOCENCE" in giant bold letters over a hooker's obviously recently-raped body.
Man. Comics were different in the 90s. This would probably get banned by twitter SJWs before it could ever get published, cause how dare they ever imply a woman can be a victim?? Still, it's pretty tacky to put something that graphic on the front cover to gain attention. It was only a year or two after Killing Joke though, so I guess that was edgy thing DC was doing at the time.
I had this miniseries and I don't remember if there was any explicit sexual assault, but she definitely got beat up. And was a hooker. Then Wildcat taught her how to fight in the gym, and she became the kinda-villain she's been ever since. But man, she had the worst butch man-cut hairdo in this and Year One. Gross.
And I think the follow up story, which was in DC Showcase, shows her best friend in the world, an adorable UNDERAGE HOOKER get blown up by street gangs or something. Can't really remember. It's been a while, but I remember thinking this was some graphic stuff. And it stayed that way for years til they quietly retconned her having sex with men for money out of her origin.
The 90s were a different time, man.
