Except Sirens is written by Paul Dini. Setting aside his work with the character in the animated series, his most recent work with her in Detective Comics...even worse than this.
Ivy is attacked by a giant plant in her cell. She escapes it. It grabs her. She disappears, and reappears, sans clothing, outside a police station, begging for help and bleary-eyed. Batman shows no sympathy (or even suspicion of attempted sexual assault), merely knocking her out and taking her to the cave. We find out that the giant plant is - in a move almost as stupid as something written by Loeb - a ripoff of the plant from "Little Shop of Horrors" that absorbs the souls of those it has eaten.
The Plant breaks into the cave, it then graphically rapes Ivy, on-panel, in a large whole-page spread - though we don't see penetration, she's pretty much bound, gagged and whimpering. Batman out-mans it and it disappears forever, followed by Ivy - still traumatised - developing a violent phobia of her own powers, rendering her powerless and useless.
I await with glee the day that Dini retires or is fired from DC, and can no longer get his dirty paws on the female characters of the Bat-verse. It's seriously like he just wants to carry on the DCAU except with as many horrible sexual fetishes as possible shoved in.
