Under normal circumstances, Joker had a spot of trouble in what he wanted to do with Batgirl. Sure, he could hurt and torment her, but to really get her where he wanted her took a sweet spot he couldn't quite reach.
The Master PC would change everything. A few words and a line later...
"Oh Batbint, get in here!"
In seconds, the defeated caped crimefighter came shuffling into the room. Ripped spandex, messy red hair, covered in dirt, it was clear Batgirl had fought a battle with the Joker and lost. A battle he didn't remember, but that mattered little. A long tear down the front of the chest exposed Batgirl's breasts, decorated as they were with a giant bloody bat symbol, the word "HA!" all about, and Joker faces dangling off her nipple piercings. A bullseye over her womb added some mirth for the villain clown.
What Batgirl wore best, though, was a defiant glare. Like even though she obeyed his commands, she wanted to rob him of the satisfaction of thinking he broke her. That was the sweet spot - following his commands, but loathing them.
"What do you want now?" Batgirl said.
Despite how bad he wanted this, Joker hadn't thought of what he might do with Batgirl if it ever happened. It took some thought, but finally he decided.
