This might be a long shot and no one knows what I’m asking about but there was a batman comic I read a while ago on this site and I can’t remember what it was.
It was about Batman he got captured by a old(er?) lady , with I think white hair, and then she made him fight and then she fell in love with him or something because she liked the way he fought and his muscles? And then I think batman beat her in the end.
Sorry if it’s super vague but I tried googling it and scrolling through the covers of Batmans and no luck. Just thought someone might know.
