Seems I hardly know squat about New 52 if I didn't know Harleen was in the family. In what way was she?

How do you mean? Like, how she acts now as a member of the Batman Family?

Yeah, like how does she count as a member? Extended?

Oh. Well, in some of the issues of the Batman run being #108, 109, and a couple others onward, she worked with the likes of Batman and Ghost-Maker. All three were on a mission, before Batman could report to them, Harley and Ghost-Maker were browsing around his cave, they drank champagne together, and were in a sword training fight with each, and yeah. Also, Harley was trying to completely reform herself into a full-fledged hero in “The Joker War” run in 2021 written by James Tynion IV. So, she joined Batman’s family to try to learn to be good again and better herself and fix all the crimes she’s done in the past, and she actually managed to do well. She helped the Birds of Prey in the 2023 run save Black Canary’s sister, Sin, and she’s done more.

Batgirl.

Duke... The others are either too unpredictable or would read too much into hanging out.

Im surprised Harley isnt on top yet.

Robin

I'm going with my favourite Batman.

Probably Stephanie, to be honest.
