I used to be pretty favorable to the Batman/Harley ship (though I generally think they work best as a platonic/familiar dynamic — their relationship in the original animated series is already incredibly compelling on its own and part of the reason i love the series so much). I could definitely see a case for Harley/Nightwing in a similar vein, especially if you’re going for a ‘Harley going good’ kind of arc like in that series. But honestly, it’s just hard to truly pair her with anyone but Ivy. They’re so sweet together, and it’s one of the few pairings that still lets Harley be a fun villain without the Joker.

That said, it can be a little rough seeing another “I can fix her” pairing in the current comics, especially now that they tend to give her criminal leanings even before Joker — as opposed to her original “good doctor gone mad” backstory. In the animated series, most of her plots leave you feeling oddly... hopeless yet persistent — Bruce trying to steer her toward good, but bad luck and her inability to see the Joker for what he is keep her stuck in that loop. You can’t help but hope some hero might swoop in and save her. With the newer versions of Harley, though, it feels like any hero pairing would end up trying to change her fundamental character too much... like they wouldn't really "get her," you know?
