DC had two very minor villains, Coldsnap and Heatstroke, who were part of the Masters of Disaster (villains for Batman and the Outsiders) back in the 80's. They were lovers who, because of their powers, could never touch each other. They took villain jobs to make money to fund their efforts to get rid of their powers. They had one scene in particular in one story, where The Outsiders and the Masters were on the villainous mastermind's island hunting each other, and Coldsnap and Heatstroke found a device that Coldsnap felt he could jerry-rig into something that could transfer part of their powers to each other. Before he had a chance, Batman pops in and blows up said device, knocking the two out in the process. Bats had no way of knowing what he was doing, he was just taking the bad guys out, but he still comes off looking like a bit of a douche.

Harley and Gobby. OK, it's just a fanfic, but the relationship is simultaneously hilarious, sweet, and insane (in every sense of the word).
Ukrainian Red CrossI think retcons may have made them less villainous, and there was always some level of moral ambiguity, but Mystique and Destiny were cool.
I also liked Absorbing Man and Titania. Though they're as evil as any comic couple who aren't implied to be highly dysfunctional that I can think of.
Am I a good man or a bad man?

Because Even Evil Has Loved Ones. Who are your favorites from comics?
I'm sure most people's choice will be Joker and Harley (or even ivy and Harley which I can get behind) but I don't like those two that much.
My choices would be:
1, Absorbing Man and Titania. Neither one is all that villainous and they've had several very touching moments. Despite them being antagonists I feel sorry for them more than anything. (I'm also not sure if they're even together anymore)
2. Crossbones & Sin
◊ Not much you can say about these two except I love to watch them be evil together. Plus the issue where Crossbones tortures her back to normal was sweet in a depraved sort of way.
