15 Weirdest Romantic Superhero Relationships

15. Batman & Joker

Batman is a hard face and a scowl. He makes you swear to him and he wears armor with nipples. Is it any wonder that the Joker is in love?

This isn't some slash fiction either. It has been said, many times, in and out of comics, that the Joker is head over heels in love with Batman. He's been sexually harassing him since the eighties, with him fully developing - or attempting to develop - a full-on relationship with him in the 2010s.

He asks Batman to go away with him because he knows he can make him better, and when he turns him down, the Joker throws himself off a cliff. (He gets better. Then the two die together. But they get better.)

Even the Lego movies know it's true. Looking at the Lego Batman Movie, you can see that the entire plot of that film is the Joker just trying to get Bruce Wayne to admit that he cares about people, admit that he cares about him... that Batman cares about the Joker.

It's an oddly heart-warming scene when the two make a pillar of humans to confess how they care about each other while also holding the world together. But, ah, that's love isn't it?
