15 Weirdest Romantic Superhero Relationships

Harley Quinn is the Clown Prince of Crime's main squeeze and number one hench girl. Poison Ivy is a bioterrorist fighting to save Earth at the cost of killing off humankind. Somehow the two of them wound up together. Which, okay, is a bit odd since the two did not seem to have a lot to do with each other until they suddenly ended up living together.

But once together, everyone saw how well they worked, regardless of how odd it was that two of Batman's enemies had just started dating. And they've kept dating. Their relationship shows no sign of slowly down.

Honestly, the weirdest thing about their relationship is how well the two work together. There's a common belief that couples can't be interesting, especially in comics. It's why Superman and his wife are going through rough times, why Spider-Man can't be married, and why Batman was just stood up at the altar. But Poison Ivy and Harley Quinn are just interesting enough characters that they can rest easy in their relationship and still have so much interesting to do.

Heck, the biggest recent DC comics crossover, Heroes in Crisis, is largely based around their relationship with each other, and how much they care about each other.
