15 Weirdest Romantic Superhero Relationships
2. Batman & Batgirl
Batman is the father of the Bat-family. His is the one who lost his whole family only to found another one. The daughter of his best friend and closest ally, Jim Gordon, joined that family as Batgirl. Most versions of the Batman/Batgirl relationship feature her as an annoying niece who is too smart to ignore, or - at weirdest - the closest thing that Batman has to a sister. But then there was the animated adaptation of the Killing Joke, and there was Batman Beyond 2.0
This movie, about Barbara Gordon being paralysed by the Joker, features an extended sequence telling the tale of Batman and Batgirl's romantic relationship. Which is weird and creepy for so many reasons -- the age difference, his oddly paternal role over her, the fact that he is best friends with her dad -- it also made it canon that Batgirl and Batman don't care about Dick Grayson at all, because when the two of them get together, she's dating Robin. And continues dating him. For awhile.
But then Batman Beyond 2.0, a comic series dealing with what happens after the comics end, shows that during Batman and Batgirl's relationship, Batgirl got pregnant.
It's the weirdest, most sexually odd Batman story ever, which is saying something. Don't worry about the Batbaby though, Barbara Gordon miscarried it while Bruce told Dick what he had done because Batman is truly a psychosexual drama.
