8 Crazy Video Game Fan Theories That Actually Improve Games

6. Batman Kills Harley Quinn's Baby

But... Batman's not a killer, is he? IS HE?!

According to one great Reddit theory, Batman makes Harley Quinn miscarry in Arkham City. There are hints throughout the game that Harley is pregnant with Joker's offspring, from the pregnancy test to the lullaby she sings creepily in the credits. Admittedly, the DLC says she wasn't and that the tests she used could offer false positives, but that doesn't mean anything. Evidence is no theory killer after all.

If you think back to her first appearance in the game, she tries to attack Batman only to be thrown into a beam, connecting in her midriff and promptly sitting in what looks like agony. At first, you'd be forgiven for thinking she's exaggerating, since it can't possibly have hurt that much, but then with the other evidence in place... Batman becomes a baby-killing murderer.

Boom, instantly more complexity to the character.
