10 Horrifying Comic Implications
8. There May Have Been More Than One Harley Quinn
Death of the Family is full of mind games, as the Joker - fresh off the block and psyched up having just cut off his own face - tortures not only the assorted Batclan, but also his former sidekick and beaut, Harley Quinn.
Only, it's revealed she may have not been the only one. In an especially nasty twist, the Clown Prince of Crime reveals the bodies of several skeletons, all wearing costumes that look like different revamps of Harley's own. To confirm what this makes us suspect, Joker tells her that she wasn't the first Harley, and that she won't be the last - raising the very real possibility that he has killed a series of other women he have the moniker to.
While this seems like a hopefully false lead - as Harley's villain name is based on her real name, and the Joker spends a lot of Death of the Family just messing with people for the fun of it - knowing just how off the rails he is, we can't totally write it off.
