More Than One Joker?!?

Yes, you read that right, DC just dropped a HUGE bombshell in Justice League #50 and DC Universe Rebirth #1.  Okay, so it might not be AS huge of a bombshell as Cap being a Hydra agent (I call dibs Arthur), but it's still a pretty massive event.  At the end of JL #42, Batman was able to sit down in the Mobius Chair, and gain access to its vast database of knowledge.  After sitting on his new chair (read throne), Batman asked a question we comic fans have been asking for years.  What's the Joker's real identity?  Well, the answer is complicated.  It turns out that there are three Joker's.  There's the original Joker that first appeared in Jerry Robinson's Batman #1, the much more dark and twisted version from Brian Bolland's The Killing Joke, and Scott Snyder's New 52 Joker.  This strange development leaves more questions than it answers, such as How on EARTH are there there Joker's?  How has Batman never realized this?  This is a guy who's more thorough than Iron Man, so how has he not that his biggest rival was actually three different men?  Well, the way I see it, there are two big possibilities.
#1 There aren't three Joker's, there are three aspect or personalities for the Joker that are what causes his change from a playful thief, to vicious killer, to obsessed psycho.  He sees his different personalities as different people, and that how the Mobius Chair see's him too.
Or #2 The three Joker's are all from different timelines, and all somehow ended up in the current timeline.  I honestly think this is the most likely, since DC is littered with stuff about time travel and alternate timelines and stuff like that.
That's all I really have to say about the Three Jokers and I'll see you again next Monday with my Top 10 Favourite Batman Villains (Don't worry, the Joker only gets one spot)!
