...that Jared Leto's Joker might be Jason Todd.
The main theory behind this is
detailed in text-only in the Reddit thread that apparently spawned it, and most of that is pretty well summed up in
this article from Dorkly which also has images in it, but this is the latest image that's been adding fuel to that fire -- Joker has two scars on his shoulders that match the locations of bullet holes in Robin's costume from the graffiti'd Robin suit in the
Dawn of Justice trailer.
The parts that I think are most interesting are that it could give a good explanation for are these:
• Jared Leto's Joker being as physically muscular as he is, since he used to be Robin.
• His teeth being fake, because they were replaced after he got his face smashed in with a crowbar.
• The "J" tattoo is coincidentally very similar to the "J" brand that we see Jason Todd get in flashbacks in the game
Arkham Knight.
• The "damaged" tattoo would make more sense in this context, not to mention all the other over-the-top tattoos would be part of mental conditioning to push him every time he looked at himself.
• If he's actually torturing Harley in the trailer, it'd mean that he's putting her through the exact same type of conditioning that made him, thus the same tattoos, bleached skin, etc. etc. since her obsession is with the Joker and being like him.
While it might seem far fetched, this precedent has kinda been explored in a way that's not wholly dissimilar from what happened with Tim Drake in
Batman Beyond: Return of the Joker. The,
"How many good guys are left? How many stayed that way?" seems like it is another really good reason for Batman saying that. Although this also covers individuals like Harvey Dent, etc. if the Nolan-verse stuff isn't being directly referenced, this would be a prime example to hold up -- not to mention that it would make a REALLY solid connection between Batman (a big player in
Dawn of Justice) and Joker (a big player in
Suicide Squad) that they could leverage to help pull their universe together.
Overall, I think it's got some interesting potential if it's true, especially since the DCCU films are supposedly gonna center more on the Bat Family, and I think that both of those things would help to distance themselves solidly from the Nolan-verse Bat films. It'd also make for the Joker to be an incredibly personal and specific threat to the DCCU Batman since they're planning on building off of that.
I'll be happy whether or not it turns out to be true, but I think it's SUPER interesting food for thought.
