Hot Toys, maker of preternaturally quality action figures, has their line of Suicide Squad toys on display at San Diego Comic-Con, as is standard procedure. What is less standard is that one of its figures is a character that hasn’t even been hinted at in all of Suicide Squad’s vast marketing, making it a bit of a spoiler.
So technically, the figure isn’t “crazy” in the sense of “what an unexpected character!” In fact, it’s not actually a new character at all, but it’s a new figure of the Joker. My apologies for the deception, but I wanted to keep it vague for people who don’t want to know this particular spoiler...
...namely that the Joker seems like he’ll be donning his own Batman outfit for some portion of the movie. (If you enlarge the pic, you can see the skin is white, but more importantly he has the Joker’s capped teeth, so it’s definitely not Batman under the influence of Joker gas or somesuch.)
Birth Movies Death seems to have spotted it first, where they mention that all the other Suicide Squad figures are known to be in the movie, implying that presumably this one will be as well. I’ll go one step further and say that I don’t know that Hot Toys has ever created its own variant of a movie character; they stick almost entirely, if not actually entirely, to recreating specific characters/outfits/etc from movies and TV shows and etc.
Assuming the Joker does wear this in Suicide Squad, it begs the question: Where did he get it? Because it looks a lot like Batman’s real outfit, meaning the Joker would have had to steal it from him somehow. I doubt that Batman would discard a uniform—rather, I can’t imagine a situation where Batman would have to strip down and leave an intact Bat-suit behind—which implies that the Joker may have picked it up from the Batcave. Which raises a much larger set of questions...
